SCOPE
AND
PURPOSE
This
document
compares
current
OPP
classification
and
labeling
requirements,
as
presented
in
the
OPP
Label
Review
Manual
and
regulations
(
40
CFR
156),
with
the
provisions
of
the
Globally
Harmonized
System
of
Classification
and
Labelling
of
Chemicals
(
GHS)
as
adopted
by
the
United
Nations
Economic
and
Social
Council
in
July
2003
(
text
at
http://
www.
unece.
org/
trans/
danger/
publi/
ghs/
officialtext.
html).
It
indicates
how
OPP
label
policies
would
need
to
change
to
be
consistent
with
the
GHS.

The
GHS
includes
classification
criteria
and
label
elements
for
some
physical
hazards,
respiratory
sensitization
and
chronic
effects
that
OPP
does
not
now
routinely
label.
Since
implementation
of
the
GHS
does
not
mandate
hazard
labeling
of
these
effects
and
there
are
no
standard
OPP
practices
to
compare
to
GHS
criteria
and
label
elements,
they
are
not
included
in
this
comparison.

OPP
requires
labeling
for
environmental
effects
not
covered
by
the
GHS,
which
includes
only
aquatic
effects.
These,
too,
are
not
included
in
this
document
since
there
are
no
GHS
provisions
to
compare
to
OPP
requirements.
OPP's
current
practices
would
not
need
to
change
to
be
consistent
with
the
GHS,
since
the
GHS
notes
that
authorities
may
impose
labeling
requirements
to
provide
supplemental
information,
including
information
on
hazards
not
covered
by
the
system,
provided
they
do
not
undermine
or
detract
from
GHS
label
information.
(
GHS
1.4.10.5.4.2)

It
is
important
to
note
that
the
GHS
is
aimed
at
harmonizing
classification/
hazard
identification
for
hazard
communication
purposes,
not
risk
assessment,
management
or
mitigation
measures.
(
GHS
1.1.2.6)
A
separate
exercise
is
required
to
determine
if
risk
management
measures
that
are
now
tied
to
hazard
classification
should
be
"
decoupled."
Initial
analyses
during
development
of
the
GHS
indicated
that
there
were
few
OPP
requirements,
beyond
labeling,
that
were
triggered
automatically
by
hazard
classification.
Consistency
with
the
GHS
does
not
require
continued
linkage
of
classification
with
measures
beyond
hazard
communication
in
labeling
and
safety
data
sheets.

II.
GENERAL
COMPARISON
OF
OPP
PRACTICE
AND
THE
GHS
(
THESE
POINTS
APPLY
ACROSS
HAZARD
CLASSES)

1.
GHS
organizes
the
hazard
characteristics
of
chemicals
based
on
"
hazard
classes"
(
specific
physical,
health
or
environmental
effects,
such
as
flammability,
acute
toxicity,
aquatic
toxicity)
which
are
sub­
divided
into
numerical
"
hazard
categories"
based
on
the
severity
of
the
hazard.
The
use
of
the
term
"
category"
is
thus
essentially
the
same
as
current
OPP
practice.
The
GHS
uses
Arabic
numerals
consistently,
while
OPP
uses
Roman
numerals.

2.
OPP
only
uses
one
symbol,
the
skull
and
crossbones
for
severe
acute
toxicity
and
products
containing
methanol
at
concentrations
above
4%.
The
GHS
uses
symbols
for
all
hazard
classes
(
but
not
all
categories).

3.
GHS
pictograms
are
composed
of
the
appropriate
symbol
surrounded
by
a
red
diamond­
shaped
border,
except
that
authorities
may
allow
a
black
diamond
border
if
the
chemical
is
for
domestic
use
only.
OPP
does
not
prescribe
borders
around
the
symbol.

4.
OPP
uses
three
signal
words
(
danger,
warning,
and
caution);
the
GHS
only
two
(
danger
and
warning).
OPP
prohibits
the
use
of
signal
words
for
environmental
or
physical
hazards;
the
GHS
mandates
their
use
for
some
categories
(
e.
g.,
extremely
flammable
liquids).

5.
GHS
"
hazard
statements"
are
simple
statements
of
hazard,
a
subset
of
what
OPP
calls
"
precautionary
statements."
GHS
does
not
specify
any
precautionary
statements
(
e.
g.,
first
aid,
personal
protective
equipment)
beyond
hazard
statements.
There
are
plans
for
future
work
to
harmonize
additional
precautionary
language
at
the
international
level
through
the
GHS.

6.
The
GHS
calls
for
product
identifiers
on
labels
but
does
not
specify
them.
It
also
calls
for
disclosure
of
ingredients
that
contribute
to
the
hazard
classification
of
a
mixture,
but
provides
that
national
rules
governing
disclosure
of
Confidential
Business
Informaton
will
take
precedence
over
ingredient
disclosure
provisions
(
GHS
1.4.10.5.2(
d).

