Oxygen Masks in Lavatories?

From my reading of JAR-OPS it is unclear whether they are required--1.770(b)(2)(iii) says "...shall be provided an oxygen dispensing unit connected to oxygen supply terminals immediately available to each occupant, wherever seated." That of course brings up the question of what happens should the cabin suffer an explosive decompression while you're occupied having relief.

So, are oxygen masks fitted in the toilets or aren't they?

They're certainly needed in my lavvy, esp after longhaul to Mumbai by way of Brick Lane. Explosive decompression don't enter into it.

Meanwhile, and slightly more fragrantly, why are there still ash trays, marked as such, in the loos? Shouldn't they be decommissioned?

They are there to encourage those who do happen to smoke (even though it is banned) to place their butt in.

It is much better than putting it in the waste paper bin.

I'm wondering, just how much does this actually happen nowadays ? Do the detectors usually catch it ?

WHBM,

Very rare to see it. When it does happen, you will find that the F/As have zero patience and will quickly open the door to find the source of the tobacco smell. They do this not to catch the smoker, but to prevent the potential result of putting a butt in the trashcan.

Many will recall this DC-9 accident that killed 23 people.

Masks are not necessary in the toilet, you can declare your toilet u/s and lock the door from the outside.

This wasn't caused by a fag in the bin.

This was the flusher motor over heating infact.

But agreed, masks should be in all commerical a/c,

What about the masks in the galley? Is there a spare one or just 4 (2+2) above each jump seat?

In fact, the safety board never ruled out that a cigarette could have caused this fire. It could not be proven for sure where the fire came from.

Lav Ash Trays

Agree they seem ridiculous in this day and age but it is a 'Part 25' requirement...Ash tray inside and outside the lav with the appropriate signage etc. In fact would be theoretically illegal to operate with out both ash trays fitted and working....Its the same with the pax seat....however that (pax seat ash trays) can be got round by hard wiring the No Smoking lights on at all times and getting approval to operate in that manner.

splashbrooke, of course it's too late to declare a toilet unservicable when there is already someone in it

You have to do it before! (Would you want to close the toilet from outside if there is someone in there??? )

Rwy in Sight, there are also masks over the galley and/or above the jump seats. Depending on type, just enough or even more than needed.

On the 744 there are actually extinguishant systems for the bin.

As to Oxy Masks, yes they are required in the toilet.

Dani is right, it doesn't have to be serviceable, but if that is the case then the toilet would be locked unservicable PREFLIGHT. So, masks are required in a serviceable toilet.

We could just design the aircraft without masks in the toilets, and then just have them unservicable permanantly . Short flights only haha.

As to the Ash Trays in the toilet doors... there are still airlines that allow smoking, so it would be a general design and certification issue. In fact, our MEL requires that they are all serviceable or no dispatch! (Even as a non-smoking airline).
