Outdoor activities became popular in China in the 1990s. This type of activity, which allows you to exercise while getting close to nature, has gained favor with more and more people. However, some people disregard safety factors, causing outdoor activities to lose their original meaning. In this safety alert column, the Provincial Work Safety Supervision Bureau (Sichuan Coal Mine Safety Supervision Bureau) reminds you: be well-prepared before engaging in outdoor activities.

Purchase accident and casualty insurance before your trip

Any outdoor activity carries risks. Before setting out, please purchase special insurance such as accident and casualty coverage; it is recommended to use appropriate gear. Commonly used equipment includes: ankle supports and hiking shoes with textured soles for better grip, trekking poles, clothing and footwear suitable for hiking, and avoid wearing shorts or short-sleeved shirts. Wear a hat and bring communication tools such as a mobile phone.

Properly manage open flames during outdoor activities to prevent wildfires. In the event of a wildfire, stay calm, evacuate the area quickly, and call the authorities. During summer trips, the likelihood of encountering heavy rain is higher. When heavy rain occurs, immediately leave riverbanks. If you notice fast-flowing, murky water mixed with sand and mud, it may be a sign of an impending flash flood—move away from the river quickly. If bitten by snakes or insects, administer self-rescue treatment immediately, and seek medical attention promptly if the situation is severe.

Bright clothing can send a distress signal

In critical moments, a whistle, mirror, piece of metal, flashlight, bright clothing, as well as stones or branches can all serve as effective tools for sending out distress signals.

The Provincial Work Safety Supervision Bureau (Sichuan Coal Mine Safety Supervision Bureau) teaches you some methods for sending out distress signals: within one minute, blow the whistle to emit six long signals in succession, then pause for one minute and repeat the same signals without interruption until rescue personnel arrive. Even if you have been spotted from a distance, continue sending signals to help rescuers locate your exact position. Use reflective light by employing a mirror or piece of metal to send signals. At night, use a flashlight to emit flashes. Wave bright and vivid clothing. On flat, open ground, stack stones or branches to form the letters “SOS”.
