Mechanical Handling

Turner Explosion Protection Systems supply mechanical handling equipment (MHE) conversions for surface, mining and military applications, which comply to the essential health and safety requirements of the ATEX directive 94/9/EC and/or with the following standards:

• BS EN 1755:2000 Safety of industrial trucks - Operation in potentially explosive atmospheres - Use in flammable gas, vapour, mist and dust. for Forklifts.
• BS EN1834-1:2000 Reciprocating internal combustion engines - Safety requirements for design and construction of engines for use in potentially explosives atmospheres - Part1: Group II engines for use in flammable gas and vapour atmospheres.
• BS EN1834-2:2000 Reciprocating internal combustion engines - Safety requirements for design and construction of engines for use in potentially explosive atmospheres. Group I engines for use in underground workings susceptible to firedamp and/or combustible dust.
• BS EN1834-3:2000 Reciprocating internal combustion engines - Safety requirements for design and construction of engines for use in potentially explosive atmospheres. Group II engines for use in flammable dust atmospheres.
• MoD - JSP 482 July 2008, Chapter 16, Edition 3. Vehicles and mobile mechanical handling equipment (MHE) in explosives facilities.

When specifying a new piece of (civilian) MHE, the following questions need to be addressed:

• Equipment Group - I (mining) or II (surface).
• Area Classification - Zone 1 (gas), Zone 2 (gas), Zone 21 (dust), Zone 22 (dust) or Safe Area.
Refer to BS EN60079-10-1 (gas) and Refer to BS EN60079-10-2 (dust).
• Equipment Category - M2, 2G, 3G, 2D or 3D (derived from area classification).
• Gas Grouping (for gas atmospheres) - IIA, IIB or IIC.
Refer to EN 60079-20:2000.
• Dust Grouping (for dust atmospheres) - IIIA, IIIB or IIIC
Refer to EN61241 series.
• Temperature Class - T3 (200°C), T4 (135°C), etc.
Refer to EN 60079-20:2000 (gas) and EN61241 series (dust).

For military MHE, the following questions need to be addressed:

• Category of Potentially Explosive Site (PES) - Category A (gas), Category B (dust) or Category C (explosives).
• Area Classification - Zone 1 (gas), Zone 2 (gas), Zone 21 (dust) or Zone 22 (dust).
• Equipment Category - 2G, 3G, 2D or 3D.
• Gas Grouping (for gas atmospheres) - IIA, IIB or IIC.
• Dust Grouping (for dust atmospheres) - IIIA, IIIB or IIIC.
