Spark Arrestor For Vehicles Exhaust Pipe

...wait...nah...well?....are you asking what I think you are asking?

Are you looking for a spark arrestor to alleviate your concerns about a spark generated in the engine and traveling out the exhaust pipe is going to create a hazard in an area with sufficiently high concentrations of flammable gas?

.

I would thing any sparks making it all the way out the exhaust pipe would would be fairly low concern compared to the numerous other potential sources of ignition from a random assortment of vehicles.

Quite. Bicycles with EEx d head- and tail-lights may well be the way forward.

your suggestion is valid if someone want to carryout patrolling around the small facility. However , if the oil and gas installtion is of huge size and nature of work involves enevitably plying of vehicle in hydrocaron laden explosive environment to carryout operational and maintenace works then one is bound install spart arrestor at the ignition source .

'....then one is bound install sparK arrestor at the ignition source....'

.

The problem you are asking a question about implementing what will be an ineffective solution based on a flawed assumption. You need to back up a couple of steps.

.

Better questions you could be asking might be:

-In a typical gasoline or diesel powered vehicle, what are the possible sources of ignition if driven into an atmosphere with a combustible mixture of gasses?

-Can typical diesel or gasoline vehicles be economically converted to be safe in combustible atmospheres?

-If so, what would be the approximate cost on a per vehicle basis?

-What is the difference between a spark arrestor and a flame arrestor?

-Does anyone sell an affordable, vehicle-encompassing, mobile flame arrestor?

.

.

There are numerous potential sources of ignition on most typical vehicles that are far more likely in most cases to initiate an explosion than a spark making it out the tail pipe.

It does rather sound as though the facility has a process materials containment problem to address.

It does rather sound as though Zone 2 is too large.

Tackle those first.

Exactly. If you allow an operating vehicle and a flammable mixture to exist in the same area, you must assume ignition will take place.

In processes area of almost all oil and Gas sector hydrocarbon environment prevails all the time at certain level of explosive limit which can cause fire if any source of ignition enters or created. There have been certain major accidents in the history of oil and gas sector because of these situuation. Therefore , ignoring the potential of fire due to low magnituge if ignition source is never considered safe becasue explosive limit can increase any time due to relase of any hydrocarbon vapour cloud due to some chnage in processing condition in plant .

'....Therefore , ignoring the potential of fire due to low magnituDe if ignition source is never considered safe....'

.

sure.

.

In a similar light, requesting information for implementing a solution that focuses on solving only one contributing factor effectively turning a blind eye toward a multitude of more significant independent factors,..... is misguided.

.

Doing it insistently, if at least foolish.

.

I do have faith that those ultimately responsible for the facility have measures in place to insure this doesn't escale from foolish to dangerous.

Google Spark Arrestors. These are common on forklifts.

Perhaps you mean static grounding protection for vehicles (such as tankers).

You CANNOT attach devices to standard vehicles to make them Ex - rated for use in Zone 1 or Zone 2 gas environments (standard specific) as both spark AND heat sources need to be carefully controlled in a certified manor.

Perhaps you should talk to a local hazardous area inspector.

Static grounding is done with petroleum product carrying & handling vehicle and equipments respectively because static charge is produced when oil is in flow . My concern is to install spark arrestor over the exhasut of Inter combustion engine based vehicles which are used for transpotation purposes within the hydron carbon environment . Spark arrestor is considered the best solution to tap the ignition generated from vehicles .

Look. Learning is so much easier when you give up on the idea of projecting personal infallibility.

.

The smartest people I know continue to get smarter, because the are always receptive to learning; none of them exhibit any significant investment of ego in being right, or being seen as so smart that there is nothing they don't already know. I often hear them say things similar to 'That is interesting/unexpected', or 'Could you explain in more detail'.

.

They don't behave that way because they are smart....they are smart (at least in part) because they behave that way.

The spark arrestors that go on vehicles that I am aware of are typically used to reduce the possibility that glowing hot piece of material from an IC engine exhaust does not reach something like dry detritus start a wild fire. The word 'spark' used in that sense isn't the same as the electrical 'spark' that is also an ignition risk in a combustible gas environment.

.

On a typical automobile, stopping glowing embers coming out the tail pipe is one of a myriad of ignition hazards for combustible environments...probably no where near the most threatening.

.

Contacts in numerous relays-

the occasional loose light bulb-

the surface temperature of the exhaust header or turbo-

the starter, sliding contacts on the alternator-

Those are a just a few places that could provide ignition of a combustible atmosphere.

.

None of those risks can really be mitigated with a spark arrestor, or by grounding the frame against static buildup. Retro fitting vehicles is not going to consist of merely slapping a spark arrestor to the exhaust.

I agree to your view point and thanks to you for indicating other areas of vehicles that can also contribute to generate source of ignition . That means ensuring proper fittness of vehicle is also one of the prime fcator to rduce the hazard.

Contact in relays are normally concealled in a box by car manufacturer.

Loose bulb must be checked priodically .

Surface temperarure of the exhaust header can be further reduced by providing fins

to increse the surface area of air cooled mechaniacl

I have not a complete idea of other areas .Therefore , i will check them and then see what can be done about it .

MY concern is that you are not following your local hazardous area standards and regulations. Please refer to them as what you propose just plain won't work AND is highly illegal in most countries I am aware of. Stating the same thing over and over again here will not change what is written in the standards or how hazardous area protection schemes actually work.
