Safety Equipment
Scene 10:
Vacuum pumps must always
carry a BELT GUARD!
It is desirable
(but not presently required)
that the pump exhaust be
vented to the hood!
Scene 11:
Cylinders, with gases under high pressure,
must be anchored
using a cylinder support.
The above scene shows
IMPROPER
anchoring of the cylinder.
If a poorly supported cylinder falls over,
the upper valve will probably rupture,
and the cylinder will become a torpedo!
Fatalities are quite likely.
The following scene shows
a properly supported cylinder.
Scene 12:
If a cylinder is to be moved,
MAKE SURE A VALVE COVER
is in place!
Move the cylinder ONLY with
a cylinder cart!
- What's GOOD:
- Valve cover in place
- Cylinder cart being used
- What's BAD:
- Chain strap does not offer adequate support
- Additional restraint is needed in this particular case.
Scene 13:
Bulk Flammable Solvents
must be stored in an approved
SOLVENT STORAGE CABINET,
- not in the hood
- not below the sink
- not under the hood
- not on the benchtop
The STORAGE CABINET
must be latched when not in use,
especially overnight.
Scene 14:
Only approved laboratory refrigerators
may be used.
Generally, these will be EXPLOSION PROOF!
Or
"approved for FLAMMABLE MATERIALS STORAGE"
- The following scene shows proper storage practices in a
- laboratory refrigerator.
- all chemicals labeled
- care taken so that the labels do not drop off
- neat, orderly arrangement
- defrost more often than once every 10 years
- Don't store unsealed cans of flammables such as ethyl ether in a refrigerator, even if it is explosion proof.
Store your lunch elsewhere!
Scene 15:
Fire Doors
The doors to each lab are
Class A FIRE DOORS
(gypsum filled).
They will contain a raging blaze for 1 full hr.
Obviously, propping the door open
defeats this purpose
