Technical Code for Safety of
High Altitude Operation of Building Construction
I General Provision
1.0.1 The standard is established for implementing the guideline of safety production in
high altitude operation during building construction, and for realizing definite safety
requirement, reasonable technique and economic applicability.
1.0.2 The standard is applicable to high altitude operations such as edge-near, hole,
climbing, hanging, operating platform and cross operations during the industrial and
civil building construction, and normal structures construction.
The standard is also applicable to others engineering construction needing high altitude
operations on all classes of hole, excavation, gutter, tank and so on.
1.0.3 So called high altitude operation in this standard should meet specifications "do
operation on the position where is 2 m (including 2 m)above the falling height base
level and it has falling possibility" specified by national standard "Classification of
Works at Heights" GB 3608-83.
1.0.4 High altitude operation should meet specifications related to relative national high
altitude operation and safety technique standard, besides this standard.
II General Rules
2.0.1 Technical safety measures and required materials and tools shall be listed in the
organization design of the engineering construction.
2.0.2 The a person in charge of the construction should preside over safety techniques
for high altitude operation in the engineering, and the corresponding responsibility
system should be established.
Gradual safety technique education and disclosure should be carried out before the
construction, and all technical safety measures process ands personnel protection items
should be put into effect. The construction shall not be processed without full
implementation.
2.0.3 Safety marks, tools, instruments, electric utility and all sorts of implements shall
be inspected, and they could be used after their sound condition is confirmed.
III Safety Protection for Edge-near and Opening Operation
3.1 Edge-near Operation
3.1.1 Protective measures should be taken for edge-near high altitude operation, and
should correspond with following specifications.
1 Guard rails should be emplaced at foundation trench periphery, at verandas that are
not emplaced with handrail or fence, material platform and raising platform periphery,
at non-external-falsework roofing and floor periphery and at water tank and water tower
periphery.
2. Safety protection net should be erected at the periphery of which second floor that its
first floor wall height exceed 3.2 m and at periphery which floor height exceed 3.2 m
without falsework.
3. Temporary guardrails should be emplaced for staircase heads staircase side in
flooring construction. Staircase head at top floor should be emplaced formal guard rails
with engineering structure process.
4. Guardrails should be emplaced on passages between headframe and construction
elevator, and falsework and building. Safety protection shed should be emplaced at
upper position of ground passage. the middle of double-cage headframe passage should
be separated and sealed.
5. For all sorts of vertical material receiving platforms, platform head should be
emplaced with safety gates or movable guard rails as well as guardrails on both sides.
3.1.2 Specifications and jointing requirements for edge-near guard rails members should
correspond with following specifications.
The little end effective diameter of bamboo rail should not be less than 70 mm. the
baluster tip diameter should not be less than 80 mm. steel wire which level is not less
than 16 should be used for binding balusters and binding circle number should not be
less than 3. there should be no slip in binding.
2. The upper bar top diameter of rough lumber rail should not be less than 70 mm. the
lower bar top diameter should not be less than 60 mm. and the baluster top diameter
should not be less than 75 mm. Wire nail with corresponding length should be used for
clenching or galvanized wire which level is not less than 12 should be used for banding,
and the surface should be smooth and steady.
3. The upper bar diameter of steel bar rail should not be less than 16mm, the lower bar
diameter should not be less than 14 mm. the baluster diameter should not be less than 18
mm. electric welding or galvanized wire should be used for fixing.
5. In case the external side of the edge are facing street, whole closing treatments such
as emplacing safety net and others reliable measures should be taken besides guard rails
are adopted.
3.1.4 Mechanics calculation and structural style of edge-near guard rails are detailed in
Annex 2.
3.2 Opening operation
3.2.1 When opening operation is taken ,or others high altitude operations are taken at
opening where there are person or object falling hazard or personal safety hazard
because of project and procedure requirement, safeguard devices should be emplaced
according to following specifications.
