## Annual Refresher Training	

## 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.

## 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

## 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

## Material Data Safety SheetChemical 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.

## 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.

## 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.

## 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.

## Material Data Safety SheetHazard 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.

## 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.

## 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.

## 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

## Toxicology Terms

**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

**Acute toxicity:**
- Single short exposure
- Effects usually appear quickly
- Effects often reversible

**Chronic toxicity:**
-   Repeated exposure
-   Effects usually delayed
-   Usually irreversible

## Toxicology Signal Words

## Labeling and Marking Systems

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

## 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

## 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
