In recent years, there have been frequent incidents of formaldehyde, whether at home or in rented houses, or in school dormitories, which have left the dangerous element of formaldehyde in a state of anxiety and fear。
In fact, in many cases, rather than wait for tragedy to come to regret it, we should be better prepared, especially for formaldehyde, the “hidden killer”。
So how do we judge whether the air quality is safe where we live now? It is believed that the best way to do this is to test the levels of formaldehyde in indoor air。
In general, the following are the most common methods of detection:
I. Announcements of the benefit
When animals become less active, are prone to disease, do not eat, and plants die and are yellow, it is very likely that the environmental indicators of new residences are inadequate。
Ii. Professional testing
By definition, it's a professional formaldehyde testing facility。
As required by our indoor air quality standards, formaldehyde is tested 12 hours after the closure of doors and windows and does not exceed 0. 1 mg/m3, a standard indicator used to guide healthy living conditions and is an internationally accepted standard。
Iii. Arbitrary course
While this approach is simple, the accuracy rate is not guaranteed and only a general test can be performed. It is usually available at the supermarket at home or online, with prices ranging from a dozen to dozens。
Iv. Human response
In general, when humans are exposed to formaldehyde over a long period of time, there are cases of larynx disorders, headaches, short chest and low breathing. In particular, when getting up in the morning, if these symptoms are particularly evident, it is important to be alert to the excesses of formaldehyde。
In addition, attention should be paid to the apparently stimulating smell of newly renovated houses in order to prevent formaldehyde from being exceeded。
How does indoor formaldehyde contamination work
I. Starting at source
Environmental materials should be used as much as possible to reduce sources of pollution, if funding conditions permit. Whether on board, paint or furniture。
If it is necessary to use plate furniture, it is also recommended to select the suitable furniture, select the products with a low formaldehyde content and seal it inside the plate。
Ii. Ventilation
Increased ventilation is definitely an effective method of formaldehyde。
A reduction in formaldehyde can be achieved by reducing the content of hazardous substances in indoor air through open window ventilation and indoor air flow. However, what is said here is that ventilation is not always open. Because it's also a skill to open a window。
Having read the above presentations, we believe that you have some knowledge of the small methods of formaldehyde testing, and we hope that this information will help you。
