Firefighters in Yate were faced with an unusual call-out last week - dealing with 100 litres of foam accidentally released on an industrial estate.
A group of the emergency service workers were called to attend the incident on March 31 after a protection system was activated.
Crews were sent to a unit in Yate and found "quite a sight".
They then worked to clear the area and isolate the supply, containing all the foam on site.
Posting on Twitter, Yate Fire Station said: "#yateoncall had a early morning call, on arrival we found a protection system had accidentally activated resulting in quite a sight!
"We helped isolate the system, all the foam was contained on site."
