The safe handling of chemicals requires an understanding of their properties, hazards, and measures for handling emergencies involving them. This information can be found on the compound's MSDS. This series of powerpoint presentations provides a variety of training resources to help you understand Material Safety Data Sheets and other Hazard Communications.
Preserving and maintaining evidence collected at a scene is crucial. The key is understanding evidence and understanding the proper way to package it. Package small items carefully or they could be lost.
Utility knives are one of the most common tools used in the work place, yet one of the most dangerous, especially in terms of the number and types of injuries produced.

In November 2007, Denver, Colorado, voters passed a $38 million bond to fund the redevelopment of the Denver Police Department's Crime Laboratory Bureau. The objective of the new Denver Crime Laboratory was to house all nine units under one roof, including two additional units that were previously at remote locations.
Lasers reliably work 24/7 in dusty, hot conditions and high ambient vibrations, retrieving latent prints and other trace evidence from a massive case load, often with 1000+ objects to be scanned per case.
Law enforcement’s move from pencils to pixels can be done quite easily. With careful planning and commitment, law enforcement agencies will begin realizing cost-saving results. Continued training and technology investments will encourage increased use of facial composites.
As shown by the King case, DNA identification gets results. DNA identification “is an extraordinarily effective tool for law enforcement officials to identify arrestees, solve past crimes, and exonerate innocent suspects.” DNA is the most reliable evidence of identification—“stronger even than fingerprints or photographs.”
Multitasking was once heralded as a fantastic way to maximize one’s time and get more done in a day. Then people started realizing that when they had a phone in their ear and were making calculations at the same time, their speed and accuracy (not to mention sanity) suffered. Rather than multitasking, try a new strategy known as “chunking.”
Touch DNA exists where a perpetrator has touched a surface at the crime scene, possibly leaving a fingerprint as well as DNA. Having the proper supplies on the scene, and the knowledge to use them, is critical to the collection of usable DNA samples.
One of the key lessons of improvisational comedy is the term “Yes, and.” The idea is that the actor accepts whatever comes at him and instead of fighting it, says “yes” to it. This really works in most business settings, too.

Most departments have one or two crime scene officers (CSOs) available. Their expertise is crucial, but in most cases, one or two CSOs are not enough to cover the whole territory the department is responsible for. Many departments are looking to evidence response technicians to solve the problem.
Well-formatted, clear, concise e-mail messages are critical to getting our messages read and getting the responses we need. But before you think about what you’re going to communicate in that e-mail, make sure e-mail is the best way to go.
According to the USGBC, decreased operating costs, increased property values, increased productivity, reduced absenteeism, improved risk management, and verified building performance are seen with LEED certified buildings.
The following describes a modified technique for obtaining tool mark impressions utilizing polyvinylsiloxane impression material. Advantages of the polyvinylsiloxane materials include ease of use, accuracy, and dimensional stability over time.
