We are nothing after our death. Let us donate our body organs for the poor.

Be not afraid of anything. You will do marvelous work The moment you fear, you are nobody - Swamy Vivekananda

If you think safety is expensive, try an accident... - O.P.Kharbanda

Preventable accidents, if they are not prevented due to our negligence, it is nothing short of a murder - Dr. Sarvepalli Radha Krishna, 2nd President of India

Zero accidents through zero unsafe behaviors. Do not be complacent that there are no accidents. There may be near miss accidents (NMAs). With luck/chance, somebody escaped knowingly or unknown to the person. But, we can't be safe, if we depend upon the luck.

Safety culture is how the organization behaves when no one is watching.

We make No compromise with respect to Morality, Ethics, or Safety. If a design or work practice is perceived to be unsafe, we do not proceed until the issue is resolved. - Mission statement by S&B Engineers & Consultants Ltd. http://www.sbec.com/safety/

Electrocution

A person died due to electrocution, as reported in a news paper. He received electric shock when he tried to cross a water pool and held nearby signboard rod for support. Due to rain, the signboard is wet. It is not clear why earth fault did not cut off power supply when current was passing through pipe and the water pool below.

Activities that burn your calaries

An article in Times of India on 5th July 2011 is about guidelines of Hyderabad based National Institute of Nutrition (NIN) for changing the lifestyles and help in maintaining better health. Following is the calorie consumption for different activities.
Sleeping, resting, relaxing-1.0 kcal/min
Sitting (light activities like eating, reading, writing, listening and talking)-1.5 kcal/min
Standing (light activities like washing face, shaving, combing, watering plants)-2.3 kcal/min
Walking (slow), driving, dusting, bathing, dressing, marketing, childcare-2.8 kcal/min
Light manual work, sweeping, cleaning utensils, washing clothes, other household chores-3.3 kcal/min
Warm-up and recreational activities, walking up and down the stairs, cycling, fetching water-4.8 kcal/min
Manual work (moderate pace), loading/unloading, walking with load, harvesting, carpentry, plumbing-5.6 kcal/min
High intense manual work and sports activities - tournaments, wood cutting, carrying heavy loads, running and jogging-7.8 kcal/min

From the above, one can calculate energy requirement for their routine. There is an article to find energy requirements in the internet.
Recommendations: Consumption of 300 gm/day of vegetables, 6 gm/day of salt
Use of large amounts or big pieces of food items in microwave oven are discouraged as heating may not be same for entire quantity and cold spots can lead to entry of bacteria into human body. Similarly, cooking frozen food in microwave oven directly is not recommended.
A calorie calculator may be useful for assessing daily needs.

Food calories charts are available here to plan for food intake as per requirement.

Sleep walk, sexsomnia, etc

A news item in Times of India today is about the innocence of a person suffering from sexsomnia. Experts told the court that the person will be telling the truth about his problem. The wife and ex-girl friend too supported the case with similar events in their life with him. Wikipedia has an article on the subject along with diagnosis methods. It is not clear why the person did not go for treatment when ladies in his life already encountered such behaviour and because of continued disorder, a girl has become victim. Letting of people with disorders can create law and order problem as people can misuse. Persons suffering from such disorders should be sent to hospitals for treatment and till it is cured, they should be under supervision.

Similarly, people suffering from sleep walk can create problems to the society by their actions, not known to them consciously. Whether such problems lead to split personalities and pose problem to others is not clear. Hypothetically, if we assume existence of such workers in the workplace, imagine what are the consequences and impact on coworkers and public outside factory premises.

Trench cave-in

The following article appeared in free e-mail news letter of bongrade.com on Wednesday,July 6, 2011, Volume 2, Issue 27. The important points to be noted for any worker in trenches are marked in different colour. One should be grateful for publishers of the news letter. Trench workers can learn a lesson from this and follow good safety practices at their workplace.
-------------------------------------------------------------------------------------------------------------
The sight was enough to make three grown men cry. Their co-worker was chest-deep in mud and only a few inches from death.

Glen D. Rogers of Elsah, IL, said the trench cave-in at his worksite felt like an entire football team had piled on top of him. He couldn’t move and could barely breathe.

“I thought I was going to die…I just wanted to talk to my wife and kids.”

Those were his desperate thoughts as co-workers and firefighters worked feverishly to save him.

Not long before that, Rogers, 34, was busily working in a trench to tap into a sewer line for a new house. He had just cleared off a section of pipe and began walking away when a contractor yelled that the trench was collapsing. Rogers looked behind him and then at his feet, which were buried in mud. Seconds later his legs disappeared, followed by his waist.

At one point, co-workers quickly jammed a couple of boards in the hole to offset the pressure that was crushing Rogers. Both Rogers and his wife believe this is what saved him from certain death.“His co-workers basically saved his life. If they hadn’t done that (with the boards), he would be dead,” said wife Audrey Stewart.

A grateful Stewart said all employees should receive some type of emergency rescue training.

For Rogers, the cave-in fortunately stopped at his chest, but with every breath he took, the dirt acted like a vice tightening around him.Rogers instructed his co-workers to begin a rescue plan by digging a ditch on the other side of the trench he was in. When firefighters arrived, they continued the work.“They dug down to my waist and the blood rushed back into my legs. I thought I had lost my legs because I looked down and they were flat.”

