5.0 Safety Summary

A comprehensive hazard risk assessment was carried out using two of the most
easily utilised techniques, SWIFT (Structured What If Technique) and a HAZOPs
(Hazard and Operability Study). These were carried out by recreating the typical
scenario for a powerboat race meeting. The hazard assessment commences when
the test driver is ready to enter the rig. This is the functionality of these boats and the
act of getting the boats to the point of launch is a matter for the HSE team within the
Osprey Powerboat Rescue Ltd. Company.

There were 8 hazards identified as being applicable to the functionality of these
immersion rigs and the end hazard level is indicated below along with the analysis
and proposed mitigations. For details of the hazards and their consequences and
mitigations please see Annex 2 - Hazard Log.

Haz 1: This hazard has been identified when the driver is entering the dunk rig as
being an area where the driver could be injured, however the Osprey Support
members are experienced and take care to embark drivers carefully. This
then becomes a low level Class C hazard.

Haz 2: This is probably the most common hazard which can happen any time a
support member or test driver embarks or disembarks the rig. There are a
number of obstructions to embarking and disembarking and experience of the
crew plus the care they provide when placing a test driver into the rig
mitigates this hazard to a low probability.

Haz 3: This hazard is possible but improbable given the training and expertise of the
support team and therefore is of a low level.

Haz 4: This hazard is a distinct possibility if it were not for the training and
professionalism of the support crew whose main job is to ensure the test
driver is observed at all times for difficult escapes. Again low level hazard.
Haz 5: For the cell to become separated from the support cage it would be either
metal failure or poor assembly. The rig is checked prior to every test and each
joint is checked prior to testing. Again low level hazard.

Haz 6: This hazard happens on occasions however the support team will observe
the driver's difficulties and effect a rescue in good time to prevent injury. Again
low level hazard.

Haz 7: High pressure compressed gases are dangerous and could initiate a high
speed projectile or cause a blunt force trauma or an air embolism. Only
personnel who are experienced in high pressure gas charging and use are
allowed to charge air cylinders and training and experience with diving
cylinders is essential for all team members.

Haz 8: As in Hazard 5 the structure is scrutinized prior to testing and again after
assembly. Low level hazard.
