Appendix F: Fit Test Adapters
Fit test adapters are
required to create an
interface between the
QuantiFit2 and the
respirator. These adapters
are inserted where the
filters, cartridges, or
regulators mount to the
respirator.
Each respirator manufacturer has its own unique cartridges, filters, or regulators to attach to
their models. OHD matches the connections which will allow an interface.
In the case of an SCBA, the respirator might be required to be converted to an air-purifying
respirator.
OSHA 1910.134(f)(8)(i)
Qualitative fit testing of these respirators shall be accomplished by temporarily converting the
respirator user's actual facepiece into a negative pressure respirator with appropriate filters, or by
using an identical negative pressure air-purifying respirator facepiece with the same sealing
surfaces as a surrogate for the atmosphere-supplying or powered air-purifying respirator facepiece.
OHD testing adapters must be maintained with great care. Any dents or cracks that can occur
will lose the ability to keep an air-tight seal, which would make it inadequate for testing.
Adapters can come in a one-
piece or two-piece arrangement
called "kits." The two-piece kit is
for the bayonet connection, or
connections on either side of the
respirator. These are used mostly
for air purifying respirators. The
one-piece adapters take the place
of a gas filter or SCBA connection
and are typically used on those types of respirators.
When attaching the hose assembly for testing, the blue hose always connects to the single port,
and the gray and transparent hoses connect to the two ports side-by-side. For the gray and
transparent tubes, it does not matter which connector gets which hose as long as the blue
connects to the single port.
Adapters can be cleaned or disinfected in various ways. A disinfectant spray can be used, or the
adapter may be submerged in a disinfectant liquid solution. The adapter should be dried before
the next use.
