74-411: A cabana is a type of shelter often found near beaches or pools. A cabana can be used to relax in the shade or change clothes. A cabana bathroom is a bathroom attached to a building or a house that is commonly used by swimmers and beachgoers. Bathroom A bathroom is a room in which people wash their bodies or parts thereof. It can contain one or more of the following plumbing fixtures:

148-403: A bidet , which might be placed next to a toilet. The bathroom design must account for the use of hot and cold water, in significant quantities, for cleaning the body. The water is also used for moving solid and liquid human waste to a sewer or septic tank . Water may be splashed on the walls and floor, and hot humid air may cause condensation on cold surfaces. From a decorating point of view,

222-427: A shower and a bathtub that is adjoining to the largest bedroom; a "full bathroom" (or "full bath"), containing four plumbing fixtures: a toilet and sink , and either a bathtub with a shower, or a bathtub and a separate shower stall; "half bath" (or "powder room") containing just a toilet and sink; and "3/4 bath" containing toilet, sink, and shower, although the terms vary from market to market. In some U.S. markets,

296-723: A shower , a bathtub , a bidet , and a sink (also known as a wash basin in the UK ). The inclusion of a toilet is common. There are also specific toilet rooms , only containing a toilet (most often accompanied by the sink), which in North American English tend to be called "bathrooms", "powder rooms" or "washrooms", as euphemisms to conceal their actual purpose, while they in British and Irish English are known as just "toilets" or possibly "cloakrooms" - but also as "lavatories" when they are public . Historically, bathing

370-476: A bath or shower (or both), a toilet, and a sink. An en suite bathroom or en suite shower room is attached to, and only accessible from, a bedroom. The term ‘en suite’ is French, meaning ‘then,’ ‘later,’ or ‘next.’ A family bathroom , in British estate agent terminology, is a full bathroom not attached to a bedroom, but with its door opening onto a corridor. A Jack and Jill bathroom (or connected bathroom )

444-415: A body part with electricity that causes a sufficient current to pass through the person's tissues. Contact with energized wiring or devices is the most common cause. In cases of exposure to high voltages , such as on a power transmission tower , direct contact may not be necessary as the voltage may "jump" the air gap to the electrical device. Following an electrical injury from household current, if

518-399: A boundary. The voltage of the shock may have effects ranging from uncomfortable, to painful or even lethal. Most electric fencing is used today for agricultural fencing and other forms of animal control purposes, though it is frequently used to enhance security of restricted areas, and there exist places where lethal voltages are used. Electric shocks are used as a method of torture , since

592-500: A current over time duration curve based classification. These principles are used to determine the risks from capacitors, electric weapons, electric fences and other short pulsed low- and high-voltage electrical applications outside the medical field. Prevention of electrical injuries is one of the fundamental objectives of national electrical codes for permanently-installed electrical systems in buildings. Shock danger may be reduced by use of an extra-low voltage electrical system that

666-429: A detailed analysis of the electrical system, and appropriate protection worn if the electrical work must be performed with the electricity on. The minimum current a human can feel depends on the current type ( AC or DC ) as well as frequency for AC. A person can sense electric current as low as 1   mA ( rms ) for 60   Hz AC and as low as 5   mA for DC. At around 10   mA, AC current passing through

740-448: A few seconds. A domestic power supply voltage (110 or 230 V), 50 or 60 Hz alternating current (AC) through the chest for a duration longer than one second may induce ventricular fibrillation at currents as low as 30 milliamperes (mA). With direct current (DC), 90 to 130 mA are required at the same duration. If the current has a direct pathway to the heart (e.g., via a cardiac catheter or other kind of electrode ),

814-583: A fixed resistance model. The earliest usage of the term "electrocution" cited by the Oxford English Dictionary was an 1889 newspaper reference to the method of execution then being considered. Shortly thereafter, in 1892, the term was used in Science to refer generically to death or injury caused by electricity. The lethality of an electric shock is dependent on several variables: Other issues affecting lethality are frequency , which

