ABSTRACT
The focus of this study is to investigate the extent of safety compliance, in secondary school science laboratories
in Abakaliki Education Zone of Ebonyi State. Two research questions and one hypothesis guided the study. The
study employed descriptive survey design. This is to enable the researcher describe the extent of safety
compliance and make decisions based on empirical evidence. The researcher used a total number of seventy-two
(72) public secondary schools, out of 78 public secondary schools in the zone. This is because, six secondary
schools out of 78 public secondary schools in the zone do not have science laboratory at the time of this research
data collection. The researcher did not sample since, the number of secondary schools in the zone was not high.
A four-point scale structured questionnaire developed by the researcher was used to collect data on the safety
compliance. The instrument is made up of fourteen (22) items. Mean and standard deviation were used in
answering the research questions while, Analysis of variance (ANOVA) was used to test the hypothesis at 0.05
level of significance. The results revealed that the extent of safety compliance in secondary school science
laboratories in Abakaliki Education Zone of Ebonyi State was high. Based on the findings of the study, the
researcher therefore, recommended that Government of Ebonyi State and school authorities should keep up the
present level of laboratory safety compliance in secondary school science laboratories in the state by
collaborating with curriculum developers to review the existing curriculum and integrate the basic tenets of
laboratory safety measures in the curriculum.
Keywords: safety, safety compliance, science and science laboratory.
INTRODUCTION
Science makes life easy and improves the standard of living. For science to strive well, it requires well equipped
and standard laboratories. The study of nature and natural phenomena is referred to as science. Mbajiorgu (2021)
stated that the study of nature and natural phenomena deals with experimental approach of physical measurable
and observable quantities. Science is a vital tool to every developing country or nation as supported by Nwana,
Bajah and Obioha (2021); that professions such as agriculture, dentistry, engineering, geology, medicine,
astronomy, space, exploration and pharmacy would be difficult to develop without science education. Science
education subjects include physics, biology and chemistry. Instruction that is student-centered and emphasizes
the role of laboratory demonstrations and experiments is the best method to ensure students develop the essential
skills of science (Mbajiorgu, 2021).
Allen, Henry, Albert and Donald (2021) described laboratory as a building or room fitted up for conducting
scientific experiments, analysis or similar works. Laboratory is thus a workshop for scientists. Igwe (2023) stated
that, science laboratory is a facility for learning what science is and its application by scientists. It can be in-door
like well-designed and equipped rooms found in most secondary schools or out-door involving places such as
riverside, work shop, field and even market. This means that laboratory experience could be attained either in-
door or out-door, which implies providing opportunity for students to develop the understanding of practical and
theoretical concepts through solving problems by participation in series of experimental, observational and
demonstrating activities. Therefore, science laboratory is a special facility for teaching science through research
evidence in secondary school science in general (Igwe, 2023). The laboratory serves as the basic practical

framework for carrying out laboratory activities (that is, the study of science concepts, using the scientific
method of problem definition, theorizing, testing and so on).
Nwanuma (2021) opined that laboratory activities are expected to enable students obtain the scientific methods
of doing science as well as to help them develop more favorable attitudes. Nwanuma (2021), further states that
such science laboratories should be relatively safe for those using it as well as the materials, chemical and tools
which are stored and used in the science laboratories. Thus, a laboratory is safe if it does not in any way constitute
hazard to health, life and property while being used for teaching and learning.
The use of laboratory requires extreme carefulness in order not be involved in accident or hazard. Ibam, Ibrahim
and Idoko (2021) stated that the use of laboratories is liable to hazards due to the presence of chemicals and
dangerous equipment not properly handled by laboratory users. Laboratory hazards and risks are many and
varied as reported by Nkwegu (2023) and include exposition to poison, burns, infection, explosion and stains.
Other causes of laboratory accidents he outlined include the following; distraction, poor storage of materials and
equipment, failure to use protective items for safety, the use of worn-out equipment. Adigun (2022) reported
that laboratory accidents are in some cases inevitable; they may in most other cases be minimized or completely
avoided if adequate emphasis is placed on correct laboratory safety measures.
