The hazard pictogram that appears on the supplier label and SDS is very important. It provides you with information about the primary hazard posed by a product. It also indicates whether the product is dangerous to touch or breathe, is easily combustible, unstable or reacts negatively (when mixed) with other materials. Look for a pictogram that is framed by a red square set on a point. The exception is the biohazard pictogram which is in a round black border.
