or tools can expose you to live electrical parts. A damaged tool may not be grounded properly, so the housing of the tool may be ener- gized, causing you to receive a shock. Improperly grounded metal switch plates and ceiling lights are especially hazardous in wet con- ditions. If you touch a live electrical component with an uninsulated hand tool, you are more likely to receive a shock when standing in water.
But remember: you don’t have to be standing in water to be electro- cuted. Wet clothing, high humidity, and perspiration reduce resis- tance and increase your chances of being electrocuted. You need to recognize that all wet conditions are hazards.
❚ An electrical circuit in a damp place without a GFCI is danger- ous! A GFCI reduces the dange .
In addition to electrical hazards, other types of hazards are present at job sites. Remember that all of these hazards can be controlled.
❚ There are non-electrical hazards at job sites, too.
❑ There may be chemical hazards. Solvents and other substances may be poisonous or cause disease.
❑ Frequent overhead work can cause tendinitis (inflammation) in your shoulders.
Overhead work can cause long-term shoulder pain.
