Sewage wells, cellars, basements, septic tanks, etc
These are common places in life
It's all limited space
They are closed or partially closed
Poor ventilation
It is easy to cause the accumulation of toxic, harmful, flammable and explosive substances
or insufficient oxygen levels
Accidents such as poisoning, suffocation, and explosion can be caused

The septic tank that is common in life is a limited space
Limited space is infinite danger
Children generally have a weak sense of safety
First of all
Be sure to educate your children
When encountering a manhole cover, go around and do not step on the manhole cover
In case of unfortunate danger
Be sure to learn the following rescue methods
Limited space is actually very common in production and life
Do you know what is a confined space?
What are the common risks and hidden dangers of limited space?
What are some common misconceptions
How to avoid accidents
Let's learn together
What is confined space
Limited space refers to the space that is enclosed or partially enclosed, with restricted entrances and exits but accessible to personnel, not designed as a fixed workplace, poorly ventilated, and prone to the accumulation of toxic, harmful, flammable and explosive substances or insufficient oxygen content. It is divided into three categories: underground limited space, aboveground limited space and confined equipment.
❶ Underground limited space, such as basements, underground warehouses, underground projects, underground pipe trenches, culverts, tunnels, culverts, pits, deep foundation pits, waste wells, cellars, inspection well rooms, biogas tanks, septic tanks, sewage treatment tanks, etc.
❷ Limited space on the ground, such as distiller's grains pond, fermentation pond, pickling pond, pulp pond, granary, silo, etc.
❸ Closed equipment, such as ship holds, storage tanks, vehicle-mounted tanks, reactors (kettles), kilns, furnaces, flues, pipelines and boilers, etc.
What is a confined space job
Common confined space operations include:
❶ Removal and cleaning operations, such as entering the sewage well for dredging, entering the fermentation tank for cleaning, etc.
❷ Installation, replacement, maintenance and other operations of equipment and facilities, such as entering the underground pipe trench to lay cables, entering the sewage regulating tank to replace equipment, etc.
❸ Painting, anti-corrosion, waterproofing, welding and other operations, such as anti-corrosion operations in storage tanks, welding operations in the cabin, etc.
❹ Inspection, maintenance and other operations, such as entering inspection wells, heat pipe trenches for inspection, etc.
Limited space risks and hidden dangers
Common types of accidents in confined space operations are: poisoning and suffocation, fire, explosion, drowning, fall from height, and electric shock.
Common misconceptions among people working in confined spaces
➤ "I" didn't smell or see any danger, so it's okay to enter.
➤ "I" just probe in to see, not really to go in.
➤ "I" take a look when I go in and come out quickly.
➤ "I" have checked it all, no problem, you don't need to test the instrument.
➤ Once something happens, pinch your nose and hold your breath to escape.
Accidents in confined spaces are frequent
Seems to be "mediocre in appearance"
But it's an invisible killer
How to ensure the safety of confined space operations?
Keep in mind the "three-word formula"!
