Gas Cylinders

• Gas cylinders must be changed by designated, trained staff personnel.

• DO NOT attempt to change a gas cylinder.– Contact staff before weekend run to verify gas level.

• NO hazardous process gas will be placed in a laboratory

Laboratory OrientationGas and Chemical Delivery Procedures

Gloves are for your protection and the protection of the equipment or process

• Gloves may not be used to:– Open doors– Answer Phones

Laboratory OrientationGloves

• Laser Laboratories– The foremost concern is the danger to one’s eyes and

exposed skin. The user must be trained and certified on working the laser and wear the appropriate eyewear protection.

– Contact REM for laser safety training.• Biology Laboratories

– For biological hazards, special training is necessary.– Contact REM for biological safety training.

• X-Ray sources– Contact REM for X-ray safety training

Special Hazards

Policies

• No food or drinks in labs, galley or subfab.• No Smoking anywhere in the building.• PPE requirements are for all times

Citizenship Violations - Equipment• The Birck disciplinary committee is comprised of two faculty

members, a staff scientist, a student representative, and the engineering manager. Policy and safety violations are first discussed between the engineering manager and the violator(s), after which the level of discipline is recommended to the committee, who determines the final disposition of the issue. The committee can decide penalties from restricted access to suspension, depending on severity.

• All users are responsible for cleaning up after themselves and for leaving their work areas ready for use by others.

• If any user is observed leaving a mess in a hood or near equipment, or leaving an unattended tote not in its proper storage location, they will be subjected to mandatory participation in 4 hours of weekly staff support duties, or a one-week suspension of all cleanroom privileges. This means denied access to the cleanroom for one week.

• engineering– local exhaust ventilation– remote handling of materials

• administrative– limit work time – rotate work groups– break areas separate from work areas– no smoking, eating, drinking, or applying

cosmetics in work area

Effectiveness of PPE

RTK TRAINING• LOCAL

– Involves one site in the body, usually the point of contact

• Skin irritation or burns• Eye irritation or burns• Upper respiratory tract irritation

• SYSTEMIC– Involves more than one part of the body,

not just the point of contact• Central nervous system:

– headaches, dizziness, nausea, etc.• Organ damage: liver, lungs, etc.• Cancer

General Glove Use • General use – Nitrile (Blue-Microflex)

• Single glove (on the non-dominant hand) use for control of contamination to samples/ devices outside the lab

• Biological Safety Level 1 (use of Gray Gloves)• Not to worn outside the lab

• Biological Safety Level 2 (use of BlackGloves)• Not to be worn outside the lab!

Fume HoodsAll fume hoods are labeled as

“Acid” (Acid/Base/Aqueous) or “Solvent” hoods

• The separation of hood types is for chemical compatibility.• Users should ensure they are following all Personal Protective

Equipment requirements for the hood type being used.

General Hood Designation:Acid Hood or Solvent Hood• Acid Hoods (Inorganic Chemistry)

• PPE Requirements – Nitrile gloves, Orange Acid Gloves, Chemical Smock, Safety Goggles and Face-shield

• + + + +

• Solvent Hoods (Organic Chemistry)• PPE Requirements – Nitrile Gloves, Solvent

Gloves, Lab Coat, Safety GogglesO + + +

Minimum PPE

Acid Hood - Waste Disposal• Birck Nanotechnology Center has an active

acid/base neutralization system. • This allows the disposal of acids and bases

via the hood drain. • Please make sure materials are poured

slowly and with a lot of water for dilution.• High heavy metal containing wastes (ex.

spent plating baths) need to be containerized and sent as hazardous waste.

Solvent Hood – Waste Disposal• Only water is to be disposed of down

a solvent hood drain. • Solvent waste is place in one of two

containers, depending on whether a chemical in the solution contains a halogen (Fluorine, Chlorine, Bromine, Iodine)• Non-halogenated in one container.• Halogenated in the other.

• Replace container cap immediately upon completion of adding waste to containers

Empty Container DisposalO Proper disposal of empty containers:

• Container has been triple rinsed and semi-dried using a nitrogen gun.

• Cap has been rinsed, dried, and thrown in trash can.

Cap has been removed and disposed of.

Disposal label has been applied.

HF and BOE Hazards• Hydrofluoric Acid and Buffered Oxide Etch

• Potentially highly corrosive and highly systemically toxic

• Treatment – Decontamination followed by application of 0.13% Benzylkonium Chloride

• Additional treatment 2.5% Calcium Gluconate

HF and BOE Hazards (Continued)

• If skin contamination occurs:• surface pain will occur• unlike other acids, once

rinsed, deep tissue pain will follow.

• Treatment as soon as possible with 0.13% Benzalkonium Chloride –follow procedure from HF first Aid kit. Then dial 911.

TMAH Hazards• Tetramethylammonium Hydroxide (TMAH)

• Potentially highly corrosive and highly systemically toxic, esp. at 25% concentration

• 2.4% TMAH is basis for metal ion free photoresist developers: MF CD-26(A), MF-319, AZ 326/726/826, etc.

• Tetramethylammonium (TMA) ion is neurotoxic; Strongly basic/caustic solution liquefies skin and allows TMA ion to be rapidly absorbed through skin.

• In case of skin contact: Take off contaminated clothing and shoes immediately. Wash off with plenty of water. Take victim immediately to hospital. Consult a physician.

• In case of eye contact: Rinse thoroughly with plenty of water for at least 15 minutes and consult a physician. Continue rinsing eyes during transport to hospital.

Spill Carts and Emergency Procedures

• Spill Carts located in galleys• Designed for spills less than 1 gallon

For spills greater than 1 gallon – Need staff assistance (63333)
