Beta Tools sparkproof tools are constructed of a special copper-beryllium (Cu-Be) alloy for safe use in potenially explosive environments.  Beta Tools Cu-Be tools are certified non-sparking under European Directive 99/92/EC.  They are also perfectly antimagnetic and corrosion-resistant.

Note 1: Copper-beryllium tools are not safe for use in contact with acetylene. Acetylene can react with the copper to form copper acetylide, a powerful and very dangerous explosive. 
Note 2: This 55mm/60mm size is not a standard production item and is not immediately available from stock.  Beta Tools will only manufacture this size on request.  Lead times depend on the surrounding production schedule.
