Open and rusted razor blades in the old lab by the sink.  This is
a potential hazard.  Suggestion: To not use the razors for scratching
bottle labels, but use a tool such as a can opener; this tool would be
hung next to the sink or bottle disposal trash can.  Also, after using 
one of the razor blades, dispose of it properly.  Good health to you!

Robert Norman has come up with a good safety suggestion and
he will add it to the bottle disposal area in the old lab.
He'll make a bottle scratcher to replace the razors and put
it on some ball chain to keep it from walking.

Robert Norman has come up with a good safety recommendation for the
Microlab. The following has been implemented:

Can openers have been installed in the old lab chem room
attached to ball chain. This will keep them from walking.
Razor blades will be eliminated for scratching the bottle
labels and these can openers will be used instead.

The openers are by the black sink and another by the garbage
can.

Debra will change the manual and send out word to the
lab-users regarding this change in procedure.

Problem: Exit signs off. Batteries destroyed by being fully
         discharged. These were replaced only 3 months ago
         as they were found not working.

Cause:   Cssem operators are going into the breaker panels
         and turning off the EXIT circuit to increase viewing
         contrast.

Solution:The breaker is back on. DOFM will be called to again
         replace the batteries. cssem operators should not
         interfere with the EXIT signs. This is a violation
         of the law. Another method of increasing contrast
         should be found, perhaps the addition of a small hood.

TO ALL LAB USERS:

Please dispose of all needles and razor blades in the jar 
provided in the old lab chem room sink. The jar is labeled
for such puposes.

Please dispose of all broken glassware in the galvanized
pale labeled "Broken Glassware".

The above procedures must be observed and are safety related.
Our custodian has sent us a message that these procedures are
not always followed. Please observe them!

>>> 'safety' problem from bob -- Tue Jan 30 07:51:19 1990 <<<

To: All Lab Users

Please dispose of all razor blades in the containers provided. Currently
there is one container in the chem room above the black sink. Additional
containers are being placed in GL-2 and V-1. These will be labeled for
razor blade disposal.

In addition, please dispose of all used hypodermic needles in these same
containers.

Broken glass should be disposed of only in the galvenized can provided
for such purpose. It is in the old lab.

The above procedures protect our custodial staff and provide for a safe
working environment. Your cooperation is appreciated.

Safety problem: Oil slick in the center of the hallway directly
                in front of the double doors leading into the
                old lab.  The slick continues into the old lab
                as well. Caution: floor surface is very slippery.

The oil was cleaned up and parrish placed a oil tray under the mech
pump of the hld to catch the leaking oil.  This will stop oil from
dripping onto the floor.

Rod Warren of EH&S-Radiation Safety came by this morning and checked over 
N2 blow off guns. In addition he has removed iona as a potential ionizing
radiation source due to it being decomissioned.

All Microlab ionizing radiation sources have been checked and determined
to have zero leakage.

The quartz pushrods on the lberg furnaces have all been fire plished
to prevent injury. Recently a student wroking in this area was cut
on the forehead by a sharp edge on one of these rods. All corner
are now "soft".

I checked for ozone and a few other noxious gases in GL-4 a couple
of months ago with some badge-type monitors.  These are chemically
treated papers which are designed to change to a certain color when
the ambient concentration reaches a certain level.  The monitors
are cumulative in effect, i.e., they integrate the concentration
they have been exposed to.

The bottom line is that the concentration of ozone in GL-4 is below
0.1ppm.  After twenty-four hours there was a color change on the edges
of the indicators.  If there were 0.1ppm or higher concentration of
ozone, the paper would have changed color within one hour.

Regarding skin exposure, we can try to better shield the beam.  I did
have a plexiglass plate made for the Microstepper which blocks 248
spraying off the diffuser at the illuminator.  I understand that the
effects of 248 on skin are also cumulative.  I have started wearing
a face shield when the laser is running.

As an aside regarding ozone, when George Schwartzkopf was here he
told me that copiers emit a tremendous amount of ozone!!  The smell
which I had attributed to the toner is actually O3 in high concentration.
At least we/I cannot smell the amount of ozone in the lab.

There are two safety carriers in the front of the lab by the 
chemical storage. Neither of these will hold an accetone bottle.
The ID of the carrier is less than the bottle O.D.

Problem: Broken glass on the floor of CG1, service chase next to GL1.

Cause: Who ever broke the glass container did not do a thorough job
       in cleaning it up.  The result was that someone got cut, parrish,
       on the glass while changing the pump oil on the semi.

Solution: The glass was vacuumed up and parrish attended to his knee.
 
        *Please in the future when you break glass items clean the
         surrounding area thoroughly*

Problem: Water leak under by randex area.

Cause: A drain hose was out of the drain and spilling on the floor.

Solution: The hose was replaced in the drain and the water cleaned up.
