BEST PRACTICE
SUBJECT: CRADLE-TO-CRADLE USE OF INSULATING RUBBER GLOVES AND SLEEVES
PRACTICE STATEMENT: Protocols related to effective use of insulating rubber gloves and sleeves.
PRACTICE DESCRIPTION:
- When employees are working on energized circuits or equipment using the rubber glove method,
rubber protective-insulating gloves and sleeves rated for the exposure of the highest nominal
voltage shall be worn cradle-to-cradle when working from an aerial platform.
- Rubber protective insulating sleeves are not required when employees are working circuits with a
potential of 600 volts or less if there is no upper arm exposure and the worker will not encroach
the 5-foot primary zone.
- The term "effective cover up" is used to describe the installation of phase-to-phase rated
insulating protective cover on energized conductors and/or equipment of different potentials when
the lineman is within reaching distance or in areas extended by handling conductive objects.
- The term "extended reach" is used to describe being within five feet of energized conductors
and/or equipment or having a conductive object within five feet of energized conductors and/or
equipment.
- Electrical class rating of the insulating rubber sleeves shall meet or exceed the electrical
class rating of the insulating rubber gloves when working on primary conductors.
- Company policies shall apply when the above conditions cannot be met. Alternative work methods
ensuring worker safety shall be identified, communicated to all affected workers, implemented and
documented as part of the Job Briefing process.
BENEFITS:
- Provides specific use requirements that are proven methods for reducing electrical contact
injuries and fatalities.
- Provides for uniform use guidelines that can be applied industry wide.
