Your Hands
Your hands – don’t take them for granted
Human hands are unique and one of
our greatest assets.
Can you imagine not being able to
work with your hands?
Hand injuries can vary from minor cuts
or irritation to amputations.
5
Hand Injuries
A hand injury can ruin your day or your life
About 20% of disabling
workplace injuries involve
the hands.
Hand injuries include cuts,
burns, fractures, amputations,
nerve damage and dermatitis.
Skin irritation, dermatitis and
even poisoning can occur by
handling chemicals with bare
hands.

MITIGATE THE IDENTIFIED
HAZARDS
10
Engineering Controls: The Preferred Method


Engineering Controls are built into an
operation and require no activation from
the employee. Essentially Engineering
Controls eliminate the hazard.
Examples include guards, self-capping
syringe needles, ventilation systems,
fume hoods and substitution to a less
hazardous process or chemical.
11
Administrative Controls: Second Line of Defense



Administrative Controls are
changes in work practices and
procedures implemented to reduce
exposure.
Less effective method used when
engineering controls are not
feasible.
Examples include written operating
procedures, training, signs, and
limiting exposure times.
12
Last and Least: Personal Protective Equipment (PPE)
 PPE is the last line of defense
 The hazard is still there.
 The PPE places a relatively thin
barrier between you and the hazard.

Other Considerations Before
Selecting a Glove
14
Glove Limitations
 Gloves can get caught in rotating machinery.
 Some people are allergic to latex gloves.
 Gloves can actually cause more problems if
chemicals get inside glove.
 Gloves can fail in conditions of extreme
temperatures, high mechanical force, high
vibration or handling extremely harsh chemicals.

Glove Use & Care
Your hands should be clean before
using gloves.
Fabric and leather gloves should be
cleaned regularly or discarded.
Latex gloves should not be used
by latex-sensitive people.
18
Glove Use & Care
Some common-sense rules about gloves
Replace gloves if they have cuts,
tears, holes or defects.
Make sure gloves are the right
length for the job.
19
Glove Use and Care
Use the right glove for the job
Don’t use fabric or leather gloves to handle
liquid chemicals.
No!
Yes!

Chemical Resistant Gloves
31
The kind of chemical determines the hazard
Corrosives – will burn or irritate
the skin
Solvents – will dry the skin out, may
irritate, burn or blister, some are
absorbed into the body
Pesticides – absorbed into the
body
Other chemicals – a variety of effects
32
Chemical-resistant gloves facts
Chemical-resistant gloves are
not totally “chemical-proof”
Permeation -- Chemicals
penetrate gloves on a molecular
basis without any visible damage.
Degradation -- Chemicals will
also break down (swell, crack or
weaken) the glove material over
time.
Penetration -- Chemicals will
pass through hole and
imperfections in the material.
The thicker the
glove, the more
resistant it is to
chemicals.
Thick is better than Thin
33
Chemical-Resistant Gloves
No single glove material will
Chemical glove selection
protect against all
chemicals.
Gloves are selected according
to the type of chemical.
Good chemical gloves are made of
Viton®, butyl, nitrile, neoprene, or
PVC or combinations of these.
34
Using chemical-resistant gloves
You should know what chemical
you are handling and how long the
gloves will keep the chemical out.
Throw away gloves whenever
degradation is visible or you know
chemicals have leaked inside.
When handling highly toxic chemicals,
two layers of chemical-resistant gloves
can provide additional protection.
35
To determine what glove material is best for a specific chemical.
Consult a compatibility table, proved by glove manufacturers.

Removing Contaminated Gloves
Remove contaminated gloves safely and properly
Badly contaminated gloves
are impossible to clean.
Removal should be done in a
way so that the bare hands
do not touch the outside of
the gloves.
