An atmospheric concentration of any toxic corrosive or asphyxiant substance that poses an immediate threat to life or would cause irreversible or delayed adverse health effects or would interfere with an individual ability to escape from a dangerous atmosphere. Health and Safety Note Any other atmospheric condition that is immediately dangerous to live or health is an immediate hazard that must be avoided. IDLH means any condition that is an immediate or delayed threat to life or that would cause permanent negative health effects or that would interfere with a worker ability to escape or leave a work area without help.

Any cause or condition which water is allowed to collect stand set pool backflow bubble remain brackish and bound or other conditions which do not allow for the movement of water away from a property or building in a relatively short period of time before damage occurs. Improper drainage in water restoration services in wet buildings are those conditions which allow water and humidity to remain trapped or held back.

 

Improper Sewage Clean-up

From sewage backflows into and under buildings after the clean-up and removal of sewage water and effluents improper sewage clean-up is the continued presence of any coliform bacteria.

 

Improper Slope and Grade

Improper slope and grade of a property is that slope and grade which is pitched towards the building. Improper slope and grade results in rain water standing water and sprinkler water to migrate or flow back towards a structure.

 

Improper Water Damage Clean-up

In water damage mitigation after the water from a flood event has been removed and the building appears dry. Improper water damage cleanup is any condition which allows a structure or contents to remain wet or damp resulting in further building and contents damage mold growth or wet environments that result in occupant illness. See Consequential Damage Secondary Damage Sick Buildings

An insurance policy which contractors have that provides equipment content coverage while you are away and in transit from your office or primary base of operation. There are generally two types of valuation methods for claims settlement with an inland marine policy. Replacement Cost RC and Actual Cash Value ACV. Replacement cost is the cost to replace %u0027old%u0027 tools with %u0027new%u0027 tools at their current replacement price without deducting for depreciation. Actual cash value is arrived at by taking the replacement cost and deducting the depreciation brought about by any physical wear and obsolescence when applicable. Replacement cost coverage is generally more expensive than actual cash value.

Insulation

1 Building insulation is typically fiberglass cellulosic materials and sometimes rigid or blown-in urethane foam having an average thermal rating of R-11 R-13 R-19 or R-30. Construction Note Building insulation is found in exterior walls and attics and sometimes under the floor joists of sub-floors. Wall insulation is found in the UBC Codes and meets different ASTM Standards. 2 Building insulation is any other property that provides moisture and thermal protection for a building. Safety and Construction Note Wind driven rains to fog will not enter the building based on its design and engineering. This design and engineering of protecting the building atmosphere cannot take into account indoor water damages. Indoor water damages are considered sealed in a tight buildings insulated envelope having no reasonable method of escape either for the water vapour humidity and condensation. Once building insulation become wet they must be investigated immediately and determined the best method for drying and dehumidification before mould and secondary building damage occur. Refer to the Moisture Control Handbook by Joseph Lstiburek and Restorative Drying by Claude Blackburn See Condensation Dehumidification Drywall Wall Cavities Water Damage
