1910.253(b)(4)(iii) "...30 minute rating." Cylinder Storage

By Airdale Date 08-10-2011 15:07

Hey guys,
One of our clients just got bagged by OSHA for not having a barrier having a thirty minute rating between oxygen and fuel gas cylinders in a storage rack. I had always thought that a steel plate, 1/4" thick constituted such a barrier. What is your experience with this? Is there anything in the literature stating what materials constitute a thirty minute barrier?

Thanks,

Jim Feeny

Hi Jim,
My guess is that NFPA (National Fire Protection Agency) is the governing code for safe storage distances and barriers.

Try NFPA 51 to see if it has the guidelines for this.

Was the plate
5' tall?
1910.253(b)(4)(iii)
Oxygen cylinders in storage shall be separated from fuel-gas cylinders or combustible materials (especially oil or grease), a minimum distance of 20 feet (6.1 m) or by a noncombustible barrier at least 5 feet (1.5 m) high having a fire-resistance rating of at least one-half hour.