Working with safety ensures achieving purpose without damage of any kind, injury or accident. Ali (2023)
stressed that safety implies that students, teachers and other laboratory users are not injured or killed, stating that
materials and equipment in the laboratory are not damaged during use. Allen, Henry, Albert and Donald (2021)
posited that safety refers to the state of being protected from or unlikely to cause danger, risk or injury. Okorie
(2023), opined that appropriate safety measures to prevent hazards while making use of the laboratory should be
uppermost in priority. Stating that, laboratory users who are not conscious of safety in the laboratory may expose
themselves to dangers, hazards or accidents. For laboratories to be safe, it must have safety measures put in place
and enforced. Ikoku, Ahmed and Joju (2023) observed that lack of qualified and dedicated teachers and lack of
safety facilities such as fire extinguishers, protective eye glass or goggle, safety shoes, fume cupboards among
others threaten the safety of those who use the laboratory. Igwe (2023) reported that cases of accidents in
Nigerian secondary schools are inevitable during laboratory activities.
To prevent continuous exposure of laboratory users to laboratory hazards, Hayble (2021), opined that laboratory
safety measures must be utmost in priority. The teacher should take note of possible accidents which could occur
in a given situation and appropriate action to be taken to avoid any unfortunate event, when planning practical
for science laboratory work. Hayble (2021), maintained that most reagents and dangerous instruments should
have hazard signs placed on them and the safety measures or precautions of usage clearly enumerated in the
manual to assist the user.
Despite the various sources of hazards in the laboratory, Duru (2023) believed that working in the laboratory is
a very safe place to work. He opined that, making use of laboratory safety wears like gloves, safety glasses and
laboratory coat could prevent contamination of the body with chemicals. Science teachers have the responsibility
to develop safety conscious attitude in the students by creating awareness of the hazards involved in any
laboratory as well as the rules and procedures guiding a particular activity. Nadino (2022), posited that science
teachers must be knowledgeable on the required safety measures needed in each laboratory activity, know
procedures and potential hazard associated with the use of laboratory materials. Also, Ibam, Ibrahim and Idoko
(2021), advised that science students and teachers should acquire the skills for safety measures in the laboratory.
Such skills include the skill of proper storage of chemicals, skill on the use of various safety instruments, skill
in the disposal of laboratory wastes, skill in the management of emergency situations, personal practices in the
laboratory. Ibam, Ibrahim and Idoko (2021), also pointed out that every laboratory should have safety
instruments.
Safety is the state of being protected from harm or danger. Safety can also refer to the control of known hazard
in order to minimize the rate of risk. Flinn (2022) is of the view that laboratory safety deals with the development
of skills and responsibility involving every laboratory user which must be integrated into science laboratory
curriculum. This implies that safety measures must be integral part of each laboratory course including research
with increasingly broader scope at more advanced levels.

Safety compliance refers to the act of adhering to established safety standards, regulations, and laws to protect
students, teachers, and other laboratory users from harm including its environment (Aniodoh, 2022). It involves
implementing policies, procedures, and training programs to ensure a safe and healthy work environment.
The development of laboratory safety compliance involves total commitment from all levels of the educational
sector. At the administrative level, this will include putting a decision or plan into effect such as execution of a
chemical hygiene plan which must address the safe handling, storage, and disposal of chemicals. Eye wash and
showers should be available and also, in good working condition. A conducive laboratory working environment
were risks and accidents, such as loss of life, fire hazard, electrocution among others, are avoided through
carefulness and total safety compliance should be a concern to all users. Hence, the need for this investigation.
