Very informative...kindly make another one for refilling Dcp & foam extn. Thanks.
Noted.😊
I respect, admire and appreciate the kind of work you are doing 🙏
Thank you for your good comments mate
I really appreciate your job done for knowledge of fresher third mate they learn how to maintain all the LSA. I REQUESTED YOU TO MAKE ALL THE INSPECTION VIDEO WHATEVER THE THIRD MATE HAVE TO BE CARRIED OUT . SO THE FRESHER GET THE KNOWLEDGE AND APPLY IT ON SHIP THAT WILL BE BENIFICIAL
Thanks mate....do share with your sailor friends
plz make video of recharging extinguishers...
Important video. Thank you sir
👍
The same here and like for all others your video. You are doing not full visual inspection.
You must check the whole unit which means that you must check the base/bottom of the extinguishers to check if there is no any damage or rust.
Sir pls making future video about semi portable extinguisher & steam extinguisher for extinguishing scavenge fire, thank you.
Well noted
Kindly make video on refilling the extinguisher and how to refill it
Especially foam extinguisher and also for DCP type extinguisher
Noted
Every portable extinguishers are having vent holes or not?,
What is atmospheric valve?,
What are they extinguishers are having pressure gauge?,
how control valve is used to control the extinguishing agent of PFE,
How valve head assembly is working.
Regulations in PFE nozzle.
Pls tell these questions sir, thanks in advance.
No every portable extinguisher doesn't have vent holes
Cartridge type extinguishers have vent hole in cap assembly as when you strike the plunger it punctures the cartridge of extinguisher and try to expell the extinguishing media
If there is any choke/obstruction for expelling the extinguishing media then in order to release the pressure build up in extinguisher vent hole is provided
Related to atmospheric valve what I guess is about snifter valve located in cap assembly
Snifter valve is located in cap assembly of extinguisher for water and foam and that to for cartridge type only so that when the extinguisher is placed near any heat I mean exposed directly to sun light then those liquid start to boil and due to internal pressure those liquid will be expelled out with operating the extinguisher
In order to prevent that and release those presuure snifter valve is present in cap assembly which releases the pressure build up inside
Related to pressure guage stored pressure type are fitted with pressure gauge
Hi . Can u tell FIXED system for deep fryer galley . Uses which extinguishing medium . TIA
Nice information
Thanks ❤️
Fantastic
Thanks
Can you please tell us about DCP. On which class of fire we can use DCP. Please if possible can u load just photo of DCP mentioning class of fire on which it can be use.. please
As per ISGOTT 6, PAGE 101, Dry chemical can be used in all types of fire like class A, B,C,D,E but mostly dry chemical is used in LPG ships, that is class C, Also do keep in mind that Dry chemical inhibits the chemical reaction to extinguish fire.
Why DCP extinguisher is not used in electrical fires.
What is the meaning of that green color circle on the cap of fire extinguisher?
Can u demonstrate us how to recharge dcp and foam extinguisher?
Noted
@@SailorVikas i'm waiting for it
@@dirilisertugrul8902 yup it's their in my list...
Sir I wanted to know this pressurize gas like co2 extinguisher wen we trigger the lever we can use remaining but CO2 cartridge like foam dcp once we puncture the cartridge we can't use back the extinguisher no??
You can re-use the extinguisher after replacing the punctured cartridge in case of DCP and foam but cannot reuse CO2 extinguisher ( thus you need 100% spare of it ). For CO2 extinguisher you have to land it ashore for refilling.
Hi sir I heard that in portable extinguishers there will be relief holes ? Can anybody brief me about that location and working
Done with red marking, present near nozzle regulator
Sir strictly needed hydrolic testing for inspection
Captain I'm very happy to subscribe your channel there's a lot more to learn in deep about merchant vessel than I thought.
Captain I'm asking you to download your videos for education purpose as you know on ships we have limited access to internet. If you allow me I'll download only for education purpose if you dont it's ok
Thank you for giving us this channel this helped me a lot for MMD exam.
