My working environment is a water treatment plant. I usually come into contact with flocculants (polyaluminum chloride), sodium hydroxide, hydrochloric acid, sodium chlorate and so on. Is it harmful to my health? Flocculants have no direct harm to human health. I accidentally spilled it on my hand when I was doing an experiment at school. The rest should be well protected. People with volatility had better wear masks, gloves and other basic labor protection articles. After the first feeding, it is ventilated outside, and the greening of water plants is generally good. There are some special things that need special attention, and the unit will have training. You should pay attention to listening and learning.
