Common questions
Why are unlined cans preferred over lined ones for fire debris?+
Can linings can contain organic coatings or adhesives that off-gas volatile compounds over time, contaminating the headspace and producing false accelerant signals during charcoal-strip extraction.
Can plastic evidence bags be substituted for metal cans in fire-debris collection?+
Nylon or other vapor-tight polymer bags are an accepted alternative for many samples, but metal cans remain preferred where puncture risk, heat, or long-term storage is a concern, since some plastics are permeable to volatiles.
