![]() The primary objective is to prevent danger from unintentional release of stored energy. University guidance informs Schools/Departments of the key requirements for the safe operation and management of piped compressed gas systems attached to transportable gas cylinders and stand-alone transportable compressed gas cylinder installations (see related link to DRAFT guidance). is subject to specific regulation and special notification to the appropriate agency is required. Compressed air should be used with caution and never in the context of practical jokes.Īcetylene used at > 9 p.s.i. Oxygen is particularly dangerous since it is more likely to promote fires or explosions than is air. Wherever practicable all cylinders containing gas should be kept outside a building in a well-ventilated area. Cylinder valves must not be lubricated.Ĭylinders of compressed gases can be a hazard if fire breaks out. They should always be secured to prevent them being knocked over accidentally. Detailed information on this is contained in British Compressed Gases Association publications (CP4 and CP5 are particularly). In particular the materials from which any components of the system are made should be compatible with the gas being used. Gas cylinders should be handled gently and used only with the correct fittings. Do not store flammable gases near any source of ignition.Store in a safe place outside or in a room that has adequate ventilation.Wear suitable safety shoes when transporting cylinders. ![]() ![]() Transport cylinders in suitable trolleys with dust cowls in place.Ensure the cylinder is secured in a trolley or securely chained/strapped to the wall or bench.Use only brass spanners (these do not create sparks) when fitting regulators to cylinders of highly flammable gas.(Tepol/water can be used as vegetable based but soapy water must not be used as it is oil-based). Check for leaks using leak detection fluid - proprietary sprays are recommended.Do not use grease or PTFE tape on threads - this can present an explosion risk and indicates unsatisfactory seal being made which could leak.Wear a suitable face visor or safety glasses (to protect against impact) when changing/fitting regulators.Ensure the regulator and pipework is appropriate for the type of gas and pressure regime.No person should use a gas cylinder or change the cylinder regulator unless they have received appropriate training and are authorised to do so by their supervisor or line manager. Over-pressurisation in the event of fire.Fire due to escape of flammable gas/fluid.Oxygen is particularly dangerous as it can promote fires and explosion and sustains combustion. Exposure to released gas or fluid, which may have harmful properties (asphyxiant, toxic, corrosive).Explosion of the cylinder due to mechanical damage, weakness or over-pressurisation.Main hazards associated with compressed gases