888-421: A much lower current of less than 1 mA (AC or DC) can cause fibrillation. If not immediately treated by defibrillation , ventricular fibrillation is usually lethal, causing cardiac arrest , because all of the heart muscle fibres move independently instead of in the coordinated action needed for successful cardiac cycle to pump blood and maintain circulation. Short single DC pulses induce VF dependent on

962-671: A person died from electrocution between July 2000 and October 2011. In Sweden, Denmark, Finland and Norway the number of electric deaths per million inhabitants was 0.6, 0.3, 0.3 and 0.2, respectively, in the years 2007–2011. In Nigeria, analysis of Nigerian Electricity Regulatory Commission data found 126 recorded electrocution deaths and 68 serious injuries in 2020 and the first half of 2021. Most electrocutions are accidental and caused by faulty equipment or poor adherence to regulations. Some distribution companies in Nigeria have higher death rates than others; in 2017, there were 26 deaths on

1036-402: A person has no symptoms, no underlying heart problems, and is not pregnant further testing is not required. Otherwise an electrocardiogram , blood work to check the heart, and urine testing for signs of muscle breakdown may be performed. Management may involve resuscitation , pain medications, wound management, and heart rhythm monitoring . Electrical injuries affect more than 30,000 people

1110-646: A prison complex maintained by Dirección de Inteligencia Nacional , a part of the Pinochet regime. In the 1970s, during the Dirty War , the parrilla was used in Argentina. Francisco Tenório Júnior (known as Tenorinho), a Brazilian piano player, was subjected to the parrilla during the military dictatorship in Brazil . The Islamic State has used electric shocks to torture and kill captives. Advocates for

1184-519: A purifying element for both body and soul. So it was not uncommon for people to be required to cleanse themselves before entering a sacred area. Baths are recorded as part of village or town life throughout this period, with a split between steam baths in Europe and America and cold baths in Asia. Communal baths were erected in a distinctly separate area from the living quarters of the village. Nearly all of

1258-465: A result of electrical injury. Electric shock is also used as a medical therapy, under carefully controlled conditions: Mild electric shocks are also used for entertainment, especially as a practical joke for example in such devices as a shocking pen or a shocking gum . However devices such as a joy buzzer and most other machines in amusement parks today only use vibration that feels somewhat like an electric shock to someone not expecting it. It

1332-524: A separate insulation system, distinct from the insulation required for the function of the device, and intended for protection of the user from electrical shock. People and animals can be protected by installing electrical equipment out of reach of passers-by, such as on electrical transmission towers , or by installation in a electrical room only accessible to authorized persons. Stray current leakage or electrical fault current may be diverted by bonding all conductive equipment enclosures together and to

1406-409: A significant social development but also providing a public source of relaxation and rejuvenation. Here was a place where people could meet to discuss the matters of the day and enjoy entertainment. During this period there was a distinction between private and public baths, with many wealthy families having their thermal baths in their houses. Despite this they still made use of the public baths, showing

1480-875: A standard ohmmeter do not accurately represent the impedance of human skin over a significant range of conditions. For sinusoidal electrical stimulation less than 10 volts, the skin voltage-current characteristic is quasilinear. Over time, electrical characteristics can become non-linear. The time required varies from seconds to minutes, depending on stimulus, electrode placement, and individual characteristics. Between 10 volts and about 30 volts, skin exhibits non-linear but symmetric electrical characteristics. Above 20 volts, electrical characteristics are both non-linear and symmetric. Skin conductance can increase by several orders of magnitude in milliseconds. This should not be confused with dielectric breakdown , which occurs at hundreds of volts. For these reasons, current flow cannot be accurately calculated by simply applying Ohm's law using

1554-593: A steady current flow (as opposed to a shock from a capacitor or from static electricity ), shocks above 2,700 volts are often fatal, with those above 11,000 volts being usually fatal, though exceptional cases have been noted. According to the Guinness Book of World Records , seventeen-year-old Brian Latasa survived a 230,000 volt shock on the tower of an ultra-high voltage line in Griffith Park , Los Angeles on November 9, 1967. A news report of

