What type of evidence should be collected first at an incident scene?
Answer: Perishable or transient evidence that may change or disappear

What is a fault tree analysis used for in incident investigation?
Answer: Working backward from an undesired event to identify all possible combinations of failures and conditions that could cause it
Fault tree analysis is a deductive technique that works backward from an undesired event to identify all possible failure combinations.
Why should witness interviews be conducted separately during an incident investigation?
Answer: To prevent witnesses from influencing each other's recollections and to get independent accounts
