Description
HALF FACE MASK
-face Respirator Instruction Sheet
Half-face respirators are air-purifying respirators that have the potential to provide protection
from many types of dusts, fogs, fumes, mists, gases, smokes, sprays, or vapors. In order to
gain this protection, it is important that you have the proper setup. A half-face respirator
includes a facepiece or mask, and a filter/cartridge. Cartridges are selected to filter out
specific particulate or chemical substances.
Half-face Respirator Basic Information
Respiratory Protection Program Requirements
The Ohio State University’s Respiratory Protection Program requires that employees must
complete the following steps prior to wearing a respirator:
1. Medical clearance: to determine if employee is physically able to wear a respirator,
conducted by University Health Services
2. Annual fit test: to determine if the respirator fits properly on the user’s face, conducted by
EHS.
3. Annual training: on the selection, use, storage, and limitations of the respirator used
Selecting a Respirator
Employees will only wear the same make, size, and model of respirator that they have been
successfully fitted with during the annual fit test. This model will be chosen during the fit
test, depending on comfort, facial structure, and size. Returning employees will continue
wearing the same respirator as previous years and will be fit tested using this equipment,
unless the respirator has been compromised or will not fit properly any longer.
Cartridge selection will also be determined based on the employee’s specific protection
needs. Typically, cartridges should be changed out when you feel a higher resistance in
breathing or after approximately 8 hours of use.
Capabilities and Limitations
• Cannot be used for all types of air contaminants
• Limited by the type and capacity of the filters or cartridges used
• Does not provide any eye protection
• Cannot be used in oxygen-deficient atmospheres
• Proper fit is essential and many factors may effect the seal to a user’s face
