AHJ Authority Having Jurisdiction
Train EMS to levels of education
ERG
Emergency Response Guidebook
Front is placards and containers/vessels
Back is numbers
Placards
Diamond signs of substances being carried
Labels
Smaller version of of placards placed on four sides of boxes
CHEMTREC
Chemical Transportation Emergency Center operates 24 hour line
MSDS
In depth information about hazardous material and provides basic information about chemical makeup of a substance potential hazards, appropriate first aid and other data
Secondary Containment
Engineered method to control spilled or released product if main containment vessel fails
Night and Day
Night is a longer isolation distance due to humidity and temperature
Intermodal Tanks
Both shipping and storage vessels can be pressurized or nonpressurized substance
Carboys
Glass plastic or steel container that holds 5-15 gallons
MC 306 DOT 406
Carry flammable liquid tanker typically hauls flammable and combustible liquids
MC 307 DOT 407
Carries chemicals flammable liquids, mild corrosives or Posions
Tube Trailors
Carry gases
Dry Bulk Cargo Tanks
Carry fertilizer, seeds and powders
Hot zone
contamination zone
Have to wear right PPE
Warm Zone
Surrounds hot zone
Decontamination corridor located in warm zone
Cold Zone
Perform triage and where paramedics hang out
Level A Ensemble
Provides greatest respiratory and skin protection from exposure t hazardous material with supplied air
Level B Ensemble
When responder needs respiratory protection but the substance does not pose a lethal threat via skin absorption still worn with mask
Level C
Minimal splash protection
Level D
Usually worn in cold zone with minimal protectikn
Primary Contmination
Initial exposure
Secondary Exposure
Exposure from one person to another
Local Effect
Reddening of skin, localized pain, formation of blisters
Systemic Effect
Damage to airway, mental status, heart
Vapor Pressure
Pressure in a sealed container with a liquid
Vapor density
Compares weight of gas to air of a substance
Threshold Limit Value
Maximum concentration of a toxin someone can be exposed to for a 40 hour work week for 30 years
Absorption
Large pads that hazardous materials team carries to soak up liquid and remove it from the patient
Neutrilization
Use of chemical to change hazardous materials into less harmful substances
Disposal
Result of process
CAMEO
Computer Aided Management Of Emergency Operations
Mass decontamination
Douse of large number of patients with copious amounts of water
Decontamination corridor
Controlled area within warm Zone where decontamination takes place
Technical Decontamination
Process used by responders to clean PPE, tools and equipment
Corrosives
Chemicals that include both acids and bases
Solvents
Substances capable of dissolving other substances
Require extensive decontamination
Pesticides
Organophosphate SLUDGEM Salivation Lacrimation Urination Defecation GI activity Emesis Miosis
Asphyxiants
Any gas that displaces oxygen from atmosphere (colorless odorless gases)
Carbon monoxide
Cyanide
IDLH
Immediate danger to life and health
