1.1 Introduction
Laboratory safety refers to the protocols, practices, and regulations implemented to prevent accidents, injuries, and exposure to hazardous substances in laboratory environments. It encompasses a wide range of activities, including the proper use of personal protective equipment (PPE), handling and disposal of chemicals, and emergency response procedures (Smith & Jones, 2020). Laboratory safety education is a crucial component of scientific training, particularly for university students who engage in laboratory-based courses and research activities. Ensuring that students possess adequate knowledge of laboratory safety protocols is essential to prevent accidents, injuries, and potential hazards associated with laboratory work. The increasing complexity and diversity of experiments in modern laboratories necessitate a comprehensive understanding of safety measures to protect students and maintain a safe learning environment (Smith & Jones, 2020).

1.2 Background of Study
Managing laboratory safety at universities is critical due to a large number of laboratory accidents involving students that have been reported worldwide. Laboratory at university is the place where undergraduate students first develop their laboratory practices and the practice they learnt from the laboratory may carry throughout their careers. The laboratory setting can be a hazardous place to work since it mainly endow with microbial, chemical, glassware, equipment, radiation and explosion hazards. Therefore the workers are usually faced with various hazards at work. As a result the person’s health and safety may be severely threatened unless satisfactory preventive defensive measures are not taken (Zaveri & Karia, 2012).
In recent years, there has been a growing recognition of the importance of laboratory safety education at the university level. Studies have shown that proper safety training not only reduces the incidence of accidents but also fosters a culture of safety consciousness among students (Brown et al., 2018). Despite this, there remains a significant variation in the level of safety knowledge among university students, influenced by factors such as the quality of safety instruction, the availability of resources, and students' prior exposure to laboratory environments (Williams, 2019).
The significance of laboratory safety education extends beyond the immediate confines of the laboratory. It prepares students for future careers in science, engineering, and related fields, where adherence to safety protocols is paramount. Moreover, fostering a strong foundation in safety practices contributes to the overall well-being of the academic community and the integrity of scientific research (Johnson & Clark, 2017).
Historically, laboratory safety education has evolved alongside advancements in scientific research and technology. Initially, safety training in academic institutions was informal and inconsistent, often relying on the experience and discretion of individual instructors (Brown et al., 2018). However, as the complexity of laboratory work increased, so did the recognition of the need for standardized safety protocols and comprehensive safety education programs. This shift was partly driven by high-profile laboratory accidents that highlighted the potential consequences of inadequate safety practices (Williams, 2019).
In the early days of academic laboratory work, safety education was largely informal and ad hoc. It often relied on the knowledge and experience of individual instructors who passed down safety practices orally or through on-the-job training. This approach was inconsistent and varied widely across institutions and even departments within the same institution (Smith & Jones, 2020). The lack of formalized safety protocols and training led to numerous accidents, some of which had severe consequences, underscoring the need for a more structured approach to laboratory safety.
The mid-20th century marked a turning point in laboratory safety education with the recognition of the need for standardized safety procedures. High-profile accidents and the increasing complexity of scientific experiments necessitated a shift towards more formalized safety training programs. Universities began to develop and implement structured safety protocols and training sessions, often in response to regulatory requirements and professional standards set by organizations such as the Occupational Safety and Health Administration (OSHA) in the United States (Brown et al., 2018).
In response to these challenges, many universities have implemented formal laboratory safety education programs designed to provide students with a thorough understanding of safety principles and practices. These programs typically include lectures, hands-on training, and assessments to ensure students can apply safety knowledge in real-world scenarios. Despite these efforts, there remains significant variability in the effectiveness of safety education across institutions, with some programs being more rigorous and comprehensive than others (Johnson & Clark, 2017). Furthermore, the increasing diversity of student populations in universities brings additional challenges to safety education. Students come from various educational backgrounds and may have differing levels of prior exposure to laboratory environments. This diversity necessitates tailored safety education approaches that can address the unique needs and knowledge gaps of different student groups (Williams, 2019).
Recent research has also underscored the importance of fostering a safety culture within academic institutions. A strong safety culture, characterized by a collective commitment to safety and proactive risk management, can significantly enhance the effectiveness of safety education and reduce the incidence of laboratory accidents (Brown et al., 2018). This culture is cultivated through continuous education, open communication about safety concerns, and institutional support for safety initiatives.
Therefore, in Nigeria where the research was carried out, the activities that was conducted is to assess the current state of laboratory safety knowledge among university students.
1.3 Statement of Problems
Investigation revealed that students’ attitudes towards laboratory safety were lacking and needed more safety training and awareness activities or programs in the university. The association between safety knowledge and safety behavior could also be clarified by the connection of safety knowledge and safety participation. Individuals with stable emotions are considered fit to take part in safety activities, disseminate safety information, and help colleagues resolve technical safety problems (Mirza et al., 2019).
The unfortunate and regrettable state of equipment tools and laboratories have been attributed to inability of the operators to apply preventive and total maintenance culture as at when due, on the equipment tools and laboratories.
