Last week, there was water drip in the bedroom from the indoor unit of split AC. I went to the outdoor unit located on the chajja (sun shade) outside in the balcony, suspecting water pipe choke. I found that somebody put the water pipe in vertical position and is above its elevation in the indoor unit. This chajja is accessible to anyone on the stairs of the apartment complex. While trying to put it horizontal on the window chajja by standing on the stairs floor and bending, I nearly lost balance.
I got doubt what should be the height of the guard rail and a search in internet and factory legislations mention

Competitive world - Stress on safe production
In his address to the National Governors' Association, President of USA said,
And a US trade report states about increased US exports to India and Indian investment in US and the need for more responsibility by the emerging economies like India, China, etc towards global economic growth.
The message lays stress on competition.
"We now live in a world that's more connected and more competitive than ever before. When each of you tries to bring new jobs and industries to your state, you're not just competing with each other but you're competing with China, you're competing with India, you're competing with Brazil, you're competing with countries all around the world". |

Wrong signals - a nearmiss experience
Yesterday, I went to see my friend staying about 20 km from my residence. I went on a 2-wheeler and stopped at a traffic signal. A car was on my right with right indicator blinking. When the traffic signal turned green, I moved straight and this car on my right instead of going straight or right turned left. I was just ahead of it and would have fell down had the left moving car bumped my vehicle. My heart pounded fast for few minutes.
A similar incident happened earlier few months ago which I mentioned in my earlier post wherein I was hit by a car and I fell on the road. Few years ago, when I was going to my office, again, I had a near miss, this time from another 2-wheeler with wrong signals. I was going straight and the scooter with left indicator ON, moved right. The driver shouted at me and when I pointed him to his left indicator, he laughed and drove off.
This type of driving with wrong signals is very dangerous and we have to be careful on the road, more so at junctions, irrespective of the indicators on the other vehicles.

Distraction during work
An article mentions about distractions and interruptions at work arising out of phone calls, visitors, etc and its impact on time to get back to work with same concentration. It says that on average, everyday a desk worker loses 2.1 hrs. Apart from colleagues in the same department, there will be visits by some unexpected visitors without notice which one has to give some time. Then there are some who keep talking on phone. You may want something, but

Population growth - impact on environment and safety
A report says that by the year 2050, our planet will have 9 billion people from 7 billion this year. As many experts says, increase in population will put pressure on scarce resources, environment damage, unemployment and so on. The report says that income will increase and this could lead to more consumption and stresses on finding better methods to produce as at present 7-8 pounds of grains are required for 1 pound of meat and 3-4 pounds for 1 pound cheese or eggs. This may be an indication to have vegetarian food instead of meat products but I do not know whether a person's needs are matched with equal quantity of either grains or meat.

Fall of persons and objects
A news item mentions about suicidal death of a young lady software engineer by jumping from the 4th floor of a multilevel car parking building. What is stunning is the injury to a contract labourer as the lady fell on him during the jump.
This reminds me of an incident heard from my colleague in which a snake held by a bird flying in the sky slipped and fell on a person on the road and the person died due to snake bite.
The reasons for accidents are generally attributed to as 88% from unsafe acts, 10% from unsafe conditions and 2% from others. This type of accidents i.e injury to contractor worker or death of person on the road due to snake bite come under this 2% category.
Though we say all accidents can be prevented, it is difficult to imagine what can be done in these situations to avoid accidents. In the first case, may be, if the sidewalls of the terrace or road inside the parking building are raised to a height of - say 5 ft or more, could have prevented the person from scaling the height and protected the persons down below. But, in the second case, I do not know what can be done.
Such situations, even if brought out by any safety person, would have been laughed off as 'nonsense' and the person will be snubbed for thinking too wild. May be the risk level is very low, but not ZERO. As long as any opportunity is available to save the persons, the investment is worth as nobody can get back the life. The person's life may be valued at some amount and is compensated but he is more valuable to his family members than the compensation and this should be kept in mind. Else, surely there can be chaos and society has to bear it.

Hydrofluoric acid hazard potential
There is an article on HF hazard potential which I could not believe about its extent. What I know is that, if HF comes in contact with skin, it can cause burns, nasal rupture if inhaled, punctures and penetrates through the bone. But, the article mentions about its distance of impact of 2 miles from the source when travels as a cloud.
HF is used a catalyst in refineries to make high octane gasoline, as mentioned in the article. The IDLH is 30 ppm and it was found at 2 miles distance when 1000 gal was released from tanker containing 5000 gal at a pressure and temperature as used in refineries. The HF travelled as vapour and mist and needed 40 parts of water for every part of HF to dilute it, though the officials doing the experiment thought that it will remain as a liquid and can be contained. The article also mentioned about use of an additive to make HF less dangerous by way reducing its ability to form vapour cloud.
Few years ago, I read an article in the internet, in which a college girl died because of HF. When she was doing experiment, few HF drops splashed on her lab coat. She washed it with water for sometime and continued her lab work. She was found dead by her neighbours, the next day. The reason mentioned is that the vapour from lab coat was inhaled by the girl and this lead to oedema.
In a book on Bhopal accident, I read that few years before, in the same plant a similar death occurred from phosgene splash on the body. Here, the lesson is that we should not be complacent and assume that by washing for a minutes, the chemical can be cleaned. Once some chemical splashes, we should takeout the clothing. This should be followed with water wash.
Normally, as a safety precaution, one should wash for at least 15 minutes once any chemical splashes/falls on the body. Even then, studies show that only about 95% of the chemical on the skin can be washed off. During my safety lectures, I tell my audience that during the beginning of every shift, atleast once, they should check for availability of water in emergency shower/eye wash fountain and allow the water to run for few minutes so that any dirt/rust collected can run off. Else, the damage from this dirty water may be more than that from the chemical splash.

