Concept
Biohazard safety levels, also known as biosafety levels (BSL), are a series of protective measures required to isolate dangerous biological agents in an enclosed laboratory facility, ranging from BSL-1 to BSL-4. Each level corresponds to the degree of risk posed by the agents and the necessary containment and safety practices to prevent exposure to humans and the environment.

Containment is a geopolitical strategy aimed at preventing the expansion of an adversary's influence, often used during the Cold War to limit Soviet power. It involves a combination of military, political, and economic measures to maintain the status quo and protect national interests without direct confrontation.
Concept
A pathogen is a biological agent that causes disease or illness to its host, disrupting normal physiological functions. These agents include bacteria, viruses, fungi, and parasites, each employing unique mechanisms to invade and damage host tissues.
Concept
Laboratory safety is the practice of minimizing risk and preventing accidents through proper protocols, equipment, and behavior in a lab environment. It is essential for protecting personnel, ensuring compliance with regulations, and maintaining the integrity of scientific research.
Concept
Infectious diseases are caused by pathogenic microorganisms such as bacteria, viruses, parasites, or fungi, and can be spread, directly or indirectly, from one person to another. They pose significant public health challenges due to their potential for rapid transmission and the emergence of drug-resistant strains.
Concept
Risk assessment is a systematic process of evaluating potential risks that could negatively impact an organization's ability to conduct business. It involves identifying, analyzing, and prioritizing risks to mitigate their impact through strategic planning and decision-making.
Personal Protective Equipment (PPE) is essential for minimizing exposure to workplace hazards that can cause serious injuries and illnesses. It acts as a barrier between the wearer and potential hazards, ensuring safety and compliance with health regulations.
Concept
Decontamination is the process of removing or neutralizing contaminants that have accumulated on personnel, equipment, or surfaces to prevent the spread of harmful substances. It is a critical component in maintaining safety and hygiene in healthcare, industrial, and environmental settings.
Concept
Concept
Safety protocols are structured guidelines designed to minimize risk and ensure the well-being of individuals in various environments, such as workplaces, schools, and public spaces. They are essential for preventing accidents, managing emergencies, and maintaining compliance with legal and regulatory standards.
Concept
Microbiological practices encompass the techniques and protocols used to safely handle, culture, and study microorganisms in laboratory settings. These practices are essential for preventing contamination, ensuring accurate experimental results, and maintaining biosafety standards.
Concept
A biosafety cabinet is a ventilated laboratory workspace designed to protect the user, the environment, and the material being handled from exposure to biohazards and cross-contamination. It achieves this by using HEPA-filtered airflow, creating a sterile environment and maintaining containment of potentially harmful agents.
