The increase in chemical laboratory establishments, coupled with advancements in experimental apparatus and technologies, has intensified the complexity of laboratory operations and heightened the risks associated with chemical experiments [3].
Despite the critical role of chemistry laboratories in advancing scientific research and innovation, the safety management systems and awareness among laboratory personnel have not kept pace with the growing complexity and scale of modern experimental practices. This disparity has led to an alarming rise in catastrophic safety incidents, underscoring the persistent risks inherent in laboratory environments. Notable incidents showed the grave consequences of inadequate safety measures in chemical laboratories [8]. In 2008, a research assistant at the University of California, Los Angeles (UCLA) tragically lost their life following a pyrophoric tert-butyllithium accident [9]. Similarly, in 2015, a hydrogen gas explosion claimed the life of a postdoctoral researcher at Tsinghua University [10], and in 2018, a high-pressure hydrogen cylinder explosion at the Indian Institute of Science in Bengaluru, India, resulted in the death of a young researcher [11]. These tragedies not only cause profound personal loss but also damage the reputations of academic institutions and hinder the progress of scientific endeavors. Such recurring events underscore the critical need for stringent safety protocols, comprehensive risk management systems, and a pervasive culture of safety consciousness within laboratories.
This review emphasizes the urgent need for robust safety strategies and actionable guidelines to address evolving risks in chemical laboratories. By analyzing current and emerging hazards, it identifies key risks and proposes targeted prevention and management strategies. These measures are vital to safeguarding laboratory personnel, protecting valuable resources, and ensuring the integrity of scientific research. By fostering a culture of safety, this review aims to promote sustainable and responsible scientific innovation while minimizing the incidence of laboratory accidents and their broader societal impacts.

2. Current and Emerging Hazards and Potential Risks

For frontline experimental personnel and laboratory administrators, the paramount task is to identify potential hazardous factors and conduct comprehensive risk assessments. This encompasses understanding the properties of various chemicals, the risks associated with the use of experimental equipment, and the unexpected incidents that may arise during experimental procedures [12,13]. Subsequently, based on the assessment outcomes, targeted management measures should be formulated and implemented, such as refining experimental operation processes, upgrading safety equipment, and enhancing safety training [14,15]. This holistic risk management strategy is crucial for mitigating risks, ensuring the safety of laboratories and personnel, and forming the foundation for maintaining the normal functioning of laboratories and the smooth progression of scientific research [16]. According to aspects such as the sources, nature, and destructiveness, the concealed hazards in chemical laboratories can be classified into the following categories (Table 1).
Chemical hazards: Chemical reagents are used and stored in all chemical laboratories. By accounting for the unique properties of different chemicals and their possible reactivity with each other, chemical hazards may be the major source of safety hazards in chemical laboratories [17]. These related hazards include flammable and pyrophoric substances [18,19,20,21]; toxic reagents [21,22,23,24,25]; corrosive substances [26,27,28]; allergens [29,30]; and psychoactive substance [31,32,33].
Physical hazards: Throughout the entire process of chemical experiment operations, certain specific equipment or instruments may be used, which could lead to some physical hazards. These hazards include high or low temperature [34,35]; high pressure or vacuum [36,37,38]; electrocution [39]; mechanical injury [40,41]; laser and radiation harm [42,43,44].
Biological hazards: Both the enduring popularity of traditional disciplines like medicinal chemistry and the surging synthetic biology in recent years have made it necessary to take biological hazards into account in chemical laboratories, such as microbes [45,46] and macromolecular allergens [47,48,49].

3. Recommended Strategies and Actions for Different Roles

The frequent occurrence of safety accidents in chemical laboratories nowadays is the consequence of multiple factors acting together [50,51,52], including the employment of hazardous reagents, non-standardized operations, unreasonable procedures, imprudent behaviors of individuals, and the absence of supervision. Achieving the objectives of laboratory safety is not a task that can be accomplished by an individual or through solitary action; it necessitates a mutual effort and communication among various roles, including experimental personnel, laboratory director, and institutional administrators. It is through this multifaceted collaboration that the likelihood of chemical laboratory safety accidents can be significantly reduced, the severity of accidents can be mitigated, and the well-being of the individuals involved and the environment are safeguarded. In the context of experimental activities, these three entities assume divergent roles and are guided by varied considerations when addressing laboratory safety. As such, they shoulder their respective responsibilities and duties within the overarching objective of safeguarding laboratory security. In the ensuing sections of this comprehensive review, we will delve into an academic dissection of the roles and responsibilities assumed by these three key constituents in the reduction in safety incidents within chemical laboratories. Furthermore, we shall delineate a comprehensive set of protocols and strategic initiatives that are imperative for all stakeholders to implement in their quest to augment the safety standards within laboratory settings (Figure 1).

Types of HazardsCharacteristics and Risks
Chemical hazardsFlammable and pyrophoric substancesThese reagents can spontaneously ignite when exposed to air or water; improper storage or use may lead to fires.
Toxic reagentsExposure to toxic substances can result in acute or chronic health hazards, potentially leading to pain, liver and kidney damage; certain special reagents may even be carcinogenic, teratogenic, have reproductive or cumulative toxicity.
Corrosive substancesContact with such substances may cause harm to the skin and mucous membranes, leading to skin corrosion, edema, or congestion.
AllergensSuch substances may cause allergic reactions in certain individuals, leading to symptoms such as itching, swelling, and subcutaneous bleeding.
Psychoactive substanceThese substances directly act upon the central nervous system, causing either stimulation or inhibition, and their continuous use can lead to dependence.
Physical hazardsHigh/low temperatureImproper use of equipment providing high or low temperatures can lead to burns or frostbite.
High pressure or vacuumHigh-pressure gas cylinders, gas steel bottles, pressure reactors, and vacuum equipment may lead to explosions.
ElectrocutionIn chemistry laboratories, if a large number of instruments and equipment are not maintained in a timely manner, it may lead to electrical shock accidents.
Laser and radiation harmSome chemistry laboratories may use laser equipment or radioactive materials, and extreme caution is required when using them.
Mechanical injuryImproper handle of heavy objects, high-speed rotating equipment, and sharp instruments can cause injury.
Biological hazardsMicrobesSome microorganisms are pathogenic or infectious. Relevant experiments must be carried out in strict accordance with the standard operating procedures (SOP) to avoid the occurrence of biosafety accidents.
Macromolecular AllergensCertain biological macromolecules may possess sensitizing effects among specific populations. Therefore, experiment operators are obliged to take proper personal protective measures.
