Ever since I built the Earth Defense HQ (#7066), I've had a Haz-Mat collectible minifigure at the helm of the small support vehicle that comes with the set. The little guy just seemed like a perfect fit with the theme. I recently bought another Haz-Mat guy and decided they needed some gear, so I built a unit that can be attached to the trailer of the support vehicle.
This a a small vignette I made to show the Haz-Mat crew in action. An alien saucer (from set #7066) has crashed into the street and the crew, led by the ADU Scientist (also from set #7066), is on the scene.
Below are some pics of the support vehicle with Haz-Mat attachment away from the vignette...
The crew has a number of tools at their disposal including a sampling device, a probe, a shovel and a vacuum system.
Lastly, the Haz-Mat attachment off of the trailer...
