Gallon
A unit of liquid measurement. 4 quarts of water equal one gallon. 8 pints equal one gallon. Restorative Drying Note%u003A In using water damage liquid measurements%u002C the total water flow in a building from a broken pipe%u002C is measures in gallons%u002C while dehumidification is measured in pints or grains per pound.

Manufactured ozone machines which are made for deodorization and neutralization of carbon-base odors. a%u0029 Gas-phase ozone generators are used successfully in fire deodorization in building materials and contents. b%u0029 Some manufacturers are reportedly marketing their machines as equipment which is able to remove allergies and other micro-pollutants from indoor air.

General Liability Insurance
The insurance required by all states when registering their contractors. While working at a customer%u0027s premises%u002C a general liability policy will help protect contractors in the event that they become legally responsible for bodily injury or damage to the property of others. General liability insurance coverage is a protection against damages brought against a contractor from their customer or a third party. It protects against damage while the contractor is performing a specific job or task%u002C and in some instances%u002C after the job or task has been completed. General liability insurance is required by most property adjusters when the contractor applies for preferred vendor status. General liability insurance protects the project and provides for other forms of insurance protection. There are three primary aspects of general liability coverage which may be part of your policy or needs to be added as a rider to the policy. 1%u0029 Premises/Operations Coverage%u002C which provides insurance protection while performing a job or task%u002C whether the contractor is at the shop or at the customers location. An example would be someone tripping over your tools and being injured. 2%u0029 Completed Operations Coverage%u002C which provides insurance protection after the contractor has completed a job. An example would be after cleaning or restoring a building and paint discoloration occurred after it dried%u002C because of hidden damage. 3%u0029 Care%u002C Custody or Control Coverage%u002C which provides insurance protection for restoration%u002C repair and replacement of property due to faulty workmanship. This includes the property of others while actually being serviced. %u0028Under the standard general liability insurance policy%u002C damage to the personal property of others in your care%u002C custody or control%u002C is excluded%u0029. This means that if property is damaged while being serviced%u002C there is no protection or insurance coverage under a standard policy. Care%u002C custody or control insurance coverage may be offered only through a special endorsement to the standard policy.

Grains of Moisture
Approximately 7%u002C000 grains of moisture produce one pound of water %u0028Grains per pound GPP%u0029 in one pint of water. Calculation of the specific humidity%u002C grains of moisture GPP in a building%u0027s atmosphere. Restorative Drying Note%u003A Along with psychometric charting and moisture monitoring%u002C the GPP of moisture is another important tool to know to dry out and dehumidify a wet building properly. But do not loose focus on the relative humidity measurements%u002C since the relative humidity indicates how close the ambient air is close to being saturated. It is a better measurement to help the restoration technician. Knowing the specific humidity alone%u002C will not the degree or percentage of saturation.

Gram
a%u0029 A metric unit of weight as noted by the symbol %u0028G or g%u0029. One ounce of a substance equals 28.4 grams or 28.4-G. b%u0029 A doctor named Christian Gram%u002C was the first scientist%u002C using a microscope and staining methods%u002C was able to separate positive and negative bacteria. The staining method is named after Dr. Gram. Bacteria are referred to as being either Gram positive or Gram negative.

Gram-negative Bacteria
Bacteria that do not retain the crystal violet stain in their cells%u002C when stained by the procedure described by Doctor Gram%u002C and the bacteria appear pink or red when viewed under the light microscope. Education Note%u003A Most Gram-negative bacteria are bacteria that are enteric and are associated with the excrement from humans and animals. Gram-negative bacteria include Escherichia coli %u0028E. coli%u0029%u002C Klebsiella%u002C Enterobacter%u002C Citrobacter%u002C Proteus%u002C Streptococcus%u002C Shigella%u002C Salmonella%u002C Clostridia%u002C Serratia%u002C and Pseudomonas species%u002C to name a few bacterial pathogens. Health Note%u003A Most Gram-negative bacteria possess complex lipopolysaccharides in their cell walls. These substances can produce endotoxins%u002C which are harmful to humans when ingested or inhaled. All disease causing pathogens thriving in a living or working environment are unacceptable and are considered unhealthy%u002C especially when the building was effected by a sewage contamination. Mitigation Note%u003A The complex cell wall of a Gram-negative bacteria consist of a double cell wall which easily does not break down without some help through mechanical scrubbing and detergents with hot water. In other words%u002C the cleanup of Gram-negative bacteria requires aggressive cleaning and sanitizing methods to be successful.