1628-415: A tinge of yellow light. Ceiling and wall lights must be safe for use in a bathroom (electrical parts need to be splashproof) and therefore must carry appropriate certification such as IP44 . All forms of bathroom lighting should be IP44 rated as safe to use in the bathroom. The first records for the use of baths date back as far as 3000 B.C. At this time water had a strong religious value, being seen as

1702-568: A toilet, sink, and shower are considered a "full bath." In addition, there is the use of the word "bathroom" to describe a room containing a toilet and a basin, and nothing else. In Canada , "washroom" is the preferred term for such a room, the same applies to public facilities. Bathrooms often have one or more towel bars or rings for hanging towels. Some bathrooms contain a bathroom cabinet for personal hygiene products and medicines, and drawers or shelves (sometimes in column form) for storing towels and other items. Some bathrooms contain

1776-447: A worse prognosis . When the path of electric current proceeds through the head, it appears that, with sufficient current applied, loss of consciousness almost always occurs swiftly. This is borne out by some limited self-experimentation by early designers of the electric chair and by research from the field of animal husbandry , where electric stunning has been extensively studied. If ventricular fibrillation occurs (as above),

1850-466: A year in the United States and result in about 1,000 deaths. Heating due to resistance can cause extensive and deep burns . When applied to the hand, electricity can cause involuntary muscle contraction, preventing the victim from untensing their hand muscles and releasing the wire, increasing the risk for serious burns. Voltage levels of 500 to 1000 volts tend to cause internal burns due to

1924-546: Is a conductive energy device (CED), an electroshock gun popularly known by the brand name " Taser ", which fires projectiles that administer the shock through a thin, flexible wire. Although they are illegal for personal use in many jurisdictions, Tasers have been marketed to the general public. Other electroshock weapons such as stun guns, stun batons ("cattle prods"), and electroshock belts administer an electric shock by direct contact. Electric fences are barriers that use electric shocks to deter animals or people from crossing

1998-420: Is absolutely necessary, workers may be trained to use insulated or non-conductive tools, and personal protective equipment such as gloves, face shields, non-conductive boots, or cover-up mats. With proper training and equipment, live-line maintenance is routinely safely carried out on electrical transmission lines energized at hundreds of thousands of volts . There were 550 reported electrocution deaths in

2072-426: Is also used for sexual stimulation . This is usually done via devices that induces erotic electrostimulation . These devices may include a violet wand , transcutaneous electrical nerve stimulation , electrical muscle stimulation , and made-for-play units. Electroshock weapons are incapacitant weapons used for subduing a person by administering electric shock to disrupt superficial muscle functions. One type

2146-406: Is an especially dangerous source of ventricular fibrillation because it usually exceeds the let-go threshold, while not delivering enough initial energy to propel the person away from the source. However, the potential seriousness of the shock depends on paths through the body that the currents take. If the voltage is less than 200 V, then the human skin, more precisely the stratum corneum ,

2220-467: Is an issue in causing cardiac arrest or muscular spasms. Very high frequency electric current causes tissue burning, but do not stimulate the nerves strongly enough to cause cardiac arrest (see electrosurgery ). Also important is the pathway: if the current passes through the chest or head, there is an increased chance of death. From a main circuit or power distribution panel the damage is more likely to be internal, leading to cardiac arrest . Another factor

2294-443: Is non-linear and depends on many factors such as intensity, duration, history, and frequency of the electrical stimulus. Sweat gland activity, temperature, and individual variation also influence the voltage-current characteristic of skin. In addition to non-linearity, skin impedance exhibits asymmetric and time varying properties. These properties can be modeled with reasonable accuracy. Resistance measurements made at low voltage using

