Wear rubber gloves and cover cuts, grazes etc. with waterproof dressings. If a very large spill is involved, wear rubber boots. If it is likely that you might get splashed while cleaning up, wear a disposable plastic apron over a protective overall. Cover the spill with paper towels and gently flood the area with Premiere Products Liquid Bleach, diluted 1 part bleach to 4 parts water. If there is blood on the rubber gloves, wipe off with paper towels soaked in bleach diluted as above.
Place towels into a clinical waste bag.
Rinse the rubber gloves thoroughly, remove and allow to dry. Wash hands thoroughly. Any blood-stained clothing should be handled with care, and placed in a plastic bag for safe storage and transportation for laundering. Wash the area with water and detergent, and allow to dry. Note that if a spillage of urine is treated with bleach, toxic chlorine gas may be produced and you must ventilate the area.
