4.c. When not cutting or gouging, make certain no part of the elec-

trode circuit is touching the work or ground. Accidental contact
can cause overheating and create a fire hazard.

4.d. Do not cut or gouge tanks, drums or containers until the proper

steps have been taken to insure that such procedures will not
cause flammable or toxic vapors from substances inside. They
can  cause  an  explosion  even  though  they  have  been
“cleaned.”  For  information  purchase  “Recommended  Safe
Practices  for  the  Preparation  for  Welding  and  Cutting  of
Containers  and  Piping  That  Have  Held  Hazardous
Substances”,  AWS F4.1  from  the  American  Welding  Society
(see address above).

4.e.  Vent  hollow  castings  or  containers  before  heating,  cutting  or

gouging. They may explode.

4.f.  Do nor fuel engine driven equipment near area where plasma

cutting or gouging.

4.g.  Sparks  and  spatter  are  thrown  from  the  plasma  arc.  Wear

safety glasses, ear protection and oil free protective garments
such  as  leather  gloves,  heavy  shirt,  cuffless  trousers,  high
shoes and a cap over your hair. Wear ear plugs when cutting
or gouging out of position or in confined places. Always wear
safety  glasses  with  side  shields  when  in  a  cutting  or  gouging
area.

4.h. Connect the work cable to the work as close to the cutting or

gouging area as practical. Work cables connected to the build-
ing  framework  or  other  locations  away  from  the  cutting  or
gouging  area  increase  the  possibility  of  the  current  passing
through  lifting  chains,  crane  cables  or  other  alternate  circuits.
This  can  create  fire  hazards  or  overheat  lifting  chains  or
cables until they fail.

4.I.  Read  and  follow  NFPA  51B “  Standard  for  Prevention  During

Welding, Cutting and Other Hot Work”, available from NFPA, 1
Batterymarch Park,PO box 9101, Quincy, Ma 022690-9101.

6.a.  Turn  off  input  power  using  the  disconnect
switch  at  the  fuse  box  before  working  on  the
equipment.

6.b.  Install  equipment  in  accordance  with  the  U.S.  National

Electrical Code, all local codes and the manufacturer’s rec-
ommendations.

6.c. Ground the equipment in accordance with the U.S. National

Electrical Code and the manufacturer’s recommendations.

5.a. Use only compressed gas cylinders contain-
ing  the  correct  gas  for  the  process  used  and
properly  operating  regulators  designed  for  the
gas  and  pressure  used.  All  hoses,  fittings,  etc.

should be suitable for the application and maintained in good
condition.

5.b.  Always  keep  cylinders  in  an  upright  position  securely

chained to an undercarriage or fixed support.

5.c. Cylinders should be located: 

• Away from areas where they may be struck or subjected to

physical damage. 

• A safe distance from plasma cutting or gouging, arc weld-

ing operations and any other source of heat, sparks,
or flame.

5.d.  Never  allow  any  part  of  the  electrode,  torch  or  any  other

electrically “hot” parts to touch a cylinder.

5.e. Keep your head and face away from the cylinder valve outlet

when opening the cylinder valve.

5.f.  Valve  protection  caps  should  always  be  in  place  and  hand

tight  except  when  the  cylinder  is  in  use  or  connected  for
use.

5.g.  Read  and  follow  the  instructions  on  compressed  gas  cylin-

ders,  associated  equipment,  and  CGA  publication  P-l,
“Precautions  for  Safe  Handling  of  Compressed  Gases  in
Cylinders,”available  from  the  Compressed  Gas  Association
1235 Jefferson Davis Highway, Arlington, VA 22202.

8.a.  Electric  current  flowing  through  any  con-
ductor  causes  localized  Electric  and  Magnetic
Fields  (EMF).  Cutting  or  gouging  current  cre-
ates EMF fields around torch cables and cutting
machines. 

8.b. EMF fields may interfere with some pacemakers, so opera-

tors  having  a  pacemaker  should  consult  their  physician
before cutting or gouging.

8.c. Exposure to EMF fields during cutting or gouging may have

other health effects which are now not known.

8d. All operators should use the following procedures in order to

minimize exposure to EMF fields from the cutting or gouging
circuit:

8.d.1. Route the torch and work cables together - Secure

them with tape when possible.

8.d.2. Never coil the torch cable around your body.

8.d.3. Do not place your body between the torch and

work cables. If the torch cable is on your right side,
the work cable should also be on your right side.

8.d.4. Connect the work cable to the workpiece as close as

possible to the area being cut or gouged.

8.d.5. Do not work next to cutting power source.

7.a. Keep your body away from nozzle and

plasma arc.

7.b. Operate the pilot arc with caution. The pilot arc is capable of

burning the operator, others or even piercing safety clothing.
