The Office of Personnel Management has issued guidance to employees and managers regarding their responsibilities for preparing for a terrorist attack or other emergency and the expected steps to be taken in such an event. For example, the guidance encourages employees to prepare an emergency kit to be kept at work that might contain additional dosages of any medication that an employee requires, bottled water, long-sleeved shirt or jacket, emergency contact numbers snack food, an extra pair of glasses and other items. The guidance notes: “In instances where there is a known or suspected release of biological, chemical, or radiological agents outside an agency, authorities may strongly recommend that employees shelter-in-place. That means that rather than leave their place of work, employees will stay in their office building and wait for instructions. It is unlikely that such an event would require employees to shelter-in-place for longer than a few hours.”
