Beta Tools Cu-Be Sparkproof Tools Information

Beta Tools Cu-Be Sparkproof Tools Information
Beta Tools Cu-Be Sparkproof Tools Warning

The ATEX 137 Directive 99/92/EC (European equivalent to the US OSHA "HAZLOC" standard) defines types, or Zones, of explosion risks in the workplace. It also outlines requirements for minimizing the risk of ignition in these potentially explosive environmets. For example, tools used in these Zones must not give off sparks if accidentally dropped on a concrete floor.

The Beta Tools line of sparkproof tools are manufactured of a special copper-beryllium alloy (Cu-Be) to meet 99/92/EC. Beta sparkproof tools are certified by BAM (independent German testing labs) to meet the ATEX requirements for use in the most hazardous Zones 0 and 20.

Classification of Areas Subject to Explosion Risk
ATEXHigh Medium-Low Extremely Low
Gases Zone 0 Zone 1 Zone 2
An area in which an explosive atmosphere consisting of a mixture of air and flammable substances in the form of gas, vapour or mist is continuously present or present for long periods or frequently. An area in which an explosive atmosphere consisting of a mixture of air and flammable substances in the form of gas, vapour or mist is likely to occur in normal operation. An area in which an explosive atmosphere consisting of a mixture of air and flammable substances in the form of gas, vapour or mist is not likely to occur in normal operation but, if it does occur, will persist for a short period only.
Dusts Zone 20 Zone 21 Zone 22
An area in which an explosive atmosphere in the form of a cloud of combustible dust in air is continuously present or present for long periods or frequently. An area in which an explosive atmosphere in the form of a cloud of combustible dust in air is likely to occur in normal operation occasionally. An area in which an explosive atmosphere in the form of a cloud of combustible dust in air is not likely to occur in normal operation but, if it does occur, will persist for a short period only.

Cu-Be alloy is also antimagnetic and corrosion-resistant, but its mechanical characteristics are different than those of steel. You must take care not to abuse or overload the tool.
