International standards continue to upgrade, and the industry is accelerating towards a new era of industrial and commercial gas detection with high reliability and low maintenance costs
In recent years, the rapid development of industries such as global energy transformation, industrial digitization, and new energy storage, petrochemicals, semiconductors, and data centers has posed unprecedented challenges to gas safety management in industrial sites. At the same time, international investigations into major industrial accidents have continuously proven that gas leaks themselves are not the only cause of accidents. What truly determines the consequences of accidents is often whether the gas can be detected in a timely, accurate, and continuous manner.
Therefore, industrial gas detectors are gradually evolving from traditional alarm devices to important components of industrial safety management systems. Focusing on its long-term reliability, lifecycle performance, and Total Cost of Ownership (TCO), it has become a common concern for global end-users, equipment manufacturers, and standards organizations.
The Importance of Industrial Gas Detection from Accident Investigation
In recent years, multiple accident investigation reports released by the National Transportation Safety Board (NTSB), the Chemical Safety Board (CSB), and the Canadian Occupational Health and Safety Regulatory Agency (CNEST) have pointed out that the failure to detect combustible gas leaks in a timely manner, ineffective linkage of alarm systems, inadequate equipment maintenance, and lack of emergency response capabilities for hazardous gases by personnel are important reasons for the expansion of explosion and fire accidents.
These accidents cover multiple industries such as food processing, chemical manufacturing, oil and gas storage and transportation, and welding operations. Although the investigation conclusions are different, they all reflect a common fact: a reliable gas detection system is an important defense line for preventing major industrial accidents.
The modern industrial safety concept has gradually shifted from passive response after accidents to risk prevention and continuous monitoring, and highly reliable gas detection systems are important technical support for achieving intrinsic safety.
International standards continue to improve, driving the industry towards higher reliability
In order to ensure the continuous effectiveness of industrial gas detectors under real working conditions, international standards are constantly improving the product performance evaluation system.
At present, the mainstream international standards mainly include:
IEC 60079-29-1- International Performance Standard for Combustible Gas Detectors for Explosive Environments;
EN 60079-29-1- European Harmonized Standard, serving as an important technical basis for regulations such as ATEX and UKCA;
UL 60079-29-1- North American Product Performance Standard, which adds requirements for dust and water resistance declaration verification, fault verification, and software evaluation on the basis of IEC standards;
CSA 60079-29-1- Performance Certification Basis for Industrial Gas Detectors in Canada.
These standards not only specify performance requirements such as measurement accuracy, response time, environmental adaptability, long-term stability, and mechanical reliability, but also reflect the higher requirements of the international industry for long-term reliable operation.
The focus of standards has gradually shifted from "whether the product can be tested" to "whether the product can maintain reliable testing capabilities throughout its entire lifecycle".
Industry trend: The traditional "regular calibration" model is facing new challenges
For a long time, industrial fixed gas detectors have mainly relied on periodic calibration to ensure detection accuracy.
According to manufacturer recommendations, on-site risk assessments, and relevant regulatory requirements, different types of sensors typically require on-site calibration every 3 to 6 months, or even shorter cycles, to ensure that the equipment continues to meet performance requirements.
This model has effectively supported the development of industrial safety in the past decades. However, with the continuous expansion of industrial plants and the continuous production requirements, its limitations are increasingly apparent.
Firstly, maintenance costs continue to increase.
In large petrochemical plants, natural gas stations, lithium battery energy storage systems (BESS), data centers, and semiconductor factories, the number of fixed gas detectors often reaches hundreds or even thousands.
Each on-site calibration not only requires professional technicians, but also involves standard gases, calibration equipment, shutdown coordination, work permits, high-altitude operations, and maintenance record management. As the number of devices continues to increase, maintenance workload and operating costs continue to rise, and more and more companies are paying attention to the Total Cost of Ownership (TCO) of equipment, rather than just procurement costs.
Secondly, there are security risks associated with the maintenance process itself.
