According to this guidance, without the proper steps in place in the labor workforce, the spread of an influenza pandemic could have major consequences in the business sector and the economy. The guidance provides a plan for businesses to prepare for an influenza pandemic to help stem the pandemic and to continue business without unnecessary exposure to the influenza. The guidance divides workplaces and work operations into four risk zones, according to the likelihood of employees' occupational exposure to pandemic influenza. Recommendations for employee protection are presented for each of the four levels of anticipated risk and include engineering controls, work practices and use of personal protective equipment such as respirators and surgical masks and their relative value in protecting employees. This guidance has several websites of agencies and of information that could be helpful in finding more on pandemic influenza from both federal and state programs.
