5. a) PURPOSE
• All hazards to be CLASSIFIED not Evaluated
• "Classification" means to identify the relevant data regarding the
hazards of a chemical; review those data to ascertain the hazards
associated with the chemical; and decide whether the chemical
will be classified as hazardous according to the definition of
hazardous chemical in this section. In addition, classification for
health and physical hazards includes the determination of the
degree of hazard, where appropriate, by comparing the data with
the criteria for health and physical hazards.
• "Hazard class" means the nature of the physical or health
hazards, e.g., flammable solid, carcinogen, oral acute toxicity.
6. b) SCOPE AND APPLICATION
• All chemicals known to be present are covered.
• Practical accommodations for special situations
• Address interface with other Federal laws.
7. c) DEFINITIONS
• Physical hazard definitions removed and placed in new
Appendix B
• Deleted terms: flashpoint, hazard warning, material safety
data sheets.
• Some definitions were revised to be consistent with the GHS.
• New definitions added for classification.
• Signal Word - means a word used to indicate the relative level
of severity of hazard and alert the reader to a potential hazard
on the label. The signal words used in this section are
"danger" and "warning." "Danger" is used for the more severe
hazards, while “Warning" is used for the less severe.
8. d) HAZARD CLASSIFICATION
• Chemical manufacturers and importers shall evaluate
chemicals produced in their workplaces or imported by
them to classify the chemicals in accordance with this
section. For each chemical, the chemical manufacturer
or importer shall determine the hazard classes, and
where appropriate, the category of each class that apply
to the chemical being classified. Employers are not
required to classify chemicals unless they choose not to
rely on the classification performed by the chemical
manufacturer or importer for the chemical to satisfy this
requirement.
9. e) WRITTEN HAZARD
COMMUNICATION PROGRAM
• Employers must have a written program describing how
the rule will be implemented, including a list of
hazardous chemicals, methods for informing employees
about non-routine tasks.
• Employers must make sure the program is current when
the new provisions are implemented (e.g., list of
hazardous chemicals may have to be updated).
10. f) LABELS AND OTHER FORMS OF
WARNING
• Shipped containers to be labeled with product identifier;
signal word; hazard statement(s); pictograms;
precautionary statements; and responsible party.
• Specifies information by hazard class and category
• Appendix “C” is a cookbook approach for labeling.
11. LABEL REQUIREMENTS – SHIPPING
CONTAINERS
• Product identifier
• Signal word
• Hazard statement(s)
• Pictogram(s)
• Precautionary statement(s)
• Name, address, and phone number of the responsible
party.
21. EXCLAMATION MARK
• Irritant (skin and eye)
• Skin Sensitizer
• Acute Toxicity
• Narcotic Effects
• Respiratory Tract Irritant
• Hazardous to Ozone Layer

24. WORKPLACE LABELING
• Same workplace –specific labeling.
• Make sure the labeling system is updated to be
consistent with the new classifications.
• NFPA/HMIS Systems - NO
• (rating systems v. classification)
• GHS and NFPA/HMIS Reversed
25. SECONDARY LABELING
• Employers have more flexibility. The basic requirement for workplace
labeling is as follows:
• “the final rule retains the flexibility by indicating that the employer can
choose to label workplace containers either with the same label that would
be on shipped containers for the chemical under the revised rule, or with
label alternatives that meet the requirements for the standard.”
• The HCS 2012 specifically states for workplace container labeling that
labels must contain GHS label elements (pictograms, etc.) OR
• “Product identifier and words, pictures, symbols, or combination thereof,
which, in conjunction with the other information immediately available to the
employee under the HC program, will provide employees with the specific
information regarding the physical and health hazards of the hazardous
chemical.”
26. g) SAFETY DATA SHEETS
• Mandates 16-section SDS headings, order of
information, and what information is to be provided under
the headings.
• Will not enforce sections 12-15 that require information
outside OSHA’s jurisdiction.
27. 16- SECTION SAFETY DATA SHEET
1. Identification of the substance or
mixture and of the supplier
10. Stability and reactivity
2. Hazard identification 11. Toxicological

