Otto Worksite Assistant is a companion app designed to interact with your Otto technology-enabled equipment. Otto Tech Systems invented this technology for construction equipment routinely used on construction sites. This technology takes training, supervision, and equipment design to the next level and can aid in faster and more precise diagnoses of injuries. It also helps promote safer worker behavior on worksites by giving seasoned professionals the knowledge, tools, and processes they need to work safely, meet higher standards, and improve every day. The Otto Worksite Assistant app links the professional to their equipment to provide an individual safety profile and links management to enable decisions or customize training that helps prevent accidents. The app helps the professional create and update their profiles and upload their certifications. It also allows the professional to confirm the integrity of the equipment prior to use. The Otto Worksite Pro technology provides real-time audible alerts to warn professionals of potential risky behavior and to text supervisors to take immediate action to keep their team members safe. Prediction enables prevention because if you have the data to predict an accident, you can take steps to prevent an accident.