The rescue took about four hours. Luckily, Rogers recovered quickly and was back on light duty a few days later.

Since the ordeal, Rogers and fellow workers have adopted a new sense of job safety by taking nothing for granted and always wearing their safety gear.

“I now find myself green again, being real cautious about where I walk”, Rogers said.

BLEVE explanation with video

The following link gives explanation for BLEVE (Boiling Liquid Expanding Vapor Explosion). The explanatory text below states that BLEVE is possible even with nonflammable liquids which should be noted. Many experts differ with this statement and they talk firmly that BLEVE is possible only with flammable substances. Though, the phenomena is same whether it is with flammable or non-flammable substances, I do not understand why some experts in the field differ about BLEVE with non-flammables. If the substance is flammable, then BLEVE is followed with a fireball, else no fireball. Thermal radiation from fireball can trigger secondary fires (domino) if flammables are present nearby.

Some statements on safety

Following are some of the statements in "Process Safety Analysis - An Introduction"  by Bob Skelton published by Institution of Chemical Engineers, UK.
  1. A good safety culture ensures that both the spirit and the letter of the law are fulfilled.
  2. Attitude to safety should be highly visible and shared at all levels within the company.
  3. A well managed company is almost invariably not only a profitable company but a safe company.
  4. Changes in existing plant are costlier than that introduced in design stage.
  5. Design should be such that operator intervention is not needed for at least 30 minutes after an incident. Experience has shown that operators can not always be relied upon to make the correct decisions under immediate post-accident conditions.
  6. Safety in design must be both proactive and reactive. Changes, once a plant is built, are very expensive compared with changes at the design stage.  It is not sufficient and cost efficient to make safety review after completing the design and then BOLT ON safety devices. It will not be cost effective. Engineered safety is BOLT ON safety. Engineered protective devices can fail and never place too much reliance on BOLT ON safety.
  7. Commissioning is one of the most hazardous parts of any process plant operation. Not only do design errors which escaped previous checks manifest themselves but problems due to construction errors also become obvious. In addition commissioning generates hazards of its own as the plant moves from construction to operating status. It is essential that a formal set of checks be carried out before process fluids are introduced for the the first time.
  8. Fire and explosions can be prevented  by not exceeding 25% of LEL. Flammable atmospheres can be avoided by ensuring that fuel lines and tanks are pressurized so the flammable material leaks out rather than air leaking in. good ventilation of vessels and plant areas can maintain safe working conditions.
  9. Dust explosions are best prevented by good housekeeping - that is, by keeping the concentrations of dust down and perhaps keeping the dust damp. Inerting by dilution with non-combustible dust is another effective technique, frequently used in coal mines.
  10. The risk is serious in case of static electricity, if the relative humidity is below about 60%.
  11. Explosives manufacturing facilities are usually designed so that the buildings are separated by safe distance, surrounded by earth mounds so that any explosion will go upwards rather than affect other plants in the area. In addition there is usually a limit on the number of people allowed in a building.
  12. Fire fighting water causes more damage than the fire itself, when polluted water is let into rivers. There may be a conflict between accepting the atmospheric pollution caused by letting the fire burn out and the water-borne pollution caused by fighting it.
  13. Non-process hazards account more than 70% of all accidents in process plant.
  14. Many of the worst accidents in the process industries are the result of bad maintenance practice. Ex: Piper Alpha and Flixborough
  15. As many people die by asphyxiation as from toxic gases.
  16. A good health and safety policy is always cost effective; most organisations grossly under estimate the cost of accidents, often by an order of magnitude. The organisation should be such that the attitude to safety is highly visible and shared at all levels within the company. Active participation is encouraged to promote the objectives of not just preventing accidents and industrial illness but motivating and empowering everyone to work safely.
  17. A safety culture, once established, must be maintained, any any tendency to careless practices stamped out at once. Experience shows that 80% of accidents tend to happen to 20% of the workforce - the young and the old being particularly vulnerable.  Many accidents are caused by operators not fully appreciating the significance of small, but nevertheless important changes.
  18. A good system of accident reporting is proactive and reactive, whereas most tend to be purely reactive.
  19. Effective safety at all stages of a project - from inception to demolition - can only be achieved if there is a commitment at all levels. The senior management must see health and safety as being just as important as profitability and they must make certain that all their workers are aware of this fact.
  20. A well managed company is almost invariably not only a profitable company but a safe company.
  21. In hazard analysis, a distinction must be made between routine operator action and operator intervention in an emergency.  For routine operator action, the operator can usually take time and is under no great stress. Safety assessments involve the prediction of the likelihood of errors when the operator is taking corrective action against alarms. The time for corrective action may short, the operator is liable to be under some stress and so the probability of errors is greater.
  22. Total elimination of human error will never be possible. Use must be made of the science of ergonomics to ensure that everything possible is done to enhance the strengths of human operators whilst at the same time allowing for the weaknesses.
  23. The most important rule is, 'inherent safety is better than engineered safety', ' what you have not got can not leak'. Even elaborate safety devices can't reduce risk to zero due to the escape of a noxious substance, but replacing a noxious substance by a more benign one could well eliminate that risk altogether.
