Emergency Response Diver Level 1 Course

This initial ERDI diver course prepares you in-depth with the Public Safety Diving basics, both on theory, equipment and skill level, to be part of an NFPA and OHSA compliant Public Safety Diver team. Upon certification, the candidate will be able to operate both as a diver and tender in limited open water public safety diving activities.

This course is your foundation. You’ll learn to be self-sufficient under water through a series of skills, drills and techniques. Most of your dives as a PSD are solo dives. The only interaction with safety or a buddy is through a thick rope and an array of signals. The tender can pull you out of the water at any time, but in reality, you’re still diving solo. The training will prepare you to overcome most challenges or failures by yourself. For example; Entanglement, gas failure, loss of visibility. 

The candidate therefore receives a challenging but rewarding course using basic scuba. To enter the course, you need to be a certified open water diver from a recognized agency and proof of basic first aid/oxygen provider training. Your waterman ship will be tested as well as rescue skills. 

The theory portion takes you through the practical and legal facets of public safety diving these are followed by confined water training sessions to familiarize you with your equipment before you head to open water training. 

Working as a team, the candidates rotate through every role within the dive team such as primary search and recovery diver, tender, backup diver and incident commander.
