  1. Chemical Hygiene Plan Review

  2. Chemical Hygiene Plan CHP Review Objectives • Reduce chances for lab accidents • Avoid unnecessary exposure • Regulation compliance

  3. General Awareness • Chemical Hygiene Plan • Understanding MSDSs

  4. Overview • General Rule and Procedures • Standard Operating Procedures (SOPs) • Housekeeping procedures • Choosing Hazardous Chemicals • Labeling, Storage, and Disposal • Material Safety Data Sheets (MSDSs) • Protective Clothing Requirements • Emergency Procedures

  5. CHP Review shall occur: • In advance of laboratories • Prior to new tasks involving hazardous chemicals

  6. Information and Training • General Awareness • Campus Preparation • Locate Chemical Hygiene Plan • Contains specific hazards, SOP’s, potential exposures, and protective measures • Refer all safety questions to Science Lab Director • Employee Review Record –Maintained on file

  7. Purpose and Policy • Purpose: • Ensure that the hazards are evaluated • Convey information to lab supervisors • Policy: • Employees are entitled to a safe and healthy place to work, and • Have a right to know what you may be exposed to and how to protect yourself

  8. Responsibilities • Develop and implement a written Chemical Hygiene Plan (CHP) • Inventory all hazardous materials in Department and acquire all related Material Safety Data Sheets (MSDSs) • Identify hazards by labeling chemicals • Train employees on physical and health hazards and protective measures

  9. Employee Responsibilities • Follow all procedures and policies relating to chemicals and follow appropriate laboratory procedures and rules as outlined in the CHP • Refrain from lab operations without proper preparation • Seek out and request information • Wear appropriate protective equipment • Report accidents and near-misses immediately, even minor injuries or exposures to the Lab Director

  10. Administrative Controls • Chemical Hygiene Coordinator Duty assignment • Science Lab Director • Ensure lab supervisors know their responsibilities under the Chemical Hygiene Plan

  11. Operational Controls • Basic Standard Operating Procedures • Information Dissemination and Inspections

  12. Basic Standard Operating Procedures • Rules and procedures • Safety Rules and guidelines • Chemical procurement, storage and inventory procedures • Spill and accident procedures • Personal protection apparel and equipment • Information dissemination, documentation • Emergency response

  13. Specific Standard Operating Procedures • Included and specific to each lab procedure • No required format or delivery • Required content: • Hazard controls • Personal protective equipment • Health & safety information • Decontamination & waste disposal procedures

  14. Engineering Controls • Fume Hoods • Biosafety Cabinets • Less hazardous Substitution

  15. “Other” Control Measures • Protective Equipment • Respirators, goggles, gloves, lab coats • Safety Equipment • Safety showers, eyewashes, fire extinguishers, first aid kits, • Laboratory Maintenance and Inspection • Safety inspections, fume hood condition, chemical storage, spill kits, etc.

  16. Exposure Assessments • Policy on monitoring • Signs or symptoms of overexposure • You suspect exposure limits have been exceeded • Determined & carried out by First Responders

  17. Regulated Waste Management • Wastes Considered • Non-Hazardous • Listed/Hazardous • Medical Waste • Universal

  18. Hazardous Chemical Inventories An inventory of chemicals on hand is required.

  19. Hazardous Chemicals Locations On Campus May Include:

  20. Corrosives - Nitric Acid Oxidizers - Silver Nitrate General Organic Compounds - Aniline Caustics - Calcium Oxide Reactive Metals - Sodium Explosive Anhydrides and Anhydrous Compounds - Sodium Peroxide Ketones - Acetone Poisons - Potassium Cyanide General Inorganic Compounds - Calcium Carbide Flammable Metals - Magnesium Flammables - Ethanol, Butanol, Ethyl Ether Carcinogens - Formaldehyde Hazardous Chemicals In Laboratories May Consist Of:

  21. Hazard Communication • Color coded system

  22. Labels - Basics • Identity of the hazardous chemical(s) • chemical label is your primary source of information regarding the product. • Appropriate hazard warnings

  23. Labels &Other Information • Appropriate personal protective equipment • Signal word - Danger!, Warning!, or Caution! • Statement of hazard • Instructions in case of contact or exposure • First-Aid or antidote • Instructions in case of fire, spill, or leak • Instructions for container handling and storage • Never remove label, and if transferred to a secondary container, label the bottle (not the lid) with appropriate information - chemical name, etc.

