The construction of all industrial gas cylinders supplied by Afrox is in accordance with specifications approved by the Chief Inspector of Factories.
Cylinders are colour-coded in accordance with SABS specifications and each cylinder is clearly marked with the name of the gas it contains. Customers should not accept delivery of any gas cylinder which is not immediately and positively identifiable.
To prevent the interchange of fittings between cylinders of flammable and non-flammable gases, the valve outlets are screwed left hand and right hand respectively.
Only Afrox, or their specially authorised agents, are permitted to fill the company's cylinders.
Never attempt to decant gas from one cylinder to another.
Never allow cylinders, their colour, valve threads or markings to be altered in any way.
