Terrorism Risk Insurance Act Exclusions: Gray Coverage Areas

Terrorism Risk Insurance Act Exclusions: Gray Coverage Areas

The U.S. Government has extended the Terrorism Risk Insurance Act (TRIA) to 2014. TRIA is intended to support insurance companies in case the claims from a terror incident go above a certain threshold.

What is interesting are the exclusions used by the government for this reinsurance.

A Proposed Classification For Reactive Chemicals

A Proposed Classification For Reactive Chemicals

The reactivity of a chemical or a mixture is normally assessed by thermal analysis. Thus the thermal analysis data forms the basis of risk mitigation decisions. What does the thermal analysis data tell us and how to base risk mitigation decisions? How to tell which compositions are more reactive and should be scrutinized closely?

Missing from the current body of knowledge is a simple classification to help rank compositions in order of their reactivity.

Preventing Pipeline Ruptures

Preventing Pipeline Ruptures

The major cause of natural gas pipeline rupture is not corrosion or material defect but external damage.

External damage is the damage to pipeline during digging, pilling, ground work, etc. by heavy equipment such as anchor, bulldozer, excavator, or plough.  Moreover typically the external damage is from third party construction activities and not the pipeline owner-operator.

Industrial Safety In Slumdog Millionaire Nation

Industrial Safety In Slumdog Millionaire Nation

According to the International Labor Organization (ILO), there were 11 deaths every 100,000 workers in India in 2005. This number was two in the US and 0.01 in Japan. What is scary is that the number of fatalities may be significantly underestimated because of absence of a formal accident tracking system. I suspect the situation in other developing nations isn’t significantly different.

Why is the fatality rate in the industrial sectors in the developing nations so high?

Systematic Evaluation Of Reactive Chemical Hazards

Systematic Evaluation Of Reactive Chemical Hazards

Evaluation of reactive chemical hazards can range from simple paper-based calculations to highly complex testing and modeling. This post is aimed at helping you formulate a systematic strategy for evaluating reactive chemical hazards in your facility.  I will divide the various approaches in three tiers – simple to complex.

Equipment Failure Modes

Equipment Failure Modes

An existing equipment in a refinery may display flaws/damages that either existed during manufacturing or were induced during service. Let us briefly look at pre-service flaws and service-induced deterioration.

Group Additivity Approach For Estimating Reactive Hazards

Group Additivity Approach For Estimating Reactive Hazards

During process development or plant operation it is often necessary to estimate energy of reaction based on chemical formulae representation alone. This heat of decomposition represents the potential energy that can be released and is therefore a measure of explosion potential. One can therefore envision that estimation of heats reaction based on chemical similarities should be possible similar to Benson’s group additivity for estimating heats of formation.

Regulating Reactive Chemicals

Regulating Reactive Chemicals

Recently, members of  Congress sent a letter to OSHA chief, Jordan Barab, to expand PSM standard to address reactive chemicals.

Reactive chemicals have gained increasing attention since the Chemical Safety Board (CSB) released its report on reactive chemicals in 2002. Now I have been working in the area of reactive chemicals since 1999 and let me assure you that one cannot say let us regulate chemical A because it is a reactive chemical.

What Is Inherent Safety?

What Is Inherent Safety?

A process is described as inherently safer if it reduces or eliminates one or more process hazards and this reduction or elimination is accomplished through changes that are permanent and inseparable.Below are strategies for achieving inherent safety:

Dust Explosion: Size Does Matter

Dust Explosion: Size Does Matter

We have been burning wood since days of the caveman. But did you know that wood can also explode?

Logs of wood will not explode but fine dust can lead to a fire and explosion. Let us see why.
