Companies with job sites in which fumes, dust, gases, vapors, or other potentially harmful particulates are present should have an air safety program as part of their overall safety and health program. The program should have at least the following elements:
 Accurate hazard identification and analysis procedures to determine what types of particulates are present and in what concentration
 Standard operating procedures (in writing) for all elements of the air safety program
 Respirators that are appropriate in terms of the types of hazards present and that are included in 42 CFR Part 48
 Training including fit testing, limitations, use, and maintenance of respirators
 Standard procedures for routine procedures and storage respirators
