The Federal OSHA Standards, 29 CRF 1910 and 1926,
better known as the Hazard Communications or
Right-to-Know standards, apply to the state
government and its political subdivision.

Material Data Safety Sheet (MSDS)

• MSDS of a chemical describes the physical and
  chemical properties, physical and health hazards,
  routes of exposure, precautions for safe handling
  and use, emergency and first aid procedures, and
  control measures.
• Each workplace is required to have MSDS available
  for every single hazardous chemical or substance
  you use or encounter as part of your job.

4
Hazardous Substance

• OSHA has classified chemicals that have the
  potential to cause acute or chronic health
  effects as health hazards. These include
• Carcinogens formaldehyde
• Corrosives phenol
• Hepatotoxins chloroform
• Mutagens ethidium bromide
• Neurotoxins acrylamide
• Teratogens - formamide

5
Material Data Safety Sheet (MSDS)

• At a minimum the MSDS are required to have the
  following
• Section I. Chemical Identity
• Section II. Hazardous Ingredients
• Section III. Health Hazards
• Section IV. First Aid Measures
• Section V. Fire Explosion Hazard Data
• Section VI. Accidental Release Measures
• Section VII. Precautions for Safe Handling and
  Use
• Section VIII. Control Measures

6
Material Data Safety SheetChemical Product
Company Information

• MSDSs must be in English and include the
  following information
• The identity of the material, including the
  identity on the label, the chemical and common
  name(s), and the Chemical Abstract Service
  Registry (CAS) number(s)
• The name, address, and telephone number of the
  manufacturer, importer, employer, or other
  responsible party who can provide additional
  information or assistance for emergency
  procedures, or as otherwise necessary.

7
Material Data Safety Sheet Physical and Chemical
Properties

• The physical and chemical properties include
• Appearance
• Odor
• Physical state
• pH
• Vapor pressure
• Vapor density
• Boiling point
• Freezing/melting point
• Solubility in water
• Specific gravity or density.

• Stability and Reactivity
• Disclosure of potential reactivity hazards is
  required in an MSDS. This is often accomplished
  by describing the conditions that could result in
  a potentially hazardous chemical reaction. The
  following information could be included
• Chemical stability
• Conditions to avoid
• Incompatibility with other materials
• Hazardous decomposition products
• Hazardous polymerization.

8
Material Data Safety Sheet Hazard Identification

• Potential Health Effects
• Exposure to the material and its components
  during customary and reasonably foreseeable use,
  misuse, handling, and storage. It must include
  the following elements
• Relevant route(s) or exposure
• Lengths of exposure
• Severity of the effect
• Target organ(s)
• Type of effect
• Signs and symptoms of exposure
• The chemical carcinogenicity status
• Medical conditions known to be aggravated by the
  exposure to the material.

9
Material Data Safety Sheet Hazard Identification

• First Aid Measures
• Instructions on providing immediate treatment
  before professional medical help is available. It
  should also indicated whether immediate medical
  attention is required and if delayed effects can
  be expected after exposure.When there is no
  specific information available, the following
  information may be included
• Removal of exposed individuals from the area
• Removal of material from the individual
• Advice on removal and handling of contaminated
  clothing and shoes
• Advice on whether immediate medical attention is
  necessary.

10
Material Data Safety SheetHazard Control

• Fire-fighting Measures Overview
• The fire and explosive properties of the material
  
• Appropriate extinguishing media
• Basic fire-fighting guidance.
• Flash point and method
• Upper and lower explosive limits (UEL and LEL) in
  air
• Flammability classification
• Flame propagation or burning rate of solid
  materials
• Known or anticipated hazardous products of
  combustion
• Properties of both flammable and nonflammable
  materials that may initiate or uniquely
  contribute to the intensity of a fire
• Potential for dust explosion
• Reactions that release flammable gases or vapors
• Fast or intensely burning characteristics
• Release of invisible flammable vapors.

11
Material Data Safety Sheet Hazard Control

• Accidental Release Measures  
• This section contains information for responding
  to spills, leaks, or releases in order to
  eliminate or minimize the adverse effects on
  persons, property, and the environment.The
  following types of information should be
  included
• Containment techniques (e.g., diking or capping
  procedures)
• Cleanup procedures (e.g., neutralization and
  decontamination techniques, sorbent materials,
  sweeping or vacuuming techniques)
• Equipment and other emergency advice relating to
  spills and releases.

12
Material Data Safety Sheet Hazard Control

• Exposure Controls/Personal Protection
• This section of the MSDS will include
  information on the controls necessary to help
  reduce the risk of personnel exposure, including
  
• Guidance for the selection of PPE for each route
  of exposure, and for the use of special PPE
  (e.g., SCBAs) in the event of an emergency
• Engineering controls (e.g., local exhaust system)
  to minimize potential airborne contaminants
• Work practices to reduce the possibility of
  contact or exposure.

13
Material Data Safety Sheet Additional Information

• The MSDS includes the preparation date of the
  document, the last change to it, the OSHA
  Permissible Exposure Limits (PELs), ACGIH
  Threshold Limit Values (TLVs), and any other
  recommended exposure limit, if available.
• Toxicological Information
• Disposal Consideration
• Ecological Information
• Transportation
• Regulation Information

14
Toxicology Terms

• Acute toxicity
• Single short exposure
• Effects usually appear quickly
• Effects often reversible

• Chronic toxicity
• Repeated exposure
• Effects usually delayed
• Usually irreversible

• LD 50 In tests for lethality, the dose at which
  50 of the test animals are killed,
  usually expressed in mg./kg.
• LC 50 For for inhalation hazards, usually
  expressed in mg./m.3

Toxicology Signal Words
16
Labeling and Marking Systems

• In addition to the manufacturers labels, which
  are provided on most chemical products, there are
  also the
• National Fire Protection Association (NFPA)
  diamonds
• Hazard Assessment Signage Program (HASP) system

17
NFPA Diamonds

• A NFPA diamond is located on the door of the
  storage room.
• Blue Health Hazard
• Red Flammability
• Yellow Instability
• White Special Hazard Information

18
HASP Signage

• Laboratories should be marked with the
  appropriate pictographic symbols to warn
  employees, visitors, and emergency responders
  what hazards to expect upon entering the
  laboratory, as well as what precautions should be
  observed
