Personal Protective Equipment
• Personal Protective Equipment
– Personnel must be protected from the
hazards at the scene
• OSHA 29 CFR 1910.132 Personal Protective
Equipment
• OSHA 29 CFR 1910.134 Respiratory Protection
• NFPA 472 Standard for Professional Competence
of Responders to Hazardous Materials Incidents

• Personal Protective Clothing Type
– Designed to protect the
• Skin
• Eyes
• Face
• Hands
• Feet
• Body
• Head
• Respiratory System

– Must protect the wearer from
• Heat
• Hazardous materials
– Contacting skin, eyes
– No single ensemble can protect against all
hazards
• Must be concerned when choosing PPE
• Firefighter turn out gear
– Easily penetrated by fumes and vapors

– NFPA 472 identifies three types of protective
clothing:
• Structural fire-fighting protective clothing
• High-temperature protective clothing
• Chemical-protective clothing (CPC)

– Structural Fire-Fighting Protective Clothing
• Protects wearer from
– Heat
– Moisture
– Ordinary hazards associated with structural fire fighting
» Helmet
» Coat
» Pants
» Boots
» Gloves
» PASS Device
» Hood

• Provides limited protection against hazardous
materials
• Neither corrosive-resistant nor vapor-tight
• Any liquids can soak through
• Acids and bases can dissolve (deteriorate) the
outer layers
• Gases can penetrate the garment

• Hazardous materials may permeate any protective
clothing
– Pass through at the molecular level
– Remain in the protective equipment
» Subjects the wearer to repeated exposures
» May render it unsafe for use

• Never clean turn-out gear at
– Home
– Public laundries
– Any place that they might mix with other clothing
• Never wear it into
– Sleeping areas
– Living areas

• Commonly used at hazardous materials incidents
when the following conditions are met:
– Contact with splashes of extremely hazardous materials
is unlikely
– Total atmospheric concentrations do not contain high
levels of chemicals that are toxic to the skin
– There are no adverse effects from chemical exposure to
small areas of unprotected skin
– There is a chance of fire or there is a fire and this
type of protection is appropriate

– High-Temperature Protective Clothing
• Designed to protect the wearer from short-term
high-temperature exposures
– Heat levels exceed the capabilities of standard fire-
fighting protective clothing
• Provides limited use in dealing with chemical
hazards

• Proximity Suits
– Permit close approach to fire for
» Rescue
» Fire-Suppression
» Property Conservation
– Aircraft rescue
– Flammable liquid fires

• Fire-Entry Suits
– Allow a person to work in total flame environments for
short periods of time
» Short-duration and close-proximity protection
• Radiant heat as high as 2,000
o
F
– Each suit has a specific use
» Not interchangeable
– Not designed to protect the wearer against chemical
hazards

• Limitations
– Contributes to heat stress
– Bulky
– Limits wearer’s vision
– Limits wearer’s mobility
– Limits communications
– Requires frequent and extensive training
– Expensive to purchase

– Chemical Protective Clothing (CPC)
• Purpose is to shield or isolate individuals from the
chemical, physical and biological hazards
• NFPA recognizes two types:
– Liquid splash protective clothing
– Vapor protective clothing
• CPC is made from a variety of different materials
– None of which protects against all types of hazards

• Manufacturer must provide a list of chemicals for
which the suit is effective
• May be purchased as a single or multi-piece
garment

• Encapsulating
– Designed to completely cover the responder including
the respiratory equipment
• Nonencapsulating
– Designed to provide protection in conjunction with the
wearer’s respiratory protection
– Attached or detachable:
» Hood
» Gloves
» Boots

• Designed to be impermeable to moisture
– Prohibits heat transfer from body through evaporation
– Causes a safety concern to the wearer
» Hot environments
» Extended work times
» Strenuous work

• The effectiveness of CPC can be reduced by three
actions:
– Permeation
– Degradation
– Penetration

