This article describes unintentional electricity and air pressure injuries resulting in hospitalisation or death. Intentional injuries are included under Self-harm injuries and suicide or Assault and homicide.
Deaths due to this cause are relatively rare so are described in limited detail in this article.
Injuries by type of exposure
The main categories of electricity and air pressure exposures leading to injury hospitalisation include:
- exposure to electric current: this includes incidents such as burns and other injuries resulting from contact with live wiring, sockets, or unidentified sources.
- exposure to high and low air pressure and changes in air pressure: injuries in this category may arise from situations like the rapid reduction in atmospheric pressure encountered when surfacing from deep-water diving or underground environments, or from extended periods spent at high altitudes.
- other exposures: examples include exposure to ionising radiation (such as X-rays), artificial visible and ultraviolet light (such as that produced during welding), or extreme temperatures involving excessive heat or cold (Table 1).
Table 1: Causes of hospitalisations due to electricity and air pressure, 2024–25| Cause | Hospitalisations | Crude rate (per 100,000) |
|---|
| Exposure to electric current (W85–W87) | 407 | 1.5 |
|---|
| Exposure to high and low air pressure and changes in air pressure (W94) | 211 | 0.8 |
|---|
| Other (W88–W93, W99) | 34 | 0.1 |
|---|
| Total | 652 | 2.4 |

Trends over time
There is a break in the time series for hospitalisations between 2016–17 and 2017–18 due to a change in data collection methods (see the technical notes for details).
The number of injury hospitalisations caused by electricity and air pressure-related injuries has generally decreased over the past decade (Figure 1). Between 2015–16 and 2024–25, the rate decreased from 3.1 to 2.4 per 100,000. The hospitalisation rate in 2024–25 was 9.8% lower than the previous 5-year average of 2.7 per 100,000 population.

Seasonality
Injury hospitalisations related to electricity and air pressure exposures rose during spring and peaked in the early summer (Figure 3). In 2024–25, the peak for injury hospitalisations was observed in December, with 71 hospitalisations.
