Answer 1

Safe route and siting
Possibility of acetylene 
Use of overlay
Surrounding risks
RVP
Any additional info

Question 2

Initial actions ID

Answer 2

If involved
Type 
Contents
Size 
Number
Location

Question 3

DRA

Answer 3

If can confirm;
1/ fire extinguished
2/ cylinder not acetylene 
3/All located
4/ All receiving direct cooling
Then only need cordon to maintain SSOW. If not then full cylinder proc.

Question 4

Composite

Answer 4

Allow contents to burn off and protect surrounding risks and gas dispersal.

If resin still intact extinguish fire and cool cylinder.

If can’t confirm composite, it may have aluminium liner, there treat as steel cylinder.

Question 5

Steel Cylinder

Answer 5

•If risk failure (300 oC) 200m HZ. Substantial cover may allow reduction.
Consider time to implement this against time to cool cylinder.

• If not risk failure just need size HZ to allow SSOW.

•Extinguish Fire & cool cylinder to ambient temp as assessed by TIC, and check not leaking ( sound of air escaping or bubbling). Then remove HZ..
Send message stating highest temp and HZ removed, TM.

Question 6

Acetylene

Answer 6

•200m HZ
•Cool 1hr
•CAP - TIC, steaming drying out, leave 15 mins,spray water.
Do this 4 X = 1hr.
• HMEPO can advise on reducing HZ after 1st successful test in CAP
• If not ambient temp reapply 1hr cooling and CAP
•If cylinder is at ambient temp it is not at risk of failure providing;
1/ not reheated
2/ not moved or disturbed during CAP
3/ cooled & monitor until CAP passed
• If passed hand over to RP

Question 7

HMEPO at Acetylene Inc.

Answer 7

Must maintain log and record;
1/ cylinder location 
2/ time cooling start & finish
3/time of CAP and temp readings
4/ All decisions during cooling
5/ If Req. CP and their advice.

Log must be handed to subsequent HMEPO or IC if not available. Final one must send it back to initial HMEPO.

Question 8

Cylinder alight at valve group

Answer 8

If heated it should be cooled bring careful not to ext flame.

Question 9

Leaking cylinder

Answer 9

• Treat as hazmat
• close valve if possible
• If not monitor atmosphere
• Consider RRT, FRU, HMEPO

Question 10

Assistance

Answer 10

HMEPO can consult BCGA and SA.
CP can advise on;
1/ no of cylinders delivered to property
2/support decision making
3/ arrange to collect at end.

Question 11

Hazard zone management.

Answer 11

• can only work in HZ following RA by IC & HMEPO.
• IC in consult with HMEPO decide size.
• significant infrastructure routes left open only if substantial cover maintain safety.

Question 12

Evac public

Answer 12

Can remain indoors If 100m away in HZ or those refusing to leave.

If refusing to leave pass details onto police.
