Nov 01, 2001· The 350-employee foundry recently planned and implemented an expansion of its cleaning and finishing area to meet increasing customer demands. One of the main focuses in the new design was silica dust control. Dust Control Acme Foundry wanted to maintain tight control over its silica dust emissions.
With the release of new, updated standard in June 2016, OSHA has renewed the focus on the proper steps required to protect workers from the threat of silica dust. As a leader in dust control, Nilfisk has a full line of well-equipped products to help you safely collect silica dust and keep your crew safe.
Environmental factors also have an impact on equipment decisions. Here are the main points to consider as you set out to design a dust collection system for crystalline silica dust control: Type of capture system: Source capture is the most effective control for process dust emissions. Some form of hood or enclosure is used to control the dust ...

Control of exposure to silica dust: A guide for employees Page 3 of 5 Health and Safety Executive where necessary, provide you with personal protective equipment; maintain all equipment used as control measures in good working order; instruct and train you to use equipment properly, and tell you about health risks; monitor to ensure that controls are effective and that the WEL for RCS is not
Didion’s latest invention is the new Mark 5 Series rotary media drum which performs shakeout, sand conditioning, double sand screening, casting cleaning, and casting cooling in one efficient step, so the foundry stays much cleaner with less airborne silica dust. By combining these processes the foundry can save $40.00-80.00 per ton.
Research shows that dust is a significant health hazard to people working in the construction industry as dust contains known carcinogens and silica. Samantha Wilding, B&CE’s health policy and public affairs lead, states, in The Construction Index editorial , that “81% of the 500,000 people who are exposed to silica dust at work, are ...
Controlling Silica Dust from Foundry Casting-Cleaning Operations Studies conducted by the National Institute for Occupational Safety and Health (NIOSH) have shown that excessive concentrations of respirable silica are produced when cleaning castings are made from sand molds.
Jan 22, 2012· The sand stays in the system where it belongs, so the foundry stays cleaner. Dust collection is efficient due to the small open area of the drum. The Didion requires 75% less dust collection than a vibrating shakeout rated at the same capacity. Counterflow air eliminates fugitive dust from escaping, protecting workers from airborne silica dust.
