Take care not to slip in the bath. Surfaces that have been in contact with the product should be cleaned with a proprietary detergent. Keep out of the sight and reach of children. For external use only.

Instruct patients not to smoke or go near naked flames - risk of severe burns. Fabric (clothing, bedding, dressings etc) that has been in contact with this product burns more easily and is a serious fire hazard. Washing clothing and bedding may reduce product build-up but not totally remove it.
