10.1.3.4 Precautions When Using Oxygen

When using a portable oxygen bottle the following precautions should be taken:

(a) As oxygen promotes combustion there is to be no smoking within a 3 metres radius of the passenger using oxygen (approximately 3 passenger rows either side);

(b) Ensure that the oxygen bottle fittings are free from any oil or grease as such contaminants can cause combustion;

(c) Turn the ON/OFF valve slowly and do not over tighten when closing;

(d) Before putting on the mask wipe away any heavy lipstick or grease from the mouth area;

(e) Ensure tubing is not kinked and that oxygen is flowing (filling of re- breather bag) before fitting the mask with an efficient seal to the passenger's face. Some oxygen masks are fitted with a ‘green indicator flow valve’. When oxygen is flowing to the mask, the indicator (normally clear or sometimes red) will turn green;

(f) If it is necessary to use a portable oxygen mask on an infant, reverse the mask (nose part under the chin) and hold gently against the face. The re-breather bag should be held vertically to ensure the free flow of oxygen;

(g) Oxygen therapy is rarely detrimental to a patient and its value far outweighs the very rare problems caused by its use. The passenger will normally be able to advise the position in which he/she breathes easiest. If required and available, cabin crew should seek assistance from a medically qualified passenger(s); and

(h) When the pressure gauge indicates less than 200 psi the valve should be turned off and the bottle considered empty.

Rev 11 19 Dec 06 10.1.5 HALON Fire Extinguisher (Type 1)

10.1.5.1 General

This type of fire extinguisher is designed for extinguishing electrical and flammable liquid fires and is suitable for ALL types of fires in an aircraft. The extinguishing agent is a vaporising liquid that interrupts the chemical reaction taking place in the flames thereby extinguishing the fire. It is a colourless, non-corrosive liquefied gas that can give off an acrid odour that can cause running of the eyes and nose.

10.1.5.2 Pre-Flight Check

(a) Check that the pressure indicator is positioned in the green range indicating acceptable pressure charge; and

(b) That the ring pin is in place with the seal intact.

Note: The extinguisher is serviceable even if the plastic seal of the ring pin is broken, provided that the pressure gauge is in the green band.

10.1.5.3 Operation

(a) Remove from bracket;

(b) Remove ringed safety pin from the lever and handle;

(c) Hold the extinguisher upright with the fingers of one hand under the handle and the thumb on the top of the lever. The other hand should be placed on the bottom of the bottle to steady it if necessary; and

(d) Aim the extinguisher at the base of the fire and press the lever down with the thumb.

Note: Duration of discharge from the small size bottle is approximately six (6) seconds and twelve (12) seconds from the large size bottle. 10.1.5.4 Precautions

(a) Do not discharge directly at a person;

(b) Discharge distance should be between 1.5 and 2 metres with an open fire in the cabin. In the case of a fire in a confined space the extinguisher should be held as close as possible.

The extinguishing agent has the same properties as the HALON fire extinguisher (Type 1) above.

10.1.6.2 Pre-Flight Check

Check the red indicator disc is in place and that the sealing wire is intact. Note: If the red disc or sealing wire are missing the weight of the extinguisher should be compared with a serviceable bottle to determine if the contents are still intact. If not, the extinguisher must be replaced. 10.1.6.3 Operation

(a) Remove from bracket;

(b) Raise safety catch on the back of the operating head by pushing up with the thumb;

(c) Grasp the operating handle and put the forefinger through the loop provided at the same time firmly pressing the trigger at the back of the handle with the heel of the hand;

(d) Initial depression of the trigger will cause the red disc to fall out and a little additional effort is required to break the sealing disc of the extinguisher;

(e) Hold extinguisher at an angle within 600 _{of vertical position;}

(f) Firmly squeeze the actuation trigger; and

(g) Ensure that the discharge nozzle head is pointing toward the fire before operating.

Note: Duration of discharge is approximately thirteen (13) seconds. 10.1.6.4 Precautions

(a) Do not discharge directly at a person;

(b) Discharge distance should be between 1.5 and 2 metres with an open fire in the cabin. In the case of a fire in a confined space the extinguisher should be held as close as possible.

Rev 11 19 Dec 06 10.1.7 Protective Breathing Equipment (PBE)

10.1.7.1 General

Protective breathing equipment (PBE) is a breathing apparatus designed to protect the wearer's eyes and respiratory tract from the effects of smoke and toxic fumes while fighting an in-flight fire.

The following general features apply to all types of PBE’s installed on Company aircraft:

(a) They are designed to enclose the head within an elastic neck seal and provide for a minimum of 15 – 20 minutes (depending upon the manufacturer) of breathable air from a chemical generator;

(b) They can be worn by persons with glasses, jewellery, a beard or a hair bun;

(c) They are installed with a neck shield (of varying length depending upon manufacturer) that extends downward from the hood to protect the collar and upper shoulder area; and

(d) They have features that permit the wearer’s voice to be heard outside the PBE.

