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.

Programmable logic
airTempC > 37: ceiling exceeded; the employer is in breach of Art. 611 unless the rescue/hazard-prevention proviso applies with health measures. Exactly 37 °C complies. Screening limit only: no work/rest schedule or stop-work trigger. Applies to underground workplaces (industry mining). The Mine Safety Act Enforcement Regulations Art. 16 counterpart was not read and is not modelled.
Required inputs: airTempC
