1.5.3.3 Hearing Protection
If noise at your site exceeds the limits established by
OSHA in
paragraph 1910.95
, entitled
"Occupational Noise Exposure"
of the
Occupational Safety and Health Standards
, you should provide ear and
or other protection to everyone near thermal spray operations to bring the
exposure within OSHA permissible, tolerable noise levels. Limit workers'
exposure to noise according to federal standards prescribed under the
Occupational Safety and Health Act.
Protect operators, nearby workers, and transient passers-by from thermal
spray noise: at the source, during its transmission, or at the receiver.
Managing any of these can solve the noise problem. Each situation
Issued: 10/11
