When handling caustic chemicals used in drain cleaners, it is important to wear protective gear such as gloves, goggles, and a mask to prevent skin and eye contact. Work in a well-ventilated area to avoid inhaling fumes. Always read and follow the manufacturer's instructions carefully, and never mix different chemicals together.
