Awareness education only. This lesson does not qualify or authorize electrical work, equipment testing, grounding, or rescue. Use employer training and procedures for assigned duties.
A pair of insulating gloves has the expected marking and a recent test date. During inspection, damage is noticed. The date does not overrule the condition of the equipment in front of the worker.
Application, present condition, and test evidence are separate checks. Rubber goods belong in an employer-controlled protective-equipment program, with appropriate accessories, care, and trained inspection.
Do not select a class from an incomplete voltage
OSHA 1910.137 Table I-4 gives maximum use voltages and important conditions. On multiphase circuits, the default voltage basis is phase-to-phase; the rule identifies circumstances in which phase-to-ground voltage can be used. A familiar phase-to-ground value alone does not establish the applicable class.
Procurement should obtain the approved class, type, size, and application requirements from engineering and safety. A higher number on a substitute is not a complete application review. Insulating gloves, protectors, sleeves, and other protections must be considered under the applicable requirements.
Inspection does not disappear between tests
OSHA requires inspection before each day’s use and after incidents that could reasonably have caused damage, with an air test for insulating gloves. Follow the employer and manufacturer procedures; they may impose additional checks.
Damage or questionable insulating condition requires removal from service and disposition under the program. Do not use this lesson as a repair method. A recent laboratory test cannot guarantee that subsequent handling or storage caused no damage.
Read testing intervals with their conditions
Table I-5 includes periodic electrical testing intervals of six months for gloves and twelve months for sleeves, along with testing before first issue and other retest triggers. Tested but unissued equipment has a separate condition concerning the age of its test. Read those conditions with the interval instead of treating the interval as a standalone release rule.
For a buyer or storeroom manager, the practical task is preserving equipment identity, records, proper storage, and replacement stock. Use the safety equipment procurement worksheet to assign those responsibilities without making a field selection.
