71-743: The Australian Transport Advisory Council recognised the Advisory Committee on the Transport of Dangerous Goods (ACTDG) in 1970 to expand and harmonise standardised national requirements for safe transportation of Dangerous Goods . The ADGC is currently adopted through individual legislation in each in State and Territory in Australia drawing on national model legislation. ADG7 complies with international standards of importation and exportation of dangerous goods ( United Nations Recommendations on

142-478: A poison is a substance that obstructs or inhibits a nuclear reaction. Environmentally hazardous substances are not necessarily poisons, and vice versa. For example, food-industry wastewater—which may contain potato juice or milk—can be hazardous to the ecosystems of streams and rivers by consuming oxygen and causing eutrophication , but is nonhazardous to humans and not classified as a poison. Biologically speaking, any substance, if given in large enough amounts,

213-1234: A bite or sting through a venom apparatus , such as fangs or a stinger , in a process called envenomation , whereas poisons are toxins that are passively delivered by being swallowed, inhaled, or absorbed through the skin. Unantidoteable refers to toxins that cannot be neutralized by modern medical technology, regardless of their type. Industry , agriculture , and other sectors employ many poisonous substances, usually for reasons other than their toxicity to humans. (e.g. feeding chickens arsenic antihelminths ), solvents (e.g. rubbing alcohol, turpentine), cleaners (e.g. bleach, ammonia), coatings (e.g. Arsenic wallpaper), and so on. For example, many poisons are important feedstocks . The toxicity itself sometimes has economic value, when it serves agricultural purposes of weed control and pest control . Most poisonous industrial compounds have associated material safety data sheets and are classified as hazardous substances . Hazardous substances are subject to extensive regulation on production, procurement, and use in overlapping domains of occupational safety and health , public health , drinking water quality standards , air pollution , and environmental protection . Due to

284-453: A chemical defense developed by Theobroma cacao can be incidentally fatal nevertheless. Many omnivores, including humans, readily consume edible fungi , and thus many fungi have evolved to become decisively inedible , in this case as a direct defense. Chronic poisoning is long-term repeated or continuous exposure to a poison where symptoms do not occur immediately or after each exposure. The person gradually becomes ill, or becomes ill after

355-764: A description of compatibility groups. The United States Department of Transportation (DOT) regulates hazmat transportation within the territory of the US. Note : For further details, check the Dangerous Goods Transportation Regulations of the country of interest. Mitigating the risks associated with hazardous materials may require the application of safety precautions during their transport, use, storage and disposal . Most countries regulate hazardous materials by law, and they are subject to several international treaties as well. Even so, different countries may use different class diamonds for

426-681: A four digit UN number . This number, along with standardized logs of hazmat information, can be referenced by first responders (firefighters, police officers, and ambulance personnel) who can find information about the material in the Emergency Response Guidebook . Different standards usually apply for handling and marking hazmats at fixed facilities, including NFPA 704 diamond markings (a consensus standard often adopted by local governmental jurisdictions), OSHA regulations requiring chemical safety information for employees, and CPSC requirements requiring informative labeling for

497-499: A global level. Dangerous goods are assigned to UN numbers and proper shipping names according to their hazard classification and their composition. Dangerous goods commonly carried are listed in the Dangerous Goods list. Examples for UN numbers and proper shipping names are: Dangerous goods are divided into nine classes (in addition to several subcategories) on the basis of the specific chemical characteristics producing

568-926: A long latent period. Chronic poisoning most commonly occurs following exposure to poisons that bioaccumulate , or are biomagnified , such as mercury , gadolinium , and lead . In 2010, poisoning resulted in about 180,000 deaths down from 200,000 in 1990. There were approximately 727,500 emergency department visits in the United States involving poisonings—3.3% of all injury-related encounters. Poisonous compounds may be useful either for their toxicity, or, more often, because of another chemical property, such as specific chemical reactivity. Poisons are widely used in industry and agriculture, as chemical reagents, solvents or complexing reagents, e.g. carbon monoxide , methanol and sodium cyanide , respectively. They are less common in household use, with occasional exceptions such as ammonia and methanol . For instance, phosgene

