PREVENTATIVE SAFETY TRAINING

Emergency Equipment and Locations in the Cleanroom Section 10 of the manual (page 17) lists important safety equipment that you will need to be familiar with. This equipment will be referenced throughout the rest of the presentation and you will be required to label most of it on your quiz.

Personal Protective Equipment  For personal protection against chemical spills.  These are chemical resistant – not chemical proof.  Always wear when working with chemicals.  Always inspect Personal Protective Equipment before and after use. Check for holes, stains and other indicators of contamination.  Do not wear PPE outside of the wet bay.  Complete directions in Section 11 of manual (page 21)

How to Wear Personal Protective Equipment 1. Inspect Apron2. Tie Apron3. Use 10% IPA in Water on towel to clean Face Shield 4. Put on Face Shield 5. Adjust Face Shield 6. Put on Chemical Resistant Gloves over apron sleeves OR 7. Double Glove with Nitrile Gloves.

How to Wear Personal Protective Equipment 1. Check gloves, apron and face shield for contamination. If not easily cleaned, throw away. 2. Wash gloves 3. Dry Gloves using a towel 4. Remove and Hang Face Shield 5. Remove and Hang Apron

Material Safety Data Sheets  Also known as MSDS’s.  You must thoroughly review a chemical’s MSDS before using that chemical.  Copies of MSDS’s for all chemicals can be found in: The Gowning Room The Loading Dock The Back Corridor Online

Rules for Working with Chemicals (pages 28-29)  You must read the MSDS before working with a chemical.  Know if the chemicals you use must be used in glass or plastic beakers.  Always wear appropriate protective equipment.  Never wear PPE outside of the wet bench area.  Always stand when working at wet benches.  Only work with chemicals in their designated areas.

Rules for Working with Chemicals  Assume any liquid is potentially dangerous.  Only use dedicated tanks/baths as they are designated.  Uncap only one bottle at a time. Pour chemicals slowly.  Keep gloves dry and clean.  When using hot plates: Only heat Pyrex beakers Constantly monitor temperature

Rules for Working with Chemicals When mixing chemicals: Pour acids into water. Do not mix acids and solvents. Do not mix halogenated solvents with non- halogenated solvents. Label all mixtures. Do not leave chemicals unattended. Do not pour chemicals back into storage bottle.

Rules for Working with Chemicals Always put the cap back on securely. Define new bottles, including Hazardous Waste bottles. Clean up your work area. Place empty bottles on the bottom shelf of the chemical cabinet it came from. Make sure all PPE is clean and dry before returning it to storage areas.

RESPONDING TO SAFETY INCIDENTS

Responding to Safety Incidents The following slides detail basic steps to follow in case of emergency An emergency poster is placed in the gowning room for quick reference. Two important phone numbers: 911 – Emergency Services – Poison Control

Fire Alarm  You Hear: The Fire Alarm  You See: Flashing White Lights  You DO: Evacuate the Building Immediately – Meet in Lutz Hall Lobby  Warn others as you exit  Do not attempt to de-gown  Do not try to finish an experiment or figure out why an alarm is sounding

HAZMAT Alarm  You Hear: The HAZMAT Alarm  You See: Flashing Blue Lights  You DO: Evacuate the Building Immediately – Meet in Lutz Hall Lobby  Warn others as you exit  Do not attempt to de-gown  Do not try to finish an experiment or figure out why the alarm is sounding

Carbon Dioxide Alarm  You Hear: The Carbon Dioxide Alarm  You See: Flashing White Lights from 1 or more benches  You DO: Evacuate Building Immediately – Meet in Lutz Hall Lobby  Warn others as you exit  Do not attempt to de-gown  Do not try to finish an experiment or figure out why the alarm is sounding.

Fire and HAZMAT Alarm  You Hear: The Fire Alarm AND the HAZMAT Alarm  You See: Flashing White and Blue Lights  You DO: Evacuate the Building Immediately – Meet in Lutz Hall Lobby  Warn others as you exit  Do not attempt to de-gown  Do not try to finish an experiment or figure out why the alarm is sounding

Minor Chemical Spill on a Person  Minor chemical spills are not life threatening, are not a health hazard and do not pose long-term health risks or risks of disfigurement.  Call Poison Control and Staff.  Place affected skin under running water for 15 minutes.  Remove any contaminated clothes or jewelry.  If ER trip is needed, call 911 and bring MSDS with you.

Major Chemical Spill on a Person  Major spills are immediately life threatening, a health hazard or pose long-term health risks or risk of disfigurement.  Call 911 and demand an ambulance.  Get under a running safety shower.  Remove all contaminated garments and jewelry.  Bring MSDS with you to the ER.

Flammable Solids on Skin Brush off as much as possible. Treat as small spill on skin. Check the MSDS before using any chemical – some flammable solids react with water!

Chemical Splash in Eyes Have a buddy call 911. If you are wearing contacts – take them out! Flush eyes in eyewash fountain for 15 minutes. Go to ER and bring MSDS.

Safety Buddies If you see someone who is in distress, you automatically become their safety buddy. Call 911. Be sure you are wearing proper protective apparel before helping the victim. Take MSDS to the ER.

First Aid for Other (Minor) Incidents  Chemical Inhalation Check area for safety. Close open containers. Move victim to safety. Call 911. Resuscitate with rescue breathing if necessary.  Chemical Ingestion Go to ER or call Poison Control.
