Reprocessing Explosion

Print Toner Cartridge Reprocessing Hazards – Over reliance on Generic Data

A UK, Sussex-based recycling company has been fined following an explosion and fire at one of their sites. Portsmouth Crown Court heard how a massive explosion occurred at the site on 3 October 2011 in Lingfield, Surrey, following the storage of print toner on site. Eight people were injured (five seriously) as a result of the explosion, when toner cartridges being shredded and reprocessed.

The investigation also found that the company who designed the reprocessing machinery that was used to shred and process the toner cartridges, did not consider the likely misuse of the machine by overloading the processing of toner with more than a residual amount of toner powder left inside; it was found they relied on generic data to determine whether an explosive atmosphere may arise.

Reliance on generic data can lead to catastrophic consequences. Sigma-HSE have ISO 17025 quality-controlled laboratories to provide accurate and relevant data to support your basis of safety. For further information email info@sigma-hse.com or call our Client Support Team on +44 (0)1962 840570
