What is the OSHA hierarchy of controls for hazard mitigation, listed from most to least preferred?
Answer: Elimination → Substitution → Engineering controls → Administrative controls → PPE
The hierarchy of controls from most to least preferred: Elimination, Substitution, Engineering controls, Administrative controls, PPE.
What does LOTO stand for in industrial safety, and which OSHA standard governs it for general industry?
Answer: Lockout/Tagout; OSHA 29 CFR 1910.147 — Control of Hazardous Energy
LOTO (Lockout/Tagout) is the control of hazardous energy, governed by OSHA 29 CFR 1910.147 for general industry.
What is the minimum atmospheric oxygen content required for safe entry into a confined space without SCBA, per OSHA standards?
Answer: 19.5% oxygen
OSHA 1910.146 requires that confined space atmosphere have at least 19.5% oxygen before entry without SCBA. Below 19.5% is oxygen-deficient and IDLH.
When must a 'hot work permit' be obtained in a process plant, and who typically has authority to issue it?
Answer: Before any spark-producing, flame, or heat-generating work in an area where flammable materials may be present; issued by the operations/area supervisor
Hot work permits are required for any spark, flame, or heat-producing work (welding, grinding, torches) in areas with potential flammable atmosphere. Operations supervisors with facility knowledge typically issue them.
What is 'Simultaneous Operations' (SIMOPS) and why is it a safety concern in process plants?
Answer: Multiple work activities occurring in the same area at the same time, creating increased hazards from combined risks that may exceed individual activity controls
SIMOPS occurs when multiple simultaneous activities create combined hazards greater than any individual activity — for example, overhead work above active pipefitters creates dropped-object hazards.
What is the purpose of the 'Globally Harmonized System' (GHS) as it applies to hazardous chemicals in the workplace?
Answer: To standardize chemical hazard classification, labeling, and safety data sheet format internationally
GHS standardizes how chemicals are classified, labeled (with pictograms and signal words), and documented (SDS format) so the information is consistent worldwide.
