Posted By Robert S Woods CIEH COSHH presentation says "Types of Hazardous Substances: Liquids, Solids, Dust...." Anyone got an example of a solid covered by the above and what would be the route of exposure?

Posted By J Knight Cytotoxic medication in tablet form would be a solid and subject to COSHH. I know most medicines aren't, but cytotoxics are, John

Posted By Diane Thomason Anything that comes in a crystalline or powder form is a solid. So anything that comes as solid to be made up into solution could be considered. The contents of, say a sachet of Weedol are solid until made up into solution. An example of a very hazardous solid is crystalline phenol. Normally thought of as a hazard when in solution, but if crystals come into contact with skin, there is enough moisture in the skin for burns and skin apsorption to occur. Another example is sodium hydroxide pellets. The routes to worry about would be skin and eye contact. Some detergents come as powders or pellets too. Some free-flowing solids like powders are dusty when poured so you'd consider inhalation of dust as well as skin/eye routes. Powders can also be ingested if the powder sticks to your face and lips. These are possibly not good examples for you as I'm thinking of a lab environment. If you want to email direct to discuss other examples please feel free.

Posted By steve e ashton Any and all dusts which can be inhaled... 'Solid' doesn't just mean a solid block - it includes sawdust and asbestos fibres and welding fume and etc etc.

Posted By Robert S Woods CIEH list: Powders Gases Liquids Solids Dust Bacteria and viruses I thought reactive or sensitising metals and pharmaceuticals would fit the bill. Thanks for your help. PS, the waste mentioned is rarely solid except in desert dwelling animals.
