There are various types of emergency alert systems available in the construction industry from the air horn to more complex remote and app-based systems. This study utilizes an industry survey to identify the most commonly used emergency alert methods on jobsites, and the industry professionals’ knowledge and perceptions of app-based and remote emergency alert systems. Results indicate that the air horn is the most commonly used method of emergency alerts, and the construction industry is willing to spend more on the remote emergency alert systems compared to the app-based emergency alert systems. The major concerns from the construction industry are the overall cost and reliability of the high tech systems, and the potential for false alarms. Results show that if the concerns of the construction industry are addressed, companies are willing to spend more on the app-based systems.
