Explain the causes of each of the following types of atmospheric hazards encountered in the marine safety field: 1. Oxygen deficiency 2. Explosion hazards 3. Toxicity hazard
Understand the Problem
The question asks to explain the causes of each of the following types of atmospheric hazards encountered in the marine safety field:
- Oxygen deficiency
- Explosion hazards
- Toxicity hazard
Answer
Oxygen deficiency is caused by oxygen consumption or displacement. Explosion hazards arise from flammable gases or vapors. Toxicity hazards are due to the presence of hazardous substances.
Here are the causes of atmospheric hazards:
- Oxygen deficiency: Can arise from the consumption of oxygen through rust, the presence of hydrocarbon vapors, or the displacement of oxygen by other gases.
- Explosion hazards: Flammable gases, vapors, and mists exceeding 10% of their lower explosive limit (LEL) can lead to explosions.
- Toxicity hazard: Toxic atmospheres occur due to the presence of hazardous substances.
