Indoor air quality analysis for public-acces building PAB

Analyzing indoor air quality is monitoring exposure levels of harmful gases like carbon dioxide (CO2), benzene (C6H6) or formaldehyde (CH2O) that could be present in buildings and spaces open to the public like offices, workshops, schools, etc. IAQ (interior air quality) monitoring is also relevant in private environments like our houses and apartments…

Indoor air quality analysis for public-acces building PAB

Indoor air quality analysis

Many chronic diseases – which cannot be transmitted – such as asthma or allergies are directly linked to a degradation of indoor air quality (iaq). Thus air quality analysis is becoming more and more mandatory for public access buildings (PABs) in order to preserve public health and safety. Several gases can be present indoors in working or living spaces. To correctly detect and monitor levels of exposure to different gases in PABs it is important to understand their presence. These gases are mainly emitted because of:

  • The presence of a chemical pollutant – like benzene or formaldehyde – exhausted while using building materials like paints or insulating foams.
  • The building’s age. Institutes for hygiene at work and studies of indoor air quality shed light on the negative effects on health induced by formerly used substances.
  • The new high-quality constructions standards related to insulation and tightness that are designed to recycle rather than renew indoor air.

PAB indoor air quality testing: Targeted gases

Carbon dioxide

Carbon dioxyde (CO2) is naturally present at low concentrations in the air; it is colorless, odorless and heavier than air. This gas directly effects human health with headache, tiredness… While people gather themselves in a poorly ventilated space like an office, a classroom or a small room in a public-access building, the level of carbon dioxide rate in the air will grow.

Benzene

Benzene is the most dangerous indoor air pollutant. Current standards tend to limit its diffusion in buildings open to the public. The International Agency for Research on Cancer (IARC) classifies benzene as a category 1 (R25) carcinogenic agent. When ingested or inhaled, this organic compound is harmful to the breathing tracts – especially for lungs (R65) – and the eyes (R36) as well.

Formaldehyde

Formaldehyde is highly toxic if inhaled. This irritant gas can cause burns (R34). For a long time the International Agency for Research on Cancer (IARC) has been classifying formaldehyde in group 3: non-classifiable for its carcinogenicity. However, after series of studies in 2005, formaldehyde was finally classified as a group 1: proven carcinogenic agent.

Perchloroethylene

Perchloroethylene is a very toxic organic vapor that can be present near dry cleaning installations. Classified as a 2A (R40) substance by the CIRC, it can also be irritating to the eyes and breathing tracts, and can cause headaches and dizziness.

Our solutions for indoor air quality monitoring

Indoor air quality analysis consists of measuring and monitoring exposure levels to some harmful gases like carbon dioxide (CO2), benzene, formaldehyde or perchloroethylene. The short- time exposure limits and time weighted average values (STEL and TWA) are set by health and labor official government agencies - like the EPA and OSHA indoor air quality guidelines - and constantly evolve according to new knowledge on these substances.

Dosimeter tubes

TWA measuring system (time-weighted average) – also known as dosimeter tube or passive tubes gas detection – measures the time-weighted average concentrations of a gas in ambient air.

  • Gas detector tubes Dosimetric tubes
  • The dosimeter tube is inserted in its holder and wore close to the breathing zone (e.g. a shirt collar) to get an accurate measure of inhaled concentrations. This allows the monitoring of hazardous exposure during a working day.
  • Thanks to this system, wokers can easily get daily exposure concentrations and evaluate working areas. These simple and direct measures require no specific analyzis instruments or complex operation procedures.
