Though the hottest days of midsummer have begun, countless outdoor workers are still dutifully fulfilling their responsibilities under the scorching sun, sweat raining down their brows. It is their hard work that keeps Ningbo up and running. They deserve to be celebrated and respected.
Water Purification
Plant Workers
The high temperature of sunny summer weather presents a daunting challenge for outdoor workers. At Ningbo Water Environment Group's Fuming Water Purification Plant, the equipment team leader Zhou Kefan is responsible for cleaning the grille plate.
He wore masks and gloves, holding a high-pressure jet hose. The air temperature had already climbed to 32℃, although it was not even 9AM; the ground temperature was well above 35℃. The growing heat accentuated the odor of sewage under the equipment.
Zhou switched the jet hose between his left and right hands to ease the soreness in his arms. The high-pressure water jet splashed against the grille, drenching him in dirty water. Zhou's transparent mask was soon covered with droplets of perspiration. His shirt was completely soaked.
After cleaning the grille plate, Zhou went to the blower room. "Two blowers will be maintained. Today, we need to fill the lubricating oil and clean the filter for these two devices."
The temperature in the blower room had reached 40℃. There was a strong smell of motor oil. Zhou and his colleagues picked up the vacuuming equipment, climbed up to the top of the 2.5-meter-high blower, and began cleaning the filter. After about half an hour, Zhou and his colleagues were sweating profusely, their clothes stained with grease. Completing one blower, they moved immediately to the second, without rest. To ensure the normal operation of the water purification plant, 262 pieces of equipment, both indoor and outdoor, need to be maintained regularly. Recently, over 150 new pieces joined the ranks of equipment that need regular maintenance.
Customs Officers
Air temperature 35℃, ground temperature 55℃, and ship deck temperature 61℃--such is the heat that Beilun customs officers experience almost every day recently. The resurgence of COVID-19 in other parts of the world means customs officers must conduct ship inspections frequently to prevent inbound cases.
At 1PM, an American container ship arrived at the Beilun No.2 Container Terminal of Ningbo Zhoushan Port. Zheng Leiming and Li Run from Beilun Customs were ready to board the vessel for quarantine inspection.
Zheng and Li quickly put on their masks, face shields, hazmat suit, and gloves and strode toward the docked ship.
The hot sun made the high, steep gangway hot to the touch. Holding their boarding kits in one hand and the railing in the other, the two officers made their precarious way up to the deck of the ship. By the time they reached the top of the gangway, their foreheads were already covered with fine beads of sweat. During busy times at the port, they would need to make almost a dozen such descents and ascents each day.
Once aboard, they began methodically checking the crew's temperature and health conditions. Checking crew's health card, reviewing the ship's medical logs, and conducting epidemiological surveys take at least one hour, during which the two officers must bear the sweltering heat in their hazmat suits.
Only after disinfection could they remove their protective gear, the inner layers of which would be soaked through. Zheng grabbed a bottle of water and drank it all in one gulp. The officers have to do these extremely hot inspections three or four times a day, and they are already used to it.
Bridge and Building
Inspectors
Chen Qiwei, a high rise maintenance worker from Ningbo Municipal Engineering Construction Group Co. Ltd, climbed a building's glass walls for repairs.
He needed to wear equipment weighing about 15 kg. In summer, after a morning of exposure, the temperature of glass building surfaces would rise to 40℃ or even higher, hot enough to burn the skin.
Working high above ground is highly stressful, given the inherent risks. "In one ascent, we can only do repairs along one vertical line. If the points needing maintenance are distributed on multiple vertical lines, workers need to make multiple ascents. Sunlight reflected by the glass sometimes interferes with the workers' vision, which could be a potential cause for accidents," said Chen.
Bridges across the city also need to be maintained consistently. Every year from June to September, bridge repairs are required more often than in other seasons. Workers focus on areas where there are expansion joints, such as sidewalks, and also on the overall appearance of the bridge.
The inspection of the internal structure of the steel box girder was called "hellishly difficult" by the staff. After being exposed to the sun all day, the temperature inside the closed bridge structure is extremely high.
Recently, Ningbo is conducting routine inspection and structural inspection on all bridges across the city, to be followed up by safety risk assessments.
