The state has come up with a set of guidelines for local communities and schools, on the best ways to deal with suspicious letters or packages. Three schools have received mail containing unknown white powder in recent days.
The Advisory Council of the Department of Emergency Services and Public Protection, Division of Emergency Management and Homeland Security said some communities have asked for guidance on how to deal with possibly suspicious mail, so the agency worked with public health, police and fire officials to come up with an updated protocol.
The guidelines include a description of the kinds of mail which the recipient should continue suspicious — including letters or packages containing an actual threat, or with oily stains, discoloration or odor.
Supervisors are reminded to keep everyone exposed to any substance in the same area while they wait for further instructions, and to turn off fans or air conditioners.
