* **Continuous Irrigation:** Continue flushing until medical professionals advise otherwise. In some cases, they may recommend continuing irrigation during transport to a medical facility.
**4. Identify the Chemical (If Possible):**
* **Check the Container:** If it is safe to do so, try to identify the chemical that caused the burn. This information will be valuable for medical personnel.
* **Do Not Attempt to Neutralize:** Avoid using neutralizing agents (such as acids to neutralize alkalis or vice versa) unless specifically instructed by medical professionals. These reactions can generate heat and worsen the burn.
**5. Cover the Burn:**
* **Sterile Dressing:** After flushing the area, cover the burn with a sterile, non-adhesive dressing. This will help protect the burn from infection and further irritation.
* **Loose Covering:** Avoid applying the dressing too tightly, as this can restrict blood flow.
* **Clean Cloth:** If a sterile dressing is not available, use a clean, lint-free cloth.
**6. Elevate the Affected Area:**
* **Reduce Swelling:** If possible, elevate the burned area to help reduce swelling and pain.
**7. Pain Management:**
* **Over-the-Counter Pain Relievers:** Mild to moderate pain can be managed with over-the-counter pain relievers such as acetaminophen (Tylenol) or ibuprofen (Advil, Motrin).
* **Stronger Pain Medication:** For severe pain, medical professionals may prescribe stronger pain medication.
**8. Seek Medical Attention:**
* **When to Seek Help:** It is essential to seek medical attention for any chemical burn, especially if:
* The burn covers a large area of the body.
* The burn is deep or involves multiple layers of skin.
* The burn affects the face, eyes, hands, feet, or genitals.
* The victim is experiencing difficulty breathing or other systemic symptoms.
* The victim has a history of medical conditions, such as diabetes or a weakened immune system.
* The burn is caused by a highly toxic chemical.
* **Emergency Medical Services:** In severe cases, call emergency medical services (911 in the United States) immediately.
**Medical Treatment for Chemical Burns**
Medical treatment for chemical burns may include:
* **Further Irrigation:** Medical professionals may continue irrigating the burn with sterile saline solution.
* **Debridement:** Removal of dead or damaged tissue (debridement) to promote healing and prevent infection.
* **Topical Antibiotics:** Application of topical antibiotics to prevent or treat infection.
* **Pain Management:** Prescription of stronger pain medication if necessary.
* **Wound Dressings:** Application of specialized wound dressings to promote healing.
* **Skin Grafting:** In severe cases, skin grafting may be necessary to cover large or deep burns.
* **Intravenous Fluids:** Administration of intravenous fluids to maintain hydration and electrolyte balance.
* **Monitoring for Complications:** Monitoring for complications such as infection, shock, and respiratory distress.
**Long-Term Care and Rehabilitation**
After the initial treatment, long-term care and rehabilitation may be necessary to promote healing and restore function. This may include:
* **Physical Therapy:** To improve range of motion, strength, and function of the affected area.
* **Occupational Therapy:** To help the individual regain skills necessary for daily living and work.
