Chapt. 6 Managing Risk Flashcards
Failure to act in a reasonable manner
breach of duty
In a legal sense, breach of duty resulting in damage or injury
causality
In arboriculture, a tree condition or characteristic, either naturally occurring or created, that negatively affects structural stability.
defects
Obligation or responsibility
duty
In tree risk assessment, the professional assessment of the “likelihood for a tree to fail within a defined period of time”
failure potential
Physical injury or property damage
harm
Situation, condition, or thing that may be dangerous. 1) in tree management, a tree or tree part that is likely to fail and cause damage or injury, and the likelihood exceeds an acceptable level of risk. 2) in tree care or forestry operations, the presence of a condition or a situation that may cause harm or injury to workers
hazards
In risk assessment, the period of time between scheduled visual examination of a tree, for example, one year
inspection interval
Something for which one is responsible. Legal responsibility.
liability
Method of risk control in which action is taken to reduce the likelihood of loss (damage or injury)
loss prevention
Minimize the impact of losses e.g. storm response plans or aerial rescue training
loss reduction
Failure to exercise due care
negligence
Likelihood or probability that something will happen. Usually associated with negatived consequences. In tree management, the likelihood that a tree or tree part will fail and cause injury or damage
risk
Process of evaluating what unexpected things could happen, how likely it is, and what the likely outcomes are. In tree management, the systematic process to determine the level of risk posed by a tree, tree part, or a group of trees
risk assessment
Risk control strategy in which an activity is avoided to eliminate the possibility of loss (injury or damage).
risk avoidance
Component of a risk management program in which proactive measures or strategies are used to reduce risk
risk control
Systematic application of management policies, procedures, and practices for identifying, evaluating, treating, monitoring, and communicating risk
risk management
Risk control strategy that moves part, if not all, of the responsibility for risk assessment and/or abatement to another party
risk transfer
Degree of care that a reasonable person should exercise in performance of duty of care
standard of care
1) person, object, or structure that could be harmed (damaged or injured) by a tree or tree part in the event of failure. 2) Location of target pruning
target
To do what a person of sound judgement and rational behavior would do; to adhere to the standard of care
to act reasonably
Methodology by which factors affecting the degree of risk are evaluated and assigned a rating
tree risk rating system
Process of taking action to lower risk of injury or damage
tree risk reduction
Risk control strategy in which one attempts to learn more about the risk in order to increase the ability to predict what will happen
uncertainty reduction
Applying treatments that mitigate hazards and reduce risk
risk abatement
