Tom Joyce Midstate Education and Service Foundation (formerly: Midstate Central Labor Council, AFL-CIO) Did you ever notice that heavy equipment operators, laborers, and carpenters are often the noisiest bunch in the bar or at the company or union picnic? Well, they're the noisiest on the job too, what with backhoes, jackhammers, power saws, and pneumatic tools. Unlike at the bar, though, the loud and prolonged noise their tools make at the worksite can be a hazard for all of us. ________________________________________________________
Have you ever had to raise your voice to get the attention of someone working close by? Have you ever had ringing in your ears? Have you ever had a temporary loss of hearing? Do you have difficulty hearing on the telephone? Does your spouse complain that you don't listen when she or he talks? Yes to any of these questions means that you may have a hearing problem caused by exposure to dangerous levels of noise at work. Noise is no different than any other hazard that construction and maintenance workers face. It is a real hazard that can lead to real disability. And there are ways to prevent hearing loss. Protect Your Hearing
Noise levels are
measured in decibels (DB). The noise level of circular saws can be as
high as 102 decibels; jackhammers 111 decibels, and riveting on steel
130. Compare this to what OSHA allows: no more than 90 decibels averaged
over an 8-hour day, no more than 95 dB over 4 hours, with a maximum of
115 dB for 15 minutes. If these noise limits are exceeded, then your employer
is required to provide quieter machines or mufflers (called "engineering
controls" by OSHA) or rotate workers to quieter jobs (called "administrative
controls"). If these aren't enough to reduce exposure to excessive noise,
then your employer must provide hearing protection such as ear muffs or
ear plugs. And there must be a hearing conservation program, including
noise monitoring, education and hearing tests.
If the noise levels are still too high, you should wear ear muffs or ear plugs. You may have a concern that if you are wearing ear muffs you won't be able to hear the warning signal of a machine backing up toward you. This is a real concern and a real safety issue. However, ear muffs that can filter out machinery noise and allow warning yells or whistles through are available. Many people think
that if you have a hearing problem it will go away after you get away
from the noise. This is sometimes true. But often hearing problems can
become permanent, especially after several years of exposure to excessive
noise. So listen up for safety. If you listen up now, you will be able
to listen better later. |