639-447: A poison as such, but to turn the body's natural defenses against itself. Poison can also enter the body through faulty medical implants , or by injection (which is the basis of lethal injection in the context of capital punishment ). In 2013, 3.3 million cases of unintentional human poisonings occurred. This resulted in 98,000 deaths worldwide, down from 120,000 deaths in 1990. In modern society, cases of suspicious death elicit

710-465: A poison or not may depend on the amount, the circumstances, and what living things are present. Poisoning could be accidental or deliberate, and if the cause can be identified there may be ways to neutralise the effects or minimise the symptoms . In biology , a poison is a chemical substance causing death , injury or harm to organisms or their parts. In medicine , poisons are a kind of toxin that are delivered passively, not actively. In industry

781-451: A primary food source. Selective toxicity, controlled application, and controlled biodegradation are major challenges in herbicide and pesticide development and in chemical engineering generally, as all lifeforms on earth share an underlying biochemistry ; organisms exceptional in their environmental resilience are classified as extremophiles , these for the most part exhibiting radically different susceptibilities. A poison which enters

852-595: A variety of natural or synthetic substances. Substances that destroy tissue but do not absorb, such as lye , are classified as corrosives rather than poisons. Acute poisoning is exposure to a poison on one occasion or during a short period of time. Symptoms develop in close relation to the exposure. Absorption of a poison is necessary for systemic poisoning. Furthermore, many common household medications are not labeled with skull and crossbones, although they can cause severe illness or even death. Poisoning can be caused by excessive consumption of generally safe substances, as in

923-753: Is hazardous waste which is waste that has substantial or potential threats to public health or the environment . Hazardous materials are often subject to chemical regulations . Hazmat teams are personnel specially trained to handle dangerous goods, which include materials that are radioactive , flammable , explosive , corrosive , oxidizing , asphyxiating , biohazardous , toxic , poisonous , pathogenic , or allergenic . Also included are physical conditions such as compressed gases and liquids or hot materials, including all goods containing such materials or chemicals, or may have other characteristics that render them hazardous in specific circumstances. Dangerous goods are often indicated by diamond-shaped signage on

994-691: Is a highly reactive nucleophile acceptor, which makes it an excellent reagent for polymerizing diols and diamines to produce polycarbonate and polyurethane plastics. For this use, millions of tons are produced annually. However, the same reactivity makes it also highly reactive towards proteins in human tissue and thus highly toxic. In fact, phosgene has been used as a chemical weapon . It can be contrasted with mustard gas , which has only been produced for chemical weapons uses, as it has no particular industrial use. Biocides need not be poisonous to humans, because they can target metabolic pathways absent in humans, leaving only incidental toxicity. For instance,

1065-641: Is also distinct from toxicity itself. For instance, the preservative thiomersal used in vaccines is toxic, but the quantity administered in a single shot is negligible. Throughout human history, intentional application of poison has been used as a method of murder , pest-control , suicide , and execution . As a method of execution, poison has been ingested, as the ancient Athenians did (see Socrates ), inhaled, as with carbon monoxide or hydrogen cyanide (see gas chamber ), injected (see lethal injection ), or even as an enema . Poison's lethal effect can be combined with its allegedly magical powers; an example

1136-400: Is any poison produced by an organism, such as the bacterial proteins that cause tetanus and botulism . A distinction between the two terms is not always observed, even among scientists. The derivative forms "toxic" and "poisonous" are synonymous. Animal poisons delivered subcutaneously (e.g., by sting or bite ) are also called venom . In normal usage, a poisonous organism is one that

1207-869: Is available from the National Chemical Emergency Centre (NCEC) website. Guidance is available from the Health and Safety Executive . New Zealand's Land Transport Rule: Dangerous Goods 2005 and the Dangerous Goods Amendment 2010 describe the rules applied to the transportation of hazardous and dangerous goods in New Zealand. The system closely follows the United Nations Recommendations on the Transport of Dangerous Goods and uses placards with Hazchem codes and UN numbers on packaging and

