Information on gas

Here are gathered attributes of different hazardous gases encountered in industries, their different detection means (portable gas detectors or fixed systems) and well-suited respiratory protective equipment (gas mask or self-contained breathing apparatus).

information on gas and chemico-physical characteristics

A gas is conventionally defined as a substance without any proper shape or volume. Thus, gas properties and chemical features vary from one gas to another. Almost every industry or field of activity produce or use specific gas. These gases have to be known in order to get proper detection systems and protection from their dangerous effects.
