Whether or not the incidents were related, companies and worksites here that may be especially vulnerable to acts of terror should review their preparedness plans. Numerous federal departments and agencies like the Occupational Safety and Health Administration (OSHA) and the Department of Labor (DOL) have joined forces to raise the level of U.S. workplace security and safety.
The DOL and OSHA, in particular, warn of the use of explosive devices or arson as the most likely manifestation of terror attacks in corporate America. The two agencies stress the importance of fire emergency preparation, escape routes and safety equipment.
Also, OSHA points out that certain types of workplaces may be more vulnerable: those providing essential services, like subways or utilities; ones with high volumes of pedestrian traffic; buildings that offer limited emergency egress (e.g., high rises or underground complexes); "higher-profile" venues, like military installations and classified sites; or transportation hubs and facilities. OSHA advises workplaces to classify their risk levels according to "green," "yellow" or "red zones" in terms of potential hazard, to more effectively prepare against acts of terror.
