Chloropicrin is a warning agent introduced into the structure prior to fumigation with Vikane specialty gas fumigant. In order to avoid direct exposure to the fumigant being released, chloropicrin must be released within the structure at least 5 to 10 minutes prior to introduction of the fumigant.

Place a handful of wicking agent (e.g., cotton) in a shallow chloropicrin evaporation container. Do not use containers or application equipment made of magnesium, aluminum, or their alloys, as chloropicrin may be severely corrosive to such metals. To enhance the distribution of chloropicrin throughout the structure, place the shallow chloropicrin evaporation container in the air stream of a fan. Pour chloropicrin over the wicking agent. When adding chloropicrin to evaporation containers, dispense no more than 3 fl oz per container. Use 1 fl oz per 10,000 to 15,000 cu ft (30 mL per 283 to 425 cubic meters) of space to be fumigated or follow dosage rate calculated by the electronic Fumiguide system. Use at least one chloropicrin introduction site for each 45,000 cu ft of space to be fumigated. When applying chloropicrin at multiple chloropicrin introduction points within a structure, start at the point farthest from the exit and work toward the exit. Removal of all chloropicrin evaporation containers from the fumigated space during initial phase of aeration after tarp removal will aid in the dissipation of the warning agent from the structure.
