Question

Describe the handling and preservation of fire debris evidence:

A) Use airtight containers to prevent evaporation of volatile substances, label and seal properly, store in a cool environment
B) Expose the evidence to air to speed up the drying process, store in direct sunlight to kill any remaining bacteria
C) Rinse the evidence with water to remove contaminants, package in a paper bag for ventilation
D) None of the above

Answer 1

A) Use airtight containers to prevent evaporation of volatile substances, label and seal properly, store in a cool environment

Step-by-step explanation:

The correct answer is A) Use airtight containers to prevent evaporation of volatile substances, label and seal properly, store in a cool environment.

When handling and preserving fire debris evidence, it is important to prevent the evaporation of volatile substances. This can be achieved by using airtight containers. Proper labeling and sealing of the containers is also crucial to maintain the integrity of the evidence. Storing the containers in a cool environment helps to preserve the evidence and prevent degradation.

In contrast, options B and C are not recommended for handling and preserving fire debris evidence. Exposing the evidence to air can lead to further degradation, and storing in direct sunlight or rinsing with water can introduce contaminants and compromise the integrity of the evidence. Therefore, the correct handling and preservation method is described in option A.
