Good Morning All, We are having isocyantes introduced onto our site as part of the process for a new production line. The process will be contained and the extraction and ventilation is suitable and sufficient. I will need to store the material both outside and inside. This is a new one on me and I am aware that this is going to fall under DSEAR and ?COMAH regs. Any advice on this issue and how best to transport from outside to inside in a safe manner? I have received the MSDS for the material we are using so I can can a lot of informartion that, I don't have much experienceof this yet and want to make sure that I cover all aspects. I am in the process of filling out the Part B permit with the local council and will be conducting risk assessments.

Hi VCOLLIER It may help generate a better response if you could provide more details of the process (spraying, glueing etc?) and volumes you are using? I presume its in the tonnes if your considering COMAH? and also what type of iso (HDI, MDI etc) and its state (some iso are solid at room temp). We have just managed to get rid of isocyanates form our spray production (THANK GOD). When using iso we introduced: - Biologuical monitoring (urine sampling at £50 a pop - 6 weeks in, 12 weeks in then annually) - Air fed respirators MUST be worn if spraying - Air monitoing - in adjacent building too to ensure the fumes are not re-entering other buildings - Breathing air line testing every 3 months (for the air fed respirators) - Aswell as the usual booth clearance times, manometers etc We also looked and instant exposure indicators that changed colour when exposed to ISO , but these are not available for HDI Isocyanate. There is plenty of guidance for the use of isocyanate in the automotive spray industry from the HSE, but this may not be relevant depending on your process?? As far as transporting the substance, it will depend on your volumes used, distance travelled, state (liquid etc), static issues, ventilation, etc etc if I recall correctly only 50Ltr (presuming your Iso is a liquid state) should be stored inside , but im prepared to be corrected? Good luck and remeber the CoSHH hierarchy - AVOID - SUBSTITUTE etc
