to the extent practicable. (See appendix A)
1.4 Administration
- The Fire Commissioner of Canada or the authorized
representative of the Fire Commissioner (henceforth referred to
as FC) is responsible for the administration and enforcement of
this standard.
- This standard is not to be interpreted as permitting
practices specifically prohibited by provincial, municipal, or
other federal legislation.
- Where reference is made to other codes and standards, unless
otherwise stipulated, the reference shall be to the latest
edition including amendments to that code or standard.
1.5 Definitions
- Certain terms used in this standard are defined to ensure
understanding of their meaning and intent.
-
Contained use area means a
supervised area containing one or more rooms in which occupant
movement is restricted to a single room by security measures not
under the control of the occupant, (see appendix A); (zone de
détention cellulaire);
free access means access without
barriers that require keys, special devices, remote releasing
devices, or specialized knowledge of the opening mechanism, to an
approved safe area, (see appendix A), (accès libre);
impeded egress zone means a
supervised area in which occupants have free movement but require
the release, by security personnel, of security doors at the
boundary before they are able to leave the area, but does not
include a contained use area, (see appendix A), (zone à sortie
contrôlée);
listed means equipment or materials
included in a list published by a nationally recognized
organization concerned with product evaluation, that maintains
periodic inspection of production of listed equipment or
materials and whose listing states either that the equipment or
material meets appropriate standards or has been tested and found
suitable for use in a specified manner, (répertorié);
living unit means a building or
portion thereof containing sleeping accommodation for inmates,
and may include ancillary areas such as lounges, kitchenettes,
showers, and janitor's closets. Family visiting units are not
considered to be living units, (unité résidentielle).

Explanatory material
A-1.2(b) The FC should be consulted for direction
on fire protection requirements for such buildings. As a minimum,
farm buildings must comply with the applicable requirements of
the NBC and Canadian Farm Building Code.
A-1.2(c) Community residential facilities
includes both community residential centres and community
correctional centres. Although sometimes referred to as
institutions for administrative purposes by CSC, they are not
institutional occupancies as defined by the NBC. Usually these
facilities are considered to be residential occupancies as
defined by the NBC.
A-1.3(b) The extent of application of this
standard to the upgrading of existing buildings should be based
on judgement and the merits of each case. The FC should be
consulted for advice in assessing risk and determining
priorities.
A-1.5(a) Any building with detention rooms is a
contained use area. The most common examples are medium and
maximum security living units.
In order to qualify as having free access,
all required means of egress from a building or area must
be without barriers. Otherwise, egress is considered to be
impeded.
Impeded egress zones are buildings or portions
thereof in which the occupants have some freedom of movement, but
from which they cannot exit freely. Typical examples are
operational buildings such as dining halls, recreation buildings,
and training shops. Note that if any of the required means
of egress are locked, egress is considered to be impeded.
A-3.2 (a) The following are examples of occupancy
classifications that would apply to buildings having free
access:

A-3.2(b) These limits are placed on the size of
combustible buildings for fire risk management reasons. The
presence or absence of sprinkler protection has no effect on the
application of the area limits in this table.
A-3.3(b) Individual cell doors may be keyed from
one side only.
A-3.3(c) CSC has issued directives giving
guidance and priorities for installing remote release devices on
existing buildings.
A-3.5 Fire separations should be provided between
all major functional areas. The fire resistance ratings of these
separations should be consistent with the ratings required by the
NBC for the separation of major occupancies. For example: an
industrial workshop having impeded egress is by definition a
Group B Division 1 occupancy. However, for the purposes of
determining an appropriate fire separation, Table 3.1.3.A of the
NBC should be applied as if the workshop was an F2 occupancy.
A-3.5(b) The term industrial use is used
in this clause in lieu of industrial occupancy to avoid
confusion with the occupancy classification as defined by the
NBC. As noted above, an industrial use such as a workshop is
still by definition a B1 occupancy if the means of egress are
locked.
A-3.6(c) Padded materials should be evaluated on
the basis of full-scale room fire tests that approximate the room
dimensions and severe ignition scenarios to be expected in an
institutional setting. One such test is California Standard
No. 12-42-100, Room Fire Test For Wall and Ceiling
Materials.
A-4.1 CSC has issued directives giving guidance
on fire hazard control in inmate-occupied areas. For further
details see CSC Commissioner's Directive No. 345 - Fire
Safety.
A-4.3 CSC Commissioner's Directive No. 345 - Fire
Safety - contains further guidance on combustible furnishings
permitted in inmate-occupied areas.
A-4.3(a) In the past, the following materials
have been found to be acceptable:
- core materials of neoprene foam, flame retardant treated
cotton, or Cordelan staple fibre, and
- covers of flame retardant treated cotton ticking or a flame
retardant synthetic fabric.
Other materials should be evaluated on the basis
of tests representative of the severe ignition scenarios to be
expected in an institutional setting. One such test is California
Technical Bulletin No. 121, Flammability Test Procedure for
Mattresses for Use in High Risk Occupancies.
A-4.3(c) The fire retardancy of furniture should
be evaluated on the basis of full-scale fire tests representative
of the severe ignition scenarios to be expected in an
institutional setting. One such test is California Technical
Bulletin No. 133, Flammability Test Procedure for Seating
Furniture for Use in High Risk and Public Occupancies.
A-4.4(c) In a sprinklered floor area, the
preferred method of fire suppression for cooking equipment is
automatic sprinklers.
A-5.1(d) In areas with 2-stage fire alarm
systems, a listed voice communication system is not required if
there are other communication systems available that are adequate
and reliable. In living units these systems should include all of
the following: portable radios; public address system; and
telephones at control posts.
A-5.2(a) For the purposes of this clause, family
visiting units are not considered to be living units.
A-5.2(f) Where practicable, main valves should be
located in a secure room or area having access directly from the
exterior.
A-5.2(g) These security requirements are intended
to be in addition to normal valve supervision. Supervision alone
is not sufficient to prevent tampering in this type of
occupancy.
A-5.3(a) The standpipe requirements exceed those
of the NBC because: firefighting access to buildings is generally
limited by security constraints; the available public fire
department resources at most institution locations are limited;
and fire hose systems are used by institutional staff to provide
an initial firefighting response.
A-5.3(e) It is assumed that such buildings would
have adequate fire department access and coverage from fire
hydrants. If this is not the case, then the 65 mm connections
should be installed.
A-5.3(f) Combined systems are a cost-efficient
measure, particularly in view of the requirements of clauses (a)
and (b). However, approval must be site-specific to ensure that
the combined system can meet both fire protection and security
criteria.
A-5.7(b) It is recognized that strict compliance
may not be practical with some institution designs. In such cases
the FC, the Fire Department Official, and the Administrative
Official should consult on alternative firefighting
provisions.
A-6.1(d) Due to the limitations on fire
department response at most institutions, a high residual
pressure is specified so that one or two hose streams can be
supplied directly from a hydrant.
A-8.3(a) CSC Commissioner's Directive No. 345 -
Fire Safety - includes requirements for the investigation and
reporting of fires and false alarms by CSC staff.
A-9.1 There is usually only one MCCP in an
institution. The requirements of this Section are not intended to
apply to local control posts.
