Hydrofluoric acid Waste treatment:

With excess lime water and precipitation of landfill disposal or recycling, the supernatant diluted then into the wastewater system.

Operation Hydrofluoric acid Personal protective equipment:

Respiratory protection: wear self-absorption filter respirators (including anti-HF cans), full cover or air respirator. 

Hand protection: impermeable gloves, rubber acid gloves. 

Eye protection: chemical safety goggles, wide green hard hat with a full face mask.

Limited storage, storage location and the usual drug storage area separately; should alkali, active metal powder, glass.

Goods stored separately, avoid mixing reservoir.

The storage area should be separated from the work area. 


Must do a good job security, a small area of exposure or contact have great harm. 

When a hydrofluoric acid container is opened, it is determined that the working area is well ventilated and no spark or ignition source exists. 

To ensure that the container material does not react with hydrofluoric acid, the need to use plastic material or Teflon material;

The use of the process to be very careful operation, and to avoid the release of steam mixed with daily life, work environment;

Using as little as possible the amount of emergency preparedness equipment for the treatment of spilled hydrofluoric acid;

Post warning symbols to ensure that personnel are kept away from other test areas.
