Polyurethane on Skin: First Aid & Safe Removal

Immediate First Aid for Polyurethane Skin Contact

1. Remove source – Gently wipe/brush off excess with dry cloth/paper towel. Do not rub or scratch (drives chemical deeper, increases irritation).
2. Wash thoroughly – Mild soap (e.g., Dove, Cetaphil) + lukewarm water. Rinse 5+ minutes. Avoid harsh solvents (acetone, mineral spirits) – they increase absorption.
3. Cool compress – Clean damp cloth or ice wrapped in towel; 15–20 min q2–3h for swelling/pain.
4. Moisturize – Fragrance-free barrier cream (Cerave, Vanicream, Aquaphor) after drying. Restores lipid barrier.
5. Monitor for infection – Increasing redness, warmth, pus, streaking → see clinician.
6. Eye/oral exposure: Flush eyes 15+ min with saline/water; rinse mouth, do not induce vomiting. Seek emergency care.

Polyurethane Types Matter

• Uncured (wet) resin/isocyanate – Highly irritating, sensitizing; risk of occupational asthma, allergic contact dermatitis.
• Cured (solid) foam/coating – Inert; mechanical irritation only.

Occupational Setting

• Wear nitrile gloves (not latex – permeable), long sleeves, goggles.
• Use ventilation / PAPR for spray foam.
• Follow SDS; report exposures to occupational health.

Most incidental skin contact resolves with prompt washing. Persistent symptoms = medical evaluation.
