4As a respirator user, each year you are required to…. To meet these requirements……….Complete a refresher classComplete this session and testAnd have a successful respirator fit test with the respirator you useContact your EH&S representative to schedule a respirator fit test or check on the EH&SS web site calendar for fit testing times at your facility.
5The respiratory hazards in your workplace should be evaluated by your supervisor…. At the time of hireIf you are a new respirator userBefore you begin working with new or different chemicalsBefore you begin working with the same chemicals under different conditionsIf any of these change, inform your supervisor
6Respiratory Hazard Assessment Table….. Complete for each task, chemical or type of chemicalSubmit it to your EH&S representativeThe Respiratory Hazard Assessment form(and an example of a completed form) can be obtained by contacting your EH&S representative or by downloading the form here
8When evaluating respiratory hazards, your supervisor should also….. Evaluate what type of respiratory protection should be used such asType of respiratorFilter and cartridge neededHow long the filter and cartridges can be usedEvaluate other personal protective equipment neededas wellContact your EH&S representative for respiratoryprotection recommendations
9Before using respirators, always evaluate the possibility of…. Using engineering controls byOpening windows or doorsUsing local exhaust fans or chemical fume hoodsUsing administrative controls bySubstituting less hazardous chemicalReducing exposure time to the chemicalContracting out workWorking outdoors
10Evaluating your health is also important when using a respirator, because… Using a respirator adds stress to the cardiovascular and respiratory system.This added stress could complicate or add to some existing health conditions.Typically when using a respirator, other PPE is also used, creating additional stress on the body.To help evaluate your health risks……..
11A medical questionnaire is required As a new respirator userEvery two years or if directed differently by the physicianWhenever a user’s health changes significantly
12A respirator medical questionnaire Is confidential and only seen by the health care providerIs reviewed by a licensed health care providerIs obtained by contacting your EH&S representative or at the following L&I website:Check out L&I WebsiteSubmit your completed questionnaire in the provided self-addressed return envelope to your EH&S representative
13Selecting a proper respirator ?Important things to remember!EH&S has many makes and models to tryEH&S will assist in selectionIf you are a new user or you already use a respirator and are having problems with it, contact your EH&S representative for assistance
14Selecting a proper respirator MORE important things to remember!Know the contaminants and their concentrations that you are being exposed toIf there isn’t sufficient oxygen present (below 19.5%), supplied air respirators must be usedIf contaminants or their concentrations present Immediately Dangerous to Life and Health (IDLH) conditions, supplied air respirators must be used
15Selecting a proper respirator If contaminants have poor warning properties (taste, smell, irritant), supplied air respirators must be usedIf you have facial hair, or can’t fit any respirator, powered air purifyinghelmet units can be used whenever a negative pressure respirator can beused.
16Selecting filters and cartridges PesticidesCheck the label for recommendationFor most all pesticides the following two are recommended:Dust/mist/fumes filterNo spray oils present: N-95 or P-100 (HEPA)Spray oils present: R-95 or P-100 (HEPA)ToxicsOrganic vapor cartridge (OV), or OV and acid gas cartridge, or multi-contaminant cartridge
17Selecting filters and cartridges Solvents and corrosivesContact your EH&S representative or respirator manufacturerSolvents can have poor warning properties and short breakthrough timesAsbestos and other respirable particles (< 10 um)P-100 (HEPA) filtersNuisance dust, mists, fumesN-95, R-95 (if contain oil), or P-100 filters
18Testing your respirator When first selecting a respirator, finding one that has a good seal and is comfortable is done by trying a variety of respirators and passing a respirator fit test by EH&SSeveral factors can lead to a respirator that does not seal properlyThat is why a respirator fit test is required annually to help insure its fit and to review your use and care of the respirator
19Factors that can change fit Recent dental work, and denturesFacial surgery, treatments, scarsWeight loss or gain of 15 pounds or moreFacial changes from agingImproper storage and maintenance of respiratorRespirator straps losing their elasticity
20A major factor that affects fit FACIAL HAIRA respirator fit test cannot be given if there is facial hair present.A good fit cannot be expected the day you use your respirator when not clean shaven
21When getting a respirator fit test: Be clean shaven in the area of the respirator seal zone that dayBring your respirator
22Using your respirator properly Before you use your respirator, be sure you understand: Inspections (Review Respirator Inspection presentation)Donning and doffing (on and off)MaintenanceChanging cartridges and filtersWhat to do when things go wrong
231. Before you use your respirator… Inspect the respirator to make sure all parts are in place, in good condition, clean, and operableMake sure cartridges and filters are the proper ones for the job and are not damaged and not expiredAfter donning the respirator, do a positive and negative fit check-Demonstration
242.How you put on your respirator is important Placing a half-face first on the bridge of the nose and tightening the upper straps first insures placement for best comfort and prevention from sliding down when perspiringMake sure the straps are adjusted evenly on both sides and the respirator is centered on the face. Using a mirror is helpful for full-face usersAdjusting too tight can result in a poor fit from distortion, discomfort and pain, short use periods due to discomfort, headaches
25How you put on your respirator is important Donning Particulate RespiratorsDonning Dual Cartridge RespiratorsDonning Half-face RespiratorsDonning Full-face Respirators
34When removing your respirator Remove your contaminated gloves firstIf the respirator is contaminated, decontaminate the respirator or put new clean gloves on before removing your respirator
353. Knowing when to change filters and cartridges is very important There must be a written change-out schedule for them in the work area so employees change them out consistentlyVery few cartridges have change-out indicators on them telling you when to change themFor solvents and acids, contact the manufacturer or an EH&S representative
36Changing cartridges and filters For pesticides and toxics change them after eight hours of use.If periods of use are shorter than 8 hours, add cumulative times.If periods in-between use extend 2 weeks or more reduce the eight hour total time.
