Ego - obstacle to safe practices

Generally, safety professionals have advisory role. Any advise from company's safety professional(s) may be taken with good heart, reluctantly accepted because of pressure from top management or will be rejected vehemently. Sometimes, safety professionals will be questioned about their knowledge/experience/capability in matters of production activities and production managers try to draw a line saying that they are more capable of taking care of their work and also of safety in their work place and that they do not need any advise from safety professionals.
However, when some incident happens, safety professional of the company will become the first target of these production managers, saying that they were not sufficiently warned about the hazard, that the safety professional slept without doing his job, and so on. This will be the case even if there were some incidents in the work place.
Surprisingly, sometimes, even regulators too question safety professionals of the company instead of engaging the production managers for safety related lapses in the work place.
The ego in the minds of production managers (and down below) is an obstacle to listen to the voice of safety professional and this endangers safety of employees in the work place. They do not accept the fact that there is something (mindset to see the dangers and to learn lessons from events) missing on their part leading to occurrence of nearmisses, incidents and accidents. Any occurrence is taken as onetime affair and is not acknowledged for system deficiencies. Even efforts will be made to cover up the issues or not to bring to the notice of safety professional for investigation and thus do not want to learn lessons.
The case studies, lessons from occurrence that are freely available in the internet are taken as too theoretical or that these are not applicable to their work place. Nobody can help such managers and those working under them will only become easy prey to the hidden dangers.

Manage Change before it manages you

I read above quotation somewhere and noted in a pocket diary. Today, while going through the book I found this again.
Many changes take place everywhere and we carry out those changes most of the times to meet immediate requirement rather than analyzing for hidden dangers (or side effects). My colleague's brother who was a scientist during his government service used to say, 'what is temporary today is permanent'.
Safety professionals will be facing problems in convincing the shop floor managers to carryout proper hazard analysis and many times, the reply will be that they need clearance to execute so and so job and later it will be removed or it will be taken up for study.
There were a number of examples listed by reputed safety professional Trevor Kletz in his books like, What Went Wrong, Still Going Wrong, Learning from Disasters, etc, where many incidents took place because of improper or no evaluation of hazards.  Management of change is an important aspect in industries without which, we may end up with unforeseen events.
Sometimes, even shop floor workers too will find safety department an obstacle to their production job because of questions raised on safety, though, if something wrong occurs, it is the safety professional who will be questioned for not being authoritative or not active.
Hence, whatever be the nature of change or modification proposed, let it be process parameters, raw materials, equipment, or its accessories, auxiliary services, supports, or even operators, one should carry out a detailed analysis for hazards, impact on operation due to lack of knowledge/training/behavior, etc and then only proceed if satisfied with the results.

Dead teach the living - A study on delayed effects of MIC

A study by ICMR on effects of MIC released during 1984 Bhopal accident published in The Hindu states that MIC and its degradation products cause edema and fibrosis. We use thousands of chemicals (more than 5,00,000) and but we know the properties and effects only for few thousands. As the old adage says "reinventing the wheel", for healthy life people are propagating organic farming, avoiding meat, eating fruits, doing simple exercises which our ancestors did in the form physical work at home and fields, walking, cycling and so on.
We need not overreact on knowing about dangers, but one should be careful and be judicious while dealing with any of the chemicals so that we can atleast sustain the environment for future generations.

Dangers of confined spaces - Oxygen levels below 19.5%

I read an excellent article on wrong notions of safe oxygen level of 19.5%. One should find why oxygen levels are below 21% and only after getting satisfactory answer, should venture into confined space with proper PPE. I feel that, once oxygen levels are below 21%, one should go inside only with airline respirator / self contained breathing apparatus as suitable it is. We should remember that catridge/canister type respirators are useful only upto 2% of contaminant concentrations and above this, one should use fresh air supply system.
