Apparel and Body Protection Requirements
II. Head Areas
A. Wear an ANSI Z89.1, Protective Headwear for Industrial Workers type B or
type E hard hat that has a rating of 20,000 volts, 60 hertz for 3 minutes,
provides a suspension to 38 millimeters (1.5 inches) above the head, and can
include an optional cold weather liner and chin strap. Wear where exposed to
energized lines/equipment and falling objects such as exterior substations,
overhead and underground lines, construction sites, fuse changing, voltage
readings, and maintenance of batteries and medium-voltage equipment.
B. Wear ANSI Z87.1, Occupational and Educational Eye and Face Protection eye
and face protection with impact-resistant lenses and side shields. Contact
lenses do not provide eye protection. Face shields do not provide impact eye
protection. Filter lenses are required for radiant energy protection.
C. Use ear plugs or inserts in ear canals that provide 25 to 30 decibel attenuation
or ear caps and muffs or muffs that go over ear canals and provide 22 to 27
decibel attenuation. A combination of both can provide 35 to 37 decibel
attenuation. All need careful fitting.
D. Respiratory protection needs to be provided per the confined space entry plan
and/or the hazardous material regulated area requirement. Use NIOSH
certified device if the hazard type has a NIOSH performance requirement. Use
for emergencies only; correct hazardous atmospheric conditions with
ventilation. Requires special training and fitting.
III. Other Body Areas
A. Apply appropriate protective ointment to skin if needed for exposed areas.
Ointment should not be damaging to rubber goods.
B. Use rubber gloves where required in other chapters of this handbook. Use
leather palm gloves for protection when rubber gloves are not required. Use
welders' gloves when welding.
C. Wear ANSI Z41, Protective Footwear, P591, C75 or I75 shoes rated for 34
kilograms (75 pounds) crushing strength and having no heel or toe plates or
hobnails. Use electrically insulated shoes for de-energized line work within 3
meters (10 feet) of grounded items. Use conductive shoes where needed for
protection from static discharges.
