Their utility is exemplified by Apollo Hospitals, which highlighted in their 2017 Excellence Report how SOPs improve efficiency and safety in healthcare delivery, a principle applicable across industries [4]. SOPs promote uniformity by standardizing operations, eliminating performance variability, and enhancing service quality. They act as safeguards against errors, particularly in high-risk tasks, by providing clear step-by-step guidelines. Additionally, SOPs are invaluable for training and skill development, serving as a reference for new and existing staff, thereby building a competent workforce. Their role in ensuring regulatory compliance and accreditation further underscores their importance, as they provide evidence of adherence to operational standards. Overall, SOPs are essential for promoting consistency, minimizing risks, supporting training, and achieving compliance, contributing significantly to organizational effectiveness and quality improvement.
2.2. Importance of SOPs in CBRN Detection
Standard Operating Procedures (SOPs) are crucial in Chemical, Biological, Radiological, and Nuclear (CBRN) detection as they establish a structured, reproducible framework for managing diverse hazards [5]. The complexity of CBRN events, involving various agents that require distinct methodologies, makes SOPs indispensable.
They provide a unified and adaptable approach, accommodating specific protocols for threats such as biological and radiological agents [6]. SOPs also standardize the operation of complex detection technologies, such as handheld detectors, ensuring consistent and accurate use while minimizing operator errors [7]. Beyond technology, SOPs enhance training and preparedness, fostering technical proficiency and consistent application of best practices.
They also play a pivotal role in interagency collaboration, enabling coordinated responses through standardized communication and shared protocols [8]. Ultimately, SOPs are foundational to effective CBRN operations, guiding technology use, training, and cross-agency coordination to address threats effectively.
2.3. Who Needs SOPs?
Standard Operating Procedures (SOPs) are crucial for selecting handheld detection devices for toxic industrial chemicals (TICs), offering a standardized approach to ensure devices meet essential standards of capability, reliability, and accuracy [9]. These guidelines address key selection criteria, including sensitivity, specificity, ease of use, maintenance needs, and durability under varying conditions, enabling consistent evaluation of devices [9].
SOPs also define testing and evaluation procedures, ensuring devices align with detection and identification standards while verifying reliability through reproducible results [9]. By mitigating risks associated with device selection errors, SOPs safeguard personnel and public safety. Additionally, they provide guidance on device care and maintenance, preserving functionality and reliability over time [9].
In conclusion, SOPs are indispensable for the standardized selection, testing, and upkeep of handheld TIC detection devices, ensuring their effectiveness and longevity.
3. Toxic Industrial Chemicals (TICs)
3.1. What Are Toxic Industrial Chemicals?
Toxic Industrial Chemicals, or TICs, constitute an array of substances produced or utilized within various industrial operations. These substances can pose serious health and environmental hazards upon exposure [10]. TICs are part of numerous industry verticals, such as chemical manufacturing, oil and gas, pharmaceuticals, and agriculture. Exposure to TICs can occur through accidental or intentional releases during their transportation, storage, or utilization, leading to potential adverse health outcomes [10].
TICs are classified into distinct categories, each determined by its specific chemical characteristics and level of toxicity. This categorization includes irritants, which cause inflammation on contact. Corrosives, which inflict chemical burns, asphyxiants, which disrupt oxygen intake, and systemic poisons, which can affect specific organs or the entire body [10].
Examples of TICs encompass substances like ammonia, chlorine, sulfur dioxide, and hydrogen cyanide. These chemicals, extensively used in a variety of industries, can cause significant harm to human health, the environment, and property upon uncontrolled release [10]. The occurrence of these chemicals in diverse physical states, such as gases, vapors, liquids, or solids, demands unique detection and response strategies for each.
The risk associated with TICs necessitates the establishment of robust detection and identification systems. Rapid identification and quantification of TICs during a release is crucial for effectively executing response strategies and mitigating harm. Handheld detection devices serve this purpose as they offer portability, ease of use, and instant results [10].
In essence, an in-depth understanding of TICs, their properties, associated risks, and the importance of swift and accurate detection are fundamental in devising appropriate emergency response and mitigation strategies.
