MSDS on any suspected Class D hazards
This list is by no means “all encompassing”. In many cases, one reference may lead you to others that are not listed here, but this is a good start for gathering data to help your customers with this unique protection problem. It should be noted that Class D hazards require a true partnership between you and your customer. They know what they use, how they use it and when they have fire difficulties. Remember that unless your customers make the combustible material themselves that by law their supplier must supply them with MSDS. Don’t be shy about asking for this important informative safety document as you investigate your own sources. No one should know the specifics of a given material and have more experience than the manufacturer.