Side stand for two wheelers - their hazards
It is reported yesterday that a person fell from his two wheeler on the road divider and died on the way to hospital. The person fell because he parked his two wheeler on side stand and while taking the vehicle, he forgot to lift the side stand back to its position. When he was driving the vehicle, he drove over a speed breaker which hit the side stand that was in downward position and caused imbalance leading to fall of the driver. This side stand for two-wheelers appears to be very dangerous. On few occasions, I myself forgot to lift the stand and only when it hit something on the road, I realized my mistake and put it back to its rest position. And I watched many vehicle drivers, driving the two wheelers with side stand in downward position and passersby tried to point out the hazard to drivers.
Though parking a two wheeler on side stand is common, easy and may be a style statement, vehicle manufacturers should review this because of the danger it creates. At least some audio alarm should be provided when the side stand is in downward position when the ignition is switched ON. Best is to remove the side stand so that it will be safe and will not add to hazard potential of two wheeler driving.

Emergency escape routes - not available during emergency
Recently, a fire incident was reported in the basement of an office building in which three persons lost their lives. The reason for the death is not due to burns but because of asphyxiation. It is also reported that the fire fighters were unable to carryout rescue operations due to blocking of access and ventilation systems. About 10 years ago, a restaurant in Delhi airport also caught fire which started from the kitchen and people were unable to switchoff the exhaust (that spread the fire) as the switch was located at height and was not accessible.
Emergency accessories like manual call point, fire extinguishers, outward opening doors (emergency doors), stairs are those which we do not use day-to-day and it is seen in most of the establishments particularly in office buildings that these are blocked with junk items. The space under stairs is normally used as junkyard to keep mostly discarded chairs, tables, files, etc which are combustible. In basement areas, any fire involving these materials spreads fast due to natural draft and the same stairs which are required for fire fighting can't be used due to smoke coming up and due to poor visibility.
If fire fighters are equipped with fire resistant suits, self contained breathing apparatus and infra red cameras, only then they can approach the source to extinguish the fire. Else, they can become mute spectators. But, the building owners and others find it easy to blame the fire fighters for not doing anything, though the reason is because of greediness and shortsightedness of the building owners to ensure free access, maintain the areas free from combustibles and keeping constant vigil in these areas.
Some establishments provide fire extinguishers only to satisfy municipal authorities but they can be found behind some tables, or they are used to hold personal belongings like shirts, bags, etc and make them invisible. Sand buckets are generally used by employees as spittoons. If any construction or minor civil works are to be done, then these sand buckets are used for taking water, concrete, etc. The valve of the fire hydrant in the building (if provided) will be normally blocked with chairs. Or, the hydrant may not be in charged condition. Or, there is no water in the sump meant for this fire hydrant system.
In some buildings, the doors to emergency stairs are locked and this defeats the basic purpose of providing alternate stairs for use during emergency.
Many times the reason for fire is attributed to short circuit. A factory inspector in Tamilnadu based on his personal experience said that actually this is not at all the reason and if people can't find the reason, then they say short circuit as the reason. If short circuit is the reason, then all electrical wiring should be checked every year for their healthiness as we check earth pit resistance and electrical continuity between the switch and the earth pit. It should be made mandatory and checking should be done by only by approved third parties. Insurance companies should insist on these checks before providing the insurance cover. All basement areas and important rooms should be provided with CCTV cameras for surveillance. All corridors should have fluorescent (radiant) markings in the direction of nearest exit so that even in case of power failure one can see the glowing signs and escape. Emergency lights should be provided in the corridors and along the escape routes to provide minimum illumination. These lights should be capable of functioning atleast 30 minutes so that rescue operations also can be conducted. For high rise buildings, these lights should function for more duration as assessed by the fire services or similar agency.
Some pictures are shown below where fire fighting accessories are blocked/misused.Such conditions can be avoided and fire safety awareness can be increased among all employees including those in administration and similar services to ensure availability and misuse. These photos were collected from various online safety resources and their effort to create safety awareness and ensure safe workplace is acknowledged.
