Hazmat

a substance or material capable of posing an unreasonable risk to health , safety, or property when transported in commerce.

Hazard class

is a group of hazardous materials that share dangerous characteristics. Their are 9 hazard classes

Hazardous Substance

any substance designated under the clean water act and comprehensive environmental response compensation and Liability act.CERCLA

Extremely Hazardous Substnances (EHS)

chemicals determined by the EPA to be extremely hazardous to a community during an emergency spill or release as a result of their toxicities and physical chemical properties.

Hazardous Chemicals

any chemical that would be a risk to employees if exposed in the workplace.

First Responder

individuals who are likely to witness or discover a hazardous substance release and who have been trained to initiate an emergency response notification.

Hazardous Materials Technician

individuals who respond to releases or potential releases for the purposes of stopping the release.

Hazard Communication Regulation
(HAZCOM)

requires hazardous materials manufactures and handlers to develop written MSDS.

TIC's & TIMs

toxic industrial chemicals and materials

Agricultural Chemicals

organophosphates, ammonia

Chemical Warfare Agents

nerve agents, vesicants, blister agents, blood agents

Riot Control & Irritants

pepper spray, oleoresin capsicum OC spray.

Biological toxins

ricin, botulinium

Pathogens

disease causin organism
anthrax, plaque, smallpox, bird flu , h1n1

Asphyxiation(Suffocation)

simple, chemical

Container Failure

punctures, abrasions, lacerations

Mechanical Effect

physical trauma from moving material or wave pressure

Radiological Effects

alpha
beta
gamma
neutron
x-ray

Radiation

ionizing energy spontaneously emitted by material or combination of materials.

Radioactive Material

one that spontaneously emits ionizing radiation.

Roentgen

(R)

RAD

radiation absorbed dose

REM

radiation equivalent to man.
applies to all types of radiation
takes into account the energy absorbed(dose) and the biological effect on the body due to the different types of radiation.

Half-Life

the measure of the rate of decay of a radioactive material.

Types of Radiation

ionizing radiation
non-ionizing radiation

Ionizing Radiation

involves particles travailing in a wave like motion.
produced from: ALPHA BETA GAMMA

Non-Ionizing Radiation

made up of waves of energy. non ionizing radiation comes from ultraviolet and infrared energy waves.

Alpha radiation

partials that will travel 3 to 4 inches and will not penetrate the skin.
can be contaminated by
Injection
inhalation
ingestion

Beta Radiation

particles will penetrate the skin and may travel from 3 to 100 feet.
can by contaminated by
inhalation
ingestion
injection
absorption
penetration

Gamma Radiation

gamma radiation is a naturally occurring high energy electromagnetic wave.
high penetrating power and travels at the speed of light.
will penetrate the skin and will cause injure to the internal organs if not shielded.

3 characteristics of an EMERGENCY RESPONSE

We Cannot Smell it
We Cannot Taste it
We Cannot See it

Nerve Agents

SARIN (GB)
SOMAN (GD)
TABUN (GA)
V AGENT (VX)

Blister Agents (VESICANTS)

Mustard
Lewisite

Blood Agents

Hydrogen cyanide
Cyanogen Chloride
Arsine

Choking Agents

Chlorine
Phosgene

Irritants

Chloropicrin
Mace
Tear Gas
Pepper Spray

Viral Agents

smaller than bacteria ... Lives inside individual cells

Bacterial Agents

single celled organisms capable of causing disease in plants, animals , and humans.

Biological Agents

toxic substance of natural origin produced by an animal, plant or microbe.

Routes of Entry or Biological Agents

inhalation
absorption
ingestion
injection

Toxicology

the study of chemical or physical agents which interact with biologic systems to produce a response in organisms.

Toxicity

the relative ability of a substance to cause injury to biologic tissue

Acute Toxicity

ability of a chemical to produce adverse health effects as a result of a short exposure.

