Food Gas Mixture Cylinder

Cylinders are not hazardous cargo until they are taken into use, but in any case they should be transported in conditions that exclude mechanical damage. Cylinders filled with a food gas mixture shall be transported by all modes of transport in accordance with cargo carriage regulations applicable to this mode of transport, as well as safety rules for transportation of dangerous goods by rail. Cylinders may be transported in special containers, as well as without containers in an upright position, always with spacers between them and secured against possible falling. The cylinders must be transported with caps screwed on.

Cylinders designed for storage and transportation of the food gas mixture must not be used for storage and transportation of other gases, and it is prohibited to perform any operations that may contaminate their internal surface and degrade the physical and chemical properties of the gas. It is forbidden to make any modifications to the cylinder bodies using welding or mechanical tools, which can lead to damage to the integrity or appearance of defects that degrade the technical characteristics of the cylinders. When using cylinders for food gas mixture it is not allowed to install them in the places of people passage, movement of goods and passage of vehicles. Cylinders must be located at least 1 m away from radiators and other heating devices and at least 5 m from heat sources with open flame. Many components of food gas mixtures are themselves explosive and flammable substances, therefore premises with a potential risk of accumulation of these components must be provided with uninterrupted functioning ventilation. The gas in the cylinders must not be completely consumed when in use. The residual gas pressure in the cylinder must be at least 0.05 MPa (0.5 kgf/cm2).

Cylinders with a food gas mixture can be stored both in special rooms and in the open air, in the latter case they must be protected from atmospheric precipitation and sunlight. Cylinders filled with a food gas mixture may be stored in open areas together with other gases, provided that the storage areas are separated from each other by non-combustible barriers with a height of 1.5 m, joint storage with cylinders filled with combustible gases is also allowed, provided that the storage areas are separated from each other by non-combustible protective walls not less than 2.5 m high. Storage of cylinders should be carried out with the caps screwed on.
