  European News:
This year’s European Week of Safety and Health at Work will focus on noise in the workplace.


During 24th – 28th October 2005 many of Europe's safety professionals will be emphasising the damage to hearing from exposure to loud noise at work.

Research reports 170,000 people in the UK suffer deafness, tinnitus or other hearing conditions as a result of excessive noise at work.

The problem occurs in many workplaces, but particularly in the manufacturing and construction industries.

The campaign will  draw attention to the practical issues and ways of controlling noise in different working environments. For more information get in touch!

New Noise at Work Regulations, Will You be Ready?

The current Noise at Work Regulations are due to be replaced in February 2006.

"A long way off," some may say, but will you be ready? Or are you currently performing noise surveys which will become redundant in just over 7 months?

The following article describes the history so far and the changes to expect:

In 1993 a European proposal sought to establish a new framework for the regulation of physical agents at work: applying initially to noise, vibration, optical radiation and non-optical electromagnetic fields.

Then in 1999 the German Presidency put forward a revised proposal limiting the scope of the Directive to vibration (hand-arm and whole body) with the intention of developing further Directives on the other physical agents sequentially, rather than in a single Directive.

The main changes to the 1986 workplace noise Directive as presented under a Swedish proposal were:

  • The action values of 90 dB(A) and 85 dB(A) were reduced to a limit value of 85 dB(A) and an action value of 80 dB(A).

  • A lower action value of 112 Pa for impulse noise instead of 200PA.

  • Health surveillance by or under the responsibility of a doctor was required at 80 dB(A) and 112 Pa.

  • Hearing protection, which must be worn above 85 dB(A) and 200 PA, must reduce the risk to below 80 dB(A) and 112 Pa.

  • There was no derogation provision from the hearing protection requirements.

  • There were no exceptions for sea and air transport.

The proposal were then changed to meet the needs of the UK following negotiation. The UK negotiators achieved considerable success in reducing the burdens on industry implicit in the draft without detracting from the benefits to workers' health.

The table below, shows the main differences between the final proposal and the 1986 Directive:

Scienco are currently performing workplace noise survey to both standards, ensuring there will be no need to repeat the exercise once the new directive is adopted.
