Lead(4+) bis(oxosilanediolate) - Safety
Open Data Verified Data
The iron drum is packed with polyethylene plastic bags. 50kg net weight per barrel. Storage in a ventilated dry warehouse. When loading and unloading should be light to prevent packaging damage. Toxicity and protection: lead and lead compounds harm almost all organs of the human body. Such as the nervous system, blood system, metabolism and endocrine system, digestive system, cardiovascular system, etc. The early symptoms of lead poisoning are the appearance of lead lines at the edge of the gums (there may be no lead lines when there is obvious poisoning), and the so-called "lead" skin is earth-colored. In case of lead poisoning, if colic occurs when subcutaneous injection of atropine and other drugs. Wash hot water bath, warm abdomen, enema, etc., as well as diathermy and other emergency treatment. The maximum allowable concentration of dust or vapor is 0.01 mg/m3. Masks can block 95% ~ 97% lead dust. When the vapor concentration is high, a filter type gas mask or a hose type gas mask can be used to force the supply of fresh oxygen. Eating is prohibited during working hours in the workplace. Rinse your mouth and brush your teeth before and after meals. You must take a shower after work. Technical procedure requirements shall be strictly observed during the operation of lead and lead-containing substances. Wet substances that are prone to dust.
