Q: What is Job Safety Analysis (JSA)?
A: A method to identify and control or eliminate job hazards before they occur.
Q: What are the three stages of Job Safety Analysis?
A: 1) Identify job steps, 2) Identify hazards for each step, 3) Determine preventative measures for each hazard.
Q: What are common areas of hazards for electricians?
A: Energized equipment, working at elevations, handling heavy materials, confined spaces, and extreme temperatures
Q: What is “Hot Work”?
A: Tasks that could cause a fire, such as welding, grinding, or drilling near combustible materials.
Q: What are the steps for performing “Hot Work” safely?
A: Sweep the area clean, have a fire extinguisher ready, fill out a permit, wear PPE, and monitor for 30 minutes post-work and then keep an eye on it every hour for 4 hours

Q: What are the workers’ responsibilities for safety?
A: Protect health and safety, wear protective gear, report hazards, and refuse unsafe work(B2-Lt 03).
Q: What is the Occupational Health and Safety (OHS) Regulation?
A: A legal document outlining workplace safety requirements, divided into core, hazard, and industry-specific parts(B2-Lt 03).
Q: What should be included in a noise control program according to OHS regulations?
A: Noise measurement, education, engineered controls, hearing protection, and hearing testing(B2-Lt 03).
Q: What are employers’ responsibilities regarding PPE?
A: Provide PPE at no cost, ensure it’s used correctly, and check for hazards like loose clothing or jewelry(B2-Lt 03).
Q: What defines a confined space?
A: An area not designed for continuous human occupancy that requires a standby person to monitor workers every 20 minutes(B2-Lt 03).
Q: What are the steps for lockout safety?
A: Lock out energy sources, maintain control of keys, and remove locks after work(B2-Lt 03).
Q: What must be done with unsafe tools and machinery?
A: They must be removed from the jobsite(B2-Lt 03).
Q: What does the OHS regulation require for working on low voltage systems?
A: Systems must be disconnected unless it’s unreasonable, and appropriate PPE must be used
Q: What is the requirement for GFCIs during construction?
A: GFCIs must be used on circuits for portable electrical equipment used outdoors or in damp locations(B2-Lt 03).