2368-515: Is only of second order importance to fibrillation risk in the case of ultra short contact times with direct currents. But even if the charge itself is harmless, the amount of energy being discharged still can lead to thermal and chemical hazards if its value is high enough. One example of high current electric shock which may be usually harmless is an electrostatic discharge as experienced in everyday life on door handles, car doors etc. These currents can reach values up to 60 A without harmful effects on

2442-435: Is perhaps notable that the mother of Achilles bathed him to gain his invincibility. Palaces have been uncovered throughout Greece with areas that are dedicated to bathing, spaces with ceramic bathtubs, as well as sophisticated drainage systems. Homer uses the word λοετρά, loetrá , "baths", later λουτρά, loutrá , from the verb λούειν, loúein , to bathe. The same root finds an even earlier attestation on Linear B tablets, in

2516-404: Is required, interlock devices may be used to ensure that all electrical sources are removed from the equipment before accessing normally energized parts. Administrative procedures such as lockout–tagout are used to protect workers from accidentally re-energizing equipment under repair. Where accidental contact with energized components is still possible, or where adjustment of an energized system

2590-593: Is situated between and usually shared by the occupants of two separate bedrooms. It may also have two wash basins. A wetroom is a waterproof room usually equipped with a shower; it is designed to eliminate moisture damage and is compatible with underfloor heating systems. In the United States, there is a lack of a single definition. This commonly results in discrepancies between the advertised and actual number of baths in real estate listings. Bathrooms are generally categorized as "master bathroom", containing

2664-532: Is sometimes used as an official means of capital punishment in the United States, although its use has become rare from the 1990s onward due to the adoption of lethal injection . Although some original proponents of the electric chair considered it to be a more humane execution method than hanging , shooting , poison gassing , etc., it has now generally been replaced by lethal injections in states that practice capital punishment. Modern reporting has claimed that it sometimes takes several shocks to be lethal, and that

2738-418: Is that cardiac tissue has a chronaxie (response time) of about 3 milliseconds, so electricity at frequencies of higher than about 333 Hz requires more current to cause fibrillation than is required at lower frequencies. The comparison between the dangers of alternating current at typical power transmission frequencies (i.e., 50 or 60 Hz), and direct current has been a subject of debate ever since

2812-427: Is the main contributor to the impedance of the body in the case of a macroshock —the passing of current between two contact points on the skin. The characteristics of the skin are non-linear however. If the voltage is above 450–600 V, then dielectric breakdown of the skin occurs. The protection offered by the skin is lowered by perspiration , and this is accelerated if electricity causes muscles to contract above

2886-422: Is the reason that a person may be unable to release themselves from the electrical source; if this happens at a height as on a power line they can be thrown off. Larger currents can result in tissue damage and may trigger ventricular fibrillation or cardiac arrest . If death results from an electric shock the cause of death is generally referred to as electrocution . Electric injury occurs upon contact of

2960-702: Is to be found in the excavated town of Akrotiri , on the Aegean island of Santorini (Thera). There, alabaster tubs and other bath fittings were found, along with a sophisticated twin plumbing system to transport hot and cold water separately. This was probably because of easy access to geothermic hot springs on this volcanic island. Both the Greeks and the Romans recognized the value of bathing as an important part of their lifestyles. Writers such as Homer had their heroes bathe in warm water to regain their strength; it

3034-693: Is unlikely to expose a human to dangerous levels of current. Special isolated power systems may be used in applications such as operating rooms, where electrical equipment must be used in proximity to a person unusually vulnerable to electrical shock. For electrical equipment used outdoors or in wet areas, a residual current device or ground fault circuit interrupter may provide protection from electrical current leakage. Electrical devices have non-conductive insulation preventing contact with energized wires or parts, or may have conductive metal enclosures connected to earth ground so that users will not be exposed to dangerous voltage. Double insulated devices have

3108-409: Is well established and may be multifactorial. As with any traumatic and life-threatening experience, electrical injury may result in post traumatic psychiatric disorders. There exist several non-profit research institutes that coordinate rehabilitation strategies for electrical injury survivors by connecting them with clinicians that specialize in diagnosis and treatment of various traumas that arise as

