Moorings2015 Posted December 12, 2019 Report Share Posted December 12, 2019 Hi, Just wanted a second opinion. Scenario. Acetone is applied to a rag via a dispenser and used to clean utensils. The rags are then disposed of into a metal waste bin which has a fusible link which closes the bin lid in the event of fire. Bins are emptied at the end of every shift, however lids are left open during operational hours. My thoughts are that a waste bin with a sealed lid would be a better solution - e.g. foot pedal to open the lid which automatically closes. Current practise doesn't control flammable vapour from entering the atmosphere where there are light fittings, 240v sockets etc. Justification for the fusible link waste bins were that when the bins are sealed, operators in the area feel the build up of fumes was uncomfortable when lids were opened. Any thoughts? Thanks. Quote Link to comment Share on other sites More sharing options...
Tom Sutton Posted December 13, 2019 Report Share Posted December 13, 2019 Acetone fumes are heavier than air so ignition sources low down would be a risk and stored in a well ventilated/sealed container.

Moorings2015 Posted December 16, 2019 Author Report Share Posted December 16, 2019 Hi Tom, thanks for the reply, I'm potentially looking at a occupational hygienist to carry out sampling as from looking at the MSDS there is also a health concern regarding current practises. Sampling should tell us whether its safe to have bin lids open or if when they are closed the concentration of vapour brings the area within the explosive range. My gut instinct tells me that by having bin lids shut it reduces both fire/explosion and health impacts. thanks. Quote Link to comment Share on other sites More sharing options...
Tom Sutton Posted December 17, 2019 Report Share Posted December 17, 2019 I think having the cleaning tanks and disposal bin located on the open workplace is a problem they should be located in a separate room with mechanical ventilation.
