10.8.2 Air Line Breathing Apparatus
่อการศึกษาเท่านั้น---
Air line breathing apparatus enables compressed air equipment to be
used for longer periods than would be possible using self-contained
equipment.
emergency supply of air cylinders for use in the event of the compressorย์นาวี
This equipment consists of a face mask which is supplied with air through
a small diameter hose leading outside the space where it is connected to
either compressed air cylinders or an air line served by a compressor. If
the ship’s air supply is used, it is essential that it is properly filtered and
adequately monitored for toxic or hazardous constituents. The hose is
attached to the user by means of a belt or other arrangement, which
enables rapid disconnection in an emergency. Air to the face mask is
regulated by a flow control valve or orifice.

If the air supply is from a compressor, the arrangement will include an

failing. In such an emergency, the user should be signalled to vacate the
space immediately.

A trained and competent person must be in control of the air line
pressure and be alert to the need to change over to the alternative supply
should normal working pressure not be maintained.

When using the air line breathing apparatus:
ึ
Check and ensure that the face mask is adjusted to be airtight. The
presence of facial hair may make this task harder to achieve.
Check the working pressure before each use.

Check the audible low pressure alarm before each use.
---ใช้เพื
To avoid damage, keep the air lines clear of sharp projections.
Ensure that the air hose does not exceed 90 metres in length.

Allow ample time to vacate the space when the low pressure alarm
sounds. The duration of the emergency air carried by the user will
depend on an individual’s weight, fitness and level of exertion, and
each user should be aware of their particular limitations.

Should there be any doubt about the efficiency of the equipment, the user
should vacate the space immediately.

The user should carry a completely separate supply of clean air for use in
emergency evacuation from the space in the event of the air line failing. It
is recommended that the user should carry an Emergency Escape
Breathing Device (EEBD) (see 10.8.3 below).

10.8.3 Emergency Escape Breathing Device (EEBD)

This is a compressed air or oxygen breathing device used for escape
from a compartment where the atmosphere has become hazardous while
a person is within it. It is primarily for use in accordance with the SOLAS
requirements for escape from machinery or accommodation spaces in the
event of a fire. Additional sets should be provided for use as emergency
escape equipment during enclosed space entry. Each set has a duration
of not less than 10 minutes. The device can be one of two types:
Compressed Air Type
These sets consist of an air bottle, reducing valve, air hose, face mask or
