5、rds Institute, Inc. 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

This standard is one of a series of safety standards that have been formulated by the Accredited Standards C

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. The employer shall retain the (medical examination) records for the length of

19、 employ-ment plus 30 years. 9. The employer shall make the medical records available for examination and copying by the employees or former employees. 10. During examinations, appli-cants or employees found to have medical conditions which would be directly or indirectly aggravated by exposure to as

20、phalt type fumes shall be counseled on the in-creased risk of impairment of their health by working with this sub-stance. 11. In the event of illness known or suspected to be due to asphalt fumes, a physical examination shall be conducted in accordance with this section before the affec-ted person r

21、eturns to work. 4.6.9 If exposure to other chemicals also occurs, as is the case when asphalt is mixed with a solvent, emulsified or used concurrently with other materials such as tar or pitch, provisions of any applicable standard for the other chemicals shall also be followed to establish the mixt

22、ures Threshold Limit Values. 4.6.10 If hazardous chemicals or fumes are present in the asphalt mixture, warning signs shall be posted. Precautions should AMERICAN NATIONAL STANDARD A10.17-2006 (R2011) 19 be taken to prevent exposure of personnel to any amounts of hazardous chemicals or fumes in exce

23、ss of the TLVs as either liquid or vapor. Appropriate corrective measures shall be taken to eliminate the hazard or provide personal protective equipment. 4.6.11 When mineral dusts are present above the Threshold Limit Value, the possible contributions of silica dust and asbestos microfibers to caus

24、ing pulmonary disease shall be evaluated. Appropriate corrective action shall be taken to minimize the exposure of employees to such dusts (i.e. personal protective equipment). 4.6.12 All labels and warnings shall be printed in English. Illiterate workers and workers reading languages other than tho

25、se used on labels and posted signs shall receive information regarding hazardous areas and shall be informed of the instructions printed on the labels and signs. Labels shall be designed for the life cycle of the product. 4.6.13 Labels shall be affixed in a readily visible position on all tanks and

26、containers of hot liquid asphalt type materials containing the following information utilizing ANSI/SAE J 115, Safety Signs, for format and design: DANGER HOT ASPHALT MAY CAUSE SEVERE BURNS Do not get in eyes or on skin. Use only with adequate ventilation. Wear safety glasses, face shield, gloves an

27、d protective clothing when handling. First Aid. In case of asphalt type materials contact with eyes, immediately flush eyes with plenty of water for at least 15 minutes. In case of contact with skin, immerse affected part in cold water. If ice is available, pack ice on the asphalt adhering to the sk

28、in or apply an emergency cold pack. If difficulty in breathing occurs after inhalation, remove victim to fresh air and keep warm and quiet. If breathing stops, give artificial respiration. Call a physician as quickly as possible. AMERICAN NATIONAL STANDARD A10.17-2006 (R2011) 20 4.6.14 Labels shall

29、be affixed in a readily visible position on all tanks and containers of cold liquid asphalt utilizing ANSI/SAE J 115, Safety Signs, and ANSI/NEMA Z535.2, Environmental and Facility Safety Signs, or ANSI/NEMA Z535.4, Product Safety Signs and Labels, for format and design: DANGER (*ASPHALT) HARMFUL IF

30、 SWALLOWED MAY BE IRRITATING TO SKIN AND EYESDo not get in eyes or on skin. Do not take internally. Use only with adequate ventilation. Wear safety glasses, face shield, gloves and protective clothing when handled. First Aid. Obtain medical attention as quickly as possible. In case of contact with e

31、yes, flush eyes immediately with plenty of water for at least 15 minutes. In case of contact with skin, wash affected area with detergent and water. If swallowed, give milk or olive oil. DO NOT INDUCE VOMITING *Insert whatever is appropriate. 4.6.15 The following warning signs shall be posted in rea

32、dily visible locations on or near all equipment generating asphalt fumes: signs shall be posted in accordance with ANSI/SAE J 115. DANGER ASPHALT FUMES EXPOSURE AREA HIGH CONCENTRATIONS OF FUMES MAY CAUSE NOSE AND EYE IRRITATION FIRE HAZARD If respirators are required for protection from asphalt fum

33、es, the following statement shall be added in large letters to the required sign. RESPIRATORY PROTECTION IS REQUIRED IN THIS AREA In any area where it is likely that emergency situations will arise from accidental skin or eye contact or other excessive exposure to asphalt or asphalt type fumes, sign

34、s required by this section shall be supplemented by additional signs giving emergency and first aid instructions and procedures and the location of first aid supplies and emergency equipment, including respiratory protective equipment.

35、ring controls (primary), administrative controls (secondary), or personal protective equipment shall be used to maintain concentrations of asphalt type fumes below the recommended exposure limit (Threshold Limit Values). When a respirator is required by this section, it shall be selected from a list

36、 of respirators approved for use in accordance with the following requirements: 1. Respiratory protective pro-gram meeting the requirements of ANSI/AIHA Z88.2 shall be estab-lished and implemented. 2.

40、and their limi-tations. 9. Respirators will be regularly cleaned and disinfected after each shift. 10. Respirators will be stored in a convenient, clean and sanitary location. 11. Routinely used respirators will be inspected during cleaning and worn or deteriorated parts replaced. Respirators for em

41、ergen-cy use must be thoroughly in-spected at least once a month and after each use. 12. Respirators will be assigned to workers for their exclusive use. 13. Appropriate surveillance of work area conditions and the degree of employee exposure or stress will be maintained contin-uously during operati

42、ons requiring respiratory protection. 14. Regular inspections and evaluations will be conducted to determine the continued effect-iveness of the program. 15.
