So the off-gasing of Formaldehyde was both constant and very concentrated in the Biology classrooms for weeks at a time. There were many complaints of headache, dizziness, watery eyes, and respiratory difficulty.
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.
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 ...
Air cleaning using an efficient air purifier that has the proper gas filtering media (such as the one below) can remove fumes reintroduced from source materials. Handling Chemical Carcinogens in the Laboratory: Problems of Safety. 11]**PEER REVIEWED**The following engineering controls are recommended to minimize formaldehyde exposure: 1. Also, formaldehyde vapors should be prevented from entering the room from the drains serving the main system & the dialysis consoles. [IMDG; International Maritime Dangerous Goods Code; International Maritime Organization p.3347, 8176-1 (1998)]**PEER REVIEWED**Storage Conditions: PROTECT AGAINST PHYSICAL DAMAGE. INDOOR STORAGE SHOULD BE IN AREAS HAVING FLOORS PITCHED TOWARD TRAPPED DRAIN OR IN CURBED RETENTION AREAS.
And ventilation with clean outside air can help to dilute what gets reintroduced but not immediately captured by any air purifier. Local exhaust ventilation should be installed over work stations using formalin or specimens preserved in formalin. Small quantities of formaldehyde should be purchased in plastic containers for ease of handling & safety. The air should be regularly monitored for formaldehyde, & in-service education should be conducted periodically on the effects of formaldehyde. MINIMUM STORAGE TEMP TO PREVENT POLYMERIZATION RANGE FROM 83 DEG F FOR 37% FORMALDEHYDE CONTAINING 0.05% METHYL ALCOHOL TO 29 DEG F FOR FORMALDEHYDE CONTAINING 15% METHYL ALCOHOL.
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. Glues and additives in many other synthetic materials and engineered wood products like "Oriented Strand Board" (OSB board) or particle board is why Formaldehyde is so commonly found at elevated levels in millions of homes. 706]**PEER REVIEWED**Formaldehyde gas is stable in the absence of water. Filter housing that is designed so that used filters can be transferred into plastic bag without contaminating maintenance staff is avail commercially. The lid should be secured & the bottles properly labelled. Concentration of formaldehyde in the soln should be below 2% in order to avoid excess exothermic reaction heat. Those sources are very common and often difficult to totally replace. Environmental Contaminant Reference Databook Volume 1. [Health and Safety Executive Monograph: Formaldehyde #2 p.2 (1981)]**PEER REVIEWED**Shipment Methods and Regulations: No person may /transport,/ offer or accept a hazardous material for transportation in commerce unless that person is registered in conformance ... Montreal, Canada and Geneva, Switzerland: International Air Transport Association, Dangerous Goods Regulations, 2001., p. Filters should be placed in plastic bags immediately after removal ... Once filled, bottles should be placed in plastic bag, so that outer surface ... Formaldehyde is a powerful reducing agent and many oxidants can be used, but may react violently (must be diluted). 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. This page covers everything you may want to know about this indoor air pollutant. Should not be stored in confined spaces or near open flames. Use mechanical dredges or lifts to remove immobilized masses of pollutants and precipitates. Emergency Handling of Hazardous Materials in Surface Transportation. Handling Chemical Carcinogens in the Laboratory: Problems of Safety. 14]**PEER REVIEWED**PRECAUTIONS FOR "CARCINOGENS": ... Incineration may be only feasible method for disposal of contaminated laboratory waste from biological expt. aqueous & organic-solvent solutions, otherwise it is necessary ... The pungent smell of Formaldehyde preservative was thick throughout the Biology buildings and after a ventilation failure, it and other air pollutants was suspected to have made many students and professors ill with headaches, nausea, and respiratory difficulty. Lyon, France: International Agency for Research on Cancer, 1979., p. A prominently displayed notice should give the name of the Scientific Investigator or other person who can advise in an emergency & who can inform others (such as firemen) on the handling of carcinogenic substances.
