Chemical Safety Regulations for Workshops and Demonstrations

placeholdertwoRight1

Safety Training at the BCCE

Workshop Leaders and Chemical Demonstrators will be required to attend a short Chemical Safety, Disposal of Chemicals, & Information about ND Safety Rules and Regulations prior to their workshop or presentation. These sessions are scheduled for 5 pm on either 28 July or 29 July 2018 - You must attend one of these two sessions. Please arrange your travel so that you will be able to attend one of these sessions before the beginning of your workshop or demonstration. If you do not attend one of these meetings, you will not be allowed to give your presentation or use chemicals in your workshop -- this is a non-negotiable requirement -- nor will you receive reimbursement for workshop expenses.


 

Minimum Safety Guidelines for Chemical Demonstrations
ACS Division of Chemical Education

Physical and chemical demonstrations in the classroom or in a public venue can have both educational and motivational value and are a long‐standing pedagogy in chemical education. All individuals who are planning chemical demonstrations have an ethical and legal responsibility to follow and document safe laboratory practices for each demonstration. These guidelines have been created based on current best practices and provide a checklist of key issues for demonstrators to assure that chemical demonstrations are conducted safely and without incident. Because no such list can address all possible uses and hazards of chemicals in this application, these guidelines are intended for use by persons who have appropriate education and experience in chemistry and chemical safety.

Before the Demonstration

1. Always follow a tested, written procedure that includes comprehensive safety precautions. Plan the demonstration at the smallest scale possible for the location and viewers.

2.. Review the safety precautions which will help you identify the potential hazards involved in the demonstration and understand the risks due to exposure and/or improper handling of a chemical, process, or procedure. Effective safety precautions provide easy‐to‐follow instructions to minimize risk and prevent unplanned incidents that could result in injury or property damage.

3. If a written procedure is not available, or safety precautions are not clear, perform an independent hazard and risk assessment to identify the possible hazards and evaluate the risks. In the risk assessment, consider the pedagogical value compared to the risk. Write the demonstration procedure with appropriate safety precautions to protect against the hazards and reduce risk. Refer to these guidelines as you write the demonstration procedure, and retain the procedure on file for future use.

4. Always practice a demonstration before presenting it before students or an audience for the first time.

5. Ensure that all demonstrations are appropriate for the room being used and the available safety equipment. Keep all exit paths clear. Check the ventilation in the demonstration area to ensure that participants and audience members will not be exposed to harmful quantities of toxic gases or chemical vapors. The use of a fume hood is required for any demonstration that uses or produces a substance with a TLV less than 50 ppm (check the SDS for the TLVs of all chemicals).

6. Consult current Safety Data Sheets (SDS) and review the safe handling information for all chemicals used in the demonstration.

7. Prepare and follow a safety checklist for all combustion demonstrations involving the use of a flammable liquid. Dispense only the amount of the liquid required BEFORE beginning the demonstration. Cap the solvent bottle and REMOVE it from the demonstration area before applying the ignition source. NEVER add more flammable liquid to a combustion demonstration once it is underway.

8. Ensure that observers will be a safe distance (10 feet or more) or are protected by a physical barrier, such as a polycarbonate shield, from the demonstration area when working with flammable, corrosive or toxic substances. In a small setting such as a classroom or lab, all participants and observers must wear appropriate eye protection at all times.

9. Ensure there is an appropriate fire extinguisher on hand whenever the slightest possibility of fire exists and that you have the knowledge, experience and training to use it properly in the event of an emergency.

10. Keep a spill kit nearby to contain, absorb, and neutralize any spilled chemicals.

11. Plan for appropriate handling or disposal of reaction byproducts or excess chemicals in accordance with institutional policies.

During the Demonstration

12. Wear appropriate personal protective equipment (PPE) for the level of risk as determined by the assessment, such as chemical splash goggles, chemical‐resistant gloves, and a lab coat, to protect against the hazards. Active participants must also wear appropriate PPE.

13. Provide safety shield protection whenever there is the slightest possibility that a container, its fragments or the contents could be propelled with sufficient force to cause exposure and/or personal injury.

