  6. What is the primary purpose of a Job Hazard Analysis (JHA) related to health hazards on a construction site?

    Answer: To systematically identify hazards for each task step and determine appropriate controls before work begins

    A JHA proactively identifies health and safety hazards associated with each step of a task and establishes controls to eliminate or minimize exposure before work begins.

  7. A safety technician notices workers mixing two cleaning chemicals that produce chlorine gas. The FIRST action should be:

    Answer: Stop the work, evacuate the area, and ventilate before investigating the SDS

    An immediately dangerous gas release requires stopping work and evacuation as the first action to protect workers before any other measures are taken.
