Have you ever wondered what that Color Coded Diamond that's on a lot of the MSDS sheets or on the backs of HazMat trucks and the numbers meant? Attached is a rating guide and the meanings of those colors and numbers.

I use a couple of others.

This one includes a few more of the Specific Hazard designations. The descriptions are a bit different as they are based on the HMIS. The NFPA and HMIS systems are similar, but different:nfpaexample.jpg
This one provides guidance on the HMIS PPE classes:HMIS%20Poster%20English.jpg
Hazmat also uses the diamond, but is somewhat different:hazmat-s1-2.jpg
At least, that's the best I can figure.

Good stuff there, Dave. I hadn't seen the chart when I did a search so I thought posting it would help. Thanks for those extras. I wasn't aware there were other charts like that. Although, as a kid, the best kinds I remembered that will always stick with me were simple ones like the following. They said it all...

The placards are also used in Canada and I believe in the U.S. as well when transporting dangerous goods. One of the main reasons you have to display the placards on your vehicle is for first respondents, they can quickly identify what if any possible immediate dangers are present in the case of an accident or perhaps a fire that is close to a parked vehicle. A lot of people don't know this but it's actually against the law not to display the placards, there are however a few under 100 kg exceptions here in Canada.
 
As of November 2013, there is an agreement between many nations for an alternate system.
Not sure what the details are but it's coming.
 
It is called Globally Harmonized System GHS.

GHS stands for the Globally Harmonized System of Classification and Labeling of Chemicals. GHS was developed by the United Nations as a way to bring into agreement the chemical regulations and standards of different countries. In short, it is an international attempt to get all countries on the same page.

GHS is primarily concerned with the classification of chemicals and the communication of hazards related to those chemicals to users of the products downstream via warning labels and safety data sheets. Link to informational paper (white paper).

The OSHA Hazard Communication Standard (HazCom) remains the law in the U.S. and has been revised to include alignment with GHS system.

This system uses pictograms instead of the colored diamond.
 
Here's the one I remember most. I don't know if they are still around but it might be good to have if there is any chance of kids (or anyone) getting around your chemicals. Pretty easy to understand.

The moderators would like to thank all of the members that contributed to the original thread upon which this thread was based, as well as those that asked questions showing what was missing. Because of the extra length and interest in this thread we have created the above consolidated version making for an easier read. We encourage all members to read, comment, and ask questions in the original thread, NFPA Diamond Guide.

The Library threads should not be considered to constitute a complete education. Instead, they're more like reading a single book on the subject of recovery and refining. There is so much more information on the forum, and it is impossible to include it all in these condensed threads. Members are strongly encouraged to read the rest of the forum to round out their education.

For those who prefer a printed copy, a pdf file of this thread is provided below.
