1. Introduction

1.1 General Description of the product

1.2 Getting familiar with the equipment - Short Description

The new LALIZAS Respiratory Protective Device (of types 71327 & 71328) is a Self-contained open-circuit compressed air breathing apparatus with positive pressure full face mask. It is

an Apparatus for fire-fighting of Type 2 tested according to EN 137 (2006) and EN 136 (1998) including AC (1999) and AC (2003), ISO 23269-2:2011.Certified according latest provisions

of MED Directive 2014/90 and SOLAS requirements.

Approved for use as self-contained compressed air breathing apparatus of fire-fighter's outfit.

The apparatus is not for use in accidents with cargoes.

WARNING:

- It is not a diving apparatus!

- It is strongly recommended that the Apparatus is used by well- trained personnel and not by untrained users.

The Lalizas Self-Contained Breathing Apparatus Models (71327 & 71328) are similar products, as their main structure and operation is the same, while the only difference is in the used

cylinders providing different rated duration to the products. The Breathing Apparatus is sufficiently robust to withstand the rough usage it is likely to receive, and is designed so as to have

no protruding parts or sharp edges likely to be caught on projections in narrow passages or to be in contact with the wearer. It is designed to ensure its function in any orientation. All

materials used in the construction of the apparatus have adequate resistance to deterioration by heat and adequate mechanical strength. All demountable connections are readily

connected and secured by hand.

The product consists of six main components as described in short below:

a) Back frame: Incorporates donning cushion harness for convenient fitting, adjustable cylinder holding Velcro webbing and a rubber pad for better and stable placement of cylinder. It is

designed to allow the user to don and doff the apparatus quickly and easily without assistance and is adjustable, without slipping inadvertently. The back frame structure bears two grooves

for the high and medium pressure hoses of the pressure regulator to run in (Figure 1).

b) First Stage Regulator: The first stage regulator incorporates two pneumatic hoses, a reliable pressure indicator and a warning whistle. The pressure indicator, which is positioned to

enable to be read conveniently by wearer, shows the pressure in the pressure vessel on opening the valve, to ensure that the pressure is monitored. The Pressure Indicator is graduated

from zero mark up to 40Mpa (400Bar) and enables the wearer to estimate the pressure to within 1Mpa(10bar). It bears a fluorescent dial that allows clear reading of the pressure even in

intense dark, and a non-splintering window. The Warning Whistle is so designed that when pressure reduces below 50-60bar, it operates providing a continuous sound of pressure

level>90dB (A), warning the user that the air is dropping down. Moreover, the First Stage Regulator bears a connecting thread for the cylinder valve, which is G5/8 according to EN144-2.

For increased safety a relief valve is also incorporated (Figure 2).

c) Second Stage Regulator: The second stage regulator consists of an “on demand'' valve and a pneumatic hose (Figure 3 ). The pneumatic hose is equipped with a fast joint for easy

assembly with the first stage regulator hose. The “on demand'' valve is so designed that can be assembled with the face piece as a plug-in interface (Figure 3). The ''on demand'' valve is

equipped with ON & OFF buttons in order to allow the user to stop or start the air supply. Using these buttons the user can stop the air supply and remove the valve from the face piece while

the cylinder valve is still open (Figure 1). This special structure does not allow the provided breathing-air to escape, while it provides the user with the possibility to re-attach the “on

demand valve” to the face piece –at all times- and re-use the device without any special procedure except just breathing. Breathing will produce under pressure inside the face mask that

will force the on ''demand'' valve to open and provide breathing air again.

d) Face piece (Figure 4): The face piece is classified as Mask of Class 3+ for Special Use per EN 136:1998 + AC (2003) and as instructed in the last version of Maritime Equipment

Directive 96/98/EC. The mask is temperature, flammability and thermal radiation resistant as well as it is leak tight and consists of:

for the design & construction of refillable transportable seamless aluminium and aluminium alloy gas cylinders of capacity from 0.5 litre up to 150 litre” & EN 12245 “Transportable gas

cylinders- Fully wrapped composite cylinders” and certified under Pressure Equipment Directive (PED) 97/23/EC as amended, is used. The pressure vessel outlet connection is designed

per EN 144-1 i.e. the Cylinder thread for both models is 18x1, 5mm.

Both types of cylinders are coloured per the Colour Coding System as instructed for breathing air by EN 1089-3:2001 “Transportable gas cylinders- Gas Cylinder Identification (excluding

LPG)- Part 3: Colour Coding.”

f) Pressure Vessel Valve (Figure 1): The cylinder valve that is used for both Self-Contained Breathing Apparatus Models (71327 & 71328), is designed in accordance with EN 144-1

“Respiratory Protective Devices- Gas Cylinder Valves- Thread Connections for Inlet Connector” and EN 144-2 “Respiratory Protective Devices- Gas Cylinder Valves-Outlet Connections”.

More specifically, the inlet and outlet connections on the pressure vessel valve are respectively in accordance with the requirements given in EN 144-1 for the inlet connection (M18X 1,

5mm) and EN 144-2 for the outlet connection (G5/8). This valve has a Working Pressure of 30MPa, while it bears a relief valve. The cylinder valve is equipped with a convenient in use

rubber knob and is so arranged that the wearer can operate it while wearing the apparatus. It is also protected against blockage and transmission of particulate matter that may be

contained in the compressed air and is so designed that the valve spindle cannot be completely unscrewed from the assembly during normal operation.

