Respiratory ProtectionA wide variety of masks and filters is available for respiratory protection: Use a half or full facial mask with a combination filter (combination of gas/vapour filter with dust/atomization filter). Another effective solution is the use of a hood with air stream filter (air stream helmet), whereby filtered air is blown in the air hood at a slight overpressure. Make sure you use the right filter:
A brown/white filter with code A 2 P 2 (CEN normalization) is suitable for most crop protection chemicals. A 2 P 2 indicates a combination filter offering protection against both gases and vapours derived from the standard spraying agents, as well as against spray and dust from powdered products. A 2 refers to protection class 2 of the gas filter, i.e. that the filter may be used in concentrations up to 0.5 vol%. P 2 indicates that it is a dust filter of protection class 2. A grey/white filter jar with code B is only required when working with hydrocyanic acid or formalin. Check whether the mask seals well before use. Examine for damage and check whether the exhaust valve is clean and well sealed. Write the date of first use on the filter. Make sure the filter A 2 P 2 is replaced once a month, regardless of how often it has been used. The code B filter must be replaced after each spraying job. After opening the seal, the filter must be used within a period of 6 months. Make sure waste filters are disposed in accordance with the statutory regulations. Never judge the effect of the filter by your sense of smell, after all:
