McDOWELL COUNTY HAZARDOUS MATERIALS EMERGENCY PLAN
APPENDIX 11 TO HMEP
GLOSSARY
Accident Site
The location of an unexpected occurrence, failure, and/or loss (either at a
facility or along a transportation route) resulting in a release of hazardous
materials.
Acute Severe, but of short duration. Acute health
effects are those that occur immediately after exposure to hazardous chemicals.
Acutely Toxic Chemicals Chemicals that can cause
severe short and long term health effects after a single, brief exposure (short
duration). These chemicals, when ingested, inhaled or absorbed through the
skin, can cause damage to living tissue, impairment of the central nervous
system, severe illness, or, in extreme cases, death.
Aerosol A material that is dispensed from its container
as a mist, spray, or foam by a propellant under pressure; a liquid substance
suspended in air.
Airborne Release Release of any chemical
into the air.
Aquifer An underground rock formation composed of
materials such as sand, soil, or gravel that can store and supply ground water
to wells and springs. Aquifers are usually found within a thousand feet of the
earths surface.
Blasting Agent A material designed for blast.
Boiling Point Means the boiling point
of a liquid at a pressure of 14.7 pounds per square inch absolute (p.s.i.a).
Catastrophic Release Means a major
uncontrolled emission, fire, or explosion, involving one or more highly
hazardous chemicals, that presents serious danger to the population.
Chemnet A mutual aid network of chemical shippers and
contractors. Chemnet has more than 50 participating companies with emergency
teams, 23 subscribers (who receive services during an incident from a
participant and then reimburse response and cleanup costs), and several
emergency response contractors. Chemnet is activated when a member shipper
cannot respond promptly to an incident involving that companys product(s) that
requires the presence of a chemical expert. If a member of the company cannot go
to the scene of the incident, the shipper will authorize a Chemnet contracted
emergency response company to go. Chemnet provides communications for the
network, with the shipper receiving notification and details about the incident
from the chemnet communicator.
Chemical Transportation Emergency Center (CHEMTREC) A program providing
information and/or assistance to emergency responders. Chemtrec contacts the
shipper or producer of the material for more detailed information, including
on-scene assistance when feasible. CHEMTREC can be reached 24 hours a day by
calling 1-800-424-9300.
Chronic Of long duration or having frequent recurrence.
Chronic health effects are those that become apparent or continue for some time
after exposure to hazardous materials.
Color The color of the material
under normal conditions.
Combustible Liquid Any liquid having a
flashpoint at or above 100°F and below 200°F.
Command Post Facility located at a safe distance upwind
from an accident site where the on-scene coordinator, responders, and technical
representatives can make response decisions, deploy manpower and equipment,
maintain liaison with the media, and handle communications.
Compressed Gas A gas or mixture of gases
having in a container, an absolute pressure exceeding 40 psi at 70Ί F (21.1ΊC)
or a gas or mixture of gases having in a container, an absolute pressure
exceeding 104 psi at 130Ί F (54.4 ΊC) regardless of the pressure at 70Ί F.
Corrosive Material Any liquid or solid that
causes visible destruction or irreversible damage to human skin tissue. Also,
it may be a liquid that has a severe corrosion rate on steel.
Decontamination The removal of hazardous
substances from a person to the extent necessary to preclude the occurrence of
foreseeable adverse health affects.
Emergency A situation created by an accidental release or
spill of hazardous materials which poses a threat to the safety of workers,
residents, the environment, or property.
Emergency Alert System (EAS) A system for informing
the public about the nature of a hazardous materials incident and what safety
steps they should take.
Emergency Operations Center A facility where
municipal, county, state, federal, and private entities meet during an
emergency situation to gather information, make decisions, and direct and/or
coordinate necessary actions to bring the emergency to a close. Generally, the
facility is centrally located, and has appropriate communications available for
a totally coordinated effort.
Emergency Public Information Information released to
the public by county, state, and federal agencies concerning the emergency at
hand and how it can affect public health and the environment.
