Safety advisory notice.
Summary
RSPA is alerting persons who own, use or are responsible for the maintenance of composite cylinders to a hazard. Damage may occur when a composite cylinder comes in contact with strong cleaners or other strong corrosive agents. RSPA is aware of ruptures involving two DOT-E 8059 composite cylinders made with aluminum liners and wrapped with ``S glass'' fibers. The probable cause of both cylinder failures was stress-corrosion cracking of the fiberglass overwraps as a result of exposure to a strong corrosive agent.
