HEMS Paramedics undergoing Helicopter Underwater Escape Training

Overview

As part of their training and internal recruitment, HEMS (Helicopter Emergency Medical Service) paramedics with the National Ambulance Service (NAS) recently undertook Helicopter Underwater Escape Training (HUET). The course included instruction on the Compressed Air Emergency Breathing System (CAEBS) to ensure crews are prepared for rare water-landing emergencies.

Critical Safety Training

HUET is a mandatory safety programme for personnel flying over water. It equips paramedics with the skills and confidence to escape from a helicopter cabin in the unlikely event of a ditching or capsized landing.

Training is conducted in a controlled pool environment, simulating helicopter submersion scenarios. Participants practice emergency escape procedures, including using CAEBS equipment to provide critical seconds of breathable air while underwater.

Training Components

Key aspects of HUET for HEMS paramedics include:

  • Escaping from an inverted or submerged helicopter cabin
  • Using emergency breathing systems (CAEBS) effectively
  • Locating exits and windows in low-visibility conditions
  • Coordinating team-assisted escapes and maintaining calm under stress
  • Practising emergency procedures in realistic scenarios

Operational Significance

HUET is an essential part of HEMS paramedic recruitment and operational readiness. These paramedics deliver advanced pre-hospital care in challenging and remote environments, often via air ambulance. Completing HUET ensures they are fully prepared to operate safely in all conditions, including potential water landings.

Commitment to Safety

The rigorous training reflects NAS's dedication to crew safety and operational excellence. By investing in comprehensive underwater escape preparation, HEMS paramedics are better equipped to continue providing life-saving emergency medical services under high-risk conditions.
