CHAPTER 11: CHEMICAL SENSITIVITY;
VENTILATION
Chemical Sensitivity
After you rst purchase your new recreational vehicle and sometimes
after it has been closed up for an extended period of time you may
notice a strong odor and chemical sensitivity. This is not a defect in your
recreational vehicle. Like your home, there are many different products
used in the construction of recreational vehicles such as carpet, linoleum,
plywood, insulation, upholstery, etc. However, recreational vehicles are
much smaller than your home and therefore the exchange of air inside
a recreational vehicle is signicantly less than a home. These products,
when new or when exposed to elevated temperatures and/or humidity,
may “off-gas” different chemicals, including formaldehyde. This off-
gassing, in combination with the minimal air exchange, may cause you
to experience irritation of the eyes, nose, and throat and sometimes
headache, nausea, and a variety of asthma-like symptoms. Elderly
persons and young children, as well as anyone with a history of asthma,
allergies, or lung problems, may be more susceptible to the effects of off-
gassing.
Formaldehyde
Most of the attention regarding chemical off-gassing surrounds
formaldehyde. Formaldehyde is a naturally occurring substance. It is
also a key industrial chemical used in the manufacture of the numerous
consumer products which we referred to above and used in the
construction of recreational vehicles. Trace levels of formaldehyde are
also released from smoking, cooking, use of soaps and detergents such
as carpet shampoos, cosmetics, and many other household products.
Some people are very sensitive to formaldehyde while others may not
have any reaction to the same levels of formaldehyde. Amounts released
decrease over time.
Ventilation
To reduce or lessen exposure to chemicals from off-gassing it is of utmost
importance that you ventilate your recreational vehicle. Ventilation should
occur frequently after purchase and at times when the temperatures and
humidity are elevated. Remember off-gassing is accelerated by heat and
humidity. Open windows, exhaust vents, and doors. Operate ceiling and/
or other fans, roof air conditioners, and furnaces and use a fan to force
stale air out and bring fresh air in. Decreasing the ow of air by sealing
the recreational vehicle increases the formaldehyde level in the indoor air.
Please also follow the recommendations contained in Chapter 2 regarding
tips to avoid condensation problems. Many of the recommendations
conntained in Chapter 2 will assist in avoiding exposure to chemicals that
off-gas.
Do Not Smoke
Finally, we recommend that you do not smoke inside your recreational
vehicle. In addition to causing damage to your recreational vehicle,
tobacco smoke releases formaldehyde and other toxic chemicals.
Medical Advice
If you have any questions regarding the health effects of formaldehyde,
please consult your doctor or local health department.
