ANSI/SAE J1166 MAY90

Meets OSHA and MSHA
Requirements

When properly installed and maintained, the cab offered

by Caterpillar, when tested with doors and windows closed
according to ANSI/SAE J1166 OCT 98, meets OSHA and
MSHA requirements for operator sound exposure limits
in effects at time of manufacture.
Hearing protection may be needed when operating with
an open operator station and cab (when not properly
maintained or doors/windows open) for extended periods
or in noisy environment.
