When a chemical enters the eye or contacts the skin, acting calmly and promptly reduces damage and improves outcomes. Begin by removing the source of exposure and avoiding any further contact with contaminated surfaces. For eye splashes, immediately rinse with lukewarm water or sterile saline, keeping the eyelids open to irrigate thoroughly. If multiple chemicals are involved, identify the substance if possible, as some require specific procedures or antidotes later. Do not rub the eyes, apply ointments, or delay rinsing to seek bandages or home remedies. Aim to flush continuously for several minutes, then reassess the situation and prepare for professional assistance.

Skin exposure requires rapid irrigation of the affected area to dilute and wash away irritants. Begin by removing contaminated clothing and jewelry carefully, taking care not to spread the chemical to other areas. Flush the skin with plenty of clean water for at least 15 minutes, using a gentle flow that avoids further tissue damage. If you have access to a mild soap, you can wash the surrounding skin after an initial rinse, but avoid harsh scrubbing. Do not neutralize acids or bases with household chemicals, as this can worsen injury. After rinsing, cover the area with clean, non-adherent dressings and seek medical evaluation as soon as possible.

Eye injuries from chemicals can progress quickly, making time critical. Continue eye irrigation with a steady stream of clean water or saline. If available, use eye wash stations or portable bottles designed for ocular irrigation, ensuring the flow reaches under the upper and lower lids. Do not attempt to neutralize by applying baking soda, vinegar, or other agents to the eye. After several minutes, check for persistent redness, burning, blurred vision, tearing, or light sensitivity. If pain worsens, or if vision is compromised, avoid placing pressure on the eye and arrange emergency transport. Monitoring and documentation of symptoms aids subsequent medical care.

Skin injuries from caustic chemicals may involve burning sensations, redness, swelling, or blistering. After flushing, inspect the area for signs of deeper tissue damage such as pale, white, or gray skin, or excessive tenderness. If the chemical is petroleum-based, avoid using oily products to remove residues; instead, continue rinsing with water. For aqueous solutions, water remains the primary agent. Remove contaminated clothing carefully, and do not reuse fabrics that were soaked with chemical substances. Cover the affected skin with a clean dressing to minimize infection risk and prevent further contact. Seek medical evaluation promptly to determine the need for specialized treatment.

Exposure incidents often occur in workplaces, homes, or during chemistry activities. A swift, methodical response reduces the likelihood of long-term injury. If exposure is confined to one area, continue flushing while you observe for evolving symptoms such as increasing pain, swelling, or changes in sensation. For eye splashes, keeping the head tilted slightly toward the affected side can aid drainage. If a chemical splashes both eyes, perform simultaneous irrigation while keeping the patient comfortable and still. Maintain a calm environment to prevent premature movement, which could worsen irritation. After initial cleansing, seek professional help and follow any recommended clinical steps.

Medical evaluation after a chemical splash considers the substance, concentration, exposure duration, and affected tissue. Provide clinicians with as much information as possible about the chemical's identity and the sequence of events. Note whether the exposure was dermal, ocular, or both, and document any immediate symptoms such as burning, tearing, redness, or numbness. Some agents may require antidotes, eye drops, or antibiotic protection to prevent infection. Even if symptoms lessen after rinsing, internal damage can still be present. Do not rely on home remedies or delays; professional assessment helps prevent complications and promotes safer recovery.

After initial care, continuing observation is essential because symptoms can evolve. Take note of any changes in vision, sensation, or skin integrity over the first 24 hours. If vision remains blurry, if light sensitivity worsens, or if there is persistent discharge, seek urgent medical attention. Similarly, if skin redness expands beyond the initial area, or if blistering develops, arrange medical care promptly. While awaiting help, avoid applying ointments, perfumes, or other topical products that could interfere with assessment. Keep the patient comfortable, protect the eye from bright light, and maintain a clean, dry environment to prevent secondary infection.

During transport to care facilities, communicate clearly with responders about exposure details. Mention the chemical’s approximate concentration, whether it was acidic or basic, and any previous eye or skin conditions that could influence treatment. If contact with a chemical occurred in a workplace, inform supervisors and safety officers as appropriate. While en route, avoid giving beverages or food, especially if the patient is dizzy or nauseated. Remain within arm’s reach of the patient to provide reassurance and to monitor for signs of distress. Upon arrival, hand over the complete exposure history to the medical team for rapid triage.

For eye exposures, continuing irrigation during transport helps minimize residual chemical exposure. If the patient can tolerate it, maintain a gentle flow of saline and inspect the eyes periodically for persistent irritation or growing redness. Do not let the patient rub the eyes, which can increase tissue damage. If eyelids are swollen, gently hold them apart during irrigation to ensure complete cleansing. In cases of chemical burns, the medical team may perform further assessment, imaging, or specialized eye drops. Early, thorough decontamination improves the likelihood of recovery and reduces the risk of long-term visual impairment.

For skin exposure, keeping the treated area clean and protected remains important on the way to care facilities. Ensure the dressing remains non-adherent and breathable to reduce pain during removal. Avoid recontaminating exposed skin by preventing contact with contaminated clothing or surfaces. If pain is significant, nonprescription analgesics may be used as directed by a clinician, but never before professional advice. In severe exposures, deep tissue injury can occur beneath seemingly intact skin, underscoring the need for thorough examination. Transportation logistics should consider patient comfort and rapid access to appropriate care.

Once medical teams assume care, they will reassess the exposure details, carried out rinsing history, and any residual chemical residues. Clinicians may perform eye irrigation with sterile solutions, administer numbing drops, or apply protective ointments as indicated. For skin injuries, they might remove contaminated debris, debride damaged tissue if necessary, and initiate antibiotic or anti-inflammatory regimens. The goal is to minimize tissue loss, prevent infection, and preserve function. Follow-up appointments, refractive assessments, and skin healing follow pathways will be explained, along with signs that require urgent re-evaluation.

After discharge, people should monitor healing progress at home and seek prompt care if new symptoms appear. Protect the affected eye from further trauma by wearing protective eyewear in risky environments. For skin, keep dressings clean and dry, and avoid sun exposure on healed areas to prevent discoloration. Maintain hydration and balanced nutrition to support tissue repair, and adhere to prescribed medications. If pain, vision changes, or skin color shifts occur, contact healthcare providers promptly. Education about chemical safety can reduce future exposure risks and improve readiness in emergencies.
