3 Initial Site Investigation Lesson 7 Objectives Understand the significance of the initial site investigation. Prepare the team with the necessary equipment and information for a safe and successful site survey. Conduct the initial survey and determine how it should be approached by the team. Control the accident site to help ensure that evidence is not disturbed so it can be collected and documented correctly. 3

4 Initial Site Investigation before we get started... What do you expect to get from it? What should you be aware of? What should you be cautious about? Who should enter the site? How important is the visit? 4

5 Successful Visit First Priority: Prevent further loss of life, injury, or property loss. (This includes you!) 5

6 Site Controls The accident site must be secured and safety hazards identified or mitigated prior to entering or visiting the site. 6

9 Site Controls Contact agency or local law enforcement to ensure that any available preliminary investigation information and/or special interest in the incident are known. 9

10 Initial Site Investigation Any site security procedures that had been established prior to the SAIT arrival should be understood and the Team Leader should coordinate with the Agency Administrator for continued site security as necessary. 10

11 Site Controls The entire accident site needs to be controlled and the evidence protected until it is released back to the unit by the Chief Investigator. 11

12 Site Controls Contact agency or local law enforcement to ensure that any available preliminary investigation information and/or special interest in the incident are known. If there is evidence that may be easily disturbed the chief investigator and team leader should consider controlling access. Controlling the accident site. People not assigned to the SAIT or not invited to the site should be prohibited from entering by the Chief Investigator. 12

13 Initial Site Investigation Lets look at handout 7-1, the Initial Site Investigation Checklist 13

14 Approaching the Accident Site Prepare equipment and people Use the Checklist we just reviewed! Approached the site as the workers did STOP...and view the entire scene 14

15 Initial Site Investigation Initial Site Investigation At the Site Approach the site slowly and deliberately Get an overall look at the accident area before more evidence is disturbed. Landscape features, shadows, roadways, space allocation, type/location of equipment and people, etc., should all be looked at from a distance to help establish the overall complexity of the scene or workplace. Try to get the overall picture of what was going on Established the flow and main task of the work. Establish where the impact or contact that caused the injury or damage occurred. Start to think about what evidence you want to gather first. If there is evidence that may be easily disturbed, only the chief investigator and team leader should enter the area. 15

16 Initial Site Investigation Initial Site Investigation At the Site Attempt to establish the conditions at the time of the accident. Its helpful to review the accident site at the same time of day that the accident happened. Take into consideration the weather or other environmental conditions that may have been in play at the time of the accident. The extent of the accident site. The physical dimensions should be established and the boundaries identified and marked if necessary. 16

17 Initial Site Investigation Initial Site Investigation At the Site The description of the site needs to be prepared very carefully at the site to ensure that it is accurate and well defined: drawings, photographs, historical records, etc., all may prove useful 17

18 Initial Site Investigation The Chief Investigator has control of the accident site and the accident site should be approached slowly getting the overall picture of what was going on and what the conditions were at the time of the accident. The Chief Investigator will establish: Who needs to go to the accident site What main tasks need to be done Order in which tasks should be done Who will do tasks The extent of the site Site security and entry requirements, if any Initial description and mapping of the site Photographs of everything before they are touched Collection of evidence Logging of evidence and photographs- Anything taken from the accident site needs to be logged in on the evidence log so the chain of custody is established 18

19 Initial Site Investigation Contamination Of The Site The Chief Investigator should always consider the likelihood that the site has been disturbed when considering the position of evidence. If the site has been disturbed, witnesses should be used to determine how the site looked at the time of the incident or how it typically looks during a similar operation. 19

20 Initial Site Investigation Reality Check Are you or your team members ever going to be the first ones at the scene? Was the scene secured before you arrived? Have things been moved? 20

21 Initial Site Investigation Be prepared Be deliberate Be thorough Be cautious 21
