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.
