16E / 16E-H / 16E-P Spray Gun

MAN 96150 EN 01
Ear Protection
The noise emission of greater than 85 dB caused by the spray gun
can damage hearing. Personal protective equipment in accordance
with a hearing conservation program is necessary. The HVOF spray
process can produce noise levels as high as 136 dB.
Ventilation and Exhaust
All thermal spray processes produce fumes and dust particles from the
materials being sprayed. To avoid the effects of dust and fumes gener-
ated by spraying, a suitable spray booth and sufficient exhaust system
are required. Proper installation, operation and maintenance are
important for system performance and maintaining a safe working
environment. For additional safety, dust collectors should be provided
with blow-out or relief panels in case of explosion. All local, state, and
national fire codes must be complied with when determining the loca-
tion of the exhaust system. The exhaust duct of the ventilation system
should be vented to the outside of the building.
The combustion and HVOF spray processes generate carbon dioxide,
carbon monoxide, NOx, dust, and fumes that can damage the respira-
tory system or cause death. An adequate exhaust and ventilation sys-
tem is required. A minimum air velocity of 90 m/min (300 ft/min) is
recommended in the areas adjacent to the spray gun and the object
being coated.
In addition to proper booth ventilation, appropriate personal respiratory
equipment must always be used when the operator is near the spray
process. An industrial hygienist should be consulted for recommenda-
tions on type and fit. Consult the Material Safety Data Sheet (MSDS)
for the products being sprayed for specific information regarding
chemical composition of the powder and Permissible Exposure Limits
(PEL).

combustion and HVOF spray process.
