  1. LABORATORY STANDARD 29 CFR 1910.1450 OVERVIEW • APPLIES TO ALL EMPLOYEES ENGAGED IN THE USE OF HAZARDOUS CHEMICALS IN A LABORATORY

  2. LABORATORY STANDARD OVERVIEW • Chemical Hygiene Plan • Hazard Communication Training • MSDS Sheets • Chemical Storage and Labeling • Emergency Procedures • Personal Protective Equipment • Employee Training • Laboratory Safety

  3. Chemical Hygiene Plan • Prepare written plan • Assign Chemical Hygiene Officer (CHO) • Establish Chemical Hygiene Committee • Hold regular safety meetings • Establish procedures to ensure a safe working environment

  4. Hazard Communication • OSHA created the hazard communication standard (1910.1200) to ensure the safety of the employee when working with hazardous chemicals. • This allows the employee to be informed about the chemicals they work with and how to safely use them

  5. Health Hazards • Carcinogens • Cancer causing agents • Example- Gasoline • Corrosives • Causes visible destruction or irreversible alterations in living tissue • Example- Toilet Bowl Cleaners • Toxic • A chemical that has a lethal dose of 50 milligrams • Example- Mercury • Irritants • Causes a reversible inflammatory effect on living tissue • Example- Bleach • Sensitizer • Allergic reactions occur from repeated exposure • Example - New Carpet Odor

  6. Physical Hazards • Flammable/Combustible Liquids • Have low melting, boiling, and ignition temperatures • Example- Paints and Thinners • Compressed Gasses • Gases stored under an elevated pressure • Example- Carbon Dioxide • Flammable Solid • Causes fire through friction, absorption, and burns vigorously • Example- Sodium • Water Reactive • A chemical that reacts with water to release a gas that is hazardous • Example- Potassium • Oxidizer • A chemical that initiates or promotes combustion of other materials through the release of oxygen • Example- Ammonium Nitrate

  7. Routes of Entry • INHALATION HAZARDS • MISTS, FUMES, FIBERS, SMOKE, DUST • USE VENTILATION / RESPIRATORY PROTECTION • SKIN ABSORPTION HAZARDS • CHEMICALS LIKE GASOLINE, SOLVENTS, THINNERS • WEAR PPE – GLOVES, SLEEVES, APRON, FACE SHIELD • INGESTION HAZARDS • CHEMICALS TRANSFERRED TO FOOD OR DRINK • WASH HANDS, NEVER HAVE FOOD OR DRINK IN AREAS WITH CHEMICALS

  8. TYPES OF FIRES • A • NORMAL TRASH, PAPER, WOOD • B • FLAMMABLE LIQUIDS • C • ELECTRICAL • D • METAL

  9. TYPES OF FIRE EXTINGUISHERS • WATER • CO2 • DRY CHEMICAL • FOAM • DRY POWDER

  10. Annual check-up and recharge Monthly visual inspection initial tag Properly mounted (secured) handle between 3’ 6” and 5’ from ground Location Identified e.g. Signage, color coded. etc. Extinguisher Identified type - letter, symbol or both Easily accessible, unobstructed Requirements for Fire Extinguishers

  11. Material Safety Data Sheets • Section I - Material Identification • Section II - Hazardous Ingredients/Identity • Section III - Physical/Chemicals Characteristics • Section IV - Fire and Explosion Hazard Data • Section V - Reactivity Data • Section VI - Health Hazard Data • Section VII - Precaution for Safe Handling and Use • Section VIII - Control Measures

  12. MATERIAL LABELING • ALL CONTAINERS OF HAZARDOUS CHEMICALS MUST HAVE • PRODUCT OR MATERIAL NAME • HAZARDS OF PRODUCT OR MATERIAL • MANUFACTURER ( IF POSSIBLE )

  13. LABELING SYSTEMS • NATIONAL FIRE PROTECTION ASSOCIATION (NFPA) • HEALTH 0-4 • BLUE • FIRE 0-4 • RED • REACTIVITY 0-4 • YELLOW • SPECIFIC HAZARD • WHITE 4 = Extreme 3 = Serious 2 = Moderate 1 = Slight 0 = Minimal

  14. LABELING SYSTEMS • HAZARDOUS MATERIAL IDENTIFICATION SYSTEM (HMIS) • HEALTH 0-4 • BLUE • FIRE 0-4 • RED • REACTIVITY 0-4 • YELLOW • PROTECTIVE EQUIPMENT A-K, X • WHITE 4 = Extreme 3 = Serious 2 = Moderate 1 = Slight 0 = Minimal

  15. A) SAFETY GLASSES B) SAFETY GLASSES, GLOVES C) SAFETY GLASSES, GLOVES, APRON D) FACE SHIELD, GLOVES, APRON E) SAFETY GLASSES, GLOVES, DUST RESPIRATOR F) SAFETY GLASSES, GLOVES, APRON, DUST RESPIRATOR G) SAFETY GLASSES, GLOVES, VAPOR RESPIRATOR H) SPLASH GOGGLES, GLOVES, APRON, VAPOR RESPIRATOR I) SAFETY GLASSES, GLOVES, DUST/VAPOR RESPIRATOR J) SPLASH GOGGLES, GLOVES, APRON, DUST/VAPOR RESPIRATOR K) AIRLINE/SCBA, GLOVES, PROTECTIVE SUIT, BOOTS X) SPECIFIC PPE SEE YOUR SUPERVISOR HMIS PPE LABELING SYSTEM

  16. CHEMICAL STORAGE • STORE CHEMICALS ACCORDING TO A DESIGNATED SYSTEM THAT SEGREGATES INTO FAMILIES • FLAMMABLE / COMBUSTIBLE LIQUIDS • OXIDIZERS • REACTIVES • FLAMMABLE SOLIDS • ACIDS • ALKALINES • POISONS / TOXICS

  17. Improper Chemical Storage • No storage pattern • No lips on shelves • Chemical in red bag is a flammable chemical • A chemical is stored above eye level (top shelf)

  18. Proper Chemical Storage • 1/4” lips on shelves • Bottles color coded to match proper location on shelf (Flinn System) • Proper chemical labeling • Containers in good condition

  19. FLAMMABLE/COMBUSTIBLE CHEMICALS ARE REQUIRED TO BE STORED IN APPROPRIATE FIRE RATED CABINETS ACIDS ARE RECOMMEDED TO BE STORED IN APPROPRIATE “ACID” CABINET NITRIC ACID SHOULD BE STORED IN INSULATED CONTAINER (i.e. STYROFOAM CONTAINER FOOD AND CHEMICALS ARE NOT TO BE STORED TOGETHER CHEMICAL CONTAINERS ARE TO BE KEPT IN GOOD CONDITION CHEMICAL SEGREGATION

  20. COMPRESSED GAS STORAGE • COMPRESSED GAS CONTAINERS MUST BE SECURED TO PORTABLE CART OR WALL • CONTAINER MUST BE PROPERLY LABELED • SHOULD BE STORED IN LOW TRAFFIC OR NO TRAFFIC AREA
