PART XXIX UNDERGROUND OPERATIONS — Reciprocating type air compressors
571
(1) In an underground place of employment, a reciprocating type air compressor driven by a prime mover exceeding 30 kW, that is lubricated by oil and discharges to a closed system at a pressure greater than 100 kPa, shall have
571(a)
a temperature-indicating device installed at the high-pressure discharge pipe; and read by a qualified person at least once every operating shift; and designed and installed to minimize the hazard of fire or explosion due to the accumulation of carbonaceous materials in the air system;
571(b)
the normal operating temperature marked on the device. recorded in a compressor log book maintained by the employer. provided with protective devices that prevent its operation where
571(2)
The discharge air temperature of an air compressor referred to in subsection (1) shall be
571(3)
Subsection (2) does not apply where an automated, continuous monitoring system designed to be fail safe has been installed.
571(4)
Where an air compressor driven by a prime mover exceeding 25 kW is installed in an underground place of employment, the compressor shall be
571(i)
the temperature of the air at the discharge line is in excess of normal, (ii) the temperature of the compressor cooling water and cooling air is in excess of normal, (iii) the flow and pressure of compressor lubricating oil is below normal, or (iv) carbon monoxide content of compressed air between the high pressure discharge and receiver exceeds 25 ppm; is audible and visible to the worker in charge of the compressor, (ii) operates when a protective device referred to in paragraph (b) is activated, and (iii) operates as long as the conditions exist that direct a device as referred to in paragraph (b) to operate; and
