This occupancy is a use that involves the manufacturing, processing, generation or storage of materials that can constitute a physical or health hazard. Group H occupancies are classified into 5 high hazard areas that identify the type of hazard for each group. Here we feature a chemical storage facility in Mexico, compressed fuel gas distribution in Minnesota US, and high-voltage electricity distribution controls in New Hampshire US. Our gallery includes only a few examples of the many and varied assignments we have completed over the years.
