Safety Instructions for Work with Compacting Machines
Compacting machines are vibration plates, vibration (jumping) rammers and vibration rollers. When
working with these machines, the following safety instructions should be followed:
1.
Before work, evaluate the bearing capacity of the terrain, locate the places of underground spaces
and underground services to prevent caving-in the machine or damaging the underground
structures.
2.
When working with the machine close to buildings and structures, bear in mind the possibility of
damaging the buildings or structures by vibrations.
3.
When operating the machines in excavation pits, secure the walls of the pit to prevent them from
sliding and causing injury to the operators.
4.
When operating the machines on embankments, do not work on the very edge of the embankment
so that it should not slide down causing turning the machine over.
5.
It is strictly prohibited to operate the machine on such slopes where there is danger of turning the
machine over or of loss of adhesion resulting in an uncontrolled skid of the machine.

With regard to value of declared level of acoustic pressure in operator´s area and value of vibrations
transferred to operator´s arms, when operating particular type of vibratory plate it is necessary to use, in
accordance to Government regulation no. 272/2011 Sb. in valid version, personal protection equipment
effectual in such level of acoustic pressure or vibrations transferred to arms, whose values for particular
type of vibratory plate are determined by machine operator by workplace categorization.
Manuals for operation of vibratory plate must be modified so, that there are obvious technological pauses
leading to interruption of operator machine usage.
