I am an biologist so I know what I'm talking about. And I'm talking about labs and security. There are certain rules that you learn on your first day after donning the lab coat and entering ANY lab. One of them is: Cover your body. When you are in a lab, be it chemical or biological, you wear a coat. That's to protect you from harm. So don't ever go into a lab with more or less harmful agents with a T-Shirt or a skirt or sandals. NEVER. And that goes even for you run-of-the-mill school lab.
Now...in this episode we have a biological warfare research lab stuffed with all the baddies from anthrax to an engineered supervirus. Every sane person would call that a lab with biosafety level 4, that's the highest possible level. If you feel lucky you can call it a level 3 facility doesn't really matter in this case. Because in both you have some pretty high standards concerning storage, handling, and access. And concerning appropriate personal protective clothing. You remenber the movie "Outbreak"? That was the same level. All those science guys stompüing around in their own personal one-man coverall haz suits looking like astronauts. THAT is how you do it. You NEVER handle a potentially very dangerous agent just protected by a pair of rubber gloves and a strong will not to get infected. That's how people die, quickly. Those people don't become scientists, they become corpses. It's called evolution. To get your (very well protected) hands on such a vial you will pass through at least two airlocks with higher pressure on the outside and a special shower with aggressive chemical agents, UV light to kill any virus/bacteria. NOBODY will ever lay hands on those vials outside this room and without proper protection, even IF there were such a thing as an unbreakable container. Even if those little suckers were encased in big block of Cantbedestroyedium. That's how it works, even in small labs with no kill-you-all virus. Even the CDC person did some incredible handling (without gloves) while a whole bunch of civilians stood around him. And he really called a fridge with a glass door a "safe"...LOL
The worst thing is...it could have worked with a more realistic view of a level 4 lab. A few tweaks here and there, a hole in the hazmat suit, a contaminated needle on the door knob, you name it. Probably the writer had no clue about labs in general and no interest to face reality and kill his little unrealistic plot. Sorry, 8-9 points for Jane, but with that faulty plot a 3 has to suffice.
