Lafarge Cauldon cement plant is one of the largest cement manufacturing sites in the UK producing 1.3 Million Tonnes of cement every year. The workforce can come into contact with dust that settles on the overalls, requiring the overalls to be cleaned more frequently. Currently Lafarge do not have any means of cleaning onsite apart from using compressed air. Compressed air is readily available but can cause air to enter the bloodstream, this can be fatal. During one of their monthly safety meetings, Lafarge identified a need for an alternative and safe practice.
