  • Section 4.2.3.3 of NFPA 704 guides how to handle multiple chemicals.

    You can combine the worst of each category into a composite, list each individually, or do a hybrid option.

    The posts saying there are two chemicals are true but likely incomplete… There are probably several different chemicals and they decided to go with the hybrid method.

    My guess is that they combined the worst rating of everything that doesn’t need special handling, and have a stand alone for the chemical that is incompatible with water (or even combined for several chemicals that are incompatible with water).




  • To also explain a part of the American tax system… people who are super excited to get a ton of money back on their taxes via refunds are complete idiots.

    That’s a direct function of paying too much withholding and not calibrating against their relevant deductions. Some of these people also feel that their tax burden has gone up if their refund is smaller from one year to the next, which may or may not be accurate.
