Use high quality 1.2mm steel plate. Design service life more than a decade and have a double layer fire-proof steel wall. Between two layers have 38mm insulation. According to OSHA standards, there are set up counters electrostatic grounding wire to connect. To prevent outflow of liquid accidents spray,there are 5cm leak-proof at the bottom.
The working procedure will be as below: Step 1: fill water in (there will be a marker on the water level gauge to indicate where will be the proper water level) Step 2: fill air in and the internal pressure stable at proper pressure- 3MPa (Test pressure will be 4.5MPa, to ensure the pressure won’t bigger that the proper level, we’ll pre-adjust the safety valve and it will activate to release the over pressure) Step 3: Move it to working area. Ready for using (push eye wash plate for eye/face washing, pull hand lever to turn on the shower) Step 4: When water capacity running low, release all air out and repeat Step 1, 2
