Exposure and the Body's Response.
The body works very well under everyday events but when the body becomes in contact with certain toxins, the systems of the body can have extreme reactions and possibly lead to death. A Team Member needs to be aware of signs and symptoms that the body has become contaminated. .
Every hazardous material has a standard and guidelines; some standards are Threshold Limit Value (TLV), Permissible Exposure Limit (PEL) and Short Term Exposure Limit (STEL). These standards tell the members how long someone can be in contact with certain chemicals, most are regulated by the American Conference of Governmental Industrial Hygienists and Occupational Safety and Health Administration (OSHA). .
Some responses vary for each system in the body. Carcinogenic, chronic illnesses and death are the most common if exposed for too long. In the heart the electrical conduction system can have disturbances, a decrease in the contacting of the heart and enhanced arteriosclerosis. Even your blood can be effected, the platelet activity decreases, and red blood cells can be destructed. In the gastrointestinal systems the liver can develop cirrhosis and malignant tumors. .
The human body is composed of many different body systems working together. HAZMAT Team members have the potential for exposure to many hazardous materials that could interfere with the body's normal functions or permanently damage certain organ systems.

Personal Protective Equipment.
Emergency responders at a hazardous materials incident must be protected against potential hazards. The purpose of personal protective clothing and equipment (PPE) is to shield or isolate individuals from the chemical, physical and biological hazards that may be encountered during hazardous materials responses.

National security America over its short life time has built up this reputation for being "untouchable". We are so far away from any major threats, and because of this, America has gone to sleep. It used to be that communication amongst countries would take months at a time. Your conversation was instantaneous; you could talk to someone on the other side of the world! If it wasn't for communication, we probably wouldn't have been involved in WW2. ...
