1. NOVAX INSULATING GLOVES

2. Rubber Insulating Gloves Protection Against Mortal Risk
Even household power is lethal
Well over 100 industrial fatalities in related to electricity according to the BLS
Careless, unqualified and unprotected workers are at high risk
Refresh basic safety awareness

3. Electrical Safety Depends On
Properly designed, installed and maintained equipment and systems
Thorough training to qualify workers for each task
De-energize and lockout/tagout circuits over 50 volts when feasible
Analysis of the hazards present or possible
Well thought out work plan
Selection of proper PPE

4. Glove Construction – Why Natural Rubber?
High Dielectric strength (good insulator)
Able to stretch and return (elastic)
Resistant to moisture, cuts, puncture and abrasion
Well suited for making seamless gloves
Relatively inexpensive compared to synthetic polymers
Very available

5. Production Process
Latex Dip Process – Rubber Particles Are in Water, Builds Film Thickness Quickly, Long Leach and Slow Drying Required, Environmentally Friendly
Solvent Dip Process – Solid Rubber is Dissolved in a Solvent, Requires Many Dips to Build Thickness with Drying Between Each Dip, Solvent Must Be Recovered

6. Design Requirements Seamless Construction Free from harmful defects
Within required dimensional specification
Able to pass specific physical and electrical tests – usually a “batch” or “lot” test
Each glove is electrically tested

8. OSHA Test Interval
– Must be electrically tested before first issue and every six months thereafter (state OSHA trumps federal if standard is tighter)
(Tele-com) – Natural rubber insulating gloves must be electrically tested before first issue, twelve months after first issue and every 9 months thereafter
Any un-issued glove that has not been tested within twelve months must be re- tested before issue.

9. When to Use Rubber Insulating Gloves
It is up to the employer to determine the risk and establish the conditions under which rubber insulating gloves are required
OSHA Regulations – (a)(1)(i) Employees working in areas where there are potential electrical hazards shall be provided with, and shall use, electrical protective equipment that is appropriate for the specific parts of the body to be protected and for the work to be performed.
NFPA - 70-E (See Chart 130.7(c)(9)(a) Hazard/Risk Category Classifications)

10. Visual Inspection
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.
Inflate to check for holes
Roll between fingers to check for ozone/uv cracking
Inspect leather protectors for damage or defects

11. Leather Protectors
Leather protectors should be shorter that the Rubber Insulating Gloves
By ½ inch for Class 00 and Class 0
By one inch multiplied by the class number for all other classes.
Leather protectors must be worn except when the need for dexterity is compelling and in the absence of cutting or puncture hazards, certain restrictions apply
Never wear leather protectors alone for electrical protection!

12. Cleaning
Wash in warm water (85° F) with mild detergent, disinfect with a small amount of chlorine bleach
Air or tumble dry at low heat (165° F)
Gloves many be dusted lightly with talc to reduce tackiness

13. Storage
Rubber insulating gloves should be stored in a glove bag, finger tips up, hung not laid flat.
Never fold rubber insulating gloves.
Leather protectors should be removed prior to storage.
Store in as dry and cool (95° F maximum) location as possible, away from sources of ozone and direct sunlight.