The LALIZAS Self-Contained Breathing Apparatus Models (71327 & 71328) are packed in heavy duty plastic carrying suitcases which provide high impact resistance that protects the

product in case of shock and drop (Figure 5). However, it is recommended to handle them with care.

a. A visor (designed to provide a wide field of vision, to be attached in a reliable and gas-tight manner to the faceblank and to be resistant to scratching and mist covering),

b. A speech diaphragm (protected against mechanical damage),

c. An exhalation valve (that works well in all orientations and is protected against dirt and mechanical damage),

d. A plug-in interface for the insertion of the “on demand” valve (readily connected and secured by hand and not possible to be connected to a thread, assuring correct and reliable

connection between the facepiece and other parts of the equipment),

e. Rubber straps (designed so that the full face mask can be donned and removed easily, while they are adjustable so as to hold the full face mask firmly and comfortably in position),

f. A sealing edge (that in combination with the high quality rubber straps ensure high fitting/ sealing regardless the face structure. It is unlikely that the requirements for leakage will be

achieved if facial hair or spectacle side arms pas under facial seal!)

g. A head net.

All components which are integral with the face mask, are of high quality and ergonomic design so as to serve in the best way a combination of well-fitting and easy-use of the device. Care

has been taken so that materials that may come in contact with the wearer's skin are not likely to cause irritation or have any adverse effect to health.

1.3 Structure of the Product

The Self-Contained Breathing Apparatus is a light weight (71327 Model has a weight of 15kg & 71328 has a weight of 12kg) and highly comfortable apparatus that can provide respiratory

protection to the wearer for approximately (71327 Model: 45min & 71328 Model: 60min) in a hazardous environment. The given duration has been estimated based on an average

consumption of 40L/min and fully charged cylinder (Refer to Para. 1.4 Apparatus Duration).

The Self-Contained Breathing Apparatus (71327 & 71328) is composed of an anatomic back frame with harness for perfect and easy donning. Both back frame and harness are flame

retardant, waterproof and antistatic.

In both cases, the cylinder is connected to the back frame with a cylinder valve, designed according to EN 144-1 and a working pressure of 300bar. The cylinder valve is equipped with a

relief valve. It is connected to a first stage regulator which will decrease the high pressure of 300bar to a constant Pressure of ≈7bar and a flow of >350L/min. The first stage regulator is

also equipped with a relief valve that will open when the air pressure becomes greater than 11bar. From the first stage regulator the air is diverted into two tubes one of high pressure (WP

300Bar) and one of medium pressure (WP 20Bar). The high pressure tube – which is mounted within a tube of medium pressure for protection reasons – is attached to a warning whistle

and a pressure gauge. This tube is under the exact pressure of the cylinder when the cylinder's valve is open. The warning whistle is so designed that when pressure reduces below 50-

60bar, it operates providing a continuous sound of sound pressure level of >90dB (A), warning the user that the air is dropping down. The medium pressure tube is under pressure of 7bar

and is connected via a fast joint to the second stage regulator (“on demand'' valve) and the full face mask. The joint of the second stage regulator to the face mask provides a capability of

rotation by 360º for easier connection and more comfortable fitting. A plug-in interface is used to connect the “on demand” valve to the face mask.

1.4 Apparatus Duration

The working duration of 45min and 60min of the Self-Contained Apparatus 71327 and 71328 respectively was estimated for an average breathing air consumption of 40L/min in ambient

temperature and fully charged cylinders. However, the actual consumption might vary due to the following affecting factors:

a) Workload: Adverse work conditions can cause increase of breathing rate and as a result increase of consumption.

b) Physical fitness of the wearer: A bad physical fitness of the wearer can affect/ increase the air consumption.

c) Inconvenience in movement: Heavy and restrictive clothing demand bigger effort in movement and this would lead to increased air consumption.

d) Emotional stress and fatigue can also affect the duration of the devices.

1.5 Air quality of the equipment

The quality of breathing air used for filling the Self-Contained Breathing Apparatus conforms to EN 12021- “Respiratory protective devices - Compressed Air for breathing apparatus”. The

concentration limits of the breathing air components are described in the table below:

Figure 7 Closing the air supply by the ''OFF'' button of the second stage regulator

d) Open the Cylinder Valve until you hear the whistle sound and see the gauge indication stabilizing (Figure 1 & Figure 8). The indication must always be equal or more than 80% of

the rated filling pressure (300bar),so be between 240-300bar. The indication might vary ±10% depending on the environmental Temperature. Close the Cylinder Valve. Keep

checking the pressure gauge for 60 sec. If after 60sec the pressure drop is less or equal to 20dar, this means that the whole system is leak-tight. If the pressure drop in 60sec is more

than 20bar, send the SCBA for service to a LALIZAS authorized Service Station.

Figure 8 Opening the cylinder valve

e) After checking leak-tightness bring the Second Stage Regulator in mouth and inhale to check the operability of the “on demand'' valve (Figure 9). After inhaling the air pressure

will drop causing the whistle to sound again. Check the pressure gauge indication to be approximately 50 bar when the whistle sounds (Figure 9).
