If you sustain a burn from a chemical, accident, or another incident, your first step is to receive proper medical care. Emergency personnel may need to be called immediately to provide guidance or direct assistance. Burns must be handled with the utmost care to prevent unwanted worsening of the injury. For example, it is not advisable to apply ice or very cold water to a burn. Oils and ointments should also be avoided. For appropriate guidance, call 911 if necessary.
