Static Grounding and Bonding in Aircraft Refueling

These flashcards cover key concepts related to electrostatic hazards, grounding, bonding, refueling operations, and safety measures to minimize risks during aircraft servicing.

Grounding

The process of connecting metallic objects to ground electrodes to control electrostatic hazards.

Bonding

The connection of two or more metallic objects together to equalize electrostatic potential.

Electrostatic Charge

Static electricity generated when two materials come into contact and then are separated.

Stray Currents

Electrical currents flowing through unintended circuits, which can pose hazards even when systems are grounded.

Combustion Requirements

The presence of fuel vapors, air (oxygen), and an ignition source is required for combustion.

Vapor Ignition Hazard

The risk of ignition from fuel vapors during fueling operations.

Humidity Effect on Static Electricity

Lower humidity conditions increase the likelihood of electrostatic charge accumulation.

Insulative Footwear

Footwear that limits the dissipation of static charges to the ground.

Static Discharge

The sudden flow of electricity between two electrically charged objects.

Lightning Hazard

The risk posed to servicing personnel by lightning striking aircraft or nearby areas.

Refueling Safety Zone

The area around an aircraft during fueling that is free from non-essential personnel to ensure safety.

Multiple Source Refueling

Using multiple refueling trucks or hydrants simultaneously to service aircraft.

Hydraulic and Oil Servicing

The processes involving the maintenance of hydraulic fluids and oils in aircraft systems.

Liquid Oxygen (LOX)

A pale blue liquid that is highly reactive and can create a fire hazard when in contact with petroleum products.

Nitrogen Servicing

The use of nitrogen for expelling gases from cylinders or purging lines.

Hydrazine

A toxic chemical used in aircraft systems that poses fire hazards and requires stringent handling procedures.

De-icing Fluid Operations

Applying de-icing fluids to aircraft while ensuring no fuel servicing or LOX equipment is nearby.

Tire Servicing

Inflating aircraft tires, which requires adherence to specific safety guidelines due to high pressure risks.

Chemical Warfare Defense Ensemble (CWDE)

Protective clothing that allows for grounding without removal during refueling operations.
