The Control of Noise at Work Regulations 2005 require all employers to reduce or prevent the risks to health and safety from noise exposure at work. Noise levels must be monitored in all workplaces where there is a potential to exceed the levels set in the Regulations and steps taken to protect employees from hearing loss due to excessive noise.
The Castle Group Legislation Starter Pack gives you the chance to begin the work in adhering to the Control of Noise at Work Regulations 2005 and make regular checks on noise levels in your workplace.
The kit contains a GA216I Integrating Sound Level Meter for noise level checks, GA257B Industrial Dosemeter to monitor employee personal exposure to noise levels and a GA612 Class 2 calibrator to check the sound meter and dosemeter before and after measuring.
The Legislation Starter Pack is the ideal introduction to cost effective noise risk assessment for smaller businesses.
