Chp2 Flashcards
For first responders, a hazardous materials can be defined as anything that can harm –, –, or the –.
PPE
People
Property
Environment
Whose responsibility is to provide guidelines for the safe storage, transport, and use of a material.
Regulatory agencies
Who gives rise to the terms such as hazardous material, hazardous chemical, hazardous substance, and hazardous waste.
Governmental regulatory
Agencies
What are the five forms of a hazardous material?
Solid Liquid Gas Vapor Mist Dust
— from liquids and — from solids can create potential inhalation and fire hazards, sometimes far from the source of the release.
Vapors
Dusts
- MSDS
- Contacts with a chemical manufacturer shipper
- local, state, and federal regulatory agencies
- medical professionals(especially those from Government health departments
- poison control centers
Can all be used to evaluate what?
hazardous characteristics of a material.
The persons responsible for the release of any material or those who are in possession of the container from which the release originated are usually referred to as the:
Responsible party
Who are the ones who will likely be held responsible if a decision that a material is not hazardous goes bad, not the responsible party..
First responders
An — is a sudden, violent release of mechanical, chemical, or nuclear energy from a confined region.
Explosion
Hazards related to this class include being under pressure, flammable, unstable, toxic, corrosive, and oxidizing agents.
Compressed gases
What is the controlling factor in considering flash point?
The temperature of the liquid itself.
Some — may be water reactive.
Flammable solids
There may even be very violent reactions when they are intimately mixed with ordinary combustible materials.
Oxidizers
Because of — agents ability to provide oxygen when heated their hazard is greatly increased at higher temperatures.
Vs
Oxidizing agents readily decompose to yield oxygen when heated and therefore may:
Oxidizing
React easily with other hazardous materials
A — is any substance that causes injury, illness, or death to living tissue by chemical activity.
Poison
These materials into the body and one of four ways:
Inhalation
Ingestion
Absorption thru the skin, and entry thru a wound
Poisons enter the body and what four ways?
Inhalation
Ingestion
Absorption thru skin or wounds
— involves particles traveling in wavelike motions
IONIZING radiation
Particles collide , removing the electron, thus creating an ion
A — is any material that will attack and destroy by chemical action any living tissue with which it comes in contact
Corrosive
This term means “The category of Hazard” assigned to a hazardous material.
Hazard Class
“Precedence of hazard table” requires that only the primary hazard class to be displayed.
Only in limited circumstances will information on — hazards be displayed.
Subsidiary
These materials are those “which present a hazard during transportation but do not meet the definition of any other hazard class”
(Ex: noxious flight crew member)
Class 9
“OSHA hazard Communication “uses the term—-Which is defined as: “any chemical which is a physical hazard or health hazard”
Hazardous chemical
Therefore, an employer at a fixed facility is not required by the OSHA Hazard Communication Standard to provide a first responder with a —, since he is not an employee of that facility.
MSDS
“OSHA hazardous waste operations and emergency response”
includes training standards for first responders as well as requirements for on-scene emergency operations, and uses the term—.
Hazardous substance
Under the — , owners or operators of facilities that use certain chemicals are required to submit copies of MSDS to local emergency planning committees and fire departments with jurisdiction for the facility.
Emergency planning and community right to know act
Defined exposure limits and research on effects of exposures to chemicals can change how often?
During the course of several years
CFR governing transportation defines gasoline as what when transported in commerce?
Flammable liquid
What regulatory agency governs transportation?
The code of federal regulations
Who assigns hazards classes and their associated class number?
Federal transportation regulations
What hazardous material can destroy living tissue as well as readily decompose and yield oxygen?
Corrosives
OSHA Hazardous Waste Operations and Emergency Response
does what?
- Emergency response ops of haz. “Substances” without regard to the location of the hazard.
- uses the term: hazardous substance
- training standard for first responders
- requirements for on-scene emergency operations
The EPCRA
Does what?
- MSDS to FD’s
- uses the term hazardous chemical BUT adds exceptions to the definition
(There’s like 4 long definition exceptions)
Who determines if a material that is RELEASED from its container has the potential to harm themselves or the community?
First responders
In addition, products that meet multiple definitions for hazardous materials may be regulated only on the basis of what a regulatory agency defined as the:
Highest priority
Whether regulations govern transportation or the workplace, the — used for hazardous materials will influence the FORMAT as well as the AMOUNT of information made available to first responders.
