Vegetable farmers must see! Winter greenhouse vegetable base, these security risks must pay attention to!

1, the shed body, the shed film is not secure hidden danger

It is necessary to regularly check and repair the structure of the greenhouse, and pay attention to safety protection measures and standardized operations during the construction, maintenance or film replacement of the greenhouse, to prevent the collapse of the shed and the risk of manual maintenance and fall.

To compact the film, check whether the film rope is tight, mainly in winter wind weather, afraid of lifting the film, especially some vegetable bases under the high-voltage line, but also pay attention to safety. If the shed film is rolled with wire, it will cause short circuit and large area power failure.

2, winter warm quilt greenhouse operation hidden dangers

Winter warm greenhouse quilts should pay attention to safety when rolled up, sometimes up and down the curtain overload operation, in case it is not firm, it is easy to roll people into.

3, artificial warming causes security risks

Greenhouse materials are often covered with plastic film, and some are also covered with a layer of cotton or non-woven fabric in the plastic shed to keep warm, but these components are flammable items, and they will burn quickly in the event of fire. When the weather is dry and the wind is strong, it is easier to burn. In the wild, once a greenhouse is on fire, it will spread to neighboring greenhouses, and it will spread faster in high winds and dry weather.

First, artificial warming leads to open fires.

In particular, the wind and the weather need to be heated at night, less than 5 degrees Celsius began to warm, rainy days do not need. The best practical industrial candles, two and a half of that specification, can burn 8-10 hours at a time, placed on the ground, an mu of land can be put 30-40, burning evenly, safe and controllable, 10 o 'clock at night can be placed there to heat.

If it is warming block or firewood, it is either burning for 4 hours, or it is burning unevenly or it is important to squat for a long time, people are more tired.

When the temperature in the shed exceeds 32° during the day, it is necessary to conduct a short windbreak, and the ventilation time does not exceed half an hour.

In particular, it is strictly prohibited to illegally live in the shed, open fire heating, flying line charging, high-power electrical appliances, not to mention cooking in the shed.

The second is the hidden danger of fuel engine temperature increase.

High-power fuel heating machine, easy to leak, or cause open flame. Small diesel greenhouse heaters must use regular clean diesel or kerosene, and replace the corresponding diesel label in time according to weather conditions. To follow the correct on and off process, especially in the shutdown, do not pull the power directly, to wait for the fan to stop rotating before pulling the power.

In construction sites or places where the voltage is unstable, connect the regulated power supply. When using the machine, it is necessary to ensure sufficient air intake, and to keep the radius of the equipment within 2 meters without combustible objects.

In addition, the outlet temperature of the heater is very high, and it is strictly prohibited to blow directly on flammable and explosive items. When the machine is refueling, be sure to stop and power off. In order to prevent oil contamination of electrical equipment such as circuit boards, it is necessary to use a special oiler to refuel. Once the small diesel greenhouse heater does not work normally, please stop using it immediately and contact after-sales maintenance personnel.

Third, prevent carbon monoxide poisoning.

In order to facilitate and strengthen the management of greenhouses, some farmers will move to live in the shed in winter, the night weather is cold, many farmers will make fire heating and cooking in the greenhouse room, coupled with poor ventilation in the shed, it is easy to cause carbon monoxide poisoning, and fire at night is more likely to cause casualties. Because the density of carbon monoxide is slightly lower than that of air, it exists in the upper space, and the second film should be opened when the shed is toured in the morning during the day to release carbon monoxide.

4. Hidden dangers of line aging

There may be security risks in vegetable greenhouse electricity, because of long-term exposure to high temperature, high humidity environment, vegetable greenhouse electrical equipment and wires are easy to age and damage, resulting in leakage caused by the total protection trip. It is necessary to focus on checking whether the operation of electricity facilities is safe, and remind the relevant responsible personnel to replace the aging lines, gate knives, socket switches and leakage protectors in time.

Greenhouse lighting generally use mine lamps or flashlights, try not to use wired electrical lighting, if must be used when the bulb should not be higher than 60W, and the bulb should be left with the roof of the shed no less than 60cm distance.

In addition, do not stack flammable and explosive items in or around the greenhouses (pesticides and fertilizers are opened, afraid of causing chemical reactions), and regularly do a good job of environmental remediation, especially regularly clean up abandoned shed film, weed straw and other flammable waste. In addition, all places should inspect the compost pool and the well of the vegetable base to see if there are warning signs and protective measures.
