Company purchases dust collection system using safety grant from the Ohio Bureau of Workers’ Compensation.
Allshred Services, a secure destruction firm based in Maumee, Ohio, has purchased and installed a new dust collection system using a safety grant from the Ohio Bureau of Workers’ Compensation.
Air sample tests taken on May 3, 2011, after the mid-April installation of the system, compared with tests taken in November of 2010 show significantly lower particulate levels, which Allshred says are now well below the applicable OEL (occupational exposure level) for PNOC (particulates not otherwise classified) and the more conservative recommended level of 5 milligrams per cubic meter, which is prescribed specifically to prevent upper respiratory symptoms in paper recycling operation workers.
Tom Huth, executive vice president of operations, says, “It’s a relief to have the breathing zones of our workers improved significantly with the addition of the dust collection system. The health and safety of our workers is always a priority, and we will continue to look at ways to better our working conditions.”
The system features 5-inch dust capture hoods that have been installed over each of the 90-degree transfer points as well as at the shredder discharge conveyor on the first shredder, according to the company. The Twin City Fan being used has a 20-horsepower motor. The six filter bags are each 24 inches in diameter and 12 inches long.
Allshred says the filter system is designed for each of the pickups to have a velocity of 5,000 FPM (feet per minute) to evacuate the dust to the filter. The air-to-filter-cloth ratio is 9:1. Each bag is equipped with a zippered bottom for periodic dust removal.
