McDOWELL COUNTY HAZARDOUS MATERIALS EMERGENCY PLAN

APPENDIX 11 TO HMEP

GLOSSARY

 

 

DEFINITIONS

 

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 earth’s 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 company’s 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 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.

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.

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.

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.
