NEMA Division 2 Hazardous Location Motors

Class 1, Division 2 motors are used in areas where hazards are present only under unusual circumstances. They are crucial for industries where the normal operation of electrical equipment could cause ignition, leading to explosions or fires. These motors help promote personnel safety and protect valuable assets in high-risk environments.

Dietz Electric offers a diverse range of specialized motors, including those used in Class 1, Division 2 hazardous locations. Our commitment to quality and safety is reflected in our products, ensuring reliable performance across various applications.

What Are Class 1, Division 2 Hazardous Locations?

Class I, Division 2 refers to a location that falls under one of the following criteria:

  • It involves the handling, processing, or using of volatile flammable liquids or gases. However, they are typically enclosed within closed containers or systems. Escape is only possible during accidental rupture, breakdown, or abnormal equipment operation.
  • It is a space where ignitable concentrations of gases or vapors are normally prevented through positive mechanical ventilation. Nevertheless, there is a potential hazard if the ventilation equipment fails or operates abnormally.

This motor classification commonly encompasses locations where volatile flammable substances are used. However, it is determined by the authority having jurisdiction that these locations would only become hazardous in case of an accident or unusual operating conditions.

Several factors are considered in determining each location’s classification and extent. These may include the quantity of dangerous material that could escape accidentally, ventilating equipment effectiveness, and total area.

Piping lacking valves, checks, meters, and similar devices typically does not introduce a hazardous condition, even when used for dangerous liquids or gases. Moreover, locations that store hazardous liquids or liquefied/compressed gases in sealed containers are generally not considered dangerous conditions.
