Be Safe: Don’t Store Flammables in an Ordinary Lab Refrigerator
Really, we should all “take all reasonable precautions to protect…employees, patients, students, and property against the danger of hazardous materials.” But some of us play a more critical role in that protection, such as the staff at Duke University medical facilities. That’s why the university safety manual includes a chapter on dealing with hazardous materials. It Read More

Getting Rid of Uninvited Guests of the Pestilential Sort
Let’s say you’re worried about insect or other pest infestation of a product being imported from a tropical country to a temperate one. You don’t want to introduce a potentially devastating pest into your ecosystem, so you want to get rid of anything that might be hitching a ride along with your product. You could Read More

When More Vaccinations Are Needed, Be Sure Your Storage is Sufficient
Luckily for us, public health standards constantly evolve. As new threats emerge, or more is learned about the effectiveness of existing practices, the lessons learned are applied. For example, the state of California recently enacted new standards for vaccination against pertussis. Specifically, “students entering or advancing into 7th through 12th grades will need proof of Read More

ICP-MS Verifies Safety of Food Supply
No one wants to sit down to a healthy meal of roast turkey and mashed potatoes covered in cadmium gravy with a sprinkling of lead. Environmental contaminants do get into our food, though, and only careful monitoring keeps the food supply safe. That’s the job of the USDA’s Food Safety Inspection Service, which is responsible Read More

Ultrasonic Cleaning One Way to Prepare Aerospace Surfaces for Inspection
There are few environments as rigorous as the aerospace environment. No, I take that back. There are NO environments as rigorous as the aerospace environment. It’s got everything: exposure to incredibly high levels of vibration, wide ranges of temperature and pressure variation, and exposure to all sorts of high energy radiation—gamma rays to alpha particles.

Dramatically Good Lab Practices
This video is worth watching for its Hans Zimmer soundtrack (don’t know where it came from, a Batman movie or Pirates of the Carribbean, probably), which introduces a whole new level of drama to pipetting. The un-narrated video runs through some good and bad laboratory practices, and even though we all know good practice is Read More

Platform Scale Validates Size Distribution of Construction Materials
Aggregate material properties are strongly influenced by the size of the constituent particles. For example, it’s way easier to make your bread dough homogenous if you first sift the flour. Same thing applies to construction materials, such as various forms of concrete. First thing you want to do is make sure of the size distribution Read More

Excessively Cold Vaccine Refrigerator Contributes to Influenza Outbreak
The television show “House” takes lots of poetic license with the medical profession (I just love it when the aggravated relative bursts into the glass-enclosed critical-care-unit and ends up getting spattered with blood and bile as a new abscess instantly forms and bursts), but it does provide some insight into the difficulty of disease diagnosis.

Weighing the Dangers of Naturally Occurring Asbestos
You’ve heard that asbestos is a health hazard, particularly when airborne. You know that remodelling projects need all sorts of air control and filtering if asbestos is present. But with the concern over asbestos in artificial structures and components, it’s easy to lose sight of the fact that asbestos is a naturally occurring mineral, and Read More
