Oxygen enrichment can increase the risk of fires and explosions if not handled properly. Oxygen is heavier than air and can cause materials not normally flammable in air to burn fiercely. Any oils, greases or other contaminants should never be used with oxygen equipment as they can spontaneously ignite. Proper equipment should be leak tested and free of damage or contaminants, and flashback arrestors should be used, to safely manage the risks of oxygen enrichment.

- 1. Professionalism ▪ Integrity ▪ Trust ▪ Team Spirit Oxygen Enrichment Oxygen is a colourless, odourless and tasteless gas and makes up to 21% of the air we breathe, it has a relative density of 1.1 which means it is slightly heavier than air. Oils, greases, solvents and PTFE tape may react violently with oxygen. You should never use oil or grease to lubricate oxygen or oxygen enriched equipment as they can spontaneously burn with explosive violence. Dangers of Oxygen Enrichment If the atmosphere is enriched with oxygen the potential for fires is increased. Materials not normally combustible in air, will burn fiercely in an oxygen enriched atmosphere. They can also be ignited with minimum energy sources that would not, in air, be considered sufficient. If clothing becomes contaminated with oxygen, then quickly ventilate it by walking in fresh open air for at least 15 minutes, taking care to stay away from sources of ignition. For example, overalls treated to be 'flame-retardant' can, in an oxygen enriched atmosphere, burn vigorously. Oxy-Gas Equipment Never use regulators, hoses, cylinders or torches or any other oxy-fuel equipment if Oil, grease or similar contaminants are present, or the equipment shows sign of damage. If using cylinders in an enclosed area leak test the high pressure connection between the regulator and the cylinder valve using an approved leak test solution. Do not use soapy water as soap contains oils Never use lubricants, PTFE or other jointing compounds to obtain a seal. Faulty equipment must not be used. Flashback arrestors should be fitted to all fuel gas supply lines and to oxygen supply lines when they are used in conjunction with fuel gases. Remember Oxygen is invisible...! It is silent...! It has no smell...! & it helps to burn fiercely...! Toolbox Talk
