DELSAR

Can you connect seismic and acoustic sensors at the same time?
No, this will cause errratic operation.
DELSAR

Detail the pre use test?
Connect all sensors and place in a 1m2 square.
Tap the centre of the square and observe the display, check each sensor individually.
Run out a sensor 10m and check operation and move in if needed depending on substrate
Check both sets of headphones are working.
Operator should listen to background noise for 5 mins, where possible.

DELSAR

How do you select an individual sensor?
Select the required sensors corresponding number on the display graph.
DELSAR

The microphones are live by default, how do you mute them?
Simultaneously press headphone L-R and the PPT button, this will cause the LED to flash, indicating the mics are muted
DELSAR

How do you record whilst using the unit?
Press record. This will start the 5min, continuous recording loop.
DELSAR

How and when do you use the zoom function?
When the victim is located, press zoom and this will further enhance the sensors, thus making sensor comparisons easier.
DELSAR

What are the 2 main phases of search techniques?
Detection stage 1 and 2
(Hasty search & Operational sweep)
Location
DELSAR

What are the 2 stages of the detection phase and how are they carried out?
Hasty search: connect 1 or 2 sensors, place on large areas and shout for victims to tap, cover whole site.

Operational sweep: Thorough search using all sensors and mapping and planning. On detection of victim go to location phase, get second team to continue rest of search.
Delsar

What are the horizontal and vertical limits of the Delsar?
10 x 30 m depending on substrate
DELSAR

What special points should be remembered when using Delsar?
If one sensor is placed on its side, inform operator as all sensors should be placed the same way.
Cover sensors in the rain
Manage cables and protect from wind noise and movement.
Delsar

What percentage of sensor efficiency is lost when placed on it's side?
30% CHECK THIS
Lukas

What is the operating pressure of the Lukas equipment?

500bar
Lukas

What must be remembered when using the ram?
The first extension is not under pressure until the 2nd stage and may fall from position?
Lukas

What must be remembered when connecting and disconnecting the hose?
Connect blue first and disconnect last.
Lukas

Approximately how long will the petrol power pack last on a full tank?
2hrs
Lukas

What generates the power for the electric power pack?

Grey: 2 extensions up to 900mm  (3ft)
Gold: 1 extension up to 1.8m  (6ft)
Shoring

Can you mix Gold and Grey?
Yes, in the same shore but not in the same strut.
Shoring

What should the measurement of a header and footer be in a two post vertical?
When it fits, 7ft. 
18inch max overhang, this allows for bracing
min 12inch overhang
(4ft between struts)
Shoring

Describe a sloping floor shore, Perpendicular.

The struts are 90 degrees to the header
Use swivel base plates
Shoring

Describe a sloping floor shore, friction.
The load is not pinned at one end,

Use swivel bases on the header
Shoring

What are limitations of a four point crib stack?
Can't be more than 1m tall
Each point will support 1.25 tonnes
Max load for crib is 5 tonnes
The slope of the supported structure can't exceed 5% or 50mm in 1m
Use a solid base on soft ground or top for work platform

Shoring

Shoring

What is the insertion point height for a raker shore?
As close as possible to where the floor intersects the wall or up to two foot below but not above.
Shoring

What is the maximum distance you should be from any shore?
4ft
Shoring

How many floors below should shoring ops begin?
Timber: 1 floor (consider load on floor)
Concrete: 2 floors below (consider load on floor)
Shoring

What is the maximum distance between raker shores?
2.4 m  (8ft)
Shoring

How often should raker shores be braced?
1st, last and every 32-40 feet or 4th shore
Shoring

How can you calculate the length of strut for a raker shore?
