What is a Hazardous Technician Responder?
NFPA 472:7.1.1 the hazardous materials technician shall be that person who responds
to hazardous materials of WMD incidents using a risk-based response process by which
they analyze a problem involving hazardous materials/WMD, selects applicable
decontamination procedures, and controls a release using specialized protective
clothing and control equipment.
Prerequisites
Must be Awareness and Ops Certified
May receive additional info from:
OSHA
Additional competencies that is specific to the response mission, expected tasks, and
equipment and training as determined by AHJ
Goal
The goal of the competencies at this level shall be to provide the hazardous materials
technician with the
knowledge and skills to perform the tasks in safely.
Analyze
Survey a hazmat/WMD incident
Collect a hazard & response information
Describe the type & extent of damage to containers
Predict the behavior of released material and their contents
Estimate the size of the endangered area
Plan
,Describe response objectives
Describe the potential response options
Select personal protective equipment
Select a technical decontamination process
Develop an Incident Action Plan
Implement
Perform the duties of an assigned hazardous materials branch or group position
Don, work in, and doff personal protective clothing
Perform control functions identified in the Incident Action Plan
Evaluate
Evaluate the effectiveness of the control functions
Evaluate the effectiveness of the decontamination process
Terminate
Assist in the incident debriefing
Assist in the incident critique
Provide reports and documentation of the incident
Acid
any substance whose aqueous solutions are characterized by a sour taste, the ability to
turn blue litmus red, and the ability to react with bases and certain metals to form salts.
pH less than 7 in its standard state.
Caustic
capable of burning, corroding, dissolving, or eating away by chemical action. pH greater
than 7 in its standard state.
Air Reactivity
Materials that can react or ignite if they are exposed to air.
Auto-refrigeration-
A phenomenon that occurs during the rapid release (boiling) of a liquefied gas that
causes it to temporarily remain in a liquid state through rapid cooling.
Risk: False assumption of product elimination until the product resumes boiling and
subsequent release.
Biological agents -
,Biological Agents include bacteria, viruses, fungi, other microorganisms and their
associated toxins. Many microbes reproduce rapidly and require minimal resources for
survival; therefore, they are a potential danger in a wide variety of occupational settings.
Biological toxins -
Toxins can be small molecules, peptides, or proteins that are capable of causing
disease on contact with or absorption by body tissues.
Risk: Affects human health in a variety of ways ranging from allergic reactions to death.
Blood Agents
A chemical compound, including the cyanide group, which affects bodily functions by
preventing the normal utilization of oxygen by body tissues. The term "blood agent" is a
misnomer, however, because these agents do not actually affect the blood in any way.
Boiling Point
Temperature at which the transition from a liquid to a gas state occurs. At this
temperature, the vapor pressure of a liquid equals the surrounding atmospheric
pressure so that the liquid rapidly becomes a vapor
Catalyst -
A substance that initiates or accelerates a chemical reaction without itself being
affected.
Chemical Change
Changes that take place on the molecular level. A chemical change produces a new
substance.
Chemical Interactions
Caused when two or more chemicals, or the chemical and its container are
incompatible.
Compound, mixture
Separate elements that bond together to form compound mixture, they have a tendency
to break down into their component parts, sometimes in an explosive manner.
Concentration
When dealing with corrosives, the amount of acid or base is compared to the amount of
water present.
Critical Temperature
, The minimum temperature at which a gas can be liquefied no matter how much
pressure is applied. A gas cannot be liquefied above its critical temperature.
Critical Pressure
The pressure that must be applied to bring a gas to its liquid state.
Dissociation
The separation of a substance into two or more simpler substances, or of a molecule
into atoms or ions, by the action of heat or a chemical process. Dissociation is usually
reversible.
Corrosive (acids and bases/alkaline)
a measure of a substance's tendency to deteriorate in the presence of another
substance or in a particular environment.
Dose
The concentration or amount of material to which the body is exposed over a specific
time period.
Dose Response
The biological reaction caused by the dose in the body. The degree of harm is directly
related to the dose (time and amount) and its impact on bodily functions.
Expansion Ratio
The amount of gas produced by a given volume of liquid at a given temperature.
Flash Point
The minimum temperature at which a material gives off vapor in sufficient concentration
to form an ignitable mixture with air and will not continue to burn.
Fire Point
The temperature at which enough vapors are given off to support continuous burning.
Flammable (explosive) range -
The difference between the upper and lower flammable limits.
Lower explosive limit (LEL)
is the minimum concentration of vapor to air below which a flame will not propagate in
the presence of an ignition source. Also known as "Too lean to burn"
Upper explosive limit (UEL)
