11. What is the IDLH (Immediately Dangerous to Life or Health) concentration for hydrogen sulfide (H₂S)? → 100 ppm
12. A new mine safety professional wants to improve hazard reporting culture. Which approach is MOST effective? → Create a confidential, non-punitive reporting system and reward hazard identification
