Job Safety Analysis (JSA)
Break every task into steps, expose the hazards in each, and lock in controls following the hierarchy — then put the approved JSA in your crew's hands before the job starts.
Built to run job safety analysis (jsa) end to end
Knowella turns the JSA (also called JHA) from a binder no one reads into a living, mobile-first control.
Step-by-step task breakdown
Decompose each job into sequential steps, identify the hazards in every step, and assign controls — building a clear, repeatable analysis that mirrors how the work is actually done.
Hierarchy-of-controls enforcement
For each hazard, controls are selected against the hierarchy of controls, prioritizing elimination and engineering over administrative measures and PPE, with the choice documented.
Reusable JSA library
Build a library of approved JSAs by task and trade that crews clone and adapt for similar jobs, ensuring consistency while still accounting for site-specific conditions.
Pre-job field review & sign-on
Crews review and sign the JSA on mobile at the worksite, noting changed conditions with photos. Updates feed back to improve the master analysis.

Questions, answered
What's the difference between a JSA and a permit to work here?
The JSA analyzes hazards and controls for a task; you can link it to a permit-to-work or pre-task plan so high-risk jobs require a completed, approved JSA before the permit is issued.
How do JSAs stay current as conditions change?
Crews flag changed conditions during the pre-job review, and those notes route back to the JSA owner, so the master document evolves with real field experience rather than going stale.
Can supervisors require a JSA sign-on before work begins?
Yes. You can configure the workflow so each crew member must review and digitally acknowledge the JSA, creating a timestamped record that controls were communicated before the task started.
