THE ATTACHED NOISE SURVEYS WERE MADE BY MONITORING EMPLOYEES WITH BRUEL & KJAER TYPE 4431 DOSIMETERS TO DETERMINE NOISE EXPOSURES DURING THE NORMAL WORK DAY. 100% REPRESENTS MAXIMUM ALLOWABLE EXPOSURE, EQUIVALENT TO 85 DECIBELS (DBA) FOR A DURATION OF 8 HOURS.
DUE TO INCREASED WORK LOAD AND THEREFORE MORE NOISE EXPOSURE, NEW METHODS HAVE BEEN IMPLEMENTED TO REDUCE EMPLOYEE EXPOSURE. ATTENTION HAS BEEN GIVEN TO PROBLEM AREAS, POSITIVE ACTION HAS BEEN TAKEN, AND MUCH PROGRESS HAS BEEN MADE IN NOISE CONTROL.
IT IS THE RESPONSIBILITY OF SUPERVISION TO ENFORCE THE WEARING OF PROPER HEARING PROTECTION BY ALL PERSONNEL DURING NOISY OPERATIONS.
