Where a chemical name is confidential it may be left off the label or safety data sheet and replaced by its generic name, but only if the chemical is classified as harmful or irritant or falls below the relevant cut-off, and the actual name must be disclosed when a medical practitioner, or a person using or handling the chemical, asks in writing, for use only in protecting worker safety and health. Where the exact amount of an ingredient cannot be given, proportion ranges (very high above 60 percent, high 30 to 60, medium 10 to 30, low under 10) are stated so that the hazards of the formulation remain as clear as possible.
