This standard covers the accessing of trees through climbing (both ladders and using climbing equipment) and by Mobile Elevated Work Platform (MEWP) to carry out rescues in a variety of contexts (pruning operation, cutting, dismantle or rigging). The aerial rescues include recovery of both conscious and unconscious casualties. When carrying out aerial rescue you must maintain high standards of health and safety at all time for both yourself and the people you will come into contact with. This standard is for those carrying out aerial rescue operations. Your work must conform to all current legislation and codes of practice.Cross-cutting operations will include cross-cutting timber under tension in the form of fallen branches, tops, tree sections, severed uprooted stems, horizontal stems, or any timber in a similar situation. This describes the cross-cutting of trees or timber into either manageable sections or to a given length and diameter specification, either where trees have been felled (“at stump”), or at a conversion point to where trees or timber have been extracted. Cross-cutting operations are often carried out in conjunction with the snedding or de-limbing process. Timber under low and moderate tension is covered, but not timber under the extreme tensions found in e.g. windblown trees. The severing of root-plates is excluded.
If you are working with chemicals or machinery you need to be appropriately trained or certificated in line with current legislation. This standard is for those using chainsaws.
