Falls are one of the leading causes of death. Between 2003 and 2013, around 3500 fatalities were recorded due to the lack of safety measures, which makes up 34% of the deaths that occurred in that time period.
There are many hazards that roofers are faced with, such as power tools, extreme temperatures, ladders, electricity, and noise. In order to counter these hazards, they have to be controlled by the employer so that the roofers do not risk serious injury, death, or illness.
Falls are one of the top causes of work-related deaths and injuries among roofers. An improper setup, damaged fall protection, or a complete lack of fall protection increase the risk of falling from a height. Here is a way that employers can tackle this problem. If you are in the market for roof repair, make sure you abide by these rules or find a reputable roofing company that can handle the work load.
Installing a Personal Fall arrest system
Personal fall arrest systems are designed to safely stop an occurring fall before the worker strikes a lower level. These systems have three major components:
A. A connector that links the harness to the anchorage.
B. A harness for the whole body worn by the roofer.
C. The lanyards hook attached to an anchorage.
Personal fall arrest systems use a deceleration device to reduce the velocity of the falling roofer, a lifeline that is self-retractable, and a thong that is used for tightening the clothes or fastening armor.
The lower level is necessary to ensure so that the roofer avoids contact with the ground if a fall occurs. The total fall distance is measured as the minimum vertical distance between the roofer and the lower level.
To ensure that the proper fall protection is selected, it is necessary for employers to calculate the lower level distance as precisely as they can. The factors that have to be taken into consideration when calculating the fall distance are given below:
1- Safety Margin: In order to ensure safety, it is ideal if the employer maintains a safety margin of at least 2 feet between the lower level and the worker.
2- Deceleration distance: Deceleration distance is the space stretched by the lanyard to arrest the fall. The ideal distance is around 3.5 feet, although it may vary for different fall arrest systems.
3- Back D-ring height: The D-ring height is the distance between the sole of the workers’ footwear and the D-ring. A standard distance that is used by the employers is 5 feet for a worker who is 6 feet tall. The height of the D-ring has to be adjusted accordingly for employees with a short or long height.
4- Shift of the D-ring: This shift is the calculation of how far the harness stretches and the shift of the D-ring while supporting the complete body weight of the worker. The weight of any attached tool or equipment and the weight of the tool belt are also included. Mostly, employers estimate that this shift is about 1 foot, although it varies depending on the design of the equipment and the manufacturer.
