Top 10 Tips for Safely Handling and Using Gas Cylinders

Not every one needs to know that fluorine will violently ignite many substances, that silane burns on contact with air, or that ammonia will decompose thermally into twice its volume. But if you work with specialty gases, this information is essential. Safety must always be a primary goal when working with specialty gases -safety and knowledge go hand-in-hand. To improve your chances of preventing hazardous accidents, follow these Top 10 Tips for safely handling and using gas cylinders: 1. Appropriate firefighting, personnel safety and first aid equipment should always be available in case of emergencies. Ensure adequate personnel are trained in the use of this equipment. 2. Obtain a copy of the MSDS for the gases being used. Read the MSDS thoroughly and become familiar with the gas properties and hazards prior to use. 3. Follow all federal, state and local regulations concerning the storage of compressed gas cylinders. Store gas cylinders in a ventilated and well lit area away from combustible materials. Separate gases by type and store in assigned locations that can be readily identified. Store cylinders containing flammable gases separately from oxygen cylinders and other oxidants by a fire-resistant barrier (having a fire-resistance rating of at least 30 minutes) or locate them at least 20 feet apart from each other. Store poison, cryogenic and inert gases separately. If a cylinder's contents are not clearly identified by the proper cylinder markings labels, do NOT accept for use. 4. Storage areas should be located away from sources of excess heat, open flame or ignition, and not located in closed or sub-surface areas. The area should be dry, cool and well ventilated. Outdoor storage should be above grade, dry and protected from the extremes of weather. While in storage, cylinder valve protection caps MUST be firmly in place. 5. Arrange the cylinder storage area so that old stock is used first. Empty cylinders should be stored separately and identified with clear markings. Return empty cylinders promptly. Some pressure should be left in a depleted cylinder to prevent air suck-back that would allow moisture and contaminants to enter the cylinder 6. Do not apply any heating device that will heat any part of a cylinder above 125
