How to dispose a sample after testing as per NABL-ISO-IEC 17025:2017



 The sampler shall endorse the relevant records of complete Assortment/ Batch/ shipment/ consignment/ Lot as the case may be, maintained at the place of sampling.

The laboratory is liable to maintain confidentiality of samples and information thereof.

The laboratory shall keep the remnants of the sample after testing for a minimum period of three months and reference sample for a period of six months in stipulated storage conditions before they are disposed off or returned to the customer. In case of samples tested for Biological parameters the sample shall be retained for reasonable period as per lab’s policy based on importing country’s requirement. The mode of disposal of sample after test shall be recorded and indicated in the test request as well.

The testing under the scope for approval shall be in compliance to the methods of validation as per the requirements of the importing countries if any.

The Laboratory shall be audited for the harmonized methods of sampling, sample preparation and analysis purpose being followed as per applied scope.

Details of sampling and analysis charges for each product shall also be submitted together with application by the applicant laboratory.

The laboratory shall be subjected to verification audit (informed in advance /uninformed depending upon the nature of complaint) in case of any complaints in sampling, testing and test reports or any other reasons.

Disposal

Radioactive Solid Waste - Radioactive solid waste shall be disposed at a facility licensed by the regulatory state for such disposal, another agreement state, or the NRC.

Radioactive Liquid Waste - Certain water-soluble liquid wastes may be disposed of by release into sanitary sewage systems in accordance with the laboratory’s radioactive material license. Sewage disposal is commonly used for low-level radioactive liquid waste (usually in the form of pH-neutralized waste) as long as it is readily soluble in water and meets requirements.

FIRE SAFETY

  Fire safety is the set of practices intended to reduce the destruction caused by Fire. It includes those that are intended to prevent ignition of an uncontrolled fire, and those that are used to limit the development and effects of a fire after it starts. All of our work forces are trained to handle all fire fighting equipments and thus in case of emergency they need not depend on fire brigade to extinguish the fire to avoid destruction.   The fire is a common and serious emergency situation that security has to deal with. As a security guard, your main duty is to protect people and property but the fire can destroy both in a minute. You should manage and look over the fire hazard on your site. Mostly, the security guards are the first person to detect in the early stage of fire. In the case of fire, you have to know how to react quickly and confidently. So, you should know the available types of fire equipment and their location on your site. Not only this but also...

How to calculate combined uncertainty for NABL/ISO/IEC 17025:2017

Image
To calculate the uncertainty of your measurements, you'll need to find the best estimate of your measurement  and consider the results when you add or subtract the measurement of uncertainty. After measuring the individual uncertainty due to type A and type B, the combined uncertainty (U c ) is calculated as follows; U c  = √ (U 1 2  + U 1 2  + U 1 2 +……) Where; U 1,  U 2,  U 3  etc are uncertainties calculated with same units        Another method of combining uncertainty with different units of measure is fractional uncertainty. 1.      Identify the equation 2.      Calculate the fractional uncertainty for each contributor 3.      Calculate the combined uncertainty 4.      Convert the result to the desired unit of measure. The quantities that affects the measurand may not have a direct one to one relationship with it. Ind...
