SAFETY

How to prevent accidents.

No accident prevention programme is effective without the complete co-operation of the person directly responsible for operating the
machine.
Most of the accidents that may occur in a company, on the job or during transfers are caused by the non-observance of the fundamental
safety rules.
A careful and cautious user is the best guarantee against accidents and is more effective than any type of prevention programme.