1278-527: Is chemically converted to toxic formaldehyde and formic acid in the liver . Many drug molecules are made toxic in the liver, and the genetic variability of certain liver enzymes makes the toxicity of many compounds differ between individuals. Exposure to radioactive substances can produce radiation poisoning , an unrelated phenomenon. Two common cases of acute natural poisoning are theobromine poisoning of dogs and cats , and mushroom poisoning in humans. Dogs and cats are not natural herbivores, but

1349-752: Is generally required includes the shipper's name and address; the consignee's name and address; descriptions of each of the dangerous goods, along with their quantity, classification, and packaging; and emergency contact information. Common formats include the one issued by the International Air Transport Association (IATA) for air shipments and the form by the International Maritime Organization (IMO) for sea cargo. A license or permit card for hazmat training must be presented when requested by officials. The international community has defined

1420-411: Is harmful to consume, but a venomous organism uses venom to kill its prey or defend itself while still alive. A single organism can be both poisonous and venomous, but it is rare. All living things produce substances to protect them from getting eaten, so the term "poison" is usually only used for substances which are poisonous to humans, while substances that mainly are poisonous to a common pathogen to

1491-532: Is normally a provincial jurisdiction. The federal government has jurisdiction over air, most marine, and most rail transport. The federal government acting centrally created the federal Transportation of Dangerous Goods Act and regulations, which provinces adopted in whole or in part via provincial transportation of dangerous goods legislation. The result is that all provinces use the federal regulations as their standard within their province; some small variances can exist because of provincial legislation. Creation of

1562-548: Is not typically possible to determine the hazard class of a substance from its UN number. An exception to this are Class 1 substances whose UN number will always begin with a 0. See List of UN numbers . Dangerous Goods Dangerous goods ( DG ), are substances that are a risk to health, safety, property or the environment during transport. Certain dangerous goods that pose risks even when not being transported are known as hazardous materials ( syllabically abbreviated as HAZMAT or hazmat ). An example for dangerous goods

1633-475: Is poisonous and can cause death. For instance, several kilograms worth of water would constitute a lethal dose . Many substances used as medications—such as fentanyl —have an LD 50 only one order of magnitude greater than the ED50 . An alternative classification distinguishes between lethal substances that provide a therapeutic value and those that do not. Poisoning can be either acute or chronic, and caused by

1704-903: Is regulated by the Hazardous Materials Transportation Act . The Resource Conservation and Recovery Act was also passed to further protect human and environmental health. The Consumer Product Safety Commission regulates hazardous materials that may be used in products sold for household and other consumer uses. Following the UN model, the DOT divides regulated hazardous materials into nine classes, some of which are further subdivided. Hazardous materials in transportation must be placarded and have specified packaging and labelling . Some materials must always be placarded, others may only require placarding in certain circumstances. Trailers of goods in transport are usually marked with

1775-526: Is the Chinese gu poison . Poison was also employed in gunpowder warfare . For example, the 14th-century Chinese text of the Huolongjing written by Jiao Yu outlined the use of a poisonous gunpowder mixture to fill cast iron grenade bombs. While arsenic is a naturally occurring environmental poison, its artificial concentrate was once nicknamed inheritance powder . In Medieval Europe, it

1846-414: Is their toxicity to various insects and other animals deemed to be pests (e.g., rats and cockroaches ). Natural pesticides have been used for this purpose for thousands of years (e.g. concentrated table salt is toxic to many slugs and snails ). Bioaccumulation of chemically-prepared agricultural insecticides is a matter of concern for the many species, especially birds , which consume insects as

1917-585: The Convention concerning International Carriage by Rail ). Many individual nations have also structured their dangerous goods transportation regulations to harmonize with the UN model in organization as well as in specific requirements. The Globally Harmonized System of Classification and Labelling of Chemicals (GHS) is an internationally agreed upon system set to replace the various classification and labeling standards used in different countries. The GHS uses consistent criteria for classification and labeling on

