CO (CO)
Carbon Monoxide
Silent, odorless, and highly poisonous asphyxiant resulting from incomplete fuel combustion.
What is CO (Carbon Monoxide)?
Carbon Monoxide (CO) is a silent, odorless, colorless gas. When inhaled, it binds to hemoglobin with 200 times higher affinity than oxygen, forming carboxyhemoglobin and depriving critical organs and brain tissue of vital oxygenation.
- •Faulty furnace flues, cracked heat exchangers, and blocked chimneys
- •Idling vehicles in enclosed parking garages and loading docks
- •Dense urban vehicle congestion and engine idling zones
Health Effects of CO
- •Headaches, dizziness, confusion, nausea, and disorientation
- •Loss of consciousness and fatal asphyxiation at high concentrations
- •Neurological impairment, memory deficit, and chronic cardiovascular stress
Concentration Levels & Safety Guidelines
Standardized thresholds to identify when active ventilation and air filtration intervention is required.
Safe ambient background in well-ventilated spaces.
Occupational limit threshold; inspect combustion sources immediately.
Critical safety hazard; emergency ventilation and evacuation mandatory.
| Organization | Guideline Limit | Exposure Timeframe |
|---|---|---|
| World Health Organization (WHO) | 4 mg/m³ (3.5 ppm) | 24-Hour Mean |
| OSHA | 50 ppm | 8-Hour Workplace Limit |
How DLE Measures CO
CO is oxidized to CO₂ at the anode, yielding electrons counted with sub-ppm precision.
Safety-critical CO monitoring for garages, boiler rooms, and commercial kitchens.
