Road To Work



A beautiful day indeed, really brings up my mood..
Today is 30th June 2010... an inspection will be done on this very day..
Only 2 units of boiler scheduled for today and I hope that there would be no problem arises.



Here I am doing my job.. inspection of a boiler.. now i'm in water side of the particular boiler.. There's the manhole which got me in.. Boiler is an any enclosed vessel in which for any purpose steam is generated under pressure greater than atmospheric pressure, and includes any economiser used to heat water being fed to the vessel, any superheater used for heating steam, any pipes and fittings connected thereto. The key word is steam generated. Boiler can be fire tube, water tube, electric boiler, waste heat boiler and combi boiler. The boiler I'm in, is a fire tube boiler.



The condition for the water side in not satisfactory. It is because of the whitish scale observed covered all the tubes and also the shell. In my personal opinion, this occurs because hardness is not properly control. It's suspected, mainly, consists of calcium and silica.



Now i'm in a furnace, through that manhole.. this is a wetback boiler and consists of 3 pass of flue gas/hot gas.



Defect that I found on the 2nd pass. Stay tube is cracked. How on earth this could happen. It's a stay tube for boiler sake.. so.. my conclusion is whether is right or not, is that... inproper heat distribution, heat transfer rate, region is not properly in place... may be the scale which covered the tubes can tell us more..



Then I've finised my on situ work. I went back to my office to write down my findings for today inspection..
What a day...

FuN FoR ProFit: Way Back Home

FuN FoR ProFit: Way Back Home

Way Back Home



Here I am, driving towards my home, on penang bridge on 25th june 2010 around 5.55 pm....erm.. quite a heavy traffic.. i think it's gonna be 'jamming' quite soon enough..



Now, I'm stuck in the traffic.... huh..
and there lies TNB Power Plant.. 2nd tallest tower in Penang after KOMTAR... I've been there for quite some occasions...
Mostly for the HRSG inspection..
This power plant have 2 units of Heat Recovery Steam Generator (HRSG) or Waste Heat Recovery which supplies electricity throughout Penang and some other places in the northern region. This particular power plant is powered by a natural gas, brought in, all the way from Kulim in a pipeline.




Continuing with my journey home... and following the car in front creating a new lane...




Erm, a college...



and I'm heading to my home happily and safely..

Escalator & Lift Accident


Don't let crocs do this to your loved ones feet


Always put an eye upon your kids whenever there's an escalator


Remember, there's no second hand arm on the market.


Don't take this messages for granted!!
Let's culturized our nations with safety attitude.

LIFTS DEFECTS

Car and landing bay is not level which creating a hazard.




















Wire rope is now experiencing fretting corrosion which also known as 'Red Dust'
















Lift Car platform found to be rusted.
This happens when always mopping on the rubber mat.
As user, this is untolerable.

















This defect found during an inspection.
Counterweight spring tension was broken.

RISK TOOLS FOR SAFETY

Basically there are several tools can be used in findings hazard and risk.
Below is commonly used tools.

1. Job Safety Analysis - JSA
2. Hazard Operability Study - HAZOP
3. Hazard Analysis - HAZAN
4. Fault Tree Analysis - FTA
5. Hazard Identifiations Risk Assessment Risk Control - HIRARC




1. Job Safety Analysis.

Introduction.

Generally, JSA is the easiest way to identify hazards and to determine the best way to reduce the hazard.In the other word, walk the walk of the specified job. It's easy when walk through method is used.

Performing JSA
There are five simple steps to perform this tools.

1st Step
Select any job to analyze.

2nd Step
List down basic job steps.

3rd Step
Identify Hazards in each step.

4th Step
Control each Hazards.

5th Step
Review the JSA.

2. Hazard Operability Study - HAZOP

Introduction.
A Hazard and Operability (HAZOP) study is a structured and systematic examination of a planned or existing process or operation in order to identify and evaluate problems that may represent risks to personnel or equipment, or prevent efficient operation. The HAZOP technique was initially developed to analyze chemical process systems, but has later been extended to other types of systems and also to complex operations and to software systems. A HAZOP is a qualitative technique based on guide-words and is carried out by a multi-disciplinary team (HAZOP team) during a set of meetings.


There are three basic types of causes. They are:
1 . Human error which are acts of omission or commission by an operator, designer,
constructor or other person creating a hazard that could possibly result in a release of hazardous or flammable material.

2. Equipment failure in which a mechanical, structural or operating failure results in the release of hazardous or flammable material.

3. External Events in which items outside the unit being reviewed affect the operation of the unit to the extent that the release of hazardous or flammable material is possible.
External events include upsets on adjacent units affecting the safe operation of the unit or node) being studied, loss of utilities, and exposure from weather and seismic
activity.

METHOD

1. Standard Guide Words used in identifying Deviations, the Study Leader applies (systematically, in order)



2. Overview of commonly used guide words and parameter




3. HAZOP basically carried out by a set of team.
