Passive Fire Resistance
How often do fires
actually break out?
Worldwide, about 4 million fires
break out every year, claiming
more than 15,000 human lives,
costing some £ 40,000 million
and causing inestimable
ecological and cultural damage.
Hilti firestop systems have been
developed to reduce the amount
of damage, to protect human
lives and to avoid hazards. All
Hilti products have been tested,
inspected and approved
according to stringent standards
internationally.
Why are firestop
systems used and how
do they work?
All system used for passive fire
prevention serve the purpose of
preventing flames, heat, smoke
and toxic gases from spreading
to neighbouring rooms or other
floors in the event of a fire.
Wherever undesirable openings
can appear because of melting
cables or pipes during a fire,
intumescent materials are the
answer to the problem. Under
the influence of heat, they
expand up to seven times their
original volume quickly and
effectively and permanently

Notice about approvals
■ When making a cable or pipe seal using Hilti CP 611 A
intumescent firestop mastic, national approvals must be
observed in principle. Please refer to them for
restrictions as to opening size, type and thickness of wall or floor,
maximum pipe and cable diameter, etc.
■ For maintenance reasons, a penetration seal could be
permanently marked with an installation plate. In such a case,
mark the installation plate and fasten it in a visible position next
to the seal.
Installation instructions for CP611A
(Seal for flammable pipe up to 40mm diameter)
■ Clean joint and joint sides, The joint sides must be in sound
condition, dry and free of dust and grease.
■ Insert backfilling material (mineral wool)
Leave sufficient joint depth for applying the sealant.
■ Apply the fire prevention sealant from both sides of the joint. The
use of a manual dispenser
(e.g. Hilti CB 200-P1) is recommended.
■ Smooth the joint/sealant. Use soap solution or smoothing agent
and smooth carefully with a finger or narrow spatula to give a
concave surface. The working time of CP 611A is 10 to 30
minutes. The completed application should be left undistrubed for
48 hours.
■ Cleaner can be used to clean around the joint or
remove surplus sealant before it has cured.
