Propane Tank Hazards – Unsafe Usage Lookout
OSHA recently issued a Hazard Information Bulletin to its compliance officers (inspectors) to be “on the lookout for unsafe use of LP-gas containers.” OSHA distributes Hazard Information Bulletins to all area offices and state plan offices, in addition to labor and industry associations.
The bulletin is notifying readers that propane tanks commonly found on construction sites may have regulators that extend outside the protective collars designed to prevent damage to valves. Extending regulators beyond the protective collar causes the regulator and attached equipment to be vulnerable if the tank falls, is dropped, are struck by a heavy object.
OSHA reported a case where a worker entered a confined space to clear ice from a manhole using a blowtorch with a regulator that was attached outside the collar of a 20-pound propane cylinder. The cylinder fell, the exposed regulator broke off, and gas and liquid propane released into the manhole. The propane caught fire inside the space and the worker burned to death.
The bulletin is likely to cause compliance officers to specifically look for this hazard during an OSHA inspection.
According to OSHA, workers using gas cylinders with unguarded regulators “appears” to be a common practice found on construction sites. OSHA standard 1926.153 addresses the use of liquefied petroleum (LP) gas containers. It requires you to protect normal 20-pound LP-gas containers from damage while in use or in storage. OSHA also reminds readers that LP-gas cylinders are covered by the National Fire Protection Association’s (NFPA) “Standard for the Storage and Handling of Liquefied Petroleum Gases,” 58-1995, section 2-2.4.1.
OSHA warns construction workers and employees of the hazards associated with unguarded regulators on propane cylinders, and that the standards require employees to receive training on how to do their jobs safely. The NFPA which sets voluntary safety standards also has recommendations covering protection for valves and connections such as regulators.
In short, make sure that your cylinders do not have attached regulators extending outside the confines of the protective collar, and that all critical parts of the equipment are protected from danger/damage. Supervisors should be familiar with the OSHA standard, safe use of the equipment, and most importantly – assure that all workers using/handling cylinders are properly trained.
