The first responding officer may be called upon to transport evidence from a crime scene.They should be aware that direct sunlight and warmer conditions may degrade DNA, and avoid storing evidence in places that may get hot, such as the trunk of the police car. To best preserve DNA evidence, store in a cold environment.
Chemical safety begins with a good working knowledge of the chemicals you use and their hazardous properties. When incompatible materials contact each other, the result can lead to explosion, the evolution of toxic or flammable gas, or both.
Before considering money saving solutions for energy efficiency, the laboratory must first be designed for the safety of its occupants. Fume hoods are the major line of defense in the utilization of chemical hazards in a toxicology laboratory. By definition, fume hoods are not energy efficient, but their inefficiency serves the purpose of safety.
There are several common problems that crime scene evidence technicians and detectives encounter. One such problem is that of preserving fingerprint evidence on rough surfaces, human skin, blood prints, and curved surfaces. Hard to lift prints can be accomplished by using magnetic powder and casting silicone.
As a manager, there are many opportunities to share good news, recognize staff members for accomplishments, and to enjoy a few moments focusing on a job well-done. However, not all news is good news and, unfortunately, delivering bad news is part of the job.
You need to know what you have and where it's located. Whether you decide to do it with sheets of paper, index cards, or computers, you need to have a chemical inventory. It's pretty hard to comply with OSHA and EPA regulations without one. It's pretty hard to know what to order without one.
Working dogs’ success is far from a given: It takes imagination, deep knowledge, and constant work to train and handle dogs who work with their noses for a living. These are the dog people whose lives and careers are so interwoven with working canines that it can be difficult to see where the person ends and the dog begins; they complete each other.
Let’s take a look at what you need for basic fingerprint kit. This kit should include different types of powders and brushes to identify prints on different surfaces. When working with any of the powders, you need disposable dust masks and nitrile or latex gloves. You also need a small hand-held magnifier to view the prints.
The telephone interview or candidate screen allows the employer to determine if the candidate's qualifications, experience, workplace preferences, and salary needs are congruent with the position and organization. The telephone interview saves managerial time and eliminates unlikely candidates.
Employers are responsible for providing personal protective equipment (PPE) such as safety glasses, goggles, face shields, gloves, lab coats, and bench top shields. Employees are responsible for using these devices. The employer has an additional responsibility. The employer needs to make sure that the PPE is used.
The courts have generally accepted evidence collected from the Internet as long as its authenticity can be established. Following the current methodology and the lessons learned from the field of traditional digital forensics, a standard can be developed for the collection of Internet based evidence.
The ways in which we handle our goof-ups, guffaws, screw-ups, bad decisions, miscalculations, and blunders are critical—our reputations are at stake. And as managers, we should role model the behaviors we seek in others. Here are 10 ideas on how to react to and recover from mistakes.
Continue reading to learn how to develop training that will keep your attendees interested and focused. These seven guidelines will walk you through the entire process from development to delivery then loop back through evaluating and improving your training programs.
Quick screening systems can now allow us to select the most appropriate forensic samples for full DNA analysis. Eliminating evidence that will not generate a useful DNA profile early in the investigative process saves time and money. Using an effective DNA screening system allows crime laboratories to focus on evidence that will generate a useful DNA profile.
Through visual examination or advanced chemical analysis of inks and paper, forensic investigators can determine information relating to a questioned document's authentication, authorship or creation date. During the analysis of these documents, investigators must be careful not to destroy the evidence.
