WebSep 19, 2024 · Oxidizers are solids, liquids, or gases that react readily with most organic material or reducing agents with no energy input. Oxidizers are a severe fire hazard. They are not necessarily combustible, but they can intensify combustion and increase the flammable range for chemicals so they ignite more readily.

WebThe term reducing atmosphere is used for atmospheres including reducing gases , such as hydrogen, and can also include gases that are neither reducing nor oxidizing, such as carbon dioxide . The term has also come to include gas mixtures with no reducing gases, as long as no oxidizing gases are present. WebCare must be used when using an oxidizing or a reducing agent. The reaction can often be violent, or cause unexpected results or toxic gases. For example, many of the oxidizing agents can liberate chlorine from hydrochloric acid, and can cause large flames when mixed with glycerin. Conversely, a reducing agent like sodium thiosulfate is useful ...
