45.5°C in Jhansi: A School Heat Action Plan in 48 Hours
Jhansi, Bundelkhand, last week of May. The IMD forecast is 45.5°C for the next four days; the normal for this period is 41°C. Your government higher secondary school has 720 students, a tin-roofed assembly hall, three hand pumps in the open, no water cooler, ceiling fans in the classrooms but none in the hall, and Classes 9 and 10 pre-board examinations scheduled every morning from 7 a.m. Last May, 12 students fainted during a function in the hall at 11 a.m. and two were taken to the district hospital. Most students walk 2-5 km to school, and about 90 come from homes with no electricity. The district has issued a heat alert, and the block education officer has asked every school for a heat action plan within 48 hours. Some teachers want a holiday; others say the pre-boards cannot be postponed.
1. Is 45.5°C a heatwave by IMD criteria? Use the answer to decide the school's timings and whether to close.
Read the worked answer
Applying IMD criteria: in the plains, a heatwave is declared when the maximum is at least 40°C and the departure from normal is 4.5-6.4°C; it becomes a severe heatwave when the departure exceeds 6.4°C or the actual maximum reaches 45°C. Here the maximum is 45.5°C against a normal of 41°C - a departure of 4.5°C and an absolute value above 45°C. This is a heatwave, and severe conditions apply. The district alert is consistent with the data.
School timings: move to a single morning session, roughly 6:30-10:30 a.m. No assembly, no outdoor games, and no function in the tin-roofed hall after 10 a.m. - a tin roof with no fans is the hottest place on campus and is where the 12 students collapsed last year. Hold the pre-boards in the first two periods in the coolest rooms.
Close or not? Not automatically. A blanket holiday pushes 90 students into homes with no electricity, and some into outdoor work, while the examination still has to happen. But if the forecast crosses about 47°C, or the district declares a red alert, close the school and notify parents the previous evening.
2. Who in this school is most at risk, and what targeted measures would you build into the plan rather than general advice to drink water?
Read the worked answer
Risk is not uniform. The general advice reaches the students who need it least. Rank the groups:
- The 90 students from homes without electricity: no fan at night means poor sleep and a heat load carried into the school day.
- Students walking 2-5 km over tarred, unshaded roads, especially if they arrive after 10 a.m.
- Children with chronic conditions - check the school health record for sickle cell disease, asthma or heart conditions - and children with disabilities.
- Students who arrive without a water bottle, often the poorest.
Targeted measures:
- Stagger departure so no group walks home in the afternoon peak, and organise a buddy system on the walk.
- A shaded water point and ORS at the gate, with teachers checking bottles at roll call for the no-electricity group.
- A cool rest room with fans for anyone with headache, cramps or dizziness; a fainting student is cooled, laid flat with legs raised, and referred, not sent home alone.
- A phone call to the families of the most at-risk children, and a written register of who they are. General advice does not reach these groups; a named list does.
3. Link this event to climate change and to the district heat action plan. What would you ask the district for, and why is this not just bad weather?
Read the worked answer
Weather versus climate. A single hot day is weather. What the record shows is a trend: heatwaves in India have become more frequent, longer and more intense, with hotter nights, and attribution studies indicate that climate change has made events of this kind more likely and more severe. That is why the school's plan should not be written for one week; it becomes an annual standing item reviewed every March, before the season.
What to ask the district for:
- The heat action plan's threshold levels and a warning channel that reaches the head teacher directly, by SMS or WhatsApp, not through the newspaper.
- Drinking water and shade at school gates and along the main walking routes, and tree planting on those routes.
- A ventilated or reflective roof for the hall, or insulation and fans, since that is where students collapsed.
- A rest room, ORS stock, and a clear written rule on when the district will declare a holiday.
Why it matters: the tin roof, the unshaded walk and the missing fans are vulnerabilities, not acts of nature. They can be fixed, and fixing them is disaster risk reduction, not charity.
