Pack-Out

An insurance term typically meaning the methods requiring inventory boxing removal and temporary storage of contents from a damaged property. Education Note Some pack-outs are provided by office relocation companies whose job requires the removal and relocation of contents and equipment to temporary facilities until the damaged property can be restored back to pre-loss conditions. The pack-out in part is necessary to reduce business interruption. Other pack-outs are provided by a specialty contractor who is involved in fire damage restoration. In this situation the pack-out requires the contents to be removed cleaned and restored back to pre-loss conditions before they are returned to a restored property. See Business Interruption Coverage

PAPR Positive Air Pressure Respirators

Full-Face respirators which are positive air pressure fed from filtering canisters and a motor. The filtering canisters motor and battery are on a belt worn around the waist. The supply hose comes from the filter housing to the full-face mask. PAPR respirators are the preferred respirator required for certain contaminates and confined space work where heat-stress is a factor when working in Level-C or B PPE. Safety and Health Note PAPR respirators are only efficient if the appropriate filter canisters are in place%u0021 As a general filter canister rule consider using HEPA/Organic/Acid Gas-type filters. OSHA Note The contractor must provide the right filters relative to the contaminates involved. For H2S and SO2 only in-line air or SCBA can be used because H2S and SO2 elements are gases and filter canisters cannot screen out these gases. OSHA Note All atmospheres where flammable explosive air gases vapours mists and toxins are present or are suspected or the atmosphere may not contain appropriate breathable air or because of the work involved an employee may create an atmospheric hazard exceeding PM-10/50 proper monitoring and engineering controls must be implemented before employees can work in a hazardous environment.

 

Particulate Matter

A solid material that is a byproduct of construction waste which easily becomes airborne and can be inhaled. An airborne dust spore pollen or bioaerosol which can result in asthma and allergy-like conditions when inhaled. c A solid material that settled out of air which can easily become airborne through disturbance or increased air movement. d Particulate matter in water especially contaminated water while it is in a dissolved state. e When surface water is removed particulate matter constitutes the insoluble sand clay fines and other solid matter after an outdoor flood indoors or a blackwater sewage contamination from main-line sewer backflows. The former U.S. Surgeon General C. Everett Koop warns that every day the average persons respiratory system receives more than two table spoons of particulate matter dust pollen tar rubber acids metals smoke clutch and brake materials bacteria mould and many other hazardous and allergic matter.

 

Pathogens

Pathogens Disease causing microorganisms. Microorganisms including but not limited to viruses bacteria and fungi which have the capacity to cause disease under certain conditions. See Allergens

 

Patina

A natural aging process which over time allows oxidization and weathering to cover some finishes. Caution Note Disturbing the patina through cleaning and sanitizing of some building materials and contents may result in a permanent colour change and even damage to that material. Patina is common on brass and bronze statues sculpture paintings and porcelain. Patina may also be present on artifacts antiques and collectibles. The loss of patina can dramatically reduce the worth value of a particular item. See Diminished Property Value

 

Pattern Matching

Pattern Scribing

In flooring a method of fitting flooring material in small or complicated areas using scribing felt or some other paper that outlines the room and objects that are impeeding a continuous flat-lay of a material. Refer to Armstrong Guaranteed Installation Systems Handbook 2000/2001 @ 800/233-3823

 

Peeling

In paint film terminology peeling refers to the delamination from the substrate or previous coat of paint that represents larger paint film pieces instead of paint flakes. In many instances peeling is due to trapped moisture found behind the painted surface. Also lack of surface preparation painting over salts mildew dirt oily surface chalking or over multiple layers of dried paint film will cause peeling.

 

Peer Review

Perambulate

A word that is not in much use today to describe a site assessment and inspection. To perambulate you are walking around while examining and inspecting the perimeter of a building or property or walking through a large building while taking notes.

 

Perboric Acid

An acid used by itself or it may be found in some cleaning chemicals and powders. Education Note Perboric acid HBO3 forms salts called the perborates which when released in water produces a type of hydrogen peroxide. Perboric acid in water are short lived and to maintain their strength they must be used within a reasonable period of time. Sodium perborates are used in spotters and browning treatments and they produce a mild oxidizing effect.

