1. organize the employees to enter the work area, get familiar with the work place, divide the work area, train and warn the safety accidents on site, and establish a five zone system for construction safety according to the company's requirements (the security guard is responsible for supervising the work safety of five employees).

1. make reasonable work schedule and time limit.
2. check the safety protection tools and testing equipment, check the working capacity of the vehicle, and check whether it can supply water and power.
3. open the septic tank 2-4 hours in advance, use axial flow fan for ventilation, and do a good job in protective fence and professional protection (to prevent pedestrians and vehicles falling into the tank and causing accidents).
iii. formal construction
1. check whether there is toxic gas in the septic tank with the instrument. in the absence of gas, the vehicle is organized to pump the floats into the septic tank.
2. the secondary treatment uses high-pressure washing car to dilute the deposited feces and sludge, release the hidden gas at the bottom of the septic tank, discharge the sewage into the septic tank, and then detect whether the septic tank contains toxic gas.
3. operators shall wear safety belts, fire ladders and long pipe respirators.
4. put the sediment into the septic tank, use the electric lifting equipment, and then put it into the sealed car for external transportation (this can ensure the sanitation problems of the construction site and external transportation links).
5. the operator must change the operation every 2 hours (cyclic operation).
cleaning standard: no floating surface, the pool wall is basically clean, and the site is basically sanitary.
understand the construction scheme of septic tank cleaning, what should be paid attention to when cleaning?

4. open the cover with a hook and open it in each fire water hole for about half an hour. this reduces the amount of methane in the septic tank.
5. then insert a bamboo pole about 5m long into the septic tank to get the depth of the sewage and sewage in the septic tank.
6. if the depth of the septic tank is more than 1.5 meters, we must put it in the septic tank with bamboo ladders or other ladders, which are 1 meter deeper than the septic tank.
