An answer normally denies some or all facts asserted by the complaint and may sometimes include counterclaims of allegations or charges against the plaintiff. A defendant usually has 30 days to file an answer after being served with the plaintiff’s complaint.
AOE/COE (Arising out of and occurring in the course of employment): Injury caused by and happened while on the job.
Appeal: Request to a higher court to reverse the decision of a trial court after final judgment or other legal ruling, citing legal reasons for overturning the ruling. No new evidence is admitted on appeal, for it is strictly a legal argument.
Appeals Board: A group of seven commissioners appointed by the governor to review and reconsider decisions of workers’ compensation administrative law judges.
Applicants’ Attorney: A lawyer that can represent the injured worker in a workers’ compensation case.
Apportionment: A way of figuring out how much of your permanent disability is due to your work injury and how much is due to other disabilities.

Circuit: The path along which electric current flows from start to finish is called a circuit. The circuit includes the generator or battery which starts the current, the wires, and any electrical device that the current operates. If any part of the circuit is removed, the current cannot flow. The circuit is then broken or open. Because electric current seeks to complete its circuit, it will travel along any path that is presented (path of least resistance), which is why humans are at risk of electrocution when they handle damaged tools or cords, or contact un-insulated wires. In effect, they become part of the circuit.

Current: The flow of electrons through a conductor, measured in amperes (amps). If the current flows back and forth through a conductor, it is called alternating current (AC). If the current flows in one direction only, as in a car battery, it is called direct current (DC). AC is most widely used because it is possible to increase (“step up”) or decrease (“step down”) the current through a transformer. For example, when current from an overhead power line is run through a pole-mounted transformer, it can be stepped down to normal household current. Also, alternating current can travel enormous distances with little loss of voltage, or power.
Cycle: When alternating current flows back and forth through a conductor, it is said to cycle. In each cycle, the electrons flow first in one direction, then the other. In the United States, the normal rate for power transmission is 60 cycles per second, or 60 Hertz (Hz).
Dangerous Goods: The term used in TDG regulations to describe hazardous materials.
Date of Injury: If your injury was caused by one event, the date it happened is the date of injury. If the injury or illness was caused by repeated events, the date of injury is the date you knew, or should have known, the injury was caused by work.

Deceleration Device: Any mechanism, such as a rope grab, rip-stitch lanyard, specially-woven lanyard, tearing or deforming lanyard, automatic self-retracting lifeline/lanyard, etc., which serves to dissipate a substantial amount of energy during a fall arrest, or otherwise limit the energy imposed on an employee during fall arrest.
Deceleration Distance: The additional vertical distance a falling employee travels, excluding lifeline elongation and free fall distance, before stopping, from the point at which the deceleration device begins to operate. It is measured as the distance between the location of an employee’s body belt or body harness attachment point at the moment of activation (at the onset of fall arrest forces) of the deceleration device during a fall, and the location of that attachment point after the employee comes to a full stop.

Personal fall arrest system: A system used to stop an employee in a fall from a working level. It consists of an anchorage, connectors, a body harness and may include a lanyard, deceleration device, lifeline, or suitable combinations of these. As of January 1, 1998, using a body belt for fall arrest is prohibited.
Petition for reconsideration: A legal process to appeal a decision issued by a judge.
Phase: In AC power systems, load current is drawn from a voltage source which typically takes the form of a sine wave. Ideally, the current drawn by the loads in the system is also a sine wave. With a simple, resistive load such as a light bulb, the current sine wave is always aligned with the voltage sine wave. This is called single-phase. A single-phase power system normally uses three wires, called hot, neutral, and ground, and the voltage is typically 120/240. Most home and office outlets operate in this manner. With some loads, such as motors, and in high voltage systems, the current sine wave is purposely delayed and lags behind the voltage sine wave. The amount of this lag is expressed in degrees and is called a phase difference. A common example is three-phase power, where the system has three “hot” wires, each 120 degrees out of phase with each other.
Physical Hazard: A hazard that is neither biological nor chemical but that exists around us, or because of the things we do. Eg.: weather and personal work habits.

Protective system: A method of protecting employees from cave-ins, from material that could fall or roll from an excavation face or into an excavation, or from the collapse of adjacent structures. Protective systems include support systems, sloping and benching systems, shield systems, and other systems that provide the necessary protection.
Pre-cast concrete: Concrete members (such as walls, panels, slabs, columns, and beams) which have been formed, cast, and cured before final placement in a structure.

Plaintiff: The party who initiates a lawsuit by filing a complaint with the clerk of the court against the defendant(s).
Polarity: The relationship between poles of positive and negative charge, particularly with regard to wiring of conductors where the ungrounded (hot) conductor and grounded (neutral) conductor form a circuit.
Potential Incident: A condition (such as an unidentified hazard), or an event (such as a near miss), or sequence of events that does not have actual consequences, but that could, under slightly different circumstances, have unwanted consequences.
PPE (Personal Protective Equipment): Protective wearing apparel, when used properly, designed to reduce or eliminate injuries to a worker.
PPM (Parts Per Million): Parts Per Million, a term often used to describe the intensity of a contaminant in an area. Often used in relation to H2S and other gases. Preponderance of the evidence: The greater weight of evidence that persuades a judge or jury to lean to one side as opposed to the other during the course of litigation. In civil trials, evidence is required only by preponderance, not beyond a reasonable doubt. The side with the most persuasive or impressive evidence wins the case.
