What is the circle of danger when operating a chainsaw and who is allowed within this circle? 10 ft radius, and only the saw operator and control person shall be in this area during cutting. Officer is to monitor conditions and relay orders received from the officer in charge. If possible, officer is positioned as to permit visual contact with the control person. When starting and operating the chainsaw, where should your body be in relation to the chain line? Always keep body to the left of the chain line. If a portable generator is used to power an exhaust fan, what is the ideal length of the electrical cord? 50 feet or less - electrical cords of longer length reduce the efficiency of the fan and may result in damage to the equipment being used. Distance is not a problem when powering small tools and lights. How often and for who long should portable generators be tested? Weekly, for 15 minutes. During this time, operate all lights for 5 minutes to test for proper working order of lights and generator under load. If lamps do not light while testing or using, check bulbs for tight connection. If after checking the bulb connection the light fails to operate, replace with a new bulb. If the light still fails to operate, send the entire light assembly to Technical Services for repair. What is the length of the PSS? What is the load capacity of the hook? The length of the kernmantle rope of the PSS is 50 ft.

Dirty Brown, Yellow Brown, Gray Yellow, and Dense Black Smoke. What are the size measurements of the Vacant Building markings and where are they placed? 18"x18" with 2" wide lines. Markings should be placed alongside Front Entrance in line with area immediately over the front entrance. Can also be made at other likely means of access. Should NOT be made on sealed doors or windows. In regards to the Vacant Building DOB Referral Report, Open and Unguarded vs. Structural Integrity Issues - what priority are each? Open and Unguarded - Normal Priority Structural Integrity Issues - High Priority A DOB Referral Report designated as High Priority shall be considered when the severity of conditions is not extremely hazardous or immediate in nature and access issues are not present. A DOB Referral Report designated as Normal priority shall be used for the referral of nonserious conditions that require a follow-up evaluation by the Department of Buildings What is the difference between diesel fires and gasoline fires? Diesel Fires begin slowly but progress rapidly as vapor production intensifies. Gasoline Fires ignite rapidly but is consumed more quickly. Diesel fires will ignite more of the combustible materials in the fire area. If a member can not get in touch with their officer at a fire, who should they contact and in what order? Company Chauffer, the IC, and finally any HT-equipped member. The handie-talkie will hold the IDs of the last how many transmissions? The last 15 transmissions.

In an under-river tube, evacuation of passengers should take place in which direction relative to an operating fan? Evacuation should take place away from any fan operating in the exhaust mode - this will draw fresh air into the faces of evacuating passengers and remove smoke from the area to which they are evacuating. What is the minimum approach distance to catenary wires in Penn Station? 10 Feet, using a fog nozzle on a fog pattern. What is the distance between Blue Lights in the NYC Subway System and the AirTrain? What is the distance between standpipes/gate valves in the NYC Subway? 600 feet in the NYC Subway System, 800 feet in the AirTrain system. In the NYC Subway, gate valves/standpipes are located every 200 feet. What is the primary method for evacuating passengers from a struck AirTrain? What are other options to consider? Primary method is utilizing a Rescue Car. Other options are using the walkway (tracks must be de-energized with grounding straps in place), or using a Tower Ladder if immediate removal is required. How many hours does the power back-up provide for the subway repeater system? 4 hours - this is at continuous repeater operation, so the actual protection can be greater than 4 hours. When a subway repeater system is down, who does the unit notify? Borough Dispatcher What is the minimum safe operating distance from a live 138 kV electrical component with a 30 degree fog stream and a straight stream? What is it for 345 kV? For 138 kV - 15 ft for fog streams, 75 ft for solid streams. For 345 kV - 25 ft for fog streams, 125 ft for solid streams. In a building being constructed, at least one permanent stair must be within how many floors of the working deck? 40 feet or 4 floors In buildings undergoing construction or demolition, the elevator must be no greater than how many floors away from the working deck? 75 feet or 7 floors When setting up Tower Ladder outriggers, does the manual pin go to into the lowest hole or the highest hole? Lowest Hole When setting up Tower Ladder jacks, does the manual pin go into the highest slot or the lowest slot? Highest Slot When stream application is anticipated at street level, how do you want to position the Tower Ladder? Angled in or Parallel to the building How many feet away from an objective is ideal for a Tower Ladder? 