When must an ambulance, resuscitation area and equipment be ritually cleansed with soil after treating a patient injured by a pork grinding machine, and how is it done?

Summary

The obligation of ritual cleansing with soil arises when it is known with certainty, through sight, smell or taste, that pork impurity has transferred to otherwise clean places or equipment. If the transfer is unclear because of the urgency of treating the patient, the matter reverts to the original ruling, either clean or impure due to another source such as the patient's blood. Where doubt exists and one wishes to remove it, washing the suspected area with water without soil is sufficient. The Shafi'i and Hanbali scholars require soil together with water once pork impurity is truly confirmed.