Statement of the Problem
A lot of risks are involved during laboratory practical class, which needs to be addressed. Otherwise, there would
be casualty of students and teachers in the laboratory. When safety rules are not obeyed, laboratories are not
safe; they pose danger to teachers and students and other laboratory users. Surely, not much will be achieved if
our present and future scientists are expected to work in laboratories that safety is neglected. Amber (2019),
reported that research assistant died from burns sustained in a university science laboratory in California, when
the plunger popped out of the syringe, she was using to transfer tert-buty lithium. This ignites spontaneously in
air, causing her gloves and jumper to catch fire. He also recorded that, another research assistant, died in Yerkes
Regional primate research center in Georgia due to a chance splash of primate fluids. Because he did not use
safety glasses, a piece of material contaminated with herpes B virus (probably urine or feces) got into her eye
and she died six weeks later. Nwanuma (2021), reported that Ikwo High School science laboratory of Ebonyi
State was once partially burnt as a result of carelessness, improper lighting of the Bunsen burner and lack of fire
safety equipment. For laboratory users and equipment to be free from all these hazards, safety compliance must
be in place and enforced.

Summary of data analysis presented in table 10 indicates that item 30,31, 33,34,35,36,37,38,39 and 40 were not
significant because their individual F. Probability value is greater than Alpha level 0.05. While, item 32 is
significant because its F. Probability value is less than 0.05 Alpha levels. This cluster yielded AVOVA value of
0.38. this implies that levels of compliance to safety measures based on subject areas in Secondary school
Laboratory in Abakaliki Education Zone is significant.
DISCUSSION OF FINDINGS
Findings on level of compliance to safety measures show that laboratory users in secondary schools in Abakaliki
Education Zone, of Ebonyi State comply with required safety measures at high extent in the use of safety goggles,
hand gloves, laboratory coats and avoiding of unauthorized experiments. While, comply at high extent with not
playing, fighting, eating, sitting on laboratory benches, wearing of high heeled shoes and dangling jewelry.
This is in line with the recommendations of Adigun (2015) that science teachers should ensure strict adherence
to laboratory rules and regulations. It is also in line with Nwanna, Baja and Obioha (2010) that science teachers
should ensure that safety rules and regulations in science laboratories are observed by students. On the other
hand, it is contrary with the findings of Ibiam, Ibrahim and Idoko (2008) that there are poor laboratory safety
practices or non-compliance to safety measures in secondary schools in Nsukka Local Government Area of
Enugu State.
Also, findings on level of compliance to safety measures based on subject areas in Secondary school Laboratory
in Abakaliki Education Zone reveal that laboratory users in secondary schools in Abakaliki Education Zone,
Ebonyi State comply with required safety measures based on various subject areas at high extent in the use of
safety goggles, hand gloves, laboratory coats and avoiding of unauthorized experiments. While, compliance is
at high extent with avoiding playing, wearing of high heeled shoes, dangling jewelry and sitting on lab benches

in Biology, Chemistry and Physics laboratories. Avoiding running and eating in the laboratory is at very high
extent in Biology laboratory while is at high extent in Chemistry and Physics laboratories.
SUMMARY OF FINDINGS
The extent of compliance of laboratory users in secondary school science laboratories Abakaliki Education is at
high extent.
The extent of compliance of laboratory users based on subject areas in secondary school science laboratories in
Abakaliki Education is at high extent.
CONCLUSION
Safety is very necessary in all human activities to safeguard lives and property. Therefore, laboratory safety
compliance are essential for the safety of both teachers and students during laboratory activities. Though, the
study showed high laboratory safety compliance, but not same with other schools in different areas. Since,
laboratory safety compliance deals with the safety of lives and property, it should be a must in all science
laboratories.
RECOMMENDATIONS
Based on the findings of this study, the researcher made the following recommendations:
The state government in collaboration with curriculum developers and science teachers should review the
existing curriculum and integrate the basic tenets of laboratory safety compliance and enforcement in the
curriculum. Science teachers and administrators should ensure laboratory safety procedures and precautionary
measures are followed during laboratory activities. Both teachers and students should be encouraged and
sponsored for in-service science laboratory safety training.
