What is the third and fourth level of physical labor intensity stipulated by the State?

1. Level 3 Physical Labor Intensity

The average energy consumption value of an 8-hour workday is 7310.2 kilojoules per person, and the rate of labor time is 73%, i.e., the net labor time is 350 minutes, which is equivalent to heavy-intensity labor.

2. The fourth level of physical labor intensity

The average energy consumption value of an 8-hour working day is 11,304.4 kilojoules per person, and the rate of labor time is 77%, i.e., the net labor time is 370 minutes, which is equivalent to very heavy labor.

3. It is understood that the grading of physical labor intensity is a basic standard for the scientific management of labor protection work formulated in China, and is the basis for determining the size of physical labor intensity. The application of this standard, you can clarify the physical labor intensity of the workers of the key types of work or process, in order to focus and plan to reduce the physical labor intensity of the workers, improve labor productivity.

Related Details of Physical Labor Intensity

Physical Labor Intensity indicates the degree of intensity of physical labor, i.e., the degree of labor force consumption in the same time. The grading of physical labor intensity belongs to the fringe disciplines, which belongs to the scope of labor hygiene research as well as the important content of the research of ergonomics disciplines in the industrial engineering profession.

1, the labor intensity index is less than or equal to 15, physical labor intensity for the first level, equivalent to light labor.

2, the labor intensity index is greater than 15 less than 20, physical labor intensity for the second level, equivalent to medium intensity labor.

3, the labor intensity index is greater than 20 less than 25, physical labor intensity for the third level, equivalent to heavy labor.

4, the labor intensity index is greater than 25, physical labor intensity for the fourth level, equivalent to very heavy labor.
