Fire and Explosion

Question 1

How furniture and fittings can have a major effect on fire spread

Answer 1

Increasing the fire loading

Spreading toxic smoke and blocking escape routes

Question 2

3 criteria to determine fire resistance

Answer 2

Resistance to collapse (load bearing capacity)
Resistance to fire penetration (integrity)
Resistance to transfer of excessive heat (insulation)

Question 3

Requirements for fire resistance of hanging curtains, blinds and drapes

Answer 3

All must be non-combustible or inherently flame retardant

Question 4

Types of active protection measures

Answer 4

Automatic detection and suppressions systems

Question 5

Types of passive protection measures

Answer 5

Designed into the physical structure of the building such as load bearing components, compartmentation, fire resistant materials

Question 6

What is compartmentation?

Answer 6

Division of a building into fire resisting compartments to provide time for occupants to escape or take refuge

Question 7

Types of fire stopping products

Answer 7

Coated stone wool batts/boards
Sealant / Mastic coverings
Mortars
Pipe closures
Stone wool mineral fibres and foams

Question 8

Highly Flammable Liquids - V.I.C.E.S

Answer 8

Ventilation
Ignition
Containment
Exchange
Separation

Question 9

Hazardous area zoning for clouds of combustible dust

Answer 9

Zone 20 - Present continuously or for long periods frequently

Zone 21 - likely to occur in normal ops occasionally

Zone 22 - not likely in normal ops, if does will persist for short period only

Question 10

Hazardous area zoning for gases, vapours and mists

Answer 10

Zone 0 - Present continuously or for long periods frequently

Zone 1 - likely to occur in normal ops occasionally

Zone 2 - not likely in normal ops, if does will persist for short period only

Question 11

What is inerting?

Answer 11

Partial or complete substitution of the oxygen content in a flammable atmosphere with an inert gas

Question 12

Risks from Inert atmospheres during maintenance

Answer 12

Cold burns from cold nitrogen stores

Hypoxia, anoxia and asphyxiation due to lack of oxygen

Direct and indirect injury from release of pressurised gas

Question 13

Segregation and storage of flammable, combustible and incompatible materials

Answer 13

Should be in secure compounds in the open air

Away from ignition sources, vulnerable buildings and site perimeter
