Final answer:
Alkaline burns should be irrigated for at least 20 minutes according to the hazardous materials standard to effectively dilute and remove the substance, thus reducing tissue damage and aiding in the healing process.
Step-by-step explanation:
Alkaline burns should be irrigated for at least 20 minutes according to the hazardous materials standard to effectively dilute and remove the substance, thus reducing tissue damage and aiding in the healing process.According to the hazardous materials standard, it is recommended to irrigate an alkaline burn for at least 20 minutes. This is because alkaline substances can continue to cause damage to the skin and underlying tissues for a significant period after contact, and it is crucial to dilute and remove the alkaline agent as thoroughly as possible. Proper irrigation is a critical first-aid measure that can significantly reduce the extent of injury and aid in the healing process.
