Making a report on working environment observation

Work Environment Measurement Reports

QCVN is a qualified unit to monitor the working environment according to Official Letter No. 345 / SYT-NYV dated 18/01/2019 of the HCM City Department of Health.

The process of implementing labor environment testing includes:

Step 1: The field observation team of QCVN conducts monitoring of gas, toxic gas, physical factors, physiological and physiological factors, working positions … in areas where workers work.

Step 2: The expert team handles the records, synthesizes the information of the enterprise, the operation process and the monitoring results into a monitoring report, provides solutions for unsatisfactory targets / elements at the places where there are employees working with the aim of limiting the agents affecting the health, physiological and occupational diseases of workers …

1. Legal documents:

• Decree 39/2016 / ND-CP detailing the implementation of a number of articles of the law on occupational safety and hygiene.
• Guidance on writing labor hygiene records according to Appendix I.
• Decree 44/2016 / ND-CP detailing a number of articles of the Law on occupational safety and hygiene for technical inspection of occupational safety, safety training, occupational health and monitoring labor environment
• Guidance on making report on the results of working environment monitoring according to form 04 Appendix III

2. Method of measurement and analysis

• Measure the microclimate indicators: temperature, humidity, wind speed, according to the regulations of QCVN 26: 2016 / BYT of the Ministry of Health.
• Measuring lighting according to regulations of QCVN 22: 2016 / BYT of the Ministry of Health.
• Noise measurement according to QCVN 24: 2016 / BYT of the Ministry of Health.
• Measure and analyze toxic gas and dust samples according to the “Technical and Occupational Health and Environment Regulations 2015 – Volume 1”.

3. Standards:

• QCVN 22: 2016 / BYT National technical regulation on Lighting – The level of lighting for workplaces.
• QCVN 24: 2016 / BYT National technical regulation on Noise – Noise permissible exposure level at the workplace.
• QCVN 26: 2016 / BYT National technical regulation on microclimate – Value for microclimate at work place.
• Criteria for toxic gases, dust: Occupational hygiene standards in Decision No. 3733/2002 / QD – BYT.
• QCVN 27: 2016 / BYT National technical regulation on vibration-value allowed in the workplace
• QCVN 25: 2016 / BYT Exposure levels allow industrial frequency electromagnetic fields at industrial places
• TCVN 5508: 2009: Standard of working air area – requirements on microclimate conditions and measurement methods

4. Basic indicators in labor environment testing:

Physical elements:

− Microclimate:

• It is mandatory to measure 3 factors of temperature, humidity, wind speed, and thermal radiation only measures when the heat source is large and sunny.
• If VKH conditions are consistent, then 5 samples should be measured (4 corners and between that space). If heterogeneous, measure each labor position. Each of the narrow narrow working spaces (rooms, compartments, cabins …) must measure VKH.
• Standard for working air area – requirements on microclimate conditions and measurement methods: TCVN 5508: 2009.

Table 1: Specifying the number of measurement points according to the production area

Production base area (m2)	Number of measuring points
Under 100	4
100 – 400	8
Over 400	Determining according to the distance between working positions not exceeding 10m
