– SECURITY AND FOOD HYGIENE
7.1 PREMISE
The analysis of the below recalled dangers is based on:
•
The knowledge of the normal conditions of use of the machine, specified in the manual;
•
On the presupposition that the machine is destinated to a working place for the production, including
cooking, of bakery products;
•
On the presupposition that the workers have been sufficiently instructed on the specific risks inside
the working place;
•
On the presupposition that the working place is precluded to non-workers and outsiders.
7.2
MECHANICAL DANGERS AND OTHER RISKS
According to the EC directive 98/37/EEC below we recall the areas of residual risks, the analysis of the
risk and the measures necessary to limit their consequences.
•
The risk of entrapping, pulling and squeezing of hands between the mixing arms.
All the area delimitated by the bowl has been protected by an inox protection guard that prevents
arms to reach the mixing arms. The residual spaces between the body and the bowl have been closed
with inox steel guards, well fixed to the body.
The mixing arms can move only with the protection guard closed. The maximum distance between
the bottom of the protection guard and the rim of the bowl must not exceed 25 mm. The protection
guard is connected to a microswitch with contacts closed and whenever one tries to open it, a
mechanical action compels the forced opening of the contacts of the microswitch. The microswitch
itself, at the opening of the contacts, makes the electric current to the motor be cut off and, at the
same time, the breaking system operate.
The safety microswitch must intervene when, in case of the opening of the
protection guard, the opening between the protection guard and the rim of the
bowl exceeds 75 mm.
•
Risk of dragging and abrasion of hands betweeen the fixed structure of the machine and the
rotating bowl.
As such risk can occur only if the operator forces the passage of the hand and the wrist between the
fixed structure and the bowl, otherwise there would be no possibility of dragging, and as there is no
real reasons why the operator should do so, the only signal of ranger applied is the one illustrated
below:
No one however is authorized to place the hand/s in the above area of risk while the machine is on.
For the cleaning operations of the area and under the bowl one must follow the instructions recalled
in chapter 6 – paragraph 6.1.
