Pay attention to safety tips in windy days.

Lead: Wind power can be divided into 18, with the minimum being 0 and the maximum being 17. Some friends want to know something about windy weather. Let's have a look. Pay attention to safety in windy weather. What are the sentences that pay attention to safety tips in windy days? If you have friends who don't know, please learn from me. I hope everyone likes reading.

Pay attention to safety sentences in windy weather

Avoid the "narrow tube effect". Pay attention to the long and narrow passages between tall buildings when walking or cycling. Because the narrow passage will form a "narrow tube effect", the wind in the passage will increase, which will bring certain danger to pedestrians.

Be careful of falling objects. Stay away from tree signs, street signs and fences, and don't stay around for a long time.

Drive carefully. When driving in strong wind, you should reduce the speed appropriately, correctly identify the wind direction, and hold the steering wheel tightly to prevent the driving route from deviating due to the wind. Pay attention to the lateral stability of vehicles and reduce overtaking.

Light vehicles are heavier. Because of its light weight, light vehicles may be lifted by strong winds when driving at high speed. You should put some heavy things on the light car or drive slowly.

Ride less bicycles. In windy weather, once you ride in the crosswind, you may be blown down by the gale and cause physical injury.

Wear a mask when going out. Protect the respiratory tract and avoid diseases such as colds, tracheitis and pneumonia. It is recommended to wear a mask and change it every day.

Don't rub foreign objects into your eyes. It is easy to cause foreign bodies to enter the eyes in windy days, and rubbing the eyes is easy to scratch the cornea.

Safe production and operation in windy weather

Enterprises producing dangerous chemicals. Strengthen the windproof measures for open-air and semi-open-air warehouses, and strengthen the windproof and dustproof inspection of detection and alarm instruments.

Gas station, oil depot. Timely check the weak parts such as awnings, billboards and sign posts in the reinforcement station, and stop aerial work.

Fireworks and firecrackers management (wholesale) enterprises. Strengthen the inspection of the warehouse roof, doors and windows to prevent them from being overturned.

Mining enterprises. Suspend the hoisting of open-pit mining system, coal mine and non-explosive mine enterprise dump and ground bunker, as well as high-altitude production operations as appropriate, and evacuate relevant personnel when necessary.

Fire safety in windy weather

Don't throw cigarette butts about. In windy weather, we must always pay attention to the use and storage of cigarette butts, ash, matches, lighters and other dangerous goods.

Do not burn paper or incense in the open air. In the process of burning paper, many unburned paper ashes or burning incense sticks are easily blown to haystacks and other places by the wind, which can easily lead to fires. Therefore, we must take a civilized memorial service and don't burn paper and incense in the open air in windy weather.

It is forbidden to ignite and burn crops. If hot work is needed in spring ploughing production, it should be supervised by special personnel, pay attention to the nearby environment, stay away from flammable and combustible substances such as mountains, forest areas and haystacks, and take fire prevention measures in advance.

Illegal operation is prohibited. It is forbidden to carry out inflammable and explosive dangerous labor operations such as open flame and electric welding outdoors in windy weather. If it is necessary to use open flame, welding and other operations should be carried out in strict accordance with the operating procedures.

Note that catkins are flammable. It's almost the peak of catkin flying. Catkin meets an open flame, which will immediately cause baking and burning, and spread very fast, and it is easy to be ignited and become a fuse.

Measurement method of wind power grade

In order to measure the wind more accurately, people often use portable anemometers to measure the wind in the field. This kind of portable anemometer generally consists of an induction part and a counter (see the left picture). The induction part consists of three air cups (there are also four air cups) installed on the cross. The air cups can rotate freely on bearings and are protected by a small frame. The lower part of the central shaft is connected with the counter, and when the air cup rotates, the counter also rotates. So the counter records the number of revolutions of the air cup. A counter usually has two or three counters, with the large pointer indicating single digits and ten digits, and the pointers on the two small counters indicating hundred digits and single digits respectively. There is a switch (starting lever) at the lower part of the instrument. Pushing up can make the counter engage with the sensing part, and the counter starts to work. When the starting lever is pulled down, the counter is separated from the sensing part and stops working.

When the instrument is placed in a high place and it is not convenient to start it directly by hand, you can connect the switch with a small rope. When observing, you can pull the rope to open and close. Portable anemometers are generally placed in open areas around without tall obstacles, and their bodies are vertical. Turn off the switch before observation and write down the instructions of the pointer. After a minute or two, turn on the switch and start the stopwatch to record the time. At this point, the observer quickly left the anemometer and stood downwind of the instrument. After starting the instrument for nearly 100 seconds, the observer quickly approaches the instrument, turns off the switch at 100 seconds, and records the indication of the second hand. According to the two readings before and after, calculate the difference value, indicating the scale number of anemometer pointer during the observation time, and record it in the record table. Divide this difference by the observation time, and you can get the scale number of anemometer per second, and take one decimal place. Then, according to the number of scales per second, the average wind speed (unit: m/s) is found from the anemometer verification certificate, and one decimal place is taken.

It is best to observe it twice in a row and take its average value to reduce the instrument itself and human error.

Some portable anemometers have not only the structural performance of the anemometer mentioned above, but also a wind vane on the shaft to indicate the wind direction. This kind of anemometer is called anemometer.
