In industrial environments, safety is more than a priority—it's a responsibility. Yet, one of the most dangerous threats to worker health is often invisible, odorless, and too often overlooked: Carbon Monoxide (CO).

What Is Carbon Monoxide and Why Is It Dangerous? 

Carbon monoxide is produced by the incomplete combustion of carbon-based fuels—common in many industrial operations involving furnaces, generators, vehicles, welding, or combustion-powered tools. 

The real danger lies in how CO replaces oxygen in the bloodstream, reducing the body’s ability to deliver oxygen to vital organs. Even low levels of exposure over time can cause serious health issues, while high levels can be fatal in minutes. 

Carbon Monoxide

Why CO Is a Hidden Threat in Industry 

Industrial environments are particularly vulnerable due to: 

  • Confined or poorly ventilated spaces 
  • Internal combustion engines operating indoors (e.g., forklifts)
  • Malfunctioning equipment or heating systems
  • Temporary generators during power outages 

Symptoms to Watch For on the Job 

CO poisoning often mimics common ailments, leading to delayed responses. Symptoms may include: 

  • Dizziness or light-headedness 
  • Headache
  • Fatigue or confusion
  • Shortness of breath
  • Loss of consciousness 

Workers may mistake these symptoms for dehydration, overexertion, or even stress—delaying critical intervention. 

Prevention: A Workplace Imperative 

Mitigating carbon monoxide risk in industrial settings isn’t just about compliance—it’s about culture. Here’s what responsible leaders and EHS professionals should ensure: 

  • ✅ Install CO Monitors: Fixed and portable detectors should be strategically placed, especially in enclosed spaces or near combustion equipment. Choose industrial-grade units with real-time monitoring and alerts. 
  • ✅ Routine Equipment Maintenance: Schedule regular inspections for all fuel-burning equipment. Faulty engines and ventilation systems are common CO sources. 
  • ✅ Train Your Team: All staff—from floor workers to supervisors—should be trained to recognize CO symptoms, understand evacuation procedures, and respond to alarms. 
  • ✅ Ventilate Properly: Ensure effective exhaust systems and never allow combustion engines to operate in enclosed areas without ventilation. 
  • ✅ Emergency Response Plan: Develop a clear, practiced protocol for CO alarm events, including evacuation, first aid, and communication with emergency services. 

Final Thought: Culture Drives Compliance 

While regulations mandate CO safety protocols, true protection comes from fostering a safety-first culture. Leaders who prioritize preventive maintenance, ongoing training, and open safety communication build workplaces where hazards like CO are actively managed—not ignored. 

Carbon monoxide doesn’t announce itself. But with the right systems in place, your team will always be prepared. 

Let’s lead by example. Workplace safety isn’t a checkbox—it’s a commitment.

Video Smoke Detection for Waste Recycling

Video Smoke Detection is perfect for a fast response to fires in high roofed buildings and harsh operating conditions.

Real Fire - Smoke Detection in MSW Storage

Watch Smokecatcher detect smoke in an MSW storage building. The smoke is coming through from a fire in the adjoining storage area.

Real Fire - SRF Storage Area

Watch Smokecatcher detect a fire in an SRF Storage bunker. Sadly, the alarm wasn’t responded to and the site lost a 4hr window of opportunity between smoke detection and flames appearing.

Video Smoke Detection for Logistics

Video Smoke Detection overcomes the risks of stratification and other challenges for early fire detection in logistics and storage facilities.

EFW Bunker Fire

Watch Fire Rover detect and suppress a fire in the waste bunker at an EFW facility!

Tipping Hall Fire

See how the Fire Rover detects and suppresses this fire at a clients tipping hall. Note how the smok is spreading out at low leve, rather than rising. This is called ‘stratification’ and is one of the many reasons why roof-mounted smoke detection systems like beam detectors and HSSD is not suitable for many recycling applications.

Battery Storage Fire

Watch the Fire Rover detect and suppress a fire at a battery storage facility. This targeted and intellegent control makes the Fire Rover particularly well suited to high hazard storage applications.

Explosive Lithium-ion Batter Fire

Watch the Fire Rover tackle a battery fire in a tipping hall. Note how the exploding battery cells start three separate fires, which the operator individually suppresses (whilst avoiding the site operators in the vicinity).
