Although nonflammable, it is a powerful oxidizing agent that can cause spontaneous combustion when it comes in contact with organic material.

When should you not use hydrogen peroxide?

Is hydrogen peroxide safe?

Because hydrogen peroxide is rapidly decomposed in the body, it is unlikely to cause chronic toxicity. However, repeated exposures to hydrogen peroxide vapor may cause chronic irritation of the respiratory tract and partial or complete lung collapse.

What does hydrogen peroxide do to the blood?

When a solution of hydrogen peroxide is added to human blood the peroxide is decomposed and oxygen is evolved. This reaction has been used to oxygenate stored blood before transfusion (Nikitin, 1948).

Is Neosporin or Vaseline better for cuts?
