How often should rubber insulating gloves be tested ?
The answer to this question depends on which province you live in. Some provinces have specific laws concerning the testing of gloves, others have no laws at all. A good source of information on this question would be your local electrical utility. Most utilities have excellent safety programs that include stringent glove testing, and if your province does not have specific requirements, their advice can be valuable when developing your glove safety protocols.
CSA Z462 requires that all gloves be tested every six months. A general rule of thumb concerning testing is that lower voltage gloves (Class 0 and 00) are tested every six months, and all other gloves are tested every three months.
When should rubber insulating gloves be inspected by the user?
Rubber insulating gloves should be visually inspected before each day’s use and after any action that could be expected to cause damage to the glove. Look for signs of physical damage (punctures, cuts, nicks, cracks, scratches and abrasions), chemical deterioration (swelling softness, hardening stickiness), ozone deteriorations, and other irregularities. Air-expand gloves no more than twice their normal size. Expansion stretches the rubber, making cuts ozone damage and abrasions easy to detect. Listen for escaping air to detect holes. If a portable inflator is not available, manually inflate the glove by rolling the cuff tightly to trap air inside then apply pressure to areas of the glove to listen for escaping air. Repeat procedure with glove turned inside out. More detailed inspection procedures and defect illustrations are described in ASTM F1236 (Standard Guide for Visual Inspection of Electrical Protective Rubber Products).
