| | | As urban explorers, we know of the dangers that come with the places we long to know more about. However, all of us have come across signs (besides the typical “No Trespassing”) where some of us might or might not know what the meaning behind it is besides “danger: keep out.” After coming across a red sign that read “Warning: Hazardous Materials” on an outing with my roommate, we decided to do more research on signs, what their shapes and colours represent as to have a better idea of what we’re getting ourselves into. Dangerous substances usually found in abandoned buildings: Lead:When the body is exposed to lead — by being inhaled, swallowed, or in a small number of cases, absorbed through the skin — it can act as a poison. Exposure to high lead levels in a short period of time is called acute toxicity. Exposure to small amounts of lead over a long period of time is called chronic toxicity. Lead is particularly dangerous because once it gets into a person's system, it is distributed throughout the body just like helpful minerals such as iron, calcium, and zinc. And lead can cause harm wherever it lands in the body. In the bloodstream, for example, it can damage red blood cells and limit their ability to carry oxygen to the organs and tissues that need it, thus causing anemia. Asbestos: Asbestos fibers associated with these health risks are too small to be seen with the naked eye. Breathing asbestos fibers can cause a buildup of scar-like tissue in the lungs called asbestosis and result in loss of lung function that often progresses to disability and death. Asbestos also causes cancer of the lung and other diseases such as mesothelioma of the pleura which is a fatal malignant tumor of the membrane lining the cavity of the lung or stomach. Epidemiologic evidence has increasingly shown that all asbestos fiber types, including the most commonly used form of asbestos, chrysotile, causes mesothelioma in humans. Mold: Mold can cause a range of health issues from mild allergic reactions to severe respiratory illness. Colours and their Meanings: Orange: Explosive Red: Flammable Gas and Liquid White: Poison Black/White: Corrosive Yellow: Oxidizer Green: Non-Flammable gas Yellow/White: Radioactive Hazardous Materials by Class Numbers (The class number is the number located on the bottom corner of the label or placard): Class 1: Explosive Class 2: Gasses (Compressed, liquefied or dissolved under pressure) Class 3: Flammable Liquids Class 4: Flammable Solids or Substances Class 5: Oxidizers Class 6: Poisonous or Infectious Substances Class 7: Radioactive Substances Class 8: Corrosives Class 9: Miscellaneous Dangerous Substances The 704 Diamond is divided into four quadrants. Each quadrant of the diamond has a special meaning and is colour-coded. The top quadrant is coded red for fire hazard, the right quadrant is coded yellow for reactivity, the left quadrant is coded blue for health hazards, and the bottom quadrant is white and contains information about special hazards of the particular chemical. Each colored quadrant is also numbered for the degree of hazard from zero to four-four being the greatest hazard. RED...FIRE HAZARD Materials that burn readily 3. Materials that can ignite at room temperature 2. materials that ignite if moderately heated 1. materials that ignite after considerable preheating 0. will not burn YELLOW...REACTIVITY 4. may detonate 3. shock and heat may detonate 2. violent chemical change 1. unstable if heated 0. stable BLUE...HEALTH INFORMATION 4. deadly 3. extreme hazard 2. hazardous 1. slightly hazardous 0. normal material SPECIAL INFORMATION W: water may cause reaction COR: corrosive OXY: oxidizer ACID: acid

| The Durango '95 purred away a real horrowshow - a nice, warm vibraty feeling all through your guttiwuts. And soon it was trees and dark, my brothers, with real country dark. |
