Question 1

If the usable floor space is unknown, then deduct ________ percent of the total area available to estimate the usable area.

Accepted Answer

The answer of If the usable floor space is unknown,...

Question 2

Most types of firestop putty have ________ properties.

Accepted Answer

Intumescent properties are the best for firestop putty because they expand when exposed to heat, creating a barrier that seals off the fire and prevents it from spreading. Water based, cementitious, and silicone based firestop putties may also have their own uses and advantages, but they do not offer the same level of fire protection as intumescent putties.

Question 3

A ________ eliminates the need to remove or install materials.

Accepted Answer

A fire-rated pathway device is designed to allow for the passage of cables or other materials without the need for removal or installation, maintaining the fire rating of the barrier.

Question 4

You are designing a firestop system for a boiler room that will have conduits coming from the service provider maintenance hole into the building. Which test rating will address the firestops ability to resist breakdown from water damage?

Accepted Answer

The W rating addresses the firestop's ability to resist water damage. It is important to consider this rating in areas where conduits or pipes may be exposed to moisture or water, such as a boiler room.

Question 5

In addition to voice and data services, an equipment room (ER) can be designed to include all of the following EXCEPT:

Accepted Answer

An equipment room (ER) typically includes telecommunications and security systems, but building electrical service monitoring and controls are generally part of the building's electrical infrastructure, not the ER.

Question 6

Cementitious materials are ________ based materials.

Accepted Answer

Cementitious materials are dry powder-based materials. They primarily consist of a mixture of cement, water, and aggregates such as sand, gravel, or crushed stone.

Question 7

An isolated ground receptacle may be identified by:

Accepted Answer

An isolated ground receptacle may be identified by either a beige coloring with an orange triangle on the face or continuous orange coloring. The letters IG are not always present on the receptacle to signify an isolated ground. Proximity to the PDU does not determine whether a receptacle is an isolated ground.

Question 8

Surge currents due to lightning and other sources MUST be ________ before they penetrate the infrastructure.

Accepted Answer

The answer of Surge currents due to lightning and other...

Question 9

You have determined that the equipment room (ER) you are designing will be the minimum size of 15 sq m (160 sq ft) and is servicing 80 but architectural changes will add 175 , which will require you to add a horizontal cross-connect (HC). What size should the equipment room (ER) be?

Accepted Answer

The answer of You have determined that the equipment room...

Question 10

A(n) ________ system is considered a mechanical firestop.

Accepted Answer

A cable transit system is considered a mechanical firestop as it involves physical components to block the passage of fire and smoke through openings.

Question 11

In a telecommunication room (TR), the ________ is the facility used to make cross connections from the backbone cable to the horizontal cable.

Accepted Answer

The horizontal cross-connect (HC) is the facility used to make cross connections from the backbone cable to the horizontal cable in a telecommunication room (TR). The entrance facility (EF) is the point where the service provider's cabling enters the building, the intermediate cross-connect (IC) is a distribution point between the main cross-connect (MC) and the horizontal cross-connect (HC).

Question 12

Which of the following is a nonmechanical firestop system?

Accepted Answer

Firestop blocks are nonmechanical as they do not involve moving parts or mechanical operations, unlike the other options listed.

Question 13

You are designing a cabling system for a chemical plant. What type of device is needed to prevent the spread of fire along the cable other than the barrier penetrations?

Accepted Answer

The answer of You are designing a cabling system for...

Question 14

Firestop ________, in conjunction with steel wedging plates, go in a steel cable tray.

Accepted Answer

The answer of Firestop ________, in conjunction with steel wedging...

Question 15

You are designing a firestop system for a hospital with several floors that have isolation rooms. Air leakage control is important to ensure rooms are sealed and restrict the spread of disease. Which firestop test rating should you use to ensure air leakage compliance?

Accepted Answer

The L rating is the appropriate choice for this scenario as it measures air leakage. The F rating measures the ability of a firestop to prevent flame and smoke penetration, the T rating measures temperature transmission, and the W rating measures water leakage.

Question 16

A fire ________ is a contained area that is completely enclosed by fire resistant walls, floors, and ceilings.

Accepted Answer

A fire zone is a designated area that is enclosed by fire-resistant barriers to prevent the spread of fire.

Question 17

The F rating for a framed wall/stud wall is ________ hour(s).

Accepted Answer

A framed wall/stud wall can achieve a fire-resistance rating of up to two hours depending on the materials used and the configuration of the wall.

Question 18

A building can have multiple equipment rooms (ERs) for all of the following reasons EXCEPT:

Accepted Answer

ERs are specifically designed to house networking and communication equipment, not office and work space. The other options listed are all valid reasons for having multiple ERs in a building.

Question 19

You are designing the cabling infrastructure for a lab office building that will frequently change tenants. The owner will be responsible for all of the infrastructure that feeds each floor to include the telecommunication rooms. Which firestop method will best suit the owners needs?

Accepted Answer

Firestop pillow systems are ideal for environments where cables are frequently added or removed, as they can be easily adjusted and reused, making them suitable for a building with changing tenants.

Question 20

What type of material does NOT support combustion even under accelerated conditions?

Accepted Answer

Fire proof materials are able to withstand flames and high temperatures without catching fire or supporting combustion. Fire break, fire resistant, and fire retardant materials are all designed to slow or stop the spread of fire, but they may still be able to catch fire under certain conditions.
