- Biological hazards: Viruses, bacteria, fungi in healthcare or laboratory settings
- Ergonomic hazards: Repetitive motions, awkward postures, heavy lifting tasks
- Safety hazards: Moving machinery parts, electrical systems, fall risks
Evaluation of Workplace Conditions
The evaluation phase involves quantitative and qualitative assessment techniques to measure exposure levels:
| Assessment Type | Tools Used | Measurement Parameters |
|---|---|---|
| Air Quality | Direct-reading instruments | Particulate matter, gases |
| Noise | Sound level meters | Decibels (dBA) |
| Radiation | Dosimeters | Millisieverts (mSv) |
| Chemical Exposure | Personal sampling pumps | Parts per million (ppm) |
| Heat Stress | WBGT meters | Temperature, humidity |
- Engineering Controls: Ventilation systems, noise enclosures, machine guards
- Administrative Controls: Work rotation schedules, safety procedures, training programs
- Personal Protective Equipment: Respirators, hearing protection, protective clothing
- Workplace Modifications: Ergonomic workstations, improved lighting systems, safety signage
- Monitoring Systems: Real-time exposure alerts, automated shutdown mechanisms
