signal words, hazard statements and precautionary measures at the level of detail by the national authority represents the greatest training challenge. Training will be a key component of the overall GHS approach and should incorporate information as it is introduced into the workplace. Employees and emergency responders will need to be trained on all new program elements, from hazard statements to pictograms. Bear in mind, if the importation of products using only GHS labeling is permitted prior to its adoption in the United States and Canada, employers may need to begin employee training earlier than expected.
