A new waste containment and collection system, designed to minimise the release of airborne contaminants during the waste collection process in the production of vaccines has met the approval of biological experts from the Health and Safety Executive.
Liquid waste is pumped to a double outlet inside a laminar air flow booth, each outlet is connected through a series of safety interlocks to an empty IBC which is placed on a weigh scale and connected by an airtight seal. A preset volume of waste is pumped into the IBC with the weigh scales acting as a safety back up, switching off the flow and ensuring overfill is prevented. Safety sensors prevent the flow of waste without the presence and connection of an unfilled IBC. Air displaced from the IBC is drawn off by an extraction system and passed through a HEPA filter to prevent airborne contamination.
Spray balls wash the chute and outlet valve with water to ensure that no waste product contaminates the top of the IBC on seal removal. The operator is then able to break the seal on the outlet of the IBC in order to fit the sealing cap. A localised extraction system removes the air within the area of operation, providing a further safeguard for operators against contamination by any airborne substances.
