Safety Envelope “There is no safety system that can stop a determined user with a hacksaw” -Anonymous Solution: Create tools that enhance productivity within the safety envelope

Detector retraction ADSC Quantum 210
27
Automatic detector retraction Detector motors are disabled with hutch door open (pinch hazard) Sample is difficult to access with detector in data collection position Common mistake: –forget to retract detector before opening door Result: confusion Solution: –Door will not open with detector forward –Detector automatically retracts on door open attempt

Distraction is unsafe! 0.8 1.0 1.2 1.4 1.6 1.8 2468 Distance from the lead vehicle (secs.) Median time to lift foot off accelerator (secs.) Distraction Condition No-Distraction Condition 0.8 1.0 1.2 1.4 1.6 1.8 2468 Distance from the lead vehicle (secs.) Median time to lift foot off accelerator (secs.) Distraction Condition No-Distraction Condition Drivers following a car that suddenly brakes take longer to respond to that event when they are distracted by trying to solve a logic problem. This is especially true if the two vehicles start out close together--when it is critical that the driver in the following vehicle make a rapid response to avoid a rear-end collision.
