Inspecting Equipment
To ensure electrical protective equipment performs as designed, it must be inspected for damage before each day's use and immediately following any incident that can reasonably be suspected of having caused damage. Insulating gloves must be given an air test, along with the inspection.
Defects
Insulating equipment must not be used if any of the following defects are detected:
- A hole, tear, puncture, or cut.
- Ozone cutting or ozone checking (the cutting action produced by ozone on rubber under mechanical stress into a series of interlacing cracks).
- An embedded foreign object.
- Changes in the texture including, swelling, softening, hardening, or becoming sticky or inelastic.
- Any other defect that damages the insulating properties.
Insulating equipment that is found to have defects potentially affecting its insulating properties must be taken out of service and returned for testing. It must be cleaned as needed to remove foreign substances. Additionally, it must be stored in a location and in a manner that protects it from:
- Light
- Temperature extremes
- Excessive humidity
- Ozone
- Other injurious substances and conditions
