There was a Bridge conference on Innovative Technologies on 25.05.18 and 26.05.18 at Lucknow. This presentation was made by Rajesh Prasad, ED RVNL during the panel discussion. This PPT contains a lot cartoons and images and conveys a big message on ensuring safety at construction worksites.

2. First Principle in Safety……..
• Do not PLAY with Safety….
- A matter of concern….

3. Good Physique
Regular Check ups
Preventive Measures &
Medicines
Proper & Timely Cure &
Restoration
A KEY TO LONG HEALTH LIFE OF MAN/STRUCTURE
Good Construction
Regular Inspections
Preventive Measures &
Materials
Proper & Timely Repairs &
Restoration

6. Construction Safety
Protocol: Near miss
is equally important

7. Herbert Heinrich showed that for every accident resulting in a
fatality or major disabling injury, there are approximately 300 unsafe
incidents. The take-home message is that by reducing the number of
near-misses you also reduce the chance of the fatality occurring,
because you have lowered frequency of at-risk behaviours.

9. PPE is the first of it’s requirements in
safety protocol

10. Safety Protocol : Little care make you safer

11. Safety Protocol : Be attentive and never relax…

12. Safety Protocol: Ensuring safety improves
body language and work culture..

13. Do not use
shortcut…
Basic principles of Safety Protocol:

14. Read and follow safety booklets for
safe construction protocol

15. Careless vis-a-vis Careful
Careful
Careless
Safety Protocol:

16. Cleanliness at
work sites
ensures better
Safety protocol..

17. Safe Construction protocol
brings a lot of happiness…

18. Construction Safety Protocol should be
part of team culture…
TEAMWORK divides the tasks and
multiplies the SUCCESS

19. It is linked to your safety and creates
safety culture at work site

20. Do not play with safety
and do not
compromise…
Safety Protocol:

21. Do not play with safety and do not make jokes
of it…
Safety Protocol:

22. Never play and never try to have fun…
Safety Protocol:

23. Never relax and play…
Construction Safety Protocol:

24. Do not play with safety and do not think
elsewhere

25. Ladder to success in project implementation is
to follow Safety regulations

26. Wearing safety harness correctly brings
confidence…

27. Non-wearing of safety harness may finish
you…

28. Display the safety posters and standards at worksite
Construction Safety Protocol:

29. All have to be careful…
Construction Safety Protocol:

30. For electrical matter and for earthing, take
extra precautions…

31. Safety first vs Safety last – choice is yours …
Construction Safety Protocol:

32. Look for danger and help others…
Construction Safety Protocol:

33. At site concentrate on works not on paper
Construction Safety Protocol:

34. Choice is yours?

35. Worksite is not the place to play, to enjoy or
to have fun…

36. Ultimate aim of Construction Safety Protocol
is to Construct Safe…

37. Helmet must, Safety first at workplaces…

38. Safety First Helmet Must

39. Never take chances…
Construction Safety Protocol:

40. Avoid phone and social media at worksite…
Construction Safety Protocol:

41. Love your family not the neighbors and
concentrate at workplace..
Construction Safety Protocol:

42. A FEW FACTS:
 The first few weeks on each new site is the most
dangerous.
 Accidents are more frequent at the end of the
day.
 Construction over busy roads.
 Safety helmets, Hi-viz jackets, safety boots do
prevent injury and death.
 Light weight shoes-such as trainers or runners
are not suitable at site.
 Idling/Stoppage of worksite make the worksite
vulnerable…

43. Construction Accidents
• 56% falls from height
• 21% trapped by something collapsing or
overturning
• 10% struck by a moving vehicle
• 5% contact with electricity or electrical discharge
• 4% struck by a flying/falling object during machine
lifting of materials
• 3% contact with moving machinery or material
being machined
• 1% exposure to a hot or harmful substance
Breakdown of fatalities according to type
of accident in construction industry