Many detectors are installed in hazardous areas, high-altitude platforms, confined spaces, or near continuous operation devices, and every manual maintenance means personnel entering the risk area. For oil and gas, offshore platforms, large energy storage power plants, and chemical facilities, reducing unnecessary on-site maintenance is itself an important measure to enhance intrinsic safety.
More noteworthy is that regular calibration does not necessarily mean continuous reliability.
Between two calibrations, the sensor may experience performance changes due to environmental pollution, silicon poisoning, chemical poisoning, long-term aging, or other interference factors. If only relying on fixed cycle calibration, it cannot guarantee that the equipment will always maintain the best detection state throughout the entire operating cycle.
Therefore, the industry's focus is gradually shifting from "whether calibration is completed on time" to "how to continuously ensure the reliable operation of detectors throughout their entire lifecycle".
Long term maintenance free is becoming an important direction for international industrial development
In recent years, leading international end-users, equipment manufacturers, and industry stakeholders have been actively promoting the development of industrial gas detection technology towards long-term maintenance free direction.
This trend is not simply about reducing the number of calibrations, but by improving the intrinsic reliability of sensors and the level of system intelligence, while ensuring safety and reducing maintenance requirements, achieving a dual improvement in safety and economy.
The main factors driving this trend include:
Higher security requirements. For life safety equipment, what really needs to be guaranteed is continuous and reliable operation throughout the entire service life, not just meeting performance requirements in a short period of time after calibration is completed.
Lower operating costs. Reducing on-site calibration and maintenance can significantly reduce labor, standard gas, downtime coordination, and high-risk operation costs, optimizing equipment lifecycle operating costs.
More intelligent device management. The continuous maturity of technologies such as online self diagnosis, status monitoring, predictive maintenance, and remote health management has promoted the gradual transformation of equipment management mode from "time-based maintenance" to "condition based maintenance".
At the same time, Pusheng Sensing and international leading industrial gas detector brands continue to promote the development of new generation gas sensing technology, achieving breakthroughs in key performance such as long-term stability, resistance to silicon poisoning, resistance to chemical poisoning, low drift, and adaptability to complex environments. This has laid a solid technical foundation for industrial gas detectors to achieve longer maintenance cycles and even maintenance free operation in some application scenarios.
It should be emphasized that long-term maintenance free does not mean complete maintenance free. For industrial safety equipment, necessary functional testing, system inspections, and preventive maintenance should still be carried out in accordance with the manufacturer's instructions and risk assessment requirements to ensure that the equipment always operates effectively.
The development direction of international standards is highly consistent with industry technology trends
It is worth noting that the development direction of international standards is highly coordinated with industrial technology trends.
In recent years, both IEC 60079-29-1, UL 60079-29-1, and related product certification requirements have increasingly focused on:
long-term stability
（Long-term Stability）
Environmental adaptability
（Environmental Robustness）
Anti interference and anti poisoning ability
（Immunity to Interference & Poisoning）
Fault diagnosis capability
（Fault Detection Capability）
Software and functional safety
（Functional Safety）
Full lifecycle performance consistency
（Lifecycle Performance Consistency）
The focus of standard evaluation is no longer limited to the initial performance under laboratory conditions, but rather pays more attention to the long-term reliable performance of equipment in real industrial environments.
The core of future competition: moving from "meeting standards" to "long-term reliability"
The competition in the future industrial gas detection industry will no longer be limited to detection accuracy, but will revolve around long-term reliability, total cost of ownership, and lifecycle safety management.
International leading manufacturers are actively promoting higher reliability sensing technology, smarter device diagnostic capabilities, and longer maintenance cycle product solutions, continuously reducing on-site maintenance requirements and operating costs, and providing more stable and reliable security guarantees for critical infrastructure.
In the future, technology solutions that can significantly reduce maintenance costs, minimize on-site operational risks, and maintain consistent detection performance while ensuring safety will become an important development direction for the industrial gas detection industry, and will further promote global industrial safety management to a higher level.
