Several levels of typhoon response need to be stopped.

Stop work when the typhoon reaches level 6.

When the outdoor typhoon reaches level 6 or above, the relevant outdoor staff should stop working. For example, when there is strong wind of magnitude 6 or above in the open air or bad weather such as heavy rain, heavy snow and fog, the lifting operation should be stopped. After the rain and snow, before the operation, try hoisting first, and then make sure that the brakes are sensitive and reliable before the operation. Typhoon of magnitude 8 or above may or has been affected by tropical cyclones within 24 hours, and the average wind force is above magnitude 8, so classes will be suspended.

The suspension of classes is not clearly defined, depending on the impact of the disaster. Some typhoons are of great magnitude, but they are far away from the mainland and attend classes as usual. Some classes are very small, but if the normal life is affected by heavy rain, classes will be suspended.

How to avoid danger when the typhoon comes?

1, try not to go out. If you are outdoors, don't shelter from the wind and rain near temporary buildings, billboards, iron towers and trees. If you are driving, you should immediately drive to the underground parking lot or shelter.

If you live in a tent, you should immediately put away the tent and take shelter from the wind in a solid house. If you are on water (such as swimming), you should immediately go ashore to avoid the wind and rain.

3. If you are already in a solid house, close the window carefully and stick a "meter" pattern on the window glass with tape to prevent the window glass from breaking. If there is typhoon and thunder, lightning protection measures should be taken. After the typhoon, we should pay attention to environmental hygiene and the safety of food and water.

4. Open-air collective activities or indoor large-scale gatherings should be cancelled in time, and personnel should be evacuated. Don't travel to the area where the typhoon passes or swim on the beach, let alone go out to sea by boat.