Yes mate, learning is free here on my channel so download as you want but make sure you share with your juniors about my channel 😝😝😝
@@SailorVikas I'm super thrilled sir to have a positive reply from you and to be honest I really prefer your channel to everyone that I know of. Much love captain ✌
@@BilalAhmed-sl3cc thanks mate ❤️
Hi, can u please clarify what the "First 10 extinguishers" mean? First 10 in what manner or type?
First 10 in each type
What is the difference between dip tube & Siphon tube in portable extinguisher.
Both are same thing...dip tube is a tube having opening from bottom...it's dipped inside dcp or foam liquid ....when pressure is created by punchtured CO2 cartridge, dcp or foam comes out thru dip tube.
@@SailorVikas thank you sir.
How many extinguishers to be carried on board for 50m 100m 150m 200m vessel
Their is no specific number mentioned in SOLAS convention however it should meet basic requirements like CO2 extinguishers in spaces where we have electric machineries and DCP/Foam in accomodation and so on.
sir what is the standard weight of cartridges in dcp and foam extinguishers???
There is no cartridge for CO2 bcose it is pressurize no chance of pressure getting less no?? but extinguisher having cartridge there is chance of cartridge getting expired by mistake n someone can put the pin back but by gauge we will know the pressure no?
Yeah
@@SailorVikas sir why they say co2 cant be used on electricity it's a gas no ?foam can't be used its liquid chemical but CO2 why it's not used they say electric cables ya equipment can get damage?how come we cant use?
@@astlefernandes1429 where did you see this ? In all areas where you have electrical panels like bridge, CCR, GALLEY, Switchboard room, emergency generator room, everywhere you will see CO2 extinguisher.
@@SailorVikassir I agree wat u told but I got this answer from one officer saying it's liquified gas under room temperature liquid can get damage electrical equipments
@@astlefernandes1429 yes but CO2 you will not direct it on equipment, you will have to smother the fire so even if you supply CO2 in surrounding area of fire it help extinguish fire.
Foam type extinguisher color code cream
Any Requirements for CO2 cartridges? How many to be carried?
100% spares for cartridges
Very knwlable bro
Thankyou
excuse me mate it is possible to paint the fire extinghuser if found rust?
Small patchwork can be done, if rusted heavily than replace
@@SailorVikas ok thank you mate
How to identify any cracks in the internal pipe of the PFE.
Well pipe which is internal ?
That can b inspected after opening the extinguisher from top, but it's annually Inspected by shore...no requirement to inspect inside extinguisher
In annual inspection do they open extinguisher ?
Then what about foam or powder....same is used ? ...... as recharging is done only after 5 years.
Yes they do open up ...for powder and foam, they remove the contents in bucket, check for caking or any other problems, inspect inside extinguisher and they put the same content back...
In my case the CO2 cartridge of few extinguisher were found fallen down inside extinguisher, when they opened up the extinguisher.
And yes for recharging u have to land it ashore ....they will recharge, carryout out 5 yearly Inspection and they will put 5yearly Inspection tag and return u back the extinguisher.
@@SailorVikas why the lable writted 5 yearly hydrostatic test. it isn't should be 10yearly?
It differs from manufacturer to manufacturer, some have 5 yr and some have 10 yr, so you have to comply with least period when compared between flag state requirements and manufacture requirements.
very informative ...can you please tell what the criteria is for changing the CO2 cartages
It's very simple, rotate cartridge anticlockwise to remove old punctured cartridge and rotate new cartridge clockwise in its thread to fit back new cartridge
Sir, pls tell me every portable extinguisher is having safety pin or only similar portable extinguisher is having safety pin?
Yes every portable extinguisher should have safety pin to prevent accidental release.
Thank you sir.
but what is the weight of CO2 cartridge ?
Around 220g
Do we have any requirement of co2 cartridge to be used in water,foam and dcp extenguisher? Like of weight or pressure of cartridge!!
Written in LSA FFA training manual or makers manual , can get cartridge details from their.
