Fresh (wet) concrete is highly alkaline and can cause skin irritation, severe third degree chemical burns and serious eye damage. Always wear protective gloves and glasses or goggles when working with wet concrete. Waterproof boots must also be worn if standing or walking in wet concrete. If clothing becomes contaminated with wet concrete, it should be removed at once and the affected body area(s) washed immediately. Flush eyes with clean water immediately after contact. Seek medical attention if you have persistent or severe discomfort.
