WAKEFIELD – Provisional Fire Chief Thomas M. Purcell reports that the Wakefield Fire Department responded to a chemical reaction that required HazMat attention.
On Sunday, Aug. 4, at about 4:45 p.m., the Wakefield Fire Department responded to reports of a vehicle fire in the area of 23 Cedar St.
When firefighters arrived on scene, they observed smoke emanating from an F-550 Utility truck. Firefighters also heard sudden bursts and popping noises and smelled a strong chemical odor.
Firefighters learned that the truck contained a 5-gallon plastic bucket of powdered chlorine, which was cracked. The chlorine was compromised by the rainfall, which created several small chemical reactions. These reactions dissipated quickly.
Combustible gas meters and thermal imaging cameras deployed by companies on scene all came back with negative readings. A tier 1 HazMat response was requested, and the state Hazardous Materials Emergency Response Unit arrived shortly thereafter.
The state HazMat unit quickly conducted a hazard and risk assessment of the situation. They confirmed the cause of the reactions and continuously metered for hazardous conditions.
HazMat technicians deemed there were no concerns or threats to nearby occupied homes aside from a slight odor. Firefighters notified homeowners in the immediate area to close their windows and shut down HVAC systems temporarily.
The state Department of Environmental Protection (DEP) was notified and responded. The DEP, HazMat technicians, and Wakefield Fire were able to contain the remaining product and wash it away safely.
The Town’s Department of Public Works provided dichlorination mats for a nearby catch basin, which neutralized any runoff.
All companies were clear of the scene by 10:45 p.m.
It was later determined the truck carrying the chlorine belonged to a vendor who was contracted to provide the product for the Town’s ongoing water main replacements.
The Fire Department reports that the area is completely safe for outside air activities including operation of HVAC systems.
