An effective installation Respiratory Protection Program requires close liaison among Army personnel; supervisors; local labor organizations, where applicable; the installation respirator specialist; the IRPD; the SOH manager; and the medical commander to safeguard life and health through the proper selection, use, care, and maintenance of respirators. The elements in this chapter will be followed to establish an effective Respiratory Protection Program.
a. The IRPD, in coordination with the SOH manager and the medical commander, will prepare a local implementing regulation that prescribes the installation Respiratory Protection Program. This regulation will include all information and guidance necessary for proper respirator selection, use, care, and maintenance.
b. Written job site SOPs will —
(1) Be prepared by supervisory personnel with guidance from the designated SOH manager and the medical commander and approved by the IRPD for each job site using respirators.
(2) Describe the safe use of respirators in dangerous atmospheres that might be encountered in normal operations or in emergencies.
a. Respirators shall be selected on the basis of the potential workplace exposure hazard, respirator design criteria, and user-specific factors such as comfort and fit.
b. No single manufacturer's make, model, and size respirator will fit all users; therefore, a sufficient number of models and sizes will be made available to accommodate all respirator users.
c. Detailed selection criteria, including selecting respirators for use in IDLH atmospheres, are contained in Department of Health and Human Services (DHHS) NIOSH Publication No. 2005-100. Consult the U.S. Army Public Health Command for additional guidance such as emerging issues (for example, nano-particules) and respiratory protection.
d. All full-face respirator lenses used by Army personnel must meet the requirements for "high impact" classification, optical, and markings of the American National Standards Institute's standards in ANSI Z87.1.
a. Only respirators approved by NIOSH can be used. Military masks used in military-unique chemical agent workplaces by Army personnel are exempt from the requirement to procure "only respirators approved by NIOSH" and are specifically prescribed in DA Pam 385-61 .
b. Respiratory protection will be provided to Army civilian employees, whether required or voluntary users, at no cost to the employee. The installation or activity will use appropriated fund accounts to purchase RPE. Nonappropriated fund activities will use their own funds, unless authorized for appropriated fund sources or unless funds are provided for by a host-tenant agreement.
c. Authorization and guidance for issuing RPE to military personnel appear in the common tables of allowance (CTA) 8-100, CTA 50-900, CTA 50-909, and CTA 50-970.
d. Tight-fitting respirators will not be worn by personnel who have conditions that could interfere with the face-to-facepiece seal or valve function. These conditions include, but are not limited to, facial hair, deep scars, facial jewelry, and missing dentures.
e. The use of corrective lenses including contact lenses and spectacles are permitted for those who are required to use full-face respirators in their jobs provided they do not interfere with the seal of the respirator. Full-face respirators require corrective lens insert kits.
f. Contact lens use poses additional hazards in chemical environments and should be preceded by a risk assessment and approved by the IRPD. Contact lenses should not be worn under respirators in areas of potential hazard from chemical splash. Contact lenses will not be worn during basic training, field exercises, gas chamber exercises, deployments, or combat. Exception: Contact lenses may be worn in field exercises, deployments, or combat for certain duties or evaluation programs approved by the Office of The Surgeon General.
g. Supervisors will establish procedures for the following operational environments, in coordination with the medical commander and the SOH manager:
(1) Areas that may be IDLH environments and/or confined spaces.
(2) Interior structural firefighting environments.
h. All personnel who choose to use a government issued respirator when one is not required (voluntary) will be included in the installation's Respiratory Protection Program. Note: All aspects of the program including medical evaluation, training, fit testing, and recordkeeping will apply to voluntary users. The OSHA standard has less stringent requirements for voluntary users. Therefore, appendix D of 29 CFR 1910.134 will not be applicable.
a. Using a respirator may place a physiological burden on Army personnel that varies with the type of respirator worn, the conditions under which the respirator is used, and the medical condition of the employee. Army personnel who are required to wear respirators in the workplace must be physically able to safely perform their jobs while wearing protective equipment.
b. A medical evaluation will be performed to determine the employee's ability to use a respirator. The evaluation will be performed using the medical questionnaire in 29 CFR 1910.134, appendix C. The evaluation will be completed before respirators are used by the employee.
c. The medical evaluation will be performed prior to first-time use and a reevaluation will take place annually or when —
(1) An employee reports medical signs and symptoms that are related to the ability to use a respirator.
