Health and safety of laboratory science students in Ibadan, Nigeria

Laboratory science students are engaged in laboratory practice under supervision during the course of their training programme. They are exposed to the risk of laboratory-acquired infection and need to be adequately informed and equipped with facilities to protect their health. A questionnaire was administered to laboratory science students to determine their perception of hazards in laboratory practice and the observance of safety codes in their work practices. Of 128 students, 118 completed the questionnaire, a response rate of 92%. Sixty of them (51%) were males and 53 (45%) were females; five students did not indicate their sex. The results revealed that only 34 (29%) of the students use gloves for handling biological samples and 26 (22%) use gloves for handling clinical waste. Ninety-four students (80%) reported that they washed their hands after handling specimens. Eighteen of the students (15%) had been immunised against tuberculosis, 80 (68%) against tetanus, six (5%) against hepatitis B, and 18 (15%) against yellow fever. Ninety-six students (81%) thought the greatest hazard in laboratory practice was harmful biological organisms, while 13 (11%) indicated that chemical agents were the greatest hazard. Virology was thought to be the most hazardous specialty by 41 students (35%) while morbid anatomy was ranked as least hazardous by 48 (41%) of the students. These findings indicate that whilst laboratory science students are aware of the hazards in laboratory practice, this knowledge is not translated to safe practices and students may endanger their health as a result of exposure to laboratory practice. They therefore need to be provided with adequate facilities to protect themselves and adequate supervision to ensure that they imbibe safe work practices during their training years.
