Overview
The ERDI Dry Suit Operations programme develops the knowledge and practical skills necessary to plan and execute dry suit diving operations within public safety and emergency response environments.
Dry suits are widely utilised within public safety diving due to:
- thermal protection,
- environmental isolation,
- contamination reduction,
- and increased operational safety in cold or hazardous environments.
Training focuses on:
- dry suit configuration,
- buoyancy management,
- operational movement,
- emergency procedures,
- environmental hazards,
- contamination awareness,
- and public safety operational procedures.
At N9BO℠, this programme is delivered as operational public safety diver training, emphasising procedural discipline, operational readiness, equipment familiarity, and real-world emergency response capability.
This programme is available through all three ERDI role tiers: Awareness, Operations, Technician (learn more about ERDI role classifications and operational pathways on our main ERDI Public Safety Diving page).
