0039-22: Tree Climbing and Aerial Rescue Flashcards
5 Steps.
Explain the risk assesment process.
Climbing
- Identify the hazard
- Decide who might be harmed and how.
- Evaluate the risks and decide on precausions
- Record the fidings and impliment them.
- Review and update the assesment as necessary
Outline emergency
planning relevant to
the working area
(EAP)
Emergency planning relevant to a work site may include:
* site location
* grid reference
* what three words
* designated meeting place
* nearest access point
* street name/district
* type of access (public road/light vehicles, four-wheel
drive)
* suitable helicopter landing area
* phone number of nearest doctors
* location of nearest accident and emergency hospital and phone number
* works manager contact details
* your own contact number/mobile number
Outline responsibilities as an operator under the following
- H.A.S.W.A
- L.O.L.E.R
- P.P.E
Outline key points from the legislation listed below:
Health and Safety at Work Act (HASWA):
*correct and appropriate train has been received
* employers responsibility for employees
* employees responsibility for themselves and others such as pedestrians.
* other
Operator’s responsibility under Lifting Operations and Lifting Equipment Regulations (LOLER) regulations may
include:
* equipment should be subject to a pre use check by the climber
* a recorded interim inspection should be kept for equipment subject to high levels of wear
Operator’s responsibility under the Personal Protective Equipment (PPE) regulations may
include:
* carry out equipment maintenance as per manufactures guidance
* correct storage of PPE
State key point from
the work at height
regulations
- can you AVOID working at height in the first place?
- can you PREVENT the fall from occuring?
- can you MINIMISE the distance and/or consiquences of a fall?
- using stepladders or ladders.
State industry guide relevant to tree climbing and aerial rescue
Industry guides relevant to Tree climbing and aerial rescue:
* Arboricultural Association AA technical guide 1 Tree climbing and aerial rescue
State personal fall protection performance criteria to consider when tree climbing in accordance with AA guide TG1
Personal fall protection performance criteria include:
* the system comprises of a primary system and a backup
* should be attached to independent anchors where possible
* if there is no suitable independent anchor it should be installed over a shared anchor
State working considerations in relation to tree climbing
Working considerations in relation to tree climbing may include:
* the climbing ropes must be kept as taut as possible and any slack must not exceed 500mm
* rope or cord used for friction hitches must be of a suitable type
* no potential fall distance exceeds 500mm
* karabiners must have a spring-loaded, self-locking gate that requires at least three distinct movements to open it
State the basic legal and environmental factors and how they impact on the work
Legal and environmental considerations could include:
* landowners’ permission
* Tree preservation order
* nesting birds
* bat roosts
* presence of other valuable flora and fauna
* other
Potential impacts:
* stops work from taking place
* delays work from taking place
* restricts work
* other
Describe the potential environmental damage that could occur and how to respond appropriately
Potential environmental damage may include:
* damage to retained trees
* wildlife disturbance
* other
Appropriate responses may include:
* work sequence chosen to minimise subsequent damage to retained trees
* wildlife assessments completed prior to work
* other
Perform a tree condition assessment of the tree and work at height assessment prior to commencing the work
(VTA)
Potential hazards that may be encountered may include:
* evidence of cavities, decay or decay fungi
* deadwood and broken branches
* dead or flaking bark
* v shaped unions
* cracks
* nesting insects
* the presence of power lines or telephone wires
* targets and obstacles underneath the tree
* other
Discuss a working at
height assessment
like a risk assment but at heights what can be done to impove saftey?
Working at height assessment may include:
* can the work be carried out from ground level
* the use of a Mobile Elevating Work Platform (MEWP) to prevent a fall
* The use of suitable equipment minimises the distance and consequence of a fall
Explain how the species, condition of trees and time of year affect the work
Species, condition of tree and time of year may affect tree
climbing owing to:
* brittle timber characteristics leading to weaker anchor points
* dead, diseased, or dying trees may prevent tree
climbing taking place
* trees in leaf may reduce visibility and effective communication
* winter months may present problems such as windy conditions, wet or icy branches, extremities of cold
* summer months may present problems such as pollens, dusts, irritants
* other
Describe how to ensure that access equipment and systems are in safe working order
To ensure access, tree climbing equipment and systems are
safe to use operators must ensure:
* pre-use check of equipment system undertaken
* on-going equipment system checks during climbing
* ongoing maintenance
* other
Inspect all access/tree climbing equipment to ensure it is safe and fit for use under manufacturer’s instructions and relevant legislation
what equipment and how
Harness check
- How many carrabinas
- any wear
Rope check
- any wear
Carabiner
- Click check
- burring
Prussic
- Any wear
State why it is important to read and understand manufactures information
The importance of reading and understanding manufactures
information is:
* correct equipment application
* how to correctly configure equipment
* compatibility of equipment with other components
* maintenance requirements
* inspection
State different methods used to safely access a tree
Different methods that may be used to access a tree can include:
* moving rope technique
* stationary rope technique
* ladders
* spikes/climbing irons
* Mobile Elevating Work Platform (MEWP)
* other
State the difference between a personal fall protection anchor and a positioning anchor
The difference between a personal fall protection anchor
and a positioning anchor may be:
Personal fall protection anchor:
* An unquestionably reliable anchor point that supports the
full potential load of a climber and equipment
Positioning anchor:
* An anchor that is used to aid the climber with positioning
and prevent a pendulum swing
