How often must rubber gloves be electrically tested?

• A. Every 6 months
• B. Every year
• C. Every 3 months
• D. Every 2 years

Answer: (A)

Rubber insulating gloves are tested every six months to make sure they still provide the necessary electrical insulation. Over time, even if there are no visible signs of damage, the material can develop tiny cracks, pinholes, or loss of elasticity from age, heat, ozone, or chemical exposure. These defects can seriously reduce dielectric strength and allow current to pass through under live conditions. Regular six-month testing, combined with a pre-use visual check, helps catch any hidden flaws before gloves are used on the job. The testing is done by a qualified person and follows safety standards, typically involving an air/inflatable leak check and a dielectric withstand test. If a glove fails, it must be taken out of service and replaced.
