Inspected Monthly & Annually Training for Designated Employees (i.e. fire watch) Hazards Associated w/ Compressed Gases • Fire • Oxygen Enriched • Mixed Gases • Explosion: Flying Projectile • Damage to Cylinder • Cylinders High & Low Pressure • Release of Gas • Displacement of Oxygen ( CSE ) • Toxic Gases • Cryogenic Acetylene cylinders Fusible Plug .. Porous Mass Acetone Solvent 42% Fusible Plug The decomposition characteristics of acetylene gas are avoided: • By providing a porous mass packing material with minute cellular spaces • No pockets of appreciable size remain where “free” acetylene in gaseous form can collect • This porous mass is saturated with acetone, or other suitable solvent, in which the gaseous acetylene actually dissolves Volume . . • CANNOT store on side- Leak around valve stem 3.5 Flammable Gases Indoor cylinder storage • • • • Fuel Gas Well protected Well ventilated Dry Twenty feet from flammable or combustible materials 20 Feet O x y g e n • Ready to go? • Storage?

Some sources of ignition include: • • • • • • • Open flames Smoking Static electricity Cutting and welding Hot surfaces Electrical and mechanical sparks Lightning Static Electricity • Generated when a fluid flows through a pipe or from an opening into a tank • Main hazards are fire and explosion from sparks containing enough energy to ignite flammable vapors • Bonding or grounding of flammable liquid containers is necessary to prevent static electricity from causing a spark Storage Rooms 4” Sill or ramp at Door Self Closing Fire Rated Door Always provide adequate ventilation to reduce the potential for ignition of flammable vapors. • Gravity • Mechanical • 6 Air Changes Per Hour Safety Cans for Storage and Transfer • Approved container of not more than 5 gallons capacity • Spring-closing lid and spout cover • Safely relieves internal pressure when exposed to fire Flame Arrester Screen • Prevents fire flashback into can contents • Double wire-mesh construction • Large surface area provides rapid dissipation of heat from fire so that vapor temperature inside can remains below ignition point Waste and Residue Combustible waste and residue must be kept to a minimum, stored in covered metal receptacles and disposed of daily.

EXIT ACCESS Disclaimer • This information has been developed by an OSHA Compliance Assistance Specialist and is intended to assist employers, workers, and others as they strive to improve workplace health and safety. While we attempt to thoroughly address specific topics or hazards, it is not possible to include discussion of everything necessary to ensure a healthy and safe working environment in a presentation of this nature. Thus, this information must be understood as a tool for addressing workplace hazards, rather than an exhaustive statement of an employer’s legal obligations, which are defined by statute, regulations, and standards. Likewise, to the extent that this information references practices or procedures that may enhance health or safety, but which are not required by a statute, regulation, or standard, it cannot, and does not, create additional legal obligations. Finally, over time, OSHA may modify rules and interpretations in light of new technology, information, or circumstances; to keep apprised of such developments, or to review information on a wide range of occupational safety and health topics, you can visit OSHA’s website at www.osha.gov.
