Hazard Area
Potential Hazards
Mold Area
Area between the
platens.
Mechanical Hazards
Crushing and / or shearing and / or impact hazards caused by:
Movement of the platen.
Movements of the injection barrel(s) into the mold area.
Movements of cores and ejectors and their drive mechanisms.
Tie bar motion.
Thermal Hazards
Burns and / or scalds due to operating temperature of:
The mold heating elements.
Plasticized material released from / through the mold.
Clamping
Mechanism Area
Mechanical Hazards
Crushing and / or shearing and / or impact hazards caused by:
Movement of the platen.
Movement of the drive mechanism of the platen.
Movement of the core and ejector drive mechanism.
Movement of
Drive Mechanisms
Outside the Mold
Area and Outside
the Clamping
Mechanism Area.
Mechanical Hazards
Mechanical hazards of crushing, shearing and / or impact caused by the
movements of:
Core and ejector drive mechanisms.
Nozzle Area
The nozzle area is
the area between the
barrel and the sprue
bushing.
M
echanical Hazards
Crushing, shearing hazards, and / or impact hazards caused by:
Forward movement of the plasticizing and / or injection unit including
nozzle.
Movements of parts of-the power operated nozzle shutoff and their drives.
Over pressurization in the nozzle.
Thermal Hazards
Burns and / or scalds due to operating temperature of:
The nozzle.
Plasticized material discharging from the nozzle.
Plasticizing and / or
Injection Unit Area
Area from the adapter
/ barrel head / end cap
to the extruder motor
above the sled
including the carriage
cylinders.
Mechanical Hazards
Crushing, shearing and / or drawn-into hazards caused by:
Unintentional gravity movements e.g. for machines with plasticizing and / or
injection unit positioned above the mold area.
The movements of the screw and / or the injection plunger in the cylinder
accessible through the feed opening.
Movement of the carriage unit.
Thermal Hazards
Burns and or scalds due to operating temperature of:
The plasticizing and / or injection unit.
The heating elements e.g. heater bands.
The plasticized material and / or vapors discharging from the vent opening,
feed throat or hopper.
Mechanical and / or Thermal Hazard
Hazards due to reduction in mechanical strength of the plasticizing and / or
injection cylinder due to overheating.
Feed Opening
Pinching and crushing between injection screw movement and housing.
