Cylinder procedure

Question 1

Cylinder Hazards?

Answer 1

• Projection upto 200m
• Fireball upto 25m in diameter - BA, Full PPE.
• Look for Hazmat signs
• Confirm involvement and type of cylinder
• Hazard zone overlay

Question 2

If not acetylene and cylinders being cooled to ambient temperature, what should the hazard zone be?

Answer 2

Advice sort from the HMEPO/SA or a representative from British Compressed Gas Association as to reducing the hazard zone to 25m.

Send message stating highest recorded temperature taken by TIC and Tac mode.

Question 3

Non acetylene cylinders action taken?

Answer 3

Cool to ambient temperature and then handover over to responsible persons. Fill out handing over form.

Question 4

Actions on discovering acetylene cylinders involved?

Answer 4

CAP TEST

• Hazard zone of 200m
• Cool for 1 hour then record temp with TIC
• Observe for rapid drying out/violent steaming on surface.
• No water for 15mins.
• Apply momentary spray to cinder, check for steaming.
• Repeat above x 4.

HMEPO can reduce hazard zone if round 1 of CAP test is successful, but remaining 3 rounds must be completed.