1988-691: The International Convention for the Safety of Life at Sea ) for transportation of dangerous goods by sea. IMO member countries have also developed the HNS Convention to provide compensation in case of dangerous goods spills in the sea. The Intergovernmental Organisation for International Carriage by Rail has developed the regulations concerning the International Carriage of Dangerous Goods by Rail ("RID", part of

2059-523: The enzymes in mitochondria that make ATP . Intravenous injection of an unnaturally high concentration of potassium chloride , such as in the execution of prisoners in parts of the United States, quickly stops the heart by eliminating the cell potential necessary for muscle contraction . Most biocides, including pesticides , are created to act as acute poisons to target organisms, although acute or less observable chronic poisoning can also occur in non-target organisms ( secondary poisoning ), including

2130-488: The food chain —whether of industrial, agricultural, or natural origin—might not be immediately toxic to the first organism that ingests the toxin, but can become further concentrated in predatory organisms further up the food chain, particularly carnivores and omnivores , especially concerning fat soluble poisons which tend to become stored in biological tissue rather than excreted in urine or other water-based effluents . Apart from food, many poisons readily enter

2201-422: The humans who apply the biocides and other beneficial organisms . For example, the herbicide 2,4-D imitates the action of a plant hormone, which makes its lethal toxicity specific to plants. Indeed, 2,4-D is not a poison, but classified as "harmful" (EU). Many substances regarded as poisons are toxic only indirectly, by toxication . An example is "wood alcohol" or methanol , which is not poisonous itself, but

2272-446: The molecular scale, when an organism is exposed to a sufficient quantity. Medicinal fields (particularly veterinary medicine ) and zoology often distinguish poisons from toxins and venoms . Both poisons and venoms are toxins, which are toxicants produced by organisms in nature. The difference between venom and poison is the delivery method of the toxin. Venoms are toxins that are actively delivered by being injected via

2343-611: The placenta during gestation, or through breast milk during nursing . In contrast, radiological damage can be passed from mother or father to offspring through genetic mutation , which—if not fatal in miscarriage or childhood , or a direct cause of infertility —can then be passed along again to a subsequent generation. Atmospheric radon is a natural radiological poison of increasing impact since humans moved from hunter-gatherer lifestyles and cave dwelling to increasingly enclosed structures able to contain radon in dangerous concentrations. The 2006 poisoning of Alexander Litvinenko

2414-435: The 18th century. The term " poison ivy ", for example, was first used in 1784 and the term " poison oak " was first used in 1743. The term " poison gas " was first used in 1915. The term "poison" is often used colloquially to describe any harmful substance—particularly corrosive substances, carcinogens , mutagens , teratogens and harmful pollutants , and to exaggerate the dangers of chemicals. Paracelsus (1493–1541),

2485-593: The Commonwealth, States and Territories. Ian Shepherd described the commission and its processes in the following terms— The work of the NRTC and the Commonwealth and States and Territories led to major reform of the regulation of the transport of dangerous goods in Australia. The new framework consisted of a national Act - the Road Transport Reform (Dangerous Goods) Act 1995, national regulations -

2556-478: The English term comes from the "...Old French poison, puison (12c., Modern French poison) "a drink", especially a medical drink, later "a (magic) potion, poisonous drink" (14c.), from Latin potionem (nominative potio) "a drinking, a drink", also "poisonous drink" (Cicero), from potare "to drink". The use of "poison" as an adjective ("poisonous") dates from the 1520s. Using the word "poison" with plant names dates from

2627-495: The Hazchem warning plate system which carries information on how an emergency service should deal with an incident. The Dangerous Goods Emergency Action Code List (EAC) lists dangerous goods; it is reviewed every two years and is an essential compliance document for all emergency services, local government and for those who may control the planning for, and prevention of, emergencies involving dangerous goods. The latest 2015 version

