A few days ago, the China Labor Safety Net responded quickly to the fact that the facade operator of a construction site in the sea area did not wear a seat belt and even noticed the violation of the helmet that was omitted.
At this site, the ascending workers all wear safety helmets and wear safety helmets. Even the ground commander wears a safety helmet and no “probe†plate is seen on the work surface. There is only one safety rope behind it, which makes the climber seem unaccustomed to limited mobility. Looking back at other nearby construction sites, the common “two non-wearing†status of workers has disappeared a few days ago.
It is still several months before the construction work is completed. It is still necessary to wait and see if we can strictly follow the safety regulations, and not merely posing temporary concerns to the media. Once everything is done according to the rules, it may affect the effectiveness and efficiency, but in exchange for life and health efficiency and efficiency will no doubt put the cart before the horse.

Fluorescent Brightener
Optical brighteners, optical brightening agents (OBAs), fluorescent brightening agents (FBAs) or fluorescent whitening agents (FWAs) are chemical compounds that absorb light in the ultraviolet and violet region (usually 340-370 nm) of the electromagnetic spectrum, and re-emit light in the blue region (typically 420-470 nm) by fluorescence. Fluorescent emission is a short-lived period of light emission by a fluorophore, unlike phosphorescence, which is long-lived. These additives are often used to enhance the appearance of color of fabric and paper, causing a "whitening" effect; they make intrinsically yellow/orange materials look less so, by compensating the deficit in blue and purple light reflected by the material, with the blue and purple optical emission of the fluorophore.
