Safety Data Sheet (SDS) including the
information found in each section.
* The relationship of the information
on the label to the information on the
SDS. If there is similar precautionary
information on the SDS and the label,
the most protective information is to be
placed on the label. OSHA says that the
precautionary information on the SDS
and the label should be the same.
* How the labels could be used in the
workplace. Examples might be that the
information on the label could be used
to locate first aid information quickly
(section 4) or information on the label
could be used to ensure proper storage
(section 7).
Safety Data Sheets (SDS) sections are:
Section 1. Identification
Section 2. Hazard(s) identification
Section 3. Composition/information on
ingredients
Section 4. First aid measures
Section 5. Fire-fighting measures

Section 6. Accidental release measures
Section 7. Handling and storage
Section 8. Exposures controls/personal
protection
Section 9. Physical and chemical properties
Section 10. Stability and reactivity
Section 11. Toxicological information
Section 12. Ecological information (Nonmandatory)
Section 13. Disposal considerations
(Non-mandatory)
Section 14. Transport information (Nonmandatory)
Section 15. Regulatory information
(Non-mandatory)
Section 16. Other information
The SDS may not contain every
item on the list for Section 9 (Physical
and Chemical Properties) because the
information may not be relevant or is not
available. When this situation occurs, a
notation to that effect must be made for
the missing chemical property. Manufacturers may also add other relevant

properties, such as the dust deflagration
index (Kst) (the relative explosion severity compared to other dusts). The dust
deflagration index is used to evaluate a
dust's explosive potential. The higher the
Kst the more severe the explosion will
be.
Additionally, because other agencies
(DOT, EPA, etc.) regulate the information
in Sections 12-15, OSHA will not enforce
these sections (29 CFR 1910.1200(g)(2)
in the Safety Data Sheets (SDS).
Safety Data Sheets, previously referred to as Material Safety Data Sheets,
as described, require a 16-section format
that is essentially the same as the ANSI
standard for Hazardous Workplace
Chemicals--Hazard Evaluation and
Safety Data Sheets and Precautionary
Labeling Preparation (ANSI Z400.1 &
Z129.1 - 2010).
The HCS has always been a fairly
complex regulation, and only a few major changes are highlighted here. Review
