Face shield. <br />Part B: Level of Protection Requirements <br />The types of hazards for which levels A, B, C, and D protection are appropriate are <br />described below: <br />Level A --Level A protection should be used when: <br />1. The hazardous substance has been identified and requires the highest level <br />of protection for skin, eyes, and the respiratory system based on either the <br />measured (or potential for) high concentration of atmospheric vapors, gases, <br />or particulates; or the site operations and work functions involve a high <br />potential for splash, immersion, or exposure to unexpected vapors, gases, <br />or particulates of materials that are harmful to skin or capable of being <br />absorbed through the skin. <br />2. Substances with a high degree of hazard to the skin are known or suspected <br />to be present, and skin contact is possible; or <br />3. Operations are being conducted in confined, poorly ventilated areas, and the <br />absence of conditions requiring Level A have not yet been determined. <br />II. Level B --Level B protection should be used when: <br />1. The type and atmospheric concentration of substances have been identified <br />and require a high level of respiratory protection, but less skin protection; <br />and/or <br />2. The atmosphere contains less than 19.5 percent oxygen; or <br />Draft HMMP <br />March, 2000 <br />