So sir i must have 100% spare co2 fire extinguisher, and 100% first ten fire extinguisher ( it mean 10 pcs fire extinguisher like foam extinguisher ready to use for example) and 50% of other fire extinguisher like dry powder of total onboard dp fire extinguisher i have? And for catridge ad refill i must have 100% of total our fire extinguisher onboard, am i right?
Spare charges shall be provided for 100% of the first 10 extinguishers and 50% of the remaining fire extinguishers capable of being recharged onboard. Not more than 60 total spare charges are required.
For fire extinguishers which can not be recharged onboard, additional portable fire extinguishers of the same quantity, type, capacity and number as determined in above shall be provided.
How often should to refill the fire extinguisher?
It is done as per manufacturers instructions, some want it to refill annually and some manufacturers want it to refill 5 yearly
@@SailorVikas All Fire extinguisher do hydrostatic test every 10years? foam type Also 10years to do hydrostatic test?
@@jianmingzhou5156 yes mostly flag state requirements have 10 years But do check if manufacturers say less than comply with less ( for eg 5 yrs )
@@SailorVikas if the manufacturer didn't mention how often should to replace the extinguishing agents ,then how often should we to refill the fire extinguisher
@@jianmingzhou5156 if you check in extinguisher itself in bottom area, replace or refill the contents of extinguisher is written, rare chances that you won't find it, if not mentioned, than follow flag state requirements and it will be mostly 5 years
good day sir, what does 100% for the 1st 10 extinguishers mean?
If u have 15 extinguishers of foam than 1st ten extinguishers (i.e.10 No.s) should have 100% spares ( foam liquid + cartridges) and 50% spares of rest extinguishers
@@SailorVikas okay sir, now i understand it better, thanks for the explanation and kodus for the fast response. More power!!
Thanks
Pls clear that is there any requirement to discharge extinguishers onboard ?
Yes their is a requirement.
Requirement depends on flag state.
For eg. Singapore flag says to discharge one each type of extinguisher, which can be recharged onboard ONE YEARLY, however if company policy says you have to discharge every 2 months so you have to discharge every 2 months and maintain proper records.
In complying with company requirements, flag state requirement is fulfilled so no need to discharge extinguisher separately.
@@SailorVikas thanks
@@SailorVikas how to do discharge test for pressure stored extinguisher. as they can't recharge on board. discharge test is to choose one extinguisher of same type or all all the extinguisher need to do discharge test
Only those extinguishers which can be recharged onboard has to be discharged. CO2 cannot be refilled on ship so no need to discharge. Similarly if you have pressurised DCP or FOAM Extinguisher than no need of discharging that, but if it is rechargeable onbd than surely you have to discharge as per flag state and company requirements
@@SailorVikas As IMO only 5yearly need to do discharge test and only discharge 1Pcs Same type fire extinguisher. Is that right?
Where that pressure gauge on dcp is connected is it to the catridge or main body ?
If their is pressure gauge in fire extinguisher if means it doesn't have cartridge. The whole extinguisher is pressurized.
@@SailorVikas But the one with catridge system will be havimg one imdication right showimg the green and red zones .i am asking about that gauge may i know where that gauge will.be connected ?
It's connected near to the extinguisher plunger. On the top area
You can check in internet ...their will be plenty pictures
@@SailorVikas ok sir i got it but my question is that what pressure it is showing is it showimg the catridge pressure or the main container?
Do they have pressure gauge?
Some have ...some don't...depends on manufacturers
how can we refil foam on board & what are diff type of foam??
Refilling is very simple. In makers manual it would be written the foam:water ratio to be mixed. And foam liquid u ll get In small cans for each extinguisher, so make just mix the ratio in a bucket and pour it into empty extinguisher, connect new cartridge and box pack it.
@@SailorVikas new cartridge Or the old one I will put back
@@MdAsif-fo2fx if old is punctured, use new one
@@MdAsif-fo2fx cartirdges have expiry too...approx 4-5 years
Hello sir ,In this video for foam colour code is cream colour but you mentioned as yellow, yellow for wet chemical
