Non-sparking tools are those that generate low energy sparks, always below the ignition limit of those dangerous substances (gas or dust) present in the environment. The tools are called “non-sparking” if the temperature of the sparks emitted is below the lower limit of ignition, and they are therefore safe for use in explosive atmospheres.
An explosive atmosphere is a mixture of flammable substances (whether in the form of gas, vapor, mist or dust) with air that, after ignition, lead to a combustion that spreads to the entire unburned mixture
