Concrete block and brick manufacturers produce masonry units from cement, aggregate, sand, and water using automated mixing, molding, and curing equipment. Products are typically sold to masonry contractors, building supply distributors, and construction material dealers. Operations generally involve heavy machinery, raw material storage, batch plants, and on-site loading for delivery.
Questions to investigate
- What is the total production workforce, and are silica dust monitoring or respiratory protection programs in place?
- Does the operation own delivery trucks, and if so, how many and what type?
- What is the estimated replacement value of production equipment, including batch plants and molding machinery?
- Are there any environmental permits, compliance orders, or prior pollution-related incidents at the facility?
