1.2.1 Casualty access techniques Direct boom access
In general , rescue services train staff to access the casualty in rescue platforms from above . This is to stop the person from jumping from their position to the platform . Whilst in an EWP rescue this is still the best possible situation , in tree rescues this is rarely possible .
There are two common scenarios :
1 . That the EWP cannot reach the casualty because of tree structures in the way .
2 . That the EWP can reach the casualty , but the casualty is suspended on their climbing system and will require some extrication .
1 . In the common occurrence that the EWP cannot reach the casualty it may be necessary to cut branches off to perform the rescue , making the tree less bulky and allowing for platform access . The following may be considered :
• Chainsaw trained personnel in basket . hold ”. Each section must be small enough to control comfortably . Workers continue to shorten each branch to gain access . This may need to be done below and above the injured worker .
• The limbs that are cut off are then thrown to the ground and not piled up on the platform .
• The area below the platform needs to be isolated and ensure that no persons can be hit by falling debris .
2 . Upon gaining access , the tree worker must be removed from their existing connection . This will commonly be either by a primary rope system , or by their flip line attaching directly to a limb . The worker will need to be lifted to free these systems , this can be done by means of a set of fours or mini hauler set up .
Caution here as the casualty should be attached to platform as a safeguard first !
• Chainsaw is secured to the basket via the rear handle to reduce the ‘ drop potential ’.
• The limbs are held by one crew member and cut in small pieces by the other , a technique called “ cut and
