Continuous exposure to dust and inhaling the smell of garbage has the potential to increase the risk of asthma, heart attacks and lung diseases in this group of workers. For this reason, it is obligatory for the workers working in this field to use protective mouth covers and keep in mind that many masks in the market are non-standard and allow dust particles to pass through them, so it is necessary for urban cleaning workers. To ensure the appropriateness of the prepared masks, be sure to consult the pharmacy officials.
