What is the intention of an indirect fire attack?
Indirect attack is a firefighting operation involving the application of extinguishing agents to reduce the buildup of heat released from a fire without applying the agent directly onto the burning fuel (P..
Will a car explode if it catches on fire?
It’s very rare to see a car explode when it catches fire. For a car to blow up, it needs the perfect proportion of oxygen, gas, and fire. Cars run on liquid gas which will typically not explode when set on fire.
Which is an indicator of potential building collapse?
The following collapse indicators include some associated with water usage and other building loads. Excessive water in a building. Water not coming out of a building as fast as it is going in. Water runoff from between bricks.
Does fire use energy?
Fire does use energy as part of its chemical reaction. Heat reacts with the fuel and oxygen and causes the fire to bloom.
When fighting a vehicle fire a piercing nozzle can safely be used to?
When fighting a vehicle fire, a piercing nozzle can safely be used to: extinguish fire under the hood. Which hazard is associated with a hybrid electric vehicle that is on fire?
What causes a car to catch on fire?
Cars catch fire for a number of reasons. Most issues are mechanical or electrical. The most common danger signs that indicate a car may catch fire include oil or fluid leaks, rapid changes in fuel levels or engine temperature, and cracked or loose wiring.
What happens during a transitional attack?
A state of partial fire extinguishment which will allow for fire regrow in a short period of time without additional intervention. … Transitional attack is currently more about attempting to catch up to the interior attack, instead of improved stream usage and gaining a knock down of the fire.
What is a natural cover fire?
Fighting Natural Cover Fires A review of the techniques and factors to be considered when combating grass, brush and forest fires —Photo by John Titchen NATURAL COVER fire fighting, the extinguishment of grass, brush, weeds, lots, forest, trash and dump fires, represents about 25 per cent of the alarms and 50 per cent …
What is a size up in firefighting?
Size-up is defined in most fire service texts as the on-going evaluation of problems confronted within a fire situation. Size-up starts with the receipt of an alarm and continues until the fire is under control. This process is carried out many times and by many different individuals at each fire or emergency event.
What is fireground?
: an area in which fire-fighting operations are carried on.
What happens during a blitz attack?
This is where the Blitz Attack (BA) concept of firefighting comes into play. The BA is an offensive fire attack strategy which involves attacking a fire with as large a volume of water as safely and efficiently as possible to knock down the fire in seconds.
What is an indirect attack?
An indirect attack is defined as the building of impermeable fireline along a pre-determined route, independent of the direction or pattern of simulated fire growth. This line is not meant to contact the active fire front until after line construction is finished.
What is a combination fire attack?
The combination attack is intended to both cool the hot upper layer and apply water to burning fuel (less so to cool compartment linings, although this is accomplished as well). The term “combination” refers to the combination of direct and indirect attack.
What car catches on fire the most?
Some recent recalls and news reports include the following vehicles that are most likely to catch fire:Mitsubishi Outlander Sport: … Mercedes sedans and SUVs made from 2015-2017. … Nissan 2016 and 2017 Murano and Maxima, 2017 Infiniti QX60, and 2017-2018 Pathfinder.More items…•
What part of a ground cover fire spreads the most rapidly and usually does the most damage?
headThe head is the part of a ground cover fire that spreads most rapidly. Usually found opposite the origin in the direction the wind is blowing. The head burns intensely and does the most damage.
Which type of attack is typically used for a small fire in a room?
direct attackA direct attack is a good choice when there are smaller fires or when the heat level of the room is low. This attack is delivered through water application directly on the fire with a narrow fog or straight stream, rather than from above it.
Do fire have cells?
The reason fire is non-living is because it does not have the eight characteristics of life. Also, fire is not made of cells. All living organisms is made of cells. Although fire needs oxygen to burn, this does not mean it is living.
What are the three incident priorities?
Decisions on the emergency incident are reached as incident managers consider three main incident priorities: Life Safety (both the occupants and the responders), Incident Stabilization and Property Conservation.
What are the two types of fire suppression operations?
All fire suppression operations are classified as either offen- sive or defensive. When fire fighters advance hose lines into a building to attack a fire, the strategy is offensive. By con- trast, defensive operations are conducted from the exterior, by directing water streams toward the fire from a safe distance.
What is the first step in developing any fire attack plan?
The success or failure of an effective fireground operation is dependent upon the actions of those first arriving crews. Proper apparatus placement is the first step for a safe and effective interior fire attack.
How do you extinguish a car fire?
If the car fire is relatively small and in the interior, use your car fire extinguisher. (Closing the doors and windows may also smother the fire.) If there’s a small amount of smoke coming from under the hood, pop the release but don’t lift the hood.
