OSHA 30 Hour Construction Program Practice Test

Why are organic peroxides considered hazardous?

1. They are toxic to skin

2. They act as fire and explosion hazards

3. They release harmful gases

4. They are corrosive to metals

The correct answer is: They act as fire and explosion hazards

Organic peroxides are considered hazardous primarily because they act as fire and explosion hazards. This characteristic is due to their chemical structure, which contains a peroxide group that can undergo decomposition, often exothermically. When decomposed, organic peroxides can release large amounts of energy, leading to uncontrolled reactions that may result in fires or explosions. In addition to their reactivity, organic peroxides can also be sensitive to heat, shock, and friction, which increases the risk of ignition or explosion when they are not handled or stored properly. Therefore, understanding their potential as fire and explosion hazards is crucial for ensuring safe handling and workplace practices in environments where these materials are present. This awareness helps to implement appropriate safety measures and regulations to minimize the risks associated with organic peroxides.
