Gun length and health and safety

Are there any special regulations regarding gun length?

Answered by our Service Manager:

Yes. For safety reasons, the total length of a gun including lance and nozzle must never be less than 1000 mm. A shorter gun would drastically increase the risk of accident or injury, due to the higher danger of limbs coming into contact with the jet of liquid. The German Trade Association Regulations for Health and Safety (Berufsgenossenschaftliche Regeln für Sicherheit und Gesundheit) state in regulation BGR500 - 3.7.6:

When handling spray devices, hands or other parts of the body must not be placed in front of the pressurised nozzle or under the jet of liquid. Contact with the jet of liquid may cause special health hazards. In addition to skin abrasions and penetrating injuries, partial amputation of limbs may occur.

This notwithstanding, when cleaning drains and sewers in particular, care should be taken to ensure that guns are of sufficient length as the confined space means that the risk of accident is, in any case, much higher.
