Is there any relationship between the NFPA or HMIS rating and the potent compound safety rating?

The National Fire Protection Association (NFPA) rating (0-4) was originally designed for firefighters that were responding to structure fires (under fire conditions) and needed to be aware of hazardous materials within the building, such as hydrogen or chlorine.

The Hazardous Materials Information System (HMIS) rating is an adaptation of the NFPA rating and is intended for laboratory environments.

Both have little to no applicability to potent compound safety or potent compound categorization.

In addition, most authors of safety data sheets (SDSs) do a poor job of assigning the proper NFPA or HMIS ratings. Even if the author of a safety data sheet assigned all zeros (0) to the NFPA or HMIS rating it does not mean the rating was correctly performed or that the material is non-hazardous.
