Chemical Reactivity Hazards

Chemical reactivity hazards still exist even if a plant doesn’t intentionally run chemical reactions. Chemical reactivity hazards can be manifest through: 

  • Materials which become chemically unstable for a variety of reasons,
  • Intended chemical reactions that get out of control for a variety of reasons
  • Unintended chemical reactions that take place due to accidental mixing of chemicals that are normally separate

Inherently Safer Reactor Design for Complex Reactions Based On Calorimetry Studies

Mar 13, 2011
Alba Lucia Pineda
A number of reactive processes of the agrochemical, fine-chemicals and pharmaceutical industries involve thermally unstable and/or toxic reactants, products or intermediates, for which the chemistry, thermochemistry and thermodynamic properties are barely known. They frequently employ multipurpose...

Burn Injury Caused by Mixing Incompatible Chemicals with Sodium Permanganate

Mar 23, 2010
Russell A. Ogle
This paper discusses the investigation of an accident caused by the mixing of incompatible chemicals, a strong oxidizing agent with a reducing agent. The exact mixture and sequence of mixing was unknown, but the materials included an aqueous solution of 40% sodium permanganate (NaMnO4) and possibly...

Assessing the Burning Rate of Solid Oxidizers

Mar 21, 2010
Elizabeth C. Buc
A method for assigning solid oxidizers and products containing oxidizers to an NFPA Class was developed. The method consists of two reaction-to-fire tests: a bench-scale screening test with thirty gram piles and an intermediate-scale fire exposure test with twenty four pounds of material in...

Thermal Stability of Chemicals Based on Kinetics and Vessel Parameters

Mar 21, 2010
Amy Theis
Thermal stability of a chemical mixture or pure material can be evaluated using adiabatic calorimetry. Several calorimetry testing instruments and techniques will be used and compared for a comprehensive evaluation. Results from these tests can be used to determine kinetic parameters which can be...

Explosion Prevention and Mitigation

Apr 30, 2009
Dr. Daniel A. Crowl, Kenneth Bloch, Paul Amyotte
The analysis, prevention, protection and mitigation of fire, explosion, and reactivity hazards continue to be important to the loss prevention community. This session includes papers that identify, characterize, or offer design and operational guidance on fire, explosion and reactivity hazards...

Case Histories and Lessons Learned

Apr 29, 2009
Delmar Morrison, Mark Kaszniak, Scott Davis
Reviews of process safety incidents and near misses provide valuable learning opportunities. Papers dealing with incidents, near misses, and the lessons learned are presented. Please Note : Case Histories and Lessons Learned -- Spring Meeting 2009 includes the following recorded presentations: ·...

Fires, Explosions and Reactive Chemicals

Apr 27, 2009
James VanOmmeren, Lina R. Saenz
The analysis, prevention, protection and mitigation of fire, explosion, and reactivity hazards continue to be important to the loss prevention community. This session contains papers that identify, characterize, or offer design and operational guidance on fire, explosion and reactivity hazards...

A safety data sheet holds a wealth of information that can help you safely and effectively handle chemicals in the lab, at the pilot scale, and on the production floor.

Dow's Chemical Exposure Index Guide, 1st Edition

August, 1998
Dow Chemical developed the Chemical Exposure Index to help its engineers design and operate safer facilities. This seminal guide to rating the relative acute health hazard potential of a chemical release to workers and the neighboring community is available to the chemical process community. The...