32 Feet When will there be sufficient room from the building for the Tower Ladder bucket to drop below the horizontal? 25 feet away from the building. When operating over the crew cab, the tower ladder bucket can generally reach which floor? 3rd Floor and Above How many rowframes could a Tower Ladder potentially cover? 6 rowframes, 3 buildings on a side street. If Tower Ladder is facing downhill, where should we place the turntable relative to the objective? What if it is facing uphill? If facing downhill, place the turntable past the objective. If facing uphill, place the turntable before the objective. If possible, the apparatus should be facing 'downhill'. How far away should the center line of the Tower Ladder turntable be from the building when removing an incapacitated person via the stokes, and what is the preferred positioning of the stokes for doing so? At least 25-30 feet from the building to reach street level and ensure an efficient transfer to EMS, and diagonal positioning of the stokes is the easiest and safest of the three options. When placed to a roof, what is the preferred positions for a tower ladder basket? Over the roof, parapet, or cornice, with the gate parallel to the roofline. When cutting a coffin cut, which cut is the knockout cut? When cutting a peaked roof private dwelling, which cut is the knockout cut? 2nd Cut in a coffin cut, 4th cut in a peaked roof private dwelling (first cut is parallel to the ridge pole). What size cut is made in the roof of a taxpayer? What resources are needed on the roof of a taxpayer? 8 feet by 8 feet (but when this is not possible, the largest possible cut shall be made), two saws and four members - when more than one power saw is working on the roof, a Roof Sector Supervisor must supervise roof operations; this could be a Chief or Company Officer, as designated by the IC, although where roof cutting is critical, a chief should be assigned as the Roof Sector Supervisor. When using the fog nozzle to vent a room, how far back should you stand from the window opening? 4 to 5 feet, and adjust the fog pattern to the width of the opening. What is the minimum amount of portable ladders that should be placed to a one-story Taxpayer and where are they placed? 5 portable ladders (for a building that fronts the street on all sides) - each side should be covered, with a minimum of two in the front, where they will be placed to indicate the boundaries of the fire building or the location of division walls within the boundaries of the fire. In a taxpayer, when would you call for an extra Engine and Ladder? When would you transmit a Second Alarm? Call for an extra engine and ladder when there are two handlines operating on an advanced fire. Transmit a second alarm for extension to the cockloft, adjoining occupancy, or an advanced fire in the cellar. Where is the second line stretched in a Church fire when the main body of fire is on the first floor? It is stretched and charged outside the fire building as a back-up for the first line. If not needed as a back-up, it can be used to extinguish any fire in the cellar. Who is responsible for ensuring the cellar of a Church is examined for fire? While the first ladder company attempts an examination of the cellar for fire, while the second due ladder ensures it. In terms of arson, what is a plant? Material arranged to start and feed initial fire. (candles, matches, etc) In terms of arson, what is a trailer? Material arranged to spread fire. (rags, paper, etc) The danger of secondary collisions occur during which kind of traffic volume? Light to moderate traffic A blocking apparatus should be placed how many feet behind the first operating unit to create a safe working area? 50 Feet What is the formula used to determine flare distance using the highest estimated speed? (MPH x First Number of MPH) + 60. Example: 30mph (highest ESTIMATED speed - NOT speed limit) 30x3=90 90+60=150 The first flare is placed 150 feet back from the incident. What does the IC have to do when determining where to cross a divider on a highway? (1) Stop traffic in both directions (2) Visually identify the crossing (3) Test the surface on the opposite side of the barrier using a tool (4) Communicate the location to all members (5) Clearly mark the location with cones/barrier tape (at night or reduced visibility use lighting) This shall be the only means of access and egress, and if this safe crossing cannot be established then members shall not cross any barrier, divider, or highway separation.
