Regulation 180(1): the mine manager must ensure the wet bulb temperature at any working place or travelling way does not exceed 32.5 °C, except in the course of attempting to lower the temperature, emergency response training, or an emergency. Regulation 180(2): the manager must provide longer breaks and a reduced working time for workmen if the wet bulb temperature in the mine exceeds 27 °C.

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 |

Programmable logic
wetBulbC > 32.5: exceeds the reg 180(1) ceiling. wetBulbC > 27: longer breaks and reduced working time (reg 180(2)). Exactly 27 or 32.5 does not trigger. No break length or hours specified. Applies to mines (industry mining); exceptions for lowering temperature, emergency training and emergencies are not modelled.
Required inputs: wetBulbC

Get notified when Ghana Minerals and Mining (Health, Safety and Technical) Regulations 2012 (L.I. 2182) reg 180 — mine wet-bulb 32.5 °C ceiling; 27 °C longer breaks changes — threshold changes, scope and legal-status changes, additions and removals. Changes that permit more heat exposure than before are labelled as such.
