4. The Plan for Safety is
Step 1 Hazard Identification - STARRT, RA
Step 2 Stress on house keeping – Daily ½ Hour EOD
Step 3 Tool box talks & Training Induction ,RMGM
Step 4 Daily Observations area wise - Safety officers
Step 5 Access Egress Traffic management ,MEPI
Step 6 Work Permit System & Job rotation
Step 7 Internal & External Audits -CAPA
Step 8 Enforcement of PPE Glove selection MSDS
Step 9 Daily Weekly & Monthly review meetings

5. Major Safety Consideration with the column and
retaining wall work is work at height and
Scaffolding .
All work above 1.8 meters height shall be based on
height work permit procedures and as per
standard 214.
All ladders shall be inspected and issued through
stores ,a register/ log book shall be maintained .

6. All scaffolds shall be erected as per standard 215.
The scaffolding shall be used for building up the
rebars , form work and the concreting operations.
All and each individual activity shall not proceed
without STARRTalk being conducted by the
foreman.
Scaffolds shall be extended in height at strategic
locations and these shall be used as anchorage
for Personal fall protection where lifelines cannot
be erected or are not reasonably practicable

7. Mobile scaffold and ladders shall be available for
rescue work incase of a fall as the person using
fall protection is hung for more than 15 minutes .
The Male nurse is the head of the Initial emergency
response team.
Strict Adherence to precautions mentioned in the
height work permit, 100% hook up using twin
lanyard of the personal fall protection / FBH

8. Major safety consideration for slab casting is work
at height and scaffolding as discussed in previous
slides.
Precast erection is primarily a lifting operation
HHC transfers this risk to an approved Contractor
EPC the operations shall not commence without
an approved method statement and Risk
assessment.
The double tee erection which is the single largest
of the operation as well as all other lifts shall be
as per standard 221

9. The crane operator , lifting competent person shall
all meet the requirements as specified in the
standard 221.
The lift calculations shall be submitted well in
advance at least 3 weeks in advance to
Commencement of operations as per standard 221.
All the sub contractor personnel shall be provided
induction and tool box talk apart from STARRT
prior to operations.
All rigging equipment shall be issued from store after
Inspection &verification of validity of TPC

10.  Excavation safety - care to obtain permit to dig ,
excavation work permit , trail pits
 Protect employees from cave-ins
 Barricades , spoil distance maintained
 Competent person in place
 Excavation Log
 TMP showing excavations , MEPI
 Confined Space Training

11.  HHC chooses to transfer the risk associated with
Jack and slide operation to the sub contractor
who is a specialist in the field .
 The Road safety aspect of the movement of the
low boy trailer shall be as per the approved RC
procedure this will be preceded by a route
survey
 The use of beams dun nage hydraulic jacks and
power packs Present hazards of crushing &
falling objects this hall be taken care of by
restricting the access to the work area, proper

12.  Blocked roads provided with appropriate signage.
 Flag man at each end of the blocked roads.(shifts &
supervision )
 Concrete barricades for safety.
 Night lighting to prevent accidents.
 Dedicadeted banks men for controlling the movement of
construction plant such as dumper, excavator etc.,
 Flags man, blanks men training.(shifts & supervision )
 Red man & green man training.
 Emergency initial response team.
 Arabic & English signage showing the detour route.
 Provision of Arabic speaking supervisor.
 Provision of appropriate paddles flags ,PPE to flags man
& banks man etc.,

13.  Excavation competent person & supervisor to handle
the excavation process and the work to proceed under
the permit to work system.
 Reference to as laid drawings where available if not,
use of trail pits for detection of buried services.
 Site inspection and survey and identification of over
head or buried services prior to issue of work permit.
 Protection of workers by ensuring correct design of
sloping and shoring systems, use of trench boxes as
required.
 Prevention of cave in by ensuring that spoil is kept
away by a minimum distance equal to depth of the
excavation, barricades at a minimum of 6 feet from
the edge of the excavation and dewatering done
where required.

14.  Restricting the movement of vehicles around the
excavation to avoid surcharging, use of stop blocks
for preventing plant from falling into excavation.
 Appropriate handling of material and equipment.
 Red man and green man training to all involved in
the work.
 STARRT talk on excavation and hazards involved
prior to start of work.
 Risk assessment and method statement approval
prior to issue of permit to work.
 Arrangement of access and egress such that a worker
will walk a maximum of 25 feet to access exits.
 Ladders to extend 1m above the excavation edge.
 Regular inspection of excavation by supervisor and
excavation competent person.

15. CONFINED SPACE MANAGEMENT
FOR UG WORKS
 Any enclosed or partially enclosed space located either
above or below ground or deck level where entry is
possible and where is a risk of oxygen deficiency or
enrichment the accumulation of dust or gases which are
flammable or hazardous.
 Large enough to enter and work but has limited access or
egress.
 Not designed for human occupancy.

16.  Where required by method statement
and risk assessment RPE and local
exhaust ventilation shall be arranged.
 All entrants into the confined space shall
be trained and certified prior to work.
 All confined spaces shall have a
dedicated confined space attendant.
 Gas testing shall take place prior to start
of work and gases in the confined space
monitored at 15 minute intervals.
 A proper communication plan in place.
 Emergency response team and
ambulance availability.
 Fire watch incase of hot works.
