Quiz #3 Flashcards
According to TB #003 - Type IV Buildings - Aluminum, Aluminum has a melting point of approximately _____ degrease Fahrenheit, a temperature which can be expected about ___ minutes after the start of most fires.
1300; 10
According to TB #008 ELECTRICAL HAZARDS, When cutting wires attached to a building, use the following safeguards…
-Wear full PPEs. Protective goggles must be worn. Consider donning SCBA facepiece
-Use mechanical axe with rubber gauntlet gloves.
-Stand on a dry object. Lock in when working on a ladder
-Be sure all insulated wires leading to the service head are cut
According to TB #008 ELECTRICAL HAZARDS, The apparatus is not insulated from the ground by its rubber tires and may be energized by live wires in the following ways…
-By touching an object that is in contact with a live conductor
-By direct contact with a live conductor
-By way of an extended aerial ladder touching a live conductor
According to TB #008 ELECTRICAL HAZARDS, Aerial ladders must be kept at least ____ feet away from all power lines and devices.
10’
According to TB #008 ELECTRICAL HAZARDS, Guidelines for raising ladders at incidents where electrical hazards exist…
-All members should identify the presence of overhead wires, transformers, etc
-Watch tops of ladders being raised for potential hazards
-Be aware of any conditions that may cause ladders to slip or slide and contact an electrical source
-Be cautious of hand tools used on ladders
According to TB #008 ELECTRICAL HAZARDS, Although water is not a good conductor, incidents such as sheared hydrants where large volumes of water are contacting high-voltage lines should be approached with care. The following procedures should guide first responders’ actions…
-Spot apparatus a sufficient distance from hazard
-Be cognizant that high voltage lines impacted by water from a sheared hydrant may arc or fall at any time
-All members should be alert for additional downed wires or energized exposures
-Unless a life hazard exists, notify and await arrival of LADWP personnel
According to TB #008 ELECTRICAL HAZARDS, Although injuries to firefighters from applying water directly on electrical fires are rare, water streams applied in the vicinity of high voltage should be avoided. When hose streams must be used, the following should be adhered to
-Where possible, extinguish small electrical fires with dry chemical or carbon dioxide extinguishers
-Utilize the 30/33/100 Rule for using hose streams around high voltage
-Maintain a safe distance from the energized equipment. The LADWP also recommends not approaching a high-voltage source closer than one’s body length, so that a fall forward would not cause direct body contact
-Remember the safest tactic regarding the use of hose streams around a high voltage source is to take a defensive stance, let the equipment burn and protect exposures.
According to TB #008 ELECTRICAL HAZARDS, Maintain clearance a minimum of HOW MANY feet beyond the outermost wire of electrical transmission lines.
100’
According to TB #008 ELECTRICAL HAZARDS, Utilize the 30/33/100 Rule when directing hose streams near high voltage in the wildland refers to what 3 in order?
Utilize a 30-degree fog pattern, Maintain a safe distance of at least 33 ft. from energized source, Maintain at least 100 psi to the nozzle.
According to TB#035 Overhaul Procedures, Areas that are deemed to be unsafe for personnel to access shall be completely restricted with?
BOTH fire-line tape, and red and white striped barricade tape
According to TB#035 Overhaul Procedures, the following describe the types of overhaul options available to the IC:
Complete Overhaul
Wet Overhaul
Fire Watch
Thermal Imaging Camera (TIC)
According to TB#035 Overhaul Procedures, When a complete overhaul is performed, overhaul piles shall be established in a location that will minimize any inconvenience to the public, and at a minimum of ( ) feet away from any part of a structure. These areas should be identified in the planning phase for coordination of companies during overhaul.
10’
According to TB#035 Overhaul Procedures, WHAT is not an example of these life-saving procedures.
-Thoroughly ventilating a structure
-Allowing sufficient time for particulate matter to settle
-Expedite operations to limit exposure
-Shield personnel with the proper PPE
-Conducting post-incident decontamination
Expedite operations to limit exposure
