Question 172

Officers should have some familiarity with NYC’s natural gas infrastructure. Of the following choices, which is incorrect? A) A “NC” stamped on a tag near the service meter indicates there is no curb valve or service valve. An “EFV” stamped on a tag near the service meter indicates an “excess flow valve” exists in line on the service pipe, which should limit or stop excess flow. B) Curb valves/service valves are usually found on the sidewalk side of the curb and shut the gas supply to the entire building. They are usually recessed in from the curb and are covered with a 4” X 4” square or round, brittle concrete or steel cover which may be sitting on top of a plastic or wooden plate. C) Con Edison Gas main valves have ID numbers on tags on top of the valve cover. National Grid main valve covers are identified by an ID number stamped on the North side of the cover; however, these numbers may be difficult to see. D) Low pressure (¼ psi) Distribution Mains generally do not have valves and isolating sections of low pressure Distribution Mains requires plugging or “squeezing off” the pipe while still under pressure (live). Only the Utility Company can safely plug or squeeze-off Distribution or Service Mains.

Answer 172

ANSWER: C) Con Edison Gas main valves have ID numbers on tags on top of the valve cover. National Grid main valve covers are identified by an ID number stamped on the North side of the cover; however, these numbers may be difficult to see. (EP Gas 4.4) * Con Edison Gas main valves have ID numbers on tags INSIDE of the valve cover. * National Grid main valve covers are identified by an ID number stamped on the North side of the COLLAR, UNDERNEATH the cover; however, these numbers may be difficult to see.

B) Steam pressures in generating plants can be as high as 2,000 psi with temperatures reaching 900ºF. Steam pressures in the buried supply piping and in supplied buildings can be as high as 170 psi and temperatures as high as 350ºF. C) Steam can be frequently seen rising from the ground or from steam manholes in New York City. A vent stack with a blue stripe on top of it indicates that the steam is the result of a leaking steam main, and the steam is being directed away from traffic. D) A high energy line break in the street may generate noise, making radio and verbal communication ineffective in the immediate vicinity of the release. Prepare for decontamination of civilians, firefighters, bunker gear, tools, equipment and vehicles and consider shutting the HVAC systems of nearby buildings.

Answer 173

ANSWER: C) Steam can be frequently seen rising from the ground or from steam manholes in New York City. A vent stack with a blue stripe on top of it indicates that the steam is the result of a leaking steam main, and the steam is being directed away from traffic. (INCORRECT) (EP Steam 1.2, 2.2, 4.2, 4.3) * Steam frequently seen rising from the ground and from steam manholes is usually not the result of a high energy line break. More often, it is the result of water from a heavy rain or a leaking sewer or water main, contacting the steam pipe and turning to steam. A vent stack with a blue stripe on top of it indicates that the steam is the result of a WATER LEAK, NOT a leaking steam main.

Question 174

When encountering an occupied, stalled suspended scaffold with workers on it, you would be correct to have your members take each of the following actions except? A) If a wire rope hoist is jammed within the unit, never allow workers to attempt to continue to operate the hoist. B) If a scaffold is in reach of a tower/aerial ladder, this may be used to effect removal. Window removal/glass cutting to retrieve stranded workers shall be performed by a Rescue or Squad company. C) If an electric hoist motor overheated due to an overloaded scaffold and a reset button is present, immediately have a worker push the reset button on the hoist. D) If workers must be hauled in through an open window and they need to disconnect from their safety line to enter, a life saving rope or high angle rope secured to a substantial object or high angle rope system must be attached to the worker’s harness before disconnecting them from their rope.

Answer 174

ANSWER: C) If an electric hoist motor overheated due to an overloaded scaffold and a reset button is present, immediately have a worker push the reset button on the hoist. (INCORRECT) (EP Scaffold 5.3, 5.4) * If an electric hoist motor overheated due to an overloaded scaffold and a reset button is present, ALLOW IT TO COOL FOR AT LEAST 15 MINUTES, then have a worker push the reset button on the hoist. A Note: If they operate the hoist, it can sever the wire rope and cause the end of the scaffold to fall.

Question 175

Engine 256, a single engine arrives at a major gas leak in a multiple dwelling prior to any other unit. Which action taken by the engine company officer was CORRECT? A) Observing no odor in the street, the engine officer turned on his gas meter & FDNY issued flashlight upon detecting an odor in the lobby. B) Once the odor was discovered in the lobby, the officer proceeded to 3B, the apartment of the caller. C) Once it was determined the leak was from a construction site next door, the officer had the members position themselves outside the potential blast zone and stretch a 1¾ handline for a defensive position. D) A fog stream was stretched to protect a worker plugging a natural gas pipe. The same line was used to dissipate the leaking gas in the street.

Answer 175

ANSWER: B) Once the odor was discovered in the lobby, the officer proceeded to 3B, the apartment of the caller. (EMERGENCY PROCEDURES – NATURAL GAS 6.5) * ENGINE OFFICER to callers apartment / LADDER INSIDE TEAM would go to basement upon getting an odor from the lobby. A – Activate gas meter BEFORE entering the building C - 2½ hose and larger streams D – Fog streams should NOT be used to dissipate natural gas venting outside of the structure; let the gas vent naturally.

Question 176

Question 178

A newly assigned member to Captain Blue’s unit was questioning standard operating procedures for water rescues. The Captain informed this member of a number of tactics; one of which was incorrect. Which procedure was incorrect? A) Water Safety Units have been issued a Water Safety Kit to use when a water rescue trained company is not on the scene; when arriving first, these Companies may take action using this kit. Entry into the water should only be attempted when consistent with safety and after a proper size-up. B) Roll Call is the time to determine which member or members will enter the water if the emergency requires. It would not be a good practice to assign your primary water rescuer as a riding position, e.g. “nozzle position.” C) The company officer will usually assume the position of “Rescue Coordinator” and shall be located where they can observe and direct the whole operation. In a 4-firefighter Engine Company, the officer will also assume the responsibilities of the “Spotter” until an additional unit arrives. Tools include the handie-talkie, flashlight and thermal imaging camera, if available. D) Inflatable water rescue hose can be used as a flotation device and can be deployed in a straight line or a loop. Each length of 2 ½ of hose can keep afloat approximately 20 people.
