Can You Mix Lysol and Bleach?

The answer is NO! Mixing Lysol and bleach is a dangerous combination because it creates a toxic gas called chloramine. This gas can cause a range of health problems, including:

  1. Respiratory issues: Chloramine can irritate the nose, throat, and lungs, causing coughing, wheezing, and difficulty breathing. In severe cases, it can lead to bronchitis or pneumonia.
  2. Eye and skin irritation: Chloramine can also irritate the eyes and skin, causing redness, itching, and burning.
  3. Nausea and vomiting: Inhaling chloramine can cause nausea, vomiting, and stomach pain.

These symptoms can be especially dangerous for people with pre-existing respiratory conditions, such as asthma or COPD. In severe cases, exposure to chloramine can even be fatal.

What Happens When You Mix Lysol and Bleach?

When you mix Lysol and bleach, the bleach reacts with the hydrogen peroxide in the Lysol to create chlorine gas. This gas then reacts with the ammonia in the Lysol to produce chloramine. The chemical reaction happens quickly, and the gas can fill a room in just a few minutes.

The danger of this gas is that it’s heavier than air, which means it can sink to the floor and accumulate in low-lying areas, such as basements or bathrooms. This can make it even more dangerous because people may not realize they’re being exposed to it until it’s too late.

What are the Symptoms of Exposure to Chlorine Gas?

Exposure to chlorine gas can cause a variety of symptoms, including:

  1. Coughing and wheezing
  2. Chest pain and tightness
