Is it harmful to human health to use quicklime in a room for moisture absorption?

Placing quicklime in a room for moisture absorption can be harmful to the human body. Safety precautions must be taken when using quicklime for dehumidification, as improper use may adversely affect health, including exposure through the respiratory tract, skin contact, or eye contact.

If quicklime dust is inhaled, leave the area immediately and go to a place with fresh air. If symptoms such as difficulty breathing, coughing, or chest tightness occur, seek medical attention promptly. If quicklime comes into contact with the eyes, immediately flush them thoroughly with large amounts of water for at least 15 minutes, then seek medical help without delay. During rinsing, gently rubbing the eyes may help remove foreign particles.

If quicklime contacts the skin, immediately rinse the area with abundant water. Avoid using soap or other chemicals. If symptoms such as redness, swelling, or pain develop, apply anti-inflammatory and analgesic ointments—such as erythromycin ointment or olive oil—as directed by a physician.

In addition, it is important to note that if severe symptoms occur after exposure to quicklime—such as extensive skin burns or serious eye irritation—immediate medical treatment is necessary to prevent delays in care. Furthermore, when handling quicklime, always take safety precautions to avoid contact with the skin, eyes, and respiratory system.
