Welcome to today’s 1:5:10:365 Tip for becoming a better steward for our home and planet environment.

1:5:10:221 EcoTip: Filtration soiling is a clue that air is flowing from areas that may present an indoor air quality problems. If you notice a dark strip forming along the line where carpet meets a wall – this is filtration soiling. As air passes through the wall, particles of dust and debris are filtered out by the carpet. Of course carpets were never designed to be air purifiers, but this is an important clue that can indicate there is an issue with air infiltration.

:154 4-PC Alternatives

Filed under: :154 4-PC alternatives — Tags: , , , , , , , — John Banta @ 12:16 am

Welcome to today’s 1:5:10:365 Tip for becoming a better steward for our home and planet environments.

1:5:10:154 EcoTip: The GreenGuard product certification program places limits on the amount of 4-Phenylcyclohexene (4-PC) that can be emitted by adhesives and sealant products. The carpet industry has a new improved carpet testing program called Green Tag Plus which puts carpets and adhesives through a 14 day, 13 point test which includes 4-PC.

The following are some suggestions from the book I co-authored with architect, Paula Baker-LaPorte and MD, Erica Elliott Prescriptions for a Healthy House

  • Of the synthetic carpets, 100 percent nylon is considered one of the safest.
  • Choose carpeting that has little or no odor. Even the slightest odor on a small sample will be magnified many times in a fully carpeted room and can result in a very prominent, unpleasant, and unhealthy smell.
  • Choose your carpeting as early as possible so it will have the most time to air out prior to installation. Buy carpeting from a supplier who will agree to warehouse it for you. This means that the carpet will be unrolled and aired out in the warehouse prior to shipping.
  • Avoid carpeting that contains antimicrobial agents such as fungicides and mildewcides.
  • Avoid carpeting containing permanent stain-resistance treatment.
  • Avoid carpeting or pads containing styrene-butadiene rubber.

:153 4-PC

Filed under: :153 4-PC — Tags: , , , , , — John Banta @ 12:14 am

Welcome to today’s 1:5:10:365 Tip for becoming a better steward for our home and planet.

1:5:10:153 EcoTip:  4-phenyl cyclohexene (4-PC) is a reaction by-product of styrene and butadiene. All of these chemicals can be obnoxious and toxic, but 4-PC is especially obnoxious and best avoided. It is frequently found in carpet backing and adhesives.

***********************************

 Additional Information:

According to an EPA carpet study:

In the carpet finishing process, a secondary backing fabric is bound to a primary backing to provide strength and support. Precoat and adhesive are applied and cured at about 200° C in a gas-fired oven. This process is run on a continuous line. Precoat and adhesive formulations differ only slightly. Components include styrene-butadiene latex, thickener, filler, and water. Major VOC constituents found in the precoat and adhesive are long-chain hydrocarbons. In addition, several compounds derived from the latex were observed: styrene and butadiene (unpolymerized), ethyl benzene (styrene precursor), cumene (styrene-butadiene polymer catalyst), and 4-ethyl cyclohexene (4-EC) and 4-phenyl cyclohexene (4-PC), which are Diels-Alder reaction products of styrene and butadiene. 

Tommorow I will offer suggestions from the book Prescriptions for a Healthy House for ways to identify carpet that has been tested for low emission levels of 4-PC and other chemicals.

:066 Carpet Protectors

Suggested Review – :065

1:5:10:066 Tip: Carpet Protectors may keep office chairs from causing damage as they roll across the flooring, but excess moisture from concrete slabs can become trapped under the plastic resulting in mold and deterioration.
