 To prevent acid and alkali burns, use appropriate personal protective equipment (PPE) like gloves, eye protection, and lab coats when handling these substances. If a burn occurs, immediately flush the affected area with copious amounts of cool running water for at least 20 minutes, removing contaminated clothing and jewelry while doing so. Seek medical attention for severe burns, especially those involving eyes, face, hands, feet, or genitals. 

Detailed Precautions and First Aid:

1. Preventative Measures:

Wear PPE: Always wear appropriate PPE, including gloves, eye protection, and lab coats, when handling acids and alkalis.

Storage and Handling: Store chemicals properly and follow safety guidelines for handling, mixing, and disposing of them.

Spill Prevention: Ensure proper containment and spill clean-up procedures are in place. 

2. First Aid for Burns:

Immediate Flushing:

Water is Key: Immediately flush the affected area with a large amount of cool, running water for at least 20 minutes. This helps to dilute the chemical and prevent further damage. 

Eye Burns: If the burn is in the eye, hold the eye open and flush with water, or place the face in a bucket of water and blink hard to flush the eye. 

Contaminated Water: Be careful not to allow the contaminated water to flow onto other parts of the body or yourself. 

Remove Contaminated Items:

Clothing: Carefully remove any clothing, jewelry, or other items contaminated with the chemical. 

Dry Chemicals: If the chemical is a dry powder, brush it off with a clean brush before flushing with water. 

Seek Medical Attention:

Severe Burns: Seek immediate medical attention for severe burns, especially those involving the eyes, face, hands, feet, or genitals. 

Babies and Older Adults: Babies and older adults may require medical attention for even minor burns. 

Do Not:

Neutralize: Do not try to neutralize the burn with an acid or alkali, as this can worsen the burn. 

Apply Creams/Ointments: Do not apply any creams, ointments, or other substances to the burn, as this can interfere with treatment. 

3. Special Considerations:

Hydrofluoric Acid: For hydrofluoric acid burns, apply calcium gluconate gel every 15 minutes. 

Metal Alkalis: Burns involving elemental metals (lithium, potassium, sodium, magnesium) should not be flushed with water, as this can worsen the burn. Instead, cover the area with mineral oil. 

White Phosphorus: White phosphorus burns should be irrigated with water and kept wet with a moist bandage or petroleum jelly.
