What safety precautions are needed when using POP?

When handling Plaster of Paris, safety is crucial because it reacts exothermically and can cause burns if misused. Always wear gloves, eye protection, and a dust mask to avoid irritation. Work in a well-ventilated area, since fine POP dust can irritate lungs and eyes. Never mix POP with bare hands directly in water—it can harden and trap skin, leading to burns. Avoid pouring leftover plaster down drains, as it solidifies and clogs pipes. Use disposable containers or rinse tools before the plaster begins setting. POP should never be applied directly to the skin for molding body parts because the heat released as it sets can cause injury. Keep materials out of reach of children unless supervised. Store the powder in a dry, airtight container to prevent premature hardening. Following these precautions ensures a safe, enjoyable crafting experience while maintaining material quality and user safety.
