I have received a Material Safety Data Sheet for building panels that are made almost entirely from cement and fine aggregate. Look at some of the stupid errors it contains:

It lists "cement" as an ingredient, but does not indicate type nor its CAS number.
It does not mention ingredients that I know, from visual inspection, are included -- such as the fine aggregate.
It provides fire fighting instructions and advises against ignition sources -- for a non-combustible product.
It does not differentiate between exposure to dust from cutting and exposure to the intact concrete.
It advises against inhalation, but is silent about containing crystalline silica, a health hazard present in all concrete products.
It has asinine disposal requirements, for concrete, such as: "Disolve or mix the material with a combustible solvent and burn in a chemical incinerator equipped with and (sic) afterburner and scrubber." And,
We are advised to store the concrete panels in "a tightly enclosed container."

But that errors in the MSDS report are not the funny part. The joke is that:

The manufacturer published the document!

Please - if you are responsible for your company's product literature, use common sense when you read the document. And if you do not feel qualified to review a document, ask the lab to explain their report or find a qualified consultant to help you.