Chronic Toxicity

when a chemical produces damage after repeated exposures.. May have long latency intervals, develop slowly or require years of repeated exposure before they are manifested.

Lethal Dose (LD-50)

a calculated dose of a substance which is expected to cause the death of 50% of an entire defined experimental animal population.
Lethal concentration Low (LClo)

Lethal Concentration Fifty (LC50)

a calculated concentration of ta substance in air, exposure to which for a specified length of time is expected to cause the death the death of 50% of an entire defined experimental animal population.

Factors Influencing Toxicity

Route of Exposure
Sex
Age
Synergism, Antagonism, Potentiation
Genetics
Species Variation

Identification Clues

container shapes
markings and colors
placards and labels
shipping papers

Information Provided by Manifest

proper shipping name
hazard class and division
DOT or UN identification number
total quantity
any special hazards
first aid requirements
emergency contact number manufacturer
CHEMTREC or CANUTEC

CHEMTREC or CANUTEC

Number for the hazard info that is being shipped

TLV

Threshold Limit Valve

IDLH

Immediate Dangerous to Life and Health

MSDS

Material Safety Data Sheets

Warnings and Indicators

Shipping manifest
Placards
labels

Interviews

driver, others involved in transportation of materials
witnesses
victims

Communications

Texas Law enforcement telecommunication System (TLETS)
Shipper at point of origin

NIMS

National Incident Management Systems

ICS

Incident Command System

Basic Procedures of safequarding lives at a Hazmat Event.

Initial assessment and response at an incident
Removing citizens from the affected area
Minimizing health hazards for responders

Decontamination concepts

End the exposure
neutralize
Isolate

Hazardous Materials Event

situation in which HAZMAT is or may be released into the environment.

Dose-Response Concept

all substances in the right amount become toxic.

Exposure

the process by with people, animals, and equipment are subjected to or come in contact with a HAZMAT.. the magnitude of exposure depends on the duration and the concentration of the material.

Pipelines

must contain:
operator name
emergency phone #
name of material

SIN

Safety
Isolation
Notification

ERG ( Emergency Response Guide)

basic safety tool for 1st responders to ID HazMat

Objectives of Hazmat

recognize the need for additional resources
gather information regarding the release
identify the HazMat if possible
take appropriate actions to isolate the hazard and deny entry

Modular Design

the incident command system is based on modular design, it allows transition from small to large scale incidents.

Safequarding Lives at ta HazMat incident

Removing citizens from the affected area
limit spread of contamination
establish safe travel routes for public enforce perimeter security.
remain up-hill and up-wind
wait for qualified assistance
remain outside the designated perimeter.

Safequarding Lives at ta HazMat incident

observations
assessment
plan
communicate
respond

Protection level A

selected when the greatest level of skin, respiratory and eye protection is required.

Protection level B

used in situations when the highest level of respiratory protection is require, for example, using SCBA.

Protection level C

used when the type of airborne contaminant and its concentration level are known.

Protection level D

used to afford minimal protection against nuisance contaminants only.
used in atmosphere contains no known hazards.

Overcoat flash suit

may or may not give chemical protection depending on application.

Sources to obtain On-site information

highway-bill of lading
rail-waybill
water- located in the wheelhouse or with the Captain
air-air bill

CERCLA 1980

Comprehensive Environmental Response Compensation and Liability Act.

RCRA 1976

Resource Conservation and Recovery Act.

Working in a Hazmat Incident

use a safe a cautious approach
identify the hazardous material

EPA

substance which due to its concentration, quantity or chemical/physical properties may cause or contribute to an increase mortality & illness

DOT

any substance or material in any form or quantity which poses an unreasonable risk to safety, health and property when transported in commerce.

OSHA

any substance to which exposure results or may result in adverse effects on health or safety of employees or any chemical which is a physical hazard or a health hazard.

Technician

responds and assumes a more aggressive role than the 1st responder.

Specialist

respond w and provide support to hazmat techs

Incident Commander

assumes control over incident scene: has overall management of the incident
