NFPA 30A states that:
“When maintenance to Class I dispensing devices becomes necessary and such maintenance may
allow the accidental release or ignition of liquid, the following precautions shall be taken before
such maintenance is begun:
• Only persons knowledgeable in performing the required maintenance shall perform the work.
• All electrical power to the dispensing device and pump serving the dispenser shall be shut off at
the main electrical disconnect panel.
• The emergency shut-off valve at the dispenser, if installed, shall be closed.

WARNING
Electric shock hazard! More than one disconnect switch may be required to de-energize the
dispenser for maintenance and servicing. Use a voltmeter to make sure ALL circuits in the
dispenser are de-energized. Failure to do so may result in serious injury.
Lockout/Tagout requirements of the U. S. Dept. of Labor, Occupational Safety and Health Adminis-
tration (OSHA) may also apply. Refer to Title 29, Part 1910 of the Code of Federal Regulations
(29CFR1910), Control of Hazardous Energy Source (Lockout/Tagout).
NOTE: To prevent damage to components located in the hydraulic cabinet, dispenser doors should be
in place during rainy and/or icy weather conditions. Also, check the nozzle boot flipper for
freedom of movement. If ice has formed on the flipper, it should be cleared to prevent
unnecessary damage.
