Presentation on theme: "PPE: Clothing/Ensembles"— Presentation transcript:
1 PPE: Clothing/Ensembles Instructional Goal:The participant will recognize the purpose of personal protective equipment and personal protective clothing.
2 PPE: Clothing/Ensembles Shield or isolate individuals from waste site hazardsCareful selection and use of adequate PPENo single combination of equipment and clothing is capable of protecting against all hazards
3 Developing a PPE Program Hazard identificationMedical monitoringEnvironmental surveillanceSelection, use, maintenance, and decontamination of PPE
4 Developing a PPE Program TrainingProgram review and evaluationProtective clothing
7 Permeation Rate Clothing material Manufacturing method Concentration of hazardous materialTemperature, pressure and humiditySolubility of the chemical through the clothing material
8 Heat Transfer Characteristics “clo” value is thermal insulation value of the material
9 Work Mission Duration Air supply consumption work rate fitness body sizebreathing patterns
10 Work Mission DurationAmbient temperature - hot and cold temperatures affectvalve operationdurability and flexibility of suit materialsintegrity of suit fastenerspermeation rate of chemicalsconcentration of airborne contaminants
11 Work Mission DurationPermeation and penetration by chemical contaminants into the material of a Suit/EnsembleCoolant supply
12 Selection Summary Durability Flexibility Temperature effects Will the material resist tears, puncture and abrasions?Will the material withstand repeated use after contamination/decontamination?FlexibilityWill the CPC interfere with a worker's ability to perform his or her assigned tasks? (This is particularly important to consider for gloves.)Temperature effectsWill the material maintain its protective integrity and flexibility under the extremes of heat and cold?
13 Selection Summary Ease of decontamination Are decontamination procedures available on site?Will the material pose any decontamination problems?Should disposable clothing be used?Compatibility with other equipmentDoes the clothing prevent the use of another, necessary piece of protective equipment (e.g., suits that preclude hardhat use in a hardhat area)?Duration of useCan the required task be accomplished before contaminant breakthrough occurs, or before degradation of the CPC becomes significant?
15 Level A - Maximum skin and respiratory protection Personal Protective Equipment Levels of ProtectionLevel A - Maximum skin and respiratory protectionLevel B - Maximum respiratory with some skin protectionLevel C - Limited level of respiratory protection and skin protection from airborne hazardsLevel D - No respiratory protection and limited skin protection from airborne hazards
16 Personal Protective Equipment Levels of Protection Level Afully-encapsulatingmaximum skin and respiratory protectionNOTE: recommended for site entries if operations involve high potential for slash or for exposure to vapors, gases or particles that have high degree of hazard to the skin.
17 Personal Protective Equipment Levels of Protection Level Bmaximum respiratory protectionsome skin protectionNOTE: This is the minimum level recommended for initial site entries until the hazards have been further identified.
18 Personal Protective Equipment Levels of Protection Level Climited level of respiratory protectionskin protection from airborne hazardsNOTE: can be used only when all atmospheric contaminants have been identified and their concentrations measured and when it has been determined that the air-purifying respirator can remove the contaminants.
19 Personal Protective Equipment Levels of Protection Level Dno respiratory protectionlimited skin protection from airborne hazardsNOTE:can be used only when all atmospheric contaminants have been identified and concentrations measured, and when it has been determined that there is no hazard to the respiratory system or to the skin.
20 Reasons to Upgrade PPE Dermal Hazard? Gas or Vapor Emission? Increase in contact or potential contact?At request of individual
21 Reasons to Downgrade PPE New information - situation less hazardous than originally thoughtChange in conditions that decreases hazardChange in work task that reduces contact with hazardous material
22 PPE Inspection Program inspection and operational testing of equipment from factoryinspection of equipment as it is issued to workersinspection after use or training or prior to maintenance
23 PPE Inspection Program periodic inspection of stored equipmentperiodic inspection when a question arises concerning the appropriateness of selected equipment
24 Other PPE Considerations Maintenance and StorageDonning an ensembleIn-Use MonitoringDoffingClothing reuse
26 PreventionDaily fluid intake must approximately equal the amount of water lost in sweatWhen heavy sweating occurs, encourage the worker to drink moreMaintain water temperature at 50 degrees to 60 degrees FProvide small disposable cups that hold about 4 ounces (0.1 liter)
