Regular inspections

1. The user unit should report for regular inspection to the inspection agency one month before the expiration of the regular inspection validity period. The first regular inspection of storage tanks is generally conducted within three years of their commissioning. Subsequent inspection cycles are determined by the inspection agency based on the safety status level.

2. The user unit and its auxiliary units should carry out technical handling after shutdown and conduct safety inspections prior to testing, ensuring the on-site conditions meet the requirements for the inspection work and prepare accordingly.

During inspections, the unit's safety management personnel, operators, and maintenance staff should be present to assist with the inspection, promptly provide relevant documents, oversee safety, and establish reliable communication methods.

Safety Protection

The potential hazards in the operation of liquefied natural gas primarily stem from its physical properties:

Liquefied natural gas has an extremely low temperature at atmospheric pressure: -162°C.

High gas-liquid volume ratio; improper pressure relief measures can lead to rapid pressure increase. The gas-liquid volume ratio of liquefied natural gas is approximately 620:1.

Natural gas is an asphyxiating gas.

Natural gas is a flammable gas (ignition point 538°C).

Explosions may occur in confined spaces (explosive limits in air: 5.3% to 15%)

2. When working at a site with natural gas or liquefied natural gas, the following safety knowledge is required:

Keep liquefied natural gas equipment away from flames or electric sparks.

No smoking or open flames are permitted in areas involved in Liquefied Natural Gas equipment maintenance, refueling, and storage.

When working in areas with liquefied natural gas, protective goggles, face shields, and insulated gloves must be worn. Pants should not be tucked into boots, sleeves should not be worn inside insulated gloves, and boots should not have nails.

During dismantling and component maintenance, the liquefied natural gas tank must be emptied and depressurized.

Tools used for maintenance should not produce sparks.

3. Warning

Protect eyes and exposed skin.

Maintain good ventilation in the area where the equipment is located.

Ensure the system is depressurized when repairing or maintaining equipment.

Keep away from flammables or electric sparks.

The root valve must be kept constantly open.
