If a fit cannt be established using a quantitative fit test, then ther ptins fr respiratry prtectin may be discussed with the department. Emplyee must verify understanding f limitatins and demnstrate cmpetency f respiratr use, care and maintenance; Fit testers shall fllw the requirements f the prgram and CSA fit testing standard (Z ) and shall nt perfrm a fit test if they bserve that the persn is nt free frm interference where the respiratr seals t the skin f the face r neck; Recrds f testing are printed and reviewed with the emplyee; Recrds are signed by tester and emplyee (emplyee signature nt required n qualitative fit test recrd) and a cpy is prvided t the supervisr; Recrds will be stred in Medgate; Emplyee returns fr recall: in tw years if there is a physical change t the face that wuld warrant re-testing if a different type f mask is required based n a change in ptential respiratry hazards (e.g. a new hazardus cntaminant is encuntered and requires increased prtectin factr) Respnsibility fr recalls is shared by the emplyee, supervisr, and Staff Wellness. 6.0 Use f Respiratrs Respiratr use is based n the CSA standard Z Selectin, use and care f respiratrs. 6.1 User requirements Befre being assigned any task that requires the use f a respiratr, the user shall meet all the health screening, training, and fit testing requirements in this prgram. 6.2 Tight-fitting respiratr seal with skin Respiratrs requiring a tight fit in rder t perfrm effectively shall nt be wrn when an effective seal t the face r neck f the persn cannt be achieved and maintained. T prmte the safety f persns using tight-fitting respiratrs, the seal t the face r neck shall be effectively maintained in accrdance with the requirements f the Respiratr Interference Cncerns sectin f this prgram dcument (Appendix C) thrughut the perid during which respiratr use is required. If during the curse f wrk, a persn develps any cnditin that degrades the respiratr seal t the face r neck, the persn shall restre the required interference-free cnditin in a nnhazardus envirnment. Date Revised: Revisin 2 Page 9 f 25

10 6.3 Respiratr interference cncerns Wrkers and supervisrs shall ensure that ptential interferences t the fit and functin f the respiratr are effectively managed accrding t the requirements described belw. Individuals wh are unwilling r therwise unable t cmply with the interference-free requirement, r wh are unable t btain an acceptable fit, shall be prhibited frm using a tight-fitting respiratr Facial Hair Individuals shall present themselves fr fit testing free frm interference f hair with the respiratr functin, valves r where the respiratr seals t the skin f the face r neck. The rate f hair grwth varies, fr many this requires being clean-shaven within the previus 24 r preferably 12 h t ensure that hair neither infringes n the sealing surface f the respiratr nr interferes with valve r respiratr functin. See Appendix C fr examples f acceptable and unacceptable facial hair grwth Persnal cnditins Individuals shall present themselves fr fit testing in the same persnal cnditin they wuld expect t be in when using the respiratr. This includes hair styles (e.g., hair buns) and wearing r nt wearing dentures, eyeglasses, r cntact lenses. The use f cntact lenses may be apprved by the Occupatinal Health Nurse after cnsideratin f thse factrs inside and utside the tight-fitting respiratr that culd affect the eyes f the user Persnal effects r accessries Individuals shall present themselves fr fit testing in such a way that persnal accessries such as head cverings, garments, facial jewelry, r ther items shall nt cme between the skin and the sealing surface f the respiratr. Nte: Such accessries can impair respiratr effectiveness by interfering with valve functin, respiratr adjustability, and prper secure psitining. Makeup, creams, r ltins can als interfere with effective respiratr functin PPE integratin When PPE such as eye, face, head, r hearing prtectrs r prtective garments are required t be wrn during respiratr use, they shall be wrn during respiratr fit testing t ensure that the respiratr seal is nt cmprmised. 6.4 User seal check f face-t-facepiece seal The user f a respiratr shall check the seal f the face-piece immediately after dnning the respiratr in accrdance with nline training and fit testing instructins. A user seal check shall nt be used as a substitute fr a qualitative r quantitative fit test. 6.5 Cmmunicatins when using a respiratr The respiratr face-t-facepiece seal shall nt be brken t cmmunicate. Date Revised: Revisin 2 Page 10 f 25

11 Nte: Verbal cmmunicatin while using a respiratr is ften necessary t perfrm specific tasks; hwever, mvement f facial features while talking can adversely affect the seal f the face-piece. The use f varius types f mechanical and electrnic speech transmissin devices can minimize the pssibility f face-piece leakage when the user is speaking. Respiratrs fr use in a hazardus atmsphere that requires intrinsic safety and that are equipped with electrnic speech transmissin devices having an electrical pwer supply shall be intrinsically safe. Nte: In extremely cld weather, battery pwer can be unreliable. 6.6 Change-ut prcedures, schedules and service time A qualified persn shall establish a change-ut schedule fr the replacement f air-purifying filters r cartridges f respiratrs befre their useful service life is ended. Warning prperties f the cntaminant shall nt be relied n fr cartridge/canister change-ut, shuld wrkers detect dur, experience resistance when drawing breath, r experience any irritatin symptms f the cntaminant befre the end f the change-ut schedule, Staff Wellness shall be infrmed and shall re-evaluate this respiratr use, i.e., the change-ut schedule, the wrkplace cncentratins, r ther cnditins f use [relative humidity (RH), wrk rate, etc.]. Nte: Respiratr cartridge change-ut can include end-f-service-life indicatrs, maximum use time, and breathing resistance as apprpriate. The useful service life f a gas/vapur cartridge r canister r a particulate filter is affected by several factrs, including: a) The cntaminant s chemical prperties, physical state, and cncentratin; b) The envirnment, temperature, humidity, and atmspheric pressure; c) The physical/chemical characteristics f the air-purifying element; surface area, vlume; d) The mechanism used t remve the cntaminant; filtratin, electrstatic charge, and absrptin r adsrptin; e) The effectiveness f the air-purifying element against the cntaminants; f) The breathing rate and vlume f the respiratr user; g) The pattern f use, whether cntinuus r intermittent.

D-5.1 Strage f cylinders nt in current use Date Revised: Revisin 2 Page 23 f 25

24 Cylinders nt in current use and thse in lng-term strage shuld be stred at reduced pressure in the vertical psitin (valve up) and never inverted. Ntes: The reductin in pressure is imprtant because crrsin attack is reduced in decreasedxygen partial pressures. Vertical strage reduces the extent f crrsin by minimizing the interface between metal and water Because steel cylinders are mre prne t crrsin activity, vertical strage f them at reduced pressure is especially imprtant. Whenever pssible, cylinders shuld be stred indrs in a warm, dry envirnment. Unpressurized cylinders shuld be stred with the main valve clsed. D-5.2 Rtatin f cylinders in current use Cylinders shuld be numbered, clur-cded, r arranged in a manner that ensures that all f them are used n a regular basis. Nte: Prtective caps shuld be used t prevent physical damage t the cylinder valve threads and prevent dirt and misture frm entering the valve bdy. Prir t using an SCBA cylinder that has nt been used in any 12-mnth perid, the air shall be discarded by slwly depressurizing the cylinder t the atmsphere and refilling it with cmpressed breathing air meeting the requirements f CSA Z D-6.0 SCBA Cylinder Testing, Filling, Marking and Maintenance At the University f Calgary, cylinders shall be filled, marked, and maintained by a qualified individual in accrdance with manufacturer s recmmendatins and CSA B339 standards.
