Car parks

Question 10

Fire safety engineering uses data to design solutions on numerous aspects relating to a fire within a building. This includes what?

Answer 10

Fire detection
Fire suppression
Compartment fire behaviour
Human behaviour

Question 11

What does HVAC stand for?

Answer 11

Heating, ventilation and air conditioning

Question 12

Compartmentation only works if all imperfections within the building, or breaches made by services passing through the compartment walls and / or floors, are adequately sealed. Name the different types of seals

Answer 12

Linear joint seals - between fire resisting elements of building construction, e.g - junction between a wall and a ceiling

Penetration seals - where services pass through fire separating elements and / or compartment walls / floors

Open state cavity barriers - used to prevent spread of fire between horizontal or vertical cavities in external walls where a continuous air gap needs to be maintained between elements of a building

cavity barriers - to subdivide large roof spaces, under floor voids etc

Question 13

Gas fire suppression systems work by starving a fire of oxygen or heat and therefore eliminating the fire. True or false?

Answer 13

True

Question 14

Name three types of drenchers

Answer 14

Roof drenchers - positioned on the roof ridge and throw a curtain of water upwards

Wall or curtain drenchers - Throw a curtain of water over openings or portions of a building most likely to admit fire

Window drenchers - Positioned horizontally level with the top of a window as to protect the opening

Question 15

What are the functional objectives of fire safety?

Answer 15

To protect:
Life
Property
Environment

From the effects of fire

Question 16

Smoke control systems are mechanical systems that control the movement of smoke during a fire. What are they most commonly used for?

Answer 16

To protect occupants being sheltered in one place
To protect occupants whilst evacuating

Question 17

What kind of risks should an incident commander be aware of in relation to dry powder fixed installations?

Answer 17

Can reduce availability of oxygen in an area when discharged
May be toxic or contain irritants
If moisture is present the powder can turn into an acidic solution
