maximum protection approximately 25 dB(A) Requirements regarding provision and use: - Make available at a sound (pressure) level from 80 dB(A) - Allow to wear at a sound (pressure) level from 85 dB(A) - Respiratory hazards and applications and safe use of the different PPE Hazards Oxygen concentration too low Too high concentration of vapours, gases or dust particles Nuisance due to vapour, gas, dust -

- -

Dust filters clog during prolonged use Gas vapor filters become saturated and break down

Use (filter masks) - If the concentration of the contaminant is higher than the limit value - Check whether the protection factor (TPF) used matches the concentration of the contamination and whether the filter is suitable for the gas/vapour or dust to be filtered Use (self-contained respiratory protection) - With less than 19% oxygen in the air - With large and unknown concentrations of hazardous substances in the air Use (self-contained breathing apparatus in confined space) When working where the limit value is exceeded Use (filter respiratory protective equipment) - Disposable mask (Snout): only against dust, not against gases or vapours - Half and full face masks with insert mechanism: only against dust, not against gases or vapours - Half and full face masks (usually made of rubber) with screw edge: against dust and gases or vapours - Full face masks: cover the entire face Operation (air hood as self-contained respiratory protective equipment) - Worn loosely over the head with supports on the shoulders - Air is discharged at the bottom of the hood at the front - Added air is fed into the air cap without obstruction - Added air comes from a compressor through breathing air lines or through breathing air lines or through lines on a fan

Forms

Filter masks with a dust filter Filter masks with a gas/vapor filter Self-contained respiratory protection with breathing air

via bottles or breathing air line Self-contained respiratory protection with fresh air intake

General characteristics - Filter masks clean the air to be breathed - Independent respiratory protection: the clean air from an external source is blown into the mask, for example via bottles, breathing airline or breathing air unit Do not use if oxygen concentrations are too low - Filters have limited use depending on the type of filter, the concentration of products in the air and the amount of air that is inhaled - Dust filters are divided into classes: P1 nuisance dust, P2 harmful dust, P3 toxic dust - Gas vapor filters are classified according to absorption capacity and the type of vapor/gas retained by the filter - Dust filters do not retain gases or vapours Properties (filter masks) -
