Laboratory Safety Training Quiz

The questions for this quiz may be from the power point presentation, videos or the Chemical Hygiene Manual. This is an open book quiz, however you must have a passing grade of 80% to have completed this section even though 100% should be attempted. Also, feel free to discuss the questions and answers with other OSU-CHS personnel who work in laboratories. The purpose of completing the quiz at 100% is to demonstrate that you have studied the information, understand the principles, and have gained the knowledge to work safely in the laboratory environment. What you learn may prolong your life and those of your co-workers. To complete the quiz choose the best answer of the multiple choices.

Choose the best answer for each question below. When all questions have been answered, click "Submit Quiz."

  1. When you are arranging your chemical storage, you should:
    Store the chemicals in alphabetical order to make it easier to find the chemicals when you need them; after all it takes too much time to check out the MSDS to see if chemicals stored near each other are incompatible
    Store flammable chemicals in any cabinet as long as they are in amber glass containers to reduce light
    Store highly toxic chemicals in cabinets that must be lockable to prevent theft and/or possible inadvertent exposure
    It is okay to store chemicals on the floor next to the counters and cabinets when the laboratory is too crowded to place with other chemicals
  2. You should always label your waste container because:
    "Unknowns" cannot be shipped for disposal without a costly identification test
    Labeled waste containers are required by EPA/OSHA
    The Lab Safety Coordinator will know how to categorize it
    All of the above
  3. The chemical concentration in air is considered safe for most people when:
    You and your coworkers cannot smell it
    It is below the PEL
    You are not having any adverse health affects
    It is above the PEL
  4. What should you do first if there is a minor hazardous chemical spill in your work area:
    Run out of the building
    Inform your supervisor and coworkers
    Contact the custodian to clean the area
    Call 911
  5. A chemical container's label is becoming unreadable although you can make out the name; you should:
    Plan on disposing the chemical
    Replace the chemical name before it too becomes completely unreadable
    Ensure a new label is added with a minimum of the name of the chemical, the manufacturer's name, phone number and associated hazards
    Replace the chemical name and the hazards
  6. A person is about to use a chemical they have never used or have used very infrequently, what should they do:
    Read the MSDS and other informative information
    Determine how it will react with other chemicals it will be used with
    Determine what personal protective equipment they should wear
    all of the above
  7. A chemical that may be explosive can be used if:
    The chemical hygiene and radioisotope use committee and the research office have given approval
    The MSDS and other informative information has been read and possible hazards have been mitigated
    Less than 10ml will be used and it will be used in a fume hood
    The PI has performed a risk assessment and decided that it can be used safely
  8. A person has completed their work in a fume hood and has 5 ml of isopropyl alcohol remaining in a 100 ml beaker; the person should:
    Pour the 5 ml left down the hood sink.
    Close the hood sash and leave it in the open beaker in the hood to evaporate
    Pour the remainder into the original container and close the lid
    Pour the remainder into the solvent waste container
  9. What should a worker do prior to working alone during off-hours (before 7 a.m. and after 5 p.m.):
    Plan normal prudent practices while working in the laboratory because the worker is not working with hazardous materials
    Assess equipment and chemicals/materials that will be worked with for hazardous materials designation: possible potential for causing personal injury requiring an emergency response
    Establish a surveillance procedure that includes checking with someone at predetermined times
    all of the above
  10. What effects may be related to the reproductive or developmental toxin aspects of a chemical:
    Sterility
    Carcinogenicity
    Neurotoxic effects
    Dissolving of human tissue
  11. If you catch on fire you should:
    Yell, run and find someone to help you
    Lay on floor and roll to smother fire
    Pull the fire alarm and wait for help
    Pat fire with hands to extinguish it
  12. What effects may be related to exposure to corrosives:
    Neurotoxic effects
    Dissolving of human tissue
    Narcosis
    Sterility
  13. The person ultimately responsible for your safety training in each laboratory is:
    The principal investigator and yourself
    The designated lab assistant
    The chemical hygiene and radioisotope use committee
    The Lab Safety Coordinator
  14. If you see something in the lab that is hazardous or dangerous, tell the supervisor/PI (for students) or remediate (for PI, technicians).
    When you have time
    At once
    When current work activity is complete
    None of above
  15. To conduct a work project safely you should:
    Read applicable scientific literature and hazard assessments
    Understand each step of the procedures thoroughly before beginning the project and during the project
    Know the physical and toxicological properties of the chemicals you are working with
    All of the above
  16. If the building alarm goes off, you must:
    Exit the building as soon as possible in an orderly manner
    Run outside as fast as possible
    Ask your supervisor for directions
    All of the above
  17. Describe the procedure for smelling a chemical:
    Stick your nose close to the vessel and breath deeply
    Point vessel away from face while gently fanning vapors toward nose
    Never smell a chemical
    Smell chemical as you would anything else
  18. If you spill a small amount of a nonhazardous solid on the lab bench, you should:
    Notify the PI
    Clean the bench at end of the work activity
    Leave it there
    Clean it immediately
  19. The effect a certain chemical has on the body depends on:
    The physical form of the chemical
    How the chemical enters the body
    Amount that enters the body - the dose
    All of the above
  20. What is the most effective practice in using protective gloves:
    Selecting the best glove type
    Changing gloves when contaminated
    "Double gloving"
    Washing hands often
