[MERGED] Occupational Safety & Health /NIOSH

After reading the news report, I beg to differ as to the reason for the explosion written. Facts which obviously are not available to the reporters.
1. An LPG cylinder is designed to maximum 20 bar - or 300 psi, to contain liquefied Propane (70%) and Butane (30%). The pressure only comes from the propane, as the butane has almost no pressure. Check your cigarette lighter. Pressure can build up only if the liquid is vaporised.
2. This is important. The NGV cylinder is something like a BA (breathing apparatus), with similar pressures. The steel tank is normally designed for 200 bar - or 3,000 psi, 10 times the pressure for the LPG! If you want more gas, you will have to use an even higher pressure but that will increase the thickness of the cylinder required, and the weight will become prohibitive. In which case, composite material is the alternative.
3. What happened in this incident is that the LPG sphere was filled beyond its capacity and exploded - this is a physical explosion! The gas released was ignited almost immediately by the engine which was running - and this caused a second fire explosion! But the timing could be very fast and almost simultaneous. Most people would not have identified it as 2 explosions.
4. As a result the public must be made aware of the fact that any LPG cylinder is 10 times inferior to the NGV cylinder, in terms of pressure. Use the LPGcylinder, and you will have a time bomb in your hands.

From my discussion group otai NIOSH, Ir Daud. ANy Comment?

ooo..ni unsafe act lah ek...huhu

hehe.kiteorg ade group bincap pasal safety issues nih...so kiteorg bincang pasal fire extinguisher yang meletup kat johor..yang mati tuh student kawan aku..huhu..

wahhh..x sngka ade discussion psl safety nie,x jmpe pun b4 dis..
bole lar join sekaki..girl nak amik master kat ukm yek,sme ler kite..
me dah survey jgk ari tue,tp bla tgk kos aduih...xckp ongkos nya...

ni semua melibatkan polisi kerajaan. COntoh sabun. Kalau guna di rumah no prob tapi kalau guna kat hotel dah kira industrial use dan perlu CHRA assesment dan pelbagai keperluan dlam USECHH 2000.

Anyway sedikit info kod kerajaan berkait dengan OSH

PMA - Permit Mesin Angkat
PMT - Permit Mesin Tekanan
PMD - Permit Mesin Dandang

Regards and Peace
