Generally speaking, 5-6 things have to go wrong for an incident to occur. Furthermore, these events or failures have to occur in a certain sequence.
The characteristics of mega disasters is that 5-6 events with fairly low probabilities of occurrence line up.

Some common reasons why requirements can cause risk to a project are:
This paper explains how poorly defined requirements can impact the project.
About a year ago, the Minerals Management Services (MMS) proposed a new rule that would require operators of oil and gas operations in the US Outer Continental Shelf to develop and implement Safety and Environmental Management System (SEMS).
It is expected that the rule will be promulgated sometime this year (2010).

On September 15, 2021, ASQ announced the formation of the Center for Electoral Quality and Integrity. This announcement caused a conflicted reaction. On the one hand I liked that the Government Division, which was pushing this action, was showing some level of activity, after almost none for several years. One the other hand, I just laughed at the idea that ASQ and Government Division was going to, or even be capable of, having an impact on electoral quality or integrity. This is not a case of believing the objective is bad.
It is a case of realizing that this is not the 1990s when quality was a key priority of governments around the world. And that ASQ does not have the same level of influence it had, when in the 1990s it was instrumental in getting Education added to the Baldrige Award.
This piece discusses the white paper on Electoral Quality and Integrity which the Center seeks to implement. It also discusses the forces likely to prevent ASQ from being successful.

I noticed that API-14C recommends monitoring of 2-ppm (and higher) SO2 levels. I felt this was a really low threshold value for SO2 .
What surprised me further is that the Immediately Dangerous to Life or Health (IDLH) value for SO2 is 100-ppm…same as H2S!

| Oxygen Concentration (% Volume) | Symptoms of acute exposure |
|---|---|
| 15-19 | May impair coordination. Decreased ability to perform tasks |
| 12-15 | Impaired coordination, perception, and judgment |
| 10-12 | Increased breathing rate, poor coordination and judgment, lips slightly blue |
| 8-10 | Mental failure, fainting, unconsciousness, ashen face, blueness of lips, nausea, upset stomach and vomiting |
| 6-8 | 8 minute exposure: may be fatal in 50-100%; 6 minute exposure: may be fatal in 25-50%; 4-5 minutes exposure: Recovery with treatment |
| 4-6 | Coma in 40-seconds, followed by convulsions, breathing failure, death |

I am pretty close to completing my first book – Agile Enterprise Risk Management, Risk-Based Thinking, Multi-Disciplinary Management and Digital Transformation. It is now at the publishers, awaiting finalization. I have established a site for the book and this is the home page text that describes what AERM is all about.

We all know that air is mostly nitrogen…79% to be precise. What may not be a common knoweldge is that colorless odorless Nitrogen has led to asphyxiation and fatalities and is a risk particularly for personnel working in confined spaces and personnel utilizing breathing air systems.
According to the Chemical Safety Board (CSB) research there were 80 nitrogen asphyxiation fatalities between 1992-2002. This translates to one nitrogen asphyxiation death every seven weeks. Approximately, 10% of fatalities were due to attempts to rescue person in confined spaces.

Teams, they are everywhere; sports teams, project teams, political parties, rock bands, military units, the list goes on. The team isn’t just about the people in the limelight it’s also about the backroom boys and girls who provide logistical, technical, administrative, and sometime moral support to the front men and women. Even the lone competitor or the one-man-band needs some support; everybody needs somebody sometime.

Risk management is an objective-focused concept. Risk professionals must, therefore, be a catalyst, an advocate, and trusted friend for driving superior organisational performance.
They must walk alongside executives, managers and staff to achieve organisational objectives by making better decisions under uncertainty, risk, and opportunities.

While evaluating impact of a toxic release, you may be interested in how the concentration of the toxicant increases in a room and its impact on indoor personnel. For example, if there is a H2S release in the plant and you want to estimate the increase in concentration in a nearby office building.
I want to share a simple model to estimate indoor concentrations following an outdoor toxic release. [Read more…]
New superconducting magnet breaks magnetic field strength records, paving the way for practical, commercial, carbon-free power fusion energy. MIT and U.S. startup company Commonwealth Fusion Systems (CFS) led the project. This test paves the way for a demonstration device to show a plasma can be created and contained that generates more energy than it consumes. The demonstration device is expected to be completed in 2025. The hope is that in the future there will be thousands of fusion plants powering clean electric grids around the world helping to save the planet.
Earlier I had written about the use of RFID for tracking hazardous substances. One of the readers, Sujith, wrote to me that RFID can be a ignition source and thus pose a potential for fire/explosion.
