hazardous location lighting.

The National Fire Protection Association (NFPA), National Electric Code (NEC) 70, defines hazardous locations through a system of classes, divisions or zones, and groups that products must be labeled as to be used in those areas. Hazardous area classifications are based on the general type of substance or material that is present in the area, the likelihood that it exists, and more detailed specifics, such as ignition temperatures and combustible properties.

Class I:

A Class I hazardous location contains flammable gas, liquid-produced vapors, or combustible liquid-produced vapors that can be present in quantities large enough to create an explosion.

Typical locations include airplane hangars, vehicle paint shops, commercial laundromats, and gas plants.

Class III:

This type of location contains easily ignitable fibers or flyings in the air but that aren’t likely to be in suspension in amounts large enough to cause an explosion.

Typical locations include textile mills, cotton mills, and sawmill facilities.

Electrical wiring and materials have improved significantly over the years, but if you live in a house in which the wiring was laid a long time ago, there may be some risks involved. It is worth checking to see whether everything is as it should be.

Electricity is normally out of sight and out of mind because the cables are hidden in the walls and in switches and sockets. As a result, we rarely check the condition of our electrical installations. Faulty and aging wiring can cause electrical fires, but you can avoid this by having your electrician check them for you.

There are clear indications that can make it easier to identify aging cables. Any cables that are coated in black rubber will be quite old as they were phased out in the 1960s; the same applies to fuse boxes with wooden backs and cast-iron switches. These were also phased out in the 1960s.

During your inspection, you may see wires that look old but are intact. These will likely be safe to use. You will need to check any connections wrapped in friction tape to ensure that the tape is not unraveling or frayed. If the tape is damaged, turn off the circuit and replace it with new tape.

The biggest disadvantage with most old wires is that they do not normally implement ground wires. This may result in a person becoming the path to the ground and being electrocuted if there happens to be a short in an appliance.

The term “arc flash” is used to describe low impedance connections in an electrical system, which allows movement of unwanted electric discharge through the air from one voltage phase to another, or to ground. This leads to a rapid rise in temperature and pressure in the air between electrical conductors, causing an explosion known as an arc blast.

Arc blasts and the resulting heat can lead to fires, pressure waves and flying shrapnel that result in serious damage to life and property. These explosions typically occur without any warning, destroy electrical equipment completely and lead to severe injury or death of personnel present within the boundary of the arc flash.

What Are the Main Causes of Arc Flash?

Arc flash occurs when several electrical conductors are placed close to each other, with significant fault currents flowing through them. In this situation, ionization of the air can take place as a result of various factors – such as differences in potential – which leads to a low resistance path and allows current to flow through the air gap between conductors.

Many people assume that low voltage equipment is safe from arc flash, but arc flash hazard levels may be higher at low voltages, due to the high fault currents. Most incidents that occur in low voltage systems are caused by human error, e.g. a tool slipping while a technician works on electrical equipment.

Arc flash can also be caused due to:
