The outer barrier is plastic netting or equivalent to discourage access by the
public or their pets within the permitted safe distance. The distance of 10m is
twice that recommended as the safe minimum distance from a chainsaw operator.
10m has been chosen in order to reduce the risk of excessive noise exposure to
the onlookers and bring it to within acceptable levels.
If required,
a fine netting screen can be erected around the demonstrator of 1cm square plastic
monofilament net (of the type used to protect fruit bushes etc. in gardens) or
equivalent set up to approx 2m high. This is to prevent the lighter slivers of
wood removed during carving from flying off into the crowd.
There should
ideally be a "blank" side (vehicle being used for this purpose on the
site plan) so that the operator can direct any cuts that may result in flying
debris, away from the onlookers. The operator can also utilise this area for refuelling
and chainsaw maintenance.
Examples of previous work can be displayed
within the outer barrier if of a delicate nature or if they may pose a risk to
the onlookers (e.g. If they might easily fall over, or have projecting elements
that could cause injury). Anything else can be placed on display just outside
the barrier.
All barriers supplied by and set up by chainsaw demonstrator
and/or assistant.
