Depending on the test needed, the urine collection container may have a chemical inside to preserve the substance to be tested. If so, the name of the chemical will be on the container. If you or another member of your family should accidentally come in contact with the preservative, take the following actions. Because there is some hazard associated with these chemicals, keep the container out of the reach of children. The risk of injury from the chemical decreases as the container becomes filled with urine.


Boric acid, hydrochloric acid, and sodium carbonate can irritate your skin and could be harmful to your eye. If swallowed, they could damage your esophagus or stomach. If you breathe in dust or fumes, they could be harmful to your lungs. Hydrochloric acid can also be absorbed through your skin.


  •  If you spill a powder (boric acid or sodium carbonate), sweep it up, discard into the trash and mop the area with water.
  • If you spill a liquid (hydrochloric acid), wear rubber gloves and cover the spill with baking soda. Mix until there is no more bubbling, then mop up with water and discard down the drain. If baking soda is not available, mop up with water and then rinse the area thoroughly with water. Run water for five minutes after discarding down the drain.
  • If you get any chemical on your skin, rinse well with tap water to remove it. Remove any contaminated clothing and rinse well with water. DO NOT add baking soda to hydrochloric acid on the skin or in the eye.
  • If you splash chemical into your eye, rinse the eye with cool tap water for 15 minutes. Try to hold the upper and lower eyelid open while rinsing. Have the eye checked by a physician.
  • If you breathe in dust or fumes, move to an area with fresh air. If breathing is difficult, seek medical attention.
  • If a family member swallows any chemical, take the following actions and seek medical attention immediately:
    • Boric Acid: Induce vomiting. If the victim is conscious, give 2-4 cupfuls of milk or water.
    • Hydrochloric Acid: DO NOT induce vomiting. If the victim is conscious, give 2-4 cupfuls of milk or water.
    • Sodium Carbonate: DO NOT induce vomiting. If the victim is conscious, give large quantities of water.
