Fall protection training is crucial for any worker who performs work at height. Without the proper training, workers may not realize the severe consequences of a fall - serious injury or even death. Training consists of both classroom learning on topics such as industry standards, as well as hands-on training about how to use fall protection equipment, among other topics.
It is the company’s obligation to make sure all workers are educated in how to properly use equipment, including devices that are sometimes overlooked, such as a self-retracting lifeline (SRL).
SRLs are becoming more common on job sites because they reduce fall distance and fall clearance requirements. The devices have also become smaller, lighter and more economical, making them an increasingly popular choice over shock- absorbing lanyards. Based on the growing popularity of SRLs, it is critical that fall protection training courses teach workers how to use these devices correctly.
A self-retracting lifeline is a fall arrest device incorporating a lifeline that extends and retracts as a worker moves away from and toward the device. In the event of a fall, an energy-absorbing brake activates, stopping the fall while reducing fall arrest forces and fall distances to safe levels.
The lifeline is made of either galvanized or stainless steel cable or nylon webbing. SRLs are typically used when a great deal of mobility is needed on a job site. The amount of mobility is limited only by the length of the SRL’s lifeline, which can range from six feet to 175 feet or greater. Self-retracting lifelines are used extensively in the oil and gas industry, but the devices are also common in construction, general industry, transportation, utilities and wind energy.
Several types of SRLs are common on job sites; selecting the right type depends upon the work environment and the type of work to be performed.
For example, sealed SRLs completely seal all dynamic components such as the motor spring and brake system inside the housing to protect the mechanisms from oil, grease, dirt and saltwater, making them ideal for use in dirty or corrosive environments.
Certain activities such as welding require the SRL’s lifeline to be made of steel material or Kevlar, versus nylon, to protect it from heat and flames. Leading edge SRLs are available with lifelines that are resistant to damage from sharp, abrasive leading edges found on many construction sites.
Compared to shock-absorbing lanyards, SRLs reduce the fall distance required for deceleration and fall arrest, making them preferred equipment for sites with low clearances or where work hazards cannot be bypassed or isolated.
Many fall protection training courses touch only briefly on SRLs without fully explaining what users need to know. Training for authorized persons should include training on how to safely use a self-retracting lifeline.
