- Horizantal Lifeline
We are here to solve problems.What is Lifeline, Why is it Necessary?
Lifelines play an important role in occupational safety and worker health in work at height. It is applied in order to prevent accidents that may occur during work at height and result in death, and to prevent material and moral losses of both the employer and the employee. The place of work; If there is a risk of injury in the event of a fall, whether below or above ground level, the work done in these places is called “working at height”. ( 6 April 2005 / Working at Height Regulation / England)
The lower limit for working at height, which differs from country to country, is 1.80 m in Europe and 1.20 m in the USA.
In the world and in our country, falling from a height in occupational accidents that occur during working at height is in the second place after motor vehicle accidents among all fatal cases.
Horizontal Life Lines;
It is generally applied on roofs, warehouses, factories, etc. where working at height is required. Horizontal Lifelines must comply with EN 795:2012 standard. Horizontal lifelines are basically the system where the risk of falling starts, the steel rope installed along the edges close to the gap and the fall arrest equipment that does not need to be disassembled while passing the anchor points attached to it. The installation of the lifelines should be done by the expert assembly team. All system elements must be stainless steel and tested in accordance with EN 795 standard.
What is Height?
The concept of height is relative and varies from person to person. In general, height; It can be defined as places that we cannot go out by taking a step.
While defining the concept of height, which differs from person to person, the measure we will base on is the human body.
Although people are different from each other, the balance point of a person is the second lumbar vertebra. In other words, places that pass the second lumbar vertebra are considered high.
Human balance point on the spine 1.2 m, 1.8 human height,
Above and below us, where we will be hurt if we fall, everywhere we need to get out with support
What is a Fall?
Falls are the most fatal accidents in the construction industry. It is seen that 85% of the workers who fell while working on 3-4 meters lost their lives. Most of the employees believe that they will have enough time to hold on to the right and left during the fall. A person's reaction time to a fall is around 0.1 sec. Considering that there may be a 0.1 second delay for the reaction, you have dropped 20 cm.
Fall Factor
Definition
•Drop factor 2; is that the distance deducted is twice the distance between the station (connection) point and the worker.
•2 factor decrease in practice; occurs when the connection point is at foot level
Factor 2 drop example
2x interconnect size
1x absorber maximum opening length (1.75 m/1.9 yds.)
1x safety margin (1 m/1.1 yds.)
= 6.75 m/7.4 yds.
Some of the internal damages are:
• Lungs
•Liver
•Heart
•Spleen
• Kidneys
FALL DISTANCE
Fall factor and fall margin Fall factor (fall factor); It is the relationship between the height of the fall and the length of the rope or lanyard that absorbs the energy of the fall. The following formula is used to calculate it (distance dropped divided by the length of the rope or lanyard): Drop factor = Distance dropped / length of rope or sling Drop allowance The minimum distance necessary to avoid hitting the ground during a fall. Shock absorbers absorb the fall force acting on the wearer. There is a risk of serious injury from falls if shock absorbers are not used. In shock absorbers, the system lengthens and absorbs the energy of the fall. This amount of elongation should be taken into account and added to the drop margin.
HOW DO WE FALL?
Moving from one level to another
• Cavities, shafts and unprotected holes
• Inappropriate bearing capacity of work platforms
• Slippery surface
• Inappropriate shoes
• Soft ground
• bad weather conditions
• Vehicle crash
WHY ARE WE FALLING, INJURED?
•Lack of Knowledge: The person does not have the necessary and sufficient information about the work he/she does and the equipment he/she uses.
• Staff Assignment: Not assigning the right staff to the right job. Incompatibility of the work with the physical structure of the employee (low vision, hearing, inability to use any organ, etc.)
• Failure to Implement Occupational Safety Rules: Managers do not believe in the necessity of occupational safety rules and do not train their personnel for the implementation of these committees.
•Engineering:Designed system complicates safe operation; does not meet the minimum requirements of the job.
• Inadequate Personal Protective Equipment PPE: Not using or insufficient Personal Protective Equipment PPE. Not wearing a helmet, not using gloves or glasses, not following the cleaning rules, etc.
HOW CAN A FALL BE AVOIDED?
Avoiding working at height
• Correct use and maintenance of PPE
•Personnel training and control
Fall arrest systems
•Lifelines
•Design according to the possibility of falling
Horizontal lifelines cannot fully fulfill their functions unless a correct design is made. For the correct installation of the line, the complete determination of the requirements
