STANDARD OPERATING PROCEDURE<br />

COLLEGE STATION FIRE DEPARTMENT<br />

SUBJECT: Quantitative Fit Test (PortaCount Plus) SOP: 300.2.40<br />

CATEGORY: Fire Operations PAGE: 1 of 2<br />

APPROVED BY:<br />

Chief, Fire Department DATE: 11/02<br />

Purpose<br />

1) To conduct SCBA mask fit testing prior to use and conduct annual mask fit testing of all certified<br />

personnel.<br />

2) Develop guidelines for records maintenance of fitting testing. Maintain fit test records to include date,<br />

type of test, employee information and type of facepiece used (Facepiece must be the same type/size as<br />

used by the employee).<br />

Requirements<br />

1) Facial hair may not interfere with the facepiece seal or valve function<br />

(e.g., clean-shaven where the seal surface touches the face) including stubble, sideburns, or<br />

beards.<br />

2) The employee must pass a user facepiece seal test (see <strong>procedure</strong>s section below) before<br />

proceeding to the fit test.<br />

3) The test can not be given to an employee who has smoked in the last 30 minutes.<br />

Note: Requirement #1 Achieving an acceptable seal under “test” conditions (e.g., passing the<br />

quantitative PortaCouunt test with facial hair where the seal surface touches the skin) may be achieved,<br />

however, this does not mean a reliable seal can be consistently achieved under “ real world conditions”.<br />

The following rule will apply. The area where the facepiece seal surface touches the face, WILL BE<br />

CLEAN-SHAVEN.<br />

Quantitative fit test (PortaCount)<br />

Procedures<br />

1) The employee shall be allowed to pick from a number of sizes ( Sm. Med. Or Large) so that the facepiece<br />

is acceptable to, and correctly fits, the employee.<br />

2) The employee shall be shown how to properly don the facepiece, including how it should be<br />

positioned on the face, how to set the strap tension and how to determine an acceptable fit.<br />

3) The following criteria shall be used to help determine the adequacy of the facepiece fit:<br />

a) Chin properly placed<br />

b) Adequate strap tension, not overly tightened<br />

c) Facepiece of proper size to span distance from nose to chin<br />

d) Tendency of facepiece to slip<br />

4) A user seal check will be performed as follows: facepiece to be held inplace by hand, no straps, the<br />

employee shall seat the mask on his/her face by moving the head slowly from side-to-side and<br />

up/down. Close off the inlet opening of the face piece using a rubber plug or <strong>fire</strong>hawk regulator (scba<br />

with the cylinder valve closed) At this time the employee takes in a slow, deep breath, collapsing the<br />

face piece slightly. Remove the hand from the facepiece and hold the breath for ten (10) seconds, if the<br />

facepiece remains slightly collapsed and no leakage of air is detected, the employee has passed the<br />

manufacturers (MSA) user seal check guidelines. Another facepiece shall be selected and retested if<br />

the employee fails the user seal check test.<br />
