4. Non-PPE Controls

5. Hierarchy of Controls

   More than PPE
6. Eliminate/Minimize Hazards *Using PPE as a primary hazard control is a poor safety practice. http://www.jst.umn.edu/SOP%20resources.html
7. How to Eliminate/Minimize Hazards How can you eliminate or minimize the identified risks? Standard methods include: 1. Substitution - Use a less hazardous reagent in place of a hazardous one 2. Administrative Control - Modify your procedure or reaction scheme to minimize the risk the hazardous step 3. Personal Protective Equipment*– Use appropriate PPE *A last resort when other methods fail. Using PPE as a primary hazard control is considered a poor safety practice. http://science.widener.edu/svb/olcc_safety/papers/benedict.pdf

22. Gloves: The basics

    Best practices for wearing disposable gloves
23. Gloves Select gloves made of material known to be resistant to permeation by the substances in use. Lab Safety Supply Company provides chemical compatibility guide for gloves at http://www.labsafety.com/refinfo/ezfacts/EZ166.pdf. Check gloves (even new ones) tears or pinholes. Select gloves of the correct size and fit Too small  uncomfortable and may tear Too large  low dexterity Remove rings and jewelry that can tear gloves UofM, Department of Environmental Health and Safety. Bio Basics Fact Sheet: Glove Selection and Use http://www.dehs.umn.edu/PDFs/gloves.pdf
24. Gloves Replace gloves when Contaminated Permeated by solvent Torn You have been wearing them awhile Some gloves, especially lightweight disposables, may be flammable Keep hands well away from flames or other high temperature heat sources Consider double gloving, if working with A highly hazardous compound Radioactive materials Situations were there is a high potential for spills or splashes UofM, Department of Environmental Health and Safety. Bio Basics Fact Sheet: Glove Selection and Use http://www.dehs.umn.edu/PDFs/gloves.pdf
25. Gloves Remove gloves before leaving lab area. Remove in a way that avoids skin contact contaminated glove exterior Dispose of gloves in non-hazardous (normal) trash If radioactive chemicals were used, place in radioactive waste. www.hsc.wvu.edu/safety/Laboratory-Safety/Personal-protective-Equipment/Hand-Protection Wash hands Do not attempt to re-use disposable gloves. Increased risk for contamination UofM, Department of Environmental Health and Safety. Bio Basics Fact Sheet: Glove Selection and Use http://www.dehs.umn.edu/PDFs/gloves.pdf
26. Gloves To prevent the unintentional spread of hazardous substances, when wearing gloves don’t touch Anything used outside the lab Doorknobs, personal telephones, pens, etc. Your face or clothes If you are transporting a chemical in the hallway, only wear a glove on one hand. Have a policy (gloves or no gloves) for lab computer use. Post your policy on the computer to remind visiting researchers. UofM, Department of Environmental Health and Safety. Bio Basics Fact Sheet: Glove Selection and Use http://www.dehs.umn.edu/PDFs/gloves.pdf

27. Gloves: Chemical Compatibility

28. Glove Comparison Chart Incidental contact:little or no direct contact with the hazardous material. Extended contact: handlinghighly contaminated materials; submerging hands in a chemical or other hazardous substance; need for physical protection from temperature extremes or sharp/piercing objects http://www.ehs.berkeley.edu/hs/63-laboratory-safety/94-glove-selection-and-usage.html
29. Water based solution, organic solvents, acids and bases, halogenated hydrocarbons
30. Glove Usage Wear gloves of a material known to be resistant to permeation by the substances in use. Look for an expiration date on individual packages of gloves. Before use, check gloves (even new ones) for physical damage such as tears or pinholes. Check reusable gloves for previous chemical damage. Dispose of gloves when they show any sign of leakage or deterioration. Select gloves of the correct size and fitting. Some gloves, especially lightweight disposables, may be flammable: keep hands well away from flames or other high temperature heat sources. Replace gloves periodically, depending on the frequency of use and their permeation and degradation characteristics relative to the substances handled. Remove gloves before handling objects such as doorknobs, telephones, pens, and computer keyboards. When removing gloves, do so in a way that avoids skin contact with a possibly contaminated glove exterior. Always wash hands after removing gloves. Dispose of contaminated gloves properly. Do not attempt to re-use disposable gloves. http://www.dehs.umn.edu/PDFs/gloves.pdf
31. Handling the Heat OSHA (U.S. Department of Labor Occupational Safety & Health Administration) Select gloves that provide guarding and insulation Heat resistant gloves (attention: never wet the gloves when you put the autoclaves in water;water is a heat conductor)
32. Prevention and protection Read SDS and learn about the temperatures, then select appropriate PPE and employ additional controls Diethyl ether

