Exposure to high levels of noise can cause permanent hearing loss. Neither surgery nor a hearing aid can help correct this type of hearing loss. Short term exposure to loud noise can also cause a temporary change in hearing (your ears may feel stuffed up) or a ringing in your ears (tinnitus). These short-term problems may go away within a few minutes or hours after leaving the noise. However, repeated exposures to loud noise can lead to permanent tinnitus and/or hearing loss.

Loud noise can create physical and psychological stress, reduce productivity, interfere with communication and concentration, and contribute to workplace accidents and injuries by making it difficult to hear warning signals. The effects of noise induced hearing loss can be profound, limiting your ability to hear high frequency sounds, understand speech, and seriously impairing your ability to communicate.

Deadly Cold Exposure - Cold Weather Safety Tips - Safety Training Video Preventing cold weather injuries is important, and not just when the temperatures drop below freezing, because many cold-related injuries occur in temperatures above freezing. The key to working safely in colder temperatures starts with understanding what cold weather injuries are and how to avoid them. Although slips, trips and falls are common problems, there are other dangerous hazards resulting from unprotected exposure while working in cold weather. Chilblains, Immersion Foot, Trench Foot, Frostnip, Frostbite, Hypothermia and Dehydration are hazards that can disable you. Some of these conditions can not only lead to amputations, they are genuinely life-threatening. Your health and safety in cold weather demands that you know the hazards associated with snow, ice, falling temperatures and contact with super-cooled liquids or metals.. This safety training video outlines the health hazards that can hit us in colder weather. It covers several tips on how to spot these hazards and protect yourself.
