Learning objectives: Present the ways that spilled or released hazardous materials are harmful to people and the environment. Present the basic clues to HAZMAT recognition and identification. Discuss the types of occupancies where hazardous materials may be stored or used. Show some typical containers that are used for hazardous materials.
For instance: Nerve poisons attack the central nervous system, shutting it down causing such important functions such as circulation and respiration to stop.
Corrosive examples: Acids such as hydrochloric acid or sulfuric acid, or bases, such as caustic potash or potassium hydroxide.
Asphyxiants include such things as inert gases that displace oxygen in the air and carbon dioxide that starves the blood of oxygen inside the body.
Examples: anthrax bacteria, bloodborne pathogens.
Sometimes the alarm will come in with a citizen reporting a “strong smell” as a description of the situation. Be aware.
For instance—fertilizers and fuel. Both are used in farm production. But if they mix and become involved in a fire this deadly combination is a bomb waiting to explode. Pesticides and herbicides—also found on most farms—present a potential life hazard to responders, the public, and animals.
Cylinders under pressure are also a potential problem.
