Which precaution should be taken when using dusters?

Wearing an approved respirator in enclosed spaces is an essential precaution when using dusters. The primary reason for this is that dust insecticides can release fine particles into the air, which, when inhaled, can pose significant health risks to the applicator. Enclosed spaces limit airflow and can cause harmful concentrations of pesticide dust to accumulate, increasing exposure risks. By wearing a respirator, the applicator can significantly reduce the inhalation of these potentially hazardous substances and maintain a safer working environment.

Other precautions, such as applying dust in living areas or leaving dusters unattended, can lead to improper application or increased risk of exposure to others in the vicinity. Additionally, increasing air currents in the treatment area could disperse the dust away from targeted infestations instead of ensuring effective treatment, making it a less desirable option.
