2.6 SAFETY INSTRUCTIONS FOR WORK WITH COMPACTION MACHINES
Vibratory plates, vibratory tampers and vibratory rollers belong among compaction machines. When operating
such machines, the following safety instructions have to be observed:

2.7 HYGIENICAL DATA
Noise level:
Declared level of acoustic pressure A at the operator's place
(measured according to ČSN EN ISO 11201 under conditions specified by ČSN EN 500-4+A1, enclosure B).
L
pA,d
Guaranteed level of acoustic power A
en
(measured according to NV č.9/2002 Sb., Enclosure No. 3, part B, point 9c) and ČSN EN ISO 3744).
L
WA,G
Vibrations:
Declared overall level of vibration acceleration transmitted to hand and arm of the operator
(measured according to ČSNENISO 20643 under conditions specified by ČSNEN 500-4+A1, enclosure C).

With regards to the declared value of acoustic pressure at the operator's place and value of vibrations
transmitted to operator's hands, it is mandatory to use protective means effective in the respective level
acoustic pressure or vibrations transmitted to hands, whose values were set up by the contractor by
categorizing the workplaces; this process is stipulated in regulation of the government No. 148/2006 Sb. as
modified later.
Work prescription for working with the reversible plate have to be adjusted in such a way, that they include
technological interruptions leading to interrupted exposition.

Prior to starting the work, find out bearing capacity of the terrain, locations of underground spaces
and paths of underground civil lines, in order to avoid sinking of the machine or damage to the
underground object.
When working close to a building, always consider whether the building cannot be damaged from
transition of vibrations.
When working in trenches, make sure that the sides cannot slide down and bury the operator.
When working on edge of slopes, always work only in sufficient distance from the edge, to prevent
soil slide and/or rolling over or fall of the machine.
Never work with the machine in such inclination, where is a risk of machine rolling over or where
lost of adhesion and uncontrolled sliding of machine may occur.
