Building blocks minimise fire risk in stacks

2000 sheehan lego block production

A court case concerning a major fire at a plastics recycling plant reconfirmed the fact that plastic stacks should have restricted dimensions and 6m fire breaks between each one.

Many companies are now turning to interconnecting blocks to segregate waste streams and meet legal requirements. Often referred to as ‘Lego blocks’, they are fire prevention certificated on Environment Agency-permitted sites, and quick and easy to construct (pictured).

Chris Sheehan, managing director of Oxford-based Sheehan Group, produces such interconnecting blocks. He said sales had increased by 200% in 2017 while 2018 is off to a good start with enquiries coming in daily.

He said: “The blocks are used for a variety of storage solutions and their flexibility makes them popular. But in the past year we have noticed a marked increase in the number of clients purchasing them specifically to use to store waste safely. Operationally the blocks enable people to construct waste and recycling storage areas quickly. They do not require planning permission, foundations, steel reinforcing or shuttering, so they represent excellent value for money.”

Interconnecting blocks are cast in accordance with BS EN 15258:2008 and are quick to install, with many contractors fitting more than 100sq m a day.

“In terms of hazardous waste, the vital benefit is they minimise the likelihood of a fire starting and, if one does, it reduces the risk of it spreading to neighbouring bays or sites.

“Before building bays, it is important to conduct a fire prevention plan to ensure they are constructed to the right specification to safely store the waste involved.”
