In which class and division are locations that handle easily ignitable fibers and combustible materials categorized?

• A. Class 1 Division 1
• B. Class 2 Division 2
• C. Class 3 Division 1
• D. Class 4 Division 1

Answer: (C)

Locations that handle easily ignitable fibers and combustible materials are categorized under Class 3 Division 1. This classification specifically addresses areas where combustible fibers, such as dust or lint, are present in sufficient quantities, posing a potential fire hazard. In Class 3, Division 1 environments, the presence of these materials can create an explosive atmosphere under normal conditions, especially when they accumulate and become airborne. The classification system serves to inform safety measures, regulations, and requirements needed to mitigate risks in environments with a higher potential for combustion. In Division 1, the likelihood of a flammable or explosive atmosphere existing during routine operations is significant, necessitating stringent safety protocols and equipment designed to reduce ignition risks. This classification is distinct from the other classes and divisions, which are concerned with different types of materials or conditions. For example, Class 1 deals with flammable gases and vapors, while Class 2 focuses on combustible dusts. Therefore, understanding the specific characteristics of Class 3 Division 1 helps ensure appropriate safety measures are in place for handling ignitable fibers and combustible materials.
