RULING

  1. The Applicant

Mr. Norman Pye, Northern Pride is the holder of a permit under the Building Code Act, 1992 to construct a poultry processing plant at 20 Scott Avenue, Paris, Ontario.

  1. Description of Construction

The building of Northern Pride Products Inc. is a new one storey processing plant (Group F, Division 2 major occupancy) of non-combustible construction with a building area of 8,960 square feet (832 square metres). The building does not have a fire alarm system, a sprinkler system or a standpipe and hose system. Rigid foamed plastic insulation is used in the construction of the walls and ceilings of the Production Area, Cold Room, Shipping Room and Cooler. "Kemlite Glasboards", a type of fibreglass reinforced plastic panels, are installed over the rigid foamed plastic insulation.

The construction of the building is regulated by Article 3.2.2.51 of the Building Code. and may be of combustible or noncombustible construction used either singly or in combination, and the roof is not required to have a fire-resistance rating. The building is constructed of masonry loadbearing walls, open web steel joists and steel deck.

  1. Dispute

The dispute between the Applicant and Respondent concerns whether the wall and ceiling installations meet the requirements of Sentence 3.1.4.2.(1) of the Building Code.

  1. Provisions of the Building Code

Sentence 3.1.4.2.(1) Protection of Foamed Plastics

(1) Foamed plastics which form part of a wall or ceiling assembly in combustible construction shall be protected from adjacent spaces in the building, other than adjacent concealed spaces within attic or roof spaces, crawl spaces, and wall assemblies, by

(a) one of the interior finishes described in Subsections 9.29.4. to 9.29.9.,

(b) sheet metal mechanically fastened to the supporting assembly independent of the insulation, not less than 0.38 mm (0.015 in) thick and with a melting point not below 650oC (1202oF) provided the building does not contain a Group B or Group C major occupancy, or

(c) any thermal barrier that meets the requirements of Sentence 3.1.5.11.(2). (See Appendix A.)

  1. Applicant's Position

The Applicant maintained that the plant was approved by Agriculture Canada. Due to the nature of production in the plant which requires surfaces to be non-porous to prevent bacteria, the Applicant indicated that the `glasboard' is a suitable material because it can be easily cleaned. As the plant environment is very wet and damp and there is no hydro in the walls, there is a little chance of a fire hazard. Furthermore, there is a low occupant load of 22.

  1. Chief Building Official's Position

The wall and ceiling construction include the installation of foam plastic insulation which is not protected from adjacent spaces by a thermal barrier tested in conformance with CAN4-S124-M "Standard Method of Test for the Evaluation of Protective Coverings for Foamed Plastic" as required under the Building Code. The Applicant has installed "Kemlite Glasbord" fibre-glass reinforced plastic panels over the foam plastic insulation. "Kemlite Glasbord" has not been tested to the required standard specified in Sentence 3.1.4.2.(1). An Order to Comply was issued by the Respondent to the Applicant to provide protection between the foamed plastic insulation and the "Kemlite Glasbord" panels in accordance with the requirements of Sentence 3.1.4.2.(1) of the OBC.

  1. Commission Ruling

It is the decision of the Building Code Commission that the installation of `Glasbord' CPI over 1-1/2" S.M. board provides sufficiency of the compliance with Article 3.1.4.2. of the Building Code.

  1. Reasons:

i) The building is small (i.e) single storey and 8960 sq.ft. and is subdivided into areas no greater than 4500 sq. ft in area by masonry walls and metal doors.

ii) The distance of travel to exits is less than required by the Building Code.

iii) The processing area is damp and high pressure hose stations are available which are intended for wash down but could be used for fire fighting purposes.

iv) Ambient temperature alarms are located in the processing area and storage to which would alert the occupants of a fire when temperatures exceed 45o and 34o F respectively.

v) The occupant load is low (i.e. 22 persons).

Dated at Toronto this 22nd day in the month of July in the year 1997 for application number 1997-32
