What you may think is a hazardous location may not be what the National Electrical Code (NEC) considers a hazardous location. There is no way powdered sugar can create a hazardous location, right? Of course, this area is not a hazardous location because an explosive atmosphere is not present. If I were in a hazardous location, I would be required to wear special articles of clothing. An outdoor area cannot possibly be a classified location. If you were in a hazardous location you would know it, wouldn’t you?
Sound familiar? Then you could be in a hazardous location without knowing it.
Knowing that an area is hazardous is the only way to minimize the potential for an incident and the only way to know is by properly classifying the area.
