LEARNING TASK 3 : Describe long-term hazards in the trades
Hearing loss
Exposure to loud noise over a long period of time can cause hearing loss, even if the noise is not loud enough to cause pain. Earplugs or earmuffs shall be worn in any shop or job site where the general or steady-state noise level exceeds 85 decibels. Basically, if you have to raise your voice to be heard by someone who is less than two feet away, you need to be wearing hearing protection.
