The Material Safety Data Sheet, sometimes called OSHA Form 20, must be prepared and furnished by every
manufacturer of a product used today in the USA. By law, you are entitled to see a copy of this MSDS for
every product you work with or are exposed to in your working area.
This sheet has several portions which describe the product, its hazardous components (if any), boiling
point, flammability, reactivity, how to handle, how to dispose, how to store, conditions to avoid,
protective clothing and many other important characteristics pertaining to the safe use of the product.
Note especially Section 2 where all hazardous materials must be shown, along with their TLV numbers.
