Q. What metric measurements will be most important to drivers in assuring compliance with the Hazardous Materials Regula- tions? A. Some measurements affect placarding requirements or define hazard classes such as those listed below showing the metric units and the U.S. equivalent: 1. 454 kilograms (1,001 pounds) - the weight below which placarding is not required for Table 2 hazardous materials 2. 60.5° C (141° F) - the flashpoint that marks the upper limit for flammable liquids under the regulations 3. 60.5° C (141° F) and 93° C (200° F) - the flashpoints, above and below which a liquid ts classified as a combustible liquid under the regulation 37.8° C (100° F) and 60.5° C (141° F) - the flashpoints, above and below which a flammable liquid, such as diesel fuel and fuel oil, may be reclassified as a combustible liquid for domestic transportation only 450 liters (119 gallons) - the volume above which a packag- ing is deemed to be a bulk packaging for liquids 400 ke (882 pounds) - the weight capacity above which a packaging is deemed to be a bulk packaging for solids 454 ke (1,001 pounds) - the weight capacity above which a packaging is deemed to be a bulk packaging for gases 4,000 kg (8,820 pounds) - the weight of one commodity in non- bulk packaging for which identification numbers are to be displayed on a transport vehicle Q. Other than flashpoint, how does temperature apply to the classification of HM? A. Temperature may result in a material transported in a bulk packaging being classed as an “elevated temperature material” when that material ts: 1. A liquid transported at a temperature at or above 100° C (212° F) 2. A. liquid with a flashpoint at or above 37.8° C (100° P) that is intentionally heated and transported at or above its flash- point 3. A solid transported at or above 240° C (464°F)
