Protecting Workers
The general requirements for the protection of thermal spraying operators
and welders are the same as those published in
ANSI/AWS Z49.1, Safety
in Welding and Cutting; ANSI Z87.1, Standard Practices for
Occupational and Educational Eye and Face Protection; ANSI Z88.2,
Standard Practices for Respiratory Protection; and ANSI Z89.1,
Standard Practices for Industrial Head Protection with Low Voltage
Hazards.
1.5.1 Eye
Protection
Spraying and blasting operations require eye protection in the form of
helmets, hand shields, face shields, or goggles. See
ANSI Z87.1 and
Z89.2
for recommendations. Operators
MUST
use protection against
infrared and ultraviolet radiation and flying particles. Provide all helpers
and adjacent operators with suitable eye protection as well. Equip the eye
protection with a suitable filter plate to protect against ultraviolet, infrared,
and intense visible light radiation (see Table 1-1).

In thermal spray operations where additional respiratory protection is not
required, operators may wear eye protecting goggles alone. The goggles
should have indirect ventilating fins to reduce fogging and eliminate
danger from flying particles. In plasma spray operations, replace the
goggles with helmets or hand shields that provide face, chin, and neck
protection from infrared and ultraviolet radiation.
When blasting, use face shields or helmets equipped with dust hoods to
protect eyes, face, chin and neck. Provide respiratory protection, as well
as other protection discussed in the following paragraphs.
