2.2. Safety Requirements at the Workside

The following aspects have to ALWAYS be checked at the workside BEFORE using the Danfoss drilling device !
For drillings in district heating pipelines in Germany, the AGFW directive 432 has to be considered.
• ALWAYS make sure that it is possible to close the chosen Hot Tapping valve ! If the shutting
mechanism cannot be closed, the only way to remove the drilling device is to empty the main line.
• Double check the size of the used hole saw and pilot drill! Check that the valve closes after the
machine is assembled !
• Familiarize yourself with the Danfoss data sheet for the chosen valve type
• Make again sure that the technical parameters (pressure, temperature, fluid) in the system are not
exceeding the allowed values given in this user manual for the specific application
• Check that the device is assembled correctly as shown in this user manual
• Always make a pressure test to discover possible leakages at the shut-off valve and/or the drilling
device
• Make sure that all the rotating parts move freely
• Inspect the device according to the inspection plan given in this user manual
• Tell unauthorized person to leave the workside
• Check the location of the closest network shut-off valve at the workside
• Make sure you know all emergency contacts. This concerns the contact persons on side, the contact to
the device manufacturer TONISCO System Oy (http://www.tonisco.com) and the local emergency services
• Visual check the workside and take all the necessary measurements. Clean the work environment
from all unecessary objects. Consider especially the distance for removing the shaft
• Make all the necessary tools and equipment is available while drilling (e.g. chain block at high
pressures)
