Dehumidifier

That sounds more plausible. 20 deaths per week would be shocking.

Surprised to hear you voice that opinion.

So safety procedures do not need to be followed by "sensible" people,it is just the rest of the population that should follow them.

My understanding of the statistics is around 1000 people a year die from electrocutions and 30000 injured, so approximately 20 deaths per week. I would have thought on an energy board those fiqures would merit attention not derision.

I’m not deriding anything - but there is a difference between doing everything to the letter of the rule book, and using a degree of common sense to make life more practical. I’m currently sitting in a room with both a fire and candles lit - you may well feel that neither of those things are “safe” - but we will always extinguish the candles before going to bed, and the fire gets its guard put in place every time the room is left unattended even for a few moments. My view is that while the situation isn’t without risk, it’s possible to mitigate that risk. 

Your use of those figures is interesting - those are worldwide figures  by the look of it, so include places where the electrical regulations are far less stringent than they are in the U.K.? The U.K. statistics are notable in fact by how low they are. The only specific record of a U.K. death I could find relating directly to a dehumidifier involved a man who drank the liquid from the tank of one - don’t do this, kids, he died of multiple organ failure according to the news report. It doesn’t seem to say whether the dehumidifier was in the bathroom at the time. 

The reason for sockets not being approved to be fitted closer than 3m to a bath or shower is as I recall to reduce the risk of an appliance like a hairdryer being dropped into the water - nothing to do with those appliances being used in a damp environment as such.

If those figures are global, 20 deaths a week is frankly infinitesimal with a population of over 8 billion people. 

Compare to road traffic accidents, people drowning whilst swimming in the sea...

Edit: according to Google 400 people die from accidental drowning in the UK each year. Globally it's 300.000 die from drowning.

Last year in the UK around 1600 people died in a road accident, and around 25,000 died from heart attacks.

This worldwide or USA figure also seems to include deaths in the workplace. About 4 of the 20 are from electrocution in the home.

Overall the rate of electrocution worldwide is estimated to be about 10x higher in the workplace. Obviously not as bad as that in developed economies.

Apologies about the figures, I googled deaths by electrocution in UK, it then lead me to a site called Electrocuted.Com, which I did not realise in my haste was a USA based site, can only apologise but I did think those fiqures related to the UK.

The tank capacity you need will depend on how long you want to run it for unattended,  I run mine for 7 hours overnight and 12 litres would not be sufficient.

@Reed_Richards are you saying that you're dehumidifying a space (I'm assuming not a home) where you are pulling more than 12 litres of water from the air in a seven hour period?

That's huge.

From the Meaco table that Scot_39 shared, you'd need to be running nine of their "12 litre" dehumidifiers in a 30C, 60%RH environment to achieve that.

Are you trying to dehumidify an indoor heated swimming pool?

My worst conditions for humidity are in the summer when the outside air is warm and can hold a lot of moisture.  From time to time we forget to empty the dehumidifier in the morning and it stops (automatically when full) at some time during the following night.  When we do remember to empty it after 7 hours of use, it is often well more than half full (with a nominal 20 litre capacity).  I live in a bungalow; the dehumidifier is centrally positioned in the living room/dining room area but the doors to most of the other rooms in the house are open so it is dehumidifying a large volume of space.

Just at the moment it is 10 C outside, the outside humidity is 96%.  Inside it is 20 C and 60% humidity.

Thanks Reed. Can I just focus in on this bit:

A 20 litre water tank would be huge, as big as one of these:

Are you sure you're not confusing the rating of the dehumidifier (which is typically the amount of water it can pull out of the air, per day, at 30C and 80% RH) with the size of the tank?

As discussed a couple of pages back, the tank size is usually much smaller than the rated capacity. A 20 litre dehumidifier like this one only has a 4.8 litre tank.

Even this commercial model rated at 50 litres only has a 5.5 litre tank.
