WHAT ARE CONTRIBUTING FACTORS FOR AN RWC EXPLOSION? 

For there to be ignition of the gasoline vapor-air mixture, the following four criteria must be met:

1. An ignition source having adequate energy must be present

2. Amount of fuel-vapor must be present at a concentration within its flammability range (for gasoline the percentage in air is between 1.4% -7.6% in air

3. Ignition source must contact the fuel while it is in its flammable range

4. Contact between the ignition source and the fuel must be of sufficient duration for a transfer of energy to occur

As little as 1TBS (tablespoon) of gasoline fully evaporated within the engine compartment (sealed), can be enough to create a concentration of vapor in air which is within its flammability range, thus capable of causing an explosion.

This calculation is based on estimates of the average free air volume in a personal watercraft (PWC) engine compartment.

This is a social media account review of Personal Water Craft (PWC) explosions that have been reported and added to the Rescue Water Craft Association database. The information is gathered from around the world on the internet and collected into a concise snapshot of the incident. This is part of the RWCA Accident Reporting Program. If you have another incident to report, please send the data to info@RescueWaterCraft.org

ABOUT

The Accident and Review Program is an RWCA member and affiliate program that reviews mishaps, accidents, and near- misses from around the world to investigate these types of incidents and identify the root cause of the incidents. The goals of the Accident and Review Program are to be able to develop corrective actions for safety consideration that can help to prevent future mishaps.

To surviving family members and friends, the death of a loved one is tragic, and our sincere condolences go out to every person who has lost a loved one to a personal water craft accident. It is our goal to prevent these types of tragedies and to bring awareness to education and safety.

The investigative process is managed by a review process that organizes the collected criteria and submits the results to a panel of subject matter experts for review and consideration. Individual cases and ongoing or recurring incidents may be revised annually.

Three types of ARP formats:

1. Recreational

2. Occupational

3. Competition
