A Glossary of Disaster Restoration Terms

Pack-out is the process of carefully removing and transporting a property’s contents to an off-site facility for cleaning, storage, or restoration after damage. Pack-outs protect belongings during repair work at the property.

The pad is the cushion or underlayment beneath carpet that provides comfort and support. In restoration, pads often need replacement after water or smoke damage due to absorption.

Particles of incomplete combustion (PIC) are tiny residues created when fuel does not burn completely during a fire. PICs can contain toxic substances and contribute to soot, smoke odors, and air pollution.

Pathogens are microorganisms such as bacteria, viruses, or fungi that can cause disease. In restoration, controlling pathogens is crucial during sewage cleanup, biohazard removal, and mold remediation.

Periodic cleaning is scheduled cleaning performed at regular intervals to maintain safe, sanitary, and functional conditions. In restoration, periodic cleaning helps prevent buildup of contaminants or allergens.

Permeability is the ability of a material to allow liquids or gases to pass through it. In restoration, materials with high permeability can absorb water more easily, requiring thorough drying.

Permeance factor is a measurement that describes the rate at which water vapor passes through a material. It helps restoration professionals assess how materials respond to moisture and drying efforts.

To permeate is to pass through or spread throughout a material or space. In water damage restoration, water can permeate porous materials, leading to hidden damage.

Personal protection equipment (PPE) is safety gear such as gloves, masks, respirators, goggles, and suits used to protect workers from hazards. PPE is essential in restoration when handling biohazards, mold, or chemicals.

Plaster is a building material made of lime, gypsum, or cement used to coat walls and ceilings. In restoration, plaster may require repair or replacement after water or fire damage.

A plenum in HVAC is an enclosed space in an HVAC system that distributes or collects air, typically located above ceilings or below floors. In restoration, plenums must be inspected and cleaned if contaminated...

A Pollutant is a substance that contaminates air, water, or surfaces and poses risks to health or the environment. Common pollutants in restoration include smoke particles, mold spores, and chemicals.

Pollution is the introduction of harmful substances into the environment, such as air, water, or soil. In restoration, pollution may result from fire residues, sewage backups, or chemical spills.

Polyvinyl chloride (PVC) is a durable plastic material commonly used in pipes, flooring, and building products. In restoration, PVC can be damaged by high heat or emit toxic fumes during a fire.

Porous describes a material that contains small openings or pores, allowing it to absorb liquids or gases. In restoration, porous materials like carpet, drywall, and upholstery often require special drying or replacement.

Post-conditions are the state of a property after restoration services are completed. Post-conditions should meet safety, health, and structural standards to ensure the property is fully restored.

Potable water is safe and suitable for drinking. In restoration, ensuring potable water is critical after flooding, sewage backups, or contamination events.

Power washing is a cleaning method that uses high-pressure water spray to remove dirt, mold, or residues from surfaces. It is often used in exterior restoration projects.

Preparation is the steps taken to ready a property, equipment, or crew before restoration or mitigation work begins. Proper preparation ensures efficiency, safety, and effective results.

Preparedness is the state of being ready to respond to emergencies or disasters through planning, training, and resources. In restoration, preparedness reduces response time and damage severity.

Pressurized smoke is smoke that has been forced into cracks, cavities, or hidden spaces under pressure during a fire. It often causes widespread, hard-to-detect damage requiring thorough restoration.

Prevention refers to actions taken to reduce the likelihood of damage, hazards, or health risks before they occur. In restoration, prevention strategies include moisture control, fire safety measures, and regular maintenance.

A professional inspection is an evaluation conducted by a trained expert to assess property conditions, identify damage, and recommend corrective actions. In restoration, professional inspections ensure accurate assessments and effective planning.

A property defect is a flaw, weakness, or damage in a building that reduces its safety, function, or value. Property defects discovered during restoration may require repair to meet code or safety standards.

A protein fire is a type of fire caused by burning protein-based substances, such as food, meat, or grease, which produces strong odors and hard-to-clean residues. Protein fires often require specialized deodorization and cleaning.

A puff back is a release of soot and smoke from a malfunctioning furnace or boiler that can spread residue throughout a building. Puff backs create extensive cleaning challenges and require professional restoration.
