The Factory & Machinery (Noise Exposure) Regulation 1989 requires factories to conduct initial exposure monitoring. The purpose is to determine whether any of employee/s is exposed to noise greater than the action level of 85 dB (A).
The said Regulations also clearly stated that all employers are to reduce and control the workers exposure to a noise level below the permissible exposure limit of 90 dB (A) for 8 working hours. The higher the sound level, the shorter the duration of exposure is permitted.
This noise exposure monitoring report was based on the data compiled and information given by the area occupier or his representatives on the monitoring day/days. As the results withdrawn were much depends on the working conditions during the day/days mentioned below, I reasonably believe that samples taken represent the greatest daily noise exposure in the workplace. Therefore it can be used as reference for worker’s daily exposure and if there are any changes in the process or machinery, then this report is considered null and void.
Area Monitoring is a procedure of identifying the noise created by the machineries within the said area which may exceed the Permissible Exposure Limit of 90 dB (A).
Our first survey was conducted by “a walk-through assessment” in order to help us to define the noise problem and provide the basis for a noise measurement and control plan. It was also a familiarization for us on the location and the names of the equipments given here. By having this assessment, it was actually an informal audit of noise source, possible noise controls and management measures to reduce noise exposure.
Subsequently, zoning will be done to identify the specific noise sources within the area. The layout of the area with machinery location is drawn. Then, the noise contours of below 85 dB (A), 85 to 90 dB (A) and above 90dB (A) are sketched on the plan and are colored for easy identifications. This is conducted by walking with the meter to the mark the distance from the noise sources for each noise contour being measured. All the points for each contour are jointed to complete the zone.
Types of noise are also recorded during this procedure.
PERSONAL EXPOSURE MONITORING
Personal noise exposure monitoring is carried out to indicate the extent of the severity of an employee’s noise exposure. Method of this monitoring are as described below.
