Noise in printing
Noise can be a problem in the printing industry. Specific guidance for Noise in Printing is being developed. This page identifies the problem, what you need to do and further information.
Short duration exposure to high noise levels can cause temporary hearing loss. Permanent hearing loss results from longer term exposures. Often, you don't know your hearing is being damaged until some hearing loss has happened. Some effects of noise exposure are quicker, such as developing tinnitus. This can be a permanent ringing or whooshing sound that gets worse when it is quiet.
This demonstration shows what it's like to suffer noise-induced hearing loss.
What you need to do
Control the risk of hearing damage by reducing noise exposure as low as possible if you cannot eliminate it. You must reduce daily noise exposure to at least 85 decibels (second action level) and preferably to 80 decibels (first action level) or less.
Assess noise exposure
Work out the likely noise exposure levels in your workplace for workers based on the range of jobs they do. The HSE noise calculators will help you work out the likely exposure levels.
The best way of reducing noise in the workplace is to reduce noise at source. Plan to reduce by:
- Change machines or processes to produce less noise
- Enclose noisy machines eg provide acoustic enclosures/hoods
- Separate noisy machines and processes eg separate rooms
- Implement a System for Plant maintenance which minimises noise levels
- Provide refuges for employees to reduce exposure
Provide hearing protection
If noise levels are still above the exposure levels after noise reduction provide hearing protection and make sure operators use it. Hearing protection should:
- Reduce the sound level reaching the ear to at least below 85 decibels - preferably 80
- Have a SNR (Single Number Rating) of around 20 - it stops 20 decibels of sound
- Reduce noise to no less than 70 decibels - communication difficult and warnings unheard
- Be worn properly and during exposure- train employees on fit, use, disposal, replacement
- Be comfortable- offer choice
Use the calculator on HSE noise website to check if your hearing protection gives the right level of protection.
Buy cost effective hearing protection – employees may use several pairs per day of cheap, basic earplugs, so repeated use protection may be best. Consider hearing protection with additional benefits:
- level-dependent protectors that allow easier communication during quieter intervals
- Custom moulded plugs which are more comfortable and easier to fit.
Provide Health surveillance (hearing checks) for all employees regularly exposed above the upper exposure action values (daily or weekly exposure of 85dB or peak sound pressure of 135dB) or are at risk, for example already suffer from hearing loss.
