Which of the following is NOT a requirement of a written respiratory protection program?

A written respiratory protection program must include several key components outlined by regulatory standards, primarily to ensure the safety and effectiveness of respirators in protecting workers from respiratory hazards. Among the requirements, respirator selection procedures, respirator use and maintenance procedures, and respiratory hazards training are explicitly mandated to ensure that the necessary precautions are taken for proper use, care, and understanding of the hazards involved.

While engineering controls are certainly important in the overall context of workplace safety and may complement a respiratory protection program, they are not specifically required to be included in the respiratory protection program itself. Engineering controls refer to the physical modifications made to the work environment to reduce or eliminate hazards at the source (such as ventilation systems), but the respiratory program primarily focuses on the proper selection and use of respiratory protection equipment, training associated with that equipment, and procedures for maintenance and care. Thus, engineering controls, while beneficial, do not fall under the specific requirements for a written respiratory protection program, making the choice about them correct in this context.
