1 Chemical Hygiene and Lab Safety Training Program

2 Texas Tech UCLA Lab accidents

3 Lab accidents and universites  Since 2001, more than 120 university lab accidents have caused injuries, millions of dollars in damages, and one death, according to the federal Chemical Safety & Hazard Investigation Board (CSB).Chemical Safety & Hazard Investigation Board  Based on 2010 OSHA personal injury rate data, it’s about seven times safer to work in a Dow laboratory than a university or college laboratory

4 Chemical Hygiene Plan Training Objectives Reduce number of lab accidents Achieve OSHA compliance

5

6 General Awareness Session Chemical Hygiene Plan Understanding SDSs

7 Training Overview oPurpose and Policy and Responsibilities oHazardous Chemicals on Campus oLabeling, Storage, and Disposal oMaterial Safety Data Sheets (MSDSs) oInformation and Training oEmergency Procedures and Control Measures oStandard Operating Procedures (SOPs) oExposure Monitoring and Medical Attention

8 Before personnel are assigned to laboratory Prior to new tasks involving hazardous chemicals Training shall occur:

9 This Chemical Hygiene Plan Training is not designed to: Satisfy all required elements of the Lab Standard Provide detailed safety training

10 YSU Chemical Hygiene Plan

11 Purpose and Policy Purpose: Ensure that the hazards are evaluated Convey information to employees Policy: You 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

12 Employer Responsibilities Develop and implement a written Chemical Hygiene Plan (CHP) Inventory all hazardous materials on campus and acquire all necessary Material Safety Data Sheets (MSDSs) Identify hazards by labeling chemicals using MSDSs Train employees on physical and health hazards and protective measures Provide medical monitoring for employees

13 Employee Responsibilities oFollow all procedures and policies relating to chemicals and follow appropriate laboratory procedures and rules as outlined in the Chemical Hygiene Plan oRefrain from operations without proper instruction and/or authorization oSeek out and request information oWear appropriate protective equipment oReport accidents and near-misses immediately, even minor injuries or exposures

14 Administrative Controls Assign a Chemical Hygiene Officer Manager of Environmental Health and Safety Ensure lab supervisors know their responsibilities under the Chemical Hygiene Plan

15 Operational Controls Generic Standard Operating Procedures Specific Standard Operating Procedures

16 Generic Standard Operating Procedures Developed by the Chemistry Department Included in the Chemical Hygiene Plan: Chemical storage Using compressed gases Emergency response

17 SOP’s General Waste Disposal Procedures Disposal of Empty Chemical Containers Disposal of Laboratory Glass Waste Dispensing Liquid Nitrogen Spot Check of Air Flow in Fume Hoods Spill Response SOP Transporting Chemicals Methylene Chloride SOP Peroxide Forming Chemicals Gas Cylinder Usage Lab Signage Safety Data Sheets Emergencies

18 Specific Standard Operating Procedures Lab employees write them Specific to each experimental procedure No required format Required content: Hazard controls Personal protective equipment Health & safety information Decontamination & waste disposal procedures

19 Engineering Controls Fume Hoods Biosafety Cabinets Substitution

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

21 Regulated Waste Management Wastes Considered Non-Hazardous Hazardous Liquid Industrial Universal

22 Hazardous Chemical Inventories An inventory of hazardous chemicals is kept for each lab

23 Hazardous Chemicals Locations On Campus May Include:

24 Hazardous Chemicals In Laboratories May Consist Of: 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

25 Labels - Basics Identity of the hazardous chemical(s) Appropriate hazard warnings Name, address, and emergency telephone number of the chemical manufacturer or other responsible party

26 Labels - Other Information Appropriate protective equipment Carcinogenicity warning if applicable 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 it with appropriate information - chemical name, etc.

27 HMIS Label - Example Secondary Labeling System

28 Globally Harmonized System

29 29 Routes of Exposure Inhalation - Most common route of exposure, lungs are designed for maximum transport and adsorption of vapors, large surface area (1000 sf) Dermal – Second most common route of exposure, lipid (pass with greater ease) and water soluble chemicals can pass through the skin. Has 20 sf surface area.

30 30 Routes of Exposure Ingestion – can occur through food contamination, eating drinking in lab, poor hygiene, mucociliary transport of vapors trapped in upper air ways, Injection – Can occur through injury and needle sticks

31 HMIS Label - Example Secondary Labeling System CARCINOGEN

32 Labels- Symbols and Pictures

33 Labels - Example

34 Safety Data Sheets (SDS ’ s) Chemical document put out by manufacturer detailing physical and health hazards One for every hazardous chemical on campus Master file located in EHS Dept. Review before working with any chemical

35 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.

36 Information on SDS’s Control measures Physical hazards Routes of entry into body Acute and chronic health effects Carcinogenicity Handling and storage precautions

37 Chemical Sensitivities Many hazardous chemicals are used in the workplace Immune responses can vary among individuals Low-dose exposures over longer periods of time can alter function of immune system

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

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

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

41 Protective Measures Prevent Ingestion NO eating, drinking, smoking, or applying cosmetics in labs Wash hands frequently Label everything Read labels and SDS’s Wear your lab coat Don’t work alone

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

43 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

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

45 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

46 Emergency Procedures Chemical Spills (Appendix A – CHP) Evacuate and call Police at 911 for larger spill (>5-gallons) situations Treat life threatening injuries immediately Contain the spill - read SDS Wear protective equipment during clean-up Best response is preparation

47 Emergency Procedures Personal Contamination Flush contaminated area with water Remove contaminated clothing Rinse with water for 15 minutes Seek medical attention if irritation persists

48 Emergency Procedures Chemical in the Eye(s) Flush eyeballs and inner eyelids Forcibly hold eyes open Irrigate for at least 15 minutes Seek medical attention immediately

49 Industrial research labs  Industrial labs are nice and neat  There is quite a bit of chemistry going on there  Companies live and breath lab safety  Companies won’t fire employees if their science fails, but the employees who don’t work safely will be fired  Companies are beginning to ask questions about safety in interviews

50 Power cords and electrical wiring. Easily damaged, invisible damage.

51 Summary You may be exposed to hazardous chemicals or chemicals products used on campus Information is available on labels and SDS’s Program is in place in your work area to inform and train you