3.2. Types of TIC
Toxic Industrial Chemicals (TICs) are widely used in industrial processes and pose significant risks to human health and the environment when accidentally released or intentionally misused. Based on classifications by OSHA [11], TICs are categorized into distinct groups based on their chemical properties and potential impacts:
1. Volatile Organic Compounds (VOCs): Highly volatile substances such as benzene and formaldehyde, commonly found in solvents and paints. Prolonged exposure can cause respiratory and neurological issues, emphasizing the need for rapid detection and control.
2. Chlorinated Solvents: Toxic chemicals like trichloroethylene and carbon tetrachloride, used in industrial processes, can harm the liver, kidneys, and central nervous system, requiring immediate detection strategies.
3. Ammonia and Ammonia Compounds: Widely used in fertilizers and plastics, ammonia exposure causes respiratory distress and reacts to form other toxic substances, necessitating robust monitoring systems.
4. Hydrogen Fluoride: Critical in producing aluminum and refrigerants, this toxic gas can cause severe burns and systemic effects, highlighting the importance of efficient detection and control.
5. Cyanide Compounds: Used in mining and metal cleaning, cyanides are highly toxic and can cause rapid, severe health effects, including respiratory distress and death, requiring urgent intervention.
6. Irritant and Corrosive Chemicals: Substances like acids and alkalis can damage the skin, eyes, and respiratory tract, making immediate first aid and medical attention vital.
7. Asphyxiating Chemicals: Gases such as carbon monoxide and hydrogen cyanide deprive oxygen, leading to unconsciousness or death, stressing the importance of rapid detection.
Despite their diverse properties, all TICs present serious risks, making robust detection, control systems, and emergency responses critical to minimizing harm and protecting public and environmental health.
3.3. Physical Properties of TICs
Toxic Industrial Chemicals (TICs) are prevalent in diverse industrial processes and carry the potential to harm human health and the environment if unintentionally or deliberately released. The physical properties of TICs, such as their volatility, solubility, and reactivity, greatly influence their behavior and associated risks, thereby playing a significant role in their detection, management, and regulation. Therefore, comprehensive understanding and characterisation of these properties are integral to formulating effective responses to TIC-related incidents.
3.3.1. Volatility
Volatility is a crucial physical property of TICs and defines a substance’s capacity to transition from a liquid or solid state into a gaseous state (vaporise or evaporate). Volatility is inversely related to boiling point; thus, chemicals with lower boiling points are more volatile [10].
A TIC’s volatility directly impacts its dispersion in the air following a release and its subsequent persistence in the environment. Highly volatile TICs, such as ammonia and chlorine, can swiftly spread over a vast region, potentially affecting a large number of individuals and systems. Conversely, TICs with low volatility, including phosgene and sulfur mustard, tend to persist in the environment for longer durations, raising prolonged exposure risks [10]. Thus, understanding a TIC’s volatility assists in predicting its behaviour post-release and informs appropriate detection and response strategies.
3.3.2. Solubility
Solubility, another pivotal physical property, denotes a TIC’s ability to dissolve in a specific solvent, typically water. The solubility of a TIC substantially affects its distribution and persistence in various environmental compartments, including air, water, and soil.
Highly soluble TICs, like hydrogen cyanide, can readily dissolve in water, possibly leading to rapid elimination from the air but causing water contamination [10]. On the other hand, TICs with low solubility, for instance, phosgene, are likely to remain airborne for extended periods, facilitating aerial detection but presenting inhalation risks. Hence, knowledge of a TIC’s solubility is fundamental in shaping targeted detection and mitigation measures.
3.3.3. Reactivity
Reactivity refers to a TIC’s propensity to undergo chemical changes or reactions when exposed to certain substances or conditions. Highly reactive TICs can generate hazardous by-products, complicating detection efforts and exacerbating risks. Table 1 explains TICs physical properties.