 

Perceived Risk

A perception about potential risk by employees of their work environment. Safety and Health Note Perceived risks are most often unknown risks and they are recognized through mental awareness a heightened level of sensitivity an insight a sixth-sense or a mental observation about a particular circumstance we find ourselves in which we recognize as to be unsafe. Perceived risk are any potential risk that may be present during the assessment phase and including the demolition or the cleanup phase of a damaged building. OSHA Note OSHA considers all perceived risks to be real risks until they can be proven otherwise. The mitigation employee and their employer must take all appropriate safety corrective action including the use of PPE in protecting employees when there is a perception pertaining to a perceived risk.

 

Performance Bond

An insurance bond taken out by the contractor which protects and indemnifies the building owner in that the contractor will preform and meet all terms within the agreement or the building owner can seek redress by acting and invoking the bond once the contractor fails to preform as stipulated in the contract.

 

Performance Humidity Curve

A temperature and humidity graph depicting the performance of humidity from a water damage while in a buildings atmosphere. Restorative Drying Note The performance curve of humidity as vapor pressure in a building during dehumidification will most likely be different than the trapped humidity vapour pressure located inside wet wall cavities. Monitoring the performance humidity curve is a critical component in managing wet building drying. See Ambient Humidity Permeability Factor Relative Humidity Specific Humidity Thermalgraphic Chart Recorders/Sensors

 

Pergo Flooring

A manufactured floating floor system that has the appearance of hardwood flooring. Pergo is a product trade name owned by Perstop Flooring Inc. Pergo flooring consists of a wood-base core and it is made of wood chips sawdust and adhesive binders compressed under high heat and pressure. The wood material is then applied with a photo-generated picture and it has a wear layer consisting of a melamine plastic finish. Restorative Drying Note The Pergo flooring system has either a five year or seven year product warrantee. Any water damage to the floor may void manufacturer warrantee. If water gets under a Pergo floor system product dehumidification drying may be of little use or benefit but in general the wood chip saw dust binder and floor adhesive on the product including the underlayment are known to weaken and break down often resulting in permanent damage to the effected floor area. For manufacturer information call 800/337-3746. Installation Note All Pergo floor products must have a 6-mil or greater plastic vapour barrier when Pergo products are installed over concrete having less than 5 pounds of vapour pressure per thousand square foot or less than 10%u0025 moisture content of wood subfloors installed with a Pergo SoundblockTM or WhisperwalkTM underlayment.

Permeability

The ease with which water and moisture chemicals gases and toxins are able to move or migrate into out-of and through porous building materials at a molecular level.

 

Permeability Factor

In water damage mitigation permeability factor is the ability of moisture as a vapour along with vapour pressure exerting its energy to penetrate into a material by diffusion.

 

Permissible Exposure Limit PEL

An employee allowable workplace exposure limit to a chemical or biological agent. Health and Safety Note The published permissible exposure levels in which an exposure inhalation or dermal permissible exposure limit exceeds acceptable standards and levels. Employer Note For employees in their workplace it means concentrations of chemicals and agents that must not be exceeded during an 8-hour work shift of a 40-hour work week. There are no PEL levels for persons in non-working environments such as in home unless the home is the designated work facility for a maid gardener plumber or a contractor for example. Also there are no lower limit exposure levels for employees having extreme low tolerance levels to chemicals pollutants and other agents. In California and in other states and the federal register The exposure inhalation or dermal permissible exposure limit specified for California employees are in 8 CCR Chapter 4 Subchapter 7 Groups 14 and 15 and Group 16 Articles 107 109 and 110.

This is considered by CDC hospitals health departments and doctors as being the number one method for preventing the spread of disease. The personal care mandated by an employer to an employee in keeping personally clean and tidy at all times while on a job. c During a contamination clean-up job personal hygiene is the safe level of decontamination of the employee and their equipment necessary to be considered safe and decontaminated.

