PROTECTIVE CLOTHING THAT MUST BE USED FOR ALL WORK:

• Safety Glasses - Must be worn when flying debris is expected (such as power tools); Safety goggles also encouraged when soldering or working with chemicals.
• Face Shields /Dust Masks– Cover mouth when sanding piezoelectric material (PZT) to avoid inhalation.
• Gloves - Latex gloves for standard work with "mild" chemicals; insulated gloves for work with cryogens. For other specific glove type vs. chemical, see http://www-safety.deas.harvard.edu under "Safety Committee Services."

GENERAL HOUSEKEEPING RULES:

Keep clean and free of clutter. Put tools and chemical bottles away when finished

WASTE DISPOSAL RULES:

1. Everyone needs to take the training offered by EH&S pertaining to the disposal of hazardous waste.
2. The satellite accumulation area is located next to sink in back room.
3. Dispose of flammables (acetone and alcohols) in separate waste container from corrosives (sodium hydroxide)

FUME HOOD USE:

Cleaning agents (acetone, alcohol) are used in lab, where we have no fume hood. Anything stronger (tip preparation, sample-growing, and cleaning with HF) should be taken to the fumehood in G16a, when no lab classes present.

CHEMICAL STORAGE:

1. Large bottles of liquid are stored in secondary containment trays under sink. Don’t buy more than one extra bottle at a time. Small (squirt) bottles are on shelf above sink.
2. Fridge in front room is for food. Fridge in back room is for chemicals ONLY.

SPECIAL TRAINING REQUIRED:

1. All lab personnel who work with chemicals must take training in the use and disposal of chemicals.
2. In addition, training is available in laser safety, machine shop safety, and safety when using compressed gases.

CHEMICAL SPILL CLEANUP PROCEDURES:

1. Small spills should be cleaned up by those in the lab. The nearest spill kit is in Pierce B-4 (Carl Gottlieb, 5-9848)
2. For large spills, clear the area of personnel and call the University Operations Center (5-5560).

OTHER RELEVANT COMMENTS:

1. To climb into pit, first secure ladder in notch between scaffolding and platform.
2. Make sure metal “lids” of pit are securely in place, not crooked; always get buddy to help you move them. Keep floor of soundroom clear to avoid tripping hazards.
3. When sanding PZT, or in any other way generating small amounts of toxic dust, wear gloves and face mask, contain dust on paper towel, clean area thoroughly afterward and wash hands.