For instance, some TICs, when exposed to water, undergo exothermic reactions to form corrosive acids or bases, intensifying the threat they pose. Others may interact with specific chemicals, leading to the production of toxic gases or the instability of the TICs themselves, impacting their storage and handling [10]. Therefore, understanding reactivity can provide valuable insights into the potential hazards linked with specific TICs and the precautions required to safely handle and store them.
In summary, the physical properties of TICs substantially dictate their environmental behavior and detectability, underscoring their consideration in the selection of detection technologies and the development of Standard Operating Procedures (SOPs). A robust understanding of these properties enables the implementation of suitable equipment, the accurate interpretation of detection data, and the development of efficient response and mitigation strategies against TIC-related threats.
3.4. CWA vs TICs and TIMs
Distinctions among Chemical Warfare Agents (CWA), Toxic Industrial Chemicals (TICs), and Toxic Industrial Materials (TIMs)
Chemical Warfare Agents (CWAs), Toxic Industrial Chemicals (TICs), and Toxic Industrial Materials (TIMs) are distinct categories of hazardous substances, differentiated by their composition, usage, and associated risks. CWAs are specifically developed for warfare, designed to incapacitate or kill, and include nerve, blister, choking, and blood agents. These agents are highly potent, persistent, and require specialized detection and decontamination measures [12].
TICs, on the other hand, are widely used in industrial processes, such as chlorine and ammonia, and can become harmful if accidentally or intentionally released. While their toxicity varies, the health impacts of TICs can be as severe as those of CWAs depending on the chemical and exposure dose [12]. TIMs, although not inherently toxic, such as fuels or lubricants, can pose risks when released in significant quantities or under certain conditions.
The detection of these substances requires tailored technologies. Ion Mobility Spectrometry (IMS) is preferred for CWAs due to its precision in identifying gaseous compounds at trace levels. Conversely, Fourier Transform Infrared (FTIR) spectroscopy is effective for detecting TICs and TIMs by analyzing their unique infrared absorption patterns [12].
Understanding these distinctions is critical for developing appropriate detection and response strategies. It ensures proper threat characterization, the selection of effective technologies, and the implementation of robust response protocols, ultimately protecting human health and the environment from these interconnected hazards.
3.5. Hazards of TIC in Civilian Environments
Toxic Industrial Chemicals (TICs) present substantial risks to human health and the environment if accidentally released, with the severity depending on the chemical type and concentration [13]. Health impacts include acute symptoms like respiratory distress, nausea, and chemical burns, as well as severe conditions like Acute Respiratory Distress Syndrome (ARDS) caused by chemicals such as chlorine and phosgene [14]. Chronic exposure can lead to long-term health issues, including cancer, neurological disorders, and reproductive problems.
Environmental hazards include soil and water contamination, with Persistent Organic Pollutants (POPs) like PCBs and dioxins accumulating in food chains and causing enduring risks to ecosystems and human health [13]. The behavior of TICs, influenced by their volatility, reactivity, and solubility, determines their spread and persistence. Volatile TICs can quickly contaminate large areas, while less volatile ones may result in prolonged contamination. Reactive TICs may form secondary hazardous compounds, complicating mitigation efforts.
Understanding the health and environmental hazards of TICs, alongside robust detection, response, and prevention strategies, is critical to reducing their impact and safeguarding civilian environments.
4. Detection Equipment
4.1. What Is Detection?
In the realm of chemical, biological, radiological, nuclear, and explosive (CBRNe) threats, including toxic industrial chemicals (TICs), understanding detection is imperative for strategic response and risk mitigation. According to the National Academies Press 1, detection entails identifying the presence of potentially harmful substances by interpreting their unique signatures, which can be physical, chemical, or even radiological [15].
Detection technologies and methodologies are a cornerstone of any comprehensive strategy to prevent or respond to CBRNe events. They serve as our first line of defense against these threats, providing critical information that informs decision-making processes about containment, mitigation, and decontamination strategies. Without effective detection, it is impossible to know when and where a CBRNe event has occurred, what agents are involved, or how to appropriately respond [15].
While there are numerous detection technologies available, each has its strengths, weaknesses, and areas of applicability depending on the nature of the threats. Some detection methods can quickly identify the presence of a wide range of agents but may lack the specificity to differentiate between them. Conversely, other technologies offer high specificity but may not be as broad in their detection capabilities.
