What are the hazards in working in confined spaces?

1. Lack of oxygen: Confined spaces may have limited ventilation, leading to a decrease in oxygen levels, which can result in asphyxiation.

2. Toxic gases and fumes: Confined spaces may contain hazardous gases or fumes that can be harmful or even fatal if inhaled.

3. Flammable substances: Confined spaces may contain flammable substances that can ignite and cause fires or explosions.

4. Engulfment: Workers in confined spaces may be at risk of being engulfed by materials such as grain, sand, or water, leading to suffocation.

5. Physical hazards: Confined spaces may have limited space to move around, leading to the risk of falls, trips, or getting trapped.

6. Heat stress: Confined spaces may have high temperatures, leading to heat stress and dehydration.

7. Biological hazards: Confined spaces may harbor bacteria, viruses, or other pathogens that can cause illness or infection.

8. Noise: Confined spaces may amplify noise levels, leading to hearing damage over time.

9. Psychological hazards: Working in confined spaces can be stressful and claustrophobic, leading to anxiety or panic attacks.

Atmospheric hazards:
