Skip "iron out" for emergencies, confirmed legal or compliance breaches, severe safety or security incidents, major outages, or fundamental strategic or people conflicts -- and skip it in formal legal, compliance, board, or incident-report writing even when the underlying matter is comparatively minor. Use a fact-specific verb instead, such as investigate, contain, remediate, report, resolve, or renegotiate.
Two separate reasons, either one enough on its own
Severity. "Iron out" frames a matter as manageable. Using it for a genuine emergency or a confirmed breach under-signals how serious the situation actually is -- it tells a reader "this is routine" when it isn't.
Register. Even a comparatively contained matter should avoid the idiom in a formal legal, board, or compliance document, purely because the document type calls for precise, factual language -- independent of how serious the underlying event turns out to be. A confirmed security or safety incident written up as a formal record fails on both counts at once: it's severe, and it's the wrong register.
"We're just ironing out a minor security issue" understates a confirmed security incident that's disrupting customer access; "We are investigating a security incident affecting customer access, and containment measures are in place" states the facts without minimizing them.
For a confirmed safety incident with an unknown cause, "we are ironing out the safety issue with the site team" is too casual for the initial formal record -- "we are investigating the safety incident and will document the findings and required corrective actions" is fact-appropriate instead.

Adding "just" or "minor" to "iron out" doesn't make a genuine incident sound more reassuring -- it reads as minimizing once the facts turn out to be more serious, which damages trust in every update that follows. If you're not sure whether a situation is serious enough to avoid the idiom, err toward the fact-specific verb; nobody has ever been criticized for describing an incident too precisely.
Practice scenarios
Practice using "iron out" in situations like:

Useful practice phrases:
- "We are investigating the incident and will document the findings."
- "This isn't something to iron out -- it needs to be formally resolved and reported."

"Iron out" is a manageable-sounding word for a manageable-sized problem.
Once the facts are serious or the document is formal, reach for a verb that carries the actual weight of what happened.
