In the hierarchy of controls, an example of an administrative control is "Changes in work procedures such as written safety policies." Administrative controls focus on changing the way people work and include implementing policies, procedures, and training to reduce exposure to hazards.
Administrative controls are important for creating a safe work environment by establishing guidelines and protocols that employees must follow. In this case, implementing written safety policies dictates specific procedures that workers need to adhere to in order to minimize risks and promote safety.
Requiring the use of a local exhaust ventilation system is an example of an engineering control, which involves physically changing the workplace or tools to reduce exposure to hazards. The use of personal protective equipment falls under the category of PPE, which is the least effective control measure as it relies on the individual to use the equipment correctly and consistently.
Substituting or replacing the hazardous material is an example of another control measure known as substitution, which involves replacing a hazardous substance with a less hazardous one to minimize risks.
Overall, in the context of the question provided, "Changes in work procedures such as written safety policies" best exemplifies an administrative control as it focuses on implementing guidelines and protocols to manage and mitigate workplace hazards effectively.
