Last revised March 19, 2015 Electrical Department – EQUAL CODE: EL304Care, Use, and Maintenance of Rubber Insulating Gloves
Scope • This presentation applies to the following occupations: • Maintenance Electrician • Electrical Apprentice • Instrumentation Technician • Power Protection and Control Serviceman • Power Line Technician • Combustion Serviceman
Purpose • To provide the user of the equipment with the proper instruction for the care, use and selection of rubber insulating gloves. • Rubber insulating gloves are to be used when: • Arc flash protection is required; • Live testing and trouble-shooting while holding a meter or meter test leads; • Establishing a safe work zone; • Installing protective grounds; • Changing of High Voltage fuses; • Used as recommended under EUSA rules for safe limits of approach; • When working on systems above 50 volts.
Tools and Equipment Class 0 Gloves Class 2 Gloves 5
Preparation • Testing of this equipment should be done in an area that is • Clean • Low noise • With adequate lighting
Use, Care & Maintenance • Rubber gloves should never be used without protective covers. • The protective cover should match the class of rubber glove being used. • The distance which the rubber glove cuff is exposed from the leather is listed in the equipment description for this procedure. • In a clean well illuminated area remove the gloves from the carrying case. • Remove the rubber gloves from their leather protectors. • Completely inspect the carrying bag to ensure there is no dirt or foreign objects in the bag which could potentially damage the gloves. • Inspect the leather gloves for dirt and damage.
Use, Care & Maintenance • Rubber gloves must be inspected before use, and any time you suspect the gloves may have been damaged. • Protective covers are inspected to detect cuts, holes, and broken beads, particles of dirt, wood chips, grease, oil, or small bits of wire inside and/or embedded in the cover. • The field inspection of rubber gloves includes a visual and air test. • Turn the rubber gloves inside out and roll the cuff to trap air in the finger and palm areas. • Look, listen, and feel for air escaping from possible punctures. • At the same time, the worker should look for any abrasions and cuts. • Air should be held in the gloves for 10-15 sec.
Chemical AttackThis photo shows swelling caused by oils and other petroleum compounds. Cracking & CuttingShown above is the damage caused by prolonged folding or compressing. Use, Care & Maintenance
Snags Damage shown here is due to wood and metal splinters and other sharp objects. UV Checking Storing in areas exposed to prolonged sunlight causes UV checking. Use, Care & Maintenance
Avoid Storing Inside Out Gloves should never be stored inside out. Storing gloves reversed strains the rubber severely and causes ozone cutting. Avoid Folding GlovesThe strain on rubber at a folded point is equal to stretching the glove to twice its length. Use, Care & Maintenance
Use, Care & Maintenance • Turn the rubber gloves right side out, then repeat the air test and visual inspection. • The field inspection should include the inspection of the last tested date on the cuff of the gloves. • Class 00 and Class 0 gloves must be retested or replaced every year or sooner • Class 2 gloves must be retested or replaced every 90 days or every 6months (refer to procedure for details) • Rings, watches, and similar jewelry must be removed before inspection and use. • These items could create stress or abrasion causing the rubber to prematurely break down.
Use, Care & Maintenance • Rubber gloves, being made of natural rubber, are subject to corona cutting, and care must be exercised with regard to storage. They must be stored • In their natural position, • In a properly sized rubber glove bag, • Preferably hanging up, • Not stuffed under other equipment or tools. Storage should also be • in a cool, dry location • away from electrical sources and fluorescent lighting. When not in use, rubber gloves must not be left exposed to direct sunlight for any appreciable duration.
Use, Care & Maintenance • It is important to remember to: • wear the proper glove for the voltage, • know what system you are working on, and wear any additional PPE as required for arc flash protection. • If the gloves are found not to pass any of these tests, • do not use them, • report the failure to your supervisor, and • return the gloves to your supervisor for proper disposal and replacement.