 

Personal Liability

In insurance terminology personal liability are those damages which an insured becomes legally liable for or obliged to pay because of bodily injury or property damage resulting from an occurrence to which insurance coverage applies. Education Note At the insurer expense and with attorneys of their choice the insurer will defend an insured against any covered claim or suit. The insurer is not obligated to pay defense costs including attorneys fees of any claim or suit where the insured selects an attorney not chosen by the insurer because there is a dispute between the insurer and insured over coverage. The insurer may elect to investigate and settle any claim or suit which the insurer considers proper. The insurer obligation to defend any claim or suit ends once the insurer has paid their limit of liability.

 

Personal Protective Equipment PPE

Company provided repaired and replaced but employee maintained personal safety and health equipment. 29 CFR 1910.132. Contractor Note Equipment which is necessary %u005Bunder OSHA mandates%u005D to provide the level of safety and protection for employees during assessment and mitigation phases of a disaster exposure or hazard. 29 CFR 1910.132 41 CFR 50-204-7. See OSHA Serious Violation

The term petroleum product includes petroleum-based substances comprised of a complex blend of hydrocarbons derived from crude oil.

 

Phase 1 IAQ Assessment/Audit

An indoor air quality IAQ assessment is an IAQ audit-survey of a building and its occupants. This audit by management or a professional who will take into account the history of the building engineering controls to keep it operating safely HVAC system design prior building usage occupancy loads and design. See Environmental Audit Environmental Assessment

 

Phase 1 IAQ Preliminary Building Assessment

A visual fact gathering by management of indoor air quality problems. No professional consulting is required but depending on the issues and fact gathering findings a professional may need to be consulted. If the concerns or problems are obvious there should be immediate resolution of the problem by management.

 

Phase 2 IAQ Sampling with Analysis

The use of ASHRAE standards and suggested EPA recommendations along with indoor air quality sampling. Sampling may include real-time monitoring and sampling for a laboratory. Testing will include thermal conditions temperature and humidity monitoring. Building material deterioration assessment air flow measurements carbon monoxide/dioxide microbiological and VOCs studies are of primary interest to the IAQ/IEQ professional.

 

Phase 3 IAQ Mitigation

Once all the building issues have been evaluated by the IAQ team immediate problem solving should begin. This often requires the removal of the contaminated sources followed with cleaning and sanitization. The ventilation system may require cleaning and sanitization replacement of some insulation and filter media.

 

Phase 4 IAQ Diagnosis

If Phase III is not completely satisfactory then a reassessment of the building and occupant concerns is necessary. Additional testing about other issues are important to state what are the remaining issues%u003F Once old and new problems have been identified and isolated mitigation should again be completed with follow up analysis.

 

Phase 5 IAQ Post-Monitoring and Recurrence Prevention

Depending on the issues such as with flooded buildings it is prudent to recognize that some building concerns may reoccur months later especially when bacteria and fungi were present during the initial cleanup. Change in seasons temperature humidity and time may alter the buildings atmosphere and ecosystem. Post-sampling 6 months and a year later adds to closure of a previously flooded building.

The use of high-pressure water to position pilings in sandy soil by forcing the sand away from the pile-driving direction.

 

Pink-Eye

Also known as Red-Eye which is an inflammation of the eye causing redness discomfort and sometimes a discharge from the affected eye. Health Note Pink-Eye and Red-Eye can be an occupational caused disease from contact with contaminated materials. Pink-eye and red-eye are more commonly referred to as Conjunctivitis. Most conjunctival infections are caused by bacteria for example staphylococci that are spread hand-to-mouth contact with a contaminated surface or where sewage affected pollutants become airborne. Education Note Water damage technicians must wear proper clothing respiratory and eye protection during sewage cleanup. Besides sewage bacteria conjunctivitis can also be caused from airborne dust spores and allergens. c Technicians must eliminate the use of air movers during the cleanup phase especially during mold and sewage damage cleanup or when there is airborne debris created from increased air movement. See Conjunctivitis

Materials included in pneumoconiosis diseases are silica sand dust from air blasting sanding and stone cutting fine fly ash dust or coal dust. A condition of the respiratory tract due to inhalation of dust that are deposited and retained in the lungs resulting in signs and symptoms of a pulmonary disease called pneumoconiosis.

