Some compressed gases pose special problems. Fuel gases in general are dangerous because they burn, but other gases can be hazardous for other reasons. Knowing the potential problems associated with each type is very important.

This second chapter discusses procedures that should be followed during hauling and use of some of these special gases, and reviews the causes and cures of flashbacks and backfires, storage procedures, manifolding, and caring for hoses and fittings. The first chapter outlined general rules for safe handling of compressed gases and their cylinders and regulators.
