CHIP list 16 headings whihc must appear on a safety data sheet. The information included under these headings will help you make sure that the product is used safely. For example, the safety data sheet should describe the hazards the chemical may present, provide information on how it should be handled, stored and disposed of and explain what should be done in the case of an accident. I.e. first aid.
Although these headings are obligatory, CHIP does not specify exactly what informaiton that should be included under them.
