LEVELS AND GUIDELINES
NON-ENFORCED REFERENCE LEVELS
NIOSH recommendations
250-350ppm: Normal outdoor ambient concentrations
600ppm: Minimal air quality complaints
600-1000ppm: Less clearly interpreted
1000ppm: Indicates inadequate ventilation; complaints
such as headaches, fatigue, and eye/throat
irritation will be more widespread. 1000ppm
should be used as an upper limit for indoor
levels.
EPA Taiwan: 600ppm and 1000ppm
