Crime Scene Photography: Equipment

January 22, 2015 7:46 am | by Dick Warrington | Articles | Comments

Before we look at the specifics of crime scene photography, let’s consider the equipment you’ll need. Keep in mind that you don’t need the most sophisticated and most expensive camera on the market. Every department has different equipment these days.

The NFL has 32 teams, not groups. Teams. All teams are groups, but not all groups are teams. Calling a group a team doesn’t make it one. That’s the team myth. Too many business owners and executives think of “team” as a label. It’s not. A “team” is an ach

The Team Myth: 5 Steps to Successful Team Building

The NFL has 32 teams, not groups. Teams. All teams are groups, but not all groups are teams. Calling a group a team doesn’t make it one. That’s the team myth. Too many business owners and executives think of “team” as a label. It’s not. A “team” is an achievement; a dynamic process that includes talent, focus, motivation and sacrifice. It has a personality, preferences and a unique culture.

Since evidence can take over 24 hours to dry, the ability to secure evidence with a lock or tamper-proof tags is critical in maintaining the chain of custody.

Most of us know you should attempt to develop latent prints as soon as possible. When latent prints are deposited on a surface, nearly 99% of the print is composed of water. The water begins to evaporate and the print dries out. For this reason, it is ess

Safe Storage of Flammable and Combustible Materials

December 18, 2014 9:39 am | by Vince McLeod, CIH | Articles | Comments

Safely storing flammable and combustible liquids in laboratories or stockrooms is risky business. However, by paying attention to the hazard class of the material, the largest container size and the total quantities we can minimize that risk. In addition, here are some general guidelines for safe flammable and combustible storage.

More Bits about Areal Density

December 12, 2014 11:55 am | Articles | Comments

At first glance, it would seem that the most logical and obvious way to increase storage capacity would be to add more platters to a hard drive. However, this raises a number of inherent problems, such as having to increase the size beyond the current form factors (3.5”, 2.5”, etc.), escalating the cost per hard drive, having to have more read/write heads per hard drive, and so forth.

The National Fire Protection Association’s (NFPA) Code for Flammable and Combustible Liquids, NFPA 30, is an excellent resource and introduction to the hazards of these materials. Without getting too bogged down in technical details, there are a few conce

The National Fire Protection Association’s (NFPA) Code for Flammable and Combustible Liquids, NFPA 30, is an excellent resource and introduction to the hazards of these materials. Without getting too bogged down in technical details, there are a few concepts that need mentioning and understanding at the outset.

Hard Drives 'Spin' into the Future

December 5, 2014 9:14 am | Articles | Comments

To increase hard drive storage capacity, manufacturers have been able to decrease the size of magnetic grains which comprise data bits. This allows for a greater number of bits of data to be recorded. However, the grains are so small that they can potentially interfere with each other. This diminishes their ability to maintain assigned magnetic orientations and data would become corrupted, leading to an unreliable and unusable hard drive.

Organize Your Crime Scene to Avoid Contamination

When you arrive at the scene, establish secure, central areas for clean equipment, items to be disposed of, and items to be decontaminated. For the first area, I used to take a clean biohazard bag, open it up, and spread it on the ground.

How to Ace Your Performance Review

Typically, managers dread having to perform employee assessments and experience high anxiety anticipating them. For the employee, too, who is about to undergo a formal performance assessment, the procedure is a high-anxiety producer. So what typically happens is that two very nervous people get together, try to act calm, and just “get through it.” It doesn’t have to be that way.

Evidence: Know What to Look For

November 26, 2014 4:49 am | by Dick Warrington | Articles | Comments

As I've mentioned before, understanding what is possible—not just by you, but by others—is crucial. Prints are a good example. In the past, we couldn’t lift prints from certain surfaces. Now, experts can lift latents from documents, papers, and adhesive tape.

How Should a Lab Safety Audit be Conducted?

November 25, 2014 5:02 am | by Vince McLeod, CIH | Articles | Comments

This apparently innocent question may be the one you agonize over the most. Personally, we feel there is no substitute for face to face interviews and a physical walk through of each laboratory. The crucial thing here is that the auditor or surveyor must be trained and knowledgeable about the type of work being performed in the laboratory undergoing the safety audit.

Why Employees Quit: Frustration about Co-workers

When someone says I don’t like my job, there’s little hope of retaining that employee, right? Not necessarily, there’s a fair chance that 1) I don’t like my job reflects feelings of discontent rather than a clear picture of dissatisfaction, and 2) a decision to leave would be premature.
