Protocols related to the effective inspection of insulating protective equipment (IPE) and insulating personal protective equipment (IPPE).
All IPE (rubber/plastic) and IPPE shall be inspected by a qualified employee prior to each use and immediately following any incident that can reasonably be suspected of causing damage.
Pre-use inspection must, at minimum, cover the following:
- All IPE/IPPE shall be inspected for any damage, wear or contamination that would compromise its ability to insulate the linemen from different potentials. If upon inspection; IPE/IPPE is found to be defective the equipment shall be identified and removed from service.
- Applicable service dates and voltage rating shall be observed.
- Insulating rubber gloves shall be given an air test along with an inspection completed by the qualified user.
- Insulating rubber sleeves shall be inspected by the qualified user.
- Ensures insulating protective equipment can be used to protect at the rated voltage.
- Provides for uniform inspection guidelines for in-service inspection of insulating protective equipment.
- Insulating Personal Protective Equipment (IPPE): Insulating rubber Gloves and Sleeves.
- Insulating Protective Equipment (IPE): Insulating rubber blankets, rubber line hose, rubber hoods, plastic covers, etc.

Frequently Asked Questions
Pre-Use Inspection of Insulating Protective Equipment
- Why are there two dates on insulating rubber goods?
- One is the test date, and where applicable there will be an issue date.
- Which date should I use?
- This will depend on the contractor and state that you are working in. If you are not sure you should ask your supervisor.
- What observed defects would prohibit the use of an insulated protective device?
- Any equipment with any of the following defects may not be used:
- A hole, tear, puncture or cut;
- Ozone cutting or ozone checking (series of interlacing cracks);
- An embedded foreign object;
- Texture changes, such as swelling, softening, hardening, or becoming sticky or inelastic;
- Any other defect that damages the insulating properties
