Yes Personnel who use gas cylinders do not need to obtain the certificate of special equipment operators. In the categories and projects of special equipment operators, cylinder operation refers to: permanent cylinder filling, liquefied gas cylinder filling, dissolved acetylene cylinder filling, liquefied petroleum gas cylinder filling and automobile cylinder filling. It is correct that users of gas cylinders do not need training. If the warehouse keeper is responsible for the daily safety management of gas cylinders, he shall obtain the certificate of special equipment operator, and the operation project shall be the safety management of boiler, pressure vessel and pressure pipeline.
