In light of a number of serious work accidents related to attaching an air hose to the top of a pressurised discharge container, Francis Ward reacted to chemical industry concerns and developed the patented 'Safety Air Feed'. Now the air hose can be coupled to the container at chest height, preventing the need to work on top of the container. The patented 'Safety Air Feed' improves the health and safety regulations for working at heights, but also speeds up the process of delivering chemicals. The patented 'Safety Air Feed' has also been designed so that it can be retrofitted to existing IBC's in service.
