As if Katrina families had not suffered enough, concentrations of the gaseous irritant and carcinogen in FEMA trailers was found to be much higher than average after many Katrina families complained of symptoms they suspected were being caused by their FEMA provided mobile homes. Handling Chemical Carcinogens in the Laboratory: Problems of Safety. 10]**PEER REVIEWED**PRECAUTIONS FOR "CARCINOGENS": Rooms in which obvious contamination has occurred, such as spillage, should be decontaminated by lab personnel engaged in expt. Sweeping, brushing & use of dry dusters or mops should be prohibited.
The acute respiratory effects, eye irritation, and headaches experienced by mobile home sheltered Katrina victims made FEMA trailer Formaldehyde a national news headliner which spurred renewed concerns about off-gasing from structural materials found in most homes as well as trailers throughout the United States. Grossly contaminated cleaning materials should not be re-used ...
Testing, source control, ventilation, and air cleaning should all play a part in an effective reduction strategy due to how wide-spread this airborne toxin tends to be inside our homes. Handling Chemical Carcinogens in the Laboratory: Problems of Safety. 13]**PEER REVIEWED**Protect containers against physical damage. Store where temperature range is 16 deg C to 35 deg C. Inject "universal" gelling agent to solidify encircled spill and increase effectiveness of booms. If dissolved, in region of 10 ppm or greater concentration, apply activated carbon at ten times the spilled amount. Lyon, France: International Agency for Research on Cancer, 1979., p.
So reducing Formaldehyde gas hazards is often not as simple as buying eco-friendly furnishings, replacing carpeting with hardwood flooring, or creating a cigarette smoke-free environment indoors. A general index of technical names has also been compiled. The latter may be stored at room temp without precipitation of solid formaldehyde polymers because it contains 5-10% of methyl alcohol. Materials of construction preferred for storage vessels are 304, 316, and 347-type stainless steels or lined carbon steels. Treatment and Disposal Methods for Waste Chemicals (IRPTC File). published have not been tested on all kinds of carcinogen-containing waste.
Air testing will at least tell you if the alternate strategies besides source control will be needed. Lyon, France: International Agency for Research on Cancer, 1979., p. Spill-absorbent bags should be available for emergencies. Engineering controls in hemodialysis units should include (a) isolating the main system from personnel & patients in case of inadvertent spills or (b) disconnecting the dialyzers before the sterilization process is completed. This index should always be consulted when attempting to locate the appropriate procedures to be used when shipping any substance or article. Boston, MA: National Fire Protection Association, 1986., p. The uninhibited type must be maintained at a temp of at least 32 deg C to prevent the separation of solid formaldehyde polymers.
Formaldehyde Exposure 101In high school Biology classes I remember having to dissect pickled worms, frogs, baby pigs, and even a mink.
Yes it was a gruesome scene, but not nearly so gruesome as the sour odor from all the Formaldehyde (a.k.a. The teacher usually stored our mutilated critters in non-air-tight bags under her desk in between our hack job sessions.
Sources of Formaldehyde Gas in homes, workplaces, and schools is a very common culprit for causing general indoor air pollution, Sick Building Syndrome, and even increased risk of cancer. Handling Chemical Carcinogens in the Laboratory: Problems of Safety. 15]**PEER REVIEWED**Environmental considerations: water spill: Use natural barriers or oil spill control booms to limit spill travel.
You can read about my experience with this toxic gas below. Lyon, France: International Agency for Research on Cancer, 1979., p. Indoor storage should be in areas having floors pitched toward a trapped drain or in curbed retention areas. Use surface active agent (eg detergent, soaps, alcohols), if approved by USEPA. But back then the dangers of exposure to Formaldehyde was not as well understood so we suffered onwards with few eyebrows raised. The same public schools were also loaded with Asbestos and Lead-based paints back then too. Formaldehyde Exposure 102During my college years this toxic gas once again contributed to Building-related illness at the state university I attended. But hopefully you've never had to dissect a baby piglet or live in a FEMA trailer... Procedures should ensure that maintenance workers are not exposed to carcinogens. Particular care should be taken to avoid contamination of drains or ventilation ducts. Hurricane Katrina FEMA trailers used for temporarily housing victims of Hurricane Katrina in 2005/2006 became a very public focus of attention for Formaldehyde-caused Sick Building Syndrome. Lyon, France: International Agency for Research on Cancer, 1979., p. In cleaning labs, procedures should be used which do not produce aerosols or dispersal of dust, ie, wet mop or vacuum cleaner equipped with high-efficiency particulate filter on exhaust, which are avail commercially, should be used. So if Formaldehyde Gas is off-gasing from wallboard, ceiling materials, flooring, insulation or other structural components it would probably not be feasible to, first of all identify all the sources, and second of all rip them all out. 1216]**PEER REVIEWED**Stability/Shelf Life: On standing, especially in the cold, may become cloudy, and on exposure to very low temperature ppt of trioxymethylene formed; in air it slowly oxidizes to formic acid /40% solution/. and the hazardous material is properly classed, described, packaged, marked, labeled, and in condition for shipment as required or authorized by ... 165]**PEER REVIEWED**The International Maritime Dangerous Goods Code lays down basic principles for transporting hazardous chemicals. V11 244 (1980)]**PEER REVIEWED**PRECAUTIONS FOR "CARCINOGENS": Storage site should be as close as practical to lab in which carcinogens are to be used, so that only small quantities required for ... Carcinogens should be kept in only one section of cupboard, an explosion-proof refrigerator or freezer (depending on chemicophysical properties ...) that bears appropriate label. should be kept, showing quantity of carcinogen & date it was acquired ... Alkaline hydrolysis may be dangerous because of exothermic reaction.
