Health director-general Dr Noor Hisham Abdullah has cautioned against using nano mist spray directly on humans, as it could lead to health concerns.

"The effectiveness of this device is dependent on its dispersion ability, the disinfectant type used and its concentration, as well as the contact time between disinfectant and surface," he said in a statement, reported The Star.

According to him, several surface disinfectants have been proven to be effective against the SARS-CoV-2 virus, such as alcohol 70%-90%, hydrogen peroxide, thymol, quaternary ammonia, as well as chlorine-based solutions.

However, these solutions are more suitable to used to sanitize surfaces and not on the human skin, he added.

This is because direct contact with the solution may cause eye or skin irritation, as well as respiratory and gastrointestinal system problems, Noor Hisham noted.

Cordless and rechargeable spray guns have become popular during the COVID-19 pandemic. While some shops use the guns to sanitize surfaces, some use on visitors and customers.
