Hazardous Area Classification

EngWorks specializes in the hazardous area classification design of facilities handling flammable gases, liquids and facilities handling combustible dusts. Our goal is to ensure that the area classification design is appropriate for the hazard that may exist. This allows you to determine the appropriate operating procedures and level of equipment protection required to achieve a safe working environment.
All our designs are fully documented, allowing you to easily maintain the area classification design over the life of the facility. Each area classification design will include the following:
