Description
Qualitative Fit Test (QLFT)
QLFT is pass/fail and relies on the user’s senses using one of four OSHA-accepted test agents, of which Vida First Aid uses two of the four:
- Saccharin (sweet taste); can test respirators with a particulate filter of any class.
- Bitrex® (bitter taste); can also test respirators with particulate filters of any class.
Each QLFT method uses seven exercises performed for 1 minute each:
- Normal breathing.
- Deep breathing.
- Moving head side to side.
- Moving head up and down.
- Bending over (or jogging in place if fit test unit doesn’t permit bending at the waist).
- Talking.
- Normal breathing again.
