Safety Unit Lesson 2
Objective: Explain and Identify proper personal protection used in welding.
PPE
Each person in the shop wears general work clothing.
Extra protection is needed for each person in
direct contact with hot materials. Depending on the
specific job and conditions, protective equipment
can include.
Body Protection
 Foot Protection
 Hand Protection
 Ear Protection
 Eye, Face, and Head Protection

Basic clothing should offer protection from flying
sparks, heat and Ultra Violet light.
Shirts should have no pockets or a flap over the pocket.
Pants should not be too baggy and no frayed or rolled
cuffs to catch sparks.
Polyester or other synthetic fabrics should never be
worn; sparks can melt these materials causing severe
burns.
Lighters or matches should not be kept in pockets or
near sources of heat or sparks.
Loose fitting clothes, ties, and long hair are hazards to
personal safety especially around rotating equipment.
Long hair and loose fitting clothing
are hazards because they can get
caught in rotating equipment.

Body Protection
Body Protection
Welding Jackets come in 3
basic types.
1. Light weight fire retardant
cloth. Good for light duty
welding or cutting.
2. Medium weight fire
retardant cloth with
leather sleeves. Good for
light welding in the
vertical and overhead
positions.
3. Heavy full leather jacket.
Good for high heat, heavy
duty welding in all
positions especially
overhead.
Polyester or other synthetic fabrics
should never be worn; sparks can
melt these materials causing
severe burns.
A.) True
B.) False
Foot Protection
The Occupational Safety and
Health Administration (OSHA)
requires
that
protective
footwear
be
worn
when
working where falling, rolling
or sharp objects pose a danger
of foot injuries and where feet
are exposed to electrical
hazards.
Foot protection comes in many
forms and usually depends on
the work environment. In the
welding shop environment
smooth top leather boots at
least 8” tall with steel
reinforced safety toe is best.
Foot Protection
Additional foot protection can
be had in the form of Spats or
heavy boots with metatarsal
protection.
OSHA requires work boots to bee at
least _____ inches tall.
A.) 6
B.) 5
C.) 8
D.) 10
Hand Protection
Gloves are the primary type
of hand protection. Gloves
should be chosen based on
the hazards involved in the
work being done.
To protect from UV rays
when welding, gauntlet
type welding gloves should
be worn.
For high heat welding,
heavy duty gloves with
heat reflective coverings
are used.
Hand Protection
Some specially designed
gloves can protect more of
the arm. Others are designed
to protect against extreme
temps.
Some light weight leather
gloves are good for light
GMAW or GTAW welding
with little sparks.
Leather work gloves are good
for general work and handling
metal. Light welding can be
done with caution. The cloth
backs can easily melt from the
heat
generated
during
welding.
Welding gloves need to protect
from
A.) Sparks
B.) Heat
C.) Sharp Metal
D.) All of the above
Hearing Protection
•Hearing loss due to damage
from loud noise is too
common
and
easily
preventable.
•Sound is measured in
decibels (db), normal speech
is around 60 db.
•An increase of 10 db means
the sound is 10 times louder.
• Long or repeated exposure
at or above 85 db can cause
permanent damage and loss
of hearing.
Hearing Protection
There are two basic types of
hearing protection.
•Around the ear protection
such as earmuffs. Generally
considered to be the best
type of hearing and ear
protection.
•Ear plugs which go in the
ear canal and can be
reusable or disposable. The
disposable type ear plug is
the most common.
A combination of both
around the ear and in the ear
can be required in some
extreme
noise
work
environments.
Hearing Protection
Painful
150 dB = rock music peak
140 dB = firearms, air raid siren, jet engine
130 dB = jackhammer
120 dB = jet plane take-off, amplified rock music at
4-6 ft., car stereo, band practice
Extremely Loud
110 dB = rock music, model airplane
106 dB = timpani and bass drum rolls
100 dB = snowmobile, chain saw, pneumatic drill
90 dB = lawnmower, shop tools, truck traffic, subway
Very Loud
80 dB = alarm clock, busy street
70 dB = busy traffic, vacuum cleaner
60 dB = conversation, dishwasher
Moderate
50 dB = moderate rainfall
40 dB = quiet room
Faint
30 dB = whisper, quiet library
Long or repeated exposure at or
above ___ db can cause permanent
damage and loss of hearing.
A.) 65
B.) 85
C.) 25
D.) 55
Eye Protection
Safety glasses will be the
first piece of PPE put on
when entering the shop
when work is being done.
Safety glasses must meet
ANSI Z87 standards to be
approved for use in the
shop.
Safety glasses are your
first line of defense against
eye damage. There are
hazards in the welding
environment which require
additional protection.
Eye Protection
The welding arc is brighter
than the sun and produces
radiation in the form of
Ultraviolet Light.
Flash burn: is a burn to
the eyes from UV light that
can harm unprotected
eyes in just seconds and
can
cause
permanent
damage to the retina.
Oxy-fuel
cutting
or
welding
produces
radiation in the form of
Infrared light. Infrared light
is not as damaging as UV
but can cause permanent
damage if exposed for
long periods of time.
Eye Protection
Welding helmets come in all kinds of shapes, size’s, and colors. Some
helmets come with variable shade lenses that will automatically darken
when the welding arc is struck.
The darkness of the shade or the shade number is dependant on type
of welding and the amount of current being used.
Face and Head Protection