Etiologic Agent An etiologic agent
means a living micro-organism (or its toxin) that causes (or may cause) human
disease.
Explosives Class A Possessing, detonating,
or otherwise maximum hazard, such as dynamite, nitroglycerin, picric acid, lead
azide, black powder, blasting caps, and detonating primers.
Explosives Class B Possessing flammable
hazard, such as propellant explosives, photographic flash powders, and some
special fireworks.

manufactured articles that contain Class A or Class B explosives, or both, as
components but in restricted quantities.
Exposure Means that a person is
subjected to a chemical that is a physical or health hazard, and includes
potential exposure.
Extremely Hazardous Substances A list of chemicals
identified by EPA on the basis of toxicity, and listed under Title III of SARA.
Flammable Liquid Any liquid having a flash
point below 100°F.
Flammable Solid Any solid material (other
than an explosive) that is liable to cause fires through friction or retained
heat from manufacturing or processing. It can be ignited readily and burns so
vigorously and persistently as to create a serious transportation hazard.
Included in this class are spontaneously combustible and water reactive
materials.
Flash Point The minimum temperature at which a
flammable vapor of a substance (in contact with a spark or flame) will ignite.
Hazard Any situation that has the potential for causing
damage to life, property, and/or the environment.
Hazard Analysis The procedure for
identifying potential sources of a hazardous materials release, determining the
vulnerability of an area to a hazardous materials release, and comparing
hazards to determine risks to a community.
Hazardous Chemical Any chemical that is a
physical hazard or a health hazard.
Hazardous Material Any substance or material
in a quantity or form which may be harmful to humans, animals, crops, water
systems, or other elements of the environment if accidentally released.
Hazardous materials include: explosives, gases (compressed, liquefied, or
dissolved), flammable and combustible liquids, flammable solids or substances,
oxidizing substances, poisonous and infectious substances, radioactive
materials, and corrosives.
Hazmat Response Team Means an organized group
of persons who are expected to perform work to handle and control actual or
potential leaks or spills of hazardous substances requiring possible close
approach to the substance. The team performs responses to releases or potential
releases of hazardous substances for the purpose of control or stabilization of
the incident.

within a common organizational structure, with responsibility for management of
assigned resources, to effectively accomplish stated objectives at the scene of
an incident.
Immediately Dangerous to Life and Health A concentration that
represents a maximum level from which one could escape within 30 minutes
without any escape-impairing symptoms or any irreversible health effects.
Irritating Material A liquid or solid
substance that, upon contact with fire or air, gives off dangerous or intensely
irritating fumes.
Joint Public Information Center A single facility from
which multi-organizational emergency public information can be coordinated and
disseminated.
Lethal Concentration Low The lowest concentration
of a chemical at which some test animals died following inhalation exposure.
Lethal Dose Low The lowest dose of a
chemical at which some test animals died following exposure.
Materials Safety Data Sheet A compilation of
information required under the OSHA Hazard Communication Standard on the
identity of hazardous chemicals, health and physical hazards, exposure limits,
and precautions. Section 311 of Title III of SARA requires facilities to submit
MSDSs under certain conditions.
Median Lethal Concentration Concentration level at
which 50% of the test animals died when exposed by inhalation for a specified
time period.
Median Lethal Dose The calculated dose at
which a material kills 50% of a group of test animals within a specified time.
Dose is generally given in milligrams per kilogram of body weight of the test
animal.
National Warning System The federal portion of
the Civil Defense Warning System used for dissemination of warning and other
information from the warning centers or regions to warning points in each
state.
National Response Center Serves as the
notification center for pollution incidents in US waters. It is located at the
US Coast Guard Headquarters in Washington, D.C. and is staffed by Coast Guard
personnel. The toll free number (800-424-8802) can be reached 24 hours a day, 7
days a week for reporting of actual or potential pollution incidents. The NRC
relays reports to appropriate regional authorities for response actions. Spills
can be reported to this center in stead of contacting regional Coast Guard or
EPA personnel.
