Article Synopsis
- - The study investigates respiratory exposures of US home care aides to harmful chemicals while using different cleaning and disinfecting products during bathroom cleaning, focusing on VOCs and QACs present in these products.
- - A total of 22 aides tested three cleaning products: bleach-based, QACs-based, and a "green" product, with air sampling conducted to measure VOCs and QACs in a controlled environment.
- - Results showed the presence of 38 unique VOCs, with many not listed on product labels, highlighting potential health risks due to limited toxicity information and occupational exposure limits for the identified chemicals.
Background: Sporicidal products containing hydrogen peroxide (HP), peracetic acid (PAA), and acetic acid (AA) are used widely in multiple industries, including healthcare. Despite widespread use in healthcare, few studies have assessed associations between exposures to HP, PAA, and AA, and work-related symptoms in these settings.
Methods: In 2018, we performed a health and exposure assessment at a hospital where a sporicidal product consisting of HP, PAA, and AA, was used as the primary cleaner on hospital surfaces.
Article Synopsis
- * A survey of employees at a midwestern Veterans Affairs healthcare facility revealed that nurses and environmental service workers had the highest exposure to cleaning products like bleach and quaternary ammonium compounds.
- * While most workers reported high glove usage during cleaning, certain groups (like administrative and maintenance staff) could improve their protective practices, suggesting a need for better training and workplace interventions.
