Respirators are used to protect against airborne hazards, such as dusts, mists, fumes, gases and vapours. They must fit tightly on your face, or you could breathe in hazardous substances. That's why Respirator fit testing NZ is required for all employees who need a respirator to do their jobs. Regular Fit Testing is also required once every two years under OHSA regulations. The most effective way to reduce the risk of inhaling substance is by using a respirator which provides protection from the full range of air-borne contaminants that may be present in the workplace environment. However a respirator does not create an enclosure around your head so there is always a slight leakage of air. This means some contaminants may enter a respirator and come into contact with a worker's face. A tight seal must be formed between the face and respirator to ensure that leakage is eliminated.
Noise is an important factor to consider when designing a product. It is necessary to ensure that the noise level of the product is within acceptable limits, so that it does not cause any inconvenience or discomfort to the user. Noise testing NZ is a process that helps to determine the noise level of a product. It involves measuring the noise level of the product in various conditions and then comparing it with the acceptable limit. If the noise level exceeds the limit, steps can be taken to reduce it. There are many factors that can affect the noise level of a product. These include the type of materials used, the design of the product, and the way it is operated. Noise testing helps identify these factors and take corrective action.