2698-504: The Road Transport Reform (Dangerous Goods) Regulations 1997 and a new version - the sixth edition - of the Australian Code for the Transport of Dangerous Goods by Road and Rail. The Road Transport Reform (Dangerous Goods) Act provided for— The Road Transport Reform (Dangerous Goods) Regulations were arranged "...in a logical manner starting with preliminary matters and key concepts (such as bulk and packaged) and then following in

2769-514: The Transport of Dangerous Goods ). Australian Transport Ministers in the early 1990s decided to establish a further national process to develop more consistent and uniform consistent dangerous goods transport requirements across the country. This project was driven by the National Road Transport Commission (NRTC), a Commonwealth statutory authority formed as a result of intergovernmental agreements entered into by

2840-620: The UN Recommendations on the Transport of Dangerous Goods. Australia uses the standard international UN numbers with a few slightly different signs on the back, front and sides of vehicles carrying hazardous substances. The country uses the same " Hazchem " code system as the UK to provide advisory information to emergency services personnel in the event of an emergency.

2982-465: The agencies OSHA, EPA, USCG, and NIOSH jointly published the first Hazardous Waste Operations and Emergency Response Guidance Manual which is available for download. The Environmental Protection Agency (EPA) regulates hazardous materials as they may impact the community and environment, including specific regulations for environmental cleanup and for handling and disposal of waste hazardous materials. For instance, transportation of hazardous materials

3053-520: The attention of the Coroner 's office and forensic investigators . Of increasing concern since the isolation of natural radium by Marie and Pierre Curie in 1898—and the subsequent advent of nuclear physics and nuclear technologies—are radiological poisons . These are associated with ionizing radiation , a mode of toxicity quite distinct from chemically active poisons. In mammals , chemical poisons are often passed from mother to offspring through

3124-424: The body through the skin and lungs . Hydrofluoric acid is a notorious contact poison, in addition to its corrosive damage. Naturally occurring sour gas is a fast-acting atmospheric poison, which can be released by volcanic activity or drilling rigs . Plant-based contact irritants, such as that possessed by poison ivy , are often classed as allergens rather than poisons; the effect of an allergen being not

3195-410: The case of water intoxication . Agents that act on the nervous system can paralyze in seconds or less, and include both biologically derived neurotoxins and so-called nerve gases , which may be synthesized for warfare or industry. Inhaled or ingested cyanide , used as a method of execution in gas chambers , or as a suicide method , almost instantly starves the body of energy by inhibiting

The duties of the various parties in a dangerous goods road transport transaction (consignor, prime contractor, loader, driver, etc) are set out in a clear, plain English style." The sixth edition of the Code was described in the following terms— The 1997 legislative framework

3337-650: The dangerous goods transportation regulations of the country of interest. For example, see the TDG Bulletin: Dangerous Goods Safety Marks based on the Canadian Transportation of Dangerous Goods Regulations . The statement above applies equally to all the dangerous goods classes discussed in this article. For example, the Canadian Transportation of Dangerous Goods Regulations provides

3408-406: The degree of protective packaging required for dangerous goods during transportation. One of the transport regulations is that, as an assistance during emergency situations, written instructions how to deal in such need to be carried and easily accessible in the driver's cabin. Dangerous goods shipments also require a dangerous goods transport document prepared by the shipper. The information that

3479-551: The dissemination and restrict the usage of hazardous substances, important ones being the Restriction of Hazardous Substances Directive (RoHS) and the REACH regulation. There are also long-standing European treaties such as ADR , ADN and RID that regulate the transportation of hazardous materials by road, rail, river and inland waterways, following the guide of the UN model regulations. European law distinguishes clearly between

3550-470: The father of toxicology , once wrote: "Everything is poison, there is poison in everything. Only the dose makes a thing not a poison " (see median lethal dose ). The term "poison" is also used in a figurative sense: "His brother's presence poisoned the atmosphere at the party". The law defines "poison" more strictly. Substances not legally required to carry the label "poison" can also cause a medical condition of poisoning. Some poisons are also toxins, which

