Development and psychometric evaluation of the Research Laboratory Safe Behavior Survey (RLSBS)
Conclusions The newly developed RLSBS is a promising instrument to measure a notable gap in the assessment of safe behaviors in research laboratories. This instrument has the potential for use in identifying unsafe behaviors before accidents, injuries or damages occur. Additionally, this instrument may be used by EH&S professionals to effectively direct training and administrative controls to improve the culture of safety at research institutions.

Remediation of manufactured methamphetamine in clandestine laboratories. A literature review
Publication date: Available online 16 February 2017 Source:Journal of Chemical Health and Safety Author(s): Clyde V. Owens The purpose of the current literature review was to identify, collect, review, and organize all available information concerning clandestine laboratories used to produce methamphetamine through an analysis of routinely collected data sources. There were numerous peer reviewed journals, electronic databases, websites, and commercial vendors relevant to the remediation process of methamphetamine laboratories. Our intention in this review was to produce background information as well as a reference gui...

Accumulation and risk assessment of heavy metal contents in school playgrounds in Port Harcourt Metropolis, Rivers State, Nigeria
This study was carried out to determine the level of heavy metal contamination of school playground soils in Port Harcourt Metropolis. Soil samples were collected from ten (10) different school playgrounds and analyzed for their heavy metal concentrations using an atomic absorption spectrophotometer. The investigation revealed the concentration of heavy metals in this trend; Fe>Zn>Cr>Cu>Co>Pb>Ni>Mn>Cd>As>Hg. The models employed to evaluate the degree of contamination and source of metal pollution; index of geoaccumulation and pollution load, contaminatio...

The efficacy of alkalized liquid hydrogen peroxide for the remediation of manufactured methamphetamine in clandestine laboratories
Publication date: Available online 1 February 2017 Source:Journal of Chemical Health and Safety Author(s): Clyde V. Owens The aim of this study was to evaluate the effectiveness of alkalized liquid hydrogen peroxide (A-LHP) as a “low tech” decontamination option to reduce methamphetamine from non-porous and porous building materials. The A-LHP decontamination solution was generated by adding sodium carbonate (Na2CO3) to 15% hydrogen peroxide (H2O2) until the solution was slightly alkaline with a pH of 8.5. The efficacy of alkalized liquid H2O2 against methamphetamine was initially evaluated in the liquid–liquid si...

Make safety awareness a priority: Use a login software in your research facility
Publication date: Available online 21 January 2017 Source:Journal of Chemical Health and Safety Author(s): F.E. Camino A facility login software, whose objective is to improve safety in multi-user research facilities, is reported. Its most important safety features are: (1) blocks users from entering the lab after being absent for more than a predetermined number of days; (2) gives users a random safety quiz question, which they need to answer satisfactorily in order to use the facility; (3) blocks unauthorized users from using the facility afterhours; and (4) displays the current users in the facility. Besides restrict...

Assessment of shooter's task-based exposure to airborne lead and acidic gas at indoor and outdoor ranges
The objective of this study was to measure the shooters’ task-based personal exposure to total fume, lead, and acidic gasses during two-hour shooting sessions at indoor and outdoor shooting ranges. Both pistols and rifles were used, and about 180 rounds of ammunition were fired per shooting session. Total fume was collected by inhalable and respirable fractions and determined gravimetrically. Airborne lead and acidic gasses were analyzed using an inductively coupled plasma mass spectrometer and an ion chromatograph, respectively. The results indicated that significant amount of aerosol mass was in the respirable fraction...

Rotator cuff strength balance in glovebox workers
This study compared the rotator cuff muscle strength ratios of glovebox workers to the healthy norm. Descriptive statistics were collected using a short questionnaire. Handheld dynamometry was used to quantify the ratio of forces produced for shoulder internal and external rotation. Results showed this population to have shoulder strength ratios significantly different from the healthy norm. Strength ratios were found to be a sound predictor of symptom incidence. The deviation from the normal ratio demonstrates the need for solutions designed to reduce the workload on the rotator cuff musculature in order to improve health...

Using bowtie methodology to support laboratory hazard identification, risk management, and incident analysis
Publication date: Available online 23 November 2016 Source:Journal of Chemical Health and Safety Author(s): Mary Beth Mulcahy, Chris Boylan, Samuella Sigmann, Ralph Stuart Hazard prevention and control systems for specific laboratory processes must be readily shared between lab workers, their colleagues, and lab supervisors. In order for these control systems to be effective in a transferable and sustainable way, effective risk management communication tools must be present. These tools need to be adaptable and sustainable as research processes change in response to evolving scientific needs in discovery based labora...

A software for managing chemical processes in a multi-user laboratory
We report a software for logging chemical processes in a multi-user laboratory, which implements a workflow designed to reduce hazardous situations associated with the disposal of chemicals in incompatible waste containers. The software allows users to perform only those processes displayed in their list of authorized chemical processes and provides the location and label code of waste containers, among other useful information. The software has been used for six years in the cleanroom of the Center for Functional Nanomaterials at Brookhaven National Laboratory and has been an important factor for the excellent safety reco...

A comparison of benzene exposures in maintenance and regular works at Korean petrochemical plants
Publication date: Available online 15 October 2016 Source:Journal of Chemical Health and Safety Author(s): Eun Kyo Chung, Jae Kil Jang, Dong Hee Koh The goal of this study was to compare the exposure levels of benzene in maintenance and regular works at the petrochemical plant. Four companies handling benzene were investigated during maintenance and regular works. The data were analyzed by classifying the workers into two groups (maintenance operations: 129, regular operations: 63) comprising a total of 192 plant workers. Benzene concentrations in long-term samples during maintenance were found to be 1.7–9 times hig...

A software for managing afterhours activities in research user facilities
We present an afterhours activity management program for shared facilities, which handles the processes required for afterhours access (request, approval, extension, etc.). It implements the concept of permitted afterhours activities, which consists of a list of well-defined activities that each user can perform afterhours. The program provides an easy and unambiguous way for users to know which activities they are allowed to perform afterhours. In addition, the program can enhance its safety efficacy by interacting with lab and instrument access control systems commonly present in user facilities. (Source: Journal of Chem...
