You will need to wear a respirator mask to protect your lungs. If you inhale the fumes it can cause pneumonia or even death. Try to keep the area as ventilated as possible by opening all windows.

If you have some leftover and need to store it, be sure to store it up high away from children and pets. Caustic soda is highly effective for unblocking drains when used properly, but safety precautions are imperative.
