Samples personnel

When testing and analysis are completed, the data can be analyzed and summarized. Statistical methods are often used during this step In a study. Data should first be edited and validated. Quality assurance Information from both the sampling and laboratory analyses should be considered In this validation. Field sampling personnel and laboratory scientists should maintain responsibility for data validation. 

Samples of potential chemical interferences were also prepared by placing samples of selected materials inside clean cardboard boxes. The potential inter-ferent items were materials commonly encountered in demining operations such as petrol. These materials were sampled in an identical fashion as the positive samples. Blank samples were also prepared by sampling empty cardboard boxes. All samples were marked by sampling personnel in a manner that made it impossible for analysts to determine the composition of the sample during analysis. Nomadics personnel and dog handlers were not given any information on sample identity until analysis of samples was completed and results were submitted for scoring (i.e., the tests were conducted in a blind fashion). 

The supplies and equipment for surface water sampling varies depending on the type of the body of water to be sampled and on the intended use of the data. If sampling personnel is planning on entering the water, personal protection, such as rubber boots... 

Sample Custodians open the coolers, remove the COC Forms and verify the COC Form against the cooler contents. At many laboratories, Sample Custodians will not sign and date the COC Form and log-in a sample into the LIMS until all identified discrepancies have been resolved with the client. The resolution of outstanding issues may delay the start of analysis and erode the sample holding time. The following mistakes made by field sampling personnel are detected at this first step of the laboratory process ... 

Although sampling personnel will attempt to collect homogeneous samples, the Contractor shall examine each sample and determine if the sample needs phase separation or mixing. The extent to which phase separation or mixing is required will depend on the sample type. 

For most types of contamination detected, there are usually many possible sources, not the least of which are the sampling personnel, equipment, and lab processing and... 

Steps must be taken to prevent personnel from coming into contact with white phosphorus and white phosphorus munitions. The hazards posed to sampling personnel from white phosphorus included the potential for fire and explosion, and the inhalation of toxic fumes produced during its burning. 

All hazards and risks involved in field sampling should be identified and documented in the sampling protocols. In addition, sampling personnel should be briefed concerning the hazards and appropriate safety procedures. Where necessary, protective equipment should be available. 

Are hazards associated with sampling sites and equipment/materials identified and are appropriate measures in place to protect the health and safety of sampling personnel ... 

Contingency plans to be used in responding to a potential emergency should be prepared prior to any sampling activity. Sampling personnel should use appropriate personal protective equipment (PPE). Coordination with local response agencies is recommended. 

Verification—The sampling personnel should be able to verify that the sample vessel was filled as planned. This can be accomplished by several methods.