44. Safe Access on Site
 Everyone can get to their place of work
safely
 Edges from which people could fall are
provided with double guard rails or other
suitable edge protection
 Holes are protected with clearly marked and
fixed covers to prevent falls
 Site is tidy
 Good Lighting
 Fenced off from public

45. Working at Height
Height HAZARDS on Construction Sites
Holes in Floors, Gaps on Working Platforms, Shafts and
Stairwells not Adequately Covered, Barricaded, Fenced Off
 Using ladders or scaffolding without
proper fixing is crazy
 Never use incomplete scaffolding.
 Make sure there are hand rails and toe
boards at all edges
 Things fall on sites, wear your helmet
 Before starting work at heights check for
clearance from any overhead power lines

46. LETHAL LADDERS
 Right for the job. Would scaffolding
or a cherry picker be better?
 In good shape
 Secured near the top
 On a firm base and footing
 Rising at least 1 meter beyond the landing
place
or that there is a proper hand hold
Always have a firm grip on the ladder and
keep a good balance
Ladders kill a lot of people.
Make sure the ladder is:-

47. CRANE SAFETY
• The weight of the load must be carefully
estimated
• The crane must be fitted with an automatic safe
load indicator (one that works)
• The crane must always work on a hard, level base
• The load must be properly fixed and secured
• The banksman must be trained to give clear
signals
• Third party inspection and trials
• Testing and third party inspection of wire rope.
• Checklist
Very Simply :-

48. Traffic Vehicles & Plant
 Vehicles and pedestrians should be
kept apart on- site – separate them
as much as possible using barriers
 Adequate clearance around slewing
vehicles
 Avoid reversing where possible &
use one-way system
 Vehicles should have reversing
alarms/sirens

49. ELECTRICITY
• Treat electricity with respect
• Check constantly that cables are not
damaged or worn
• Keep trailing cables off the ground
and away from water
• Never overload or use makeshift
plugs and fuses
Good practice with electricity at site:-

50. PPE on-site
Most construction sites require at least:
• Hard hat
• Safety Boots
• Hi-viz jacket
• Safety Glasses
Wear them always for your safety

51. Construction Site Safety
No job is so important that it cannot be done
safely
UNDER NO CIRCUMSTANCES ARE PERSONS
WORKING ON SITE TO PUT THEMSELVES IN
DANGER
BEST - BE Safe Today

52. Checks…
• Ensuring work permits
• Internal/ External safe audits in regular
frequencies
• Checklists throughout the construction phase
• Display safety posters and assurance
• Preparation of audit reports for check
• Indentifying non conformant, non compliance
• Near misses actions which has ability to
cause risk
• Legal requirements

53. May not get the chance of hospital trip

54. SAFETY MEASURES TAKEN AT WORK SITE
Proper barricading at site to protect Motorists, Pedestrians,
Workmen, Plant & Equipment from accident

55. • Display of temporary traffic signs as per the requirement of the
Traffic Police.

60. Monitoring System at tunnel site
• Controlled blasting
• Monitoring system for
measuring vibration in the
existing tunnel during
blasting of 3rd line.
• Seismograph equipment was
installed in near by existing
tunnel wall during every
blasting to record the
blasting amplitude and
frequency of shock wave.

61. The summary of blast vibration
and Fast Fourier Transform
Analysis (FFT)
PPV = 4.572 mm/s< 10mm/sec.
Noise = 106.0 dB < 146 dB

62. • 6 nos. sensors have been installed on the stay
cables subjected to maximum loads. The ROBO
Control System of M/s Mageba .
• The structural monitoring system issues alarm
notification based on measurements by the on-
structure instrumentation when pre-defined
threshold values of structural loads are passed.

66. WE, CARE FOR THE SAFETY OF YOUNG AND
OLD
ALL SHOULD FOLLOW THE SAFETY RULES AS
DISCUSSED AND TOLD
AFTER THOUGHT….

67. Safety -- a small investment
for a rich future.
Safety can distinguish you.
Lack of safety can extinguish
you.

69. Safety comes in cans :
I can, you can, we can.
