Appropriate area markers should be set up for protected areas and storage areas; areas with the same function but different locations should be marked accordingly. Distinguish by code, such as "Sleep Zone 1", "Sleep Zone 2", and "Sleep Zone 3".

c) Generally, module position markers are placed near the hatches connecting each module and the node module to provide astronauts with directions of travel within the passageway. The location of the reachable compartment is indicated by this sign, which is a combination sign and is usually used in groups; the "-" on the compartment location sign indicates the current compartment. area.

d) Access controls should be installed at the external hatches, module junctions, astronaut transfer paths, the ends of paths, handrails, and foot restraints along the paths. Path markings, including handrails and footrests on external paths, should be sequenced using numerical codes; path markings should have For continuity, multiple signs can be arranged at intervals when needed.

6.2.2 Warning signs The requirements for the use of warning signs on manned spacecraft are as follows:

a) Emergency exit signs shall be installed at the docking hatch of manned spacecraft in accordance with the provisions of

5.5.3 in GB 2894-2025; (b) Continuous emergency directional signs should be installed along the path guiding personnel inside the manned spacecraft to a safe area;

c) In situations that endanger the safety of astronauts and the spacecraft, emergency response measures should be implemented near the areas and products requiring immediate operation. Emergency operation sign;

d) Emergency use signs should be placed near equipment or supplies for emergency use, including astronaut emergency food, repair equipment, and emergency supplies. Life-saving supplies, fire extinguishing equipment, and protective equipment, etc.;

e) On a manned spacecraft, any product that an astronaut might step on, touch, bump into, or look directly at could be damaged or cause injury to the astronaut. Appropriate prohibition signs should be set up in all locations to remind astronauts to pay attention.

6.3.1 Identity Information Markers The requirements for using identification information tags on instruments and equipment are as follows:

a) All instruments and equipment products should be marked with a diamond-shaped symbol to indicate the main information of the product;

b) All instruments and equipment that require astronaut monitoring and operation should have Chinese labels.

c) Instruments and equipment that use electronic management of information shall meet the labeling requirements of 6.10.

6.3.2 Positioning and Orientation Markers The requirements for the use of positioning and orientation markers for instruments and equipment are as follows:

a) All equipment in gas-liquid-fluid circuits through which fluids flow, such as pumps, fans, filters, heat exchangers, and regulating valves, should be equipped with flow direction indicators and inlet/outlet markings. Exit signs and main bypass signs;

b) When using main and bypass signs for marking, branches with large fluid flow should be marked as main routes, and the rest as bypass routes.
