蓄粪池、酱菜腌积池、下水道以及“老塘”矿井等场所,多居于地面之下,通风不良,里面多有有机物质的腐败分解,倘时间久了,便可有硫化氢及二氧化碳气体的产生和积聚。若事前未进行充分的通风,又缺乏必要的个人防护,便贸然进入上述场所工作,就有发生急性硫化氢中毒的可能,“老塘”矿井则多见急性二氧化碳中毒。发生急性硫化氢及二氧化碳中毒时的现场急救,
Septic tanks, pickles pickles pool, sewer and “Laotang” mines and other places, and more living in the ground, poor ventilation, which decomposed more organic matter corruption, if over time, there may be hydrogen sulfide and carbon dioxide gas Production and accumulation. Without adequate ventilation in the past and the lack of necessary personal protection, it would be possible to cause acute poisoning of hydrogen sulfide poisoning when entering the workplaces mentioned above. The “Laotang” mine is more likely to see acute carbon dioxide poisoning. In the event of acute hydrogen sulfide and carbon dioxide poisoning on-site first aid,
