Two Firefighters, Two Others Treated After OrganoPhosphorous Contamination Monday

A total of four people – two of them firefighters – were taken to local hospitals for treatment after exposure during an accidental spill of organo phosphorous in Concord Monday.

Details of the spill and exposure were not immediately available but a significant HazMat response descended on Bisso Lane in Concord after it was reported at 11:54am.

From Wikipedia:
Organophosphorus compounds (OPCs) are a diverse group of organic chemicals containing phosphorus, widely used as insecticides (e.g., malathion), nerve agents (e.g., sarin), and in therapeutic agents. They are highly toxic, operating by irreversibly inhibiting acetylcholinesterase, which causes severe neurological impairment, respiratory failure, and acute cholinergic toxicity, making them dangerous contaminants in the environment.

Con Fire officials said two people were taken to local hospitals with “moderate” exposure.

Incident commanders reported that the responsible chemical has been isolated with all necessary decontamination protocols undertaken. Fire and Hazmat crews were expected to remain on scene for an extended time.
