Transcript of Copy of HAZMAT MFD
What is a Hazardous Material?
- Any Material that possesses and unreasonable risk to the health and safety of persons and/or the environment if it is not properly controlled during handling, storage, manufacture, processing, packaging, use, disposal, or transportation.
- "Harmful Stuff that is not contained or isolated."
RULE OF THUMB
DEFENSIVE, DEFENSIVE, DEFENSIVE!
- FIRST RESPONDER HAZMAT IS DEFENSIVE.
- SAFTEY (PERSONAL AND PERSONNEL)
- ISOLATE AND DENY ENTRY
- NOTIFY APPROPRIATE AGENCY(s)
- ESTABLISH COMMAND
- IDENTIFICATION AND HAZARD ASSESSMENT
- ACTION PLANNING (DEFENSIVE)
- CONTAINMENT AND CONTROL
- PROTECTIVE ACTIONS
IDENTIFY & HAZARD ASSESSMENT
CONTAINMENT AND CONTROL
USE OF ONE OF THREE STRATEGIES
-let incident run its course,
-will have minimal effects
-more harm may be done if action taken *not worth risk
-Focus on confinement
- OFFENSIVE (TECHNICIAN)
-Focus on controlling, slowing, or stopping source.
COMMAND & MANAGEMENT
INSURE THAT INCOMING UNITS ARE ADVISED OF BEST APPROACH.
RULE OF THUMB
- Deny entry (protect yourself and crew)
- Use ERG, physical state and product
- still contained? How much?
- Insure proper distance.
Request for proper response
- Media (for public)
- Hospitals (if MCI)
- Establish command
- Initial actions
KEEP YOUR DISTANCE!
- NFPA 704: The standard system for the identification of the hazards of materials in an emergency response.
- SCOPE: This standard shall address the health, flammability, instability, and related hazards that are presented by short-term, acute exposure to a material under conditions of fire, spill, or similar emergencies
TOOLS- shipping papers, MSDS, ERG, Training.
- goal? Be Realistic
RISK vs. GAIN?
- take into consideration resources
no respiratory protection required
NOT ADEQUATE FOR FIRST RESPONDERS
minimal skin protection
THE US EPA established following levels
- recognized by NIOSH and OSHA
resp. < SCBA
Gloves and boots subject to change for substance handled.
same as level C accept increase in respiratory protection
Levels of Incident
- level I incident - least serious
seen often with t.c.
small amount of gasoline
domestic natural gas leak
broken containers of "consumer commodity"
i.e. paint, thinners, bleach, ect.
- level II incident - moderate
beyond the capabilities of the first responders on scene.
HAZMAT TEAM NEEDED.
- proper PPE needed
- dikes or plugging/patching
- possible BLEVE threat
- level III incident - most serious
need for state/federal/private industry response needed
- large scale to evacuation
- sophisticated monitoring or sampling needed
- specialized leak and spill control
-keep in mind how to direct incoming resources to the scene.
-routes to hospitals
- define the problem
- design a defense
- direct action plan
**Minimum isolation distance
- Contamination: the transfer of a hazardous material to a person, equipment and the environment in greater than acceptable quantities.
- Secondary Contamination: Contamination of people, the environment or equipment outside the exclusion zone.
- chemical degradation
use of another chemical to change the hazardous chemical
IMPORTANT! insure all victims are decontaminated before leaving scene or at hospital decon site (depending on exposure and amount of victims.)
MFD will not dispose.
private agency or other resource on scene specialized in such disposal and containment measures will be responsible.
DO NOT ATTEMPT!
- EXPOSURE RECORDS
- COST RECOVERY
- FUTURE LITIGATION
- CASE STUDIES
incidents are rare and we can learn from them
Placards & Hazard Classes
Department of Transportation has 9 classifications
- class 1 = explosives
- class 2 = gases
- class 3 = flammable liquids
- class 4 = flammable solids
- class 5 = oxidizers
- class 6 = poisons
- class 7 = radioactive
- class 8 = corrosive
- class 9 = misc. Hazmat
( class 9 can be most hazardous)
Class 1 - Explosives
explosives with mass explosion hazard
explosives with projection hazard
explosives with no significant blast hazard
explosives with mainly a fire hazard
very insensitive explosives with a mass explosion hazard
extremely insensitive explosives
Class 2- Gases
Flashpoint not > than 141 degrees F
3.1 = flashpoint < 0 degrees F
3.2 = flashpoint 0 to < 73 degrees F
3.3 = flahpoint > 73 to < 141 degrees F
Flashpoint = > 140 degrees but < 200 degrees
i.e. magnesium powder
UNSTABLE/ REACTIVE EXPLOSIVES
TOXIC OR POISONOUS
EXCLUDING A SELECT FEW: EXPLOSIVES/INHALATION HAZARD/COMBUSTIBLE-WATER REACTIVE/ORGANIC POROXIDE/RADIOACTIVE
LOADS DO NOT AHVE TO PLACARDED UNLESS THEY HAVE 1,001 LBS OR MORE OF ANY PARTICULAR MATERIAL.
THEREFORE, COMBIND LOADS UNDER 1,000 LBS WILL HAVE THIS PLACARD.
NFPA 704: DEFINES THE COLLOQUIAL "FIRE DIMOND"
Only W/OXY/OX are officially part of the NFPA 704 system
0.5mrem/hr or less
0.5mrem/hr to 50mrem/hr
50.mrem/hr to a max of 200mrem/hr
