Embodiment Construction

[0024] The present invention will be further described below in conjunction with embodiment.

[0025] A method for assessing the dust concentration exposure of thermal power plant operators is as follows:

[0026] 1. Investigate the working system of post A with 4 shifts and 3 shifts. The number of days included in a cycle completed by 4 shifts (indicated by A, B, C, and D) is 4 days. See the table below:

[0027]

first day

the next day

third day

fourth day

morning shift

[0028] 2. Use the individual dust detector to detect the dust concentration of each class, measure continuously for 4 days, and detect a total of 12 results, as follows:

[0029]

[0030]

[0031] 3. Take the arithmetic mean of the 12 results detected in the above 1 cycle, C 岗位平均 =0.91mg / m 3 .

[0032] 4. Under the long-term average weekly wo...

Abstract

The invention discloses a method for estimating the dust exposure concentration for operating personnel of a thermal power enterprise. The method comprises the following steps: determining the number of days for continuous measurement according to the working time, a duty situation and a working schedule of a station; detecting the dust exposure concentration of each crew by a dust detector, and calculating a periodic dust exposure concentration average value of the station; comparing the periodic dust exposure concentration average value with an adjusted national standard to judge whether the dust exposure concentration for the operating personnel meets the stipulations of the national hygienic standard or not. According to the method, the problem that the conventional detection evaluation method cannot evaluate the dust exposure concentration for the type of operating personnel is solved, and the concentration level of dust exposure for a worker is really reflected to the maximum extent.

Description

technical field [0001] The invention relates to a method for evaluating dust concentration of operating personnel in thermal power generation enterprises. Background technique [0002] Dust is the main occupational hazard factor in thermal power generation enterprises, but there are not many studies on the method of evaluating the dust concentration exposure of operating personnel. [0003] The national standard stipulates that the limit of long-term exposure to dust concentration of workers is "time-weighted average allowable concentration (PC-TWA)", which is the average allowable exposure concentration of an 8-hour working day and a 40-hour working week with time as the weight . [0004] The working system of the operators of thermal power enterprises mainly includes four shifts on five shifts and three shifts on four shifts. The working system of operating personnel is completely different from the traditional working system of 5 days a week and 8 hours a day. The worki...
