2 GENERAL RULES
2.3.
General safety rules for the scaffolding assembly and use
2.3.1.
The employees hired for the scaffolding assembly and disassembly should be trained and authorised by a training
centre approved by the Institute of Mechanised Construction and Rock Mining in Warsaw.
2.3.2.
When assembling and disassembling the scaffolding you should use the personal protective equipment.
2.3.3.
When assembling and disassembling the scaffolding you should establish a danger zone and secure it with the
proper markings and railings min. 1,5 m high. The danger zone cannot be smaller than 1/10 of the scaffolding
height and not smaller than 6 m according to PN-M-47900-2:1996 section 4.10.4. In a city compact settlement
the danger zone may be smaller providing that other protections are used.
The scaffolding cannot be assembled, disassembled or used during:
a) sunset of no proper lighting has been provided;
b) heavy fog, rain, snow and glazed frost;
c) storm and wind that exceeds 10 m/s.
2.3.4.
The scaffolding assembly and disassembly area should be marked with the warning plates provided in the visible
locations at the height of 2.5 m from the ground level. The text on the plates should be readable at least from
10 m.
2.3.5.
The scaffoldings located directly at the circulation roads should be provided with the protective canopies which
comply with § 22 of the Regulation of Minister of Infrastructure of 6 February 2003, Journal of Laws No. 47 item
401.
2.3.6.
The frames located at the gates, clearances and passages used for the vehicle traffic should be protected with
the barriers (bumping posts) which are not connected with the scaffolding structure.
2.3.7.
When the passage is blocked during the scaffolding assembly (against the local authority consent) you should
place a barrier in the passage along with a red shield with a text that warns of the closed or blocked passage
and install a red light on the barrier that will be used at night.
2.3.8.
The scaffolding cannot be assembled, disassembled or used nearby the overhead power lines if the distance
between the scaffolding and the extreme power lines is smaller than:
a) 3 m for the lines with the maximum rated voltage of 1 kV;
b) 5 m for the lines with the rated voltage between 1 kV and 15 kV;
c) 10 m for the lines with the rated voltage between 15 kV and 30 kV;
d) 15 m for the lines with the rated voltage between 30 kV and 110 kV;
e) 30 m for the lines with the rated voltage exceeding 110 kV.
When the scaffolding is assembled or disassembled under the overhead power lines or at a distance smaller
than those specified above during the works the voltage should be cut-off.
2.3.9.
The scaffolding structure should be equipped with the lightning protection equipment according to PN-M-
47900-2:1996.
2.3.10.
The scaffolding may be used when it is accepted by the technical supervisor or other authorised person. During
the acceptance you should test the scaffolding according to section 7.3. of PN-M-47900-2:1996.
The scaffolding acceptance is confirmed with a log according to annex no. 1 to this manual or a record in the
construction logbook.
2.3.11.
The scaffolding should be provided with a plate which informs of the permissible platform load. It is prohibited
to load the scaffolding platforms with materials which are heavier than its load capacity and to gather people
on the platforms.
2.3.12.
The scaffolding may be equipped with a device used for transporting materials with the jibs secured to the
scaffolding structure. The jibs may be made of the pipes secured to the scaffolding with the couplings. You can
use the typical jib and block offered by the manufacturer.
Maximum weight of the lifted materials cannot exceed 150 kg. When using jibs with a higher lift capacity which
are secured to the scaffolding you should carry out the structural analyses for this scaffolding. The transport
jib must be additionally anchored at least in two points. Distance between the jibs cannot exceed 30 m. Distance
of the cumulative axis from the furthest scaffolding point on the lifting plane cannot exceed 0,5 m. Height from
the block attachment point to the platform level cannot be smaller than 1,6 m.
For vertical transport it is recommended to use the hoisting winches with attachment that can be installed on
the scaffolding. This equipment must have the approval certificate issued by the Office of Technical Inspection.
The hoisting winches should be installed in strict accordance with the manual prepared by the hoisting winch
manufacturer.
2.3.13.
Before each use the scaffolding should be checked for the proper and complete structure and you should also
