Polyaluminium Chloride
Polyaluminium Chloride or PAC is a chemical that is not harmful to health. It has good water solubility, is basic and has a positive electrical charge, thus it has high binding properties and very stable. It is popularly used in water production and treatment processes as a sedimentation catalyst. It is effective in both raw water and wastewater to increase water efficiency.
Caution
Inhalation Move the victim to fresh air and keep them in a position comfortable for breathing. If symptoms worsen, Get medical attention.
Skin contact Remove contaminated clothing and shoes immediately. Flush with warm water for 15 minutes. If the contaminated area is extensive, pour water over clothing and body. If skin irritation occurs, Get medical attention.
Eye contact Flush eyes with plenty of water, holding the eyelids wide open for at least 15 minutes, Get medical attention.
Ingestion Rinse mouth with clean water and drink plenty of water. Do not induce vomiting. Get medical attention.
Storage
Keep tightly closed and store in a dry place. During historical period, good ventilation is the main source of ignition and heat in storage 15 ๐C – 20 ๐C
