Overtime Risks

The following is straight from Circadian Technologies’ news email. More Evidence on the Risks of Overtime Research from the University of Massachusetts shows a strong link between working overtime and sustaining a work-related injury. This was found to be true for all occupations, not just those that were physically demanding or in dangerous industries. Of […]

Participate and Be Rewarded

I have worked closely with Circadian Technologies. Inc. over the past years. This includes losing some sleep in their Sleep Lab. I have to admit though, Dr. Ted langley did the hard part and stayed up all night with subjects being tested. Circadian represent one of the best resources in the country for information about […]

Crossing Guard Fired

The following story from the Houston Chronicle, which was picked up on NPR, is another reminder of how pervasive urine testing is becoming. Readers of this blog already know that I am not in favor of the use of drugs, but it is worth repeating that I am not. Nor am I against using urine […]

Accidents caused by tired drivers may actually be much higher: determining whether fatigue played a role in a crash […]

The Long Drive Home

While we stress the importance of pre work testing, it may be that post work testing is even more important. In some jobs […]

O Rings and Friendly Fire

Does sleep deprivation cause accidents? Of course not. But it is often a contributing cause. Too often. Could testing help reduce these kinds of accidents? In some cases – yes, it certainly could. A culture of awareness and responsible testing could have helped in the Challenger accident. On the battle field, I am not so […]

Shapes Used for a Test

Our entry of 2/5/05 spoke about the use of visual challenges for alertness testing. In response to requests for examples of shapes used in the BLT Alertness Test, here are a few. Obviously, these are very simple images, but they are sufficiently challenging when presented in groups of similar images (each row represents a similar […]

New Tests

The basic BLT Alertness test uses a set of shapes on the white squares of a small checkerboard. The challenge is to determine if all the shapes are the same or not. Since some of the shapes look similar and are randomly rotated, it can be difficult to tell if they are actually all the […]

A Pill for Alertness?

I talk a lot about alertness and its importance to safer work. And we emphasize getting enough sleep and eating properly. But what if it turns out that a simple pill will keep you alert? What if a pill can improve your memory? Well it seems, such medications are not that far away. In a […]
