Change of work methods
- in building demolition, replace use of ball machine with selective demolition;
- replace pneumatic tools by changing manufacturing methods, such as moulding holes in
concrete rather than cutting after production of concrete component;
- use remote control of noisy equipment such as pneumatic tools;
- separate noisy workers in time, but keep noisy operations in the same area, separated
from non-noisy processes;
- select slowest machine speed appropriate for a job - also select large, slow machines
rather than smaller faster ones;
- minimise width of tools in contact with workpiece (2 dB(A) reduction for each halving
of tool width);
- woodchip transport air for woodworking equipment should move in the same direction
as the tool;
- minimise protruding parts of cutting tools.
