About Carbon Monoxide Detection

Carbon monoxide (CO)—also known as Carbonic oxide and Carbon(II) oxide—is used in a host of industries, for dozens of applications.

Some of the more common ones include fuel gas mixtures; chemical synthesis (organic acids, esters, alcohols, metal carbonyls); the reduction of ores; semiconductor manufacturing; and production of pharmaceuticals.

While a fairly large amount of CO is produced naturally, via photochemical reactions in the troposphere; volcanoes; and spontaneous forest fires; the most significant source affecting human health occurs from incomplete combustion of fuels. That is, insufficient oxygen is available to allow the reaction to complete to carbon dioxide.

Such incomplete combustion can occur in motor vehicles, power plants, and sundry industrial settings. Likewise, faulty heating systems and room space heaters can affect indoor occupancies, and are a hazard during cold weather.

Occupational Health/Toxicology

Exposure to carbon monoxide impedes the blood’s ability to deliver oxygen to body tissues and vital organs. When CO is inhaled, it combines with hemoglobin (in the red blood cells), producing carboxyhemoglobin (COHb), which greatly diminishes hemoglobin’s oxygen-carrying capacity.

Hemoglobin’s binding affinity for carbon monoxide is 300 times greater than its affinity for oxygen. In fact, certain pulmonary function instruments take advantage of this property, and so-called “lung diffusion” mixtures, containing 0.3% (3000 ppm) CO—along with 21% oxygen, and a neutral gas such as helium to measure the dilution factor—are supplied for this purpose.

As such, small amounts of carbon monoxide can dramatically reduce hemoglobin’s ability to transport oxygen. Common symptoms of CO exposure are headache, nausea, rapid breathing, weakness, exhaustion, dizziness, and confusion. Hypoxia (severe oxygen deficiency) due to acute carbon monoxide poisoning may result in reversible neurological effects, or it may result in long-term (and possibly delayed) irreversible neurological or cardiological effects.

High concentration CO exposures can be fatal, and still represent the leading cause of death due to poisoning in the United States. Sadly, virtually all these deaths are preventable.

What Is the Hierarchy of Controls in Workplace Safety and How Does It Protect Employees?

Employers can use the recommended hierarchy of controls to keep their employees safe from illness and injury in their facilities. Of the five strategies, elimination, substitution, and engineering controls are the most effective in controlling exposure since they do not require personnel intervention. Administrative controls and personal protective equipment are less effective in controlling risks as they require workers’ effort and are never used in isolation.

How to Create an Effective Emergency Evacuation Plan for Hazardous Gases

Many industries have one or more hazardous gases in their facilities, and they must prepare evacuation plans for hazardous gases in case of leaks or fires. Effective evacuations during emergencies depend on prior planning and training and following well-defined protocols. Both employers and employees have crucial roles before and during evacuations.

Why Industrial Gas Monitoring is Crucial for These Ten Industries

While various facilities use thousands of chemicals, some gases recur in workplaces across industries. The typical gases are carbon monoxide, carbon dioxide, ammonia, oxygen, hydrogen sulfide, chlorine, nitrogen, methane, sulfur dioxide, and chloride oxide. These gases can be flammable and/or toxic to people. The combustible gases in an oxygen-rich atmosphere can be explosive, causing risks to lives, facilities, neighborhoods, and the environment.

How Do Electrochemical Gas Sensors Work? Understanding Their Role in Industrial Safety

Electrochemical sensors react chemically with target gases and measure the current produced for quantitative estimation. The electrochemical sensors are useful for several toxic, corrosive, explosive, and environmentally polluting gases. The electrochemical sensors have become state-of-the-art technology due to their accuracy, robustness, size, and cost for industrial use.

Gas Detection in the Agriculture and Fertilizer Manufacturing Industry: Essential Safety Measures

The agriculture and fertilizer manufacturing industries utilize various gases in their processes, each playing a crucial role but also posing significant health and safety risks. This article explores the common gases used, the associated risks, the importance of gas detection technologies, and best practices for ensuring safety in these industries.
