The Importance of Passive Fire Protection
Facts about Fire
Worldwide, a fire breaks out every
7 seconds.
Annual UK Statistics:
● Cause of 700 deaths
● Business Disruption £1.3bn (£3.4m
a day)
● Annual costs of Arson: £2.4bn
● Government Reports Overall £7bn
Cost to the UK Economy
● Fire makes up 44% of all insurance
claims

The Importance of Passive Fire Protection
Facts about Smoke
● Smoke travels at between 15 and
90 metres per minute
● 67% of fire related deaths are
through smoke inhalation
● 44% of deaths are people who
were not in the room of origin
● 47% of survivors could not see
more than 3.5 metres.

About Fire Safety Law in the UK
• RRO (FSO) Regulatory Reform Order;
Fire Safety Order 2005
• The Fire (Scotland) Act 2005
(Fire Safety (Scotland) Regulations 2006)
Summary>Building owner to have full fire risk assessment
The enforcers can visit premises without notice
and ask to see a fire risk assessment and enforce
necessary works, fines and prosecution, if they feel
there is a breach any areas of fire safety.

What type
of buildings
doesB)the RRO & F(Scot.)A affect ?
Breaching
fire separation
(Appendix
‘To ensure effective protection against fire,
walls and floors providing fire separation must
form a complete barrier, with an equivalent
level of fire resistance provided to any openings
Educational
Healthcare
Factories &
such Premises
as doors, ventilation ducts,
pipe passages Warehouses
Premises
Large Places of
Assembly
or refuse chutes.
The passing of services such as heating pipes
or electrical cables through fire-resisting
partitions leaves gaps through which fire and
smoke
may spread.
This should
be rectified
Offices
&
Residential
Care
by suitable fire stopping and there are many
Shops
Premises
Theatres &
Cinemas
Apartments &
Hotels
proprietary products available to suit particular
types of construction. Such
products should

contractors.’

Flames
Gases
Integrity*
Load bearing
Capacity*
Measures the
ability of a
Flames product to prevent
gas & flame to
Gases
pass through it in
a fire
Heat
Measures the
structural stability
Additional testing…
of the product in
fire
Cyclic testing
30 year age testing
Explosion resistance
Insulation*
Fixing suitability
Measures the ability of
Acoustics
Air sealing
Heat an element to insulate,
i.e.Movement
how long it takes
Load bearing capacity
capabilities
Flames for the non-fire side of
Seismic
Mold resistance
the
element to reach
Gases
Water resistance 180°
*All three criteria are measured in hours and minutes.

Building Regulations – what happens if the fire
test doesn’t cover the application
● From Appendix ‘A’ 1A a qualified fire
engineer can make a judgement based on
test results:
“or assessed from test evidence against
appropriate standards”
● This judgment cannot be in the form of a
fax or letter from the supplier
● It must include a detailed drawing and/or
description of the application
● There must be a reference to more
onerous testing.
Hilti can provide that engineering judgement
