Observe the microclimate indicators

Monitoring the working environment including microclimate monitoring in the working environment according to National Technical Regulation QCVN 26: 2016 / BYT on Microclimate – Permissible microclimate in the workplace The work allows micro-climate at work

Labor type	Air temperature range (oC)	Air humidity (%)	Air movement speed (m/s)	Thermal radiation intensity exposure area (W/m2)
Light intensity	20 to 40	40 to 80	0,1 ton 1,5	35 when exposed to more than 50% of the human body area 70 when exposed to more than 25% to 50% of the human body area 100 when exposed to less than 25% of the human body area
Medium intensity	18 to 32	40 to 80	0,2 to 1,5
Heavy intensity	16 ton 30	40 to 80	0,3 to 1,5

For environmental conditions, heat, high humidity, the speed of movement of air in the workplace can be up to 2 m / s. 

For working conditions in air-conditioned rooms, the air movement speed may be below 0.1 m / s for light labor, less than 0.2 m / s for average and less than 0.3 m / s for heavy labor if the ventilation in the room ensures the CO 2 concentration meets the permitted standard.

The difference in temperature according to the height of the working position does not exceed 3 ° C.
The difference in the horizontal temperature of the working area shall not exceed 4 ° C for light workers, not more than 5 ° C for medium workers and no more than 6 ° C for heavy workers. The temperature difference in the place of production and outdoors does not exceed 5 ° C.

I. DETERMINING METHODS

Methods for determining microclimate according to TCVN 5508 – 2009: Working zone air – Requirements on microclimate conditions and measurement methods.

II. MANAGEMENT REGULATIONS

1. Establishments with employees exposed to microclimatic factors must periodically organize measurement of microclimate testing at the workplace at least once a year and in accordance with the provisions of the Labor Code and the Safety Law. , labor sanitation.

2. Employers must provide adequate labor protection equipment for employees in accordance with the working environment in accordance with the law on occupational safety and sanitation.

3. If the microclimate in the workplace fails to reach the permitted value, the employer must immediately take measures to improve working conditions and protect workers’ health.

III. ORGANIZATION OF IMPLEMENTATION

1. This regulation replaces the Microclimate Standard in the Occupational Hygiene Standard issued under Decision No. 3733/2002 / QD-BYT of October 10, 2002 of the Minister of Health.

2. The Department of Health Environment Management – Ministry of Health shall lead and coordinate with relevant functional agencies to guide, implement and organize the implementation of this regulation.

3. Based on the practical requirements of management, the Department of Environmental Health Management is responsible for proposing the Ministry of Health to amend and supplement it accordingly..

4. In the case of national standards, international standards of microclimates cited in this regulation are amended, supplemented or replaced, the provisions of the new documents will apply.
