Issues regarding ventilation in hydrogen fluoride production facilities

2016-08-05View Original

Thread Content

I would like to ask the experts: For production facilities that use hydrogen fluoride, where the plant is a sealed structure, how should the frequency of ventilation in such a plant be determined? Is it necessary to consider emergency ventilation, and if so, how should the frequency of such ventilation be determined? Two options are being considered at present: one is to have regular ventilation in the factory building 6 times, with emergency ventilation occurring 12 times. Another option is to perform regular ventilation 6 times; in the event of an accident, local vacuum hoses can be used to draw air away from the leak site, thereby preventing the spread of the leaking gas. Or maybe some expert has a better solution. From the perspective of occupational health and safety!
