Using and Maintaining Respirators Properly<\/strong><\/h3>\n

When properly used and maintained, respirators can protect the respiratory system from pesticide exposure, preventing serious medical harm or even death. However, if used incorrectly or improperly maintained, they offer only a false sense of security. Respirators themselves may even pose a health risk to certain individuals.<\/p>\n

That\u2019s why it\u2019s important to get medical clearance before wearing a respirator, to make sure it\u2019s the right respirator for the job, and to use the only respirator makes, models, styles, and sizes for which one has been fit-tested and trained to use. It\u2019s also critical to read and follow the respirator manufacturer\u2019s directions and the pesticide label.<\/p>\n

Different respirators are necessary for different pesticides and concentrations. A respirator less protective than those listed on the label will not prevent all\u2014if any\u2014exposure. Neither will be using the wrong filter, cartridge, or canister.<\/p>\n

Always refer to the label<\/strong> of the specific pesticide product being used to determine which respirators, filters, and cartridges are acceptable.<\/p>\n

When in doubt, consult a respirator manufacturer to help find the right respirator for the situation. Always read the respirator manufacturer\u2019s instructions carefully before wearing a new respirator.<\/p>\n