Note: Excess make-up should be removed before donning a PBE as contact between grease and oxygen can cause burns.

Wearer’s should be aware that although the head area is protected, the rest of the body is not and the wearer should guard against a feeling of invincibility.

Company aircraft are installed with one of three types of protective breathing equipment as detailed below.

10.1.7.2 Puritan Bennett PBE

This PBE is a demand device which means that more strenuous the work the more oxygen will be produced.

(a) Pre-Flight Check:

(i) Inspect that the PBE unit is visible through access door; (ii) Confirm that the white tamper proof seals located at the

top and bottom of the access door are intact; and (iii) Ensure that the foil pouch is in place and is not obviously

expanded.

(b) Operation:

(i) Open the container by pulling the red handle. Pull the red tag to open the foil pouch and pull out on the blue aural/nasal cone and remove the hood;

(ii) Place both hands inside the neck seals, palms facing each other and visor facing downward. Guide the hood over the head and down over the face using the hands to shield the face and glasses from the blue cone ensuring that hair clothing and jewellery is clear of the neck seal; (iii) Using both hands pull the neck shield down over the

collar and shoulders; and

(iv) Grasp both adjustment straps at the lower corner of the visor and pull forward simultaneously to activate the oxygen canister, then backward to seal the cone over the nose and mouth. Oxygen will inflate the hood.

(v) If required, adjust glasses through the fabric, not through the neck seal.

Note: The blue cone must be positioned high on the nose with a firm seal otherwise fogging may occur. If the hood begins to deflate and becomes hot and moist the oxygen supply is depleted and the PBE must be removed.

A320/321 STANDARD OPERATING PROCEDURES EMERGENCY EQUIPMENT Rev 11 19 Dec 06 (c) Abnormal Operation

(i) Failure of Starter Candle

If the starter candle fails to activate when the adjustment strap is pulled an additional sharp pull on the strap may be adequate to actuate the device. If the device still fails the hood will continue to function. Placing fingers into the neck seal may be required to enable sufficient breathing volume until the chemical generator begins supplying oxygen.

(ii) Loss of Neck Seal

The continued presence of strong irritating odours inside the hood that results in eye and respiratory tract discomfort is an indication of an ineffective neck seal. Ensure that the neck seal is in contact with the skin and that the seal is not disrupted by hair or jewellery. If the condition persists or there is evidence of a tear in the neck seal, the wearer should quickly go to a safe area and remove the hood and don an alternative unit.

(d) Removal

(i) Move away from fire and/or toxic fumes area;

(ii) Push adjustment buckles forward with thumbs to release straps;

(iii) Place both hands under neck seal and ease up over face; (iv) Stow PBE in a safe dry place and allow it to cool; and (v) Brush hair with hands to break down any oxygen build up.

A320/321 STANDARD OPERATING PROCEDURES EMERGENCY EQUIPMENT Rev 11 19 Dec 06 10.1.7.3 Drager PBE

The oxygen canister can be activated by just breathing into the oral-nasal mask but to start the chemical reaction by this method takes a few seconds, therefore pulling the black quick-start toggle is the more immediate method of activation.

(a) Pre-Flight Check:

(i) Check container seal is intact and the yellow serviceability indicator is not broken; and

(ii) The container is not broken.

(b) Operation:

(i) Open container and remove foil bag containing the hood; (ii) Pull red tear strip at top of foil bag and remove hood; (iii) Place hood over head ensuring that the breathing bag

cover is to the front over the chest;

(iv) Ensure that the neck seal is free of obstruction (e.g. hair, clothes collar, etc) and that the head harness is pulled down for a secure fit;

(v) Fit oral-nasal mask securely to the nose and mouth and pull black quick start toggle to activate; and

(vi) Fit tie strap around the waist.

(c) Abnormal Operations:

If the hood collapses onto the head during inhalation or there is an increased breathing resistance check the fitting of the oral-nasal mask as the cause may be an incomplete respiration back to the breathing back due to leakage or an empty oxygen source.

After correcting the fitment of the oral-mask check the equipment by making five (5) deep breaths. If the collapsing of the hood or increased resistance occurs again either the oxygen reserve has been used up or the hood is defective and should be removed.

A320/321 STANDARD OPERATING PROCEDURES EMERGENCY EQUIPMENT Rev 11 19 Dec 06 (d) Removal:

(i) Move away from fire and/or toxic fumes area; (ii) Release the tie strap;

(iii) Place both hands under neck seal and ease up over face; (iv) Stow PBE in a safe dry place and allow it to cool; and (v) Brush hair with hands to break down any oxygen build up.
