Safety apparel must be selected to suit the applications and hazards that the workers who wear them need protection against. While it’s quite common to purchase ‘one-size-fits-all’ safety coveralls, for example, we can’t assume that one size fits all applications. There are situations where a single type of garment or coverall suits only specific purposes, just as there are situations where disposable coveralls are better than full-blown safety suits. Companies shouldn’t assume that just one type of safety coverall or garment is all they need to keep on hand to deal with the many hazardous materials that may be encountered in their workplace. Each of these hazards needs to be better understood before sending in people to deal with them.
