When inspecting a pond, how deep should the container permit be opened?

RT, at what depth does internal construction of a pool require a container permit?
To be precise, it should be called "confined space operations". Confined spaces refer to various towers, cauldrons, tanks, tanks, furnaces, drums, pipes, containers as well as basements, manholes, pits (pools), sewers or other closed or semi-closed places in production units. Anyone operating in the above restricted spaces must implement work permit management, and a "Confined Space Safe Work Permit" should be obtained before operation.
If the depth exceeds one meter and there is no air circulation, a restricted space operation permit must be obtained.
AQ3028-2008 Safety Specifications for Operations in Confined Spaces of Chemical Production Units Confined spaces include various towers, kettles, tanks, tanks, furnaces, drums, pipes, containers, and basements, manholes, pits (pools), sewers or other closed or semi-closed places in chemical production units. There is no clear rule on the specific depth. We actually determine it based on whether a person can easily escape after an accident.
When overhauling the pool, it should be determined according to the specific conditions of the pool. If the pool is open and well ventilated, the depth should be at least 2 meters before a "Confined Space Operation Permit" should be issued. If the pool is not open and has only one manhole, the concentration should be above 1.6 meters before a restricted space operation permit should be obtained.
Confined space operations are so-called high-risk operations because the operating environment is complex and dangerous. Unlike hot work, which only has the dangers of fire, explosion and electric shock, confined space work has to consider various injuries such as electric shock, poisoning, suffocation, falling from heights, and injuries. In addition, due to the limited space, it is not easy to escape and rescue in case of danger. If the poster mentioned that there are no such dangers in pit operations, then there is no need to consider issuing a certificate. Issuing a certificate is not the purpose, the purpose is to implement safety measures and prevent dangers!
different* * , industries have different requirements for this. It depends on the nature of the industry.
Confined spaces require work permits. Refer to AQ3218-2008 Confined Space Operation Specifications for Hazardous Chemical Enterprises
Yes, this kind of problem is difficult to regulate. We often encounter such problems at work. I really don’t know how to grasp the scale.
If there is no specific depth, then you will need to apply for a work permit.
There is no clear definition of how deep it should be. I think that according to the definition of restricted space, a pool used in chemical industry should be considered a restricted space. According to the safety management regulations for entering restricted spaces, work tickets must be processed strictly according to the above requirements, and no carelessness can be allowed! This is responsible for the enterprise and its employees.
What the poster is talking about is the restricted space operation certificate. AQ3028-2008 Safety Specifications for Confined Space Operations in Chemical Production Units has relevant explanations. There is no clear explanation to the depth. I think it mainly depends on whether there are dangers in the internal operations of the pool, such as: How big is the pool and whether it is easy for people to get in and out? ； 2. Is the oxygen content in the air in the pool qualified? ； 3. Whether there are toxic and harmful gases and whether there is a danger of combustion and explosion ； Wait, issuing a certificate is not the purpose. The purpose is to identify hazards before operation and implement safety measures to avoid accidents.
Sinopec regulations: Confined spaces refer to closed and semi-closed facilities and places such as furnaces, towers, kettles, tanks, warehouses, tankers, pipes, flues, tunnels, sewers, ditches, pits, wells, pools, and culverts in the production area. Before entering confined space operations, a "Sinopec Confined Space Operation Permit" should be obtained. The specific depth is not clearly defined. My personal opinion is that in chemical companies, since there are many dangerous chemicals that are heavier than air and are easy to accumulate in the above-mentioned ditches and pools, for safety reasons, it is best to issue a restricted space operation permit, especially when the head must be lower than the pool edge, a restricted space operation permit must be issued.
The definition of confined space in AQ3028 is very broad, and everything involved requires strict management. As for how deep a confined space operation certificate is required, I personally think that it should be based on whether people enter the operation. If people enter the operation, they should apply for it. The main purpose of issuing relevant standards is to prevent personal injury accidents when working in confined spaces.
in accordance with? But many times, companies’ supplementary standards are based on bloody accidents. Does this count as a basis?
What is described on the 3rd floor is unfounded. Even a small pit no more than knee deep can suffocate the operator. If you don’t have enough level and wealth, you can upload our company’s limited space operating procedures and share them.
There are no specific in-depth regulations. This can be understood to mean that whether or not to issue a ticket for safe operations in a restricted space depends on the degree of risk (this involves conducting a risk analysis of the operation before the operation). If the risk is high, an operation ticket should be issued, and if the risk is high, a ticket should not be issued.
Our company stipulates that any open container with a depth of more than 2 meters must issue a container operation ticket, and any closed container must issue a container operation ticket as long as people enter. There is no legal basis. It is stipulated by our company based on the actual situation and is for reference only.
