See the questions first
Real items, with the answer marked and the reason written out — the same format as all 420.
What does the acronym LOTO stand for in workplace safety?
Why: LOTO stands for Lockout/Tagout, a procedure to control hazardous energy during servicing and maintenance. It ensures equipment is de-energized and cannot be unexpectedly started. Each authorized worker applies their own lock so the equipment stays safe until work is done.
What does the Hazard Communication Standard (HazCom) require employers to provide about chemicals?
Why: The Hazard Communication Standard requires employers to inform and train workers about the hazardous chemicals they may be exposed to. This includes proper labeling, accessible Safety Data Sheets, and a written hazard communication program. Workers must be trained on how to protect themselves.
