OPM538-CH4

2. – Work overload, role conflict, or lack of control. (Leads to burnout and reduced productivity.)
4. – Systematic study of workplace hazards to protect worker health and the environment
5. – Pathogens in labs, hospitals, or farms
6. – OSHA’s 85 dB 8-hour exposure threshold
9. – Emergency cutoffs, alarms, and ergonomic tools
13. Data Sheets (SDS) – Documents detailing chemical hazards
14. – Noise, extreme temperatures, radiation, and pressure risks. (Can lead to hearing loss or heat stress.)
15. – Eliminating hazards or using PPE to reduce exposure
16. – Choosing safer, less polluting technologies
18. – Bacteria, viruses, and fungi in healthcare or agriculture. (No safe exposure threshold.)
19. – Color codes, sounds, and labels for hazard alerts
20. – Identifying risks like chemicals, noise, or ergonomic strain

1. – Asthma, cancer, or hearing loss linked to workplace exposures.
3. – Areas with limited entry/exit and air hazards
7. – Caused by high demands, low control, or poor feedback
8. – Last line of defense (masks, gloves, earplugs)
10. Controls – Machine guards or ventilation systems
11. – Removing hazards entirely (e.g., automating a risky task)
12. – Poor posture, repetitive strain, or improper workstation design. (Causes musculoskeletal disorders.)
17. – Mists, vapors, gases, and dusts causing immediate or long-term health effects. (Routes: inhalation, skin absorption, ingestion.)