 

Pneumonia

Inflammation of the lungs due to infection. Most cases of pneumonia involve inhalation of a virus or bacteria including Streptococcus pneumoniae and Staphylococcus aureus. Education and Health Note Both bacteria of Streptococcus pneumoniae and Staphylococcus aureus are associated with dirty outdoor and indoor building environments. Buildings that have experienced a sewage contamination and aerosolization of bacteria spores are susceptible to the Streptococcus pneumoniae and Staphylococcus aureus exposures. Staph and Strep bacteria can thrive on organic dust. Pneumonia is also associated with the bacteria Legionella pneumonphilia Legionnaires disease. c During the mitigation of sewage in a building and the cleaning of dirty ventilation systems technicians must wear proper protective clothing and respiratory protection.

 

Pneumonitis

Pollution Liability Insurance Coverage

A coverage that usually protects the contractor from liability and damages resulting from a pollution occurrence. Most general liability policies exclude pollution coverage. However depending on the policy language limited pollution coverage may apply. Pollution insurance may be necessary when contractors come in contact with lead-base paint asbestos contaminated soil liquids and solvents mold sewage biohazards toxins or when contractors use or apply chemicals such as cleaners disinfectants and deodorizers. See General Liability Insurance Policy

 

Poly

An abbreviation for polyethylene sheeting. In the asbestos abatement and mold remediation industry %u0027poly%u0027 is usually referred to as polyethylene or plastic sheeting that covers seals masks protects an environment or contents. In asbestos and mold remediation poly must be 6mm thick plastic sheeting or bags for contaminated material containment. In some areas poly that is used as a barrier of a room for example must be 6mm thick and FR or fire retardant rated.

 

Polyamide Sweat

A painting condition resulting from too cool or too damp of a surface to be painted. Education Note Polyamide sweat causes a yellow appearance in epoxies either as blotches or uniformity of color. With epoxies the sweat condition can occur when the paint hardeners are not mixed well enough in proper proportions or they are not allowed to sweat prior to application. A method of correction to remove yellowing includes MEK and wiping or a solution of 41 water/vinegar and wiping. Caution if MEK methyl ethyl ketone is used it must be used appropriately with the proper amount of ventilation and worker protection.

 

Poria incrassata

Poria incrassata is commonly referred to as a building cancer mould. Education Note Poria must be professionally identified and cut out or the building will continue to decay especially when moisture or high humidity is present. This particular fungi is not airborne it is soilborne and it is able to extract water from soil and organic materials where there is sufficient moisture to thrive. Poria travels up through root-like tubes rhizomorphs that it creates. The fungi will travel up the side of concrete steel and wood until it finds a wood material to suck out the life moisture and nutrients. Poria then uses the nutrient source to thrive as it continues to find other building materials including hardwood floors wood studs and joists to decay. Poria will decay normal healthy and dry wood which are not typically attacked by normal wood decaying fungi. Once established in a building Poria can spread throughout a building quickly destroying large sections of flooring and walls typically in several months to a year. Fortunately only a very small percentage of building decay is caused by Poria in the Southwestern part of the United States. Many more reported cases of Poria are in the South and Southeastern U.S.

 

Post

A long upright support set in holes backfilled with cement or compacted backfilled material. Each post usually requires bracing to other posts. Most posts are made of wood.

 

Post-Emergency Response

As in the case of a fire damage a post-emergency response is that portion of the emergency after the fire is out allowing for emergency board-up structure stabilization temporary repair cleanup and deodorization. In hazardous materials management a post emergency response is that portion of an emergency response performed after the immediate threat of a release chemical or material hazard has been stabilized or eliminated and clean-up of the site has begun. If post emergency response is performed by the on-site employer own employees who were part of the initial emergency response post-emergency response is considered to be part of the initial response and not a post-emergency response action. However if a group of an employers own employees separate from the group providing initial response performs the clean-up operation then the separate group of employees would be considered to be performing post-emergency response during a hazardous materials cleanup. c After an earthquake flood fire tornado or other natural disaster a post-emergency response is that action necessary to further protect life and property from secondary and consequential harm.

