SA/HMEPO

18
Q

A

25 litres. This may be difficult to determine so it is always prudent to inform EA if you are unsure

20
Q

Why should at larger incidents of mercury spillage (perhaps from a barometer rather than a thermometer) should the IC request a HMEPO before requesting additional resources?

A

As often the complexity of recovery rather than the quantities involved will dictate the resources requirement

21

A

No. Level 4 is a specific attendance agreed prior to the mobilisation of any resources

22
Q

What is the APP code?

A

1 x PL (wm)

1 x P

1 x HMEPO

1 x RRT

This is so the nearest appliance is mobilised to give immediate and constant supply of water. Min 20 or until medical assistance arrives

24
Q

Describe the hazard zone?

A

The area that contains hazard to which a risk assessment should be applied. Other agency may refer to it as evacuation zone and an area where they would seek to encourage all members of public to leave.

25
Q

Where is the decontamination zone?

A

Out side the inner zone which becomes contaminated by the managed and controlled movement of people who require decontamination

26
Q

What is the PDA of level 2 hazmat ?

A

2 pumping appliances
And FRU (for decontamination)
HMEPO and monitoring officer to advise

27
Q

Level 3

A 
Additional 2 pumping appliances 
FRU for DIM
Scientific support unit
The monitoring officer from level 2 (SM) who should take charge 
Group manager for monitoring

If additional is required this does not make it a level 4

28
Q

Level 4 incidents are what?

A

Defined as incident attracting special mobilising criteria and not necessary large attendance. PDA determined by brigade with advice from the duty ILO and HMEPO

Q

Where and how do you get a Hughes shower?

A

They are on IRU and not any PDA! Apart from mass decontamination.

When requested come with a support pump

30
Q

Does deployment of DIM crews and equipment make it a confirmed hazmat incident?

A

No. That decision rests with the IC

But appropriate Decon should be in place before crews are committed

31
Q

If the hazmat is unknown can the IC commit a crew with out GTS but in BA and full PPE to make a rescue?

A

After DRA and for saveable life. If the time donning GTS would result in loss of live.

Should stay under air until get advice from HMEPO/SA

A

Hazard are limited and decon be achieved with either dam and brush or safe or undress

Can include explosive hazards
Refrigerant leak domestic
Domestic cleaning products

PDA

1 PL
1 P
1 FRU (for decon)
1 OSU (on request only)

For railways 1 PL secondary location

36
Q

Level 3 hazmat incident are defined as?

What’s the PDA?

A

Large hazmat incident where additional resources are required to deal with the incident or decontaminate using the Hughes shower

PDA
