1 1 PPE: Clothing/Ensembles Instructional Goal: The participant will recognize the purpose of personal protective equipment and personal protective clothing.

2 2 PPE: Clothing/Ensembles Shield or isolate individuals from waste site hazards Shield or isolate individuals from waste site hazards Careful selection and use of adequate PPE Careful selection and use of adequate PPE No single combination of equipment and clothing is capable of protecting against all hazards No single combination of equipment and clothing is capable of protecting against all hazards

3 3 Developing a PPE Program Hazard identification Hazard identification Medical monitoring Medical monitoring Environmental surveillance Environmental surveillance Selection, use, maintenance, and decontamination of PPE Selection, use, maintenance, and decontamination of PPE

4 4 Developing a PPE Program Training Training Program review and evaluation Program review and evaluation Protective clothing Protective clothing

5 5 Selection of Chemical Protective Clothing

6 6 Permeation and Degradation Permeation Permeation Degradation Degradation Penetration Penetration

7 7 Permeation Rate Clothing material Clothing material Manufacturing method Manufacturing method Concentration of hazardous material Concentration of hazardous material Temperature, pressure and humidity Temperature, pressure and humidity Solubility of the chemical through the clothing material Solubility of the chemical through the clothing material

8 8 Heat Transfer Characteristics clo value is thermal insulation value of the material clo value is thermal insulation value of the material

9 9 Work Mission Duration Air supply consumption Air supply consumption work rate work rate fitness fitness body size body size breathing patterns breathing patterns

10 10 Work Mission Duration Ambient temperature - hot and cold temperatures affect Ambient temperature - hot and cold temperatures affect u valve operation u durability and flexibility of suit materials u integrity of suit fasteners u permeation rate of chemicals u concentration of airborne contaminants

11 11 Work Mission Duration Permeation and penetration by chemical contaminants into the material of a Suit/Ensemble Permeation and penetration by chemical contaminants into the material of a Suit/Ensemble Coolant supply Coolant supply

12 12 Selection Summary Durability Durability Will the material resist tears, puncture and abrasions? Will the material resist tears, puncture and abrasions? Will the material withstand repeated use after contamination/decontamination? Flexibility Flexibility Will the CPC interfere with a worker's ability to perform his or her assigned tasks? (This is particularly important to consider for gloves.) Temperature effects Temperature effects Will the material maintain its protective integrity and flexibility under the extremes of heat and cold?

13 13 Selection Summary Ease of decontamination Ease of decontamination Are decontamination procedures available on site? Will the material pose any decontamination problems? Should disposable clothing be used? Compatibility with other equipment Compatibility with other equipment Does 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 use Duration of use Can the required task be accomplished before contaminant breakthrough occurs, or before degradation of the CPC becomes significant?

14 14 Special Conditions fire fire explosion explosion radiation radiation

15 15 Personal Protective Equipment Levels of Protection - Maximum skin and respiratory protection Level A - Maximum skin and respiratory protection - Maximum respiratory with some skin protection Level B - Maximum respiratory with some skin protection - Limited level of respiratory protection and skin protection from airborne hazards Level C - Limited level of respiratory protection and skin protection from airborne hazards - No respiratory protection and limited skin protection from airborne hazards Level D - No respiratory protection and limited skin protection from airborne hazards

16 16 Level A Level A fully-encapsulating fully-encapsulating maximum skin and respiratory protection maximum skin and respiratory protection Personal Protective Equipment Levels of Protection NOTE: 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 17 Level B Level B maximum respiratory protection maximum respiratory protection some skin protection some skin protection Personal Protective Equipment Levels of Protection NOTE: This is the minimum level recommended for initial site entries until the hazards have been further identified.

18 18 Level C Level C limited level of respiratory protection limited level of respiratory protection skin protection from airborne hazards skin protection from airborne hazards Personal Protective Equipment Levels of Protection NOTE: 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 19 Level D Level D no respiratory protection no respiratory protection limited skin protection from airborne hazards limited skin protection from airborne hazards Personal Protective Equipment Levels of Protection NOTE: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 20 Reasons to Upgrade PPE Dermal Hazard? Dermal Hazard? Gas or Vapor Emission? Gas or Vapor Emission? Increase in contact or potential contact? Increase in contact or potential contact? At request of individual At request of individual

21 21 Reasons to Downgrade PPE New information - situation less hazardous than originally thought New information - situation less hazardous than originally thought Change in conditions that decreases hazard Change in conditions that decreases hazard Change in work task that reduces contact with hazardous material Change in work task that reduces contact with hazardous material

22 22 PPE Inspection Program inspection and operational testing of equipment from factory inspection and operational testing of equipment from factory inspection of equipment as it is issued to workers inspection of equipment as it is issued to workers inspection after use or training or prior to maintenance inspection after use or training or prior to maintenance

23 23 PPE Inspection Program periodic inspection of stored equipment periodic inspection of stored equipment periodic inspection when a question arises concerning the appropriateness of selected equipment periodic inspection when a question arises concerning the appropriateness of selected equipment

24 24 Other PPE Considerations Maintenance and Storage Maintenance and Storage Donning an ensemble Donning an ensemble In-Use Monitoring In-Use Monitoring Doffing Doffing Clothing reuse Clothing reuse

25 25 Heat Stress

26 26 Prevention Daily fluid intake must approximately equal the amount of water lost in sweat Daily fluid intake must approximately equal the amount of water lost in sweat When heavy sweating occurs, encourage the worker to drink more When heavy sweating occurs, encourage the worker to drink more Maintain water temperature at 50 degrees to 60 degrees F Maintain water temperature at 50 degrees to 60 degrees F Provide small disposable cups that hold about 4 ounces (0.1 liter) Provide small disposable cups that hold about 4 ounces (0.1 liter)

27 27 Monitoring heart rate heart rate oral temperature oral temperature body water loss (weight change) body water loss (weight change)

28 28 Temperature Normal Sweating Muscle slow down Loss of ability for self help Possible Death

29 29 Heat Rash - tiny raised blister-like rash Heat Rash - tiny raised blister-like rash u keep area dry and cool Heat Cramps - muscular pain and spasms Heat Cramps - muscular pain and spasms u replacement of salt through liquids Heat Exhaustion - headache, nausea, dizziness, vomiting, and heavy sweating Heat Exhaustion - headache, nausea, dizziness, vomiting, and heavy sweating u move to cooler environment and elevate feet Heat Stroke - very small pupils, confusion, unconsciousness and very high body temperature Heat Stroke - very small pupils, confusion, unconsciousness and very high body temperature u summon medical help immediately Symptoms and Treatment
