Damage control central

The three responsibilities of the at-sea fire party are as follows:
(1) Respond immediately to fire alarms when the ship’s repair parties are not manned;
(2) extinguish small fires without disrupting other ship operations;
(3) control fires until ongoing sensitive critical evolutions can be secured and GQ stations can be manned and ready.

What person is in charge of the fire party at the emergency scene and directs the efforts of
the fire party to combat the emergency situation? The on-scene leader

Investigators normally operate in pairs, travel assigned routes, and report conditions to the
repair locker.

Class A fires leave embers or ashes and must always be overhauled.

What type of fire occurs in electrical equipment? CHARLIE

What type of fire occurs in the vapor-air mixture over the surface of flammable liquids? BRAVO

A fire produces carbon monoxide (CO) when there is not enough oxygen present for the complete combustion of all of the carbon in the burning material.

A fire produces carbon dioxide (CO2) when there is complete combustion of all of the carbon in the burning material?

Under normal conditions, oxygen accounts for what percentage of the chemical composition of air? 20.8%

Which of the following processes is NOT a method of transferring heat? (4) Glaciation

Heat, fuel, and oxygen are the three components of the fire triangle.

Water is a cooling agent and the sea provides a ship an inexhaustible supply.

AFFF can be used alone or in combination with PKP.

Dry chemical powders interrupt the chemical reaction of the fire by suspending fine particles in the fire. These particles put a temporary screen between the heat, oxygen, and fuel and maintain this screen just long enough for the fire to be extinguished.

Halon 1301 is a dense colorless and odorless gas that does not conduct electricity or leave a residue.

What type of valve automatically proportions the correct amount of AFFF concentrate with seawater? Balancing valve

When using the CO2 hose-and-reel system, you should always direct the CO2 discharged from the hose toward the base of the fire.

Before operating an installed CO2 system, you should ensure all openings in the compartment are closed and the ventilation system for the space is secured.

Halon systems are used to extinguish fires that are beyond the capacity of fire extinguishing equipment, and where abandonment of the space is necessary.

The full discharge of the gas from a Halon 1301 system into a protected space is completed in how many seconds? 10 seconds

On a Navy ship, what personnel are responsible for damage control? All hands

After each use, all damage control kits and repair locker equipment must be inventoried to meet what requirements? PMS

What holes should be given priority when plugging is needed? Holes at the waterline or low side

The one very important thing to remember about flooding is that a ship can sink just as easily from a series of small and insignificant looking holes as it can from one large and more dramatic looking hole.

Plugs made of softwood, such as yellow pine or fir, are quite effective for plugging holes up to what size? 3 inches by 3 inches

It is best to wrap a plug with lightweight cloth before inserting it because the cloth keeps the plug in place and fills gaps between plugs.

What type of patches are effective for use over holes that have jagged edges projecting inboard? Box

Which of the following woods are best to use for the construction of shores? Douglas fir and yellow pine

A shore is a portable beam, a wedge is a block, triangular on the sides and rectangular on the butt end, and a shole is a flat block that may be placed under the end of a shore to distribute pressure.

A strongback is a bar or beam of wood or metal that is used to distribute pressure or to serve as an anchor for a patch. The strongback is often shorter than a shore.

What is the fully extended load for the model 6-11 steel adjustable shore? 6,000 pounds

A steel wedge is considered more valuable as a prying tool than for actual shoring.

The most rapid and accurate way to measure a shore for cutting is to use an adjustable shoring batten.

Which of the following types of equipment are available on the ship in case a space is inaccessible due to damaged doors, hatches, and/or scuttles? The Portable Hydraulic
Access and Rescue System (PHARS) and the Portable Exothermic Cutting Unit
(PECU)
