Public Guidelines for Meteorological Disaster Prevention and Mitigation (Lightning)

1 Scope

GB/T 47319-2026 is the Chinese national standard covering what a person should actually do in a thunderstorm - indoors, outdoors, in the open, in a vehicle, on water - written as public guidance rather than as engineering. First edition, in force since 1 July 2026, under the China Meteorological Administration. It was issued on 31 March 2026 and has been in force since 1 July 2026, as a first edition. The document is under the responsibility of the China Meteorological Administration. This page is published from the official record of the 2026 edition; the clause text of a standard this recent is not yet in circulation, and the figures, limits and tables it contains are those of the document itself, delivered in full with the English translation.

This document establishes general principles for public response to lightning disasters and provides recommendations for pre-disaster prevention, disaster mitigation, and post-disaster relief. This document applies to the prevention, defense, and relief efforts for lightning disasters to the general public.

3 Terms and Definitions

The following terms and definitions apply to this document.

3.1 Lightning lightning Strong electrical discharge phenomena in the atmosphere. [Source: GB/T 19663-2022, 3.2.1, with modifications]

3.2 Lightning Strike A discharge during a ground-to-ground flash. [Source: GB 50057-2010, 2.0.2]

3.3 Contact voltage The potential difference between accessible points that can be simultaneously touched by an organism. [Source: GB/T 19663-2022, 4.16]

3.4 step voltage The potential difference between two points on the ground, a distance of one step.

Note. This distance is taken as 1m in the direction of the maximum potential gradient. [Source: GB/T 19663-2022, 4.17]

3.5 Side Flashover When lightning strikes an object (or forms a lightning current path), the potential difference between adjacent objects and the struck object (or the lightning current path) exceeds the threshold. This is a phenomenon where a breakdown discharge occurs due to the high breakdown field strength of the air, causing damage to nearby objects.

3.6 Lightning protection device A facility or system for protecting against lightning strikes, consisting of a lightning rod, down conductor, grounding device, surge protector, and its connecting conductors.
