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 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.
