Summary

A respirator is any device worn by an individual to remove solid, liquid or gaseous contaminants from breathing air. Respirator use is regulated by the Occupational Safety and Health Administration and is allowed only when feasible engineering controls do not exist or until they can be put into place. University Housing and Dining (UH&D) has established and implemented a respirator program, for both required use and voluntary use respirators. Only employees meeting the authorization requirements of the Respirator Program Administrator can enter work areas requiring respiratory protection The UH&D written respirator program consists of the following  Respirator selection procedures  Medical evaluations  Fit testing procedures for tight-fitting respirators  Procedures for routine and foreseeable emergency situations  Procedures and schedules for maintaining respirators  Staff training on respirators and hazards  Record keeping requirements  Program evaluations  Designation of a program administrator

Purpose

The purpose of this program is to assure that each respirator user is adequately protected from air contaminants of concern under routine and emergency situations; that respirators are kept clean, sanitary, and maintained in good operating condition; and that respirators are used by employees who have been properly fitted and trained.

3.0

Responsibilities

Department Director The director of University Housing and Dining (Director) is solely responsible for this program and has full authority to make necessary decisions to ensure its success. The director has assigned responsibility for implementation and day to day operation of the respirator program to a designated Respirator Program Administrator. Department Respirator Program Administrator The current Respirator Program Administrator is Guy Knepper Occupational Safety Specialist UH&D 4141 Burge Hall The Respirator Program Administrator will work with the Environmental Health & Safety Office (EHS), or equivalent authority, to assess atmospheric hazards and seek consultation at any time there is question regarding hazard determination or appropriate selection and use of respirators. Employees Each Authorized UH&D employee must abide by these program procedures. Authorized employees, while in an area that requires the use of a respirator, shall wear the appropriate properly fitted NIOSH approved respirator. (See Appendix A). Any changes in exposure conditions should be reported to the Department Respirator Program Administrator. Environmental Health & Safety Office (EHS) The EHS Office will work with the department to conduct hazard assessments, set up the initial program, provide consultation as needed, and periodically evaluate compliance and effectiveness of the department program.

Selection Procedures

Survey University Housing and Dining work areas are surveyed for respiratory hazards with the help of EHS or other authorities on respiratory hazards. The department will arrange for additional surveying and sampling as needed or required to update air contaminant hazard information if exposure conditions change. Data collected during the survey and used in determining the need for respiratory protection includes:  Types of respiratory hazards  Nature of contaminants  Concentration of respiratory hazards  Established PEL's -TWA, STEL, and C (PEL = Permissible Exposure Limit; TWA = Time Weighted Average; STEL = Short Term Exposure Limit; C = Ceiling.)  Determination of acceptable airborne concentration for contaminants without established PEL's  Length of worker exposure times  Additive exposure effects from synergistic contaminants  Health signs and symptoms being experienced by workers Selection Criteria Where survey data indicates the need for respiratory protection, the department provides the employee an appropriate respirator model with acceptable fit at no cost. Respirator selection is based on hazards the staff member is exposed to, and use factors affecting performance and reliability. Only NIOSH certified respirators are used. Respirators are assigned to employees for their exclusive use. If the concentration for a hazardous air contaminant has not been determined for an area, do not enter it. Selection and use of respirators for department employees includes consideration of the following:  Estimate of exposure hazard  Chemical and physical form of contaminant  Characteristics of the hazardous operations or processes  Location of hazardous areas  Period of time which respiratory protection may be needed  Activity of workers in the hazardous areas  Physical characteristics, capabilities, and limitations of various types of respirators  Respirator protection factors and respirator fit Limitations of Use Department employees are only allowed to wear the air purifying respirators they are fitted for. Department employees cannot perform work in other departments requiring a respirator unless EHS or another authority on respiratory hazards has completed a hazard survey and their respirators are found to be adequate. Air purifying respirators shall not be used under the following conditions:  Immediately Dangerous to Life and Health (IDLH) atmospheres.  Oxygen deficient atmospheres (less than 19.5% oxygen).  Situations where contaminants lack sufficient warning properties.  Atmospheres containing unknown contaminants or concentrations.  Atmospheres containing contaminant concentrations exceeding maximum use concentration of the respirator or cartridge.

