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

Explosion Hazards of Multicomponent Combustible Gas Mixtures
Apr 2, 2012
Alfonso F. Ibarreta
Laminar and turbulent premixed flame burning velocities are two parameters that are sometimes needed to evaluate explosion hazards. There is ample information in the literature regarding the burning velocities of most common ignitable gases and vapors in air. Little information, however, is...
The CCPS Reactivity Evaluation Software Tool

Edward M. Davis
Incidents involving uncontrolled chemical reactions continue to result in injuries, fatalities and economic loss and harm in industry. These incidents are often the result of not identifying or understanding the chemical reactivity hazards involved in storage, mixing or processing operations. The...
Flammability Limits of HYDROGEN and ITS MIXTURES with Hydrocarbons In AIR AT Atmospheric and SUB-Atmospheric PRESSURES

FLAMMABILITY LIMITS OF HYDROGEN AND ITS MIXTURES WITH HYDROCARBONS IN AIR AT ATMOSPHERIC AND SUB-ATMOSPHERIC PRESSURES Hai Le, Subramanya Nayak, M. Sam Mannan The knowledge of hydrogen flammability characteristics, especially flammability limits, is of particular importance and interest because of...
Understanding Reactive Chemical Incidents
John F. Murphy
In order to avoid incidents involving reactive chemical hazards, it is useful to understand the types of chemicals and types of equipment involved, as well as the root causes of the incidents.
Classifying Reactive Chemicals
M. Sam Mannan, Sanjeev R. Saraf, William J. Rogers
This simple classification scheme can be used to characterize the thermal instability risks posed by reactive chemicals in a process.
Addressing the Hazards of Data Omission from MSDSs
James C. Mulligan
If certain chemicals lack physical hazards data, suppliers must be proactive to keep workers safe. Here’s how to determine dust flammability and reactivity data for inclusion on MSDSs.
Screening Reactive Chemical Hazards
Yen-Shan Liu
Use these tools to identify potentially reactive chemical hazards and avoid the expense of conducting numerous detailed hazard assessments.
Guidelines for Identifying and Mitigating Thermal Hazards of Sustainable Materials
Mar 14, 2011
Delmar R. Morrison
Sustainable materials and technologies (a.k.a. ?Green?) are those that are ?delivered with progressively less negative impact upon the Earth.? Thermal hazards such as self-heating, thermal runaway, fires, and explosions may be associated with a particular sustainable material or process technology...
Kinetic Modeling of the Reactions Involved in the T2 Explosion

Ronald J. Willey
The runaway reaction at the chemical preparation facility called T2 laboratories in Jacksonville, Florida on December 19, 2007 is analyzed. The approached involved estimating kinetic parameters based on temperature time traces presented in the CSB final report for ARSST (Advance Reactive System...
Safety Studies for Reformatsky Chemistry In a Meso-Scale Continuous Process System
Mar 13, 2011
Gabriel Loh
The production of fine chemicals and pharmaceuticals has been traditionally achieved via batch processes. More recently, there has been interest in using multiscale (meso- and micro-) reactors for the production of these fine chemicals and pharmaceuticals. These efforts in process intensification...
