HAZMAT RC

The process of controlling the flow of a HAZMAT spill and capturing it at some specific location.

The act of stopping the further release of a materal from it's container.

Those measures used to contain and/or confine a material.

Absorption is a physical and/or chemical event occurring during contact between materials that have an attraction for each other.

Prevents air and flammable vapors from combining.

Intervenes between the fuel and the fire.

Lowers the temp of the fuel and adjacent surfaces.

Prevents the release of vapors.

Are designed only for hydrocarbon fires and can be stored at temperatures from 20 to 120 degrees.

Designed for use only on hydrocarbon fires and can be stored at temperatures from 20 120 degrees.

The volume of finished foam that results from a unit volume of foam solution.

The time it takes 1/4 of the total liquid to drain from the foam.

Is the action taken to reduce the emmision of vapors at a HAZMAT spill.

Is the action taken to direct or influence the course of airborne hazardous materials.

The application of water to a water soluble material to reduce it's hazard. However, dilution of liquid materials has few practical applications at a hazmat incident.

Those measures used to contain and/or confine a material.

Is the percentage of gas or vapor concentration in the air that will burn if ignited.

The weight of a substance compared to an equal volume of H20 at a given temperature.

Compares the density of gas to the density of air.

Materials that ignite when they contact each other.

Elements that react and ignite on contact with air.

Any material that is a gas at 68 degrees or less at normal atmospheric pressure.

Any gas poisonous by inhalation, and is a gas at 68 degrees or less, and has a boiling point of 68 degrees or less at normal atmospheric pressure, and that is toxic to humans.

Material that, by contact with water, may become spontaneously flammable or can give off flammable or toxic gas at a rate of 1 liter per KG of material per hour.

Any material having the specific gravity greater than 0.002 microcuries per gram.

This type of railcar is a large, nonpressure tank that is heavily insulated with a vacuum pulled on the space between the inner and outer shells. This tank may have the capacity of 15,000 or 30,000 gallons.

The First Responder is not expected to know how to operate monitoring instruments and interpret readings. However, the First Responder must know where to obtain this equipment and how to contact the technicians who are required to operate it.

Is the operational goal of the incident.

a single occurrence.

A long-term occurrence.

Is a gas that at the charging pressure it is partially liquid at 70 degrees.

A gas that turns into a liquid at or below -130 degrees.

Asphyxiants...effect oxygenation of the body and generally lead to suffocation.

Simple Asphyxiants generally insert gasses that displace 02. These are Nitrogen, Carbon Dioxide, etc

Chemical Asphixants prohibit the body from using 02.

Mutagens cause changes in the genetic system.

Teratogens cause congenital malformations

Inhalation is the process of taking in materials by breathing through the nose or mouth.

Ingestion is taking in materials through the mouth by means other than inhalation.

Injection is taking in materials through a puncture or stick with a needle.

Absorption is taking in materials through the skin or eyes.

The minimum temperature at which a liquid gives off sufficient vapors to form an ignitable mixture with air near its surface.

The minimum temperature to which the fuel in the air must be heated to initate self-sustained combustion.
