CARBON MONOXIDE

Page 3: Carbon Monoxide Monitoring Presented by: Interscan Corporation.

CARBON MONOXIDE IS THE MOST COMMON TOXIC GAS

As a product of combustion, it is ubiquitous

CO is one of the few toxic gases that can be encounteredat home or on the job

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 upwhen 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

Page 7: Carbon Monoxide Monitoring Presented by: Interscan Corporation.

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.

Page 8: Carbon Monoxide Monitoring Presented by: Interscan Corporation.

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

Page 9: Carbon Monoxide Monitoring Presented by: Interscan Corporation.

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)

Page 10: Carbon Monoxide Monitoring Presented by: Interscan Corporation.

NIOSH IDLH [Immediately Dangerous to Life and Health]

(as of Feb, 2011)

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!!

1200 ppm

Page 11: Carbon Monoxide Monitoring Presented by: Interscan Corporation.

GRADE “D” BREATHING AIR Per ANSI / CGA G-7.1.1989

As it pertains to carbon monoxide…

No more than 10 ppm

Applications Engineering

Page 13: Carbon Monoxide Monitoring Presented by: Interscan Corporation.

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?
