Manufacturer's Label
Suppliers of hazardous products must affix a label that meets the requirements of the Hazardous Products Regulations. If the hazardous product is still used in the container bearing the supplier's label, no additional label is required.

Workplace etiquette is required if:
– a dangerous product is generated (manufactured) in a workplace and used at that workplace,
– un produit dangereux est décanté (p. ex. transféré ou versé) dans un autre contenant, ou
– a supplier label is indecipherable (illegible) or missing.
