Definition
Devices used to protect an employees from injury or illness resulting from contact with chemical, radiological, physical, electrical, mechanical, or other workplace hazards (OSHA)
The need for PPE and the type of PPE used is based on hazard present; each situation must be evaluated independently
Caveats
PPE is used as a last resort The use of PPE signifies that the hazard could not
be controlled by other methods, such as– administrative controls (i.e., shift rotation)– engineering or industrial hygiene controls
A Simple View
PPE – Some Uses
Head protection Eye and Face protection Hearing protection Respiratory protection Arm and Hand protection Foot and Leg protection Protective clothing
PPE – Head Protection
Falling objects Bumping head
against fixed objects such as exposed
pipes or beams Contact with
exposed electrical conductors
PPE – Head Protection
Class A General service
e.g., mining, building construction, shipbuilding, lumbering, and manufacturing
Good impact protection but limited voltage protection
PPE – Head Protection
Class B Electrical work Protect against falling objects and high-voltage shock
and burns
PPE – Head Protection
Class C Designed for comfort, offer limited protection Protects heads that may bump against fixed objects,
but do not protect against falling objects or electrical shock
PPE – Eye Protection
Eye Protection - Selection Safety glasses are used to protect the eyes from flying
objects (no face protection) Made with metal/plastic safety frames Used for moderate impact from particles produced
by such jobs as carpentry, woodworking, grinding, and
scaling
Eye Protection - Selection Chemical splash goggles
Chemical splash goggles protect against fluids by sealing tightly against the face
Protect eyes, eye sockets, and the facial area immediately
surrounding the eyes from impact, dust, and splashes
Eye Protection - Selection Welding Shields:
Protect eyes from burns caused by infrared or intense radiant
light, and protect face and eyes from flying sparks, metal spatter, and slag chips produced during welding, brazing, soldering, and cutting.
Face Shield the highest level of face
protection Protect the face
from nuisance dusts and potential splashes
or sprays of hazardous liquids
Hearing Protection Basics Noise induced hearing loss can occur with exposures >90
dBA A hearing conservation program becomes a requirement at
exposures >85dBA Higher levels of noise exposure have shorter allowable
exposure times
Noise levels versus Duration Sound Level (dBA) 90 92 95 100 105 110 115
Exposure (hours) 8 6 4 2 1 0.5 0.25
Hearing Protection Rule of Thumb
if you cannot carry on a conversation in a normal tone of voice with someone at arm’s length, you are likely near 90dBA
All hearing protection devices should have a Noise Reduction Rating (NRR) = # of decibels they will reduce noise levels
Be conservative when using NRRs
Hearing Accident Example 1
Ear plugs with NRR of 25 dBA exposure = 105 dBA 105 minus 25 = 80 dB therefore okay
Example 2 same plugs exposure = 125 dBA 125 minus 25 = 100 dB not acceptable; must be below
90 dB
Arm and Hand Protection Burns Bruises Abrasions Cuts Punctures Fractures Amputations Chemical Exposures
Types of Gloves Norfoil laminate resists
permeation and breakthrough by an array of toxic/hazardous
Chemicals. Butyl provides the highest
permeation resistance to gas or water vapors; frequently used
for ketones (M.E.K., Acetone) and esters (Amyl Acetate, Ethyl
Acetate etc.).
Types of Gloves Viton is highly
resistant to permeation by chlorinated and aromatic solvents.
Nitrile provides protection against a
wide variety of solvents, harsh chemicals, fats and petroleum products and also provides excellent resistance to cuts, snags, punctures and abrasions.
Types of Gloves Kevlar
protects against cuts, slashes, and abrasion.
Stainless steel mesh Protects against cuts and
lacerations.
Foot and Leg Protection
Foot Injury - Cause Heavy objects
such as barrels or tools that might roll onto or fall on employees’ feet
Sharp objects such as nails or spikes that might pierce the soles or uppers of
ordinary shoes Molten metal that might splash on feet Hot or wet surfaces Slippery surfaces
Protective Footwear Have impact-resistant toes and heat-resistant soles
that protect against hot surfaces common in roofing, paving, and hot metal industries
Some have metal insoles to protect against puncture wounds May be designed to be nonconductive to protect from workplace
electrical hazards
Other Protective Clothing
body injuries - causes Intense heat
Splashes of hot metals and other hot liquids Impacts from tools, machinery, and materials Cuts Hazardous chemicals Contact with potentially infectious materials, like blood Radiation
Body Protection
Respiratory Protection Protects users
by removing harmful materials that may enter the body via the lungs
Inhalation is one of the Quickest most efficient ways to introduce lethal levels of hazardous
materials into the body
Respirators - types Self Contained Breathing Apparatus (SCBA)
Advantages Provides highest level of protection against airborne
contaminants and oxygen deficiency Limitations
Bulky and heavy Limited air supply limits work duration May impair movement in confined space
Respirators - types Self Contained Breathing Apparatus (SCBA)
Advantages: Provides highest level of protection against airborne
contaminates and oxygen deficiency Limitations:
Bulky and heavy Limited air supply limits work duration May impair movement in confined space
Recap PPE is hazard specific; the hazards of each
workplace and task must be evaluated PPE is used as a last resort when the hazard cannot
be controlled by other methods Supervisors are responsible to ensure it is available
and worn; Employees must wear and maintain their PPE
