Chemical leak - Downing Street - Cambridge

A crew from Cambridge was called to a chemical leak at the Earth Science laboratories in Downing Street after a leak from a cyclinder of Sulfur Dioxide.

Firefighters cordoned off the area and entered the building wearing breathing apparatus following reports of a pungent smell in the building.

A small number of staff had already evacuated the building before firefighters arrived, but they assisted one woman out of the building who had inhaled the fumes and gave her oxygen.

Crews used gas monitors to measure the level of gas in the atmosphere before isolating the cylinder and used positive pressure ventilation fans to ventilate the building.

They then returned to their station by 5.24pm.

Station Commander Simon Thompson, from Cambridgeshire Fire and Rescue Service, praised the work of everyone on site. “The fire crew and on-site staff were absolutely exceptional from start to finish.”
