LIFTS ARE DESIGNED TO BE "FAIL-SAFE"
- Highlighting a simple reserve facilities of lifts
We impute to a headlines reports upon 20thFebruary 2013 whereby a lady was killed when a lift plunged 5 floors after its cable snapped in a 10-storey unit retard during a Lumut naval base in Perak.
It is intolerable to note which nonetheless another open trickery unsuccessful to duty as well as killed a lady passenger. We should be thankful a lift was not fully occupied. The detriment of a single life is hideous enough. The subject which begs to be asked is because did this situation happen? Could you have taken required prevision to safeguard such incidents do not occur?
The answer is a resounding approbation as well as hinges upon a good as well as committed upkeep programme. For centuries rises have proven to be effective straight transportation systems as well as as engineers you can attest to this. We additionally know bad upkeep as well as even loosening can result in mishaps though you do have surety measures which can save lives.
Let us take a closer look during a reserve facilities of a lift. Each lift has a minimum of 5 hoisting cables as well as in a eventuality a single cable snaps a remainder four would safeguard protected travel in a lift. So because did all 5 cables give way simultaneously? This handle wire must be properly installed, aligned as well as calibrated by an experienced technician to duty effectively. Even with a snapped hoisting ropes a free descending lift automobile would be stopped by a automatic brakes upon a main beam rails as a last line of defence prior to it slammed upon a buffer in a pit. What is baffling is how all these reserve facilities unsuccessful to work.
The automatic as well as element specialists wil! l be abl e to give their professional as well as methodical views upon this impulse force which was so absolute which all strands of handle wire unsuccessful now as well as all during a same time.
We can really assume which bad upkeep or even no upkeep could be a means for this incident. The persons reserved to control unchanging upkeep work should provide a decisive reason upon a level of upkeep which has been carried out. The subject is whether a peculiarity of upkeep use supposing was below par. Were skilled technicians reserved to lift out upkeep works? Were genuine gangling tools used? If a answers are NO, it is only right which a suitable action in accordance with a applicable regulations be taken opposite a upkeep supplier.
We additionally believe which which Department of Occupational Safety as well as Health (DOSH) should do their part to safeguard which only certified lift vendors are purebred as upkeep companies to perform maintenance. We serve titillate a regulatory agency to manage all such upkeep companies to safeguard only efficient as well as competent individuals are appointed to lift out all upkeep work as well as to plead a work finished during a site.
We assimilate which there is a necessity of efficient as well as competent persons specialising in lift installation as well as upkeep work. We strongly recommendfor DOSH to plead more of such persons under a National Occupational Skill Standard (NOSS).
The IEM hopes which correct investigations will be carried out to determine a means of a mishap. If there is a need, a IEM will be pleased to suggest its services.
