This rule has no numeric trigger the calculator evaluates — it states duties and control measures rather than a threshold a reading can be checked against. Its measures are listed below.
No standalone formula is published for this standard; see programmable logic and parameters below.
| Parameter | Value |
|---|---|
maxAirTempC | 26 |
Programmable logic
airTempC > 26: ceiling exceeded; air cooling must be provided. Screening limit only: no work/rest schedule or stop-work trigger. Applies to mining (industry mining). The paragraph number was not captured. Coal mines have their own FNP; not modelled here.
Required inputs: airTempC
Optional inputs: none
This standard was added to the calculator.
This standard’s output changed in the reference scenarios, in a form that does not reduce to permitted work minutes (for example a screening limit, risk level, or respirator tier).
Get notified when Russia Rostekhnadzor Order No. 505 (2020) Mining Safety Rules — air temperature at faces and permanent workplaces changes — threshold changes, scope and legal-status changes, additions and removals. Changes that permit more heat exposure than before are labelled as such.

If a threshold, trigger, exemption, date or duty here disagrees with the governing text, tell us and point at the section. The form arrives with this standard already named, and a correction is checked against the same primary document it was encoded from.
