From traffic signals shutdown to SOPs for workers: How states are tackling heatwave

The summer heat has tightened its grip across the country, with the India Meteorological Department (IMD) issuing heatwave alerts as temperatures have already climbed to 40-45 degree Celsius in several regions.

According to the IMD, the heatwave is expected to persist at least until April 22, with severe conditions prevailing in parts of east Rajasthan, Odisha, and Jharkhand. Isolated pockets of extreme heat have also been reported in eastern Uttar Pradesh, eastern Madhya Pradesh, Chhattisgarh, and Vidarbha.

As the heat intensifies, several cities and states have begun implementing measures to provide relief to residents, commuters, and outdoor workers. Many states are activating Heat Action Plans (HAPs), which include initiatives such as cool roofs and the establishment of cooling centres. These efforts are being carried out in coordination with the National Disaster Management Authority (NDMA).

Innovative measures

In an innovative step, civic authorities in Surat, Ahmedabad, and Nagpur have modified traffic signal operations during peak afternoon hours to reduce exposure to the sun. In Surat, traffic signals are switched off between 1 pm and 4 pm, while in Ahmedabad, around 70 signals remain inactive from 12 pm to 4 pm. In Nagpur, 31 key junctions operate in blinker mode between 2 pm and 4 pm, requiring motorists to follow a “Stop, Look, and Go” approach.

The aim is to minimise the time commuters spend idling under direct sunlight and to reduce the risk of electrical failures. Traffic management during these hours depends on driver awareness and strategic deployment of police personnel. Commuters are expected to slow down, check for other vehicles and pedestrians, and proceed cautiously. Traffic police remain stationed at major junctions to prevent congestion and ensure smooth flow of traffic.

At intersections where signals cannot be turned off, authorities have installed green shade nets to provide overhead protection. Water and oral rehydration solution (ORS) stations have also been set up for pedestrians and drivers. In some areas, traffic personnel are using manual control and walkie-talkies to manage congestion and prioritise movement of vehicles.

UP prepared for electricity demand

In Uttar Pradesh, Chief Minister Yogi Adityanath said the government has made comprehensive arrangements to tackle the heat and urged citizens to take precautions. He said the state is preparing to meet a peak electricity demand of around 34,500 MW, with all thermal power plants operating at full capacity.

Measures in the state include water sprinkling on roads, setting up shaded areas, organising health camps at industrial and construction sites, and ensuring treatment facilities for heatstroke patients. Free drinking water is being provided at tehsils, farms, hospitals, and anganwadi centres. Steps are also being taken to protect livestock and wildlife, including implementing heat action plans in zoos and sanctuaries.

In Maharashtra, the government has issued Standard Operating Procedures (SOPs) in 15 high-risk districts, focusing on vulnerable groups such as informal workers, miners, and outdoor labourers. The SOPs mandate adjusted working hours for outdoor labourers, including sanitation workers, delivery personnel, and construction workers, along with provisions for regular water breaks, temporary shelters, and strengthened emergency healthcare services.

IMD advisory

The IMD has advised people to stay hydrated, avoid direct exposure to the sun between 12 pm and 4 pm, and follow health precautions to reduce the risk of heat-related illnesses.
