We require a liquid dust inhibitor designed to reduce dust on a 3 miles gravel road obstacle course. This solution must be a liquid capable of being sprayed through an agriculture spray bar. Liquid dust inhibitor must also comply with rigorous health, safety, and chemical standards. The product must be free from any ingredient, at concentrations of 0.1% or higher, that is classified as a probable or confirmed human carcinogen by the International Agency for Research on Cancer (IARC), a carcinogen or potential carcinogen by the Occupational Safety and Health Administration (OSHA), or a known or anticipated carcinogen by the National Toxicology Program (NTP). Additionally, the product should exhibit specific physical properties, including a pH value between 5.5 and 7.0, a freezing point ranging from 30�F to 32�F, a boiling point between 210�F and 214�F, and a density of 8.500 to 9.200 pounds per gallon. This dust inhibitor is intended for use in managing dust effectively while prioritizing safe handling and adherence to environmental compliance standards.
