rEnsure air is monitored where required (including CBRN).
OperatiOnaL cOnSiDeratiOnS rAll crews to book in and out of restricted area. rEnsure area is as noise-free as possible. rPerform initial line and hail sweep. rPerform hasty acoustic / seismic search / deploy canines. rCo-ordinate calls for silence between crews. rEnsure voids are adequately mapped. rGet victim hit clarified by other search means. rDivide search area into mapping grid. rPerform thorough seismic / acoustic / audio-visual searches.

15 ASR Levels
ASR LEVEL 3: RAPID SEARCH AND RESCUEConducted in the early stages of an incident.
r USAR teams appointed to worksite(s). r Rescue commitment comprising of debris removal, shoring, and limited breaching and breaking. r Limited penetration into structure/debris pile, with most rescue operations completed within hours. r Identify worksites requiring Level 4 operations (which may happen concurrently if resources are available).
ASR LEVEL 4: FULL SEARCH AND RESCUE r Identify, locate and rescue heavily trapped casualties. r Penetration into the most accessible survivable voids. r Extensive technical search, shoring, lifting and moving and breaching and breaking operations. r Possible confined space working. r Inter-agency cooperation.
ASR LEVEL 5: TOTAL SEARCH AND RECOVERYMoving from rescue to recovery and transfer of responsibility.
r Transition must be given serious consideration. r Delamination of the debris pile/structure to confirm no live casualties and to recover the deceased. r Searches repeated as delamination occurs. r May require heavy machinery, cranes etc. r Close liaison with structural/demolition engineers required. r Maintain minimum numbers of personnel in the risk area.

LOaDS On a DeViatiOn pOint
When a line deviates by an angle A, the load on the deviation point is given by the line tension T multiplied by the deviation factor D.
The line tension T is equal to M as it can slide freely through the deviation, so:-
F = M × D
e.g. if A = 45° and M = 100kg, the deviation load F = 75kg
For lifting and moving always keep the deviation angle A below 90°.
If the deviation has high friction and the rope is moving in either direction, F will be up to twice as high as the above figures indicate.
T=MAF
