NOISE MAPPING PRELIMINARY NOISE SURVEY • Detailed noise survey • Exposure and frequency of workers to noise • Determine areas requiring hearing protection • Determine effects of noise • Come up with control measures • Noise reduction rating • Classifying noise to come up with control measures
Personal Noise Monitoring
Measured using noise dosimeter – measures personal exposure to noise. • Personal sampling • Specific information on noise level at each employee s’ work station • Spot monitoring
Heat Stress Monitoring
• Heat tolerant testing • Heat index • Determine sources of heat • Administrative control measures • Acclimization • For continuous light, moderate and heavy work in Zimbabwe limits are 30 •c, 26.7 •c and 25 •c respectively. • PPE requirements • Information and training related to heat stress monitoring • Recommendation on hygiene practices.
