Noise Hazards

Noise is one of the most common occupational health hazards. WorkSafeBC has established occupational exposure limits (OEL) to protect workers’ hearing as well as protect their mental health. An employer must ensure that a worker is not exposed to noise levels above 85 dBA Lex daily noise exposure level or 140 dBC peak sound level.

There are two different methods that we use to test your facility’s noise levels: Noise Survey and/or Personal Sampling.  A Noise Survey shows your workers’ noise exposure by workstation and is appropriate when the noise levels are steady and workers’ movement can be followed or accompanied. It is most suitable for production or cyclical tasks when short term noise exposure are same as that for any other part of day. Lex, energy-averaged noise exposure, would be determined around each workstation.  Personal Sampling is appropriate when worker’s movement cannot be followed or accompanied, or where work pattern may be unpredictable.

Who is this for?

In heavy industrial and manufacturing environments, prolonged exposure to noise can result in noise induced hearing loss.  This is permanent and progresses constantly as noise exposure continues month after month and year after year. Annoyance, stress and interference with speech communications are also result from prolonged exposure to excessive noise.

What does it involve?

Step 1:  Scoping meeting
First things first, we want to find out your risk level!  We call this the scoping meeting.  During this step, an advisor will come out to your facility to determine if you have a combination of conditions that put you at risk.  Based on your facility, we will advise if you need a Noise Survey, Personal Sampling or a combination of both in order to evaluate the hazard(s).

Step 2: The proposal
The program administrator will send you a service proposal that will outline the costs and deliverables based on the findings from the scoping meeting.  Once this proposal is signed and returned, we can book a date for your service(s).

Step 3:  The deliverables
Our specialist advisor will complete an assessment report that includes noise exposure levels and recommendations.  A digital copy of this report will be sent to you for your records.  They will also review your existing hearing conservation program.
