Summary
In short
- A hearing protection fit check is an assessment used in KnowHealth that checks that a worker's hearing protection actually fits and gives the attenuation assumed. It is built against NIOSH, CSA Z94.2 and forms part of the Hearing Conservation programme.
- Run at issue and periodically. Carried out by a trained assessor.
- The template holds 35 fields across 4 sections.
- Scoring is personal attenuation rating, where high is good.
- NIOSH is national Institute for Occupational Safety and Health. United States research body. Publishes recommended limits and assessment methods, not law.
- It connects to the rest of the library: links Worker, Asset.
What it is
What it is
What is a hearing protection fit check?
A hearing protection fit check is an assessment used in KnowHealth that checks that a worker's hearing protection actually fits and gives the attenuation assumed. It is built against NIOSH, CSA Z94.2 and forms part of the Hearing Conservation programme.
When is a hearing protection fit check completed?
A hearing protection fit check is completed when the task, area or population being assessed is new or has materially changed. Run at issue and periodically.
When to use it
When to use it, and when not to
This assessment is one step in a larger programme. Using it for work that belongs to a neighbouring template produces records that are hard to report on later.
Use it for
- The event or activity this assessment covers has occurred, or is about to
- A new record is needed; each one gets its own ID in the form HPF-2026-000
- You are running the Hearing Conservation programme and this is one of its steps
- A linked record needs this one to exist: links worker, asset
Not for
- Audiometric Test Record, which records a worker's hearing test results.
- Standard Threshold Shift Review, which reviews a detected hearing shift to decide whether it is work related and what to do.
- Noise Survey, which maps noise levels across an area to identify where protection and controls are needed.
- Anything outside KnowHealth, which belongs in the workspace that owns that process

FAQ
Frequently asked questions
What is the hearing protection fit check template based on?+
It is built against NIOSH, CSA Z94.2. NIOSH is national Institute for Occupational Safety and Health. United States research body. Publishes recommended limits and assessment methods, not law. CSA Z94.2 is hearing protection devices. Selection, care and use of hearing protectors.
What sections does the hearing protection fit check contain?+
There are 4 sections: header, fit check, suitability, outcome. Together they hold 35 fields, 26 of which are required.
How often is a hearing protection fit check raised?+
A new record is raised when the task, area or population being assessed is new or has materially changed. Each one is given an ID in the form HPF-2026-000, so it can be traced and referenced from other records.
Which programme does the hearing protection fit check belong to?+
It is part of Hearing Conservation. Exposure known, controls attempted before protection, and shifts in hearing detected early.
How is a hearing protection fit check scored?+
Scoring is personal attenuation rating. High is good. Scores exist to make the form tell you something, not to produce a percentage for its own sake.
Can the hearing protection fit check template be changed?+
Yes. Every field, option, score and conditional rule is editable, and the links to other templates come with it. Most teams install it as it is, run it for a cycle, then adjust.
The agents
What the agents do with it
The form is the easy part. Keeping it current, routing it to the right owner and holding the evidence together is the work that actually slips.
Holds the hearing protection fit check library against your registers, routes each record to its owner, and keeps the evidence trail together.
Coordinates the crew, rolls completion and exceptions into one view, and holds every write for your approval before it touches a record.
This template lives in KnowHealth — employee wellbeing. Exposure monitoring, health surveillance, case management and return to work.
