1、儲罐清洗前需打開儲罐通風(fēng)。
1. It is necessary to open the storage tank before cleaning.
外加劑一般都要求密閉儲存，存放于陰涼通風(fēng)處，避免雨水污染或陽光暴曬。長期密閉存儲極易導(dǎo)致儲罐內(nèi)氧氣不足。外加劑特別是萘系磺酸鹽系列外加劑產(chǎn)品，由于生產(chǎn)過程中本身要使用甲醛、濃硫酸、工業(yè)萘等有毒化工原料，夏天溫度高時，在儲罐內(nèi)也會釋放大量甲醛等有毒氣體。所以商混站在進行外加劑儲罐之前，需要事先打開儲罐進行必要的通風(fēng)。
Admixtures are generally required to be kept in closed storage and stored in a cool and ventilated place to avoid rainwater pollution or sun exposure. Long term closed storage is very easy to lead to insufficient oxygen in the tank. Admixtures, especially naphthalene sulfonate series admixture products, because the production process itself uses formaldehyde, sulfuric acid, industrial naphthalene and other toxic chemical raw materials, in summer, when the temperature is high, in the storage tank will also release a lot of toxic gases such as formaldehyde. So before the commercial mixing station is carrying on the admixture tank, it is necessary to open the tank in advance for the necessary ventilation.
2、清洗儲罐時需輪流作業(yè)。
2. When cleaning the tank, it is necessary to work in rotation.
外加劑儲罐口徑較小，工人在儲罐內(nèi)清理作業(yè)時，大強度的勞動強度會導(dǎo)致儲罐內(nèi)氧氣不足。在進行儲罐清理時，需要2-3名公司輪流作業(yè)清理，每10-15分鐘輪換，避免單人作業(yè)。若條件允許，在外加劑儲罐入口處放置一臺電風(fēng)扇，一方面可加速儲罐內(nèi)空氣流動，也可以降低儲罐內(nèi)溫度。
As the caliber of the admixture tank is small, the high intensity of labor intensity will lead to the lack of oxygen in the tank when the workers are cleaning the operation in the tank. In the process of tank cleaning, 2-3 companies are required to take turns to clean up and rotate every 10-15 minutes to avoid single work. If the conditions permit, an electric fan is placed at the entrance of the admixture tank. On the one hand, the air flow in the tank can be accelerated and the temperature in the tank can be reduced.
3、儲罐清洗必須配備相應(yīng)的防護措施。
3, it must be equipped with corresponding protective measures.
工人在進入儲罐清理之前，必須配備安全繩、防護罩、雨靴等防護措施。外加劑本身屬于化工品，本身對皮膚有一些傷害。工人在進入清理，若感到身體不適，應(yīng)立即停止清理，以免發(fā)生意外。
The workers before entering the tank cleaning, must be equipped with safety rope, protective cover, boots and other protective measures. The admixture itself belongs to the chemical industry, and it has some harm to the skin itself. The workers are going to clean up, and if they feel ill, they should stop cleaning up immediately to avoid accidents.
4、儲罐清洗外加劑企業(yè)應(yīng)對商混站進行必要的提醒。
4, the admixture enterprises should make necessary reminding to the commercial and mixed stations.
外加劑企業(yè)在與攪拌站溝通外加劑使用注意事項時，需對商混站人員進行必要的外加劑安全培訓(xùn)，同時商混站在清理外加劑儲罐前也可以向外加劑供貨商咨詢，并尋求必要的幫助，避免意外發(fā)生。
Admixture enterprises in the use of note and mixing station communication admixture, the mixing station personnel necessary additive safety training, at the same time mixing station in the cleaning tank before the admixture can be outside additive supplier consultation, and seek the necessary help to avoid accidents.
