Chemical and physical properties are the characteristics of a substance that are measurable, such as vapor density, flammability, corrosivity, and water reactivity.

Yep

Chiefly, irritants cause pain and a burning sensation in exposed skin, eyes, and mucous membranes. The onset of symptoms occurs within seconds after contact and lasts several minutes to several hours, usually with no lasting effects. Irritants can be dispersed from canisters, hand-held sprayers, and grenades

Yep

Fire departments must follow both the OSHA and the NFPA requirements for hazardous materials response. NFPA 472 clearly states, "The operations level responder shall receive additional training to meet applicable governmental occupational health and safety regulations"

In such cases, fire fighters might become contaminated and subsequently handle tools and equipment, grasp door handles, or touch other responders, thereby spreading the contamination. The possibility of spreading contamination brings up a point that all fire fighters should understand: The cleaner fire fighters stay during the response, the less decontamination they will have to do later.

Yep

Most fire fighters have not been trained on the fire points of handling incidents involving radioactive materials and, therefore, have many misconceptions about radiation. Oddly enough, in many ways radiation incidents are some of the easiest hazardous materials events to deal with-assuming that fire fighters have the right training and the right equipment to respond to them.

Regarding HA HA MICEN Although this list is not all inclusive, most materials not on this list are heavier than air (i.e., vapor density > 1). If you encounter a leaking propane cylinder, for example, just think HA HA MICEN. Propane is not that list, so by deafult, you can assume that propane is heavier than air.

Yep

Regarding Irritants Exposed patients can be decontaminated with clean water, and the residual effects of the exposure are rarely significant. It is important for fire fighters to know which specific agents are used by local law enforcement agencies and any specific decontamination techniques recommend for use with those agents.

Yep

SERCs and LEPCs often work together closely to help a community prepare to deal with hazardous materials incidents.

Yep

The hazardous materials officer is trained to act as a branch director or group supervisor for the hazardous materials component of the incident.

Yep
