ensure that all the glassware is properly cleaned according to
the procedure.
If chemical cleaning is necessary, monitor the
process to ensure that all safety measures are adhered to.
Directly relating to this is ensuring that used solutions are
disposed of in an appropriate container.

if not handled properly.
Broken or damaged containers must be

in
accordance
with
established
safety
and
environmental procedures.
You must ensure that all spills are
cleaned up immediately and hazardous materials and waste are
disposed of in accordance with the laboratory SOP.
It is your
responsibility to ensure that all technicians know how to safely
conduct themselves in the laboratory.
The laboratory SOP, FM
10-67-2, and MSDS along with other pertinent guidelines must be
used as guides to handling chemicals properly and safely.
Everyone shares the responsibility of preventing injury to
himself and to others, as well as preventing damage to the
environment.
For a detailed explanation of relevant safety
measures, please refer to FM 10-67-2, Chapter 10, Section I.
Other guidance for handling chemicals may be found in the MSDS
and the laboratory SOP.
