=== Wood Smoke === From an EPA article on wood smoke, specifically in relation to home wood stoves and fireplaces: HEALTH EFFECTS OF BREATHING WOODSMOKE \\ Summary: Numerous scientific studies report potentially serious adverse health effects \\ from breathing smoke emitted by residential wood combustion. Smoke contains fine \\ particles, which can affect both the lungs and the heart. Residential wood smoke may be \\ a significant source of exposure to fine particle pollution. ... Reduce Smoke to Reduce Exposure \\ People who heat with wood should do so as cleanly as possible. As a result of \\ federal air quality regulations, wood stoves and fireplace inserts manufactured after 1992 \\ are significantly cleaner-burning than those built earlier. These newer appliances -- \\ properly installed, in good working order, well-maintained and used correctly -- help \\ reduce outdoor and indoor air pollution resulting from burning wood, and consequently, \\ help reduce risks to health. Homeowners can further reduce those risks by switching to \\ cleaner fuels, such as gas. If people are burning wood for recreational purposes, they \\ should consider the impacts on their health, their family’s health, and their neighbors’ \\ health. http://www.epa.gov/burnwise/pdfs/woodsmoke_health_effects_jan07.pdf === Acrylic === Product Name: ACRYLIC \\ Chemical Name: POLYMETHYYLMETHACRYLATE\\ Inhalation: Stock shapes are not respirable, avoid breathing dust, as fine particles can be \\ inhaled and retained in the lungs. Section 4: First Aid Measures \\ If exposed to fumes from overheating, move to fresh air. Consult a physician if symptoms \\ persist. Chronic effects: Not considered toxic.\\ Unusual fire, explosion hazards: Under fire conditions, material may decompose to \\ form flammable and or explosive mixtures in air. \\ Hazardous combustion products: When heated to decomposition acrylic emits acrid \\ smoke and irritating fumes. Irritating to eyes, respiratory system and skin. http://www.cityplastics.com.au/pdf/acrylic%20msds.pdf === Styrene === Section 2. Composition and Information on Ingredients \\ CAS Number Chemical Name \\ 9003-55-6 Polystyrene \\ 9003-53-8 Modified Polystyrene \\ Section 3 Hazard Identification \\ Emergency Overview \\ The Polystyrene sheet is not expected to be an inhalation hazard under normal processing \\ conditions. If the material is processed under prolonged exposure to flame or high \\ temperature, thermal burns to the skin may occur and toxic gasses produced may irritate \\ the respiratory system. Hazardous Decomposition Products \\ Hazardous decomposition Products are Carbon Monoxide, Carbon Dioxide and various \\ hydrocarbons. Chemicals that are released from exposure to extremely high temperatures \\ (600 deg. F or higher) include Styrene Moner, Benzene, and other hydrocarbons\\ Chronic Effects on Humans \\ Carcinogenic Effects - classified none by NTP, none by OSHA. http://www.tapplastics.com/uploads/pdf/MSDS%20High%20Impact%20Styrene.pdf
