What do you use to disinfect your tools before the next dig out?

[fire49]

1 dawn

2 disposable tools

3 just throw the tools away and get a new one, so there is no question


Also document your method maybe sop

Our county investigation team uses "Formula 409" and paper towels to clean our tools when we are finished with each sample. This is what the State Fire Marshal suggested and what they use. Just spray on and wipe it off... no water needed. They stated the chemicals in the 409 didn't affect any of the samples at all.

I use a small pump up sprayer with water and dawn mixed in it.

I think I would send a clean sample of the 409 you use to the lab to see what they see::::

Well, since it was the State Fire Marshal that told our team to use it, I figure they have already tested it. I'm not sure if it's detectable or not... I'm just doing what I'm told.

I would feel more comfortable with documentation, then going to court one day with none

It is necessary to cleanse each tool used for excavation or evidence sampling before taking it into the fire scene and, again, between evidence collection sites within the scene. Concentrated liquid dishwashing detergents effective at dissolving grease, including Ultra Dawn Concentrated Dishwashing Detergent, have also been found effective in dissolving ignitable liquid residue on steel tools when scrubbed with a clean scrub brush and flushed with clean water. Be sure to submit a sample of the liquid detergent to your forensic laboratory to ascertain its properties and ingredients.

If investigators have an accelerant detection canine or sensitive hydrocarbon detector available consider using it to double-check the tools after cleaning and prior to use.

Note that ignitable liquids derived from crude oil are generally not soluble in water alone.

I use Ivory soap on my tool.
