If need be, you can use slippers inside the kitchen. They should be reserved for the kitchen and must not be used for going to restroom (bathroom), or out of the Langar hall. Rather than using a leather product, some prefer rubber or plastic footwear. Anything used, should be reserved only for the kitchen.
Do not go to Langar and do no cooking with common cold, cough, fever, loose motions, motions with cramps, or with any other infectious disease like mumps, chickenpox etc. Do not cook with injury, ulcer, boil, or eczema on the hands. For a cough or sneeze, cover your mouth and nose with a napkin, look away from food and try to get away from it, dispose off napkin, and wash your hands with soap and water.
