It includes required elements such as policies, procedures, communication and training, periodic checks, and records maintenance. The standard also includes guidance on much more detailed topics such as ventilation, lighting, noise control, hazard detection and control of chemicals, ergonomic considerations and safe operational practices. The purpose of the standard is to help reduce industrial accidents, illnesses, and deaths.
