Soil and rock monitoring programs that use inclinometer probes often run for several years. Normal wear and tear can degrade the probe’s ability to produce useful surveys, though this degradation can happen incrementally and may go unnoticed for some time. A new standard developed by ASTM International Committee D18 on Soil and Rock, D 7299 , Practice for Verifying Performance of a Vertical…

ASTM International, one of the largest voluntary standards development organizations in the world, announced the approval and availability of a new standard for collecting, packaging, and transporting visible powder samples suspected of being biological agents. ASTM E 2458 ,, Standard Practices for Bulk Sample Collection and Swab Sample Collection of Visible Powders Suspected of Being Biological Agents from Nonporous Surfaces, is the first standard to address the subject. E 2458 incorporates reference guidance to comply with appropriate federal regulations regarding biosafety and biosecurity. The standard is applicable to nonporous surfaces only., Cooperative Interagency and Stakeholder Effort, The development of a sample collection standard was initiated by the U.S. Department of Homeland Security (DHS) in order to address the problems associated with haphazard sample collection and screening. DHS assigned the National Institute of Standards and Technology (NIST) to coordinate and lead a task group whose charge was to develop a standard protocol for the collection of powders that are…, ASTM Committee E54 on Homeland Security, Currently there are over 500 stakeholders in Committee E 54 on Homeland Security, representing diverse groups including first responders, manufacturers, suppliers, trade and professional associations, and federal, state and local government. The committee was first organized in 2003. E 2458 is the third standard issued by Committee E54 on Homeland Security, and the first standard of Subcommittee…, Two-Step Procedure, E 2458 is a two-step procedure that is performed after an initial risk assessment is conducted and a visible powder is deemed a credible biological threat. The first step of the procedure, or Method A, covers the bulk collection and packaging of the suspicious visible powders from solid nonporous surfaces. Bulk samples are collected and transported in a manner that permits public health and…, Sample Collection Procedure Proven to Work, A study was conducted in March 2006 to validate the reliability of the sampling procedure at the U.S. Army Dugway Proving Ground. The study demonstrated that the sampling procedure can be used by trained Emergency Responders in simulated emergency conditions to consistently recover samples. The study also proved that sufficient number of Bacillus anthracis spores can be detected by Emergency…, after, all bulk samples have been collected. The evaluation study was designed to determine the recovery efficacy on seven environmental surface types that included stainless steel, food-grade painted wood, rubber, tile, concrete, finished wood, and plastic. The study involved six teams that included four National Guard Civil Support Teams (CST), the Navy’s Chemical Biological Incidence Response Force (…, Contacts, ASTM standards are available from Customer Service (610-832-9585); https://www.astm.org/contact/ ) or the ASTM web site store ( www.astm.org ).