For instance, optical detection systems, such as Raman spectroscopy and laser-induced breakdown spectroscopy, are highly sensitive and can provide almost instant results. They can identify and differentiate among a vast array of chemical substances, including TICs, making them valuable for CBRNe responses. However, these systems are typically limited to detecting chemical threats and may not be as effective in identifying biological, radiological, or nuclear threats.
Similarly, biological detection systems, such as immunoassays and polymerase chain reaction (PCR) techniques, are highly specific in identifying biological agents. Yet, their application is limited to biological threats, and they require significant time to deliver results, which might not be feasible in emergency scenarios.
Radiation detection devices, on the other hand, are designed to identify and measure radiological and nuclear threats. These systems often rely on technologies like ionization chambers, scintillation detectors, and semiconductor detectors. They are capable of determining the type and intensity of radiation but are limited to detecting radiological and nuclear threats.
Detection also extends to the recognition of explosive threats. Technologies like ion mobility spectrometry and X-ray diffraction are commonly used for this purpose, offering rapid detection and identification of various explosives.
While each of these technologies is highly valuable in specific contexts, none alone provides a comprehensive solution to all CBRNe threats. This necessitates a multifaceted approach to detection, employing a variety of technologies to cover the broad spectrum of potential threats.
Moreover, detection does not occur in a vacuum. It is a part of a broader system that includes information gathering, threat analysis, decision-making, and response implementation. Effective detection systems must, therefore, be designed with integration in mind. They need to be compatible with other technologies, able to communicate critical information to decision-makers quickly, and robust enough to operate under challenging conditions [15].
In conclusion, detection plays a vital role in preventing and mitigating CBRNe threats. By leveraging a range of technologies and maintaining a systems-wide perspective, we can improve our detection capabilities and enhance our readiness to respond to these critical threats.
4.2. Detection vs Identification
Understanding the differences between detection and identification technologies is crucial when dealing with chemical, biological, radiological, nuclear, and explosive (CBRNe) threats, including toxic industrial chemicals (TICs). According to [16] and [15], these terms denote different stages of threat recognition and response, each carrying its own set of challenges and technological solutions.
Detection, as mentioned earlier, is the first line of defense against CBRNe threats. It is the act of sensing the presence of potentially harmful agents by using devices sensitive to their signatures. Detection technologies serve to alert us to the existence of a threat, often by monitoring changes in the environment that indicate the presence of potentially harmful substances. They can often sense a wide range of agents but typically lack the ability to differentiate among them. This initial process is crucial for early warning, enabling emergency services to respond as swiftly as possible.
Detection technologies in the CBRNe context can range from chemical detectors like ion mobility spectrometers and flame photometers, biological detectors like immunoassays and PCR techniques, to radiological and nuclear detectors like Geiger-Muller counters and scintillators, and even explosive detectors using technologies like X-ray diffraction.
However, while detection is critical for initial response, it is often not enough for a comprehensive understanding of the threat and determining an effective mitigation strategy. That’s where identification comes in.
Identification refers to the process of determining precisely which agent or agents are present. Unlike detection, which merely signals the presence of a threat, identification allows us to discern the nature of that threat, offering information about the specific agent or agents involved. This stage is critical for making informed decisions about the necessary protective measures, the appropriate treatment for those exposed, and the most effective decontamination strategies.
Identification technologies are usually more sophisticated and complex than detection technologies, often requiring more time and resources to operate. They aim to deliver a high level of specificity, which means they need to differentiate among a wide variety of potential threats. In the CBRNe context, identification technologies can include mass spectrometry for chemical threats, DNA sequencing for biological threats, gamma spectroscopy for radiological and nuclear threats, and advanced imaging technologies for explosive threats.
It is worth noting that there is often a trade-off between detection and identification in terms of speed, specificity, and breadth of application. Detection technologies are typically faster and capable of sensing a wider range of threats, but they often lack specificity. Conversely, identification technologies offer high specificity but may be slower and less comprehensive in their applicability.
