Before Passover, MDA receives the highest number of calls for injuries related to cleaning agents. A reaction of cleaning agents or inhalation of the vapors of the created substance may cause a burn, irritation, or damage to the skin.
The most common mistake of all is mixing zero acids to clean toilets with bleach, which can cause irreversible damage if you accidentally inhale the gas vapors into your lungs. The cleaning agents, especially the concentrated ones, such as unclogging liquids or other substances that contain caustic soda (sodium hydroxide), are very flammable, and any small spark of fire can ignite them and the surfaces they are on. Do not smoke while cleaning, a mistake that can be costly. Don't mix VINEGAR WITH CLEANING AGENTS, as the combination creates a very dangerous chlorine gas, which is already very dangerous. Do NOT use cleaning products that contain degreasers, substances to open sewer clogs, concentrated bleach, or certain pesticides.
