Understanding Biosafety Levels
Biosafety levels protect lab workers and the public from dangerous germs.
They range from basic to very strict rules.
Each level has special equipment and ways of working.
The Basics of Biosafety
Biosafety levels are rules for working with germs in labs.
They help keep people safe.
There are four levels, called BSL-1, BSL-2, BSL-3, and BSL-4.
Each level has more rules than the one before.
The rules say what clothes to wear and how to handle germs.
They also tell labs what safety gear to use.
BSL-1 is for safe germs.
BSL-4 is for the most dangerous ones.
Labs must follow the right level for the germs they study.
Levels BSL-1 to BSL-3
BSL-1 is the most basic level.
It’s for germs that don’t make healthy people sick.
Labs use simple safety gear like gloves.
BSL-2 is a step up.
It’s for germs that can make people a little sick.
Labs use safety cabinets to keep germs contained.
BSL-3 is for germs that can make people very sick.
These labs have special air systems.
Workers wear protective suits.
• BSL-1: Safe germs, basic rules

Design and Safety Features of BSL-4 Labs
BSL-4 labs have strict safety measures to protect workers and prevent pathogen release.
These labs use special air systems, cleaning methods, and protective gear.
Airflow and Filtration Systems
BSL-4 labs use advanced air handling systems to keep dangerous pathogens inside.
The air pressure inside is lower than outside.
This stops contaminated air from escaping.
HEPA filters clean all air leaving the lab.
They remove 99.97% of tiny particles.
The lab has backup power to keep air systems running if the main power fails.
Air flows from clean areas to dirty ones.
This protects workers as they move through the lab.
Sensors monitor air pressure to make sure it’s working right.
Decontamination Processes
BSL-4 labs use strong cleaning methods to kill germs.
All waste is treated before leaving the lab.
Chemical showers clean the outside of protective suits.
Workers must shower with soap when exiting.
This removes any germs on their bodies.
Labs use autoclaves to sterilize equipment with high heat and pressure.
Some use vaporized hydrogen peroxide to clean whole rooms.
Liquid waste goes through special treatment before disposal.
Solid waste is put in sealed containers and burned in an incinerator.
Safety Equipment and PPE
Workers in BSL-4 labs wear special gear for protection.
Full-body, air-supplied suits keep them safe from dangerous germs.