3621-516: The federal regulations was coordinated by Transport Canada . Hazard classifications are based upon the UN model. Outside of federal facilities, labour standards are generally under the jurisdiction of individual provinces and territories. However, communication about hazardous materials in the workplace has been standardized across the country through Health Canada 's Workplace Hazardous Materials Information System (WHMIS) . The European Union has passed numerous directives and regulations to avoid

3692-434: The herbicide 2,4-dichlorophenoxyacetic acid is a mimic of a plant growth hormone, which causes uncontrollable growth leading to the death of the plant. Humans and animals, lacking this hormone and its receptor, are unaffected by this, and need to ingest relatively large doses before any toxicity appears. Human toxicity is, however, hard to avoid with pesticides targeting mammals, such as rodenticides . The risk from toxicity

3763-479: The increase in fear of terrorism in the early 21st century after the September 11, 2001 attacks , funding for greater hazmat-handling capabilities was increased throughout the United States, recognizing that flammable, poisonous, explosive, or radioactive substances in particular could be used for terrorist attacks. The Pipeline and Hazardous Materials Safety Administration regulates hazmat transportation within

3834-533: The item (see NFPA 704 ), its container, or the building where it is stored. The color of each diamond indicates its hazard, e.g., flammable is indicated with red, because fire and heat are generally of red color, and explosive is indicated with orange, because mixing red (flammable) with yellow (oxidizing agent) creates orange. A nonflammable and nontoxic gas is indicated with green, because all compressed air vessels were this color in France after World War II, and France

3905-469: The law of dangerous goods and the law of hazardous materials. The first refers primarily to the transport of the respective goods including the interim storage, if caused by the transport. The latter describes the requirements of storage (including warehousing) and usage of hazardous materials. This distinction is important, because different directives and orders of European law are applied. The United Kingdom (and also Australia, Malaysia, and New Zealand) use

3976-557: The mechanics of molecular diffusion , many poisonous compounds rapidly diffuse into biological tissues , air, water, or soil on a molecular scale. By the principle of entropy , chemical contamination is typically costly or infeasible to reverse, unless specific chelating agents or micro-filtration processes are available. Chelating agents are often broader in scope than the acute target, and therefore their ingestion necessitates careful medical or veterinarian supervision. Pesticides are one group of substances whose prime purpose

4047-415: The organism and humans are considered antibiotics . Bacteria are for example a common adversary for Penicillium chrysogenum mold and humans, and since the mold's poison only targets bacteria, humans use it for getting rid of it in their bodies. Human antimicrobial peptides which are toxic to viruses, fungi, bacteria, and cancerous cells are considered a part of the immune system. In nuclear physics ,

4118-431: The prior ecology (especially if the prior ecology was associated with human economic value or an established industry such as shellfish harvesting). The scientific disciplines of ecology and environmental resource management study the environmental life cycle of toxic compounds and their complex, diffuse, and highly interrelated effects. The word "poison" was first used in 1200 to mean "a deadly potion or substance";

4189-410: The public, as well as wearing hazmat suits when handling hazardous materials. Poison A poison is any chemical substance that is harmful or lethal to living organisms . The term is used in a wide range of scientific fields and industries, where it is often specifically defined. It may also be applied colloquially or figuratively, with a broad sense. Whether something is considered

4260-794: The responsible management of hazardous waste and chemicals as an important part of sustainable development with Sustainable Development Goal 3 . Target 3.9 has this target with respect to hazardous chemicals: "By 2030, substantially reduce the number of deaths and illnesses from hazardous chemicals and air, water and soil pollution and contamination." Furthermore, Sustainable Development Goal 6 also mentions hazardous materials in Target 6.3: "By 2030, improve water quality by reducing pollution, eliminating dumping and minimizing release of hazardous chemicals and materials [...]." The Australian Dangerous Goods Code complies with international standards of importation and exportation of dangerous goods in line with

