Fire and steel construction

Which of the following is not considered a major risk factor in fire in BS 9999, the new British Standard published to provide an alternative approach to the design of fire precautions in buildings to those in Government published documents?

Whether the occupants of the building are familiar with their surroundings.
Whether the occupants of the building are likely to be asleep
Where there is likely to be a fire station nearby
The height of the building

Fire protection thickness can be specified on the basis of default critical temperatures. However, it can also be specified as a function of what other parameters?

Critical temperatures based on the member utilisation
The section factor of the member
The steel grade
All of the above

Fire protection thickness is a function of the section factor of the beam or column. Which of these statements are correct?

The section factor is the cross sectional area in square metres divided by the heated perimeter in metres.
The section factor is the heated perimeter in metres divided by the cross sectional area in square metres.
Short stocky sections will typically have higher section factors than tall, skinny sections.
Fire protection thickness decreases as section factor decreases.

Which of the following are commonly used to provide fire protection of structural beams and columns in the UK?

Boards
Sprays
Thin film intumescent coatings
Reinforced concrete between the flanges

A new British Standard, BS 9999, has been published to provide an alternative approach to the design of fire precautions in buildings to those in Government published documents. Which one of these best describes the fundamental principle behind its development?

Based on an understanding of the factors that create risk in fire
Based on conservative experience
Based on European approaches to the design of fire precautions in buildings
Based on an averaged approach from across the regions of the UK

What is the meaning of time equivalent in fire engineering?

It is the severity of a fire in a compartment in terms of exposure to a standard fire test
It is the time in minutes at which the fire in a compartment will burn above 600°C
It is the period for which a fire will burn based on times measured in other, equivalent, compartments
It is the period of time which is required for the fire brigade to attend and extinguish a compartment fire.

Use of the advanced methods of structural fire engineering developed from the Cardington fire tests will usually lead to what?

No fire protection on the beams or columns
No fire protection on any of the beams
No fire protection on most of the secondary beams
Reduced fire protection on the secondary beams.

Which form of fire protection is most commonly used to fire protect structural steelwork for buildings off-site?

Boards
Sprays
Thin film intumescent coatings
Flexible blankets

How does an element of construction demonstrate that it can perform a fire resisting function if required?

Through trial and error in real building fires
Through a detailed theoretical study
Via a fire test carried out in accordance with a standard acceptable in the country in which that element is to be used
Via tests carried out in the manufacturer’s own furnaces

The maximum period of fire resistance required in Approved Document B to help meet the requirements of the Building Regulation is?

60 minutes
90 minutes
120 minutes
240 minutes
