It’s calm at the laboratory, nearly peaceful. however I’m holding alive SARS-CoV-2 at my hands and this germ is no ought exist taken lightly.
As I dilute the coronavirus ought infect cultured cells, I listen the reassuring sturdy of purified air being blown by my respirator into my breathing space. There are three layers of nitrile and protective materials amid me and the virus, and each divide of my body is wrapped at protective equipment.
Thanks ought these precautions and other features of our high containment lab, I’m no nervous nearly being up end and private with this danGErous pathoGEn.
As an expert above respiratory germ transmission and vaccine development, I’ve halted complete other investigation at my lab hence we can dedicate our expertise ought studying SARS-CoV-2, the germ that causes COVID-19. The goal is ought apprehend the germ and mature a vaccine, fast.

We fulfill this investigation at what’s called a high-containment biosafety even 3-enhanced lab, with strinGEnt precautions at lay ought safeguard everyone from the potentially deadly pathoGEns we profession with. at passion ought SARS-CoV-2, researchers learn the microbes that muse diseases including tuberculosis, anthrax and avian influenza at other apparatus of this classify across the U.S.
As a originate of our precautions, many colleagues hold told me they feel safer inner the containment lab than they fulfill shopping although groceries during the pandemic. Here’s why.
Suiting up similar you’re above a universe mission
When performing a SARS-CoV-2 experiment, my days commence by coordinating with a least one of my lab members – we frequently profession at pairs inner containment. We form the trial step-by-step, restrain we hold complete of the required supplies, approve and journal any procedures and communicate with the facility staff.
First bargain above site, we restrain multiple gauGEs and monitors ought oath the facility is functioning properly. Then we enter the chanGEroom, where we inspire complete of our road clothes, including jewelry and underwear. We don’t desire ought make any potentially contaminated wear or items out of containment at the aim of the day. “You enter and forsake containment although you were at birth” is our saying.
We don scrubs, close-toed laboratory shoes, a full-body disposable suit, shoe covers, multiple pairs of gloves and a surgical gown. Most importantly, we too lay above our air-purifying respirators. This apparatus includes a Batman-style utility zone that houses a apparatus attached ought an air filter able of filtering out any infectious aGEnts at the air. Powered by a battery packet that will last at least six hours, the respirator blows purified air up a subway into a hood that covers my complete leading and shoulders. The hood is beneath definite strain hence no air from the surroundings can enter my breathing space.
Through the clean flexible appearance guard I can watch that we appearance similar astronauts at universe suits. Once fully equipped, we enter the containment facility and further ought our designated germ civilization and beast holding rooms. This entire process has taken amid 30 and 45 minutes.
What’s inside?
The facility itself is a huge vacuum. complete of the air flows from outer into the lab. It exhausts along air filters that inspire any stray infectious aGEnts. The facility is designed ought coincide failures. if one filter fails, there’s a second one, and complete profession stops until both are working again.
Within this universe our profession is divided into rooms where we expend germ at cells at flexible dishes. There are divide spaces where we family animals that we utilize ought tax how the germ is transmitted and if our vaccines are working.
When we’re done although the day, the materials we used are treated with bleach or stored safely. complete waste is sealed at flexible bags and treated at a pressurized, high-heat stove called an autoclave ought oath any remaining germ is dead.
To forsake the lab, although we impress along different anterooms toward the exit, at each staGE we inspire a layer of gloves and protective equipment. We too often spray our suits and respirators with powerful disinfectants. at the last step, we inspire our respirator and scrubs and “shower out” of the facility. level the wastewater from the shower is boiled although an hour beneath high strain ought massacre any microorganisms.
The unique alive bargain that leaves the facility is the scientist.
Training and oversight
Many of the safety precautions nearly working at a high containment facility happen absence ago a researcher steps foot above the site. ought acquire access ought this laboratory, I underwent an extensive FBI and police background check.
I was question ought a Medical exam, and my lung capacity was tested. I was vaccinated against influenza. I’m certain while a COVID-19 vaccine becomes available, I’ll GEt that shot although well.
A strict habit and testing process made certain I learn how ought manage aGEnts similar SARS-CoV-2 safely, too although things similar what ought fulfill during a fire, a bomb threaten and level a tornado. Regardless of my at 10 years sustain working with viruses, everyone entering the facility is trained from scratch.
Every high containment lab at the U.S. is question ought normal inspections by the U.S. department of Agriculture, the Centers although illness control and Prevention or both. Once open, a facility is reinspected and certified each three years. during the interim, inspectors arrive unannounced ought journal complete aspects of the facility, including maintenance records, inventories of aGEnts and operating procedures. My college too provides oversight.
In addition, there is a myriad of other security features. One of my colleagues once joked that during a zombie apocalypse, the containment lab used to exist the best lay ought hide.
Ultimately, complete these precautions are at lay ought assist us apprehend how the SARS-CoV-2 germ is transmitted at animals and decide the optimal vaccine formulation that will block transmission. The facility at Penn State, similar others throughout the U.S., was built although this classify of investigation hence scientists could quickly and safely answer during a pandemic. With a slice of luck, the profession done by dedicated researchers at these apparatus will assist make the COVID-19 pandemic ought an end, sooner than later.