4331-490: The risk. Note: The graphics and text in this article representing the dangerous goods safety marks are derived from the United Nations-based system of identifying dangerous goods. Not all countries use precisely the same graphics (label, placard or text information) in their national regulations. Some use graphic symbols, but without English wording or with similar wording in their national language. Refer to

4402-644: The same product. For example, in Australia, anhydrous ammonia UN 1005 is classified as 2.3 (toxic gas) with subsidiary hazard 8 (corrosive), whereas in the U.S. it is only classified as 2.2 (non-flammable gas). People who handle dangerous goods will often wear protective equipment, and metropolitan fire departments often have a response team specifically trained to deal with accidents and spills. Persons who may come into contact with dangerous goods as part of their work are also often subject to monitoring or health surveillance to ensure that their exposure does not exceed occupational exposure limits . Laws and regulations on

4473-546: The term may be negative, something to be removed to make a thing safe, or positive, an agent to limit unwanted pests . In ecological terms , poisons introduced into the environment can later cause unwanted effects elsewhere, or in other parts of the food chain . In broad metaphorical (colloquial) usage of the term, "poison" may refer to anything deemed harmful. In biology , poisons are substances that can cause death , injury, or harm to organs , tissues , cells , and DNA usually by chemical reactions or other activity on

4544-404: The territory of the US by Title 49 of the Code of Federal Regulations . The U.S. Occupational Safety and Health Administration (OSHA) regulates the handling of hazardous materials in the workplace as well as response to hazardous-materials-related incidents, most notably through Hazardous Waste Operations and Emergency Response ( HAZWOPER ). regulations found at 29 CFR 1910.120. In 1984

Drivers that carry dangerous goods commercially, or carry quantities in excess of the rule's guidelines must obtain a D (dangerous goods) endorsement on their driver's licence . Drivers carrying quantities of goods under the rule's guidelines and for recreational or domestic purposes do not need any special endorsements. Due to

4686-411: The use and handling of hazardous materials may differ depending on the activity and status of the material. For example, one set of requirements may apply to their use in the workplace while a different set of requirements may apply to spill response, sale for consumer use, or transportation. Most countries regulate some aspect of hazardous materials. Packing groups are used for the purpose of determining

4757-437: Was a notable use of radiological assassination, presumably meant to evade the normal investigation of chemical poisons. Poisons widely dispersed into the environment are known as pollution . These are often of human origin , but pollution can also include unwanted biological processes such as toxic red tide , or acute changes to the natural chemical environment attributed to invasive species , which are toxic or detrimental to

4828-600: Was common for monarchs to employ personal food tasters to thwart royal assassination , in the dawning age of the Apothecary . The term poison is also used in a figurative sense. The slang sense of alcoholic drink is first attested 1805, American English (e.g., a bartender might ask a customer "what's your poison?" or "Pick your poison"). Figurative use of the term dates from the late 15th century. Figuratively referring to persons as poison dates from 1910. The figurative term poison-pen letter became well known in 1913 by

4899-423: Was notable for introducing the chain of responsibility concept into Australian transport law. The concept involves the design of policy and law which allocates responsibility under threat of criminal sanction to those persons who are in the best position to prevent and manage risks. Its introduction into the dangerous goods framework was described as follows— The seventh edition of Australian Dangerous Goods Code

4970-411: Was released in 2008. However, the sixth edition of Australian Dangerous Goods Code still applies as a substitute to the 7th edition for a period still not decided by governments. The structure of ADG6 which was established in 1998 differs from the current ADG7. Australia is establishing a separate dangerous goods regulation for road and rail transport. Each class is assigned a 4 digit UN number . It

The United Nations Economic and Social Council issues the UN Recommendations on the Transport of Dangerous Goods , which form the basis for most regional, national, and international regulatory schemes. For instance, the International Civil Aviation Organization has developed dangerous goods regulations for air transport of hazardous materials that are based upon
