Agency Forms Undergoing Paperwork Reduction Act Review

    The Centers for Disease Control and Prevention (CDC) publishes a 
list of information collection requests under review, in compliance 
with the Paperwork Reduction Act (44 U.S.C. Chapter 35). To request a 
copy of these requests, call the CDC Reports Clearance Office on (404) 
639-7090.
    The following requests have been submitted for review since the 
last publication date on January 23, 1996.

Proposed Projects

    1. Variability of Respiratory Tract Dust Deposition in Workers--
New--Adverse respiratory health effects in workers exposed to hazardous 
airborne materials can be prevented by reducing the concentration of 
the implicated agents below a threshold level. However, the actual 
``safe'' work site concentration is determined by the airborne 
particulates that are actually deposited and retained in the worker's 
respiratory tract. The proportion deposited is in turn affected by the 
volume and flow rates of the worker's breathing patterns.
    The goals of this investigation are to: (1) Develop a database of 
information related to workers' ventilatory patterns during performance 
of elemental industrial and commercial job activities, as well as 
specific dust-exposed work activities; (2) define expected variation in 
particle size dependent respiratory tract dust deposition related to 
breathing patterns representative of different job tasks; (3) 
investigate residual intersubject variability in respiratory tract dust 
deposition with explanatory variables such as height, gender, age 
smoking status, effective airway diameter, nasal geometry, and 
preexisting respiratory tract abnormalities.
    This investigation should improve the understanding of the actual 
deposition of toxic substances in the lungs and help to validate or 
modify the existing models of human aerosol deposition.

    2. Evaluation of the Efficacy of Back Belts for the Prevention of 
Low Back Injury--New--This study will provide information concerning 
the efficacy of a back supporting belt in preventing first and 
recurrent low back injuries. The research will be conducted with a 
major retail merchandise company, using selected company workers (those 
with highest lifting exposures) in selected

[[Page 21186]]

stores. NIOSH will obtain much higher quality information on the value 
of back belts in prevention of injuries in the workplace than is 
currently available, and the Institute will be able to make 
scientifically justified recommendations regarding their use of 
personal protective equipment to industry and the public.
    Workers will respond to questions concerning job history, physical 
activity, smoking history, history of injury and back pain, 
psychosocial variables in the workplace, tasks performed on the job. 
Only data necessary for the purposes of this study will be collected, 
and the questionnaires will be group administered at the workplace.
