Subject: Application of 29 CFR 1910.212(a)(1) to Food Waste Disposal Equipment

1. Purpose

To assure uniformity in the application of the subject standard to point of operation guarding on food waste disposal equipment.

2. Directive Affected


3. Background

Several inquiries have been made regarding the acceptability of a trimboard as a guard on food waste disposal equipment such as the "Garb-el" or equipment of similar configuration and operational characteristics. The guard in question was inspected and tested. It was determined that the worm screw conveyor operates at approximately 2.4 RPM to 3.5 RPM, depending upon the horse power. It was also determined the hopper is open and free with no narrow throat.

4. Clarification

Based on actual operation, it was determined that a trimboard properly designed and mounted, provides the nip point protection and meets the intent of the standard. Attachment #1 identifies the nip points. Attachment #2 illustrates the proper placement of the trimboard.
