Final answer:
When working on terrorist and criminal incidents, it is important to document observations and minimize contact with contaminated surfaces.
Step-by-step explanation:
When working on terrorist and criminal incidents, it is important to follow certain guidelines. One of these guidelines is to document your observations. This helps to provide accurate and detailed information for investigations. However, it is crucial to remember that taking pictures of the incident scene would not be appropriate, as it might compromise the integrity of the investigation. Another guideline is to contact contaminated surfaces only when absolutely necessary. This helps to minimize the risk of exposure to hazardous materials and ensures the safety of individuals involved in the incident response.
