For hazardous chemicals, the manufacturer or importer gives the employer chemical safety data sheets setting out in detail the essentials: what the chemical is, who supplies it, how it is classified, its hazards, the safety precautions and the emergency procedures, and the employer forwards a copy of each product's data sheet to the Commissioner. The employer makes sure that hazardous chemical packages arriving at the workplace carry labels and come with the appropriate data sheet, keeps a list or register of the data sheets at the workplace, and gives the workers concerned copies of the sheets and the register and lets their representatives consult them whenever they wish.
