Dangers of Mixing Cleaning Chemicals

Print a Sign-In Sheet | Spanish Version

Employees should be trained in the proper handling, use, and disposal of cleaning chemicals. Mixing cleaning chemicals can produce toxic gases such as chlorine, nitrogen trichloride, and hydrazine. Dangerous oxygen-free molecules can be released into the lungs. These molecules can be especially hazardous in small areas with little ventilation or air movement, such as bathrooms and closets. When inhaled, these gases may cause lung irritation, sore throat, headaches, breathing difficulty, and, when inhaled in large doses, even death. There is seldom a need to mix cleaning products as there are specialized chemicals and cleaning agents available for nearly every task.

The following guidelines should be followed to help ensure safety:

  • Do not mix any cleaning products, especially those containing bleach.
  • Train all employees about the dangers of mixing chemicals. Train them in accordance with OSHA’s Hazard Communication Standard regarding proper reading of SDS sheets, proper chemical & container labeling, proper disposal of chemicals, proper recognition of exposure symptoms, and proper treatment procedures for exposure.
  • If chlorine gas is accidentally released, evacuate the area until there has been sufficient time for ventilation. Do not re-open the area until the gas has been completely removed. If employees are involved in the cleanup of the chemicals, make sure they wear the proper personal protective equipment and properly dispose of the chemicals.
  • Always run clean water through a drain after flushing or rinsing cleaning products. This will help prevent the formation of toxic gases from chemicals that could potentially mix in the drain pipe.
  • When handling chemicals always follow the prescribed manufactures guidelines and utilize common sense to help protect yourself and others.