37Changing filtersN-95 filters – change when breathing becomes more difficult due to resistanceR-95 filters – change after eight hours of use when mists containing oil are presentP-100 – change when breathing becomes more difficult due to resistance
384. Taking good care of your respirator will increase its useful lifetime and insure it works properly…when you need it to.
39Keep a clean respirator Dirt particles under exhalation valves can reduce your seal/fit factorDirt, oils, bacteria, soaps, and disinfectants left on respirators can lead to skin irritation and dermatitis so make sure your respirator is clean and well rinsed before each useIt is recommended to clean after each use
40Clean your respirator properly Clean in warm water(not to exceed 100o F)Use a mild detergentWash with a soft sponge(brush if resistant)Rinse with running (required) warm water (not to exceed 100o F)Sanitize (required) and rinse againRecommend using one-step combination detergent/sanitizer to reduce sanitizer step
41Clean your respirator properly Dry the respirator with a lint free clothOr hang in a clean area until dryPackage it up as soon as it is dry. Do not leave hanging outInspect the respirator after re-assemblyReview the Respirator Inspection presentation
42RepairReplace worn and defective parts with parts ONLY for that specific respiratorDo not use a respirator until all necessary repairs are completedHave readily available the most commonly needed parts for timely repair to insure a working respirator is always used
43It makes a lot of sense to… store your respirator properly It prevents it from getting distorted, which will cause it to lose its ability to fit properly and require it to be replacedIt prevents it from getting damagedIt prevents it from becoming contaminated reducing the protection it can provide
44Good storage means…. Storage in an uncontaminated area Store contaminated cartridges separate from respiratorStore cartridges and respirator in clean sealed containers such as self-sealing bags or sealed plastic containersTo prevent distortion,store in separate hard containers and not in tool boxes or with other items
45Good storage also means… Storage away from heat, sun, and moistureMoisture can reduce the life of some cartridgesLeaving cartridges unsealed can reduce their useful life
47If you experience… Warning signs of taste, smell, irritation, cough Medical symptoms such as difficulty in breathing, shortness of breath, chest pain, over exertionSigns and symptoms of exposure to contaminants
48Get out of area to fresh air and remove respirator
50What to check and do… Inspect respirator Change cartridges or filters When safely in fresh air,What to check and do…Inspect respiratorChange cartridges or filtersRed-don respirator and do positive and negative fit checks to your satisfactionRe-enter and if conditions persist, exit and notify your supervisorAddress medical and exposure symptoms and inform supervisor
51Why is it important to make sure your fit is good, and that you use and maintain the respirator properly?
52and the level of protection you need So that your respirator can provide the level of protection it is designed to give…and the level of protection you need
53If you don’t do these things You operate with a false sense of protection and open yourself to:Chronic exposures you never know aboutAcute exposures that you will know about later- after it’s too late for protection
54Potential hazards you could be exposed to include… Toxics where acute or chronic exposure could result in systemic poisoning, illness, organ disfunction, sensitization,or deathCorrosives (acids), which can cause temporary or permanent tissue damage in the respiratory systemCarcinogens & particulates, which can lead to cancer or other respiratory illnesses respectivelyAllergens that promote illness, allergic reaction, reduced productivity, & sensitization
55Using respiratory protection makes it possible for you to work safely Following your Respiratory Protection Program allows you to work with confidence
