Mich. Admin. Code R. 408.13375 - Protective helmets
Rule 3375.
(1)
Protective helmets shall be described by impact type and electrical class. All
protective helmets shall meet either Type I or Type II requirements. All
helmets shall be further classified as meeting Class G, Class E, or Class C
electrical requirements. Helmets shall be classified as follows:
(a) Impact type protective helmets shall be
either of the following:
(i) Type I helmets
intended to reduce the force of impact resulting from a blow only to the top of
the head.
(ii) Type II helmets
intended to reduce the force of impact resulting from a blow to the top or
sides of the head.
(b)
Electrical classes for protective helmets shall be 1 of the following:
(i) Class G, general protective helmets are
intended to reduce the danger of contact with low voltage conductors. Test
samples shall be proof-tested at 2200 volts (phase to ground). This voltage is
not intended as an indication of the voltage at which the helmets protects the
wearer.
(ii) Class E, electrical
protective helmets are intended to reduce the danger of contact with higher
voltage conductors. Test samples shall be proof-tested at 20,000 volts (phase
to ground). This voltage is not intended as an indication of the voltage at
which the helmet protects the wearer.
(iii) Class C, conductive protective helmets
are not intended to provide protection against contact with electrical
hazards.
(2)
A metallic head device shall not be furnished by an employer or used by an
employee for head protection, except where it has been determined that the use
of other types of protective helmets or safety hats or caps is impractical,
such as where chemical reaction will cause the deterioration of other types of
head protection.
(3) A protective
helmet furnished by an employer shall be identified on the inside of the shell
with the name of the manufacturer.
(4) When used in conjunction with protective
helmets, faceshields, welding helmets, and goggles shall be in compliance with
the requirements in these rules, and hearing protection shall be in compliance
with Occupational Health Standard Part 380 "Occupational Noise Exposure," as
referenced in
R
408.13301a.
(5) Winter liners and chin straps used in
conjunction with class E helmets for high-voltage protection shall not contain
any metallic parts or other conductive materials.
(6) Winter liners and chin straps used in
areas where there is a danger of ignition from heat, flame, or chemical
reaction shall be made of materials that are non-burning or flame
retardant.
(7) Bump hats or caps or
other limited-protection devices shall not be used as a substitute for
protective helmets for the hazards described in
R
408.13370.
(8) An employer shall ensure that protective
helmets designed to reduce electrical shock hazard shall be worn by each
affected employee who is near exposed electrical conductors that could come in
contact with the employees head.
