Posted By Tracey Arnold You are on the right track, you should have MAterial Safety data sheets for all the substances that are used in the workshop that have hazard labels. If you do have access to these they will give you an idea of what they can and can't be stored with, if you don't then it would be advisable to obtain them as you should have them available for reference at all times (in the workshop). They are also useful for carrying out your coshh assessments. Corrosive substances are always best to be stored on a bottom shelf and make sure that any oxidisers are also on the bottom. I would recommend that you store all your hazardous substances in metal cabinets that are 'bunded' (ie; have a reasonable sized catchment tray to catch any spillages.) Flammable substances should be stored in metal fire proof cabinets and there is a limit as to how much flammable substances you can store in a workshop at any one time. Aerosols should be kept separate also. Your best bet for guidance would be COSHH (COntrol of Substances Hazardous to Health) there is a website called www.coshh-essentials.org.uk and this might be of some help.
