Tips for safe use of gas cylinders:
Do not use dangerous means such as rope pulling to transport cylinders to high places, and do not use stairs or ramps to transport cylinders down freely.

Gas cylinder accessories, such as safety helmet, shock-proof ring, pressure gauge, pressure reducing valve, etc., should be fully qualified.
Combustible gas cylinders such as dissolved acetylene cylinders should also be equipped with anti-return firearms suitable for the type of gas. Different types of anti-return firearms should not be mixed

5、Flaw detection of the cylindrical parts：

The cylinder wall shall be examined for longitudinal imperfections with the ultrasonic energy transmitted in both circumferential directions and for transverse imperfections in both longitudinal directions. 

For concave-based cylinders where hydrogen embrittlement or stress corrosion can occur (see ISO 11114-1), the transition region between the cylindrical part and the cylinder base shall also be examined for transverse imperfections in the direction of the base.

6、Gas cylinder flaw detection shall be performed by one of the following two methods.

⎯ Method A: The ultrasonic sensitivity shall be set at + 6 dB in order to improve the detection of imperfections equivalent to 5 % of the cylindrical wall thickness in this thickened portion. 

⎯ Method B: The ultrasonic system shall be calibrated using a standard reference artefact of a cylinder with a notch at sidewall-to-base transition (SBT) area shown in Figure B.2. 

⎯ The depth of notch, T, for SBT shall be (10 ± 1) % of the guaranteed minimum wall thickness, a′, with a minimum of 0,2 mm and maximum of 1 mm, over the full length of the notch.
