MSDS = Material Safety Data Sheet The MSDS lists the chemical ingredients of the substance. Some list only the dangerous chemicals, while others list every ingredient, even if the chemical is not hazardous. MSDS

The Purpose of a MSDS is to tell you…. Material’s Physical Properties Health Hazard Data Fire and Explosion Data Reactivity Data Spill & Leak Procedures Special Protection Information & protective gear needed Special Precautions / How to respond to accidents. Company Info for phone # of emergency contacts

Who Supplies MSDS to Product Users? All manufacturers of hazardous chemicals are required to provide one of these sheets for all products which they sell http://www.med-chem.com/MSDS/100_iso.htm

Your Employee Rights & Student Rights Your employer must have an MSDS for every hazardous substance that you use as part of your job These MSDS’s must be available to you in the workplace If you request to see a copy of an MSDS for a product you use and it is not provided in 1 working day, then you may refuse to work with the product in the area that it is used If requested, your employer must provide a personal copy of an MSDS within 15 working days

Labeling and Marking Systems All chemical containers must be labeled Acceptable systems include NFPA-704 diamonds (National Fire Protection Agency) HMIS labels (Hazardous Materials Identification System) Manufacturer’s original label Other

Labeling and Marking Systems NFPA-704 Diamonds Color coded & numerical rating system Provide at-a-glance hazard information

Labeling and Marking Systems NFPA-704 Diamonds Blue = Health Red = Flammability Yellow = Reactivity White = Special hazard information

Labeling and Marking Systems NFPA-704 Diamonds 4= Deadly Hazard 3= Severe Hazard 2= Moderate Hazard 1= Slight Hazard 0= No Hazard

HEALTH 4 Deadly: Slightest exposure to this substance would be life threatening. Only specialized protective clothing should be worn. 3 Extreme Danger: Serious injury from exposure to this substance. Do not expose any body surface to these materials. Follow full protective measures. 2 Dangerous: Exposure would be hazardous to health. Protective measures indicated. 1 Slight Hazard: irritation or minor injury would result from exposure to this substance. Protective measures are indicated. 0 No Hazard: exposure to this substance offers no significant risk to health.

FLAMMABILITY 4 Very Flammable, volatile or explosive depending on its state: Flash Point below 73ºF & Boiling Point below 100ºF. Extreme caution should be used in handling or storing of these materials. 3 Flammable, volatile or explosive under normal temperature conditions: Flash Point Below 100ºF. Exercise great caution in storage or handling. 2 Moderately heated conditions may ignite this substance: Flash Point Below 200ºF. Caution in handling. 1 Combustible, must be preheated to ignite: Flash Point Above 200ºF. Most combustible solids fit this category. 0 Will Not Burn

INSTABILITY 4 May Detonate: capable of detonation or explosion at normal temperatures and pressures. Evacuate area if exposed to heat or fire. 3 Explosive: capable of detonation or explosion by a strong initiating source, such as heat, shock or water. Monitor from behind explosion-resistant barriers. 2 Unstable: violent chemical changes are possible at normal or elevated temperatures and pressures. Potentially violent or explosive reaction may occur when mixed with water. Monitor from a safe distance. 1 Normally Stable: may become unstable at elevated temperatures and pressures or when mixed with water. Approach with caution. 0 Stable: remain stable when exposed to heat, pressure or water.

Labeling and Marking Systems HMIS Labels Designed to go on individual containers of products that don’t have manufacturer’s labels Same color code /numerical rating system as the NFPA diamonds

Labeling and Marking Systems HMIS Labels Blue = Health Red = Flammability Yellow = Reactivity White = Personal Protective Equipment or special protection information Indicates numerical Hazard Rating of 0-4