45. Flame Resistant Sleeves

    A great alternative to a flame resistant lab coat
46. Flame Resistant Sleeves $11.00 per pair vs. ~$100 for a full lab coat Fits over normal lab coat sleeve Protects part of arm most likely to come in contact with flammables while working in the hood http://workingperson.com/national-safety-apparel-16-9oz-fr-green-sateen-sleeve-sewn-in-elastic-s02grrg02.html#details
47. Sleeves Cover your arms Make sure sleeves don’t inhibit work Be conscious of longer street clothes sleeves that stick out of a lab coat http://www.sigmaaldrich.com/labware/safety.html http://onqor.net/ordering/index.php?route=product/product&product_id=57

48. Respiratory Protection

    Is a respirator needed? How can you get one?
49. Respiratory hazards Aerosolization during common lab procedures – e.g., weighing solids for making solutions – Tris, SDS, Ascorbic acid, MES hydrate. Harmful/irritating to the eyes and lungs. PPE Gloves, goggles, lab coat. In general read MSDS before using any chemicals, and possibly respiratory mask. Upon exposure Eyes : Rinse at the eye shower Inhalation: Move to fresh air, seek medical aid if experiencing discomfort
50. Respiratory Protection Program Check the MSDS to determine if a respirator is needed for the chemicals you are working with. If use of a respirator is required, DEHS will provide you with information to enroll in the University’s Respiratory Protection Program through the Office of Occupational Health Information on the Respiratory Protection Program can be found at: http://www.ohs.umn.edu/rpp/home.html Minimum requirements for the program include filling out a health survey and a fit test for the type of respirator you will be using Additional information is available through the website http://www.ohs.umn.edu/prod/groups/ahc/@pub/@ahc/@ohs/documents/asset/ahc_asset_108552.pdf

51. Thermoluminiscentdosimeters for working with radiation

    See the safety moment in the chemical category

52. PPE Protocol

53. Personal Protective Equipment

    Where – and where not – to wear it!
54. Wear PPE when: When using a “gloves on” keyboard Wear gloves when using this keyboard. Lab coat is okay to wear when walking from lab to lab, unless is it known to be contaminated with a particularly hazardous substance. Working in laboratory spaces
55. When NOT to wear PPE Bathrooms When using a “gloves off” keyboard When using mobile phones Offices/ non-lab spaces Outside
56. When NOT to wear PPE When quenching your thirst. Don’t risk ingesting chemicals and spreading them to drink containers. Is a beverage container only touched with gloves on? Note: Labs where hazardous chemicals are used have 6 - 12 air changes per hour.  Increased thirst
57. Transporting Chemicals Use secondary containment (bucket) One gloved hand, one ungloved hand Carry other needed PPE if moving between labs

58. PPE and Chemical Packages

59. Opening Chemical Packages PPE required to transport chemicals within and between labs Best practice suggests PPE should be worn when opening packages containing chemicals Packaging is form of engineering control PPE protects in case that control fails

60. Lab Coat Laundering System

61. Importance of a Clean Lab Coat Wearing a seriously soiled lab coat is like wearing hazardous waste! Chemistry department now offers a FREE lab coat laundering service Monthly service
62. How it works Every 4th Wednesday Drop off dirty lab coats to Smith S18 Make sure your name is written on the pocket (not collar) There will be two hampers: Coats that DO have the vendor’s barcode in the collar Coats that DO NOT have the vendor’s barcode in the collar. Look for a monthly email reminder Thursday afternoon, 4 weeks later Pick up your clean lab coat from Smith S18