3182-618: The Brazilian military dictatorship (1964 - 1985) is detailed in the final report of the National Truth Commission , published December 10, 2014. The parrilla ( Spanish for 'grill') is a method of torture whereby the victim is strapped to a metal frame and subjected to electric shock. It has been used in a number of contexts in South America. The parrilla was commonly used at Villa Grimaldi ,

3256-450: The density of the current , tissue resistance and duration of contact. Very small currents may be imperceptible or only produce a light tingling sensation. However, a shock caused by low and otherwise harmless current could startle an individual and cause injury due to jerking away or falling. A strong electric shock can often cause painful muscle spasms severe enough to dislocate joints or even to break bones . The loss of muscle control

3330-725: The mentally ill and some psychiatrists such as Thomas Szasz have asserted that electroconvulsive therapy (ECT) is torture when used without a bona fide medical benefit against recalcitrant or non-responsive patients. The Judge Rotenberg Center in Canton , Massachusetts has been condemned for torture by the United Nations special rapporteur on torture for its use of electric shocks as punishment as part of its behavior modification program. Japanese serial killer Futoshi Matsunaga used electric shocks to control his victims. Electric shock delivered by an electric chair

3404-430: The war of the currents in the 1880s. Animal experiments conducted during this time suggested that alternating current was about twice as dangerous as direct current per unit of current flow (or per unit of applied voltage). It is sometimes suggested that human lethality is most common with alternating current at 100–250 volts; however, death has occurred below this range, with supplies as low as 42 volts. Assuming

3478-801: The Abuja grid, while the Ikeja grid caused only 2 deaths. People who survive electrical trauma may develop a host of injuries including loss of consciousness, seizures, aphasia, visual disturbances, headaches, tinnitus, paresis, and memory disturbances. Even without visible burns, electric shock survivors may be faced with long-term muscular pain and discomfort, exhaustion, headache, problems with peripheral nerve conduction and sensation, inadequate balance and coordination, among other symptoms. Electrical injury can lead to problems with neurocognitive function, affecting speed of mental processing, attention, concentration, and memory. The high frequency of psychological problems

3552-556: The US in 1993, 2.1 deaths per million inhabitants. At that time, the incidence of electrocutions was decreasing. Electrocutions in the workplace make up the majority of these fatalities. From 1980–1992, an average of 411 workers were killed each year by electrocution. Workplace deaths caused by exposure to electricity in the U.S. increased by nearly 24% between 2015 and 2019, from 134 to 166. However, workplace electrical injuries dropped 23% between 2015 and 2019 from 2,480 to 1,900. In 2019,

3626-480: The amount of charge (in mC ) transferred to the body, which makes the amplitude of the electrical stimulus independent of the exact amount of current flowing through the body for very short pulse durations. DC shocks of short duration are usually better tolerated by the heart even at high currents and rarely induce ventricular fibrillation compared to lower currents with longer duration with both DC or AC. The amount of current can easily reach very high values as amperage

3700-427: The areas (zones) around and above baths, and showers. Bathroom lighting should be uniform, and bright and must minimize glare. For all the activities like shaving, showering, grooming, etc. one must ensure equitable lighting across the entire bathroom space. The mirror area should have at least two sources of light at least 1 foot apart to eliminate any shadows on the face. Skin tones and hair color are highlighted with

3774-558: The arm of a 68-kilogram (150 lb) human can cause powerful muscle contractions; the victim is unable to voluntarily control muscles and cannot release an electrified object. This is known as the "let go threshold" and is a criterion for shock hazard in electrical regulations. The current may, if it is high enough, cause tissue damage or fibrillation which can cause cardiac arrest; more than 30 mA of AC (rms, 60 Hz) or 300–500 mA of DC at high voltage can cause fibrillation. A sustained electric shock from AC at 120 V , 60 Hz

