Worker and Community Right to Know Act
Enacted October 4, 1984
Gives employees access to information about hazardous substances

Seven Important Provisions of the Right to Know Act
1. Creates a list of 2336 chemicals that are defined as hazardous substances
![Page 4: 2013Q1](https://reader036.fdocuments.us/reader036/viewer/2022062723/56813c88550346895da62980/html5/thumbnails/4.jpg)

Seven Important Provisions of the Right to Know Act, continued…
4. Requires that a MSDS (material safety data sheet) for each substance be made readily accessible to you. The MSDS tells you about the hazards of a substance and what you can do to reduce those hazards

Seven Important Provisions of the Right to Know Act, continued…
7. Allows you to refuse to work with a hazardous substance if we fail to provide you or your representative with an MSDS, or fail to furnish proof of a diligent effort to obtain the MSDS

Right to Know Act Exemptions Chemicals used in
research, teaching and testing laboratories, or chemical storage areas are not required to be on the list of hazardous substances.

About the MSDS
Section OneManufacturer’s name, address, emergency
telephone numberChemical name, trade name, synonyms,
chemical abstract service number (CAS#)The CAS number is a unique number assigned to each
chemical (similar to a social security number) that helps differentiate between chemicals with similar names
![Page 13: 2013Q1](https://reader036.fdocuments.us/reader036/viewer/2022062723/56813c88550346895da62980/html5/thumbnails/13.jpg)
MSDS
Section Two: Hazardous IngredientsLists hazardous ingredients and the percentage
of each in the substanceTLV (Threshold Limit Value), the concentration of
a substance believed to be safe for a person to be exposed to for 8 hours/day, 40 hours/week. Established by the American Conference of Governmental Industrial Hygienists (ACGIH) May also be listed as a OSHA PEL (Permissible Exposure
Limit) or a NIOSH REL (Recommended Exposure Limit)

MSDS
Section Two: Hazardous IngredientsExposure Limits are typically expressed in parts
per million (ppm)For comparison purposes:
1 part per million = 1 inch in 16 miles

MSDS
Section Three: Physical Data Physical Characteristics
State of matter (solid, liquid, gas) Color Odor Taste (not generally a good idea!)
Boiling point (temperature where material begins to boil) Vapor pressure (Measure of evaporation rate) Vapor density (Sink or rise in air?) Solubility (Dissolve in water?) Specific gravity (Sink or float in water?) Volatility (Tells how much will evaporate) Evaporation rate (high # = evaporate fast)

Section 5: Exposure & Health EffectsCan cause harm in a variety of waysDoes not always have harmful effectsFactors determine whether you will be harmed:
concentration of the substancepersonal susceptibility to the substancehow contact with the substance occurs
![Page 19: 2013Q1](https://reader036.fdocuments.us/reader036/viewer/2022062723/56813c88550346895da62980/html5/thumbnails/19.jpg)
Possible Effects from Exposure
Acute - immediate reaction to short term exposure
Chronic - develop slowly over a long period of time
Carcinogen - causes cancer
Mutagen - causes a change in the genetic material in human cells
Teratogen - causes damage to a fetus

Contact

Contact continued…Swallowing
Can happen by handling chemicals then eating without washing your hands.
So always remember to wash your hands directly after being exposed to hazardous chemicals.

How to Get MSDSs
Each Station, the Administration office and the Fire Shop, should have copies of the MSDS sheets for the items in that facility.
![Page 27: 2013Q1](https://reader036.fdocuments.us/reader036/viewer/2022062723/56813c88550346895da62980/html5/thumbnails/27.jpg)
Conclusion
Always read labels and follow the instructions on them
You should know about the potential hazards of substances in your workplace.
Working together we can make our workplace as safe as possible
If you are unable to identify the product or locate a MSDS sheet, contact your station/shift safety representative.
