Respirator user training from the 1930s

This clip is part of an early respirator training film. Today in the United States, employers must provide training to employees who are required to use respirators. The training must be comprehensive, understandable, and be done at least annually, and more often if necessary. This training should include: 1) why the respirator is necessary and how improper fit, use or maintenance can compromise its protective effect; 2) the limitations and capabilities of the respirator; 3) how to inspect, put on and remove, use and check the seals (for tight-fitting types); 4) how to maintain and store the respirator; 5) how to recognize medical signs and symptoms that may limit or prevent effective use of a respirator; and, 6) the general requirements of OSHA's respirator standard, 29 CFR 1910.134.
