Units for operation in dust / air atmospheres
In areas, which are explosive by inflammable dusts, the surface temperature must not exceed
2/3 of the minimum ignition point in degrees Celsius (°C) of the dust/air mixture. Temperatures
of surfaces, which can be subject to dangerous deposits of ignitable dusts, must be one safety
margin lower than the minimum ignition temperature of the layer which can possibly be
generated by the respective dust. This requires a safety margin of 75 K between the minimum
ignition point of a dust deposit (ignition temperature) and the surface temperature of the unit. If
the dust deposit exceeds a thickness of 5 mm, larger safety margins are required. The
relevant key data of dusts can be called up via the GESTIS-STAUB-EX database at
www.dguv.de or taken from the HVBG/BIA report 12/97 "Combustion and explosion
characteristics of dusts" and be converted:
Starch / milk powder / gelatine
Ignition temperature 390°C x 2/3 = 260°C max. permissible surface temperature
Wood / grinding dust
Ignition temperature 290°C - 75°C = 215°C max. permissible surface temperature
Classification of the units
All important information for classification of the Yalelift series can be found in table 6 for
intended use in general industrial applications.
The documents have been checked by a nominated body (0035) and deposited at TÜV
Rheinland Industrie Service GmbH, Haumannplatz 4, D-45130 Essen, Germany.

ORMATION
Materials subject to danger of friction and impact
Individual sparks can be generated as a result of frictional and/or impact processes and, as a
consequence, can be the cause dangers of ignition in gases or impact-sensitive dusts.
Increased danger of ignition may emanate from clashing of special material pairings. These
are non corrosion-resistant steel or cast iron against magnesium or pertinent alloys. This
applies especially in case of rust (e.g. surface rust).
Especially at the friction points of the chain and load hook rust (surface rust) may occur.
For correct operation of the product it must therefore be ensured that there is no rust at these
wear points and that in the application area there are no material combinations of the above-
mentioned aluminium alloys and steel (exception: antirust steel) at possible friction, impact or
grinding points; thus spark formation by these material combinations as a result of mechanical
impact can be excluded.