In summary, both detection and identification are vital components of any comprehensive CBRNe response strategy. By employing a variety of technologies for detection and identification and understanding the strengths and limitations of each, we can better prepare for, respond to, and mitigate the effects of CBRNe events.
4.3. Handheld Detection vs Fixed Detection
Chemical, Biological, Radiological, and Nuclear (CBRN) defense operations must choose between two primary types of detection systems: handheld and fixed. Handheld detection systems are portable devices operated by individual responders, while fixed detection systems are permanently installed at specific sites, delivering continuous monitoring [17].
4.3.1. Advantages and Disadvantages of Handheld Detection Systems
Handheld detection systems offer numerous benefits, most notably their high portability. They can be easily transported to various locations, enabling their use in diverse scenarios, especially where rapid deployment is crucial. Additionally, compared to fixed systems, they are generally more economical as they circumvent the high infrastructure and installation costs [17].
Nonetheless, handheld detection systems possess certain limitations. They may lack the sensitivity of fixed systems and might struggle to detect certain types of hazardous materials or lower concentrations of these substances. Moreover, these portable systems generally necessitate more frequent calibration and maintenance, which can be resource-intensive and time-consuming [17].
4.3.2. Advantages and Disadvantages of Fixed Detection Systems
On the other hand, fixed detection systems boast several advantages over handheld systems. They typically offer greater sensitivity, detecting lower concentrations of hazardous materials. Given their stationary nature, they require less frequent calibration and maintenance [17].
However, fixed detection systems are not without drawbacks. They are usually more expensive than handheld systems, given their requirements for significant infrastructure and installation. Their lack of portability may render them less suitable for scenarios where mobility and immediate deployment are key [17].
4.3.3. Making the Choice
The choice between handheld and fixed detection systems depends on the specific demands of the CBRN defense operation. Considerations such as operational environment, the nature of the threat, budget constraints, and time requirements can inform the decision. Handheld devices may be better suited to operations demanding real-time detection and high mobility, while fixed systems might be preferred for consistent monitoring of specific sites and detection of low-concentration threats.
Decisions on the most appropriate detection system significantly impact the capacity to identify and respond to threats effectively. Thus, understanding the strengths, weaknesses, and appropriate applications of both handheld and fixed detection systems is critical.
4.4. Detection Technologies (Pros and Cons)
Toxic Industrial Chemicals (TICs), due to their widespread use and inherent hazardous properties, pose a significant risk to public health and safety. The ability to swiftly and accurately detect these substances is crucial in mitigating potential hazards, making detection technologies an essential aspect of handling TICs. However, no single detection technology can fully encompass all the requirements for handling diverse TICs. Herein, we analyze the advantages and disadvantages of several common detection technologies, primarily guided by two primary sources: [15] and [16].
Please note, while these technologies have a wide range of applications, choosing the right one depends on the specific needs of the task or situation. Therefore, an understanding of the advantages and limitations of each technology is crucial. Find below Table 2: shown comparison chart for various handheld detection technologies (pros & cons).

4.5. Handheld Detection Equipment in the Market
The application of handheld detection technologies for toxic industrial chemicals (TICs) is a critical component in situations demanding rapid and efficient identification of hazardous substances. These mobile instruments, because of their portability, user-friendliness, and swift reaction, serve as valuable tools for on-field personnel in potentially hazardous environments. This section provides an overview of several popular handheld detection tools available in the market, focusing on their operational mechanisms, strengths, and drawbacks.
4.5.1. Photoionization Detectors (PID)
Photoionization Detectors (PIDs) have found a crucial role in numerous industries due to their unique ability to identify and measure volatile organic compounds (VOCs), including but not limited to benzene, toluene, and xylene. They operate by ionizing the target sample using high-energy ultraviolet light, which generates an electrical charge. The concentration of VOCs can then be derived from the ionization current [18]. See Figure 1 Photoionization Detector (PID).
