6.1 Annual maintenance should be carried out by a person who has sufficient practical experience of oxyacetylene gas equipment and a
detailed theoretical knowledge of the functioning of the equipment, the properties of gases used and potential defects and hazards
which may occur and their importance to the integrity and safety of the equipment.
6.2 regulator elastomers and seals will wear and deteriorate in service and will also deteriorate out of service. regulators stored for 1
year or over without use should receive inspection as per the annual maintenance schedule.
