It is a law that every manufacture MUST put out a MSDS or Material Safety Data Sheet for all products used. School's are expected to keep all these forms on file. The forms should always be somewhere where they have easy access. A great place to have the MSDS sheets would be on the wall in the photo lab. Material Safety Data Sheets for all chemical products, for all items, like film developer, and equipment, contain country specific regulatory information. If you were to get developer or any other chemical in your eye it would be a good idea to grab a sheet on the way out to the hospital.
