LOUDON, N.H.- Several cars were involved in an accident in Loudon Wednesday after a fire suppression system at a gas station was accidentally activated.

Authorities say the gas canopy extinguisher system was accidentally activated by a service technician which caused a large cloud to be deployed and carried onto Route 106 impacting the vision of drivers.

1 person was transported to a local hospital for precautionary measures.

People filling up at the pumps were also covered in the powder.
