Woikoski gas cylinders can be identified by the stamps on the shoulder part of the cylinder, labels and the color of the cylinders. Identification markings on gas cylinders are based on different regulations.
The stamps on the shoulder part of cylinders are the main identification criterion. The name of the gas is always stamped on the shoulder part of the gas cylinder. The markings also tell about the inspections, manufacturer, weight, pressure and volume of the cylinder. The markings are in accordance with the standard SFS-EN 13769.
The coloring of Woikoski gas cylinders is carried out in accordance with standard EN 1089-3. According to it, the cylindrical part of gas cylinders is white for medical gases and graphite gray for industrial gases (excluding acetylene and LPG).
The shoulder of the gas cylinders indicates the type of gas in the bottle. Some of the gases are assigned their own identification color.
| acetylene - oxide red, RAL 3009 | |
| helium - olive brown, RAL 8008 | |
| oxygen - pure white, RAL 9010 | |
| nitrous oxide - gentian blue, RAL 5010 | |
| argon - emerald green, RAL 6001 | |
| nitrogen - jet black, RAL 9005 | |
| carbon dioxide - dusty grey, RAL 7037 |
The cylindrical part of the gas cylinder for industrial oxygen is graphite gray and white for medicinal oxygen. The shoulder parts of the gas bottles are painted white, which indicates that they contain oxygen.
If the gas does not have a signature color, the color of the shoulder part indicates the properties of the gas:
| toxic - yellow, RAL 1018 | |
| flammable - red, RAL 3000 | |
| oxidizing - light blue, RAL 5012 | |
| inert - bright green, RAL 6016 |
Mixed gases may have several colors on the shoulder part of the cylinder, depending on the gases. If the concentration of the gases is the same, punching and painting are done in the pre-agreed order. A neck ring can be used as an additional identifier (e.g. gas purity, special field of use, etc.).
The most essential label for gas identification is the so-called wing sticker with the name of the gas, possible trade name, composition (mixtures), safety instructions, classification markings and contact information of the gas supplier. The base color of the medical gas wing sticker is white, yellow for industrial and green for food gas. The information content of the wing sticker is based on the SFS-EN ISO 7225 standard.
