generally place a burden on the employee. Negative pressure respirators restrict
breathing, some respirators can cause claustrophobia and self-contained breathing

employees who wear respirators. A physician or other licensed health care professional
operating within the scope of his/her practice needs to medically evaluate employees to
determine under what conditions they can safely wear respirators.