Only self-contained breathing apparatus (SCBA) or airline respirators with an emergency escape supply shall be used to enter areas with unknown hazardous air contaminant concentration or in IDLH situations. Use Approval UH&D employees must complete all requirements of the respirator program before using a respirator. All employees required to wear a respirator must have an initial medical evaluation. Subsequent yearly evaluations require completion of a medical questionnaire presented in person for review by the UEHC staff. Medical examination may be optional if UEHC staff’s review of the questionnaire determines an exam is not required. The authorization tables in Appendix A list employee names, the type of respirator, and the location or operation where respirator use is required. Only authorized employees may use a respirator. Voluntary Respiratory Use UH&D employees may voluntarily use a respirator for those tasks listed in Appendix A1, List of Employees Authorized for Voluntary Respirator Use, as not requiring respirator use provided they obtain approval from the Respirator Program Administrator.  If the employee wants to use a disposable dust mask respirator, then it must be documented that the employee has read Appendix D (Information for Employees Using Respirator When Not Required under the Standard) of 29 CFR 1910.134. Voluntary use of a disposable dust mask respirator does not require an annual medical examination.  If a dust mask respirator is not wanted, then the employee will use the air purifying half face mask respirator already assigned to them and will keep it clean, stored properly, and maintained to prevent dermatitis or other skin hazards.  Any respirator may be used as a, voluntary use respirator, provided it does not create a health or safety risk. An initial medical evaluation is required only if the device has an elastomeric (rubber or silicone) tight-fitting face piece.  Fit testing is not required for voluntary use respirators because respirator use is not necessary.

5.0

Medical Evaluation

Prior to initial use, medical evaluations shall be provided to UH&D employees required to use a respirator and in cases in which a voluntary-use respirator has an elastomeric tight-fitting face piece. The University Employee Health Clinic (UEHC) will provide medical evaluations which will consist of completing a questionnaire or seeing the HCP (Health Care Provider), or both, at the discretion of the HCP. Employees scheduled to go to UEHC will need to fill out the OSHA required Respirator Fitness Questionnaire and bring it with them to their appointment. Additional medical evaluations are required under any of the following circumstances:     

If an employee reports medical signs or symptoms related to the ability to use a respirator; If the physician or other licensed healthcare provider, program administrator, supervisor recommends reevaluation; If the information from the respirator program, including observations made during fit testing and program evaluation indicates a need for employee reevaluation; or If a change occurs in workplace conditions (e.g., physical work effort, protective clothing, or temperature) that may substantially increase the physiological burden placed on an employee. Individual departments may (based on the hazards to which employee exposed) request that certain staff undergo medical clearance for respirator use and also undergo a baseline only or yearly medical examination by UEHC.

Student help employed for less than 90 days will have their respirator medical evaluation performed by Student Health Service.

6.0

Fit Testing

All UH&D employees required to use a tight-fitting facepiece respirator will be fit tested with the same make, model, style and size respirator they will use. Fit testing protocols and procedures are in the most recent version of Appendix A of OSHA’s 29 CFR 1910.134 respirator regulations. Fit testing will be performed before initial use of a respirator, at least annually thereafter, and whenever conditions (such as employee's physical condition) change that could affect respirator fit. Respirators are fit tested using a QLFT, or a PortaCount 8010 QNFT method. Respirators modified for fit testing shall be returned to the NIOSH-approved configuration before using the respirator in the workplace. Fit testing requires the respirator user to handle the respirator, have it fitted properly, test the facepiece-to-face seal, and to wear it in normal air for a familiarity period.

7.0

Routine and Emergency Situation Procedures

Respirators shall be put on before entering a work area with a hazardous atmosphere. Employees wearing tight-fitting respirators shall perform a successful user seal check using procedures from Appendix B-1 of OSHA's 29 CFR 1910.134 each time they put on the respirator. The respirator shall not be removed while in the hazardous atmosphere. Employees are not permitted to enter IDLH atmospheres, unknown hazardous atmospheres, or any hazardous atmosphere that exceeds the capability of their assigned respirators. Respirators are not worn when conditions prevent a good facepiece to face seal or interfere with valve function. Such conditions may be a growth of beard, sideburns, a skull cap that projects under the facepiece, temple pieces on glasses, goggles or other personal protective equipment, or the absence of one or both dentures. Employees wearing respirators in hazardous atmospheres must leave the required respirator use area:  To wash face and respirator facepiece as necessary to prevent eye or skin irritation from use.  If they detect vapor or gas breakthrough, changes in breathing resistance, or leakage of the facepiece.  To replace the respirator or filter, cartridge, or canister elements. When a respirator user in a hazardous atmosphere detects vapor or gas breakthrough, breathing resistance changes, or facepiece leakage, the department must replace or repair the respirator before the employee returns to the work area. If during respirator use a change occurs in work conditions that could result in higher air contaminant levels, the employee will leave the contaminated area until the air contaminant concentration can be determined and the correct respirator provided. If during use the respirator fails or the air contaminant(s) is detected by the respirator user, he/she will leave the area immediately and not return until the respirator problem is corrected.

