daily routines in our plants to our customers’ project worksites
and our actions in our neighboring communities. Our aspiration is
to conduct our business with zero harm to people. We believe in
visible leadership and personal accountability for Health and
Safety at all levels and throughout our organization.

To reach this aspiration, we are committed to:

• Maintain a global Health and Safety Management System designed to continuously

improve our performance and actively manage risk in our business.
• Drive for operational discipline by instilling a mindset of safe execution and follow-up.
• Communicate openly with all stakeholders on relevant health and safety issues.

c) Cladding of insulating layers shall be made of aluminum or galvanized steel
sheets of minimum thickness of respectively 0.75 mm or 0.63 mm. Profiled
sheets may be used on large process filters and large ductwork. Particular
attention to supports passing through cladding is required.

5.9 Wear Parts and Wear Protection

a) All Equipment exposed to wear, shall be protected by high wear resistant
materials of bolted replaceable design.
b) Special attention is needed for access to- and handling of replaceable liners.
The maximum weight and size for manual handling, as governed in the country
of project execution strictly applies, however it shall not exceed 25 kg per piece.

5.10 Vibration Prevention and Confinement

a) Machine vibrations are to be limited to acceptable levels by means of
decoupling of foundations (where necessary) and sturdy design of building
structures with due consideration of frequency / excitation aspects.
b) Drive trains of main machinery (i.e. kiln, mills, process fans and blowers) shall
be analyzed to ensure that operational speed do not coincide with natural
frequency.
c) Vibration sensors shall be provided for- and fitted to all Main Equipment
subjected to material build-ups. This includes gearboxes for vertical mills and
process fans.

5.11 Instrumentation tabs and mounting flange

Instrumentation tabs and mounting flanges as well as associated check and
calibration tabs for process control Equipment shall be installed latest during erection
in order to avoid damage to insulation and cladding after erection of the Plant.

6. ENVIRONMENTAL ASPECTS

6.1 Particulate Emissions and Controls

6.1.1 Nuisance Dust Collection

a) Dust collectors or dust suppression Equipment shall be provided wherever
needed, so that the Plant is visibly dust-free during operation. Related ductwork
and chutes shall be skillfully designed and executed, with provisions for
adjustment and fine-tuning. Particular attention shall be paid to the dedusting of:
• Transfer points of conveying Equipment
• Hoppers, bins, silos
• Dust producing machinery
b) The dust collector and suppression Equipment shall be designed to a clean air
dust load of less than 30 mg/Nm3 dry or according to Permits, whichever is
more stringent.
c) Venting ducts shall always be routed to the outside of buildings.

6.1.2 Process Dust Collection

The process dust collectors shall include the dust collectors for the kiln, the partial kiln
gas extraction (bypass), the clinker cooler and all mills, and shall be designed to have
a clean gas dust load less than 30 mg/Nm3 dry or according to Permits, whichever is
more stringent.

6.1.3 Particulate Emission Monitoring

In accordance with Permits, the stacks of process dust collectors shall have
continuous monitoring. Such stacks are equipped with correctly located and
dimensioned platforms.

6.3 Noise Emission

Noise emissions are to be kept to a minimum. Local and international limits shall
not be exceeded. The following applies:
At work places the maximum level shall be less than 85 dB(A) at one meter from
the emitting machine.
a) At the closest point of the nearest living area outside the Plant the maximum
level is 40 dB(A) at night and 55 dB(A) during the day (06:00 - 22:00).
b) Where possible noise emission levels shall be in accordance with ISO
standards 3744, 3746, 4871, 11201.

6.4 Evidence of Environmental Protection Measures

The Contractor shall provide a report with the final design of the Plant,
documenting all measures taken to comply with the environmental requirements
of the Permits.
