Ulocladium

A fungi common on dead plants and cellulosic materials. Ulocladium is found on vegetative made textiles such as cotton.

 

Ultrasonic Cleaning

An immersion process taking contaminated contents and placing them into a solvent with a detergent in a ultrasonic cleaning machine. Education Note Ultrasonic cleaning machines are electronically induced cavitation machines which use sound waves that vibrate contaminates off of a ceramic object to a computer board.

 

Unconditional Waiver and Lien Release

An Unconditional Waiver %u0026 Lien Release document is a legal document which in brief says you as the contractor are waiving all your rights to a property as long as all labor and material payments along with interest charges have been paid. Contractor Note Often this Unconditional Waiver %u0026 Lien Release document becomes required when banks and other financial institutions are making the payments or are signing-off and releasing insurance drafts. In California for example the Unconditional Waiver %u0026 Lien Release is under civil code 3262d4. See Conditional Waiver and Lien Release Liens

 

Uncontrolled Hazardous Waste Site

An area where an accumulation of hazardous waste creates a threat to the health and safety of individuals or the environment or both. Mitigation Note Some uncontrolled hazardous waste sites are found on public lands such as those created by former municipal county or state landfills where illegal or poorly managed waste disposal has taken place. Other uncontrolled hazardous waste sites are found on private property often belonging to generators or former generators of hazardous waste. Examples of such sites include but are not limited to surface impoundments crop and animal farms landfills dumps and tank or drum farms. Special care must be taken in identifying uncontrolled hazardous waste sites. During community-wide flooding where an uncontrolled hazardous waste site has been identified for example a garage where pesticide drums are stored and are in danger of becoming part of a flood the contractor or adjuster must not proceed with containment unless reasonable means of correction can be implemented without exposure to employees and the public. Outside state officials or authorized contractors must be notified and allowed to contain the hazardous material as a waste. See Uncontrolled Release

 

Uncontrolled Release

An uncontrolled release is the accidental release of a hazardous substance from its container. If not contained stopped and removed the release would pose a hazard to the employees in the immediate area or in areas in the path of the release or from its byproducts or its effects such as toxic vapours fire over-pressurization toxic gases or toxic particulates.

 

Underlayment

One of several types of building materials including but not limited to plywood fiberboard press board and particle board that is properly installed over a subfloor before a finish material such as sheet vinyl strip flooring or parquet flooring is installed. Mitigation Note The problem with underlayments is when they become wet saturated they tend to degrade decompose and swell. The finish floor may continue to remain in good condition but if the underlayment is damaged the finished floor often must be removed to repair the damage to the underlayment. Health Note If underlayment is saturated with sewage it must be removed and replaced since it cannot be cleaned and sanitized.

 

Undermining

A process whereby the vertical component of erosion exceeds the base of a building foundation or the level below which the bearing strength of the foundation is compromised.

 

Uniform Building Code UBC

National building codes in which cities and communities must comply with during the initial building construction and restoration. Education Note Flooded buildings which cause or have resulted in structural damage or an impairment of health to its occupants caused by wet building materials. Wet building materials can be a violation of the UBC and other municipal health and safety codes.

 

Unit In Place Costs

The combining of material labour and other elements to form a segment of a building system. See Valuation

 

User

An individual or group involved in the Risk-Based Corrective Action RBC process including insureds and property owners insurance companies and mortgage holders managers and operators regulators attorneys contractors and consultants and other stakeholders.

 

UST

An industry-wide abbreviation for under-ground storage tanks. In the U.S. all USTs must comply with federal state and local regulations. While most of us think USTs are at gas stations many farms businesses and some rural homeowners have USTs. To avoid problems with UST regulations the U.S. Environmental Protection Agency EP has mandated all USTs are to be periodically checked for leaks and corrosion to name a few. Part of the federal requirements can be found in 40 CFR parts 280 and 281. In community-wide flooding for example USTs may become a problem in that they can leak and in some situations empty USTs may detach them self from connections and float to the surface or down stream.
