The lower of the two levels of
daily or
weekly personal noise exposure or of
peak sound pressure which, if reached or exceeded, require specified action to be taken to reduce
risk.
The lower exposure action values are:
(a) a
daily or
weekly personal noise exposure of 80 dB (A-weighted); and
(b) a
peak sound pressure of 135 dB (C-weighted).
An
employer who carries out work which is liable to expose any
employees to
noise at or above a lower exposure action value shall make a suitable and sufficient
assessment of the risk from that noise to the health and safety of those employees.
An
employer who carries out work which is likely to expose any
employees to noise at or above a lower exposure action value shall make
personal hearing protectors available upon request to any employee who is so exposed.
Where his employees are exposed to noise which is likely to be at or above a lower exposure action value, the employer shall provide those employees and their representatives with suitable and sufficient
information, instruction and
training.