Given their impressive sensitivity to low VOC concentrations, PIDs have been widely adopted in industries such as petrochemicals, waste processing, and manufacturing where VOCs are common. For instance, in the petrochemical industry, VOCs like benzene, toluene, and xylene are frequently encountered. These compounds pose both health and environmental risks. PIDs provide real-time monitoring, thus enabling quick response to any potential leaks, spills, or exposure, subsequently ensuring workplace safety and reducing environmental hazards.
In the environmental sector, PIDs are employed to monitor air quality and detect the presence of harmful VOCs. They offer a way to quickly and accurately detect any dangerous changes in VOC levels, making them essential tools for environmental monitoring and safety regulation enforcement [19].
Moreover, PIDs are also used in the emergency response sector. Incidents involving chemical spills or leaks often require the immediate identification of the substances involved to safeguard first responders and determine the appropriate mitigation strategies. With their ability to quickly detect and measure VOCs, PIDs provide crucial information that can guide effective incident response [18].
Figure 1. Photoionization detector (PID) (Source: [20]).
However, despite their considerable benefits, PIDs do come with limitations. Their effectiveness can decrease in environments with high VOC concentrations, high humidity, or low temperatures due to potential saturation. Therefore, understanding these constraints and working to address them is necessary to ensure optimal performance and accurate readings.
In conclusion, PIDs have emerged as vital tools for detecting and measuring VOCs in various industrial, environmental, and emergency contexts. While they do have certain limitations, their benefits substantially outweigh these, particularly in terms of enabling rapid and effective response to potential hazards [18] [19].
4.5.2. Fourier-Transform Infrared Spectroscopy (FTIR)
Fourier-Transform Infrared Spectroscopy (FTIR) is an analytical technique that utilizes the infrared region of the electromagnetic spectrum to identify and quantify gases and vapours, based on their distinct infrared spectra. Check Figure 2 Principle of operation of FTIR (Fourier transform infrared) spectroscopy. This high-resolution and highly accurate technique is primarily used in analytical chemistry for the identification and quantification of a plethora of Toxic Industrial Chemicals (TICs), making it a powerful tool in various industrial sectors and for environmental monitoring [21].
Figure 2. Principle of operation of FTIR (Fourier transform infrared) spectroscopy (Source: [21]).
For example, FTIR has been instrumental in the automotive industry. The emission of exhaust gases from vehicles, particularly those using internal combustion engines, is a significant contributor to environmental pollution. TICs such as carbon monoxide, nitrogen oxides, and unburned hydrocarbons are some of the key pollutants from vehicle exhaust that are of concern. FTIR devices provide real-time detection and quantification of these TICs, contributing significantly to studies on vehicle emissions and the development of cleaner and more efficient engine technologies [21].
Further, in the petrochemical industry, FTIR can detect and quantify gases like benzene, toluene, and xylene that are commonly present. These compounds pose potential health risks to workers and could have significant environmental impacts if not adequately managed. FTIR offers a solution for real-time monitoring, enabling quick responses to any leaks or spills, thus ensuring the safety of the workplace and reducing environmental hazards.
Similarly, FTIR has found utility in the field of hazardous material response. Emergencies involving chemical spills or leaks often require immediate and accurate identification of the substances involved to protect first responders and determine the appropriate mitigation strategies. FTIR detectors can identify a broad range of TICs quickly and accurately, even in complex mixtures, providing crucial data for the efficient management of hazardous material incidents.
However, it’s important to note that while FTIR devices are extremely versatile and accurate, their high cost and the requirement of specialized training for their operation limit their widespread usage. Therefore, strategies to decrease the cost and simplify the operation of these detectors could lead to a broader implementation of this critical technology across multiple industries.
In conclusion, FTIR is a powerful tool for the detection and quantification of TICs across various industries, from automotive and petrochemical to emergency response and environmental monitoring. Despite the limitations regarding cost and operational complexity, its potential to significantly improve the management of TICs in these fields is undeniable [21].
4.5.3. Surface-Enhanced Raman Scattering (SERS)
Surface-Enhanced Raman Scattering (SERS) detectors are key devices in the arsenal of detection equipment, with their unique functionality of amplifying Raman scattering signals from samples via metallic nanoparticles.
