A-9.4.2.4.(1)

ADD the following Appendix Note:
A-9.4.2.4.(1) Specified Loads for Attics with Limited Accessibility.

Typical residential roofs are framed with roof trusses and the ceiling is insulated.

Residential trusses are placed at 600 mm on centre with web members joining top and bottom chords. Lateral web bracing is installed perpendicular to the span of the trusses. As a result, there is limited room for movement inside the attic space or for storage of material. Access hatches are generally built to the minimum acceptable dimensions of 500 mm by 700 mm, further limiting the size of material that can be moved into the attic.

With exposed insulation in the attic, access is not recommended unless protective clothing and breathing apparatus are worn.

Thus the attic space is recognized as uninhabitable and loading can be based on actual dead load. In emergency situations or for the purpose of inspection, it is possible for a person to access the attic without over-stressing the truss or causing damaging deflections.

Add the following Appendix note that was noted in the July 1999 NBC revision.

A-9.10.9.16.(4) Separation Between Dwelling Units and Storage or Repair Garages. The gas tight barrier between a dwelling unit and an attached garage is intended to provide protection from carbon monoxide and gasoline fumes entering the dwelling unit.
Building assemblies incorporating an air barrier system will perform adequately with respect to gas tightness, provided all joints in the airtight material are sealed and reasonable care is exercised where the wall or ceiling is pierced by building services. Where a garage is open to the adjacent attic space above the dwelling unit it serves, a gas-tight barrier in the ceiling of the dwelling unit will also provide protection. Unit masonry walls forming the separation between a dwelling unit and an adjacent garage should be provided with two coats of sealer or plaster, or covered with gypsum wallboard on the side of the wall exposed to the garage. All joints must be sealed to ensure continuity of the barrier. (See also Sentences 9.25.3.3.(3) to (8))
