Why don ISOL-AIDE rooms require an “airlock” or “ante room”?
Isolation rooms for mail processing are similar in many ways to hospital isolation rooms. Traffic may be frequent and staff will be pushing carts or carrying large items into the mail processing rooms. Research done in health care settings when ISOL-AIDE was first developed for TB isolation revealed that both of the ante room doors were often propped open by the staff, regardless of policy to the contrary. This practice severely compromised safety. The ISOL-AIDE patented, automatic fan speed control that compensates for pressure loss when doors are opened eliminated this problem.
