scope:

This International Standard specifies the safety requirements and their verification for the design and
construction of knapsack mistblowers incorporating a combustion engine.
It describes methods for the elimination or reduction of hazards arising from their use. In addition, it specifies the type of information on safe working practices to be provided by the manufacturer. It does not however give any technical requirement to reduce noise and vibration hazards. Indeed the different means available to reduce these hazards are a matter for the technical aids to which the manufacturer may resort, through specialized books or specified bodies.
This International Standard deals with all the significant hazards, hazardous situations and events excepting environmental hazards and hazards arising from electromagnetic compatibility, noise and vibrations relevant to knapsack combustion engine driven mistblowers, when they are used as intended and under the conditions foreseen by the manufacturer (see Clause 4).
This International Standard is not applicable to knapsack combustion engine driven mistblowers which are manufactured before the date of this document by ISO.
