3.4 General Workplace Dangers
Please refer to the figure Figure 4.1 [}15] for the location of parts mentioned in this section.
CAUTION
Risk of contamination from toxic liquids or vapors during operation.
Contamination may occur from sample liquid leaking into the laboratory environment.
u Clean any chemical leakages or spills immediately following all appropriate safety
precautions for safe chemical handling and laboratory cleaning procedures.
u Wear proper personal protective equipment. Examples include but are not limited to
gloves, goggles, lab coat, etc.
u The volume of sample liquid in the reactor must not exceed 2.5 liters.
u Utilize a fume hood over the reactor, fluid pump, and the sample and temperature
control connectors to the reaction transfer line.
u Place a container that can hold up to 10 liters of liquid, and is appropriately rated for
chemical spills, below the probe.
u Only reactions with moderately hazardous products should be carried out. The cleaning
of accidental spillage of sample liquid must be possible using standard safety equipment
(goggles, lab coat, gloves, etc.).
CAUTION
Risk of injury from broken glass during glass flow tube replacement.
Incorrect handling of the glass flow tube during installation may result in broken glass and
possible injury.
u Wear proper personal protective equipment. Examples include, but are not limited to,
gloves, goggles, lab coat, etc.
u Always use the flow tube protector to exchange the glass flow tube (see Mounting the
Glass Flow Tube [}50]).
CAUTION
Risk of contamination from toxic liquids or vapors during service and
installation.
Insufficient cleaning/flushing of the flow unit prior to storage may result in a risk of
contamination from toxic liquids or vapors during service and installation.
u Wear proper personal protective equipment. Examples include, but are not limited to,
gloves, goggles, lab coat, etc.
u Clean and flush the sample line after usage with a suitable solvent that is compatible
with the solubility of all components used in the experiment.
u Seal the inlet and outlet of the sample line and temperature control lines while the
system is outside the magnet and prior to storage.
u Use an inert, non-toxic temperature control liquid like glycol.
