Q

** Composite cylinders are most commonly used for domestic purposes such as BBQs. What happens if a composite cylinder fails?

A

Intensifies the fire

22
Q

Is the Hazard Zone the same as the Exclusion Zone?

A

No

23
Q

What should Message include? (5)

A

…. x ….. kg ………… cylinders involved, cylinder procedure being implemented, RVP

24
Q

What is the Cylinder Assessment Procedure?

A

Stop cooling after 1 hour
Monitor with TIC & record Temperature
Look for Violent Steaming
Leave for 15 minutes
Apply momentary spray and repeat x 4 (total of 1 hour)
If it fails at any time reapply cooling Jet for 1 hour and start again.

25
Q

After the 1st CAP test who can reduce the HZ and why?

A

The HMEPO to carry out URGENT fire service work but 3 more tests must be completed.

26
Q

What is Aircooling?

A

Cylinder left to stand (requires more frequent CAP tests

27
Q

Does steam off a cylinder always indicate a problem?

A

No, on a warm day compare to other metal surfaces

28
Q

If a ‘Hot spot’ is identified during CAP process what should be done?

40
Q

What might a cylinder key be used for?

A

To shut of a cylinder alight at the valve group

41
Q

Can mechanical shock to an Acetylene cylinder start decomposition?

A

No, but it can make it worse

42
Q

Is a leaking cylinder not involved in fire a hazmats incident?

A

Yes

Q

Who carries atmospheric monitoring equipment?

A

RRT (Rapid Response Team) and FRU. DIM

44
Q

What are the 3 ways that you can identify an Acetylene cylinder?

A

Maroon colour
Identifying collar
Reflective Tape

45
Q

What is different in the marking of an Acetylene cylinder?

A

The whole cylinder is Maroon in colour

46
Q

The 200m exclusion zone for an Acetylene cylinder is maintained until there is no immediate danger of the cylinder failing provided that: (3)

A

A) the cylinder is not reheated
B) the cylinder is not moved or disturbed during CAP
C) cooling or monitoring of the cylinder continues until the cylinder passes CAP.

47
Q

Priority will be given to which members of the public once the HZ has been established?

A

A

Hazard Zone Coordinator

50
Q

On the unexpected discovery of a dangerous cylinder should appliances and equipment be moved from the HZ?

A
