straight forward health and safty advice
Your hearing is valuable to you, however if you are subject to loud noises,
your hearing may be damaged
This damage may be short term and your hearing can recover, but if the noise is very loud or occurs
over a considerable period, your may not fully recover your hearing.
If you are in a noisy area where two people standing 2 metres (6ft 6ins) apart would have difficulty
in hearing each other speaking in a normal voice, or have to shout to be heard; or if you are using
noisy powered tools or machinery for more than half an hour each day, then your hearing
could be damaged. You should use suitable ear protection in these circumstances.
Some work areas may be designated as “hearing protection zones” and be marked
with signs. You must use hearing protection when working in, or entering the zone –
failure to do so, will damage your hearing.
Items of plant and equipment that may damage your hearing are
generally marked to show that hearing protection should be worn when
near them, or while using them. Although not marked, some hand held power
tools may be very loud if they are used near your ear, drilling near your head, for
example. Follow the 2 metre rule given above, if people have to shout to make
you hear, use ear protection.
People often experience temporary deafness after leaving a noisy place.
Although hearing recovers within a few hours, this should not be ignored. It is a
sign that if you continue to be exposed to the noise, your hearing could be permanently damaged.
Permanent hearing damage can also be caused immediately by sudden, extremely loud, explosive
noises, e.g. from guns or cartridge-operated machines; but hearing loss is usually gradual because
of prolonged exposure to noise.
Remember, simple things like switching off machines when they are not in use, and checking all
bolts, fixings, removable covers, etc are kept tight to prevent vibration and rattling noises, all
help to keep noise levels down.
