does anyone know if it is safer to use LPG or deisel indoor, what is the difference between emissions etc, deisels are alot cleaner than they used to be, and LPG is not as cheap as it used to be. Is there any laws preventing use of deisels indoors, I'm interested in any opinions on this subject.

The primary issue with diesel is the NOX emissions and the smell (but alot of that has been cleaned up with recent emission standards & use of cataltic convertors use). Diesels produce less CO emisions than do LP or gasoline fuel.

I have sold the Linde units with diesel engines in to warehosue applications successfully with no issues. No exhaust emission smell or smoke issues, in fact one customer told me that they can have lunch behind the units with the engine running. I would not reccommend a diesel for a stop and go applications as a diesel is more efficent when it is running continously

In the past diesel units were not a good choice for "continueous" indoor applications because of the "sooty" smoke and fumes they emitted. The newer diesels equipped with catylitic mufflers are doing a lot better at reducing the NOX emissions as well as the smell. Proper and adequate ventilation is a must!! as with any internal cumbustion engine. Fresh air must be coming in at all times, exhausting the bad air. Proper and regular maintenance on diesel units is important to keep away "pre-CAT" exhaust leaks and rich or incomplete combustion issues.

I would NOT recommend using diesel units in a "Closed" type building or warehouse unless it had an "Air exchanger" type of ventilation system.

does anyone know what is the cheapest to run, (mainly fuel costs). Is there much of a saving on fuel.

to Leon W: What is the price of "Off Road" and hiway diesel in your part of the world? It is $4.05( US gallon )out here for hiway fuel and around $3.50 (US gallon) for "Off Road"

highway fuel is £1.20 per litre and off road about £0.75, lpg bottles are £15 for a 18kg bottle approx 29 litres.

Does anyone have the nox figure for a kubota V3300 or the Nissan K21 with impco lpg system with standard exhaust system.

Having spent over 20 years in the industry, it never ceases to amaze me that people don't go electric whenever possible in the application is indoor. The initial expense of the vehicle, the battery and charger, etc., is expensive, but electrics do not have emissions and over the normal life, use less than half the parts and service of an internal combustion vehicle. Also, it's not so much what the vehicle effluent is to the indoor environment as much as it is the ventilation of the indoor environment. The more closed, the less acceptable an IC vehicle is. Personally, with all the continuing 'green' emphasis worldwide, I'd recommend starting to get into electrics wherever possible and learn how to optomize the battery life.

Morf is right, and here's 1 more point...

If you use fuel-cells, you eliminate the charge times as well.

Some years ago, the EPA was looking at banning ALL IC trucks indoors. That fell through, but you can be assured, it will be passed someday...

    Companies who use forklifts indoors need to be prepared for the change to electric units, it just a matter of time before it happens.
    Electric trucks have come a long way in the last few years, AC power has made it more practical and cost effective.
    Maintenance intervals are longer and less parts to deal with and the new battery technology that is evolving is making it more practical to change.
    The initial costs of the change and battery handling issues scare some folks away from it, But savings in the long run will eventually be noticed.

The problem with electric trucks when comparing emissions is that people quite often fail to take into account LCA and assume its a clean fuel. OK, maybe it is in Scandinavia where electricity production is mainly Hydro Electric but in the rest of the world that is not the case.

For comparitive emissions using CO2 as the base:

LPG - 0.234 kg/Kwh
Oil - 0.265 kg/Kwh
Electric - 0.422 kg/Kwh

If you take an average bulk price in the UK, then you're looking at circa 40ppl compared to 55ppl for red diesel rising to in excess of 90ppl for bunded product. So, to suggest that one form of energy clearly provides benefits over another is misleading because, although there is now more overlap between the fuels in terms of benefits/operational usage you cannot state that one should be used in all cases.

For indoor use, another consideration is the noise level. Electric trucks are always recommended for indoor use, not only due to polluted fumes, but also the noise level.
