2.3 Threshold Limits for Air Concentration of Hazardous Material
WARNING Obtain up to date, exact figures from your governmental health agency.
CERTAIN SOLVENTS : Certain solvents may decompose when exposed to ultra
violet rays. Avoid exposing solvents, or parts when wet with solvent, to the radiation
from the arc.
When the electric arc spray system is set up and operated in accordance with the
instructions in this manual, the metalizing wires are electrically energized only when the
gun is spraying. When the spray is shut off, electrical charge is removed from both
metalizing wires.
DANGER If, while the gun is spraying, a person should touch both energized wires,
or any part that the wire is in contact with, that person could receive an electrical shock,
the volume and current of which are capable of developing a harmful or fatal electric
shock or burns.
Do not clean the inside of the power supply unit with a wire brush or any other tool. Use
clean, dry compressed air only.
2.4 Personal Protection
WARNING The electric arc generated at the front of the gun is very bright and emits
ultraviolet light rays. The eyes and skin must be guarded against these rays. Standard
air fed welding, or sand blasting, personal protection equipment fitted with a dark lenses,
has proven to provide adequate protection for thermal spraying.
Possible allergic reaction of dust, fumes, and the like or other unknown causes of health
impairment due to contact with the body cannot, in most cases, be predicted. To avoid
such reaction, never permit spray dust to enter the eyes, mouth, cuts, scratches, or open
wounds. After spraying, and especially before eating or handling foods, wash hands
thoroughly. Wear fireproof or flame resistant protective clothing if available. Protect
eyes, ears, and skin through use of gloves, facemask, ear and body protectors that are
standard in the welding industry.
REDUCTION OF NOISE HAZARDS:
Noise from a Thermion Inc. arc spray gun range between 80 and 120 decibels. At this
level, most Governmental Health Agencies require ear protection and sometimes double
ear protection.