7.
The
GHS
contains
conservative
bridging
principles
for
classifying
untested
chemical
mixtures
that
are
consistent
with
principles
currently
used
by
OPP.
(
For
example,
for
acute
toxicity,
see
GHS
section
3.1.3.5).

8.
The
GHS
also
contains
formulae
for
estimating
the
toxicity
of
untested
mixtures
based
on
the
toxicities
of
known
ingredients.
It
is
not
expected
that
OPP
will
use
this
approach.
Rather,
OPP
is
expected
to
require
test
data,
consistent
with
current
practice,
unless
there
DRAFT
7/
7/
04
4
is
a
sound
scientific
basis
for
changing
current
practice.
The
rules
for
classifying
untested
mixtures
under
the
GHS
are
designed
to
ensure
that
the
best
available
scientific
information
is
used
for
classification
of
all
types
of
chemicals.

9.
The
GHS
is
testing,
and
test­
method,
neutral
for
health
and
environmental
hazards
and
is
designed
to
permit
self­
classification
to
the
maximum
extent
possible.
U.
S.
law
recognizes
that
pesticides,
which
are
intended
to
be
biologically
active
and
have
effects
on
living
organisms,
should
be
subject
to
testing
and
approved
by
a
regulatory
agency
before
they
may
be
legally
marketed.
This
is
not
the
case
for
some
other
types
of
chemicals.
Some
regulatory
agencies
do
not
have
the
authority
to
require
test
data.
Chemicals
may
be
legally
marketed
without
prior
regulatory
approval
or
label
review,
and
it
is
up
to
producers
to
classify
and
label
them
based
on
the
requirements
of
the
appropriate
regulatory
agencies.
The
GHS
is
designed
to
meet
the
needs
of
both
types
of
systems.

10.
The
GHS
specifies
test
methods
for
physical
hazards.
To
be
consistent
with
the
GHS,
OPP
would
need
to
adopt
both
these
methods
and
the
corresponding
GHS
label
elements.

11.
Except
as
detailed
in
the
specific
hazard
class
comparisons
in
the
following
sections
of
this
paper,
other
existing
OPP
label
information
requirements
appear
consistent
with
the
GHS'
allowance
for
"
supplemental
information,"
so
long
as
that
label
information
does
not
undermine
GHS
label
elements.
(
See
GHS
sections
1.4.6.3
and
1.4.10.5.4.2
.)
For
example,
such
information
may
cover
hazards
not
covered
by
GHS
or
provide
greater
detail.

12.
Both
the
GHS
and
OPP
specify
that
labels
should
include
product
and
supplier
identifiers.
These
elements
of
the
GHS
are
not
"
standardized,"
but
are
generally
consistent
with
OPP
practice.

13.
Since
the
principal
purpose
of
this
document
is
to
indicate
label
changes
that
would
be
necessary
to
conform
to
the
GHS,
classification
criteria
are
presented
in
summary
fashion,
as
they
are
in
the
Label
Review
Manual.
This
document
does
not
attempt
to
include
all
exceptions
or
special
circumstances
that
might
lead
to
divergent
classifications,
which
of
course
could
lead
to
different
label
requirements
and
would
still
be
considered
consistent
with
GHS
implementation.

Summary
Comparison:

$
The
GHS
has
five
categories
for
acute
toxicity.
OPP
currently
uses
four
categories.
OPP
Category
IV
has
no
upper
limit.
GHS
Category

of

­
5000

COMPARISON:

SKIN
CORROSION/
IRRITATION
Summary
Comparison:

$
Both
OPP
and
GHS
have
a
single
category
for
skin
corrosion.
The
GHS
subdivides
this
category
based
on
duration
of
exposure,
but
the
label
elements
are
the
same.

$
GHS
assumes
that
skin
corrosives
also
cause
severe
eye
damage
and
includes
eye
damage
in
the
hazard
statement.
OPP
does
not,
although
in
practice
he
statements
are
often
combined
for
these

aquatic

In

considered
"
supplemental

consistent
with
but
not
part
of
the

$
The
GHS
has
three
acute
and
four
chronic
categories
for
aquatic
toxicity.
Categories
1­

Category
4
chronic

based
on
persistence
alone,
in
the
absence
of

data.
OPP

a
fish

than
flammability
but
notes
that
when
data
demonstrate
such
hazards,
(
for
example,
explosivity),
appropriate
hazard
statements
must
appear
on
the
label.

Part
2
of
the
GHS
document
specifies
classification
criteria
and
label
elements
for
explosives,
oxidizers,
compressed
gases,
self­
reactive
and
self­
heating
substances,
pyrophoric
liquids
and
solids,
substances
which
emit
flammable
gases
in
contact
with
water,
organic
peroxides,
and
metal
corrosives.

$
To
be
consistent
with
the
GHS,
OPP
would
need
to
adopt
the
GHS
criteria
and
label
elements,
as
well
as
the
associated
test
methods,
for
each
the
physical/
chemical
hazard
class
or
category
it
decides
to
cover.
