Electrical Hazards Controlling Electrical Hazards (OSHA 3075— 2002). 

Protection from electrical hazards is one way to prevent accidents caused by electric current. Protective methods to control electrical hazards include insulation, electrical protective devices, guarding, grounding, personal protective equipment (PPE), and safe work practices. 

Everyone has the right to work in a safe environment. Through cooperative efforts, employers and employees can learn to identify and eliminate or control electrical hazards. 

The purpose of this book is to assist the user in controlling the hazards associated with the generation, accumulation, and discharge of static electricity by presenting... 

While some video display screens such as liquid crystal, gas plasma or vacuum fluorescent displays do not present the same charged screen hazards as CRTs, this does not imply that they are safe for use in hazardous locations. This requires special design and certification for use with a given flammable atmosphere. Non-certified equipment used in locations classified as hazardous under Article 500 of NFPA 70 National Electrical Code require a purged or pressurized enclosure to control ignition hazards as described in NFPA 496 Standard for Purged and Pressurized Enclosures for Electrical Equipment. The screen in this case is located behind a window in the enclosure. 

Behavior in Fire Vapors are heavier than air and may travel considerable distances to a source of ignition and flash back. Fires are difficult to control because of recognition Ignition Temperature (deg. F) 446 Electrical Hazard. Not pertinent Burning Rate 4.4 mm/rnin. Chemical Reactivity Reactivity with Water No reaction Reactivity with Common Materials No reactions Stability During Transport Stable Neutralizing Agents for Acids and Caustics Not pertinent Polymerization May occur in the presence of heat, acids or alkalis Inhibitor of Polymerization Not pertinent. 

As in the example of electric arc furnace waste in the previous section, this result for a hazardous waste that contains heavy metals indicates the importance of an intention to maintain perpetual institutional control over hazardous waste disposal sites in allowing the waste to be classified as low-hazard. 

Note A discussion of the pneumatic loading system and the hazards involved is presented in the DuPont Technical Bulletin, entitled "Static Electricity Hazards and Their Control in Pneumatic Loading Systems ... 

International Organization for Standardization and the International Electrotechnical Commission. Over 1000 companies are members of the ANSI. One of its primary concerns is safety in such fields as hazardous chemicals, protective clothing, welding, fire control, electricity and construction operations, blasting, etc. Its address is 1819 L Street, NW, Washington, DC 20036.

Colour coded red with black colour zone - these are suitable for class B type fires and are also ideal for electrical hazards because CO is non-conductive. CO is an extremely fast fire control medium. These extinguishers deliver a powerful concentration of CO gas under great pressure, which smothers the flames very rapidly by displacing air from the local area of the fire. CO is a non-toxic, non-corrosive gas that is... 

Control of Hazardous Energy (Lock out/Tag out) 29 CFR 1910.147 Worker protection from electrical and other stored energy hazards ... 

You need to instill in your employees a healthy respect for electricity and its power. Safe work practices are essential. Training can ensure your employees recognize electrical hazards and use safe work practices to control or eliminate those hazards. 

As with all forms of energy, electricity has certain hazards associated with it. The goal is to eliminate or control these hazards. 

Electricity and electrical equipment create or contribute to several hazards. The most common ones are electric shock, heat, fire, and explosion. Electricity may produce other hazards indirectly. For example, when electricity energizes equipment, mechanical hazards may result. Some electrically powered devices produce harmful levels of X rays, micro-waves, or laser light. Certain equipment may create dangers from magnetic fields. Haddon s energy theory (see Chapter 9) helps people analyze electrical hazards and identify controls.
