3. In addition, training is available in laser safety, machine shop safety, and safety when using compressed gases.

CHEMICAL SPILL CLEAN-UP PROCEDURES:

1. Small spills should be cleaned up by those in the lab.
2. The location of our spill kit is in the main calibration lab.

OTHER RELEVANT COMMENTS:

1. When a laser warning light is activated, do not enter that area unless you're told by the laser operator that egress can be done safely.
2. Always "ask first" before attempting to take any action that might be hazardous.
