If your hands come into contact with mercury in small amounts and your skin is not broken, it is usually not important and you should rinse with water immediately. However, if the skin is broken or a large amount of mercury has come into contact with your hands, it is recommended that you go to the hospital in time to avoid mercury poisoning. If the hand lightly touches the mercury and there is no skin breakage, it usually does not matter. The patient should immediately rinse any residual mercury on the hands with soapy water or water, and open a window to ventilate the area and maintain air convection. However, if the mercury has come into contact with the hand in large quantities and there is still a break left on the hand, then this should be treated in the hospital immediately. Otherwise, mercury entering the bloodstream can lead to mercury poisoning conditions such as itchy skin, red rashes, and numbness in the limbs. Hands in contact with mercury, if there is no skin breakage, it is recommended that the patient first observation, but if there is discomfort promptly go to the hospital.