14. Warn members of the audience to cover their ears if a loud noise is anticipated.

15. Participants and spectators must not taste any food or non‐food substances used in the demonstration.

16. Do not perform demonstrations in which parts of the human body will be placed in danger (such as placing dry ice in the mouth or dipping hands into a hazardous liquid).

Special Notes for Outreach or Public Demonstrations

17. Ensure proper packaging and secondary containment for the safe transport of all chemicals to and from off‐site locations. Materials of Trade (MOT) exceptions to Department of Transportation requirements allow for the transport of certain hazardous materials without a license or shipping papers provided certain guidelines are met. There are strict limits on the amounts of material, depending on the hazard. Visit the links below for more information about hazard classes, packaging requirements, and restrictions on the amounts of chemicals.

http://www.acs.org/content/dam/acsorg/about/governance/committees/chemicalsafety/safety practices/transporting‐chemicals.pdf

18. Notify security and/or administrators that you will be performing demonstrations. If public space will be used for demonstrations involving fire, contact the local fire department to determine if the demonstrations meet local fire and building use codes.

19. Provide a written demonstration procedure, including comprehensive safety precautions and risk assessments, whenever the audience will be encouraged to conduct the demonstration at another time.

HOW CHEMICALS WILL BE DEALT WITH at the 25th BCCE

The University of Notre Dame Guidelines for transportation, storage, preparation, presentation , and disposal of chemicals at BCCE

Transportation : Owing to the increased security that characterizes transportation systems within the U.S., the 25th BCCE recommends that participants DO NOT carry chemicals with them or in their luggage while traveling on airlines. All hazardous chemicals shipped to or from ND must be shipped in accordance with US Department of Transportation packaging and shipping regulations.

Storage of chemicals : Storage of chemicals in automobiles parked on the ND campus or in ND residence halls will not be permitted. Participants who bring chemicals with them must make prior arrangements with DeeAnne Goodenough, Safety Chair, for proper storage of the chemicals within Jordan Hall of Science. There will be a secure room for you to store your prepared chemicals.

Preparation and Presentation : Individuals preparing, presenting, or involved in the clean-up of chemical demonstrations at the BCCE must be registered participants of the BCCE. Individuals involved with preparing, presenting, or cleaning-up of chemical demonstrations at the BCCE must wear appropriate safety equipment (safety goggles, gloves, lab coat, etc.). Individuals should bring their own personal protection equipment . You are responsible for the preparation and presentation of your chemistry workshop (within the workshop room). Do not expect the BCCE committee or the ND Department of Chemistry and Biochemistry staff or students to prep your workshop. We will provide proper transportation of the chemical materials to the room where the presentation will occur.

Minimum PPE for laboratory work at ND: Any individual working in a laboratory in the Chemistry and Biochemistry Department at ND is required to wear long pants to cover the ankles, t-shirt or equivalent coverage, closed toe/heel shoes with adequate soles, and appropriate eye protection in addition to an appropriate laboratory coat (standard or FR depending upon the nature of the work being done). We will have a limited number of laboratory coats for use in the preparation and demonstration facilities.

Disposal : Owing to the increase in cost of disposing of waste generated by chemical activities and demonstrations, the Department of Chemistry at ND reserves the right to say no to the use of certain chemicals . Only neutral salts or neutralized acid - base reactions that have a measured pH between 6.0 and 8.0 can be disposed of in an expedient manner. If you generate chemical waste in a ND laboratory or classroom, you must cooperate with us in following ND's procedures for the proper disposal of your waste. The University of Notre Dame demands waste generated by your workshop to be placed in appropriately labeled waste containers. Waste containers will be provided. The Department of Chemistry staff will deal with waste disposal. Chemical waste is NOT transported between buildings by individuals. The ND Chemical Safety Chair , DeeAnne Goodenough, will designate a room as a waste disposal area. If you have unused chemical reagents, you cannot leave these chemicals in our department without written permission to do so. Our department must track the identity and quantity of all chemicals that enter the building from time of entry to use and disposal.
