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.