(2) A physician or other licensed healthcare professional, supervisor, or IRPD informs the medical commander that the employee needs to be reevaluated.
(3) Information from the Respiratory Protection Program, including observations made during fit testing and program evaluation, indicate a need for employee reevaluation.
(4) A change occurs in workplace conditions that may result in a substantial increase in the physiological burden placed on the employee.
a. Training will be provided by the installation respirator specialist or other person appointed by the senior commander or state and territory adjutant general.
b. Training will provide individuals with an opportunity to handle the respirator, have it fitted properly, test its facepiece-to-face seal, wear it in normal air for an acclimatization period, and finally wear it in a test atmosphere (during fit testing). The training will be conducted in a manner that ensures it is understood by those personnel receiving the training. Minimum training will include —
(1) Why the respirator is necessary and the consequences of improper fit, use, or maintenance.
(2) The capabilities and limitations of the respirator, including air purifying cartridges/canisters/filters, service life, change out schedules, and any compressed air sources. Consult ANSI Z88.7 for respirator cartridge, canister, and filter color coding system information.
(3) How to use the respirator in an emergency including respirator malfunction.
(4) How to inspect, put on, check the seals for leaks, and remove.
(5) Maintenance, shelf life, and storage.
(6) How to recognize medical signs and symptoms that may limit or prevent the effective use of respirators.
(7) The general requirements of the Respiratory Protection Program.
c. The training will be given prior to the respirator being used in the workplace and at least annually thereafter.
Fit testing will be conducted by the installation respirator specialist or other person appointed by the installation commander or state or territory adjutant general.
a. All Army personnel required to wear a respirator with a negative or positive pressure tight-fitting facepiece must be fit tested with the same make, model style, and size respirator they will use in the workplace.
b. Before initial use, after any model change, and at least annually, fit tests will be administered using qualitative or quantitative fit testing protocols outlined in appendix A of 29 CFR 1910.134. Additional fit testing will be conducted when changes occur in the physical condition of the employee that may affect the face seal, such as weight loss, facial scarring, dental changes, or cosmetic surgery. Consult ANSI Z88.10 for additional guidance on fit testing.
c. Local procurement of respirators is authorized to obtain a respirator with an acceptable fit.
a. The respirator user is responsible for the primary maintenance and cleaning of the respirator unless a centralized maintenance and cleaning facility exists. Where respirators are used collectively or kept ready for emergency use by a shop or operating activity, the commander or supervisor of the activity will ensure maintenance and cleaning per manufacturer's instructions.
b. Procedures for maintenance and care of respirators will be established. At a minimum, procedures will cover —
(1) Cleaning and disinfecting.
(2) Proper storage.
(3) Regular inspections for defects (including leak check).
c. Replacement or repair of respirators will be done by the installation respirator specialist or other qualified individuals using parts designed for the respirators. No attempt will be made to replace components or to make adjustments or repairs beyond the manufacturer's recommendations.
d. Disposal will be done only by the installation respirator specialist.
A program evaluation must include an annual written program review, a workplace evaluation, and consultations with respirator users to ensure the Respiratory Protection Program is being properly implemented and respiratory protection is being used correctly. This responsibility will be shared by the IRPD and SOH manager unless otherwise specified by the medical commander.
a. Breathing air for respirators may be supplied from cylinders or air compressors. The requirements for Grade D breathing air will be met as defined in Compressed Gas Association (CGA) Specification G - 7.1 according to 29 CFR 1910.134, which has specific requirements for contaminant level and moisture content.
