To placard, or not to placard, that is the question. While it’s a general truth that each person who offers for transportation or transports any hazardous material must comply with applicable placarding requirements, fortunately there are many instances when placarding a shipment of hazardous materials is not required by the U.S. Department of Transportation’s (DOT) hazardous material regulations (HMRs).
Although there are exceptions with which you may already be familiar, such as the “limited quantities” exception, there are other less well known exceptions, such as those based on the weight of a shipment of specific hazardous materials.
The information on placarding exceptions is very useful to our EHS staff. It will be a nice tool for communicating with the shops as well.
