4. GENERAL PRECAUTIONS

4-1 Only those personnel actively engaged in performing or witnessing this test shall be permitted in the testing area.

All specified safety regulations shall be strictly observed.

4-2 To prevent injury or death, ensure that certified test equipment is used during testing.

4-3 Safeguarding of personnel and equipment shall be adhered to at all times.

4-4 Never open the cap on the engine coolant system when the engine is hot (greater than 120°F). The system may be pressurized and contain coolant at temperatures which will cause severe burns.

4-5 Do not move the craft until all ground personnel have cleared the immediate area. Personnel in the surrounding area may be injured or killed if struck by the craft.

4-6 Do not move the craft until all personnel are securely onboard or have cleared the immediate mooring area.

Personnel in the surrounding area may be injured or killed if struck by the craft.

4-7 Personnel onboard the craft should be notified that transition from the land to water is in progress and from water to land is in progress. This notification will allow personnel to prepare for turbulence and the abrupt speed reduction when the front wheels become grounded. Failure to provide notice may result in serious injury or death to onboard personnel.
