went into the room, we passed through an additional security system that won’t be described here.
In the end, I never found out what role the commander had in my visit to Level 4. But I think he must have known about it. Jeremy and Martha were experienced, cautious professionals with impeccable safety records. I speculated that the commander had decided to permit me to visit Level 4 with these two people, so long as the visit was kept low-key—though not unofficial. The main building of USAMRIID had security guards who sat in a control room, monitoring the movements of people in the building. I guessed that the security people had known that I would be going into a hot zone even before I knew it myself. The magnetic security card that I wore clipped to my shirt could show the security staff my location in the building; it would also tell them that I was entering the hot area.
The locker room was small and gritty-looking, with a wooden bench and some steel gym lockers, banged up and dented. Jeremy and I stripped down to nothing and put our clothing in the lockers.
“You need to take off your glasses and leave them, too,” he said. “They’d fog up inside the suit, anyway.”
People had to take out contact lenses, as well. They also had to remove jewelry, including engagement rings. (Women were allowed to wear a tampon in Level 4, but they had to remove it on their way out of the lab.)
I put my glasses in the locker. As I took off my shirt, I slipped the notebook out of my pocket, and I clipped the mechanical pencil to the notebook. Holding these two items, but otherwise stark naked, I followed Jeremy through a doorway that led inward.
The doorway was actually a tiled shower stall, with a water shower-head in it and a drain in the floor. The shower stall glowed deep purple with ultraviolet lights. On their way out of the hot zone, after having worked in a space suit with dangerous organisms, the researchers would pass naked through the water shower, washing their skin with detergent and bathing their bodies in ultraviolet light, before they went into the locker room to get dressed.
On the inward side of the ultraviolet doorway was a small room considered to be at Biosafety Level 2—the mildest degree of biocontainment. Some metal shelves stood against one wall, and there was a toilet. The shelves were piled with blue cotton surgical scrub suits and other items of surgical wear, along with rolls of tape. We put on scrubs—no underwear was allowed. We also put on white socks, surgical hair coverings, and surgical gloves. Jeremy showed me how to tape the socks and the gloves to the cuffs of my scrub suit, wrapping the tape around the cuff to make a seal. “It’s a good idea to empty your bladder,” Jeremy said. “You won’t get a chance to once you’re in a suit.”
I took up my notebook and pencil, and we pushed through a door into Level 3—this was a staging area leading to Level 4. It was a large room with cinder-block walls and a concrete floor. We heard a rumble of air- filtering machinery overhead. The staging area was crowded with pieces of laboratory equipment. Along the left- hand wall hung an array of biohazard space suits. They were made of soft blue plastic, with flexible plastic helmet hoods. Most of the suits had the owners’ names written on them with a Magic Marker.
“People are touchy about their suits,” Jeremy remarked. “It’s like the Three Bears: ‘Somebody’s been wearing my suit.’”
Martha had already donned her space suit, and she was preparing things in the staging area. While Jeremy got into his suit, Martha took a space suit down from the wall and helped me put it on. She opened the suit, peeling apart a sort of large Ziploc-style zipper that ran across the chest, and handed the opened suit to me.
There was no name on my space suit.
I sat down on a bench and slipped my feet through the chest opening, down into the suit’s legs. My feet ended up inside a pair of soft plastic bunny feet attached to the suit’s legs. I drew the suit over my body, and slid my arms into the sleeves, and into heavy rubber gloves attached to the ends of the sleeves.
I pulled the hood and faceplate down over my head. The space suit’s zipper ran diagonally across the chest. I sealed the zipper, running my thumb and fingers along the seal, which closed me into the suit. The zipper was coated with a kind of grease that felt like Vaseline. The seals made a lip-smacking sound as I squeezed the zipper shut.
A number of bright yellow air hoses dangled from the ceiling. They were the source of clean air for people’s space suits. Each room in the hot zone had its own set of air hoses hanging from the ceiling. When you moved from one room to another, you had to detach your air hose and get connected to a different air hose in the new room.
I reached up, grabbed an air hose, pulled it downward (it came down from a spring coil). I plugged the hose into a socket near my waist.
My suit inflated with a roaring sound. Cool, dry air began flowing around my body. The air was constantly being bled from exhaust ports in the suit, while the suit remained inflated. I felt the air blowing downward past my face, coming from vents inside the helmet. The airflow was designed to keep the suit under constant positive pressure, so that if the fabric developed a hole or a breach, air would flow
The high flow of air inside the suit created an almost deafening roar, which made it difficult to hear anything. The researchers had to shout to carry on a conversation in Level 4.
Jeremy closed his suit and pressurized it.
In front of us was a stainless steel door. It had a biohazard symbol on it, dark red, and the words
Martha took a hose and socketed it into her suit, pressurizing it. Then she turned and faced me. She placed herself between me and the steel door. Our suits bumped together. She pushed herself up against me until our faceplates made contact. “HOW ARE YOU DOING?” she asked. It was hard to hear her voice over the roar of the air.
“I’M FINE.”
She looked into my eyes. I thought she was examining me for any signs of claustrophobia—flushed skin, sweat standing on my face, wide staring eyes.
Evidently I looked all right. She caught Jeremy’s eye and stepped aside.
I took up my notebook and pencil, holding them awkwardly in one of my suit gloves, and we faced the steel door.
Martha looked down at my glove. “WHERE ARE YOU GOING WITH THAT NOTEBOOK?”
“IN THERE,” I shouted, indicating the door leading to Level 4.
She began laughing behind her faceplate. “IT’S FINE TO BRING YOUR NOTEBOOK INTO BL-4, BUT IT WILL NEVER COME OUT AGAIN. IT WOULD HAVE TO BE AUTOCLAVED”—cooked in a pressure oven. “THE PAPER WOULD DISSOLVE.”
So I couldn’t take notes. We would be in Level 4 for at least an hour. I wouldn’t be able to recall nearly enough. “I NEED SOME WAY OF TAKING NOTES. WHAT AM I GOING TO DO?”
“YOU COULD TRY THIS.” She handed me a sheet of flexible white plastic material, rather like paper, but, she explained, it was coated with Teflon. The researchers used this material in place of paper in a hot zone. You could write on it with a pen. It could be sterilized without damage.
“WHAT ABOUT MY PENCIL?” I asked. “CAN I TAKE THAT IN?”
“UH-UH,” Jeremy said, inspecting my mechanical pencil and shaking his head. “THAT’S GOT A SHARP TIP. PUNCTURE YOUR SUIT. SHE’LL GIVE YOU SOMETHING TO WRITE WITH WHEN WE GET TO THE HOT SIDE.”
When you moved from one room to another, you had to detach your air hose momentarily, walk without pressure in the suit, and then plug into the next air hose. As soon as the air hose was disconnected, your space suit would deflate.
Martha unclipped her air hose, and her suit went limp around her, shrinking down. She opened the steel door and stepped into the air lock and closed the door behind her. A moment later, Jeremy unclipped his air hose, and his suit went limp, and he stepped through the air lock door.
This left me alone momentarily in the staging room inside a pressurized suit. I looked back at the door we had come in through. I could do it. I could just leave. Open my space suit and climb out of it, and go back to the locker room and put my clothes on. These people wouldn’t care; they’d probably be relieved to see me go.
I unplugged my air hose. My space suit lost pressure and collapsed around me. Things got quiet: my air