3848-401: The bathroom presents a challenge. Ceiling, wall, and floor materials and coverings should be impervious to water and readily and easily cleaned. The use of ceramic or glass, as well as smooth plastic materials, is common in bathrooms for their ease of cleaning. Such surfaces are often cold to the touch, however, so water-resistant bath mats or even bathroom carpets may be used on the floor to make

3922-516: The blood supply to the brain is diminished, which may cause cerebral hypoxia (and its associated neurologic consequences). There are a variety of psychiatric effects that may occur as a result of electrical injuries. Behavioral changes can occur as well, even if the path of electric current did not proceed through the head. Symptoms may include: OSHA found that up to 80 percent of its electrical injuries involve thermal burns due to arcing faults. The arc flash in an electrical fault produces

3996-520: The current through the body and the duration of the current. Ohm's law states that the current drawn depends on the resistance of the body. The resistance of human skin varies from person to person and fluctuates between different times of day. The NIOSH states "Under dry conditions, the resistance offered by the human body may be as high as 100,000 ohms. Wet or broken skin may drop the body's resistance to 1,000 ohms," adding that "high-voltage electrical energy quickly breaks down human skin, reducing

4070-467: The duration and the amount of current passing through the human body. Frequency plays a role with AC and pulse DC. For example, a high frequency current has a higher ventricular fibrillation threshold than lower frequency. Also, shorter single pulses have higher thresholds than short pulses. Below 10 ms are usually believed to have a primarily charge dependent threshold and shock amplitude. Research shows that for very short electric pulse durations below 100 μs

4144-507: The earth. Current passing through the earth may also provide a hazard of electrical shock, so a ground grid may be installed around installations such as electrical substations . Lightning protection systems are primarily installed to reduce property damage by lightning strikes, but may not entirely prevent electrical shock hazards. Persons outdoors during a lightning storm may be advised to take precautions to avoid electrical shock. Where installation, or maintenance of electrical equipment

4218-512: The event stated that he was "jolted through the air, and landed across the line", and though rescued by firemen, he sustained burns over 40% of his body and was completely paralyzed except for his eyelids. The shock with the highest voltage reported survived was that of Harry F. McGrew, who came in contact with a 340,000 volt transmission line in Huntington Canyon, Utah. The severity and lethality of electric shocks generally depend on

4292-404: The heart and lungs. Electric shock which does not lead to death has been shown to cause neuropathy in some cases at the site where the current entered the body. The neurologic symptoms of electrical injury may occur immediately, which traditionally have a higher likelihood for healing, though they may also be delayed by days to years. The delayed neurologic consequences of electrical injury have

4366-689: The heart as the duration is in the order of only several ns . Another example for dangerous electrostatic discharges even without flowing directly through the body are lightning strikes and high voltage arcs. Mechanism of cardiac arrhythmias induced by electricity is not fully understood, but various biopsies have shown arrhythmogenic foci in patchy myocardial fibrosis which contained increased amount of Na+  and K+   pumps , possibly associated with transient and localized changes in sodium-potassium transport as well as their concentrations, resulting in changes in membrane potential . Electric current can cause interference with nervous control, especially over

4440-460: The human body's resistance to 500 ohms". The International Electrotechnical Commission gives the following values for the total body impedance of a hand to hand circuit for dry skin, large contact areas, 50 Hz AC currents (the columns contain the distribution of the impedance in the population percentile ; for example at 100 V 50% of the population had an impedance of 1875Ω or less): The voltage-current characteristic of human skin

4514-486: The hundreds of houses excavated had their bathing rooms. Generally located on the ground floor, the bath was made of brick, sometimes with a surrounding curb to sit on. The water drained away through a hole in the floor, down chutes or pottery pipes in the walls, and into the municipal drainage system. Even the fastidious Egyptians rarely had special bathrooms. The Roman attitudes towards bathing are well documented; they built large thermal baths ( thermae ), marking not only

