KStrong®, Unrivaled Safety KStrong has been successfully manufacturing fall protection components and systems globally for over 20 years and is now poised to become the preeminent brand of choice in the USA! Full Body Harnesses - Lanyards - Self-Retracting Lifelines - Connectors - Anchors - Confined Space Rescue Retrieval Equipment - Engineered Vertical and Horizontal Lifeline Systems Fall protection products are lifesaving devices, and the mere procurement for your workforce does not guarantee complete safety. After making an investment in your fall protection equipment, it is critical that the end user is properly trained on its inspection and use, and is aware of the periodic maintenance process that requires that all personal protective equipment (PPE) be inspected in accordance to the requirements of employers, governmental codes and ANSI standards. Your Fall Protection Equipment Can Now Speak To You! Introducing KStrong Compass™, the fall protection industry’s first “free at your fingertips” mobile application for fall protection equipment asset management. KStrong Compass™ is a cloud-based software app which relieves the user from a mountain of paper records. The unique AIR system (Automated Inspection Reminder system) reminds a user of a pending competent person inspection that is required to minimize accidents that may happen due to equipment that has not been properly inspected. The KStrong Compass™ user management system allows equipment to be issued to individuals, thus ensuring accountability towards the upkeep of the equipment. The mobile app provides each user vital information on inspection and periodic maintenance needs and helps in increasing the life of the equipment. Using KStrong Compass™ is a wise decision to cut down costs on PPE. Identifying a product through labels throughout its service life is difficult. The labels get damaged often making them difficult to read or become missing altogether over time. KStrong Compass™ has the unique ability to read QR codes, RFID tags, and can even directly scan product labels. Thus, identifying a product and its user is a click away. What Does An End-User Need to Start Using KStrong Compass™? If you have an IOS device, that is all you need.
