5. Dynamic force presents a greater risk of strain than static force. True False 6. In underground climate, auto compression of air adds 4-60C/km to the wet bulb temperature. True False 7. An industrial machinery gives out 112 dBA of noise 1 m away from the source, which requires double hearing protection. You are a worker performing work for 8-hrs around the machinery and you are required to wear double hearing protection. An earplug which has an NRR of 29 dB and an earmuff with an NRR of 31 dB. The suggested derrating percentage of the hearing protections are 60% and 55% of the NRR, respectively. Does the double hearing protection reduce the noise level below 85 dB? True False 8. Dilated eye is an effect of critical hypothermia. True False
