摘要总结AI 辅助解读
本法规规定美国境内运输含硫化氢（H2S）的酸性原油散装包装必须张贴毒性危害警告。核心要求包括：在可能暴露于H2S蒸气的每个位置（如人孔、装载头）设置最小边长100mm的菱形边框标记，或替代性地使用英文警告标签/标牌。旧版标记有过渡期豁免，但新运输需符合现行标准。该规定旨在防止吸入性中毒风险，直接影响危险品包装合规与现场操作安全。
A Bulk packaging used to transport petroleum crude oil containing hydrogen sulfide ( i.e., sour crude oil) in sufficient concentration that vapors evolved from the crude oil may present an inhalation hazard must include a marking, label, tag, or sign to warn of the toxic hazard as follows:
- (a) The marking must be durable, legible and of a size relative to the package as to be readily visible and similar to the illustration shown in this paragraph with the minimum dimension of each side of the marking at least 100 mm (3.9 inches) as measured from the outside of the lines forming the border. The width of the border forming the square-on-point marking must be at least 5 mm. The marking must be displayed at each location ( e.g. , manhole, loading head) where exposure to hydrogen sulfide vapors may occur.
- (1) Transitional exception —A marking in conformance with the requirements of this paragraph in effect on December 31, 2014, may continue to be used until December 31, 2016.
- (2) For domestic transportation, a packaging marked prior to January 1, 2017 and in conformance with the requirements of this paragraph in effect on December 31, 2014, may continue in service until the end of its useful life.
- (b) The border of the square-on-point must be black or red on a white or other suitable contrasting background. The symbol must be black and located in the center of the square-on-point and be clearly visible as follows:
ER19JA11.034
- (c) As an alternative to the marking required in (a) and (b) of this section, a label, tag, or sign may be displayed at each location ( e.g., manhole, loading head) where exposure to hydrogen sulfide vapors may occur. The label, tag, or sign must be durable, in English, and printed legibly and of a size relative to the package with a warning statement such as “Danger, Possible Hydrogen Sulfide Inhalation Hazard” to communicate the possible risk of exposure to harmful concentrations of hydrogen sulfide gas.
