CARBON MONOXIDE
SYNONYMS
•Coal gas
•Carbon oxide
•Carbonic oxide
•Exhaust gas
•Flue gas
•Monoxide
CARBON MONOXIDE IS THE MOST
COMMON TOXIC GAS
CO is one of the few toxic gases that can be encountered
at home or on the job
As a product of combustion, it is ubiquitous
Colorless and odorless, CO is a silent killer
CO HEALTH EFFECTS
At 200-300 ppm, can cause fatigue in healthy individuals,
and chest pain in those with heart disease.
At higher concentrations, can cause impaired vision and
coordination; headaches; dizziness; confusion; nausea.
Can cause flu-like symptoms (ca. 250 ppm) that clear up
when in clean air.
At 2000 ppm, can be rapidly fatal
TOXICOLOGY
Carbon monoxide is an asphyxiant
Inhalation of CO causes tissue hypoxia by preventing
the blood from carrying sufficient oxygen
Carbon monoxide combines reversibly with
hemoglobin to form carboxyhemoglobin
The reduction in oxygen-carrying capacity of the
blood is proportional to the amount of
carboxyhemoglobin formed
Occupational
Exposure
Standards
OSHA Standards (as of Feb, 2011)
The OSHA PEL ( Permissible Exposure Limit, based on an
8-hour time-weighted average) is 50 ppm
Special provision for maritime workers/longshoring
[29 CFR 1918.94(a)(1)(i))]
…employees shall be removed from the enclosed space if the
CO concentration exceeds a ceiling of 100 ppm.
Exception: The ceiling shall be 200 ppm instead of 100 ppm
for Ro-Ro operations.
ACGIH TLV® [Threshold Limit Value]
(as of Feb, 2011)
TLV-TWA (based on an 8-hour time-weighted average)
is 25 ppm
Biological Exposure Index (BEI®) is recommended for carbon
monoxide ─
Based on percent carboxyhemoglobin saturation in blood, or
end-expired CO concentration in alveolar air
NIOSH REL [Recommended Exposure Limits]
(as of Feb, 2011)
TLV-TWA (based on an 8-hour time-weighted average)
is 35 ppm
Ceiling value of 200 ppm
(should not be exceeded at any time)
NIOSH IDLH [Immediately Dangerous to Life and Health]
(as of Feb, 2011)
1200 ppm
IDLH: The airborne concentration from which a worker
could escape without injury or irreversible health effects, in
the event of the failure of respiratory protection equipment.
IDLH values are based on effects that might occur as a
consequence of a 30-minute exposure.
Regardless of the 30-minute basis, if equipment failure occurs,
LEAVE THE AREA AT ONCE!!
GRADE “D” BREATHING AIR
Per ANSI / CGA G-7.1.1989
As it pertains to carbon monoxide…
No more than 10 ppm
Applications
Engineering
AT A MINIMUM, CONSIDER
Portable/survey or fixed continuous monitoring requirement?
Interfering gases present?
Will unit be used/installed in electrically hazardous area?
Is data logging needed?
