Question

in which workplaces are written hazard communication programs not required? where employees are exposed to hazardous chemicals where employees deal with sealed containers where employees use personal protective equipment where employees have other training

Explanation:

Written hazard - communication programs are mainly for informing employees about hazardous chemicals. When employees deal with sealed containers, if the containers remain sealed and there is no exposure risk, such programs may not be required. Exposure to hazardous chemicals (first option) clearly requires such programs. Using personal protective equipment or having other training does not exempt from having a written hazard - communication program.

Answer:

Where employees deal with sealed containers
