Section 59: Air receivers

59. Air receivers (1) Every air receiver and every part thereof and all its fittings shall be of good construction, sound material, adequate strength and free from patent defect, and shall be properly maintained. (2) Every air receiver shall— (a) have marked upon it, so as to be clearly visible, the safe working pressure; (b) in the case of a receiver connected with an air compressing plant, either be so constructed as to withstand with safety the maximum pressure which can be obtained in the compressor, or be fitted with a suitable reducing valve or other suitable appliance to prevent the safe working pressure of the receiver being exceeded; (c) be fitted with a suitable safety valve so adjusted as to permit the air to escape as soon as the safe working pressure is exceeded; [Issue 1] O2 – 42 Revised Laws of Mauritius (d) be fitted with an accurate pressure gauge indicating the pressure in the receiver and have marked on the face of the gauge in a distinctive colour the safe working pressure; (e) be fitted with a suitable appliance for draining the receiver other than a vessel specified in paragraphs (b) and (d) in the definition of “air receiver”; (f) be provided with a suitable manhole, hand hole or other means which will allow the interior to be thoroughly cleaned; and (g) where there is more than one receiver in use in the place of work, bear a distinguishing mark which shall be easily visible. (3) For the purpose of subsection (2), relating to safety valves and pressure gauges, any set of air receivers supplied with air through a single pipe may be treated as one receiver but in the case where a suitable reducing valve or other suitable appliance to prevent the safe working pressure being exceeded is required to be fitted, this subsection shall not apply unless the valve or appliance is fitted on the said single pipe. (4) Every air receiver shall be thoroughly cleaned and examined at least once every 12 months except that in the case of a receiver of solid drawn construction if it is so constructed that the internal surface cannot be thoroughly examined, a suitable hydraulic test of the receiver shall be carried out in lieu of internal examination at least once every 24 months. (5) Every examination and test specified in subsection (4) shall be carried out by a registered machinery inspector and the original report of the result of every such examination and test in the form set out in the Eighth Schedule shall be sent by the owner to the Director, Occupational Safety and Health within 28 days of the completion of the examination.
