Personal Protective Equipment
• Examples of PPE:
– Eye (safety goggles, glasses)
– Face (safety shields)
– Head (hard hat)
– Feet (safety shoes)
– Hands and arms (gloves)
– Hearing (earplugs, muffs)
– Respiratory (respirators)
5
Eye Protection
• Wear goggles or face shield around:
– Flying chips or particles;
– Electrical sparks;
– Chemical gases or vapors;
– Harmful light;
– Fertilizer solutions, acids, pesticides, etc;
– Dust
– Swinging objects like ropes or chains
6
Safety Glasses
• Made with metal/plastic frames
• Side shields may be needed
• Used for moderate impact particles
7
Safety Goggles
• Protect the eyes from impacts, dust,
and splashes.
8
Eye Protection
• Goggles only provide eye protection,
however face shields protect the whole
face.
• Be certain the protective eyewear is
approved against the hazard for which it is
being used.
9
Keeping Eyewear Clean
• Eyewear should be clean and defogged
• Clean lenses thoroughly with soap and
water
• Disinfect eyewear that has been exposed
to a hazardous substance or worn by
someone else
• Store and clean eye wear in a closed,
dustproof case (plastic bags).
• Discard pitted or scratched eyewear

11
Head Protection
• Hard hats protect the head on overhead
objects and from falling or flying objects:
– Working below other workers or machinery ,
such as a bucket lift.
– Working in or under trees with work overhead
– Working around or under conveyor belts
– Working around exposed energized
conductors
12
Hard Hats
• Wear hard hats made of slow burning,
water-resistant molded plastic.
– The hard outer shells resist blows and
penetration from above
– Shock absorbing suspensions (headband
and straps) act as an impact barrier
between hat and head
– Slow-burning materials protect against fires
and electrical burns
13
Levels of Hard Hat Protection
Class
Level of Protection
A
Resists impact and penetration
Provides limited resistance to electricity
B
Resists impact and penetration
Provides high resistance to electricity
C
Resists impact and penetration only
No resistance to electricity
14
Hard Hat Inspection
• Inspect the hard hat before use
– Look for:
• Headband stretched or worn
• Headband fits comfortably
• Shell is dented, cracked, or visibly damaged
– Check hard hat after use, if damaged, discard
it
– Wash the shell frequently with hot soapy
water
– Store hats in a cool, dry place
15
Protecting Legs and Feet
• Legs and feet injuries:
– Cuts from cutting equipment
– Heavy objects that might fall on feet
– Sharp objects such as nails or spikes
– Hot or wet surfaces
– Slippery surfaces
16
Leg Protection
• Chainsaw chaps
– Protect legs from injury when using tools such
as chainsaws.
17
Foot Protection
• Safety shoes should be impact resistance
with steel toes.
• Safety-toe shoes are nonconductive and
prevent your feet from completing a circuit
• Shoes with good tread provide traction on
slippery surfaces
18
Hand Protection
• Gloves can protect
hands and forearms
from cuts, abrasions,
burns, punctures,
contact with
hazardous chemicals,
and electric shock
19
Using Gloves
• Choosing the right glove for the job is
important
– Example: Choosing a cotton glove to work
with chemicals is a bad choice.
• Some situations are not appropriate for
gloves such as working with moving
machinery
20
Levels of Glove Protection
Type of
Glove
Metal mesh/
Kevlar
Leather
Level of Protection
Prevents cuts from sharp objects
like blades, cutter bars.
Handling stones or wood chips,
sparks, moderate heat
Cotton fabric Dirt, splinters and abrasion; not
for working with sharp materials
Rubber, vinyl Protects from chemical being
neoprene
used or handled.
21
Noise
• Noise in the workplace interferes with
communication and disrupts concentration
• Sound is measured in decibels
• Noises of 85 decibels or greater affects
your hearing if you work around it for eight
hours a day.

