When should I re-test rubber insulating gloves for electrical work?
When should I re-test rubber insulating gloves for electrical work? According to OSHA (Occupational Safety and Health Administration) standards, rubber insulating gloves used for electrical work must be tested at regular intervals to ensure their safety and effectiveness. The key requirements are outlined in OSHA 29 CFR 1910.137 and ASTM F496 standards.
How often to inspect and retest rubber insulating gloves?
- Before first issue (unless they have been tested within the previous 12 months).
- Every 6 months after being issued for use.
- After any incident that may cause damage (e.g., punctures, exposure to chemicals, or extreme wear).
- If in storage for over 12 months, they must be retested before use.
Additional Best Practices
- Daily visual inspection: Workers should inspect gloves for cuts, tears, swelling, or ozone damage before each use.
- Air testing: Slightly inflating the gloves and listening for leaks is a good daily practice.
- Storage: Keep gloves away from direct sunlight, heat, chemicals, and sharp objects to extend their life.

Additionally, When buying insulated gloves for electrical work, it’s crucial to choose the right type based on OSHA standards, voltage requirements, and durability. Here’s what to look for:
1. Voltage Rating & Class
Rubber insulating gloves are categorized into six classes based on the maximum voltage they can handle. Always choose gloves that meet or exceed your working voltage.
| Class | Max AC Voltage | Max DC Voltage |
|---|---|---|
| Class 00 | 500V AC | 750V DC |
| Class 0 | 1,000V AC | 1,500V DC |
| Class 1 | 7,500V AC | 11,250V DC |
| Class 2 | 17,000V AC | 25,500V DC |
| Class 3 | 26,500V AC | 39,750V DC |
| Class 4 | 36,000V AC | 54,000V DC |
2. Compliance & Certification
Ensure gloves meet:
✅ OSHA 29 CFR 1910.137 (Electrical Protective Equipment)
✅ ASTM D120 (Standard for Rubber Insulating Gloves)
✅ ASTM F496 (Testing & Maintenance Guidelines)
3. Material & Durability
- Natural rubber for flexibility and dielectric strength
- Thickness appropriate to the class rating
- No cuts, tears, swelling, or ozone damage
4. Glove Kit – Leather Protectors & Liners
- Leather protector gloves: Worn over rubber gloves to prevent punctures and abrasions
- Cotton liners: Improve comfort and reduce sweat during extended use
5. Size & Fit
- Gloves should fit snugly without restricting movement
- Measure hand circumference and check manufacturer sizing charts
6. Testing & Expiration
- Check the date stamp: Gloves must be tested before first use and retested every 6 months
- Perform daily visual and air tests before each use
