Investigating Common Issues and Violations in Chemistry Laboratory Courses among Future Science Educators
Picture a bustling chemistry laboratory filled with future science educators—the very individuals who will shape the next generation of scientists. Amid the clinking of glassware and the hum of conversation, a silent crisis unfolds.
Essential safety requirements available in teaching laboratories
Critical safety practices followed in teaching laboratories
Teaching laboratory staff never received formal safety training
In this dynamic learning environment, safety protocols are often overlooked, protective equipment remains unused, and potential hazards lurk in seemingly routine procedures. This isn't merely about spilled chemicals or broken beakers; it's about a fundamental gap in how we prepare those who will teach science.
The significance of this issue extends far beyond the laboratory walls. When future educators learn in environments with compromised safety standards, they inadvertently internalize and potentially perpetuate these dangerous practices throughout their careers.
These deficiencies create ripple effects that can impact educational quality, student safety, and professional practice for decades. This article investigates the common issues and violations prevalent in chemistry laboratory courses for aspiring science educators.
Laboratory safety in educational settings extends far beyond basic protective equipment. It encompasses an integrated safety ecosystem consisting of proper facilities, consistent practices, comprehensive knowledge, and shared responsibility.
At its core, laboratory safety culture depends on individual work habits and a collective commitment to protecting oneself, colleagues, and the broader community 2 . It represents an approved set of methods and procedures for maintaining protection of property and life before incidents occur.
Adequate ventilation, appropriate laboratory sizing, proper drainage systems, reliable water flow, and availability of safety equipment.
Observation studies reveal that many teaching laboratories lack fundamental infrastructure, including safety manuals, first aid kits, and proper building systems 2 .
Correct chemical storage and handling, consistent use of personal protective equipment, proper labeling, regular decontamination, and systematic documentation.
Research shows that even when knowledge exists, consistent application remains problematic 2 .
Comprehensive training, regular safety inspections, shared safety knowledge between instructors and students, and continuous reinforcement of best practices.
Alarmingly, studies indicate that 77% of teaching laboratory staff had never received formal safety training 2 .
A revealing study conducted at the Bule Hora University Institute of Health in November 2020 provides compelling evidence about the state of safety in educational laboratories 2 .
Researchers employed an institutional-based descriptive design incorporating both quantitative and qualitative methods to assess safety requirements and practices among teaching laboratories.
The investigation focused on two randomly selected laboratories from the Health Institute, with 17 staff members participating from medical laboratory science and environmental health departments.
The results revealed significant deficits in laboratory safety infrastructure and practices. Of the safety requirements evaluated, only 33.3% were available in the laboratories studied 2 .
Observational data identified specific shortcomings: teaching laboratories lacked safety manuals and first aid guidelines, had inadequate ventilation and drainage systems, and operated in spaces with inappropriate sizing for their functions.
Perhaps more concerning were the findings on safety practices. Among the assessed safety activities:
This implementation gap highlights the disconnect between knowledge and practice that characterizes many educational laboratory settings.

Laboratories serve as crucial environments for developing scientific understanding and pedagogical skills. Since the late 19th century, science educators have recognized that laboratory instruction provides unique training in observation, supplies detailed information, and cultivates students' interest in science 3 .
These same benefits remain relevant today, particularly for future science educators who must not only understand concepts themselves but also learn how to effectively facilitate laboratory experiences for their future students.
For future science educators, learning in environments with compromised safety creates multiple detrimental effects. Beyond the immediate physical risks, students internalize poor safety norms that they may unconsciously replicate in their own teaching careers.
The absence of proper safety modeling represents a missed opportunity to develop the safety mindset essential for responsible science instruction.
Laboratory accidents occur due to various factors including mishandling of chemicals, broken glass, improper use of equipment, and misunderstanding of hazard symbols 2 . These incidents stem from inadequate safety precautions, negligence, or insufficient understanding of material safety data.
When teaching laboratories lack fundamental safety requirements and practices, they potentially contribute to health problems, environmental pollution, contamination, and chemical spills 2 .
Creating safer educational laboratories begins with addressing fundamental infrastructure deficiencies. Based on research findings, several key interventions can significantly enhance safety:
Institutions should ensure that all teaching laboratories have updated safety manuals, clearly marked first aid stations, properly functioning ventilation systems, and appropriate drainage.
Implementing systematic, documented safety inspections can identify deficiencies before they lead to incidents. The research revealed that 58.8% of teaching laboratories never underwent regular safety inspections 2 .
Dedicated funding for safety equipment maintenance and replacement ensures that protective systems remain functional when needed.
Beyond physical infrastructure, transforming safety culture requires educational interventions targeting both knowledge and attitudes:
Implementing comprehensive, required safety education for all teaching staff and students can address the finding that 77% of personnel had never received formal safety training 2 .
Laboratory instructors should explicitly communicate safety goals and success criteria to students before activities begin, providing opportunities for questions and clarification .
When safety issues arise, instructors can use guided questioning to help students develop problem-solving skills .
| Equipment/Resource | Function/Purpose |
|---|---|
| Safety manuals and first aid guidelines | Provide standardized protocols for emergency situations and routine safety procedures |
| Proper ventilation systems | Control exposure to chemical vapors and ensure adequate air quality |
| Personal protective equipment (gloves, goggles, lab coats) | Create physical barriers against chemical exposure and contamination |
| Chemical labeling systems | Ensure proper identification of substances and their associated hazards |
| Emergency safety equipment (eyewash stations, showers) | Enable immediate response to accidental exposures or contamination |
| Spill containment kits | Facilitate prompt and proper cleanup of accidental chemical releases |
| Waste segregation containers | Ensure appropriate disposal of different categories of chemical waste |

The transformation of laboratory safety culture in educator preparation programs represents both an ethical imperative and a unique opportunity.
By addressing the systemic deficiencies in current educational laboratories, we can interrupt the cycle of poor safety practices being passed to future generations of science students. The evidence clearly indicates that merely understanding safety protocols is insufficient—consistent practice, adequate resources, and ongoing reinforcement are essential components of effective safety culture.
For future science educators, comprehensive safety training and modeled best practices serve as critical preparation for their professional responsibilities. As they transition from students to teachers, their laboratory experiences will inevitably shape their instructional approaches, safety expectations, and professional priorities.
The path forward requires commitment from educational institutions, faculty, and students alike. Through coordinated efforts addressing infrastructure, education, and cultural norms, we can transform educational laboratories from settings of potential risk to showcases of safety excellence.
The findings presented in this article demonstrate the urgent need to strengthen safety culture in educational laboratories. Future science educators deserve training environments that model the safety standards we expect them to maintain throughout their professional lives.
