Safety Management • Hardware safety systems • Training • Safety through simplicity • Failsafe envelope • Examples: • Liquid nitrogen – better tools • Automatic retraction – eliminate confusion • Automatic backup – eliminate distraction

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
ADSC Quantum 210 Example 2: Automatic detector retraction
ADSC Quantum 210 Detector retraction
ADSC Quantum 210 Detector retraction
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! 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.
Safety Summary • Encourage safe practices by making them the best way to get results • Measures are in addition to existing ALS safety envelope • Better science and better safety can go hand in hand
