Ensure all mask components are in good condition before use. The mask must fit tightly and correctly to cover the face, ensuring no gaps on either side of the nose. Tighten the band securely. If a slight harmful odor is detected, leave the area immediately and replace the cartridges. Do not use the mask for firefighting, abrasive blasting, or protection against contaminants not covered by the cartridge. Store the respirator away from dust, chemicals, direct sunlight, extreme temperatures, and excessive humidity to prevent damage or deformation. Read the usage instructions carefully to avoid possible accidents. Users are responsible for any consequences. Safety Kit
