30-30 Rule Urged as Lightning Deaths Rise Nationwide

As lightning strikes continue to claim lives across Bangladesh, experts are urging people to follow a simple safety guideline known as the “30–30 rule,” saying it can significantly reduce fatalities.

At least 72 people have died from lightning so far this year, many of them farmers working in open fields. In one recent incident, 14 people were killed in a single day on April 26, according to the Save the Society and Thunderstorm Awareness Forum.

Despite improved forecasting by the Bangladesh Meteorological Department, deaths remain frequent, as warnings are often not followed by immediate action.

“The key is not just hearing the warning, but knowing what to do,” said Dr Muhammad Abul Kalam Mallik, a senior meteorologist. “The 30–30 rule is one of the simplest and most effective ways to stay safe.”

The rule works in two steps. After seeing lightning, a person should start counting. If thunder is heard within 30 seconds, the storm is close enough to pose a serious threat, and immediate shelter should be taken indoors. Once inside, people should wait at least 30 minutes after the last thunder before going বাইরে again.

Experts say many deaths occur because people remain outdoors too long, often continuing farm work, tending livestock, or underestimating the danger.

Rural areas are particularly vulnerable due to wide open fields. In many cases, victims are struck while standing under trees or crossing fields during storms, both of which offer little protection.

Authorities are promoting a simple message: “When thunder roars, go indoors.” Hearing thunder means a person is already within striking distance.

Bangladesh declared lightning a national disaster in 2016 after a sharp rise in deaths. Official data shows hundreds of fatalities each year, including a peak of 427 deaths in 2020.

Experts say increasing awareness of the 30–30 rule, especially in rural communities, could help reduce casualties.

They also stress the need for practical measures such as building lightning-safe shelters in vulnerable areas like haor regions, where reaching safe structures quickly can be difficult.

Public awareness campaigns through radio, television, and community outreach are seen as essential to changing behaviour.

Experts also advise farmers to take basic precautions, including seeking shelter as soon as dark clouds appear, avoiding trees during storms, and wearing footwear while working in the fields.

“Lightning cannot be prevented, but deaths can be avoided,” Mallik said. “Awareness and quick action are critical.”
