Krause’s illustration of three different preventative strategies and theireffect on the accident level (Krause 1995)
Economic Effect of Safety & Health to a Company
IOSH SEMINAR 2012
Accident Prevention
• Accident prevention is not about achieving ZERO risk, but rather about achieving ZERO accidents.
• This is achieved by ensuring that safety barriers are designed appropriately, that they are installed and functional, that they are cleaned and maintained, that instruction in their use is provided and finally that people are motivated to act in a safe manner.
IOSH SEMINAR 2012
Safety Barriers
IOSH SEMINAR 2012
Safety Barriers
Physical Safety Barrier– They are constructed and
designed appropriately– Installed according to
purpose,– Used as prescribed,– Checked continually and– Maintained in good
condition
Behavioral Safety Barrier– Procedures, plans, rules and
goals– Availability of good personnel
and planning– Competences and adaptation
of personnel and tasks– Commitment, involvement and
endeavouring to resolve conflicting situations
– Coordination and communication
IOSH SEMINAR 2012
Safety Barriers• Passive safety barriers are those that are incorporated
into the technology, process, procedures, etc. and which prevent undesirable events from occurring. These include technical safety precautions, automatic process procedures, targeted safety routine, etc.
• Active safety barriers are those that need to be learned by the individual so that he or she through his or her behaviour prevents undesirable events from occurring. These include safety instructions, safety procedures, safety standard and routines.
IOSH SEMINAR 2012
What We Need to Do?
• How do we ensure that such simultaneities of factors that can result in accidents do not arise?
• How do we create awareness that “simultaneities” can occur so that people have an opportunity to take the appropriate action?
• How do we ensure that people what they should do when they are in situations where a simultaneity of factors arises that can lead to an accident?
IOSH SEMINAR 2012
Safety Barriers And Risk Observations
• The employer shall ensure that the correct equipment is in place and in order, that employees know, how they shall use it, and are motivated for using it correctly, and that the employee knows what he must do, when and if the equipment fails or does not suit the task.
• The employer shall organise the work so that there is clarity over what he expects of the employee behaviourally, that the employee knows this and is motivated to fulfil these expectations.
• The employees shall pay regard to the competencies the individual has when organising the work, and he shall take part in improving these competencies, when this is needed out of regard to the job‟s performance.

BEFORE• 2D drawing, text, photo and video• Only Safety Manager has OSH knowledge• OSH are difficult to be predicted into design
and operation• OSH data & engineering data are segmented• Push based training
Virtual• 3D intelligent model• 3D Model maintained “ Life-Like experience”• Collaboration is active during design &
construction• Validate OSH procedure virtually and
interactively• Interactive training and learning• 3D intelligent model captures operation

3D Simulation for Behavioral Safety Barrier
Working Environment Investigation• The surface that is being travelled on or being worked on,
i.e. be careful, risk of falling• The surroundings that are being travelled or worked in,
i.e. see if there is a risk in your surroundings of something colliding with you from outside, or of you colliding with something, etc.
• What is being worked on or with, i.e. look at what you are working on and the risk of you becoming caught up/jammed in something, stabbing yourself, cutting yourself, straining yourself, etc.
• Surroundings of a particularly dangerous nature. i.e. conditions that require particular vigilance.

manual or semi-automated workplaces• Maximize operator comfort and safety
Solution Features & Benefits
Simulate workers to predict human performanceSimulate and choreograph multiple workers working in tandem
Evaluate manning level alternatives
Optimize Tasks performance
Detailed ergonomic analysis including RULA
Library of worker functions and actions for Construction industry
Optimize work center design
Analyze human interaction with devices, robots and processes
Analyze human interaction using vision

Work Crew Simulation, Planning, Resource Optimization, Safety & Training
Human Simulation
IOSH SEMINAR 2012
Optimize the Construction sequence by simulating key human tasks
Improve work center design and maximize worker safety and comfort
Use simulations as a learning environment for crew training and safety
Construction activities are simulated to check if there is physical conflicts.
Remedy work like redesign or reschedule can then be done to prevent
conflicts.

Design for Safety Operations and Maintenance
Value of 3D Simulation
• What shall be observed, which concerns observation of safety barriers
• How shall the observed safety barriers be quality assessed
• What types of action shall be taken based upon observations and the evaluation

Safety Training
• Expectation, understanding and motivation are based on what the individual perceives as being important. It is therefore appropriate to influence the individual's expectations and acknowledgement of risks and safety barriers through instruction, training and communication of goals and consequences.

Human behaviour as being the factor that triggers the accident
Industry Difficulties
Difficulties & Pressures• Method statement and working schedule normally in
writing and difficult to validate• Users demand better quality presentation• Complicated equipment installation and commissioning
manual• Safety issues demands for training repeatedly
