This procedure describes the accident prevention rules
and safety programs of Bina that shall apply to all
personnel engaged for the construction work of the PROJECT.
The primary purpose of this procedure is to prevent
accident, which may injure personnel or damage property.
2. SAFETY COMMITTEE
The Project Manager shall organize
a safety Committee Consist of Site Manager and Safety

by the construction safety rules and procedure. The
committee shall cover security and sanitation as well
as safety activities of the construction work and the
operation procedure shall be established prior to starting
the construction work.
3. GENERAL REQUIREMENT
All employees working on the
SITE shall wear as authorized temper proof badge on
their outer garment at all time within the SITE. This
badge shall show the registered number and category
of each work.
3.2. House Keeping
All construction office and temporary facility and work
area shall be kept reasonably clean and free of rubbish

18.104.22.168. Work Permits during
the Precommissioning of Plant
At certain stages of progress of a contract some areas
of a plant may be simultaneously occupied by several
interested groups of people.
They may be divided into three general categories, i.e.:
- Construction & Commissioning Supervision (Contractor)
- Construction Contractors.
- Employer's Operating Engineers (Employed).
In order to prevent dangerous situations arising through
the presence of persons working in these areas occupied
by Construction Contractor, by Employer Commissioning
personnel the responsibility for the safety of those
persons must be determined and agreed before the start
of the activity by al the parties concerned.
When the Commissioning Manager intend to carry out testing
or predommissioning or commission operations on the
plant, the responsibility for the area will be taken
over by the (designed) EMPOYER Area Manager who will
assume control of the area.
22.214.171.124. Procedure for the Issuance
of Work Permit:
The Commissioning Manager must advise the Site Manager
in writing that the plant or section of the plant (to

or commissioning work to be carried out in that area
is to be stated.
Immediately the Resident manager will issue a Circular
to all Parties and will inform Contractor Personnel,
Construction Contractor Representative and Employer's
Representative that no work is to be carried out in
that area unless authorized by the issue of a work permit,
at that moment the Employer Area Manager will assume
control of the area.
The Construction Contractor shall ask the Work Permit
for any work to be carried out on the "Controlled
The ISSUING AUTHORITY (Employer AREA MANAGER) will indicate
the particulars of the precautions to be observed, and
will sign the Work Permit.

responsibility to observe the prescribed precautions
and will start the work only after that all the prescribed
checking has been carried out including the checks by
the EMPLOYER fire Brigade.
Warning notices should be posted at the approach to
