Micro/Nano Technology Center Orientation and Safety TrainingUniversity of Louisville

This Orientation

• Is meant to be an introduction to the manual• Is going to teach you basic rules and regulations,

preventative safety measures, and how to respond to safety incidences.

• Will show you where to get more information about topics covered in this presentation

The Manual

• Has information about general procedures, rules for working in the cleanroom and safety procedures in the cleanroom.

• Should answer most of your questions. If you can’t find something or have a question let us know!

Responsibilities

• If you fail to follow these rules, consequences will happen – including the potential loss of cleanroom access.

GENERAL RULES AND REGULATIONS

Cleanroom Access To enter the cleanroom you need to complete:

General Lab Safety Training (DEHS)Hazardous Waste Safety Training (DEHS)Cleanroom Access Training followed by a Safety Quiz you

gowning room and fill out log on wall. Make sure to note any contamination.

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 Apron 2. Tie Apron 3. 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 RoomThe Loading DockThe Back CorridorOnline

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 beakersConstantly 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• 502-589-8222 – Poison Control

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!

Hydrofluoric Acid (HF) HF is a very dangerous chemical. If contact occurs:

Immediately rinse affected skin with water.Remove all jewelry or clothing exposed to HF.Have a buddy CALL 911.After washing for 5 minutes, do not dry the skin.Cover entire affected area with calcium gluconate gel

(Calgonate).Continuously apply fresh gel while on the way to the ER

and while waiting.

HF in Eyes

• Have a buddy call 911 and request an ambulance• Flush eyes at eyewash station for 5 minutes• After 5 minutes, switch to calcium gluconate (Calgonate)

eyewash• Continue flushing until told to stop in ER• Get MSDS

Chemical Spills Simple Spill:

Does not spread rapidlyIs not toxicDoes not endanger people

or property (except by direct contact)

Does not endanger environment outside of building

Less than ½ a gallon of liquid

Large SpillSpreads rapidlyToxicEndangers people or

propertyEndangers outside

environmentMore than ½ a gallon of

liquidAny amount of HF

Simple Spill

• Check self for contamination.• Check bench and floor for contamination.• Label the spill.• Contact cleanroom staff for supervision of cleanup.

Large Spill

• Check self for contamination.• Push HAZMAT alarm.• Evacuate the cleanroom.• Call 911.
