When the hopper is in place, it guards the feed throat opening (which connects the hopper to the injection unit) and prevents insertion of a hand or limb into the area where the screw is turning. Wear appropriate personal protective equipment (PPE) and, where possible, use shields to protect employees from splatter. Safety signs should be posted to alert workers of potential hazards. If servicing and maintenance is needed, follow appropriate lockout/tagout procedures. [Photo description: Highlighted area includes the hopper guard.] View close-up

The movable rear guard should be equipped with at least two interlocks that stop clamp motion when the guard is open. This guard should only be opened for setup and maintenance activities, which require lockout/tagout. Use the front operator’s gate for operator access to the mold space.

The movable guard prevents access to the clamping and ejector mechanisms as well as other moving portions of the machine and mold. Do not start up or leave a machine operating unless this guard is in place. For some machine designs, this guard may be fixed, requiring a tool to remove.

Hoses and fittings can fail and spray hot oil or other substances at high pressure onto workers if punctured, frayed, or damaged. In addition, oil sprays can cause injuries and fire hazards. Inspect hoses and fittings for wear and damage as recommended by the manufacturer and replace as needed. [Photo description: Highlighted area includes hoses and fittings.] View close-up
