Non-sparking tools for working in places where sparks mean a potential danger of explosion. Where fire requires a special protection. Due to their magnetic features conventional steel tools are not suitable to be used in potentially explosive environments as explosive atmospheres or ignition sources can occur.

For this reason Elora offers the “Non Sparking” product range which follows the ATEX guidelines 94/9/EG (“ATEX 95”) providing requirements for the use of equipment in potentially explosive environments. These guidelines form the basic regulations for the safety of employees during installation, operation and maintenance of potentially explosive facilities. Depending on their risk of explosion the ATEX guidelines distinguish six risk zones:

For areas that are potentially explosive due to flammable gases, vapors or mist, the following zones shall apply: For areas thar are potentially explosive due to combustible dusts, the following areas shall apply:
Zone 0
Explosive atmospheres caused by mixtures of air and gases, vapours or mists are highly likely to occur and are present continuously, for long periods of time or frequently.
Zone 20
Explosive atmospheres caused by mixtures of air and flammable dusts are highly likely to occur and are present continuously, for long periods of time or frequently
Zone 1
Explosive atmospheres caused by mixtures of air and gases, vapours or mists are likely to occur.
Zone 21
Explosive atmospheres caused by mixtures of air and flammable dusts are likely to occur.
Zone 2
Explosive atmospheres caused by mixtures of air and gases, vapours or mists are unlikely to occur and if they do occur, do so infrequently and for a short period of time only.
Zone 22
Explosive atmospheres caused by mixtures of air and flammable dusts are unlikely to occur and if they do occur, do so infrequently and for a short period of time only.

Special non-iron alloys

Non sparking tools are made of non-iron alloys (e.g. Beryllium-Copper or Aluminium – Bronze). These alloys are antimagnetic, non sparking and very corrosion-resistant. The chemical composition of the material as well as the way of heating, the accuracy of the casting moulds and a controlled solidification process determine the quality of the non sparking tools.

Property Application or Benefits
Non-sparking Appropriate for explosive potential environments such as oil and gas works, petro-chemical plants.
Non-magnetic safety Essential for equipments that require complete non-magnetic safety.
Corrosion resistant Specially well suited for applications in corrosive environments like
encountered in marine works or fire-fighting applications.
Forged after casting Provides higher mechanical properties and better finishing.

Application remarks:

  • Non sparking tools are softer than usual tools.
  • The operation with these tools has to be carried out with accuracy and care.
  • Overstraining has to be prevented.
  • Only using non sparking tools as a protection measure in fi e endangered and explosion endangered areas is not enough. Please consider the instructions of local health and safety regulations for the protection of employees and accommodation.

Reworking:

  • Technical marking sheets are available on request for reworking (e.g. re-sharpen).

Applications Aluminium-Bronze/Beryllium-Copper

  • Chemical industries
  • Petro refine ies
  • Oil and gas carriages
  • Pipeline business
  • Drilling platforms
  • Fuel service (cleaning etc.)
  • Gas and electricity works
  • Varnishing
  • Federal armed forces, army
  • Civil defence and civil protection
  • Fire department
  • You can use it on all places where sparks create potential danger of explosion and fi e. For the activities which require the use (application) of a hundred percent non-magnetic and extremely rustproof tools.

How to apply non-sparking tools correctly

Non sparking tools are softer than conventional tools so that they should be used with special caution and care. Overstraining is to be avoided. In case non sparking tools have to be reworked technical instructions can be provided on request. Please consider that the use of non sparking tools as a sole means of protection in explosive environments is not sufficient. For best possible protection of employers and equipment legal and corporate regulations have to be observed.
