1. (1) Roofing brackets.

   1. (i) Required use. Roofing brackets shall be used whenever work is to be performed on any roof having a slope steeper than one in four inches unless crawling boards or approved safety belts are used in compliance with this Part (rule).
   2. (ii) Roofing bracket construction. Roofing brackets shall be constructed and installed to fit the pitch of the roof and when in use shall provide a level working platform.
   3. (iii) Roofing bracket installation. Roofing brackets shall be secured in place by nailing, by securely driving into the roof the pointed metal projections which are attached to the undersides of roofing brackets or by means of first grade manila rope or synthetic fibre rope at least three-quarters inch in diameter which is passed over the ridge poles and tied.

2. (2) Crawling boards.

   1. (i) Crawling board construction. Crawling boards shall be at least 10 inches in width and one inch in thickness. Each crawling board shall be provided with cleats which are at least one and one-half inches in width by one inch in thickness. Such cleats shall be spaced at equal intervals across the full width of the board and shall be firmly nailed. Cleat nails shall be driven through and clinched or shall be of the screw type. Crawling boards shall extend from the ridge poles to the eaves when used in connection with roof construction, repair or maintenance.
   2. (ii) Crawling board installation. Crawling boards shall be secured to a roof by ridge hooks or equally effective means.

   3. (iii) Crawling board lifeline. A lifeline in compliance with this Part (rule) shall be strung beside each crawling board.

      (b) High and steep roofs.

      Where any work is being performed in the construction, repair or maintenance of any roof without a parapet at least two and one-half feet in height and such roof is more than 20 feet in height measured from the ground or grade level to the exterior edge of the eaves and the slope of such roof is greater than one in four, a ground-supported scaffold in compliance with this Part (rule) shall be provided. Such scaffold shall be installed beneath the work area with the scaffold platform not more than two feet below the exterior edges of the eaves of the roof. Such scaffold shall be of sufficient width to extend outward at least two feet from the exterior roof edge and the scaffold platform shall be provided with a safety railing constructed and installed in compliance with this Part (rule). In addition, persons performing such work shall be protected against sliding by means of roofing brackets or crawling boards installed and used in compliance with this Part (rule). Such roofing brackets or crawling boards are not required in cases where every employee engaged in work on such roof is provided with and used as approved safety belt or harness securely attached to a lifeline in compliance with this Part (rule).

      (c) Protection of persons using roofing machines.

      Where persons are using roofing machines on any roof which does not have a parapet at least three feet in height installed around the perimeter of such roof, protection from falling shall be provided for such persons as follows:

3. (1) If the work area extends to any edge of the roof, such edge shall be provided with a safety railing constructed and installed in compliance with this Part (rule) or a ground-supported scaffold in compliance with this Part (rule) shall be provided. Such scaffold shall be installed the length of the work area with the scaffold platform level with the roof edge elevation. Such scaffold shall be of sufficient width to extend outward from the roof at least two feet. The scaffold platform shall be provided with a safety railing constructed and installed in compliance with this Part (rule) and the space between the scaffold platform and the roof shall not be more than six inches.

4. (2) If such work does not extend to any roof edge, portable stanchions located five feet in from the roof edge and connected by ropes or chains shall be provided. Such stanchions shall be spaced so that the connecting ropes or chains shall not be less than 36 nor more than 48 inches above the roof surfaces.

   (d) Hot roofing material transporters, also known as hot luggers.

   Closed containers or devices used for transporting molten roofing materials from fill stations to the application areas on roofs shall be equipped with at least the following safety features in order to minimize hazards to persons caused by blowbacks of the molten roofing materials:

5. (1) Existing transporters. On or before January 1, 1973, every existing transporter shall be equipped with the following safety devices:

   1. (i) The fill pipe cover shall be provided with a safety latch designed and installed to keep the cover in place at all times except during filling operations.
   2. (ii) On top of every such transporter remote from the fill pipe there shall be installed an automatic venting device designed to release any accumulation of gas pressure. Such venting device shall be inspected daily to assure proper operation.

6. (2) New transporters. Every transporter manufactured after January 1, 1973 shall be equipped with the following safety devices:

   1. (i) The fill pipe cover shall be provided with a safety latch designed and installed to keep the cover in place at all times except during filling operations.
   2. (ii) Every such transporter shall be automatically vented or so constructed as to prevent the accumulation of gas. Every such transporter shall be inspected daily to assure proper operation.
   3. (iii) Manufacturers of hot roofing material transporters shall furnish written operating and safety instructions with every transporter.
