UNIVERSITY OF ARIZONA
DEPARTMENT OF RISK MANAGEMENT
HANTAVIRUS AWARENESS TRAINING
SELF -STUDY (Feb 2006
All U of A employees, volunteers and students who wear respirators must be enrolled in the UA Respiratory Protection Program. (http://fp.arizona.edu/riskmgmt/respiratory_protection.htm)
This self study quiz is a prerequisite for OSHA mandated respirator medical clearance, training and fit testing. Please visit the URLs listed for each question, and answer the questions below before scheduling the hands-on respiratory protection class.
Step 1: Fill out self study quiz below, and submit via email to firstname.lastname@example.org or fax to (520) 621-3706
Step 2: Contact Julia Rosen at Risk Management to obtain an OSHA respirator medical questionnaire. (Julia Rosen, 621-1570), email@example.com.
Complete questionnaire and submit to Occupational Health Services: http//www.health.arizona.edu/webfiles/health_services_occupational_health.htm
Some individuals may need to have a physical exam, based on questionnaire answers.
Step 3: Schedule a respiratory protection class with Risk Management Julia Rosen 621-1570. Allow 1 1/2 - 2 hours. Each student will be given a “prescription” for a respirator, including the brand and size respirator that fits. Just like shoes, respirators come in different sizes for different faces. Men need to be clean shaven where the respirator could contact skin. Not even a day’s worth of stubble is allowed. As an alternative, hooded powered air purifying respirators (PAPRs) may be used. These are much more costly (hundreds of dollars), but do not require medical certification or fit testing for users, and are the only type of respirator that will protect bearded individuals.
Step 4: Purchase respirators and other PPE (personal protective equipment) required for the job. Costs are your department's responsibility.

Human case exposures/transmission of Sin Nombre virus in AZ has been linked to
P. manc. and P. eremicus. P. boylii in northern AZ has been shown to carry another Hantavirus - Limestone Canyon virus - but nothing is known about its pathogenicity to humans. There are also 3 other types of rodents that have shown to carry hantavirus. Which of these are found in Arizona? http://www.cdc.gov/ncidod/diseases/hanta/hps/noframes/rodents.htm
