Before a cell divides and DNA is passed from one cell to another, a complex process occurs. The DNA strands unwind and separate. Each strand makes a complementary strand by adding the appropriate nucleotides. As a result, there are now two double-stranded DNA molecules in the nucleus that contain the same information. This process is known as replication. This animation will describe the complex process in detail.

Video Transcript -
The cost of quality is more than a management tool. It’s a mindset that should be adopted at every operational level of a laboratory. The implications and cost associated with poor quality, or no quality, create ripple effects well beyond the walls of your laboratory. Adopting a cost of quality mindset helps improve all laboratory operations, which include reducing processing and testing errors and decreasing avoidable expenses that result from having to repeat the work. A laboratory pays for prevention once; however, it pays many times over to resolve recurring problems.
Video Transcript -
Investing in a QMS will help your laboratory efficiently manage organizational assets, quantify the value, and impact a QMS brings, and identify opportunities to continuously improve your laboratory’s mission.

It’s important to report and record all incidents, even near misses, to ensure risks are properly assessed and mitigated. In this video, an animal researcher has a sharps incident during which they puncture their skin with a needle after removing the needle from a research animal. Is this considered an incident or a near miss? Should this situation be reported?
Video Transcript -
Biological, chemical, and physical hazards can put laboratory employees at risk for safety incidents that could injure themselves, fellow employees, the public, and the environment. To lower risk, each laboratory should promote a culture of safety in which laboratory safety issues are immediately addressed and consistently assessed. Laboratory employees should be trained in best practices that are outlined in the laboratory SOP and exposure control plan. These administrative controls are assessed annually or reassessed after an incident or near miss. Together these safety measures contribute to a culture of safety that helps to lower risk for laboratory employees, the public, and the environment.
Video Transcript -
Laboratory employees are at risk for coming into contact with biological, chemical, and physical hazards in their daily work.

A laboratory incident, such as a sharps injury, could cause an employee serious harm or exposure to a dangerous pathogen. A near miss is an incident that doesn’t result in an injury or exposure, it’s called a near miss. It’s important to report and record all incidents, even near misses, to ensure risks are properly assessed and mitigated. In this video, an animal researcher has a sharps incident during which they puncture their skin with a needle after removing the needle from a research animal. Is this considered an incident or a near miss? Should this situation be reported?

Biological, chemical, and physical hazards can put laboratory employees at risk for safety incidents that could injure themselves, fellow employees, the public, and the environment. To lower risk, each laboratory should promote a culture of safety in which laboratory safety issues are immediately addressed and consistently assessed. Laboratory employees should be trained in best practices that are outlined in the laboratory SOP and exposure control plan. These administrative controls are assessed annually or reassessed after an incident or near miss. Together these safety measures contribute to a culture of safety that helps to lower risk for laboratory employees, the public, and the environment.

Laboratory employees are at risk for coming into contact with biological, chemical, and physical hazards in their daily work. As part of OSHA’s bloodborne pathogens standard, laboratories must follow certain guidelines to identify risks in the laboratory and do what they can to lower these risks. A hierarchy of safety controls should also be in place to mitigate risk. This video presents a scenario asking how new laboratory employees can find out what hazards are present in their laboratory.

Working in a laboratory can put an employee at risk for coming in contact with biological, chemical, and physical, and electrical hazards. In this video, a laboratory technician heats an unlabeled solution using a hot plate that is connected by a long extension cord to an outlet on the other side of the laboratory. The technician leaves the solution unattended, and another employee happens to trip over the cord, knock over the solution, and burn their hand on the hot plate. What were the circumstances leading to this incident and how could it have been avoided? What are some best practices for maintaining laboratory safety in this situation?

Directional airflow in the laboratory is an engineering control that keeps possibly contaminated air in a laboratory from reaching other areas. The constant influx of air directs flow through biological safety cabinets and fume hoods where the air can travel through filters. In this video, a laboratory technician notices that the flutter tape, indicating the direction of airflow, is showing that air is moving out of the laboratory instead of into the laboratory. What should this technician do next?

Standard operating procedures (SOPs) are administrative controls that help reduce risk from harm by identifying hazards in the laboratory. An SOP usually outlines best practices, procedures, and guidelines for laboratory employees, while keeping track of regular risk assessments, training, and incidents. In this video, an employee is tasked with using a new procedure. When they look up the SOPs and risk assessments that are available, they find that the new protocol may have additional risks. What should they do next?
