ABSTRACT
Aims Hand sanitizers are increasingly used in most households since the onset of the COVID-19 pandemic. However, improper use and accidental and deliberate ingestion of sanitizer solutions have been associated with numerous health risks to children. This study aimed to assess knowledge and practices regarding safe handling and disposal of alcohol-based hand sanitizers and surface disinfectants among a cohort of parents in urban Sri Lanka. Methods This observational cross-sectional study was performed including parents of children admitted to North Colombo Teaching Hospital for a period of six months from August 2021. Data were collected regarding parental knowledge regarding safe handling and disposal of hand sanitizers, and their health hazards by paediatric post-graduate trainees. Data were collected using a pre-tested interviewer administered questionnaire. All data were analysed using SPSS 17.0. Results Out of 153 children recruited to the study, the mean age was 5.3 years (range: 1 month - 14 years) and male children (92, 60.1%) outnumbered female children (61, 39.9%). The majority of mothers (126, 82.4%) and fathers (133, 86.9%) had received education at least up to secondary school. 124 parents (81%) had been using hand sanitizers at home regularly. Only 113(73.9%) parents believed that preschool children were the most vulnerable for accidental ingestion of sanitizers and 40 parents (26.1%) were unaware that sanitizer solutions can be accidentally inhaled by toddlers. Knowledge was poor regarding occurrence of potential symptoms and side effects such as sore throat (56, 36.6%), irritation of eyes (30, 19.6%), breathing difficulties (40, 26.1%), high heart rate (72, 47%), aspiration (43, 28.1%) and low blood sugar (108, 70.5%). Only 132 parents (86.2%) knew how to clean and disinfect their home premises safely and 29 parents (18.9%) didn't know how to store cleaning products safely. Sixty-four parents (41.8%) were unaware regarding how to get information on safe cleaning practices. Forty-two parents (27.4%) kept sanitizer bottles within easy access to children whilst 85 parents (55.5%) had been storing sanitizers in unlabeled bottles. Ninety-eight parents (64%) were not keen to read the signage alerts in sanitizer storage bottles. Only 25 parents (16.3%) safely disposed sanitizer bottles. Thirty-three parents (21.6%) put sanitizer bottles together with food items in carriage bags from super markets. Conclusion The findings of this study inform that knowledge in parents regarding safe use of sanitizers can further be improved specially, in areas of local and systemic effects of sanitizer poisoning and information resources of safe cleaning practices. As a number of parents use and dispose hand sanitizers unsafely, the effectiveness of awareness programs to improve safety practices among parents should be evaluated.
