• 2.17 (1) Subject to subsection (2), where a high-capacity portable open-flame heating device is used in an enclosed work place, the heating device shall

  • (b) be used only when there is ventilation provided;

  • (c) be located so as to be protected from accidental contact, damage or overturning; and

  • (d) not restrict a means of exit.

• (2) Where the heating device does not provide complete combustion of the fuel used in connection with it, it shall be equipped with an exhaust system that discharges the products of combustion outside the enclosed work place.

• 2.18 (1) No employee shall climb a tower, an antenna or an antenna-supporting structure unless

  • (a) the employer has authorized the employee to do so;

  • (b) the employee has been trained and instructed in a safe method of climbing; and

  • (c) the employer has provided a fall-protection system in accordance with section 12.10.

  • (a) when weather conditions are likely to be hazardous to the health or safety of the employee, except when the work is required to remove a hazard or to rescue an employee; or

  • (b) if the physical condition of the tower, antenna or antenna-supporting structure is likely to be hazardous to the health or safety of the employee.

2.19 Where reasonably practicable, the design and construction of every tower, antenna and antenna-supporting structure the construction of which begins on or after the day of the coming into force of this section shall meet the requirements of CSA Standard CAN/CSA-S37-94, entitled Antennas, Towers, and Antenna-Supporting Structures, as amended from time to time.
