What is the primary purpose of a Job Safety Analysis (JSA)?
Answer: To break down a job into steps and identify potential hazards at each step
A Job Safety Analysis systematically breaks down a task into individual steps and identifies the potential hazards associated with each step, along with controls to mitigate those hazards.
When is it necessary to use a full-body harness and lanyard on a construction site?
Answer: When working at heights of 6 feet or more above a lower level in general construction
OSHA requires fall protection, including personal fall arrest systems like harnesses and lanyards, when construction workers are exposed to falls of 6 feet or more to a lower level.
What should a worker do first upon discovering an unlabeled container of liquid at a construction site?
Answer: Do not use the material and report it to the supervisor immediately
Unlabeled containers must not be used. Workers should leave the container undisturbed and immediately notify their supervisor so the contents can be properly identified and handled.
Which signal should a worker give to a crane operator to indicate 'stop' using standard hand signals?
Answer: Both arms extended outward with palms down, moving arms back and forth horizontally
The standard hand signal for 'stop' is both arms extended outward from the body with palms down, moving the arms back and forth horizontally in a sweeping motion.
What is the maximum height at which a scaffold platform can be used without guardrails?
Answer: 10 feet
OSHA requires guardrails on scaffolds when the working platform is 10 feet or more above the next lower level, which is different from the 6-foot general construction fall protection threshold.
What must be included in a site-specific safety plan before construction work begins?
Answer: A comprehensive hazard assessment, emergency procedures, PPE requirements, and training documentation
A site-specific safety plan must comprehensively address all anticipated hazards, required PPE, emergency procedures, safety training requirements, and specific controls for the work being performed.
