Protocol
Create a low-interruption zone for fragile work
Sometimes safety is partly an environmental setting.
When it fits
- A high-consequence routine requires sustained concentration and slips cluster around interruptions.
When to avoid it
- Do not use focus protection to block needed peer review or make a single person the uninterruptible bottleneck.
Why it matters
Identify the task phases where distraction is unusually costly and make a temporary interruption rule: physical sign, status mode, closed chat, role coverage or separate workspace. Keep emergency communication available. End the protected state when the fragile phase is complete so the exception does not become permanent isolation.
Steps
- The fragile task receives measurably fewer avoidable interruptions without losing emergency reachability.
An example
During a production data upload and validation window, one operator works without routine chat while a second person handles inbound questions.
Check your result
The fragile task receives measurably fewer avoidable interruptions without losing emergency reachability.
Keep this limit in mind
- Do not use focus protection to block needed peer review or make a single person the uninterruptible bottleneck.

Evidence and sources
AHRQ recommends removing distractions from areas where work requires intense concentration as one slip-reduction strategy.
Collaboration and emergency communication still need controlled access.

Aviation certification practices are highly domain-specific; only general human-system design principles transfer.
