Regulators are designed to fit only specific cylinder valves to avoid improper use. Secure cylinders by chaining or strapping them to a wall, lab bench, or other fixed support. Do not use oil or grease on any cylinder component of oxidizing gas, because a fire or explosion can result. Be careful while handling compressed gas cylinders and never drop or bang a cylinder against anything. Use only wrenches or other tools supplied by a cylinder manufacturer to open a valve.
Open cylinder valves slowly.
Place all cylinders so that the main valve is always accessible. Use toxic, flammable, or reactive gases only in a fumehood. Storage Close the main cylinder valve when the cylinder is not in use. Remove regulators from unused cylinders and put the safety cap in place to protect the valve. Never completely empty cylinders, leave approximately 25 psi remaining.
