Personal Protective Equipment Train the Trainer WI DPH Regional Offices October 18, 2007 Jim Morrison, CIH, CHMMWI DPH Chm Preparedness Coordinator
Purpose of Training • Inform DPH regional staff of PPE concepts and regulations • Prepare DPH regional staff to conduct respirator training and fit testing • Review administration of DPH PPE programs
PPE Hierarchy of Controls PPE should be a last resort. Try other things first. • Elimination • Substitution • Engineering Controls • Administration • PPE
OSHA PPE Std (29CFR 1910.132) Three basic elements: • Hazard assessment • Select appropriate PPE & assure use • Training
Hazard Assessment Conduct a walk-through survey of the areas in question. Purpose is to identify sources of hazards to workers and co-workers. Consider: • Impact • Penetration • Compression (roll-over) • Light (optical) radiation • Heat • Chemical • Harmful dust These two are key
1. Eyes Airborne dust or particles Liquid chemicals 2. Feet Objects that can strike, crush or puncture feet Chemicals/ Unknown Liquids 3. Hands Materials that might scrape, bruise, or cut Chemicals 4. Head Materials overhead Loud noise 5. Respiratory Dust, mistsVapors 6. BodyParticulateChemicals 7. Other? What hazards might our staff encounter? Talk about the PPE Assessment Form
PPE Categories and Standards • Eye and face Protection (29 CFR1910.133) • Respiratory Protection (29CFR1910.134) • Head Protection (29CFR1910.135) • Foot Protection (29CFR1910.136) • Electrical (29CFR1910.137) • Hand (29CFR1910.138) • Ear (29CFR1910.195)
Eye and Face Protection • ANSI Z87.1-1989 • Protection against impact, dust, splash, radiation • Safety Glasses/sideshields • Goggles • Face shields • Welding
Head and Foot Protection • Many product types/styles are available. They must comply with the following standards: • ANSI Z89.1-1986 Head • ANSI Z41-1991 Foot
Foot Protection • Protection against falling or rolling objects, or objects piercing the sole, and where such employee's feet are exposed to electrical hazards.
Hand Protection • Skin absorption of harmful substances; severe cuts or lacerations; severe abrasions; punctures; chemical burns; thermal burns; and harmful temperature extremes
Compatibility • Importance of knowing contaminant properties (Will your glove protect against anticipated exposures?) • Glove Tragedy • Permeation tables can be found in many safety catalogs. One is Lab Safety Supply
Protective Clothing EPA/OSHA/NIOSH/USCG ensembles: • Level A=+SCBA, fully encaps. Chem. Resistant suit, inner gloves, chem. Resistant boots • Level B=+SCBA, chem. Resist. Clothing, inner/outer gloves, chem. Resistant boots/shoes • Level C=full face APR, otherwise same as B • Level D=coveralls, safety shoes/boots, goggles, hard hat
Hearing Protection • Exposure limit of 90db w/ action level of 85 db (this is very noisy) • Log scale, sound level doubles w/ every 5 db (90dB is twice the level of 85dB) • Hearing Conservation Program required for exposure greater than 85 db, including: • Monitoring • Audiometric Testing • Protective Equipment • Training • Recordkeeping
Respiratory Protection- Respirator Types • Air Purifying. They only cleanse air, do not increase breathable air. They can not be used in confined spaces or where oxygen deficiency is possible. • Cartridges are selected based on physical/chemical properties of contaminants
Respirator Types (cont’d.) • Atmosphere Supplying (add breathable air) • Positive Pressure/Negative Pressure • Half-face/Full face
Protection Factors • Ratio of concentration outside respirator to concentration inside • APRhalf-face= 10 • APRfull-face= 50 • PAPRfull –face= 1,000 • PAPRhood = 25 to 1,000 • SCBApressure= 10,000 • SCBAdemand= 50
Written pgm. Voluntary Use Protection factors Cartridge Change Medical Evaluation Fit Testing Facepiece seal Cleaning & Disinfecting Storage Inspection Evaluation Recordkeeping Respiratory Protection 1910.134 Overview Note: The 3M website has some good training resources.
Voluntary Respirator Use • Staff must be provided Appendix D of the OSHA respiratory protection standard if they wish to wear a respirator where not required • Anything other than a filtering facepiece mask requires medical evaluation • Other respirators require medical eval. and assurance of proper maintenance and use
Cartridge change • Some level of knowledge of exposure level is necessary (Otherwise how do you know your respirator is sufficient?) • Rule of thumb for sanitarian use may be to change after week of use • Be knowledgeable of Maximum Use Concentrations (10x the Permissible Exposure Limit for half-face respirators). From a practical standpoint, if you’re near the PEL, you shouldn’t be there and should ask for professional cleanup response
Medical evaluation • Required because of physiologocal burden of wearing a respirator • Medical questionnaire (DMT-0934) is filled out and reviewed by medical health professional. Typically this is done by a local occupational health provider. If acceptable, the provider writes a statement approving use. • If not, the provider may wish to do an exam. • Questionnaire and exam content are confidential. Employers sees only the physician statement.
Fit Testing • Importance of fit (no facial hair or glasses between mask and skin) • Self Test Protocol • Qualitative Protocol • Repeated annually
Self Fit Check • I. Facepiece Positive and/or Negative Pressure Checks • A. Positive pressure check. Close off the exhalation valve and exhale gently into the facepiece. The face fit is considered satisfactory if a slight positive pressure can be built up inside the facepiece without any evidence of outward leakage of air at the seal. For most respirators this method of leak testing requires the wearer to first remove the exhalation valve cover before closing off the exhalation valve and then carefully replacing it after the test. • B. Negative pressure check. Close off the inlet opening of the canister or cartridge(s) by covering with the palm of the hand(s) or by replacing the filter seal(s), inhale gently so that the facepiece collapses slightly, and hold the breath for ten seconds. The design of the inlet opening of some cartridges cannot be effectively covered with the palm of the hand. The test can be performed by covering the inlet opening of the cartridge with a thin latex or nitrile glove. If the facepiece remains in its slightly collapsed condition and no inward leakage of air is detected, the tightness of the respirator is considered satisfactory.
Qualitative Protocol • Use of a challenge agent (banana oil, bitrex, saccharin) • Selection and donning of respirator. • Multiple exercises/head movements • Jogging in place. • Report if agent detected. • Results documented on DMT-0925
Review Video • Video available from 3M online or video/DVD
DPH PPE Pgm Administration(Draft) • RODs/Pgm Mgrs will do hazard Assessment • PPE needs discussed at PPD • Regional staff will do fit testing and coordinate med evaluations • Central office will do train the trainer and will manage written plans
