What are the two colors of high forest fire warning signal?

Red and orange are warning signs of high forest fire risk.

Forest fire risk refers to the possibility of forest fire, which is one of the important indicators to measure the health of forest ecosystem. High forest fire risk means that there is a high possibility of fire, which needs to be paid enough attention to. In order to release forest fire warning information to the public in time, countries usually adopt color coding. In China, the colors of high forest fire warning signals are orange and red.

Orange is an eye-catching color that can attract people's attention. In the forest fire warning signal, orange indicates that there is a greater possibility of fire, and corresponding preventive measures need to be taken. For example, reduce the use of fire in the wild and strengthen the inspection of forest areas. By issuing forest fire warning signals with different colors, the public can know the situation of forest fires in time and take corresponding measures to protect their lives and property. At the same time, it can also remind relevant departments to strengthen forest fire prevention and reduce the occurrence of fires.

Harm of forest fire

1. Destroy the ecological environment: Forest is one of the most important ecosystems on the earth. They can absorb carbon dioxide, release oxygen and adjust the climate. However, forest fires will burn a large area of forests, destroy vegetation and animal habitats, and lead to soil erosion and water pollution. These problems will not only affect the local ecological environment, but also affect global climate change.

2. Huge losses: Forest fires will not only burn a lot of trees and vegetation, but also destroy infrastructure such as houses and roads, causing huge economic losses. In addition, fires may also cause secondary disasters such as explosions and landslides, further aggravating losses.

3. Threatening human life safety: Forest fires will lead to extreme environmental conditions such as smog, high temperature and lack of oxygen, posing a threat to human life safety. Smoke and poisonous gas in the fire will cause harm to people's respiratory system and nervous system, and may even lead to death.
