Final answer:
A hazardous class location is one where there are sufficient quantities of combustible dust in the air to cause an explosion or ignite hazardous materials. This is a concern in industries with combustible dust particles, such as manufacturing plants or grain storage facilities. Following safety procedures is crucial to prevent accidents.
Step-by-step explanation:
A class location that is considered hazardous is one in which there are sufficient quantities of combustible dust in the air to cause an explosion or ignite hazardous materials. This is a concern in certain industries or workplaces where combustible dust particles can be present, such as manufacturing plants or grain storage facilities. Ignition sources like sparks or open flames can trigger an explosion in these locations.
For example, in a grain storage facility, if there are large amounts of grain dust in the air and a spark from a machine or electrical equipment comes into contact with the dust, it can cause a dust explosion. The same principle applies in other industries where combustible dust is present.
It is important to follow safety procedures and guidelines in these hazardous locations to prevent accidents and ensure the safety of workers and the surrounding environment.
