Approval of an American National Standard requires verification by ANSI that the requirements for due process, consensus, and other criteria for approval have been met by the standards developer. Consensus is established when, in the judgment of the ANSI Board of Standards Review

6、, substantial agreement has been reached by directly and materially affected interests. Substantial agreement means much more than a simple majority, but not necessarily unanimity. Consensus requires that all views and objections be considered, and that a concerted effort be made toward their resolu

13、ommittee on Safety in Construction and Demolition Operations, A10. It is expected that the standards in the A10 series will find a major application in industry, serving as a guide to contractors, labor, and equipment manufacturers. For the convenience of users, a list of existing and proposed stand

14、ards in the A10 series for Safety Requirements in Construction and Demolition Operations follows. A10.1 Pre-Project/Pre-Task Safety the employ-ees exposure level or estimated exposure level; a description of any personal protective and res-piratory equipment used or to be used; and information from

15、pre-vious medical examinations of an employee that is not otherwise available to the examining physi-cian. 6. The employer shall receive a written opinion from the examining physician which will include: a. The results of the medical examinations. b. The physicians opinion as to whether the employee

16、 has any medical conditions that would place the employee at increase risk of material impairment of the employees health from asphalt fume exposure or hazardous substances. c. Any recommended limita-tions on the employee or upon the use of personal protective equipment such as clothing or respirato

17、rs. d. A statement that the physician has informed the employee of the results of the medical examination and any medical conditions that require further explanation or treatment. 7. The employer will provide a copy of the written opinion to the employee. 8. The employer will maintain an accurate re

18、cord of each employees medical examinations. The record will include the name, social security number, description of the employees duties, written opinion and any employee com-plaints related to exposure to asphalt fumes.