  24. HMIS Label - Example Secondary Labeling System

  25. Labels- Symbols and Pictures

  26. Material Safety Data Sheets (MSDS’s) • Chemical document put out by manufacturer detailing physical and health hazards • One for every hazardous chemical on campus • Master file located inLab Directors office • Review before working with any chemical

  27. Information on MSDSs • Identity and date of preparation • Manufacturer’s name, address, and telephone number • Hazardous ingredients • Physical and chemical properties - flash pt., appearance and odor, etc.

  28. Information on MSDSs • Control measures • Physical hazards • Routes of entry into body • Acute and chronic health effects • Carcinogenicity • Handling and storage precautions

  29. Chemical Sensitivities • Some hazardous chemicals are used • Immune responses and sensitivities can vary among individuals • Low-dose exposures over longer periods of time can alter function of immune system

  30. Chemical Sensitivities • Effects may develop slowly • Symptoms may include Multiple Chemical Sensitivities, Contact Dermatitis • Examples include – nickel compounds, amines, epoxides, some organic solvents

  31. Protective Measures • Routes of entry • Inhalation • Ingestion • Skin or eye contact, and/or absorption • Exposure = Dose x Duration

  32. Protective Measures • Avoid Inhalation • Use proper ventilation (Fume Hood) • Use respiratory protection (Respirator) • Check MSDS for specific requirements

  33. Protective Measures • Prevent Ingestion • NO eating, drinking, smoking, or applying cosmetics in labs • Wash hands frequently • Label everything • Read labels and MSDSs

  34. Protective Measures • Prevent Skin or Eye Contact • Wear protective equipment • Minimize the area of exposed skin

  35. Protective Measures - Review • Avoid Inhalation • Use proper ventilation • Use respiratory protection when needed • Prevent Ingestion • No eating, drinking, smoking, or apply cosmetics in labs • Wash hands frequently

  36. Protective Measures - Review • Prevent Skin or Eye Contact • Wear protective equipment • Minimize the area of exposed skin

  37. Handle With Caution • Use cautious approach • Read labels, follow their directions • Think about consequences • Treat all substances as if they are hazardous • Practice good chemical hygiene

  38. Emergency Procedures Chemical Spills • Evacuate and call Public Safety at 911 for larger spill (>1-gallon) situations • Treat life threatening injuries immediately • Contain the spill – refer back to MSDS • Wear protective equipment during clean-up • Best response is preparation

  39. Emergency ProceduresPersonal Contamination • Flush contaminated area with water • Remove contaminated clothing • Rinse with water for 15 minutes • Seek medical attention if irritation persists

  40. Emergency ProceduresChemical in the Eye(s) • Flush eyeballs and inner eyelids • Forcibly hold eyes open • Irrigate for at least 15 minutes • Seek medical attention immediately

  41. Summary • You may be exposed to hazardous chemicals or chemicals products used on campus • Information is available on labels and MSDSs • A CHP is in place in your work area to inform you

  42. Chemical Hygiene Review Certification Form By signing below you acknowledge that you are aware of the Chemical Hygiene Plan. I: • know where the Workplace Chemical List/Chemical Inventory is located and understand its purpose. • know how to interpret labels and MSDSs. • know where the Department MSDSs are located. • understand the protective measures, first aid procedures and emergency procedures necessary for the chemicals I use. • know that the Hazardous Materials Safety Manual is available in the Lab Directors office. • understand that there are special procedures and requirements for managing chemical and hazardous waste and that these materials must not be poured down the drain or placed in the regular trash. • understand that the Occupational Safety and Health Administration (OSHA) requires that laboratory workers be made aware of the Chemical Hygiene Plan (CHP) (29 CFR 1910.1450).