National Response Team A team consisting of
representatives of 14 federal government agencies. The team is the principal
organization for implementing the National Contingency Plan (NCP). When the NRT
is not activate for a response action, it serves as a standing committee to
develop and maintain preparedness, to evaluate methods of responding to
discharges or releases, and to recommend needed changes in the response
organization, and to recommend revisions to the NCP.
On Scene Coordinator The Federal official
pre-designated by EPA or the USCG to coordinate and direct Federal discharge
removal efforts under Regional Contingency Plans at the scene of an oil or
hazardous substance discharge. Local personnel are subject to the direction and
control of and must clear actions with, the OSC.
Other Regulated Materials Any material that may
pose an unreasonable threat to health and safety or property when transported
in commerce, and does not meet any of the definitions of the other hazard
classes specified in this appendix.
Oxidizer Means a chemical other than a blasting agent or
explosive, that initiates or promotes combustion in other materials, thereby
causing fire either of itself or through the release of oxygen or other gases.
Physical Hazard Means a chemical for
which there is scientifically valid evidence that it is a combustible liquid, a
compressed gas, explosive, flammable, an organic peroxide, an oxidizer,
phyrophoric, unstable (reactive) or water-reactive.
Plume Effluent cloud resulting from a continuous source
release.
Radioactive Material Any material, or
combination of materials, that spontaneously gives off ionizing radiation. It
has a specific activity greater than 0.002 microcuries per gram.
Radius of the Vulnerable Zone The maximum distance from
the point of release of a hazardous substance at which the airborne
concentration could reach the level of concern under specified weather
conditions.
Remedial Action An immediate action taken
over the short-term to address a release or threatened release of hazardous
substances.
Reportable Quantity The quantity of a
hazardous substance that triggers reporting under CERCLA; if a substance is
released in a quantity that exceeds its RQ, the release must be reported to the
National Response Center (NRC), as well as to the State Emergency Response
Commission (SERC) and the community emergency coordinator for areas likely to
be affected by the release.
Response The efforts to minimize the risks created in an
emergency by protecting the people, environment, and property, and the efforts
to return the scene to normal pre-emergency conditions.
Risk A measure of the probability that damage to life,
property, and/or the environment will occur if a hazard manifests itself, this
measure includes the severity of anticipated consequences to a population.
Shelter A facility used to protect, house, and supply the
essential needs of designated individuals during the period of an emergency. A
shelter may or may not be specifically constructed for such use, depending on
the type of emergency and the specific programmatic requirements.
Shipment The shipment is the
freight being transported, which includes the hazardous material contents and
the containment system (box, tank truck, fitting, valves, lids, labels, etc.)
described in the shipping documents. Transportation emergencies involve
hazardous materials shipments, not just hazardous materials.
Special Population Groups of people that may
be more susceptible than the general population (due to preexisting health
conditions or age) to the toxic effects of an accidental release.
Storage Methods of keeping raw materials, finished goods,
or products while awaiting use, shipment, or consumption.
Threshold Limit Value-Time Weighted Average Time-weighted average
concentration for a normal 8-hour work day and a 40-hour work week, to which
nearly all workers may be repeatedly exposed, day-to-day, without adverse
effect.
Threshold Limit Value-Short Term Exposure Limit A concentration to which
workers can be exposed continuously for short periods of time without suffering
from (1) irritation, (2) chronic or irreversible tissue damage, (3) narcosis of
a sufficient degree to increase the likelihood of accidental injury, impair
self-rescue, or materially reduce work efficiency, provided the daily TLV-TWA
is not exercised.
Toxic Cloud Airborne mass of gases, vapors, fumes, or
aerosols of toxic materials.
Toxicity The ability of a substance to cause damage to
living tissue, impairment of the central nervous system, severe illness, or
death when ingested, inhaled, or absorbed by the skin.
Toxicology The study of the adverse effects of
chemical agents on biological systems.
