Proper use
Proper Use

  • Pre-use Inspection

  • Proper Donning

  • In-use Consideration:

    • Avoid Contamination

    • Periodic Inspection

    • Know Limitations

  • Proper Decontamination/Doffing

  • Cleaning and Storage

B461 Course


Limitations
Limitations

  • No Clothing Material Resistant to all Chemicals

  • Decreased Manual Dexterity/Mobility

  • Impaired Vision

  • Heat Stress

  • All Affect Worker Safety and Efficiency

B461 Course


Decision factors
Decision Factors

  • Chemical Resistant/Other Performance Requirements

  • Amount/Length of Exposure

  • Hazardous Properties of Chemicals Involved

  • Work Function/Application

B461 Course


Protective materials

Tyvek

Nomex

Polyethylene

Saranex

Nitrile

Polyvinyl Alcohol (PVA)

Butyl Rubber

Neoprene

Chloropel

Natural Rubber

Viton

Polyvinyl Chloride (PVC)

Protective Materials

B461 Course


Heat and physical stress
Heat and Physical Stress

  • Any use of CPC&E Increase Heat and Physical Stress

  • All CPC can Cause Heat Stress Conditions

  • Wearing CPC&E also Increases Risk of Accidents

  • Selecting Level A (Over B,C) should be Balanced Against the Probability of Stress and Accidents

  • Employee Heat & Physical Stress should be Monitored by the Hospital Safety Officer

B461 Course


Chemical resistance charts
Chemical Resistance Charts

  • Available from Manufacturers/Independent Labs

  • Majority Reflect Ability to Resist Degradation (Qualitative)

  • Limited Permeation Data (Quantitative)

  • Useful if Applied with Discretion in Conjunction with Proper Hazard Evaluation

B461 Course


Inspection procedures
Inspection Procedures

  • Before Wearing Any CPC&E It Should Be Properly Inspected

  • Create a Checklist for Visual Inspections

  • Suit Should Be Inspected Immediately Before Use

  • Monthly When Not in Use

B461 Course


Inspection procedures1
Inspection Procedures

  • Spread suit out on a flat surface

  • Examine the outside for the following:

    • Fabric for abrasions, cuts, holes, or tears

    • Fabric has retained the original flexibility and durability

    • Seams for separation or holes

    • Zippers, buttons, storm flaps, and other connecting devices for proper sealing and operation

B461 Course


Inspection procedures cont d
Inspection Procedures (cont'd)

  • Inside a dark room:

    • Use flashlight inside of the suit

    • Look for pinpoints of light from outside the suit

  • Refer to manufacturer’s recommendations for:

    • Routine, and/or

    • Special inspection procedures

B461 Course

Inspect Respirator Equipment

  • Components

    • Face-piece

    • Breathing tube

    • Hood

  • Cartridges

  • Belt and snaps

  • Cleanliness

  • Batteries

    • Flow check (4-6 cfm)

B461 Course


Respirator fit testing
Respirator Fit Testing

  • Seal of face-piece

    • Most important factor

  • Fit test with respirator

    to be used

  • Types of fit testing:

    • Qualitative

    • Quantitative

    • OSHA Regulation

      • 29 CFR 1910.134
