GHS vs NFPA…HMIS and WHAT THAT MEANS TO YOU.
What exactly are the differences between GHS, NFPA and HMIS?
Actually there are several differences between these marking systems.
And while OSHA is not demanding that companies stop using NFPA and HMIS
in the workplace, when it comes to labeling it appears that neither the NFPA or the HMIS system are
a substitute for GHS labels. First
of all the GHS numbering system is very different from both the NFPA and HMIS
numbering systems. And while with the
previous version of the HCS, OSHA
allowed for meeting the intention of the rule, that is no longer the case. OSHA very clearly states that the format for
all hazardous chemical signs and labels on transporting containers as well as
in the workplace must be labeled with the same information that appears on GHS Labels. They site many very compelling reasons for
this, among them; although many containers were previously
labeled with a numbering system (NFPA or HMIS) they often were not titled with
a chemical name nor enough other vital information to assist employees in
handling the hazardous chemicals in a safe manner.
I must digress here
for just a moment…. The SAFETYCAL
Hazardous Material Labeling System has ALWAYS contained not only the numbering
system but also the chemical Name, necessary PPE, Target Organs and needed
emergency first aid information…it seems, once again, SAFETYCAL was thinking
forward and ahead of our time….
Back to topic...Most people that have read the GHS standard
agree that the difficulty arising in trying to compile the systems comes down
to the numbering system. While both NFPA
and HMIS rate hazards in an ascending order (0 being safe and 4 being the
highest hazard) the numbering system for GHS more closely matches the hazard order of
DOT. They make a further point that
although both NFPA and HMIS have been helpful systems to address HCS, the fact
is neither system originated from a
governing entity and therefore, OSHA hopes that in the near future these
systems will too, embrace the GHS system.
Although we are all concerned about confusing the very
employees we are attempting to protect, OSHA clearly states that with proper
training, employee knowledge will be brought into line with the GHS. The benefits of clear and consistent
information far outweigh any other argument.
All that said, GHS is here to stay. It is likely that in the near future both NFPA and HMIS
will find a way to come in line with GHS. Until then,
it is important to check with your local fire department. They will may require that you continue using
the NFPA numbering system and diamond on all hazardous chemicals or at the very least on the outside of your buildings.
