Emergency Rescue & Disaster-Recovery Access

Post-disaster surfaces may not see the foundations, well covers, ditches, underground holes and sharp fragments that have been washed out.The vehicle would fall or damage tyres directly, and the sheeting would not provide reliable support if it were laid in a suspended area.The advance party shall, to the extent permitted by security, inspect the route, mark the depth of the water, the edges, the underground facility and the suspicious hole, and remove the hard matter that will pierce or top the plate.It could be piloted in the light vehicle segment and gradually released.The inspection should focus on the underwater flow of the plate, the slurry out and the sudden deposition, and any anomalies would require immediate closure of the paragraph and re-routing.The treatment of the “ground covered by water, sediment or debris, which is difficult to determine” cannot be limited to one successful pass, but also covers the maximum load, maximum frequency, worst weather and evacuation phases.It is recommended that representative positions be selected for trial, that ground, vehicle or equipment data be recorded and that the scope, connection and frequency of maintenance be adjusted to the results;Changes in conditions have confirmed that early experience will not be directly applied to the entire emergency relief and post-disaster temporary access project.

Ambulances, fire trucks, material trucks and engineering machinery may arrive at the same time, and if no movement is made, narrow passageways may be blocked and heavy vehicles may also be damaged by the routes set for light vehicles.An emergency does not amount to disorder.Command personnel shall identify single-direction lines, meeting points, turning areas and priority vehicles, and set up access points and wireless communications.The sheeting teams synchronized with traffic movements to ensure that vehicles were not looted until the route was completed.The use of reflective boundaries and lighting at night and the prohibition of parking on passages to unload cargo;Re-check the most heavy vehicles and frequency of traffic as the relief phase changes.Emergency relief and post-disaster temporary access sites should set clear standards for decommissioning, such as continued tipping, incomplete support, extended depositions, visible vehicle slippages or loose links, “in short time and with mixed vehicle types, directions and priorities”.Unusual isolation and unloading were detected, and then the floors were repaired or reconfigured, and temporary pads were prohibited in carrying conditions.The head of the mission may not resume operations until he or she has been qualified to do so, and records of disposal are maintained.

Roadbanks may continue to be washed back by floods, with the aftershocks altering cracks and slopes, and the rains following the fire may trigger mudslides.The passage of a single inspection does not mean that the channel can be used on a full day basis.The site should have observation points and frequency of review, recording water levels, cracks, landslides, sutures and depositions;Over the pre-set threshold, the alternative route is immediately suspended and activated.The position of the legs of the lifting and pumping equipment will also be reviewed in the light of changes in the ground and cannot continue operations after the water has been emptyed under the plate.The evacuation routes and personnel assembly points remained clear and were not occupied by the stacks of materials.In response to “water levels, aftershocks and changes in the slopes that render established passages obsolete at any time”, the emergency relief and post-disaster temporary access project should also include the results of inspections in the pre-class confirmation and handover records, identifying who is responsible for release, who is responsible for inspection, what deposition or relocation must be discontinued.Retroactive recording of photographs, measurements and usages will make it possible to distinguish ground-based changes, operational deviations from product damage and avoid repetition of the same problem between different groups.
