During chemical liquid sterilization, which precaution is advised?

• A. It should be heated to 800°F
• B. It should be used without cleaning
• C. Do not contact skin
• D. It can be applied to skin

Answer: (C)

Chemical liquid sterilants are hazardous to skin, so the key precaution is to avoid contact with the skin. These solutions are often caustic or toxic, and touching them can cause chemical burns, irritation, or absorption leading to systemic effects. To stay safe, handle them with appropriate PPE and keep skin covered; never apply the sterilant to your skin. Heating to extreme temperatures is dangerous and not how these products are used; they are not supposed to be used at such temperatures. They should be used on properly cleaned items because residues or soil can shield microorganisms and reduce effectiveness. If skin contact occurs, rinse with plenty of running water immediately and seek medical advice if irritation persists.
