Chemical Labeling Information
Reagent bottle labels produced by the HSU Chemistry
Department stockroom have the following information and appearance:
Items 2 - 4 should appear on all chemical container
labels produced by students as well.
1. JT Baker Chemical SAF-T-DATA Rating
System (Not Required) The Chemistry Department at HSU has
chosen to provide this information as a guide when it is available.
2. Chemical Name (must be spelled out)
formula is acceptable only as an addition.
3. Physical State (Solid,Liquid,Gas)
and Concentration (if liquid).
4. In addition: If used as a reagent
by more than one individual or left longer than 24 hours the following:
Warning words indicating the particular hazards such as Corrosive,
Flammable, Poison (Toxic); Target Organs; Physical State (Solid,
Liquid, Gas); Contents/Composition and their approximate proportions
Corrosive. [22 CCR 66261.22]
- It is aqueous and has a pH equal to or less than 2, or equal
to or greater than 12.5, or by mixture with an
equivalent weight of water it produces a solution with those
- It is a liquid (or when mixed with an equivalent weight of
water it produces a liquid) and corrodes steel
(SAE 20) at a rate greater than 0.250 inch (6.35 millimeters)
Poison/Toxic . [22 CCR 66261.24]
- When analyzed by a state certified laboratory, it is determined
to exceed the regulatory levels established for the inorganic
or organic chemicals found in Table II or Table III of 22 CCR
- It contains the California listed carcinogenic substances
in single or combined concentration of 0.001% by weight by testing
or other information available.
- It is determined by biological tests to be more toxic than
any of the following: an oral Singe Dose of less than 5,000 mg/Kg
which on the basis of laboratory tests, is expected to kill 50%
of the test species; a Singe Dose applied to the skin of less
than 4,300 mg/Kg which, on the basis of laboratory tests, is
expected to kill 50% of thetest species; a single exposure (usually
of 1 to 4 hours) with a concentration in air of less than 10,000
ppm which , on the basis of laboratory tests, is expected to
kill 50% of the test species ; a single 96 hours exposure with
a concentration in air of less than 500 mg/L which, on the basis
of laboratory tests, is expected to kill 50% of the test species;
or it can cause illness or death if inhaled, swallowed
or absorbed through the skin.
- For a liquid- the vapor above it with air will ignite if
supplied with a source of ignition at a temperature below 100
degrees F and and it has a vapor pressure of less than 40 psi
at 100 degrees F.
- For a solid- any solid material other than an explosive that
can cause fire through friction or retained heat from manufacturing
or processing. Any solid that can readily be ignited and, when
ignited can burn so vigorously and persistently as to create
a serious hazard during transportation or storage.