Hearing Protection
• When noise exposure cannot be controlled
by either engineering controls, use hearing
protection.
• Earmuffs and earplugs can reduce noise
levels if used properly.
• It is a good idea to use hearing protection
when average noise levels exceed 80 dB.
24
Hearing Protection Devices
• Formable earplugs:
– Spongy, soft compressed, or
shaped prior to insertion
– Disposable-not for reuse
• Pre-molded ear plugs
– Molded to fit ear
• Earmuffs
– Adjustable headband with soft
cups that seal around the ear
25
Protecting Yourself
• This worker is taking
no chances when it
comes to protecting
himself from the
hazards of hedge
trimming.
26
Protection for Pesticide Application
• Types of exposure when using pesticides:
– Dermal – Getting pesticide on your skin
– Oral – Swallowing pesticide
– Inhalation – Breathing in pesticide
– Ocular – Getting pesticide in the eyes
• Dermal exposure is the most common
• PPE should be worn to reduce skin exposure
27
What A Chemical Label Tells You
• The label on the pesticide includes:
– The chemical formulation
– Signal words: Warning, Caution
– Precautions
– PPE recommendations
– Application method
– Projected length of exposure
28
Read the Label!

Respiratory Protection
• Activities that may require respiratory PPE:
– Handling and applying pesticides
– Working around heavy dust in greenhouses
– Working around mold
– Spraying paint
– Using solvents or other chemical irritants
– Working around allergens
31
Types of Respirators
• Three types of respirators for normal work
activity:
– Particulate respirator
• Use a filter to trap solid particles like dust or mold
– Gas/vapor respirators
• Use a cartridge to absorb gases and vapors
– Combination respirators
• Have a filter for particles and a cartridge for gas
and vapor
32
Selecting a Respirator
• Particulate respirators
• Gas/Vapor respirators
– Type 95 = 95 %
efficient; appropriate
for most dust, mold, or
mist
– Type 97 = 97%
efficient; higher level
of protection
– Type 100 or HEPA =
99.7% efficient; used
with highly toxic
substances
– White = Acid gas
– Black = Organic
vapors
– Green = Ammonia gas
– Yellow = Acid gas and
organic vapor
– Olive Green = Multigas combinations

Dust Masks
This “dust mask” is not
approved for respiratory
protection.
NIOSH approval info
35
Fit Testing
• Positive pressure test
– Block off the exhalation valve with the palm
of your hand,
– Gently exhale, then hold it for 10 seconds,
– Smile, then open your mouth.
– A slight bulge and no air leaks is a proper fit.
• Negative pressure test
– Place the palms of your hands over the
cartridge openings, and gently inhale,
holding your breath for 10 seconds.
– Smile, then open your mouth. If the facepiece is collapsing slightly and you don't
detect any air leaks, you have a proper fit.
36
Cleaning and Storing Respirators
• Respirators should be cleaned after each
use except disposable respirators or dust
filter masks.
• Wash reusable face pieces and the
inhalation and exhalation valves with a mild
disinfecting soap. They should be rinsed and
air dried before storing.
• Store clean, dry respirators in a zip-sealed
plastic bag in a cool, dry cabinet specifically
designated for storage.
37
Respiratory Protection Program
• Your employer should have a written
Respiratory Protection Program
• It includes:
– When a respirator is required
– Medical evaluations needed
– How to select a respirator
– How to use respirators
• Review your employers RPP
38
Training
• Employees required to use PPE must be
trained to know at least the following:
• When PPE is necessary;
• What type of PPE is necessary;
• How to properly put on, take off, adjust, and
wear;
• Limitations of the PPE;
• Proper care, maintenance, useful life and
disposal.

Summary
• Using eye and face protection when debris
is flying around is recommended
• Use head, leg, hand, and foot protection
when using a chainsaw

tools
• Respiratory protection may be
recommended during certain job activities,
check with chemical labels or your
employer for details
