Our History
Manufacturing environments in the 1920’s were vastly different from today’s modern, efficient and highly regulated facilities. Most had overhead line shafts and creosote wood floors saturated with oils and cutting liquids and few, if any of these facilities had sprinkler protection. Gasoline, naphtha, kerosene and carbon tetrachloride were common cleaning agents. Most were potential fire hazards and all released harmful vapors into the atmosphere endangering employee health.

Today
Public awareness of environmental issues and the development and enforcement of “clean air” regulations fueled rapid growth of the company. In recent years, Protectoseal has taken a strong leadership role in promoting the safe operation of vapor recovery systems. Active participation in the drafting of international, industry-wide regulations, focused research and testing and the development and marketing of products such as detonation flame arresters and tank blanketing valves were all aimed at solving customers’ tank safety problems.
