sample gases. Over the life of the analyzer, the concentration of particulate matter will become
enriched within the gas handling components. When performing repairs and maintenance on
the analyzer:

• Avoid direct skin contact with used gas handling components.
• Do not smoke, drink, or eat in the work area.
• Wear goggles or eye shields.
• Wear a suitable face mask to protect against inhalation of particulate matter.
• Do not wet fingers, eyes, or any exposed skin.
• Pack used gas handling components for disposal in sealed packaging and label them
Contaminated .
• Dispose of contaminated items as hazardous material according to the applicable local,
national, or international health and safety regulations and pollution regulations.
