:Risk Control Methods
The incident reports confirm that a large proportion of accidents
due to the actions of others safe from staff - that the definition of danger or
risk factor expected and how to deal with it leads to the proper performance of
the worker in order to prevent such hazards.
:
The Organization of occupational health and safety the first to apply this
method.
This method is easy and directly in the application and provide for effective
sanctions for those who did not apply the safety rules and adhere to them.
To be sure of sanctions against violators of safety rules effective and
influential, and so must be the gradient in the severity of these sanctions
until we are deciding whether to have signed.
B - the use of warning signs:
Must use the specific phrases such as influential and is strictly prohibited,
or always
This method may lead to follow safety rules, especially at the beginning of
their application, but do not lead to improved effective in reducing injuries
and occupational diseases.
Example of a real case:
:
Result of the application to impose safety rules, which leads to increased
stress on the workers must be followed by this method and the method of
psychological treatment of this method depends on the following:
- The teachings of religion to take into account things improve safety
and take calls caution when risks.
- Support from senior management is to reward excellence in safety
matters
Strengthen the safety measures - role models to follow the safety instructions
........ etc..
- Interest in new workers, especially in the application of methods and safety
Baltrgab assign the task of training people to be role models to them and
Hannah are skilled so that they can inform them properly.
:
That the technological development of equipment and machinery led to the
importance of processing engineering places the business in order to avoid a
hazard
:
There are three lines of protection to avoid the occurrence of risks
1 - Monitoring and Control Engineering.
The management control in the
execution of the works safely and effectively.
2 - personal protective equipment.
Providing and requiring workers to use
personal protective equipment at work
3 - Monitoring and Control Engineering.
The use of engineering approaches to address the risks and avoid having a
positive impact in these things, and we review here some important factors that
influence this way:
:
Safety factor
Whenever the coefficient of safety large whenever the stomach is more secure
and safe, but there are limitations determine the value of the coefficient of
cost and size of the material used in the implementation of design and
therefore has to be a balance between the value of plants and the cost and size
of the material used to achieve the required security with cost The appropriate safety factor in
engineering design has a significant impact in making the component designer is
working safely and with a great deal to maintain the integrity of the Group.
Safety factor means the addition of certain key accounts.
Cranes will be when you have a safety factor 1:5 design, but the safety factor
in a pregnancy (chains or ropes) is 1:6 in order to be more secure.
:
In addition to the safety factor in there are the basics of engineering design
must take into account a reaction system as a whole when the collapse of the most
effective components, and is called to stop the basics of safe and known as
follows:
:
The general rule to stop the safe
The general rule in the case of the collapse of one of the components of the
system occurs a safe stop.
Systems usually have two phases, one phase is called the effective and the
other is called the passive phase and usually in the passive phase, the
Almknyat Oktherhma safer and therefore most of the machines are instructions to
the workers in time of danger pull the plug will not get hurt.
But not in all cases, phase inert be safer there are systems designed so that
when a particular risk there is a part of the system works to protect the
worker and the workplace of any risks arising from the collapse of one of the
components of the system and in this case, the attraction plug lead to the
disruption of this part of the
system and thus lead to the occurrence of risk to the worker and the
surrounding workplace.
So make sure Valabd of engineering during the design phase that in the event of
any breakdown in the system, the system is in a state is completely safe.
:(
Drill Alheidoreliky of the Earth When the collapse of any of the worker, it
leaves the drill and thus stop the drill and the phase here is the passive
phase of the Safe
:(
Car steering wheel with automatic and automatic Kabbahat If you see a
particular risk if the machine was stopped to avoid this danger can be
difficult where the wheel brakes do not work except in the case of rotation of
the engine.
Therefore, the passive phase in this case is not safe.
:
In this case, the critical and important function of the system or parts of the
system or components serving more than one choice to be in parallel or units are
on call.
This system is used widely in the aerospace industry and aircraft and the
important and complex systems.
Worst-case base:
Murphy Law states that if there is a possibility that the occurrence of public
danger expected from this system even if the probability of occurrence is very
small, this risk must be located.
Based on this law, the system must be designed to avoid any risk even if the
incidence is small and may find this principle susceptible of many people,
especially business owners and industrialists, but from the point of view of
safety officials, this principle has been rehabilitated.
:
There in the case of storage and use of flammable materials usually rising
vapors of these materials leads to the ignition and cause fire accidents and
therefore, the use of motors, especially in the ventilation systems for these
places to prevent occurrence of such risks and with the proportion of fumes to
be under control, but may occur.
The use of motors in the normal operations of ventilation may not prevent the
occurrence of such hazards.
And therefore according to the law of Murphy, the use of motors on despite
their high cost and more useful and safe, but this logic meets resistance from
industrialists and the owners of the funds.
Fundamentals should be considered in the design phase of
the
stomach from the viewpoint of safety
- Avoid the causes and processes that cause risks.
- Develop alternatives to safe operations or materials.
- Protect the worker from exposure to hazards.
- Establishment of a protective fence to make the worker away from the source
of danger.
- Develop audio alarm or visual warning when a worker through the stomach.
- Using posters guidance on the machine to warn the worker from the source of
danger.
- Use filters to prevent worker exposure to any toxic products of the
operational process.
- Design ventilation system to get rid of the exhaust in a healthy and safe.
- Taking into account the overlap between the worker and the machine.
The dangers of engineering solutions:
There are dangers that may occur from engineering solutions to the problems and
this means that with technological advances, there are still dangers that may
result from the application of engineering solutions to problems, for example:
The use of valve Alzenbaraky pieces in the line of compressed air when
you use the tools so that the valve leading to the suspension of compressed air
tool if separated from the compressed air hose at work.
This valve may not function properly if used more than one tool all
graduated from Khartoum
Workers always used to remove the protective equipment of Almknyat the
grounds that they impede or slow down and work through this output of the
engineering design of such equipment.
:
The use of analytical methods in the analysis of incidents and access to the
causes of accidents is one of the active ingredients that affect access to the
causes of accidents and avoid the occurrence of accidents in the future and
improve the level of safety.
:
* Method of analyzing the style of collapse and its effects
Is a method for the analysis of complex engineering systems step by step
through a series of questions.
* Hybrid method of analysis of the defects
Is a method used in the prediction notification and try to prevent frequent or
used in the analysis of the event after the fact.
* Type curve analysis of the tree of events
Is the logical way to find all the possible outcomes of the primary event.
* Hybrid method of analysis of the errors
- Select the event under study (top event tree).
- Identify a number of causes for the event using the
logic gates (or - f) - Events in the average level.
- Determine the underlying causes of the events of the
medium.
- The curve event tree analysis
- Identify the basic event which could lead to the
collapse of the system.
- Determine the causes which affect the main event and
attempt to remove or reduce the defects caused in the main event.
* Method of analyzing the style of collapse and its effects
- Identify the elements which will be studied because
of their importance to the system.
- Determine the effects of collapse.
- Determine the required corrective actions.
Safety and occupational health impact on competition?
When the herb increases the safety level of injuries and therefore this will
lead to the following:
- Compensate for the difficulty in the workplace workers infected with the same
skill.
- Lack of Alantegbh and this will lead to a lack of competition.
- The high level waste.
- High probability of occurrence of the destruction of a high-tech systems.
- A large number of employment inappropriate in the workplace.
These factors lead to reduce the chances of winning the competition
