What are the procedures involved for F/A's in the event a decompression occurs while cabin service is going on. Is there enough time to run back to the galley and don O2 masks? Are there masks that drop down over the aisles?

There have always been "extra" masks in some of the overhead units. Anymore there are probably extras in every single PSU.

They are trained to grab a nearby one take a breath, swap it for the next one along in the direction they are going and so on until they get to their walkaround bottle.

Flight attendants correct me or update me as you see fit.

Our policy at WN is "Grab oxygen and secure yourself." Ultimately we try to make it to our POB's (Portable Oxygen Bottles) so that we can move through the cabin and assess pax injuries, open faulty mask compartments etc. We're also trained to turn all lights to bright and make a memorized PA, something like:

"Ladies and Gentleman pull down on the mask in front of you, place it over your nose and mouth a breath normally. The bag may not inflate, you are receiving oxygen. Fasten seatbelts and Positively no smoking."

Each row of 3 seats is equipped with 4 masks which allows for one lap child per row...never more than 4 souls total per row; so there are always extra masks throughout the cabin, as well as above each jumpseat and in the lavatory as well.

breath normally.

Truth is, if you can breathe normally you haven't grasped the seriousness of the situation.

Apparently not on every aircraft in every row. On the SK 330 we flew only every other row had an extra mask. So we couldn't sit just anywhere with our daughter.

At U2 all our aircraft have 4 masks per PSU. In the event of a rapid decompression we take a spare seat/wedge ourselves between pax and take a mask. Trolleys are secured as best as possible (brake/wedge/pour hot water onto floor). Once the descent is complete the FD initiate the emergency drill with a call to the cabin, which is when we can "monkey" on spare masks to get our portable oxygen.

On A32x aircraft, when the masks are deployed, the CIDS makes an automatic PA, turns the seatbelt signs on (but not the return to seat signs in the lavs) and sets all cabin lighting to 100%.

Generally, the safety procedures I have read are:

1) Flight attendant grabs nearest mask, puts it on
2) Flight attendant sits down in nearest seat, in anticipation of rapid descent,and fasten seat belt. If no seat is available, flight attendant is to wedge themselves in between the seats and hold on!
4) Commands can be shouted through the mask; sound may be distorted due to the mask wearing so motions may be need. Typically the commands are "GRAB MASK, FASTEN SEAT BELT!". Passengers frequently forget to extend the tubing enough to pull the activation or firing pin.
5) After the descent is complete, the flight deck will make an announcement.
6) Flight attendants can then move about the cabin, but should secure a POB bottle and administer first aid as necessary.

What concerns me is that flight attendants should avoid, whenever possible, trying to go from "mask to mask" down an aisle unless the descent is already complete (which Wexcan noted). The flow rate of the masks are VERY low (2 liters of oxygen per minute), is diluted with cabin air (reducing O2 concentration further), coupled with increased physiological demands of the flight attendant (you're moving around, doing things, unlike a seated pax) increases the risk of the flight attendant becoming incapacitated even though they are going mask to mask.

The exception, is, of course, a situation like Helios where the cabin crew needs to check the flight deck if a descent has not yet occurred after the masks drop.



Release your seat-belts and get out! Leave everything!

Thanks for the info everyone. That makes perfect sense.

Our procedures are pretty much the same as the EZY ones. As soon as you see the masks, grab a spare one and either sit on an empty seat, pax lap, or wedge yourself in. Try and wedge the cart between a row of seats, or even push it over onto its side (depending on the steepness of descent), pour tea / coffee pots onto the floor (water will boil over), be aware of drink cans popping, and shout commands to nearby pax in between breaths (we have a memorised announcement). On our 73G's a Boeing announcement will automatically play when the masks are deployed. Once the initial descent is complete, the captain will make a PA "initial descent complete", and we will monkey swing (go from spare mask to spare mask) our way to the nearest equipment locker, and go on to our portable oxygen cylinders and offer assitance to injured pax, make sure pax are on oxygen until we are advised by the captain that oxygen is no longer needed. If there is sufficient time before landing, we try to tie up the masks to clear them out of the way in case we need to evacuate. We had a decompression recently, and the report circulated after the event noted that many pax either stared at the mask, put it on without pulling it (which pulls a pin and starts the chemical oxygen generator), or even started wiping them as they were dusty! We even had complaints from pax that the crew were shouting at them, and not offering any help. To all you pax - please listen the safety demo - the crew are instructed to ensure their safety first before assisting passengers.

Very true. A crewmember can't help you if they lose consciousness. One of the things that always gets me is in the safety demo it tells people to put their own masks on before helping others. However, I worry that many parents would worry about their kids first, which could lead to them blacking out before they or even the child/dependant they went to assist in the first place did. I wish there was a way to explain the importance of this to pax without panicking them.

Incredibly, this is something that hasn't changed since the 1970s. The NTSB reported a case back in that era where a decompression on a DC-10 resulted in all but one passenger NOT using their masks; they just stared at them not doing anything. They all had to be assisted by the flight attendants.

An automatic pre-recorded announcement can help in these situations.

I always remind my parents with lap-held children to make sure and put their mask on first as it is imperitive to the childs safety should a decompression occur. It's an extra effort made to make sure that they understand the importance of donning their mask for the safety of their child, and hence it has never panicked any of my PAX. Sometimes I am even thanked for the reminder, or at the very least am told by the PAX that they understand. It is my hope that they see this as me caring for their child's well-being, as well as their's. 14 years and no complaints yet, hope that helps.

Happy Landings,

Jay

While I'm sure it was handled professionally and by the numbers, they should consider themselves lucky that they were able to complain.

What on earth is wrong with people these days that they have to be so rude and ignorant?

"We were descending at 5000FPM, but that girl never came back with my beer".

Cabin Crew are saints. I'm sure there are bad or surly ones up there seeing as they are human and all, but I've never met one on BA, AA, Virgin, PA (I still love you, Vicki - 1st Class on Maid of the Seas in 1997), Lauda, LH...

We're not about respect anymore, are we.  Sad

at QX... It depends what type of aircraft we are working. On our Q400 turboprop there is no cabin oxygen system. The only oxygen in the cabin is in the before mentioned POBs. Should a slow decompression occur, that would be the only time in which we would use a POB, among some other scenarios not related necessarily to this topic. In a rapid decompression we are advised to immediately secure ourselves and prepare for an "Emergency Descent" From 250, an Emergency descent would get us into a 'more' breathable atmosphere extremely quickly. Hence the aircraft is not outfitted with a PAX oxygen system, and doesn't fly in excess of FL 250

Hope that shines some light on a different part of the spectrum!