 

Post-FIRM

For FEMA insurance rating purposes post-FIRM construction means construction or substantial improvement to a structure that started after December 31 1974 or on or after the effective date of the initial FIRM for a community. For FEMA floodplain management purposes post-FIRM construction means structures for which the start of new or substantial improvement construction commences on or after the effective date of a floodplain management regulation adopted by a community.

 

Potable Water

Water which is suitable for human consumption. It has the absence of coliform heavy metals and other contaminates which meets the drinking water standards.

 

potentially Complete Exposure Pathway

A situation with a reasonable likely chance of occurrence in which a person or persons may become directly or indirectly exposed to contaminates and pollutants.

 

Pounds of Moisture Vapour Pressure

In concrete slabs it is the pounds of moisture pressure exuded up and out of concrete in the form of moisture vapor which must not exceed 3 pounds of moisture vapour per thousand square feet of floor space over a 24 hour period. Contractor Note Cured concrete slabs will always vaporize out acceptable moisture in the form of moisture vapor which dissipates in ambient air of less than 3 pounds of moisture vapor pressure. Concrete slabs that exceed 3 pounds of moisture vapour pressure per thousand square feet of floor space over a 24 hour period do not meet manufacturer installation requirements for sheet vinyl and vinyl tile hardwood strip and hardwood parquet flooring materials. Installing these flooring materials in excess of 3 pounds voids manufacturer warrantees of the product. Glue-down carpet and carpet with pad can have acceptable moisture vapor exceeding 3 pounds but acceptance and clarification of this fact must be acquired from each manufacturer.

 

Powdering of Concrete

Unlike the presence of efflorescence powdering of concrete is the result of wearing of the concrete surface through abrasion an incompatible use of chemicals on concrete or concrete which was produced to meet a moisture content level higher than what is present. See Efflorescence

 

Powdering of Finishes

Precursor

In indoor air pollution a material or substance that reacts with temperature or sunlight and/or other compounds to produce new chemical materials and volatile organic compounds that are present in air.

 

Preexisting Conditons

Environmental or construction conditions damage and exposures that are apparent but they have nothing to do with the present damage incident or claim. Education Note Pre-existing conditions in some instances become part of the current mitigation issues since they cannot be separated from the most recent damage incident or claim. See Old Growth

 

Pre-FIRM

For FEMA insurance rating purposes Pre-FIRM construction means construction or substantial improvement to a structure that started on or before 1 January 1985 or before the effective date of the initial FIRM for a community.

Premises/Operations Coverage

Insurance coverage to the contractor provides protection while performing a job or task whether the contractor is at the shop or at the customers location. An example would be someone tripping over your tools and being injured. See General Liability Insurance Coverage

 

Pressure Washing remediation

The equipment most preferred Education Note 1 In the removal of flood water silt and muck in contaminated buildings experiencing catastrophic flooding. Pressure washing should only be used once the amount of contaminated building materials such as drywall insulation and carpet have been removed and disposed. Pressure washing is better when used with warm water and detergents. c Pressure washing main use is the micro-fine removal of solid and saturated waste which has absorbed into and behind salvageable building material framing. Mitigation Note 2 In the removal of sewage solids effluents and bacteria trapped under and inside framing materials low- pressure washing warm water %u005B140-F%u005D and liquid detergent having 60-120 psi is preferred followed by immediate water extraction and turbo-fan drying.

 

Pressurized Smoke and Vapour

A condition brought about during a fire in a building from heat and cooler air or high heat and vapour pressure that compresses during combustion of burning materials. The pressurized smoke and vapour force combusted airborne particles and soot to penetrate the cooler walls and surfaces with large and micro-fine combusted matter.

 

Primary Pollutant

In water damages buildings there may be more than one pollutant concern. The one that most likely caused or causes the larger health concern is considered to be the primary pollutant.

 

Primary Sampling Strategy

An environmental term used by IAQ investigation teams. Primary Sampling Strategy include methods for determine the background of the problem understanding the issues to which they were retained gaining building history and occupant histories. Primary sampling strategy includes fact finding through a visual inspection of the building inside and outside in and under all parts of the building including ventilation system supply and return air coolers and chillers and filters. See Environmental Audit Environmental Assessment Phase-I Secondary Sampling Strategy
