Hi I am risk asssessing a small coffee roasting operation.

Various research has show diacetyl (buttery aroma) and pentanedione is released during roasting and linked to lung disease with TWA set in the USA.   I can't find them in EH40.

Diacetyl has now also been banned in in vaping fluids.

Does anyone have any experience with this in coffee roasting and what did you do?

Not every substance will have an EH40 exposure limit - different countries adopt their own controls dependent upon prevalent industry and research. The HSE is currently in consultation on adopting new IOELV's to EH40 as a consequence of 2017/164/EU

One source to identify global WEL is the GESTIS database

http://www.dguv.de/ifa/gestis/gestis-internationale-grenzwerte-fuer-chemische-substanzen-limit-values-for-chemical-agents/index-2.jsp

Diacetyl (Butanedione) has European Union, Germany and Switzerland WEL listed LTEL 0.02ppm / 0.07 mg/m3 STEL varying levels (EU 0.1ppm / 0.36 mg/m3) - the EU limit assigned under 2017/164/EU

An EU WEL is the Community Work Place Exposure limit referenced in REACH.

Pentanedione shows limits for Canada, Denmark, Germany and Switzerland.

You will need to determine the level of Diacetyl being emitted during roasting and if above EU levels establish engineering controls.
