safety regulations must be adhered to. Where applicable, ventilation must be
provided or the instrument must be operated under an exhaust hood.
 When oxidizable materials such as metals, organic materials, wood, coal, plastic, etc. are
ground or sieved, the risk of spontaneous ignition (dust explosion) exists whenever the fine
particles exceed a specific percentage. While such materials are being
ground, it is therefore necessary to take special safety precautions (e.g. wet
grinding) and the work must be supervised by a specialist.
 The instrument is not explosion-proof and is unsuitable to grind or sieve
materials which are explosive, combustible or promote combustion.