8.0

Maintenance Procedures and Schedules

The department has a respirator maintenance program to assure each respirator wearer has a clean, sanitary, functioning respirator. Respirators will be regularly cleaned, disinfected, inspected, repaired, stored, and when necessary, discarded.

Cleaning and Disinfecting Respirators will be cleaned and sanitized using procedures from Appendix C, which follows protocol of Appendix B-2 of OSHA's 29 CFR 1910.134 regulations. Respirators are issued for the exclusive use of each staff member so they will be cleaned and disinfected by the user as often as necessary to keep it sanitary. Respirators used routinely will be inspected during cleaning and worn or deteriorated parts will be replaced. Inspection The department will ensure routine use respirators are inspected before each use and after cleaning, checking respirator function, tightness of connections, condition of parts (including facepiece, head straps, valves, filtering elements), and for any deterioration or loss of pliability of elastomeric (e.g., rubber or silicone) parts. Respirator Repairs Respirators failing inspection or found defective are removed from service. Adjust, repair, or discard respirators using the following procedures:  Respirator repairs or adjustments are only done by properly trained personnel using parts designed for the respirator according to manufacturer's recommendations.  Discard respirators permanently removed from service so they do not return to service. Storage All respirators are to be stored in a clean and sanitary location to protect them from damage, contamination, dust, sunlight, extreme temperatures, excessive moisture, damaging chemicals, and to prevent facepiece and exhalation valve deformation.

9.0

Training Procedures

UH&D department respirator users are provided effective, comprehensive, understandable training in proper use and limitations of each specific respirator type assigned. Training is required prior to use in workplace, annually, and more frequently if necessary to ensure safe respirator use. For air-purifying respirators, training is done by a qualified person. Training for air-purifying respirators is outlined in Appendix B and explains:  Respirator necessity and how improper fit, usage, or maintenance can compromise respirator protection.  Limits and capabilities of respirator.  Effective respirator use in routine and emergency situations, including malfunctions.  How to inspect, put on, remove, use, and perform check seals with the respirator.  Procedures for respirator maintenance and storage.  Medical signs and symptoms that may limit or prevent effective use of respirators.  General requirements of respirator usage. Department employees are provided an opportunity to handle each respirator, have it fitted properly, test the facepiece-to-face seal, and wear it in normal air for a familiarity period.

10.0

Record Keeping Requirements

All records listed below will be kept for the duration of employment of the affected staff members plus at least one year (30 years recommended). UEHC will maintain medical evaluation records and make them available per 29 CFR 1910.1020. The Respirator Program Administrator will maintain the following records:



  

11.0

Records of employee respirator fit testing including: name or identification of employee tested; type of fit test performed; specific make, model, style, and size of respirator tested; date of test; and the pass/fail results for QLFTs or the fit factor and strip chart recording or other recording of test results for QNFTs. A current list of staff members trained and medically approved for respirator use. Employee training records (course content, attendance sheets, and tests). Inspection and evaluation records of program effectiveness. A written copy of current respirator program.

Program Evaluations

The Program Administrator maintains appropriate surveillance of work area conditions and staff member exposure. He/she monitors the effectiveness of the program by making unscheduled observations of where respirators are used to confirm proper respirator use, and by discussing specific aspects of the respirator program with personnel during appropriate scheduled meetings. Factors to assess include, but are not limited to:  Respirator fit (including ability to perform work effectively).  Appropriate respirator for hazards exposure.  Proper respirator use under workplace conditions employee encounters.  Proper respirator maintenance. Problems identified during surveillance are corrected. Any change in a work condition with potential to increase staff member exposure will result in a review of hazards to determine if respirator program modification is necessary.

If any leakage is detected, readjust straps and repeat test until no leakage occurs. 8. Perform negative user seal check by placing the palms of the hands over the cartridges and gently inhaling. A slight negative pressure should build up inside respirator. If any leakage is detected, readjust straps and repeat test until no leakage occurs.

Removing Respirator: 1. Unhook neck straps. 2. Pull head cradle up and over the head.

Cleaning and Sanitizing Respirator users must clean their respirator after use with respirator wipes, or clean it more completely using the following procedure: 1. Remove cartridges/filters. Dispose of expired cartridges/filters; do not wash or disinfect used cartridges. 2. Disassemble respirator, including valves, facepiece yoke, and cartridge holders. 3. Clean respirator parts: a. immerse them in warm soap and water solution or commercial cleaner/sanitizer; b. gently scrub facepiece and parts with a cloth or a stiff bristle (not wire) brush; c. remove foreign matter from surfaces of exhalation valve and seats; and d. rinse parts thoroughly in clean, warm, preferably running water. Drain. 4. If cleaner does not contain a sanitizer, then sanitize parts by immersing for two minutes in a water solution containing: a. commercial cleaner/sanitizer, or b. two tablespoons of bleach per gallon of water, or one teaspoon of tincture of iodine per gallon of water. 5. Thoroughly rinse parts with warm water. 6. Allow parts to air-dry in a clean location. 7. Reassemble respirator by reversing steps used to disassemble. Install new cartridges if needed.

Respirator Repairs Respirators failing inspection or found defective are removed from service. Adjust, repair, or discarded respirators using the following procedures: 1. Reassemble respirator by reversing steps used to disassemble. Install new cartridges if needed. 2. Respirator repairs or adjustments only done by properly trained personnel using NIOSH-approved parts designed for the respirator, according to manufacturer’s recommendations. 3. Discard respirators permanently removed from service so they do not return to service.

Respirator Storage 1. Store respirators in a clean sealed container while not in use. Clean nylon gym bags are acceptable. 2. Stored in a clean dry place. Do not distort rubber facepiece during storage.

Evaluator _________________________________

Checked with employees to determine if they have had any problems with their respirators and corrected any problems discovered. Written respirator program and employee field use of respirators match and are based on the most recent respirator rules and employee respirator use procedures. Any significant change in workplace conditions has been evaluated and the respirators and procedures in use are correct for the airborne hazards in the workplace. Respirators are proper ones for hazardous contaminants under work conditions the employees encounter. Each employee required to wear a respirator has had a medical evaluation within the last year. Each employee required to wear a respirator has passed a fit test on each model, type, and style of respirator he/she wears within the last year. The respirator(s) assigned to each employee does pass user seal checks and is being worn correctly. Employees assigned a respirator(s) are inspecting them before use and performing user seal checks when the respirator is first put on. Respirators are being properly inspected, are cleaned/sanitized routinely using procedures in Appendix E, and are repaired as needed. Each respirator is being storage in a clean, safe manner where the facepiece will not become distorted. Filters/cartridges/canisters remain properly labeled. All employees required to use respirators have received initial respirator training and have had respirator training at least within the last year. Training, fit test, medical evaluation and program evaluation records are current. Copies of written program and respirator rules are available for employee review. For an item that is not satisfactory note corrective action taken to resolve.

Information for Employees Using Respirator When Not Required Under Standard All employees authorized to use a voluntary respirator are required by OSHA to read Appendix D below. Appendix D to Section 1910.134 (Mandatory) Information for Employees Using Respirators When Not Required Under the Standard Respirators are an effective method of protection against designated hazards when properly selected and worn. Respirator use is encouraged, even when exposures are below the exposure limit, to provide an additional level of comfort and protection for workers. However, if a respirator is used improperly or not kept clean, the respirator itself can become a hazard to the worker. Sometimes, workers may wear respirators to avoid exposures to hazards, even if the amount of hazardous substance does not exceed the limits set by OSHA standards. If your employer provides respirators for your voluntary use, of if you provide your own respirator, you need to take certain precautions to be sure that the respirator itself does not present a hazard. You should do the following: 1. Read and heed all instructions provided by the manufacturer on use, maintenance, cleaning and care, and warnings regarding the respirators limitations. 2. Choose respirators certified for use to protect against the contaminant of concern. NIOSH, the National Institute for Occupational Safety and Health of the U. S. Department of Health and Human Services, certifies respirators. A label or statement of certification should appear on the respirator or respirator packaging. It will tell you what the respirator is designed for and how much it will protect you. 3. Do not wear your respirator into atmospheres containing contaminants for which your respirator is not designed to protect against. For example, a respirator designed to filter dust particles will not protect you against gases, vapors, or very small solid particles of fumes or smoke. 4. Keep track of your respirator so that you do not mistakenly use someone else's respirator. ___________________________________________________________________________ Employee Verification: By signing this record, I indicate I have read the above information. I understand that any voluntary use respirator provided to me by the department, or that I bring into the workplace, can not be used where respirator use is required because of hazardous air contaminant concentrations. I also understand that filtering facepiece respirators (disposable dust masks) should be discarded when necessary and replaced with a new respirator.
