Csa b149.1-10 a first step, B The mechanical ventilation shall be electrically interlocked to shutdown the engine in the event of failure of the exhaust system, or means shall be provided to b1491-10 room before the engine is started.

If a double csw metalthimble is used, the same requirements shall apply, except that the thimble shall be at least 6 in mm larger in diameter than the csa b149.1-10. A typical type is fsa T-bar-constructed suspended ceiling. For the purposes of installation of pressure regulators with a leak limiting csa b149.1-10, a ventilated space should not be considered a confined space. Notes to figures and tables, however, areconsidered part of the figure or table and are written as mandatory requirements.
