Use Of RFID In Process Safety: Track Hazardous Chemicals And Track Personnel

Use Of RFID In Process Safety: Track Hazardous Chemicals And Track Personnel

RFID stands for Radio-Frequency IDentification. It is a small electronic device that consist of a chip (capable of carrying 2000 bytes of data) and an antenna.

A RFID device provides a unique identifier and serves the same purpose as a bar code on a consumer product or a magnetic strip on the back of a credit card.

Is Safety Training Helpful?

Is Safety Training Helpful?

Workplace Safety training is a big industry…every year companies are spending millions of dollars on training their employees.

I have always doubted the efficacy of repetitive and boring training sessions whether personal or virtual (Will your Refresher Training Work?). What is more surprising is that organizations are increasing their training budget without evaluating efficacy of their training program.

Exploding Concrete

Exploding Concrete

I recently came across a very interesting incident involving foam concrete.

Foam concrete is produced by mechanical mixing of foam prepared in advance with concrete mixture, and not with the help of chemical reactions. At the incident site, two workers were removing steelwork using angle grinders while the foam concrete was settling. There was an explosion injuring the two workers.

Foam concrete produces hydrogen which is highly flammable.

Biodiesel Incidents Trend

Biodiesel Incidents Trend

Based on incident data in biodiesel facilities, I had written that the biodiesel industry in the US is experiencing an incidentevery two-and-a-half months, i.e. approx. 10 weeks.

Here are incidents following my May 2009 blog post on biodiesel incident frequency.

Is Workplace Safety Merely Common Sense?

Is Workplace Safety Merely Common Sense?

Surprisingly, many organization and professionals believe that safety can be achieved by common sense. Here is an excellent article from Kevin Jones’ Safety at Work blog about common sense and safety:

Did Trees Contribute To Buncefield Explosions?

Did Trees Contribute To Buncefield Explosions?

Recently, Erik, a reader of this blog directed me to a video his firm has created that explains the role of trees leading to the Buncefield explosion.

Remember the Buncefield incident occurred in oil storage and transport depot. Thus the fuel involved was liquid hydrocarbon. The most probable outcome of a liquid hydrocarbon release is a fire…so it is conceivable that other circumstances such as amount and duration of release and the semi-confinement provided by surroundings may have lead to flame acceleration and increased explosion overpressures.

History Repeats Itself: Buncefield, Puerto Rico, Jaipur

History Repeats Itself: Buncefield, Puerto Rico, Jaipur

In December 2005, fire and explosion at Buncefield oil storage depot injured 40 people. Overfilling of a fuel storage tank (Tank 912) led to release of unleaded gasoline (petrol) which formed a cloud of flammable vapor that subsequently ignited.

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.
