3.2 Grounding
Grounding an object means providing an adequate path for the flow of the electrical charge
from the object to the ground. An adequate path is one that permits a charge to flow from
the object fast enough that it will not accumulate to the extent that a spark can be formed. It
is not possible to define exactly what will be an adequate path under all conditions since it
depends on many variables. In any event, the grounding means should have the lowest
possible electrical resistance. Grounding straps should be installed on all loose conductive
objects in the spraying area. This includes material containers and equipment. Magnum
Venus Plastech recommends grounding straps be made of AWG No.18 stranded wire as a
minimum and the larger wire be used where possible. NFPA Bulletin No77 states that the
electrical resistance of such a leakage path may be as low as 1 meg ohm (10 ohms) but that
resistance as high as 10,000 meg ohms will produce an adequate leakage path in some
cases. Whenever flammable or combustible liquids are transferred from one container to
another, or from one container to the equipment, both containers or container and
equipment shall be effectively bonded and grounded to dissipate static electricity. For
further information, see National Fire Protection Association ( NFPA) 77, titled
“Recommended Practice on Static Electrical”. Refer especially to section 7-7 titled “Spray
Application of Flammable and Combustible Materials”. Check with local codes and
authorities for other specific standards that might apply to your application. NEVER USE
HARD MATERIALS SUCH AS WIRE, PINS, ETC., TO CLEAR A PLUGGED GUN. HARD
MATERIALS CAN CAUSE PERMANENT DAMAGE. DAB WITH A BRISTLE BRUSH,
BLOW BACKWARDS WITH AIR UNTIL CLEAR WHILE WEARING A PROTECTIVE EYE
SHIELD. REPEAT AS MANY TIMES AS NECESSARY. DO NOT PERFORM ANY
MAINTENANCE OR REPAIRS UNTIL YOU HAVE FOLLOWED THE PRECAUTIONS
STATED ABOVE. IF YOU, AS AN EQUIPMENT OPERATOR OR SUPERVISOR, DO NOT
FEEL THAT YOU HAVE BEEN ADEQUATELY TRAINED OR INSTRUCTED AND THAT
YOU LACK THE TECHNICAL KNOWLEDGE TO OPERATE OR PERFORM
MAINTENANCE ON A PIECE OF MAGNUM VENUS PLASTECH EQUIPMENT, PLEASE
CALL MAGNUM VENUS PLASTECH BEFORE OPERATING OR PERFORMING
MAINTENANCE ON THE EQUIPMENT. IF YOU HAVE ANY QUESTIONS REGARDING
THE ABOVE PRECAUTIONS OR ANY SERVICE OR OPERATION PRECEDURES, CALL
YOUR MAGNUM VENUS PLASTECH DISTRIBUTOR OR MAGNUM VENUS PLASTECH.

DANGER: Contaminated catalyst may cause Fire or Explosion. Before working on the
catalyst pump or catalyst accumulator, wash hands and tools thoroughly. Be sure
work area is free of dirt, grease or resin. Clean catalyst system components with clean
water only.
DANGER: Eye, skin and respiration hazard. The Catalyst, MEKP, may cause
blindness, skin irritation or breathing difficulty. Keep hands away from face. Keep
food and drink away from work area.
WARNING: Please refer to your catalyst manufacturer’s safety information regarding
the safe handling and storage of catalyst. Wear appropriate safety equipment as
recommended
