General Precautions

Assume that the electronic component is subject to electrostatic discharge (ESD) damage.

-Do not attempt to handle any electronic components using leather gloves.

Before cutting wires to components, insure component does not does not

have holdup RAM requiring power to maintain.

If the component is dry, keep it dry.

-Ship it “as is” to the component supplier or investigation lab.

-Do not attempt to scrub, brush, or otherwise mechanically remove dirt and debris from electronic components.

If the component is wet, keep it wet.

-If the electronic component is wet with mud or other material, treat it

il t t it

the same as a water-soaked board from a water crash site. Flush it with water and ship it in water.

Do not use any chemicals, such as bleach, to clean the component.

-This is critical for components with biohazard contamination.

Attempt to identify the types of electronics that the investigation team will focus on prior to going on-scene.

-Establish a priority listing for non-volatile memory

Be prepared to handle electronic devices prior to arriving at the accident site.
