Etching is the process of cutting into parts of a metal surface in order to create a design in the metal. Etching traditionally uses strong acids or mordants in order to perform this function, although there are a number of modern processes that also use photo etching and electrical etching procedures. There are a number of important safety considerations for anyone involved in any kind of etching process, either in small fabrication houses of large factory environments. In traditional pure etching, a metal is covered with a waxy ground which is used because it is resistant to acid. While a number of metals can be used, the most common are copper, zinc, and steel. It is important to be trained in this process before you get involved, as whether you are working with acid or other chemicals, it is important to know what you are doing.

The modern use of steel etching has a number of differences when compared to the traditional method, with advances in materials, tools, and methods of working. Most large scale etching in the 21st century also takes place in dedicated etching and fabrication factories, so more emphasis is placed on worker safety. In a standard etching process, an acid resist, also known as a ground, is applied to a metal plate. The ground is hardened using heat, which is where much of the danger exists. Dedicated safety equipment and tools are required for steel etching, especially when dangerous acids and chemicals are used.

The modern process of photo etching has been around since the 1960s, where it was developed in response to the birth of the printed circuit board industry. In a standard photo chemical etching or milling procedure, light is projected onto the steel plate as a negative image exposes it. In many ways, photo chemical etching is not as dangerous as traditional etching due to the lack of heat, however there are a number of other dangers involved. Chemical etching needs to interact with photo chemicals, many of which are dangerous if they come into contact with your skin. No matter how you look at it, etching steel can be a dangerous process, and a number of safety steps need to be enforced to ensure a safe and secure fabrication environment.
