Material Safety Data Sheets MSDS
What is an MSDS Sheet? MSDS Sheet is a technical data sheet detailing the information about chemicals.
Info found on an MSDS Identity- names and chemical abstract service numbers Precautions Proper Storage Physical properties- density, boiling point, appearance Chemical properties- reaction, corrosion, oxidizer
Info found on an MSDS Physical Hazards- fire, explosion Health hazards- irritation, tolerance limit value (TLV), permissible exposure level (PEL) Handling- storage, spills, disposal Control measure- equipment Chemical reactivity- stability, incompatible families of chemicals
Emergency Procedures **Report any injury, accident or spill immediately 1. Thermal burns- immediately apply cold running water to the burned area 2. Chemical burns A. Should any chemical splash in your eye, immediately use a continuous flow of running water to flush eye for 20 min. Remove contact lenses and call for help. B. If any chemical contacts the skin, wash affected area C. If chemicals spill over a large part of body, remove contaminated clothing and take a safety shower
Emergency Procedures 3. All chemical spills need to be cleaned up immediately. If a small spill occurs, wash the area with plenty of water. A spill kit can be used to clean large spills
Emergency Procedures 4. Fire- Turn off all gas outlets and unplug appliances Stop, drop, and roll (fire blanket) Small hair fires can be smothered with a lab notebook Small fires in the lab can be smothered with a blanket Use a fire extinguisher to put out large fires Remember (PPP- Pull, Point, Press) Never use water to put out a fire!!!
Emergency Procedures 5. General First Aid Minor cuts: allow area to bleed for short time and wash with soap and water Poisoning: note what substance was responsible and alert teacher or supervisor; Call poison control
Interpreting Chemical Labels National Fire Safety Agency Diamond Diamonds contain numbers indicating the Hazard Rating Index in the Hazard Coding System The NFPA Diamond uses color codes to identify Health risks (in blue), Flammability (in red), Instability (in yellow), and Special Hazards (in white). It rates the severity of the hazard on a scale of 0 to 4 with 4 being the most severe.
Hazard Coding System Fire Hazard (Red) Flash Points 4 - Below 73 F 3 - Below 100 F 2 - Below 200 F 1 - Above 200 F 0 - Will not burn Health Hazard (Blue) 4 - Deadly 3 - Extreme Danger 2 - Hazardous 1 - Slightly Hazardous 0 - Normal Material Instability (Yellow) 4 - May Dentonate 3 - Shock and Heat May Detonate 2 - Violent Chemical Change 1 - Unstable if Heated 0 – Stable Specific Hazard (White) Oxidizer ---- OXY Acid ---- ACID Alkalai ---- ALF Corrosive ---- COR Use No Water ---- Radiation Hazard ---- Polymerizes ---- P No special hazard ----
