1. In human factors engineering, what is a 'forcing function'? → A physical or design constraint that prevents incorrect actions
2. Which environmental law regulates the manufacture, importation, processing, and distribution of chemical substances in the U.S.? → TSCA (Toxic Substances Control Act)
3. Which hazard identification method uses structured 'What-If' questions to systematically evaluate potential process deviations? → What-If Analysis
4. Under OSHA 29 CFR 1910.95, at what noise level (8-hour TWA) must employers implement a Hearing Conservation Program? → 85 dBA
5. Which safety metric is calculated as (number of recordable incidents × 200,000) ÷ total hours worked? → Total Recordable Incident Rate (TRIR)
6. Which of the following palettes of colors is used to mark hazardous materials according to NFPA 704? → Yellow, blue, red, white
7. Materials shouldn't be kept any closer to the ceiling than 18 inches in an office setting. What does this rule aim to achieve? → This allows sprinkles to reach all combustible materials
8. What is the primary function of a fire watch? → To monitor for fires during and after hot work operations
9. In a risk assessment, 'inherent risk' (also called 'gross risk') refers to: → The risk level before any controls or safeguards are applied to the hazard
10. A shipping paper for hazardous products shows that Packing Group II applies to the material being shipped. How dangerous is this stuff, exactly? → Moderate danger
11. Which ergonomic assessment tool is designed specifically for upper-limb posture analysis and scores body segments on a scale of 1–7? → RULA (Rapid Upper Limb Assessment)
12. A worker is exposed to Substance A at 40 ppm (TLV 50 ppm) and Substance B at 20 ppm (TLV 25 ppm). What is the combined exposure index? → 1.40
13. What is the OSHA Permissible Exposure Limit (PEL) for silica dust (respirable crystalline silica)? → 0.05 mg/m³ as an 8-hour TWA
14. Which qualitative risk assessment technique uses a visual diagram showing causes on one side and consequences on the other side of a 'tie'? → Bow-Tie Diagram
15. What does a Tier II report under EPCRA Section 312 require facilities to disclose? → Inventory of hazardous chemicals stored on-site above threshold quantities
16. Which waste code designation numbers should a waste storage container with sulfuric acid from used batteries have? → D-002
17. What does a Lifting Index (LI) greater than 1.0 indicate when using the NIOSH Lifting Equation? → The task poses an increased risk of low back injury for some workers
18. What is the maximum storage quantity that classifies a facility as a 'Very Small Quantity Generator' (VSQG) of hazardous waste under EPA regulations? → Less than 100 kg per month
19. What does ANSI/ASSP Z10 address in the context of safety management? → Occupational Health and Safety Management System (OHSMS) requirements
20. According to the hierarchy of controls, which control method is considered most effective for reducing hazards? → Elimination of the hazard
21. Which chemical fire suppression agent is most effective for Class K (kitchen/cooking oil) fires? → Wet chemical (potassium-based)
22. Which of the following best describes data gathered from two distinct variables? → Bivariate data
23. What is the recommended maximum sustained force for a pushing or pulling task to stay within acceptable ergonomic limits for most workers? → 50 lbs initial/35 lbs sustained
24. In ergonomic risk assessment, what does the Strain Index (SI) specifically evaluate? → Distal upper extremity disorders associated with hand-intensive jobs
25. Which NFPA standard covers the installation of sprinkler systems in occupancies? → NFPA 13
26. Which of the following illustrated tools most closely resembles a bar graph? → A histogram
27. In environmental compliance, what is a 'de minimis' discharge? → A small release so minor it is exempt from regulatory reporting thresholds

30. What is the primary difference between a TLV-TWA and a TLV-Ceiling (TLV-C)? → TLV-TWA is an average over an 8-hour shift; TLV-C must never be exceeded at any time
