Do not use the mouth to open the chemical container/vessel.
Do not use bare hands to mix pesticides, but the stick.
Mix pesticides outside the house or in the open air with good ventilation.
While mixing pesticides, do not smoke, have food, or drink some water until the hands are completely cleansed.
Do not breathe the pesticide dust in while mixing them, and use proper devices to protect eyes and face
2)During the use of pesticide
During every spraying of any pesticide, the user must wear protection tools such as hat, glove, mask, and clothes covering all body parts.
The pesticide spraying should be windward, and stop spraying in case of strong wind.
Do not let children or pets get into the spraying area.
In case that the nozzle becomes clogged, do not use the mouth to blow or suck, but use a small wire to move the clog out.
Do not drink water or have food or smoke while spraying pesticides.
Be careful not to let pesticides splash the body. Any splashed part must be immediately cleansed by soap and fresh water.
If feeling sick while spraying, stop the spraying immediately, and go to see the doctor and show the doctor the vessel containing that pesticide used in that spraying.
3) After the spraying of pesticides
Do not wash all vessels/containers or spraying devices in any river or canal.
Do not use all vessels or containers previously containing the pesticides for other purposes, but destroy them by burning or burying them deeply in ground. Both burning and burying should be far away from water sources.
After each spraying, the user must clean up the body and clothes.
Keep pesticides from food storages of men and animals, and out of children’s reach.
Pesticide vessels or containers must be remarked clearly.
Label or set the warning sign for the sprayed areas.
Should not harvest any plants or vegetables sprayed by pesticides untimely.
4) Keeping the pesticides
Separate the pesticide store from other locations. The specific chemical store may be built if possible.
Pesticides should be kept in a store or room that can be locked with a warning sign.
Pesticide storing location should be ventilative because if pesticides are kept in high temperature, their efficiency will be less, and the hot condition will make some poisonous chemicals expand, which cause high pressure inside the splash the farmer. Moreover, some chemicals may burn by themselves in case of too vessel/container. Then, when opening that vessel/container, pesticides will spurt and high temperature.
Chemicals should be kept in their original vessels/containers and their labels are stuck and seen clearly.
Chemicals should not be kept in other vessels/containers usually used for food or beverage.
Avoid keeping large amount of chemical.
5) Destruction of poisonous substances and containers
When pesticide spill on the floor, use the sawdust or lime to absorb.
Break all pesticide vessels/containers into pieces when the pesticide is out, and bury them carefully. Do not wash such vessels/containers and further use them to fill others objects.
Do not burn the plastic containers or vessels containing chemicals that have pressure inside them because it may cause the explosion.
The remaining and unwanted chemicals must be buried in a deep hole, which is filled with lime on the bottom of the hole. The hole must be far from water sources. Such chemicals must not be poured into any water sources.
Prevention of Using Pesticides
For the prevention of using pesticides, particularly risky ones such as farmers who regularly use pesticides or others who may touch them should have careful uses, not letting them get into the body. These toxic chemicals can get into our body in 3 ways: skin, lungs, and mouth. The best prevention measures should be:
1) Consideration the Necessity
Paiboon Boonchai (1997: 69) stated that before using pesticides, farmers should consider whether their plants and crops were being damaged by insects or not. If yes, they had to consider further the amount of insects. If there were few insects, it was not necessary to use pesticides because the existence of insects was so common in nature. But, if a great number of insects existed, farmers should survey their types so that uses of toxic chemicals were relevant to those insects.
2) Studying Product Labels
Farmers or users must read product labels carefully before each use. If they do not understand those suggestions, they should consult other knowledgeable persons or experts. Users must remember cautions and warnings of its danger while holding these concentrated products, and spraying these diluted products. Moreover, they should wear proper preventive clothes to avoid any danger as advised on most product labels. Some pesticides must be used more carefully and strictly than others. Users must notice the color bar indicating the level of toxicity, illustration, or other additional advices that must be followed except general suggestions.
3) Prevention of Splashing the Skin
When pouring or mixing concentrated products, one must be careful by not letting them drop on skin or clothes. In case that it splashes on skin or eyes, rinse it out immediately. In the event that its great amount splashes on clothes, use the detergent to wash them immediately. Users must use the appropriate measures to transfer or measure their amount. Do not absolutely take scoop up, or stir them by bare hands. While spraying these mixed chemicals, try to walk windward to avoid the blowing of chemical dust. Tools for these chemicals must be used and maintained by right methods. Do not use leaky tools because some chemicals will untidy hands easily. Do not suck or blow the clogged nuzzle, but wash it in water and insert that nuzzle by small wire or item.
4) Body Hygienic Care
Self-hygienic care while spraying chemicals is strongly important. Do not drinks, eat, or smoke while handling the pesticides. Also, do not touch face or skin by hands dirtied by the pesticide or, even wearing the gloves while injecting, users must wash their hands and face every time they finished each injection before drinking some water, having food, smoking, or going to the toilette. In countries where the weather is hot and humidity is high, there is usually a problem of using preventive tools because they may cause users feel uncomfortable or weak from the hot climate. So, farmers should select low-toxicity pesticides that can be used without special preventive tools. But, if such chemicals cannot be found, users should spray these chemicals at the time it is not so hot so that they will feel more comfortable. But, it is hotter; users must wear all protective tools.
5) Clothes for Working
In using all kinds of pesticides, it is necessary to wear comfortable clothes . for close and safe protection such as long-sleeve shirt for the top half of body, covering for the bottom half of body from waist to shoes Moreover, for hat and other wearing clothes, the more they are thick, the better they are able to prevent the absorption of chemicals. Do not forget that the trouser legs must cover shoes; otherwise the toxin may possibly run into shoes
6) Clothes Caring
Clothes worn in each chemical spray must be kept carefully. In case that they are torn or damaged, they must be repaired so that they are in good conditions because chemicals may absorb into the body through these torn clothes easily. Users must check their shoes all the time that they are suitable and good enough or not. I they are leaky or torn, users must change them immediately. The best way is to have 2 pairs of shoes when one of them may be dirtied by chemicals. Clothes and shoes should be cleansed by the powdered detergent everyday and they should be washed separately and kept from other general clothes.
