SanPiN thresholds start at 28.5°C for light work — try 29°C
Why This Is Legal
2
Labor Code Mandates Reduction
When actual temperature exceeds the threshold, Labor Code Article 221 mandates reduced workday: 1 hour at 28.5°C+, 2 hours at 29°C+, 4 hours at 30.5°C+ (light work, 8-hr shift).

Employer Must Provide Safe Conditions
Article 212 TK RF requires employers to provide safe conditions — heat mitigation or reduced hours.
