SEVEN fire crews braved shattered glass and the threat of gas cylinders after a heating system exploded and set fire to a greenhouse.

The crews were called to reports of a fire at an agricultural site in Folly Chase, Hockley. 

Initial reports warned a number of gas cylinders may be in the area affected by fire, and therefore further fire crews were requested for support, the service said. 

Station manager Steve Osborn said: "The fire started after a heating system exploded and set alight to around 25 per cent of a greenhouse building.

"With a large quantity of shattered glass, fire and the possibility of gas cylinders, this was a difficult incident for our crews.

"But thanks to their hard work and skill, our firefighters quickly surrounded and extinguished the fire and therefore saved other buildings on site.

"Thankfully none of the gas cylinders were involved in the fire so we were able to bring the incident to a close by 8.40pm."
