ERG
What section in the ERG do we use to identify a general overview for procedures needed for the identified chemicals?
what is the Orange or Guide Section
What is the most Common Complex Ashpyxiant?
What is Carbon Monoxide or CO
The _________ is done by spraying foam onto a backing and letting it roll down onto the fire/spill?
What is the Bank Down technique
A vapor density greater than 1 means a gas or vapor will generally do what?
what is Sink and collect in low-lying areas because it is heavier than air.
This chemical process occurs when heat causes a fuel to decompose into flammable gases before actual ignition occurs.
What is pyrolysis?
What section gives us the correct detailed distance to stay away from a chemical?
What is the Green Section
What is A simple Asphyxiant
These three factors describe the ideal positioning of responding units at a hazardous materials release.
What are uphill, upwind, and upstream?
What are the four components of the fire tetrahedron?
Fuel, oxygen, heat, and the chemical chain reaction.
A warehouse fire has self-vented through the roof. Interior crews report high heat but limited visible flame. Thermal imaging shows significant heat above suspended ceilings. The building contains lightweight steel bar-joist construction and has been burning unchecked for 25 minutes.
Based on risk-versus-gain principles, this strategic shift should be strongly considered.
What is transitioning from an offensive strategy to a defensive strategy?
Ehtyl Acetate has what ID and Guide numbers?
What is 1173 and 129
The Primary hazard to a responder when rescuing victims in a building where non-flammable class 2 product is leaking.
What is Inhalation of Chemicals
This hazardous materials control method involves covering a spill with a material designed to soak up and hold the product.
What is absorption?
What stage of fire development is characterized by all combustible surfaces in a compartment reaching ignition temperature?
What is Flashover
This hazardous materials reaction occurs when a chemical's molecules rapidly join together to form larger chains, often generating significant heat and pressure that can lead to container failure.
What is polymerization?
According to NFPA 704, what are the 4 colors and what do they represent?
What is red - Flammable hazards, Blue - Health hazard, Yellow - instability hazard, White - special hazards
A mixture below its _____ is "too lean" to burn. A mixture above its_____ is "too rich" to burn.
What is LEL/LFL, UEL/UFL
What isolation zone is established immediately around a hazardous materials release to prevent entry by unauthorized personnel?
what is the hot zone
This building-construction type contains noncombustible structural components but does not provide the fire-resistance ratings required of fire-resistive construction.
What is Type II construction?
This common hazard accompanies runaway polymerization as reaction rates increase and more heat is generated, typically seen in batteries
What is thermal runaway?
What is Hydrogen Cyanide solution in alcohol, and 1.2 miles or 1.9 km
What are the 4 types of Radiation, and what can they penetrate?
Alpha - through clothes, Beta - through paper, Gamma - through Human Tissue, Neutron - through everything
At the Operations level, firefighters may perform this defensive control tactic to contain a hazardous liquid spill.
What is diking, damming, diverting, or retention?
This type of collapse occurs when a wall falls outward and the debris scatters approximately the height of the wall away from the structure.
What is a curtain-fall collapse?
A fire is burning in a modern, tightly constructed residence. Interior temperatures continue increasing despite no significant fire growth. Crews vent the roof and simultaneously open the front door. Within seconds, fire rapidly intensifies and spreads through previously uninvolved areas. Firefighters did not create the fire, but they directly caused the increase in heat release rate through this fire dynamics principle.
What is ventilation-limited fire behavior (or ventilation-induced fire growth)?
