Handling flammable liquids, explosion protection measures
During the handling, storage and dispensing of substances which can create an explosive atmosphere, the
requirements of ATEX Directive 94/9/EC and 1999/92/EC must be observed in addition to the 11th
Machinery Safety Law (GSGV) and the Industrial Safety Regulations (BetrSichV). Depending on the Ex-
zone, suitable protective measures are to be taken. Emphasis must be laid on preventing a build-up of
explosive atmosphere by altering the concentration (eg ensuring sufficient ventilation), operating conditions,
and constructive organisation (eg using suitable and approved containers, suitable storage facilities).
It must be ensured that sources of ignition caused by electrostatic charges are avoided by using electrical
equipotential bonding. Mechanically produced sparks must be avoided by using suitable tooling, transport
and loading equipment for example. Thermal ignition sources must be avoided by using suitable techniques,
prevention of friction, lightening protection, and the prohibition of open flames, open lights and smoking.
Organisational measures such as the identification of areas, implementation of warning signs and access
prevention for unauthorised personnel are required.
Equipment must be maintained in good condition, operated correctly and regularly inspected. Any necessary
repairs must be carried out immediately. Repairs which may affect the explosion protection of a piece of
equipment must only be carried out by the manufacturer.
Check that the coating on the load bearing parts of the drum lifter is in perfect condition. If corrosion is present,
the drum lifter may not be used.
Storage requirements as per TRGS 510 must be observed.
Electrical conductivity can be changed by the depositing of hindering substances and also by chemical and
mechanical influences in such a way that the permitted values laid down in the standards are exceeded. In
particular, dust, dirt and paint, acids and alkalis, overloads and impact loads can lead to the
discharge/conduction of electrical/electrostatic energy to the floor being reduced or completely interrupted.
The flooring in potentially explosive areas must be conductive and kept clean.
Because there are so many unknown factors affecting the use of our products, our guarantee with respect to
electrical conductivity relates exclusively to compliance with the permitted values laid down in the standards for
the wheels in new condition on delivery.
The user must ensure constant observation of technical safety regulations such as compliance with the values
for electrical conductivity in use. Check effectiveness at regular intervals.
9.3 Operation
in addition to section 7. For the "Operation" of Ex version equipment, the following notes apply:
Before entering an Ex zone, check the rollers for dirt and foreign bodies and clean them if necessary.
When using the drum lifter in an Ex zone, only electrically conductive drums may be used. All objects which
come into contact with the drum lifter must be electrically conductive.
When picking up containers (eg a drum from a wooden pallet) consider any static discharge and the resulting
dangers. Suitable equipotential bonding must be ensured. Ensure TRBS 2153 is observed.
Move slowly up to the drum and lift it. Ensure you keep below a speed of 1m/sec (3.6km/h).
9.4 Maintenance and repair
in addition to section 8. For the "Maintenance and repair" of Ex version equipment, the following notes apply:
Change fittings only outside of the Ex zone, eg when fitting another drum gripper. This also applies to
maintenance, cleaning and adjustment operations,
Ensure the completeness and correct fitting of all mounting and safety equipment. Check this at regular
intervals.
Ensure the equipment remains clean, especially the wheels and rollers and do not paint it.
Regularly check the bearings and grease if necessary.
When replacing parts, only use DENIOS original replacement parts. Use of unsuitable parts will lead to a loss of
ATEX suitability.
