Warning Notice | High Temperature + Flood Season! Key Points for Special Equipment Safety Risk Prevention!

All special equipment units should, according to the dual prevention system requirements for special equipment safety risk control and hidden danger investigation and management, and based on relevant special equipment safety technical specifications and standards, user manuals, design drawings, etc., quickly inspect potential safety hazards under extreme weather during the flood season, and implement all safety precaution measures.

Special equipment risk points

Continuous high temperature weather causes special equipment downtime

High temperature and heavy rain risk points

❖ Geological landslides and foundation settlement may cause equipment displacement, deformation, and cracking.

Safety precaution measures

❖ When storage tanks of liquefied gas media experience over-temperature and over-pressure, decisive measures such as spray cooling and forced ventilation should be taken.

❖ Strictly control the liquid level of liquefied gas storage tanks.

❖ Transportation and storage of gas cylinders should avoid exposure to intense sunlight; they should be stored in shaded areas and cooled if necessary.

❖ Necessary foundation reinforcement should be carried out in soft soil and quicksand areas.

High temperature and heavy rain risk points

❖ Pipelines carrying liquefied gas media may experience over-temperature and over-pressure phenomena, potentially leading to explosions.

❖ Pressure pipelines may expand due to temperature rise, causing safety hazards such as misalignment of supports and hangers and increased thermal stress.

❖ Geological landslides and foundation settlement may cause buried pipelines to float, supports to be destroyed, deformed, or displaced, leading to pipeline instability and cracking.

Safety precaution measures

❖ Monitor pressure and temperature parameters of pressure pipelines to ensure they remain within normal controllable ranges.

❖ Install pressure pipelines strictly according to standards, ensuring flexibility and sufficient expansion allowance.

❖ Observe the geographical environment of buried pipelines and take measures such as fixing pressure pipelines and building cofferdams to prevent water erosion when necessary.

Elevator equipment

High temperature and heavy rain risk points

❖ Some elevator machine rooms, shafts, or pits have unreliable rain and waterproof facilities, and sudden heavy rain may flood these areas causing moisture or short circuits in some electrical devices.

❖ Flooding can cause mechanical parts to be soaked or rusted, and lightning may cause urban power system failures, all potentially causing sudden elevator malfunctions and stoppages.

❖ Some elevator machine rooms exposed to intense sunlight may have control system motherboards and other electrical components fail or activate overheating protection devices, causing elevator stoppage.

Safety precaution measures

❖ Strengthen safety education for operators to prevent heatstroke and electric shock.

❖ Improve disaster prevention hardware, reinforce foundations around elevator equipment, and add flood and lightning protection facilities.

❖ Improve rain protection and cooling facilities in elevator machine rooms, add dedicated sump pumps for elevator pits, and adjust elevator standby floors to above the second floor in advance.

❖ Conduct timely hazard remediation on key parts such as elevator electrical circuits, safety devices and accessories, and emergency cut-off devices to eliminate safety hazards promptly.

High temperature and heavy rain risk points

❖ High temperatures cause equipment hydraulic system failures.

❖ High temperatures reduce the viscosity of lubricating oil, decreasing lubrication effectiveness and accelerating wear of main crane components.

❖ During floods caused by heavy rain, outdoor cranes soaked for long periods may suffer electrical equipment damage or failure due to water ingress.

❖ Heavy rain reduces visibility, increasing the risk of accidents causing injury or death to operators.

❖ Heavy rain may trigger mountain floods and debris flows, impacting cranes and track foundations, causing crane overturning and track foundation damage.

Safety precaution measures

❖ Pay attention to cooling the hydraulic system oil to prevent sun exposure; replace lubricating oil and hydraulic oil that meet operational environment requirements.

❖ Regularly inspect and promptly replace major worn parts.

❖ Outdoor crane track foundations must have sufficient strength to prevent heavy rain from washing away the foundation and causing crane collapse.

❖ Before flood season and extreme weather, proactively check the performance of anchoring devices, rail clamps, and rail shoes for wind resistance and anti-slip functions to ensure normal operation. Regularly check to keep crane tracks or cable trenches well-drained; ensure electrical rooms (or electrical control cabinets) do not leak water.

❖ According to weather warnings, reasonably arrange work tasks and prepare windproof measures for outdoor lifting machinery in advance. Operators must strictly follow the "Ten No-Lifting" rules; operations must stop when wind force exceeds level 6 or during heavy rain.

High temperature and heavy rain risk points

❖ High temperatures cause hydraulic oil viscosity to decrease, poor sealing, and excessive temperature rise.

❖ High temperatures cause poor equipment heat dissipation, triggering fault alarms and electrical component overheating failure.

❖ Electrical system, electrical safety devices, motor seals, and other components fail due to water ingress, causing electrical short circuits.

Safety precaution measures

❖ Check the cooling system and regularly monitor oil pressure.

❖ Install heat dissipation or cooling systems to ensure normal system operation.

❖ Add waterproof walls in low-lying areas, increase drainage facilities, insulate equipment prone to water immersion to prevent water ingress.

❖ Pay attention to heavy rain, strong wind, and other severe weather warnings; strengthen emergency patrols and inspections promptly, identify safety hazards, and ensure equipment is waterproof, moisture-proof, and heat-resistant to avoid damage to special equipment and ensure safe operation. Outdoor work and operations should stop during severe weather. Check equipment foundations and clear drainage facilities to ensure smooth drainage. Outdoor elevators should be stopped.
