Always Use and store chemicals safely. Read the label and the Material Safety Data Sheet to determine flammability and other fire hazards. Provide adequate ventilation when using and storing these substances.
Never use metallic pencils or rulers, or wear rings or metal watchbands when working with electrical equipment. This rule is very easy to forget, especially when you are showing some electrical part pointing with metallic pencil.
Report electrical hazards. Many fires start in faulty wiring and malfunctioning electrical equipment. Never attempt electrical repairs unless you are qualified and authorized.
If you are working on or near power lines, the following steps may save your life:
- Never handle a downed power line.
- Assume all power lines are energized and call the power provider to de-energize the line.
- Ground power lines on load- and supply-sides of the work area. Grounding protects from feedback electrical energy when a secondary power source, such as a portable generator, is turned on.
Check and double check safety regulations when a ladder or parts of any vehicle or mechanical equipment structure will be elevated near energized overhead power lines. Call your local electric utility for assistance. People standing on the ground may be particularly vulnerable to possible injury.
