combustible gases is detected by the system, it automatically starts
and turns on a red warning light.
(2) General Safety. Laboratory personnel and personnel
who handle petroleum products in the field are exposed to the same
hazards. In addition, laboratory personnel are exposed to chemicals.
Also, if an accident occurs, they are exposed to the effects of
vacuum and pressures in close quarters. Efficient laboratory opera-
tions must include all safety considerations. Operating procedures
should be prepared for each laboratory so that emergencies may be
dealt with when they occur.
Consult authority in charge of the laboratory when
in doubt concerning any laboratory procedure
Do not attempt to perform more than one test at a
time, unless each test can be given the proper
attention needed to complete it efficiently and
safely. Give complete attention to tests in
progress. Request assistance from another tech-
nician or notify the supervisor if it becomes
necessary to leave the laboratory for even a brief
period of time.
Do not attempt short cuts or improvisations,
because laboratory procedures have been divised
with a view to quality, efficiency and safety.
Discuss any change to procedures with the super-
Do not engage in any form of horseplay in the
laboratory, because it diverts attention from
testing or other operations in progress, and
contributes to existing hazards.
Never taste a laboratory chemical. Never smell a
chemical except when necessary, and then only by
wafting a small amount of vapor with the hand
toward the nose.
Systematically check the laboratory and its equip-
ment at the end of each day to be sure than no
hazardous situation can develop while the labora-
tory is unoccupied.
Bond and ground the laboratory to minimize po-
tential differences between the objects and the
