This presentation summarizes a training on compressed gas cylinder safety. It contains photos submitted by Rafael Coll of unsafe cylinder storage and use examples. Trainees have found the "what is wrong with this picture" segment to be the most helpful part of the training. Coll invites others to submit additional unsafe photos for inclusion.

1. For the user of this presentation:

Author uses this presentation for Compressed Gas Cylinder Training
During the “what is wrong with this picture” segment. Trainees have
rated this segment as the best part of the training.
If you have other photos you care to submit, send them directly to
rcoll@fnal.gov with a note as to what is wrong in the photo.
I will continue adding to this presentation and posting to the
Vermont SIRI.

37. An Ironworker crew was modifying a temporary structural steel bridge
using an Oxygen/Acetylene torch setup on a cart, a portable welder,
and a grinder. Apparently the Acetylene hose developed a leak and
ignited during the grinding operation ( Monday June 18, 2001 )
Compressed Gas

38. The torch setup was not equipped with a “flashback” arrestor
check valve and the fire traveled through the hose into the
compressed cylinder.
All Oxygen/Acetylene setups must
have a “Flashback” arrestor check
valve at the regulators, NOT the
torch head, to prevent this type
of occurrence. This little device would
have prevented this fire.
