Which of the following is not required in a written hazard communication program?

In a written hazard communication program, the primary focus is on ensuring that employees are informed about the hazards associated with the chemicals they are exposed to in the workplace. A key element of such programs includes identifying hazardous chemicals present (which is essential for staff awareness), providing training on protective measures to mitigate risks, and ensuring the distribution of safety data sheets (SDS) for all hazardous materials, which contains critical safety and handling information.

Having a list of prior hazardous material incidents, while potentially useful for internal review and training, is not a mandated component of the written hazard communication program. This is because the program's main purpose is to inform and protect employees regarding current hazards rather than to document past incidents. Thus, it does not directly contribute to the ongoing management of workplace safety concerning hazardous materials.
