PROJECT MANAGEMENT:
ERECTION OF STRUCTURALS AND EQUIPMENTS:
•
The work of
erection at Sites to be executed by qualified Riggers or under the supervision
of qualified and experienced Supervisors.
•
All Standing
and Running Rigging to be checked before use, during use and before
transferring the Load by other means for safety considerations.
•
Temporary
Structures are to be secured properly by standing rigging, guy ropes and stay
wires so that they do not fall accidentally.
•
The structure
to be checked thoroughly before transferring the load from Guy Wires, Stays and
Standing Rigging and after it is assured that the structure is sound enough to
take its own load, the temporary stays, guys and standing wires are removed
from the structure.
•
All Lifting appliances, Ropes, Wire Ropes, Blocks
and Tackles are to be load tested and utilized according to their lifting
capacity. Colour Code for indicating the Testing Status of the Slings to be
followed as per statutory norms and slings in RED Zone are to be used only after
proper checking and tested at the earliest opportunity.
•
It must be ensured that all material required for
the erection work is available at site with proper sequencing, labeling and
especially all fasteners are available beforehand.
•
The columns are to be erected only after
consolidation of foundation work and securing the columns with proper anchoring
bolts in the foundation.
•
Installation of cross beams, transverse beams,
longitudinal beams etc. are to be undertaken after the erection of columns and
securing the connecting brackets in place.
•
The erection sequence is to be pre-planned and this
sequence is to be followed for avoiding any mishap during the course of
erection.
•
All riggers and workers employed for the erection
work should be well conversant with the use of Personnel Protective Equipment
(PPE) i.e. Fall Arrestor Gear, Safety Belts, Life Lines, Load Transfer Lines
etc.
Hazards
with Slings:
Poor
condition:
•
Broken wires/strands
•
Corrosion/rust
•
Excessive wear
•
Severe
kinks/bends
Rules to Follow When Slinging and
Handling a Load:
•
Make sure that
the horizontal distance between the points of attachment of the load, does not
exceed the length of the slings.
•
This will
ensure that the angle between the two legs of the sling does not exceed 60 ° .
•
Ensure that
the angle between the two legs of the sling does not exceed 60 °
Multi-legged Slings:
• The recommended maximum angle between the two legs
of a sling is 90°.
• The recommended maximum angle between the vertical
and any leg of a sling is 45°.
• When slinging a rigid object with a multi-legged
sling it must be assumed that only two of the sling legs are taking the load.
