Placarding Hazmat Vessel Shipments
Identifying dangerous goods and communicating their hazards to port and vessel personnel is vital to worker safety and the on-time delivery of the cargo. In every even-numbered year, the International Maritime Organization (IMO) publishes a new edition of its International Maritime Dangerous Goods Code (IMDG Code). This manual lays out the international standards US hazmat shippers must follow in addition to DOT regulations to send shipments by vessel.

Communicating Hazards for Vessel Transport
Placards are used to indicate that a Cargo Transport Unit (CTU) contains dangerous goods and what kind. Dangerous goods vessel shippers must placard CTUs in accordance with the specifications at IMDG Code 18.104.22.168. Placards must:
- Be a minimum of 250 mm on each side, and
- Match the same specifications for symbol and color as required for labels in IMDG 22.214.171.124, and
- Display the hazard class or division in numbers at least 25 mm high.
In addition, to ensure continued communication in the event of an incident at sea, placards must be durable enough to survive three months' immersion in the sea. [IMDG 126.96.36.199.1.2]
Unless specifically excluded, CTUs containing any amount of dangerous goods must be placarded for the dangerous goods they contain. In most cases, the placards must be displayed on all four sides of the CTU. [IMDG 188.8.131.52.4] The IMDG Code does not specify exactly where on each side the placards must be placed, but it does require that placards be clearly visible and stand out from their background, or that they have a solid or dotted outside border. [IMDG 184.108.40.206.2]
Placards must be displayed once the dangerous goods are offered for transport and removed once the dangerous goods have been unloaded. Placards for both the primary and the subsidiary hazards of all materials in the CTU must be displayed on the outside of the CTU. [IMDG 220.127.116.11.3] (Special rules for placarding CTUs containing radioactive materials can be found at IMDG 18.104.22.168.5.)
When Are Placards Not Required?
Placards are not required on CTUs if the markings and labels are clearly visible from the outside or if the CTUs only contain limited quantity or excepted quantity packages. [IMDG 22.214.171.124 and 126.96.36.199] Placards are also not required on CTUs that contain any Division 1.4, Compatibility Group S explosive materials. If CTUs contain substances and articles in more than one division of Class 1, the CTUs only need to display the placards representing the highest risk. [IMDG 188.8.131.52.2] A DOT Extra
The US Hazardous Material Regulations require additional placarding and other communications for toxic inhalation hazard materials in Divisions 2.3 or 6.1, even if the shipment is otherwise prepared under the IMDG Code. [49 CFR 171.23]
Placarding requirements are an essential part of shipping dangerous goods by vessel. The latest edition of the IMDG Code, the 2014 edition, includes many changes to the vessel shipping rules. As with each new IMDG Code edition, compliance is voluntary in the year following publication (2015) and mandatory in the next even-numbered year (2016).

I was able to present my scenario to the instructor and worked thru the regulations together. In the past, I attended another training firm's classes. Now, I have no intention of leaving Lion!
Senior Environmental Engineer
I will never go anywhere, but to Lion Technology.
I used the IT support number available and my issue was resolved within a few minutes. I don't see anything that could have made it better.
I like the consistency of Lion workshops. The materials are well put together and instructors are top notch!

Our instructor was very dynamic and kept everyone's interest. Hazmat shipping can be a dry, complicated topic but I was engaged the entire time.

This was the 1st instructor that has made the topic actually enjoyable and easy to follow and understand. Far better than the "other" training providers our company has attended!

I have attended other training providers, but Lion is best. Lion is king of the hazmat jungle!!!

The instructor does a great job at presenting material in an approachable way. I have been able to save my company about $30,000 in the last year with what I have learned from Lion!
I attended training from another provider and learned absolutely nothing. Lion is much better. Hands down.
The instructor's energy, enthusiasm, and knowledge of the subject make the class a great learning experience!