4588-479: The large energy (which is proportional to the duration multiplied by the square of the voltage divided by resistance or the square of the current multiplied by the resistance) available from the source. Damage due to current is through tissue heating and/or electroporation injury. For most cases of high-energy electrical trauma, the Joule heating in the deeper tissues along the extremity will reach damaging temperatures in

4662-590: The large pools that often come to mind when one imagines the Roman baths ; the earliest surviving bathtub dates back to 1700 B.C and hails from the Palace of Knossos in Crete. What is remarkable about this tub is not only the similarity with the baths of today but also how the plumbing works surrounding it differ so little from modern models. A more advanced prehistoric (15th century BC and before) system of baths and plumbing

4736-446: The let-go threshold for a sustained period of time. If an electrical circuit is established by electrodes introduced in the body, bypassing the skin, then the potential for lethality is much higher if a circuit through the heart is established. This is known as a microshock . Currents of only 10  μ A can be sufficient to cause fibrillation in this case with a probability of 0.2%. The voltage necessary for electrocution depends on

4810-583: The name of the River Lousios ("bathing" [river]), in Arcadia . Public baths are mentioned by the comedian Aristophanes as βαλανεία, balaneía (sing.: βαλανείον, balaneíon , Latinized as balneum , a "balneary"). Throughout the 16th, 17th, and 18th centuries, the use of public baths declined gradually in the West, and private spaces were favored, thus laying the foundations for the bathroom, as it

4884-664: The received voltage and current can be controlled with precision and used to cause pain and fear without always visibly harming the victim's body. Electrical torture has been used in war and by repressive regimes since the 1930s. During the Algerian War electrical torture was used by French military forces. Amnesty International published a statement that Russian military forces in Chechnya tortured local women with electric shocks by attaching wires onto their breasts. The use of electric shocks to torture political prisoners of

4958-634: The risk of electric shock . Ground-fault circuit interrupter electrical sockets can reduce the risk of electric shock, and are required for bathroom socket installation by electrical and building codes in the United States and Canada. In some countries, such as the United Kingdom, only special sockets suitable for electric shavers and electric toothbrushes are permitted in bathrooms and are labelled as such. UK building regulations also define what type of electrical fixtures, such as light fittings (i.e. how water-/splash-proof) may be installed in

5032-411: The room more comfortable. Alternatively, the floor may be heated, possibly by strategically placing resistive electric mats under the floor tile or radiant hot water tubing close to the underside of the floor surface. Electrical appliances, such as lights, heaters, and heated towel rails, generally need to be installed as fixtures, with permanent connections rather than plugs and sockets. This minimizes

5106-419: The same type of light radiation from which electric welders protect themselves using face shields with dark glass, heavy leather gloves, and full-coverage clothing. The heat produced may cause severe burns, especially on unprotected flesh. The arc blast produced by vaporizing metallic components can break bones and damage internal organs. The degree of hazard present at a particular location can be determined by

5254-583: The top 5 states with the most workplace electrical fatalities were: (1) Texas (608); (2) California (451); (3) Florida (306); (4) New York (273); and (5) Georgia (207). A recent study conducted by the National Coroners Information System (NCIS) in Australia has revealed 321 closed case fatalities (and at least 39 case fatalities still under coronial investigation) that had been reported to Australian coroners where

5328-518: The value that they had as a public institution. The strength of the Roman Empire was telling in this respect; imports from throughout the world allowed Roman citizens to enjoy ointments, incense, combs, and mirrors. The partially reconstructed ruins can still be seen today, for example at Roman Baths (Bath) in Bath, England , then part of Roman Britain . Not all ancient baths were in the style of

5402-625: Was often a collective activity, which took place in public baths . In some countries, the shared social aspect of cleansing the body is still important, for example with sento in Japan and, throughout the Islamic world, the hammam (also known in the West as a "Turkish bath"). The term for the place used to clean the body varies around the English-speaking world , as does the design of the room itself. A full bathroom generally contains