• Permeation
– Occurs when a chemical passes through a fabric on a
molecular level
– Typically no visible evidence of chemicals permeating a
material
– Manufacturers provide charts of breakthrough time

• Degradation
– Chemical Degradation
– Occurs when the characteristics of a material are
altered through contact with chemical substances
» Cracking
» Brittleness
– Most common observations
» Discoloration
» Swelling
» Loss of strength

• Penetration
– Occurs when a hazardous material enters an opening or
a puncture in a protective material
» Rips
» Tears
» Cuts
» Open zippers
» Unsealed seams

• Service Life
– May be labeled for:
» Reusable
• Multiuse
• Repeated use
» Limited Use
• Not disposable
» Disposable
• For one-time use

• OSHA identifies the following emergency
response operations that may require the use of a
CPC
– Site Survey
– Rescue
– Spill Mitigation
– Emergency Monitoring
– Decontamination
– Evacuation

• Written Management Program
– Must reference 29 CFR 1910.120 HAZWOPER
» Policy statements
» Procedures
» Guidelines
– Copies must be made to all personnel who may use CPC
– Two basic objectives:
» Protect the wearer from safety and health hazards
» Prevent injury to the wearer

• Written Management Program
– Should include the following elements:
» Hazard Identification
» Medical Monitoring
» Environmental Surveillance
» Selection, Care, Testing and Maintenance
» TRAINING

• Liquid-Splash Protective Clothing
– Designed to protect users from chemical liquid splashes
– Does not protect against vapors or gases
» Encapsulating
• Single, one-piece garment
• Boots and gloves are sometimes separate
» Nonencapsulating
• One-piece coverall or individual pieces
– May be used in conjunction with respiratory protection

• Vapor-Protective Clothing
– Designed to protect the wearer against chemical vapors
or gases
– Offers a greater level of protection than splash
protective suits
– Must be worn with positive pressure SCBA or SAR
– Tested against 21 challenge chemicals

• Respiratory Protection Types
– Atmosphere-Supplying Respirators
• Provides air from a source other than the
surrounding atmosphere
– Positive-Pressure SCBA
» Closed-Circuit
» Open-Circuit
» Supplied Air Respirator

– Particulate-Removing Filters
• Protects the user from particulates
– Including airborne diseases
• Absolute
– Use screening to remove particles from the air
– Excludes the particles that are larger than the filter’s
pores
• Nonabsolute
– Contain pores larger than the particles

– Vapor and Gas – Removing Filters
• Designed to protect against specific vapors
• Catalyst
– Substance that influences the rate of chemical reaction
• Sorbent
– Material that absorbs or adsorbs

• Respiratory Protection Programs
– Defined in a written document
• Facepiece Fit Testing
– Annually
– Medical clearance is required first
• Medical Testing
– Annual physical

• EPA Levels of Protection
– Level A
• Highest level of protection
– Vapors
– Gases
– Mists
– Particles
• Fully encapsulation suit

– Level B
• Garment that includes an SCBA and provides
protection against splashes
• Worn with a high level of respiratory protection
• Encapsulating
• Nonencapsulating

– Level C
• Splash-protecting garment
• Low level of respiratory protection
– Air-purifying device
– Level D
• Work uniforms, street clothing, coveralls

• Climate Concerns and Health Issues
– Heat Disorders
• Heat Stroke
• Heat Exhaustion
• Heat Cramps
• Heat Rashes
• Heat Fatigue

– Heat-Exposure Prevention
• Fluid Consumption
• Body Ventilation
• Body Cooling
• Rest Areas
• Work Rotation
• Proper Liquids
• Physical Fitness

– Cold Disorders
• Hypothermia
• Trench Foot
• Frostbite

– Medical Monitoring
• Required by NFPA 471
• Conducted:
– Before responders wear PPE
– After they are decontaminated
» Vital signs
» Hydration
» Skin
» Mental Status
» Medical History
– Post medical follow-up is also required
