Emergency rule for damaged biohazard suits

The Emergency rule for damaged biohazard suits is a practical protocol for preserving the boundary between a protected worker and a contaminated environment. In the Reston operation, Nancy Jaax taught the team to treat suit pressure, visible contamination, and battery life as connected safety concerns: a tear had to be taped immediately, blood had to be removed promptly, and workers had to exit for decontamination before their air supply failed.

Purpose and Operating Principle

Nancy Jaax described the suit as a pressurized enclosure. Its interior carried the worker’s normal environment into the hot area; a rip could compromise that boundary and allow contaminated air inside. The immediate response was therefore to seal a tear with tape rather than continue working with the breach unaddressed.

The precaution was grounded in the danger suspected in the monkey house. Jaax warned the soldiers that clinically ill monkeys could shed large amounts of virus, making a bite a serious exposure risk. She also emphasized awareness of where hands and bodies were in relation to the animals and their surroundings. The suit was not a reason to relax attention: it was a barrier that had to remain intact and be monitored throughout the work.

Preparation and Contamination Control

Before entering, Jaax demonstrated a way to keep repair material at hand: she wrapped extra brown sticky tape around her ankle so that a length could be torn off quickly to patch a hole. She cautioned that many unpredictable things could rip a suit. The preparation made the response immediate and local, rather than dependent on finding supplies after damage occurred.

Blood on the suit or gloves required prompt attention. Jaax instructed the workers to stop and clean blood from the suit, and to rinse their gloves at once. Bloody gloves could hide a hole, so removing visible contamination also helped preserve the ability to detect damage. The procedure joined two tasks that might otherwise seem separate: cleaning the protective surface and checking that it still protected.

Air Supply and Exit Decisions

The suits depended on batteries to run their pressurizing blowers. Those batteries lasted six hours, so workers had to leave the hot area and be decontaminated before the batteries failed. The time limit was part of the protective procedure, not merely a matter of comfort or scheduling.

During the operation, Rhonda Williams’s blower stopped and her suit began to lose its shape against her clothing. She reported that her air was going off and worried that contaminated air might be entering. Jerry Jaax initially called Gene Johnson to arrange another battery, but Williams had no spare on her belt. When a soldier nearby produced an extra battery, the team attached it and switched her over; Jerry nevertheless decided that Williams and Charlotte Godwin should leave together. The incident shows how the rule applied when the protective system faltered: restore the air supply if possible, but treat a failing suit as a reason to consider evacuation rather than assume the worker remained safe.

Role in the Reston Operation

The rule addressed a specific vulnerability in the operation: people had to work inside the monkey house while the building’s air-handling equipment was not working and the temperature was high. The team relied on pressurized suits, careful handling, communication, and timed exits to maintain protection under those conditions. Jaax’s instructions translated the abstract requirement of containment into repeatable checks and actions—carry tape, watch for blood and tears, monitor the air supply, and leave for decontamination before the system failed.

The protocol also reflects the limits of protective equipment. A suit could maintain separation only while its material and blower functioned; a tear, obscured glove, or exhausted battery could weaken that separation. The emergency rule therefore depended not on confidence in the suit alone, but on noticing changes promptly and acting before a suspected breach became an unmanaged exposure.