6. Accidental release measures 15. Regulatory information
7. Handling and storage 16. Other information including
information on preparation and
revision of the SDS
8. Exposure controls/personal
protection
9. Physical and chemical properties
28. h) EMPLOYEE INFORMATION AND
TRAINING
• Clarifies that the labels on shipped containers and
workplace labels must be explained, as well as SDS
format.
• Workers will have to be trained on the new label and
SDS formats before all the provisions of the rule are
effective.
29. TRAINING, CONTINUED
• Labeling elements
• Train the employees on the type of information that the employee
would expect to see on the new labels.
• How they might use that information
• Product identifier, Signal Word, hazard statement(s), pictogram(s),
precautionary statement(s), and name, address and phone number of
the responsible party.
• General understanding of how the elements interact
• For example – explain there are two signal words: Danger means a more
severe hazard within a hazard class. Warning is for less severe hazard.
• Safety Data Sheet
• Train the employees on the standardization 16 section format and the
type of information they would find in the various sections.
30. i) TRADE SECRETS
• Allows specific chemical identity to be protected when it
is a legitimate trade secret.
• Specifies conditions for protection or for release when
there is a safety and health need for information.
• The percentage of a substance in a mixture is also
considered to be a type of trade secret subject to the
provisions in the rule.
31. COMPLIANCE DATES
• Became effective May 25, 2012
• Employees to be trained by December 1, 2013
• Update alternative workplace labeling and hazard
communication program as necessary by June 1, 2016

No ignition source (flame is necessary)
Mixing concentrated hydrogen peroxide with an organic material, in the presence of a catalyst will react on its own, causing a very hot flame.
Bread with drops of peroxide + leather = hot flame
Class Rating Hazard Description
Class 1 An oxidizing material whose primary hazard is that it may increase the burning rate of combustible material with which it comes in contact.
Class 2 An oxidizing material that will moderately increase the burning rate or which may cause spontaneous ignition of combustible material with which it comes in contact.
Class 3 An oxidizing material that will cause a severe increase in the burning rate of combustible material with which it comes in contact or which will
undergo vigorous self-sustained decomposition when catalyzed or exposed to heat.
Class 4 An oxidizing material that can undergo an explosive reaction when catalyzed or exposed to heat, shock or friction.

Pyrophoric chemicals are liquids and solids that will ignite spontaneously in air at about 130 degrees F.
Titanium dichloride and phosphorus are example of pyrophoric solids; tributylaluminum and related compounds are examples of pyrophoric liquids.
From Wikipedia on organic peroxides:
In polymer chemistry
Organic peroxides find numerous applications, often involving similar chemistry. Thus, peroxides serve as accelerators, activators, cross-linking agents, curing and vulcanization agents, hardeners, polymerisation initiators, and promoters. Drying oils, as found in many paints and varnishes function via the formation of hydroperoxides.
Methyl ethyl ketone peroxide, benzoyl peroxide and to a smaller degree acetone peroxide are used as initiators for radical polymerization of some resins, e.g. polyester and silicone, often encountered when making fiberglass.
Self-reactive Substances
What are unstable chemicals?
Unstable or self-reactive substances are chemicals which have the potential to vigorously polymerize, decompose, condense, or become self-reactive under conditions of shock, pressure, temperature, light, or contact with another material. Major types of highly reactive chemicals are explosives, peroxides, water-reactives, and pyrophorics.
What should I do when handling unstable chemicals?
• Always wear safety goggles, closed toe shoes, and gloves
• Handle under a hood if the reaction has the potential of creating gases
• If there is a chance of explosion, use barriers or other forms of isolation methods
• For some heat sensitive materials, temperature should be controlled.
• Date all containers when received or opened
Acids have better warning properties than bases. Acids will burn quickly, the victim will seek water, FAST.
Caustics, poor warning properties: slippery feeling, break down proteins in the skin.
