Slitters | Safeguarding for Specific Types of Machinery

Slitters use rotary knives to slit flat rolled metal, plastic film, paper, plastic, foam, and rubber as well as other coiled or sheet fed materials. Slitters range from small hand-fed paper slitters to large-scale automated metal slitters, complete with metal processing and handling units such as unwinders and rewinders. Both light and heavy gage slitters are available.
Slitter hazards
Add a note hereAmputations often occur when clothing or body parts come in contact with slitter blades or get caught in the movement of coils and rolls. Here are some example:
§  Add a note hereWorkers can inadvertently get their fingers and hands caught in the in-going nip points of the slitter or associated machinery such as rewinders.
§  Add a note hereGloves, jewelry, and loose clothing can get entangled in in-going nip points or in the rotary knives of the slitter.
§  Add a note hereWorkers can suffer an amputation when clearing, adjusting, cleaning, or servicing the slitter while it is either still operating, or shut off but still plugged in (energized).
Case History 
Add a note hereAn employee was feeding cardboard strips onto slit steel as it was being coiled on a slitter machine. While the machine was operating, the employee was placing the cardboard strips on the coils. After reaching over the steel strips, the coiled steel on the mandrel pulled his right arm into the machine and amputated it.

Slitter machine safeguards
Add a note hereYou can use guards and other engineering controls such as the following:
§  Add a note hereInstall a fixed or adjustable point of operation guard at the in-feed and out-feed section of the machine.
§  Add a note hereInstall a fixed point of operation guard to cover the sides of the unwinder/rewinder to prevent an employee’s hands or clothing from entering into the rollers.
§  Add a note hereInstall fixed or interlocked guards to cover other moving parts of the machine such as the power transmission apparatus.
§  Add a note hereUse an awareness barrier guard with an interlocking gate around the perimeter of the machine to prevent unauthorized entry.
§  Add a note hereProvide guards for operator control stations to prevent inadvertent activation.
Work practice and administrative controls
Add a note hereYou can also implement work practices and administrative controls to help do the following:
§  Add a note hereDevelop and implement safe work procedures for machine operators and conduct periodic inspections to ensure compliance.
§  Add a note hereEnsure that all operators receive appropriate on-the-job training and supervision until they can work safely on their own.
§  Add a note hereInstruct employees to perform servicing and maintenance activities under an energy control program in §1910.147.
