TW 230HB (Petrol)

3.3 Basic Woodchipping Safety
It is the responsibility of the machine operator to carry out a full site Risk Assessment
before starting work. This Risk Assessment should consider the following points:
MAINTAIN A SAFETY EXCLUSION ZONE around the chipper of at least 10 metres for
the general public or employees without adequate protection. Use hazard tape to identify
this working area and keep it clear from debris build up. Chips should be ejected away from
any area the general public have access to.
HAZARDOUS MATERIAL - Some species of trees and bushes are poisonous. The
chipping action can produce vapour, spray and dust that can irritate the skin. This may lead
to respiratory problems or even cause serious poisoning. Check the material to be chipped
before you start. Avoid confined spaces and use respiratory protection where necessary.
BE AWARE when the chipper is processing material that is an awkward shape. The
material can move from side to side in the funnel with great force. If the material extends
beyond the funnel, it may push you to one side. Badly twisted material should be trimmed
before being chipped to avoid thrashing in the feed funnel.
BE AWARE that the chipper can eject chips out of the feed funnel with considerable force.
Always wear full head and face protection.
ALWAYS work on the side of the machine furthest from any local danger (e.g. not road
side).
NEVER leave the chipper unattended when running. Machines must be supervised at all
times when in use.
In the event of an accident, stop the machine, remove the key and call the emergency
services immediately.
