Electrically Insulated Gloves - Inspect
Visually inspect insulated gloves and leather protectors prior to each use.
•
Check for any signs of physical damage or chemical deterioration such as swelling, softness, hardening,
stickiness, ozone deterioration, or sun-checking from prolonged exposure to sunlight.
•
Check whether red or yellow inner layer shows through black outer layer, indicating gloves have been cut or
snagged. If damaged at all, do not use them.
•
Check leather protectors. Look for metal particles, imbedded wire, abrasive materials, or any substance
that could cause puncture, abrasion, contamination, or deterioration. Adequate flashover distance of 2˝
(5 cm) between the top of protector and the bead of rubber glove should be maintained. Minimum uncovered
distance must be 1˝ (2.5 cm) above the protector cuff top for each 10,000 volts.
•
Check insides of each glove and air test for pinholes:
Step 1:
Place glove on your hand, and pull cuff up over your fingers, turning glove inside out.
Step 2:
Holding glove downward, grasp cuff and twirl it upward toward your body to close the cuff.
Step 3:
Squeeze rolled cuff into a “U” shape to trap air inside glove. Hold cuff with one hand and squeeze glove
with your other hand. Hold glove near your ear and listen and feel for air escaping through a hole. Pop
out glove fingers by squeezing inflated glove and check for damage.
Step 4:
Turn glove right side out.
Step 5:
Repeat with other glove.
