insulated.
5．Check electrical equipment regularly. Failure should be corrected immediately, such
as loose connection or charred cable.
6．A second person must be present in order to control the emergency stop button
or power switch in case of emergency when operating an electrified part. The
working area should be isolated with red and white barrier belt and warning signs.
7．Be sure to use insulating tools.
2.10 Gas supply
Gas leaked from the gas supply system can cause an explosion once being exposed to
oxygen and fire. Please ensure that the gas supply pipe is connected correctly.
The room should be ventilated per shift when the circulating air is used. Prevent the
accumulation of air in the enclosed area.
Choose a fire extinguisher that is suitable for the combustibles in the room. Indicate

10 / 49
the location of the fire extinguisher and the escape route.
Conduct the regular vacuum leak testing. Leave the room immediately if a significant
leakage accident or equipment failure is found; breathing apparatus must be worn when
re-entering the room. In this case, at least two people must be present.
The gas container must be stored far away from open fire and heat source (> 50°C). The
direct sunlight should be prevented if the gas containers are kept outside.
Gas container must be equipped with a safety helmet during transportation. The gas
container should be tightened to prevent falling. The gas container should be prevented
from leakage during storage and usage. Gas containers should be kept in a well-ventilated
area away from the flammable. It shall not be stored along the escape route or in the
working area and adjacent areas. Do not store the gas containers in the storage room. Only
the original gas container supplied by the manufacturer can be used. The valve on the
container should be checked for air leaks when replacing gas container. The safety valve
shall not be adjusted. The gas should not be released in the enclosed space.
The repair must be operated by professionals. Protective clothing and gloves made
of leather or thick material should be worn. If the gas escapes into the enclosed space, an
independent breathing apparatus should be worn.
Comply with other national regulations (for example, vehicle labels in the transport
process), and conduct regular personnel training, etc.
Comply with the country's regulations on the permit and test cycle of the gas
container.
2.10.1 Nitrogen (N2)
Chemical and physical properties and instructions for use.
Only at room temperature can nitrogen react with a few substances, such as lithium
and calcium to generate nitrides. The nitrogen is not prone to reaction with others even
at high temperatures. So, it is used as an inert gas and for technical process, transportation
and storing flammable liquids.
Warning in case of fire or accident
The nitrogen is un-inflammable. The fire hazard may cause the increase of pressure
and explosion of the gas container. In case of fire, the water spray, gas or powder fire
extinguisher should be used. If the gas escapes, do not spill water on the gas container.
Use cold water to fully cool the surrounding containers and gas container. The cold fog
heavier than the air is formed when a large amount of escaping gas mixes with the damp
air. Wear independent breathing apparatus and protective clothing to protect the whole
body. The nitrogen does not cause water pollution.
Health precautions
Utility and toxicity: the nitrogen does not cause the physiological effect, but cause
breathing difficulties and even suffocation when the concentration exceeds 88%. It doesn't
cause restlessness or warning symptoms.
Emergency
If inhaling the nitrogen, the victim must be evacuated from the danger zone and
provided with plenty of fresh air. In enclosed spaces, the first-aid personnel must wear

11 / 49
independent breathing apparatus. Victims need rest, warmth and even artificial
respiration. Keep the respiratory tract unimpeded, monitor the blood circulation, and
perform heart massage if necessary. If being unconscious, the patient should be kept in a
lateral position when being placed or moved, waiting for the diagnosis of doctor.
2.10.2 Oxygen (O2)
Chemical and physical properties and instructions for use.
Though being un-flammable, the oxygen can contribute to the combustion. Although
the oxygen is 11% heavier than the air under the environmental temperature, the
concentration of the oxygen close to the ground will not increase as the air does not
separate. The temperature of the liquid oxygen is very low (-183 °C under the
atmospheric pressure). The skin will be damaged by the "cold burning" phenomenon
quickly if being contacted with the oxygen at such temperature. Some materials will be
likely to become fragile under low temperatures.
Warning in case of fire or accident
The increase of oxygen content in the air will significantly increase the fire risk (even
if increased by a very low percentage). Materials which are nonflammable in air (including
insulated flame-resistant materials) will burn fiercely or even cause spontaneous
combustion in oxygen-enriched air. In such condition, flame temperature will be higher
and the fire will spread quickly.
Health precautions
The volume ratio of oxygen in air is 21% under the natural condition. Therefore,
oxygen escaping into the air will not incur pollution. In most cases, harmful effects will not
be caused to the human body if pure oxygen or air with high oxygen content is inhaled.
Good ventilation should be guaranteed for clothes to be dressed in environments with
possibly high oxygen content. Oxygen shows a strong adsorption capacity to clothes. Fire
sources including cigarettes may fire the clothes. Low-temperature liquid oxygen will not
pollute the floor when it spills by accident, because it will evaporate instead of penetrating
into the ground, or will penetrate in a small volume at most. Temporary local freezing of
the ground will not cause any continued damage.
2.10.3 Compressed air
General safety pre-warning
1．Operators should follow safe operating mode and all relevant local occupational
safety regulations and rules.
2．If the following instructions are inconsistent with relevant local regulations, the
stricter one’s hall prevail.

12 / 49
3．Installation, operation, maintenance and repair should be conducted by skilled
personnel authorized and properly trained only.
4．The air generated by the compressor is not the air can be inhaled. The compressed air
must be filtered in accordance with local laws and standards to generate the air can
be inhaled.
5．The compressor should be stopped before performing any maintenance, repair and
adjustment or any other routine inspections, so press the Emergency Stop button,
power off and decompress the compressor. Then turn off the circuit breaker and fix it
on the OFF position.
Do not fiddle with compressed air. Do not blow directly to the skin or toward a third party
with compressed air flow. It is strictly prohibited to remove dust from the surface of
clothes with compressed air. Always maintain heightened alertness when using
compressed air to clean the equipment, and wear protective glasses.
2.11 Refer to safety standards
Laser processing equipment and operations shall be in accordance with both two national
standards, which are GB7247-87 Radiation safety of laser products, equipment classification,
requirements and user guide, and GB10320-88 electrical safety of laser equipment and facilities.
