INTRODUCTION

This User Manual (hereinafter referred to as «Manual») is intended to study the design and the

rules for use of the closed-circuit compressed-oxygen self-contained breathing apparatus P-30EX

(hereinafter referred to as the «breathing apparatus»). It also contains instructions for the proper use

of the breathing apparatus.

The Manual describes the principles of operation, design, rules for preparation of the

breathing apparatus for work as well as a quick procedure for technical condition check and

recommendations for maintenance of the breathing apparatus.

The Manual uses a series of symbols to draw the user’s attention to features, problems, and

dangerous situations as may be encountered in the course of the use and maintenance of the

breathing apparatus.

NOTE!

This symbol indicates additional information about the rules, methods, and recommendations for correct

use of the breathing apparatus.

CAUTION!

This symbol indicates a dangerous situation that, if not eliminated, could result in equipment damage,

injury, or even death of the user or a member of the maintenance personnel.

DANGEROUS!

This symbol indicates an inevitable dangerous situation that, if not eliminated, can lead to a serious

injury or death of the user.

1. ACCIDENT PREVENTION REGULATIONS

1.1. Safety rules and rules of use

When using the breathing apparatus, the requirements speciﬁed in this manual must be observed.

In particular, it is necessary to read and take into account the safety rules and information on the

breathing apparatus use and operation. National regulations and legislation in the country, where the

breathing apparatus is used, also should be taken into account. The breathing apparatus must only

be used for the purposes speciﬁed herein.

The breathing apparatus must be regularly inspected and serviced by qualiﬁed personnel. Repairs

and regular maintenance of the breathing apparatus may only be performed by service centers

authorized by the manufacturer. Information on the frequency and scope of regulatory work see

Section 7. Breathing Apparatus Maintenance

NOTE!

Breathing apparatuses must be used and maintained by persons who have the appropriate

qualiﬁcations. The breathing apparatus must undergo complete disassembly and maintenance

(in accordance with the annual breathing apparatus revision instructions which are only available to

authorized DEZEGA service centers) on a yearly basis.

Only original spare parts must be used for the repair and maintenance of the breathing apparatus.

You may order a catalogue of breathing apparatus parts

and components from your local dealer of ТМ DEZEGA

or download it from the website www.dezega.com

DANGEROUS!

The breathing apparatus is not intended for operation under water. Attempts to use the breathing

apparatus under water may result in serious injury or death.

In the case of short-term accidental immersion of the breathing apparatus into the water (for up

to 15 seconds) with a ﬁlled breathing bag and without the lung demand valve operation, lighter

inhalation and an increased exhalation breathing resistance is observed. In the case the lung demand

valve trips after the completion of the inhalation phase, the apparatus continues to supply oxygen

to the breathing bag and to the atmosphere through the relief valve.

When immersing a breathing apparatus in water, observe the following rules:

• try to preserve the horizontal position of the breathing apparatus;

• try to have a full breathing bag and, if possible, avoid deep breaths, which may lead to the

lung demand valve tripping;

• if the lung demand valve trips, make a sharp exhalation to stop the oxygen supply and, upon

removal of the breathing apparatus from water, make 2-3 sharp exhalations.

The breathing apparatus supplies a gas mixture for breathing at a nominal working duration

(hereinafter referred to as the «NWD») for 4 hours and insulates the user from the surrounding

atmosphere that may be contaminated or lacking oxygen for breathing.

Р-30ЕХ (EN 145:1997+A1:2000) | (PPE Regulation 2016/425/EU: Category III) DEZEGA

The use of the breathing apparatus is only allowed under the following conditions:

• the user has passed special training and is allowed to work using the breathing apparatus

according to medical indications as established;

• the oxygen cylinder is filled with oxygen up to the operating pressure;

• the absorbent cartridge is filled with absorber;

• a water ice cube is used as a cooling element at ambient temperature above +26 °C;

• the breathing apparatus is regularly serviced and checked in accordance with this Manual

and has no deviations from the parameters specified herein;

• the breathing apparatus undergoes required maintenance by the user or at an authorized

service center once a year.

Actual NWD for a particular user may differ from the nominal NWD due

to the impact of various factors.

The actual NWD may be aected by:

• physical fitness of the user (poor physical fitness of the user may be the reason of increased

oxygen consumption);

• nature of the work performed (the more actively the users work, the more oxygen they

consume);

• emotional state of the user (an anxious or excited user can consume more oxygen);

• condition of the breathing apparatus (poorly serviced or poorly adjusted breathing

apparatuses may have a leak);

• improperly filled absorbent cartridge;

• cylinder pressure before use (if the cylinder is not filled completely, the working time is

reduced proportionally).

DANGEROUS!

In some cases, the actual NWD of the breathing apparatus may be less than 4 hours. Users who

are unﬁt, stressed-out, of a large build, who work in dicult conditions, as well as uninformed users

or users who do not keep the breathing apparatus in a good condition will spend oxygen much faster.

The nominal and actual NWD are determined by time, in during which the oxygen pressure in the cylinder decreases

up to 1.0 MPa (10 kgf/cm2).

2. PURPOSE, DESIGN AND OPERATION PRINCIPLES

OF THE BREATHING APPARATUS

The breathing apparatus is designed to protect the user’s respiratory system from the harmful eects

of respiration in an IDLH atmosphere during the performance of mine rescue, emergency rescue,

and technical operations in coal mines and other industrial facilities.

The breathing apparatus ensures reliable protection of the human respiratory system in an atmosphere

that contains insucient oxygen or contains toxic gases and coal dust. The breathing apparatus is

designed for operation at an air temperature of -20 °C to +60 °C, relative humidity of up to 100 %

at +40 °C, and atmosphere pressure of 70-125 kPa.

The breathing apparatus is a self-contained device that supplies pure oxygen. The breathing gas

mixture circulates in a closed respiratory circuit. Soda lime CO2absorber absorbs carbon dioxide

contained in a mixture of gases exhaled by the user. In the breathing bag, the gas mixture is enriched

with oxygen from an oxygen cylinder. At low and normal respiration frequency (resting state, walking

at a normal rate), oxygen is supplied to the breathing bag through a constant ﬂow dosing valve. At

an increased breathing frequency, an additional amount of oxygen is fed through the lung demand

valve or the manual bypass valve. The breathing mixture heated by the regeneration reaction passes

through the cooler. In order to reduce the temperature of the inhaled gas mixture (and thereby

minimize the user’s discomfort), as well as during work at an elevated ambient temperature, the

cooling element (a water ice cube) is placed into the cooler of the breathing apparatus. Grinded

ice may be used as a cooling element. The facepiece of the breathing apparatus is represented by

a full-face mask or a mouthpiece with smoke goggles and a headset.

The breathing apparatus is equipped with a signal that trips if the cylinder pressure drops below

5.5 MPa (hereinafter referred to as the «pressure drop signal device»).

The breathing apparatus is also equipped with a device that signals that the cylinder valve is closed

or that there is no oxygen in the system (hereinafter referred to as the «no oxygen signal device»).
