Is sulfur flammable?

Sulfur, a non-metallic element commonly found in nature, is not flammable under normal conditions.

This means that it will not ignite or catch fire spontaneously when exposed to a flame or spark. It is relatively unreactive and stable and does not easily react with other substances to produce a combustion reaction.

However, sulfur can be made to burn if it is heated to its ignition temperature or if it is mixed with other substances that are flammable. In these cases, sulfur can contribute to the combustion reaction and help sustain the fire.

It’s important to note that some forms of sulfur, such as sulfur dust, can be highly reactive and explosive if they are suspended in the air. This can occur if sulfur dust is generated during handling and processing operations. In these cases, special precautions must be taken to avoid dust explosions.

Overall, while sulfur itself is not flammable, it is important to handle it with care and to be aware of the conditions under which it can contribute to combustion.

Can sulfur ignite and cause a fire?
