How many different kinds of ear plugs do we need to provide for employees?

OSHA doesn’t give a specific number, but says you need to provide a “variety” of suitable hearing protectors. The reason is that different conditions may make some kinds of hearing protection more comfortable than others. For example, if it’s really warm in the work area, ear muffs may feel too hot to wear and ear plugs would be more comfortable.

On the other hand, everyone’s ear canals are shaped differently. Ear plugs just aren’t comfortable for everyone. Also, ear plugs that fit a woman’s ear canal may not be adequate for a man. You should have enough different sizes to choose from so all employees can get a good fit.

In the case of ear plugs, OSHA says that you’re in compliance if employees can select from a variety of suitable ear plugs. However, if only ear muffs will work for a particular employee, then you must provide that employee with ear muffs.
