OSHA - NIOSH Worker Info: Protect Yourself-Spirometry Breathing Test
DHHS (NIOSH) Publication Number 2011-132
Inhalation of some dusts, gases, or other air contaminants in your workplace as well as some personal exposures, such as cigarette smoking, can harm your lungs. Spirometry testing (a type of pulmonary or lung function test) may identify breathing problems early, which may prevent more serious problems. Spirometry testing is required for some workers by OSHA standards (see Screening and Surveillance: A Guide to OSHA Standards at: www.osha.gov/Publications/ osha3162.pdfpdf iconexternal icon).
