Stanford Chemical Storage System

Proper chemical storage is a critical feature of a safe lab environment. Store only compatible chemicals together so that no unintended and potentially dangerous reactions occur. The Stanford Chemical Storage system is based upon the idea of storage groups: groups of chemicals that will not react violently if mixed together. 

Stanford Chemical Storage Groups are built-in for many chemicals in the BioRAFT inventory system.

ANSI Z136.5 and Z136.8 Update

The American National Standard Institute’s (ANSI) Z136 series is the leading set of safety standards regarding the usage of lasers. The most important of these standards to JHU are Z136.5 and Z136.8 which cover the safe use of lasers in educational institutions and research, development, or testing, respectively. This year, both standards have been updated, with the following changes: 

  • Demos and teaching experiments should use visible rather than invisible lasers whenever possible. 
  • All current laser warning signs must be brought up to modern standards. 
  • The Laser Safety Advocate must review all laser demonstration safety plans. 
  • Laser project review forms will now include the following topics: 
    • Recorded room interlock checks to ensure that all entry controls work as expected biennially. 
    • On-the-job training to provide information about best practices to help ensure that all researchers are trained to the same level and that experiments will be repeatable. 
    • Barrier testing – includes details on procedures and other recommended information 
    • A structured self-review process. 
    • Improved risk assessment protocols.

Quality Data for Safer Experiments

It is well understood that, especially in our digital era, proper collection and distribution of data is paramount for good science. This concept is especially important for data concerning safety analysis such as risk assessments and lessons learned reports.  

The following video released by the American Chemical Society (ACS) provides a fantastic introduction to this topic and contributes to our motto that safe science is good science.

Periodic Table of the Elements of Safety

The American Chemical Society (ACS) Division of Chemical Health and Safety has recently partnered with the Princeton University Department of Environmental Health and Safety to publish an updated version of the Periodic Table of the Elements of Safety. 

This interactive table, available to download in various sizes and formats, highlights some of the main hazard categories, risk assessment techniques, PPE, the Hierarchy of Controls, and other interesting information such as Safety Martyrs and Heroes. We encourage you to check out and share this valuable resource.
