We also operate a new service called Workplace Exposure NI. Workplace exposure describes any exposure by personnel of a workforce to noise, air/dust or vibrations. Our trained experts can monitor these exposures (sometimes called Occupational Monitoring). This is important as the workplace air, noise and vibrations could become hazards for employees health. As an employer, it is necessary to ensure that you comply with regulations. We compare exposure results against exposure standards to see if you have provided adequate protection.
