When it comes to ‘Noise’ there is more to the definition than just sound being produced by someone or something.  When working on a construction site ‘Noise’ is an unwanted sound that may have a harmful effect. Noise can affect you psychologically, startling you or annoying you, or disrupting your concentration and subsequently your work. Noise can interfere with vital communication between you and another electrician during a specific task. Prolonged exposure to high levels of noise can damage your hearing. Ear plugs are provided to you for use when needed. Hearing loss is a gradual process, and by the time you notice the difference it may be too late. Always think ahead for your safety.
