Module 3. Safe System of Work
Safe System of Work
Planning the work
Consider a few factors when planning work at
height:
• Weather conditions
• Check the safety of workplace
• Prevent Dropped objects , if it is not
possible to take appropriate actions
• Make a plan for emergencies and rescue.
Permit to Work
• The Person in Charge must obtain a permit to work covering
work at height, for any operations involving fall potential.
• This could include task specific permits with WAH controls
included.
• Upon any unscheduled work stoppage, unforeseen hazard or
emergency condition the issuer must withdraw the permit to
work and a new permit be raised to take into consideration the
change.
• The Permit to Work must be returned to the point of issue when
the work is complete or when work has been cancelled.
Safe System of Work
Risk Assessment
• Risk Assessment should be carried out when planning work at
any height.
• The law does not require you to eliminate all risks, but the risks
are minimized as much possible in practice.
Safe System of Work
Risk Asessment
• Careful examination of the working at height task,
• To whom and how it can damage.
Safe System of Work
Risk Assessment
Risk assessment consists of 5 stages:
• Hazard identification
• To whom and how it can damage
• Risk Assessment
• The results of recording
• Assessment review
Safe System of Work
Consider when you do Risk Assessment
• Falls from height
• Dropped objects
• Weather conditions
• Sea State in relation to vessel movement and over side /moon pool
rescue
• The level of competence of employees
• The health of Employees
• The stability of structures
• Employees fatigue
• Simultaneous operations
• Improper lighting
• Unauthorized access to the work area
• Poisonous gases
Safe System of Work
Risk control mechanism
First, is it possible
to avoid work at
height?
Prevent falls
from height
Mitigate the
outcome of falling
Do works at ground level
as possible.
For example:
 Use extendable tools
 Install cables at
ground level
You can do this by:
• Choosing a safe place
of work, such as it has
protection along the
perimeter of the roof
and no fragile surface.
• Use equipment to
prevent Dropped
• Scaffolding
• MEWP
If you can not reduce the risk
of falling, mitigate outcome
of falling
 Safety nets
 airbags
 anchor point

Topic 8. Openings and Edge Protection
Work may occasionally involve working near open edges of buildings.
Some examples are listed below:
• Working near the leading edge of a cold store roof during its
construction,
• Working near the edge of a completed cold store where a person may
fall down the cavity
• Working near the edge of a roof on a building, during the changing of
an air conditioner,
• Working on floors above ground floor of a building under construction
where edge protection has not been provided.
Openings and Edge Protection
• If work on a roof or floor involves nobody going closer than 2m to an
open edge, then full edge protection may not be necessary. In such
circumstances a demarcated work area should be clearly and access
restricted. Demarcation should be established by erecting an obvious
physical barrier and subject to strict supervision to ensure no one
strays outside
• If you encounter any situation where your work places you near an
open edge, then a thorough risk assessment must be carried out and
controls implemented, before work can commence.
Openings and Edge Protection
Topic 9. Roof Areas and Fragile Surfaces
• Accessing flat roof areas must initially be regarded as a high risk
activity which may require the services of a specialist contractor.
• Specialist equipment is often required e.g. MEWP’s, crawler boards,
safety netting and specifically fabricated walkways or edge protection.
Flat roof areas and fragile surfaces deemed hazardous to access must
be displayed by prominent warning signs.
Roof Areas and Fragile Surfaces
Roof Areas and Fragile Surfaces
When assessing tasks in such areas consider the following points…
• Can the work be completed from the ground or other safe area?
• Is the flat roof accessible and strong enough to work from?
• If working from the roof is required, does it have guardrails or other
equipment that will prevent a fall?
• If not, can guardrails or other equipment be installed?
• Can the work be achieved from a mobile elevated work platform
(MEWP) or tower scaffold?
• Is personal fall protection required to allow safe access?
• If a ladder is required, is the work low risk and short duration?
Topic 10. Requirements for Ladders

  • 108. Working Platforms MEWP • Operators and workers who work in basket should have proper health to handle MEWPs. • It is important to have a vision and knowledge for seeing awareness signs and properly understand the manufacturer's instructions for managing. • Hearing ability is one of the most important factors because the warning system is not always visible, sometimes audible signal is provided. • İt is the responsibility of the employer whether the employee is suitable or not for this kind of work
  • 109. Working Platforms MEWP It is not allowed to work with MEWP, if there are any health problems: • Heart disease • High blood Pressure • Epilepsy • Fear of heights • Dizziness • Weak function of Limbs (arm-leg) • Addicted to drugs or drink alcohol • Psychological problems
  • 110. Working Platforms MEWP • M.E.W.Ps divide into three main categories: • Group A – The center of working platform is on the same line with center of body. • Group B – The other groups • PAV (Push Around Vertical)
  • 112. Consider followings when choose appropriate MEWP for the task: • The type of work • Required height and radius • The number of workers and the total weight of equipment etc.. • The total weight on ground and the condition of the soil • Access to the workplace • Energy source (Electrical or Internal combustion engine, or liquefied petroleum gas) Working Platforms
  • 116. Topic 8. Openings and Edge Protection
  • 117. Work may occasionally involve working near open edges of buildings. Some examples are listed below: • Working near the leading edge of a cold store roof during its construction, • Working near the edge of a completed cold store where a person may fall down the cavity • Working near the edge of a roof on a building, during the changing of an air conditioner, • Working on floors above ground floor of a building under construction where edge protection has not been provided. Openings and Edge Protection
  • 118. • If work on a roof or floor involves nobody going closer than 2m to an open edge, then full edge protection may not be necessary. In such circumstances a demarcated work area should be clearly and access restricted. Demarcation should be established by erecting an obvious physical barrier and subject to strict supervision to ensure no one strays outside • If you encounter any situation where your work places you near an open edge, then a thorough risk assessment must be carried out and controls implemented, before work can commence. Openings and Edge Protection
  • 119. Topic 9. Roof Areas and Fragile Surfaces
  • 120. • Accessing flat roof areas must initially be regarded as a high risk activity which may require the services of a specialist contractor. • Specialist equipment is often required e.g. MEWP’s, crawler boards, safety netting and specifically fabricated walkways or edge protection. Flat roof areas and fragile surfaces deemed hazardous to access must be displayed by prominent warning signs. Roof Areas and Fragile Surfaces
  • 121. Roof Areas and Fragile Surfaces When assessing tasks in such areas consider the following points… • Can the work be completed from the ground or other safe area? • Is the flat roof accessible and strong enough to work from? • If working from the roof is required, does it have guardrails or other equipment that will prevent a fall? • If not, can guardrails or other equipment be installed? • Can the work be achieved from a mobile elevated work platform (MEWP) or tower scaffold? • Is personal fall protection required to allow safe access? • If a ladder is required, is the work low risk and short duration?
