Electrical hazards

Integrated services bonding projects are an effort to identify and communicate to concerned parties the hazards associated with electrical systems to served facilities. It also gives ideas on how to control, mitigate, or eliminate them.

Here is an incomplete list of hazards that we must be concerned with.

1. An electrical shock or "tingling" is felt under the following circumstances:

In the shower.
In the bathtub.
At any sink.
Washing dishes.
Moving wet clothes from washer to dryer.
Adults, children or animals complain when walking barefoot, whether indoors or out.

2. False sense of security based on weak or nonexistent components. All can be strengthened with periodic monitoring, improvements, and repair:

An Electrical Power Service Entrance (ESE) alone offers minimal protection.
Grounding Electrode Conductor (GEC).
Integrated Services Bonding Point (ISBP).
Grounding Electrode System (GES).
A collapsed or weak Grounding Cone of Protection (GCP).

3. Missing electrical ground.

4. Presence of an improperly grounded neutral conductor.

5. Flashover, especially indoors. Flashover is defined as the event when electrical current jumps across two points having different voltages. It can begin from either of the two points at different times. Flashover is an attempt to balance out voltages across two points: electrons are trying to pool evenly and are jumping a gap to achieve this.

5.a. The National Electric Code, in common with many other electrical installation guidelines, seeks to keep flashover sites and events away from populated areas, such as indoors in a facility, in the interest of fire and electrical safety where life and property can be at risk.

5.b. Intended flashover is a planned event. It is designed to complete a circuit, it can solve a specific problem, and it can be dangerous if not safely and deliberately controlled or mitigated.

5.c. Unintended flashover is an unplanned event. It is the electrical event least understood by consumers, it is usually not expected, it is almost always not wanted, it can be a traumatic and traumatizing event, and it is the most dangerous and poses the most risk.

5.d. Flashover commonly crosses a boundary of insulating material such as air or wood. The insulating skin and conductive bodies of people and animals is also a target of flashover.

5.e. Flashover manifests itself as a flash of light; arcing; sparking; crackling, buzzing, or humming sounds; high heat; strong odor; even visible damage such as burns, breaks, or blackened (carbonized)
