• Pri 3 - No direct threat, public access or future development
• Pri 4 - No direct threat to life, no public access

Question 7

What lines and points are used to ensure a systematic EOC is conducted?

Answer 7

• Reference Point - An easy to locate feature to aid in locating the starting point (Datum point)
• Datum Point - The accurately surveyed and marked point to take all other references from.
• Datum Line - Predetermined bearing through the datum point.
• Start Points - Points along the datum line
• Start lines - Lines perpendicular from the datum line from the start points
• Intermediate Lines - Perpendicular to the start lines to box areas.

Question 8

What is the difference between a shallow and deep search?

Answer 8

• Shallow search depth is to 500mm. 2m search lanes
• Deep search is 500mm to 6m. 1m search lanes
