South Korea Heatwave Inspections Target 1,000 Workplaces

South Korea's Ministry of Employment and Labour will inspect 1,000 workplaces vulnerable to heat illness and confined-space asphyxiation between 3 and 14 August 2026. Announced on 28 July, the South Korea heatwave inspections cover manufacturing, construction, shipbuilding, logistics and high-risk enclosed work, linking apparent-temperature controls with gas, ventilation and respiratory-protection checks.

South Korea's Ministry of Employment and Labour will inspect 1,000 workplaces vulnerable to heat illness and confined-space asphyxiation between 3 and 14 August 2026. Announced on 28 July, the South Korea heatwave inspections cover manufacturing, construction, shipbuilding, logistics and high-risk enclosed work, linking apparent-temperature controls with gas, ventilation and respiratory-protection checks.

Heat Thresholds Inspectors Will Examine

The ministry says August is expected to bring the most intense heat after the rainy season. Inspectors will assess implementation of the five basic heat-safety rules and staged work-stoppage measures at sites where workers face elevated exposure.

Controls step up from an apparent temperature of 33°C, before the higher stop-work points. At an apparent temperature of 35°C or above, the ministry expects outdoor work to stop or be actively rescheduled. At 38°C or above, all outdoor work should stop except tasks requiring emergency action. These thresholds are operational inspection points within an active enforcement campaign, not a newly enacted standalone statute.

The targeted inspection period ends on 14 August, but the ministry's special heatwave task force will continue site inspections and supervision in alert areas and higher-risk workplaces until 30 September 2026.

Confined-Space And Toxic-Gas Controls

The South Korea heatwave inspections also address enclosed spaces because heat can reduce oxygen levels and increase the release of toxic gases such as hydrogen sulphide. Manholes, wastewater-treatment facilities and storage tanks are highlighted. The ministry says work should not proceed without hazardous-gas measurement, sufficient pre-entry ventilation and supplied-air respiratory protection.

Manufacturers and contractors should verify that entry permits, atmospheric testing, ventilation, rescue arrangements, communications and equipment checks work in practice. Site owners should confirm how contractor controls are supervised and how changing weather affects simultaneous operations, maintenance and emergency response.

Immediate Action For Employers And Suppliers

Employers should connect forecast and apparent-temperature data to documented stop-work decisions, shift changes, hydration, rest and worker communication. Supervisors need authority to halt work without delay. Equipment suppliers and service providers should confirm that gas monitors, ventilation systems and respirators are suitable, maintained and available at the point of use before inspectors arrive. The South Korea heatwave inspections make documented readiness an immediate operational priority.

Questions about this change

What Temperature Controls Will South Korean Inspectors Check?

At an apparent temperature of 35°C or above, outdoor work should stop or be rescheduled. At 38°C or above, all outdoor work should stop except emergency tasks. Employers should connect forecasts and site measurements to documented decisions, ensure supervisors can halt work and communicate changes promptly to workers and contractors.

What Confined-Space Controls Are Highlighted?

The ministry highlights hazardous-gas measurement, sufficient ventilation before entry and supplied-air respiratory protection. Employers should also verify permits, communications, rescue plans, equipment maintenance and contractor supervision for manholes, wastewater facilities, tanks and similar spaces. Heat can reduce oxygen and increase toxic gases such as hydrogen sulphide, raising asphyxiation risk significantly.
