 | What ever you do, use your common sense! |
| There might be invisible laser radiation present in this laboratory. Don't
have your eyes level with the table. If you have to pick something up from
the floor, close your eyes when passing the table level. |
| Don't look directly into the laser or stare at beam reflecting from any
surface. |
| Block the laser beam while you are not using it. |
| In case the laser isn't working talk to your TA. Don't try to fix it
yourself, some lasers contain lethal voltages and other are easily damaged
and very expensive to replace. |
