The Malta Dynamics guide to self-retracting lifelines

In the ever-evolving landscape of fall protection and safety, it is essential for manufacturers and users alike to adhere to the latest standards to ensure optimal worker protection. One of the critical benchmarks in this domain is the ANSI standard for Self-Retracting Lifelines (SRLs). In this blog, we’ll dive into the transition from the old standard, ANSI Z359.14-2014, to the new standard, ANSI Z359.14-2021, exploring the changes, implications, and how Malta Dynamics, as leaders in fall protection, have exceeded the requirements.

The new standard: ANSI Z359.14-2021

With the release of ANSI Z359.14-2021, significant changes have been introduced to enhance worker safety. The new standard has replaced Class A and Class B with Class 1, designed exclusively for overhead use. The key parameters are as follows:

  • Max Arresting Force: 1800 lbs. or less
  • Average Arresting Force: 1350 lbs. or less
  • Average Arresting Distance: 42″ or less

This revision allows manufacturers to list SRLs at or below these maximums. Additionally, the mass dynamic impact testing has increased from 282 lbs. to 310 lbs. (10%), and the static strength test has increased from 3000 lbs. to 3600 lbs. (20%).

In the realm of safety compliance, the ANSI Standard sets a crucial benchmark for Class 2 devices, mandating that they undergo Class 1 classifications before completing the Class 2 testing procedures. The Malta Dynamics 20”, 30”, and 50” EdgeHog Class 2 devices exceeded expectations when utilized in a Class 1 setting with above D-ring tie-off. The performance of these devices stood out, aligning with industry-leading standards.

When deployed overhead, the Malta Dynamics EdgeHog Class 2 devices demonstrate arresting forces averaging less than 900lbs, coupled with arresting distances comfortably meeting the 42″ requirement. This bears significance as it impacts numerous existing engineered fall protection systems, including rigid track systems and horizontal lifelines, originally designed under the previous ANSI Z359.14-2014 Class B classifications (featuring 900lbs max average arresting forces and 54″ max arresting distances). The EdgeHog seamlessly transitions into these systems, offering an even shorter stopping distance, 900lbs represents only 33% of the 1350lbs maximum.

The Malta Dynamics EdgeHog Class 2 devices not only adhere to stringent ANSI standards but also elevate safety expectations by providing optimal performance within existing frameworks. This marks a pivotal stride towards enhanced workplace safety and underscores the adaptability and excellence of these devices in the ever-evolving landscape of fall protection.

Specific CLASS 1 & 2 device changes in ANSI Z359.14-2021:

Class 1 Devices:

  • Use at or above dorsal D-Ring
  • Class 1 Icon Required

Class 2 Devices (Previously referred to as Leading Edge Device):

  • Designed to be used above or below dorsal D-Ring
  • Class 2 Icon Required
  • Warning Card Required with all Class 2 Devices
  • Fall Clearance Chart and Axis Chart Required on shock packs (Large models)
  • Used anytime a cable may come in contact with an edge

Implementation for your team (fall protection plan, rescue plan, other documentation)

Your current Fall Protection or Rescue Plan may say ‘Class A, Class B, Leading Edge Lifeline’, or maybe call out a specific item or part number. Consider updating to the language in the new standard, in addition to the current, or making language broad enough to cover both standard sets, such as ‘A self-retracting lifeline with less than 900 lbs. average arresting force, and maximum arresting distance of 42″.

Malta Dynamics’ industry-leading SRLS

In response to these changes, Malta Dynamics took a proactive approach to design SRLs that not only meet but surpass the industry standard by significant margins.

Malta Dynamics’ SRLs arrest workers in a shorter distance, while simultaneously providing enhanced protection against industry standard forces. The goal is not just to catch workers but also to minimize the risk of injuries associated with forces exerted during a fall.

Beyond compliance: Additional safety factors

Recognizing that traditional safety factors in SRLs are comparatively smaller, Malta Dynamics went the extra mile. At Malta Dynamics, we have built additional safety factors into its devices, allowing engineers to review actual 3rd party test data during the installation of track systems, anchor systems, etc. This approach enables the consideration of temperature and environmental factors, ensuring that the safety parameters are accurately aligned with real-world conditions.

Rigorous testing standards

Malta Dynamics ensures the highest standards of safety through rigorous testing protocols. All devices undergo 3rd party testing in an ISO 17025 lab, are subjected to 3rd party batch testing post-production, and undergo 1st party batch testing before being released for sale.

Malta Dynamics is deeply committed to enhancing safety standards in the fall protection industry by actively participating in the ANSI Z359 Committee. As proud members, they attend bi-annual meetings where they contribute through voting and recommendations. This dedicated involvement allows Malta Dynamics to play a key role in shaping industry regulations, ensuring the highest safety standards. By actively engaging in these discussions, they not only stay informed about the latest developments but actively contribute to the ongoing progress of safety protocols. This commitment underscores their dedication to the well-being of workers, establishing Malta Dynamics as a trusted leader in the field of fall protection.

In conclusion, the transition from ANSI Z359.14-2014 to ANSI Z359.14-2021 signifies a commitment to enhancing worker safety in the fall protection industry. Malta Dynamics, as leaders in this space, not only meets the new standards but surpasses them, ensuring that workers are protected with the utmost care and precision. As the industry evolves, Malta Dynamics remains at the forefront, setting new benchmarks for excellence in fall protection and safety.
