As industries continue to expand their use of carbon dioxide (CO2) for refrigeration, beverage dispensing, manufacturing, indoor agriculture, laboratories, and cryogenics, CO2 safety risks are increasing not decreasing.
In 2026, evolving building codes, workforce mobility and higher CO2 volumes are creating new exposure risks that businesses can no longer afford to overlook.
Below are the top five CO2 safety hazards in 2026 and how modern CO2 safety monitors help detect them before they become emergencies.
1. Undetected CO2 Accumulation in Enclosed and Confined Spaces
One of the most persistent CO2 safety hazards is gas buildup in enclosed or confined spaces, including storage rooms, walk-in coolers, mechanical rooms and valve enclosures. Because CO2 is heavier than air, it settles at low levels, making early detection difficult without properly placed sensors.
Why this risk is growing in 2026
- Increased use of CO2 refrigeration systems
- Higher-density construction
- Limited ventilation in energy-efficient buildings
How to detect it
Fixed CO2 safety monitors installed near potential leak sources and at proper mounting heights can provide continuous monitoring and audible/visual alarms when CO2 levels rise above safe thresholds. These systems also help facilities meet OSHA and fire code requirements while protecting personnel 24/7.
2. Mobile Workforce Exposure Without Personal CO2 Protection
Maintenance teams, delivery drivers, installers, and technicians often move between locations where CO2 hazards are unpredictable. Entering a space without knowing the gas concentration is one of the leading causes of CO2-related incidents.
Why this risk is growing in 2026
- More decentralized operations
- Increased third-party contractors
- Confined space entry requirements
How to detect it
Portable CO2 safety monitors worn by employees provide real-time personal protection. These devices alert users immediately if unsafe CO2 levels are present before symptoms occur. In many industries, portable monitors are now considered essential PPE.
3. Refrigeration and Cooling System Leaks
CO2 based refrigeration systems are becoming more common due to sustainability initiatives and regulatory pressure. However, higher operating pressures increase the risk of sudden leaks or system failures.
Why this risk is growing in 2026
- Expanded adoption of CO2 refrigeration
- Aging infrastructure
- Limited technician awareness of CO2-specific hazards
How to detect it
A combination of fixed CO2 detectors near compressors and piping, paired with portable gas detectors for service technicians, creates layered protection. Fixed systems can trigger ventilation or alarms, while portable units protect workers during maintenance.
4. Improperly Monitored Beverage Dispensing and Bulk CO2 Storage
Restaurants, breweries, bars and beverage facilities rely heavily on bulk CO2 storage. Leaks in these systems can quickly raise CO2 concentrations in confined areas such as keg coolers and back-of-house storage rooms.
Why this risk is growing in 2026
- Larger bulk CO2 tanks
- Centralized beverage gas systems
- Increased enforcement of fire and building codes
How to detect it
Wall-mounted CO2 safety monitors with relay outputs can activate exhaust fans, shutoff valves, or building management systems. Clear signage and alarm visibility ensure staff respond quickly during an event.
5. Compliance Gaps Due to Outdated or Inadequate CO2 Detection
Many facilities still rely on outdated detection equipment or none at all leaving them vulnerable to non-compliance with OSHA, IFC, and local fire codes. In 2026, enforcement and inspections are becoming more frequent.
Why this risk is growing in 2026
- Evolving safety standards
- Increased insurance scrutiny
- Higher liability exposure
How to detect it
Modern CO2 safety monitoring systems with data logging, calibration tracking and alarm documentation help organizations demonstrate compliance while improving overall safety culture.
How to Build a CO2 Safety Strategy for 2026
To reduce CO2 safety risks moving forward:
- Identify all CO2 sources and storage areas
- Install fixed CO2 safety monitors in high-risk zones
- Equip employees with portable CO2 detectors
- Schedule routine calibration and maintenance
- Train staff on alarm response and confined space awareness
CO2 Safety Is a 2026 Business Imperative
CO2 incidents are preventable but only with the right gas detection safety monitoring strategy. As industries grow and regulations tighten, investing in reliable CO2 gas detection is no longer optional. The organizations that prioritize safety today will protect their people, maintain compliance, and avoid costly downtime tomorrow.
