MIL-HDBK-1110
while the visored brim which does not, is often used in confined
spaces. Hard hats must be worn in areas designated to require
them.
13.7.2.2 Bump Hats. Bump hats are made of lightweight plastic
that only protect the head from minor bumps. They should be worn
only where there are minor head hazards and never as a substitute
for a hard hat.
13.7.2.3 Hair Covers. Hair covers are made of breathable fabric
or lightweight materials and are adjustable to fit properly.
They are intended to prevent hair from becoming caught in moving
machine parts.
13.7.3
Eye Protection. Installation safety offices have eye
protection equipment available in many forms to protect eyes from
flying particles, dust, sparks, splashes, and harmful rays. The
appropriate type of eye protection should be used for each job.
13.7.3.1 Safety Glasses. Safety glasses have impact-resistant
frames and lenses that meet OSHA and American National Standards
Institute (ANSI) standards. Safety glasses may also have side
shields, cups, or tinted lens to provide additional protection.
Assistance in procuring safety glasses with prescription lenses
may be available at the safety office. Safety glasses should be
cleaned as described by the supplier and stored in a clean, dry
place available for use when needed.
13.7.3.2 Safety Goggles. Safety goggles may be impact
resistant, or provide chemical splash protection or optical
radiation protection. The appropriate goggle should be procured
and used for that purpose only. Goggles form a secure seal
around each eye to provide protection from all sides. They may
have direct or indirect ventilation to eliminate fogging.
13.7.3.3 Safety Shields. Safety shields or helmets have sheets
of clear, resistant plastic to protect the face from splash or
flying particles during grinding and welding operations or when
working with molten materials. Safety shields are ordinarily
worn with goggles or safety glasses to provide additional
protection.
13.7.4
Hearing Protection. Hearing loss occurs over time from
repeated exposure to excessively loud noises. Muffs, plugs, and
canal caps offer a variety of devices to protect our hearing.
Check the noise reduction rating (NRR) provided with each device
to determine its noise protection capabilities.
