The Lead Detective™ contains less than one gram of Sodium Sulfide. Sodium Sulfide is a slight poison and mild irritant. The amount of the compound is well under the lethal dose for people in the event of consumption. There are no incidents of poisoning on file at the poison control centers we contacted for this chemical other than bulk industrial exposure. Lead sulfide formed in the test is poisonous, as is the leaded paint chip supplied. Warnings regarding these dangers are located on the box label, in the manual, on the bottle label, and on the label containing the leaded paint chip. We recommend storage under 100deg F, and no exposure to acid. Shelf life of the product is generally over 1 year. Once the solution is made up by the consumer, it has a 4-6 week useful lifetime.
