The National Highways Authority of India (NHAI) has directed contractors and concessionaires to provide staggered working hours for workers involved in national highway construction to avoid peak heat between 12 pm and four pm in a bid to mitigate the heatwave effect. It has issued guidelines outlining mandatory safety protocols for construction sites, maintenance work and toll plazas under its jurisdiction. The safety measures will be implemented immediately by contractors, concessionaires and toll collection agencies to protect staff and workers.

Special emphasis has been placed on acclimatisation of workers, ensuring that new or returning personnel are gradually exposed to strenuous tasks over a period of three to five days and trained to identify and respond to heat related illnesses including heatstroke. Emergency preparedness has been strengthened and patrol ambulances will be equipped with ice packs, cold water and IV fluids to support rapid medical response. Route Patrolling Units (RPUs) have been instructed to increase monitoring frequency to assist highway users facing heat related issues and vehicular breakdowns due to overheating.

For toll operations, the authority has advised minimising outdoor exposure of personnel during peak heat hours from eleven am to three pm through optimised shift management and rotational rosters. Night hours will be utilised for administrative and maintenance activities that do not require presence in lane operations. The measures aim to balance the need for continued highway services with protection of worker health.

The directive builds on established best practices and seeks to institutionalise a consistent approach across the national highway network, with accountability placed on contractors and concessionaires for compliance. The NHAI will monitor implementation through routine reviews and coordination with RPUs to ensure timely assistance and effective response during extreme heat episodes.
