5、ational Standards 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 St
6、andards Review, directly and materially affected interests have reached substantial agreement. 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

GENERAL SAFETY Before each shift or operation, all electrical components, pneumatics and hydraulics, ha
33、nd and power tools, walking and working surfaces, handrails, toeboards, vehicles, first aid, exhaust systems and all plant machinery shall be inspected for possible hazards and safety requirements as specified by the original equipment manu-facturers instructions. Consult the manufacturers manual be
34、fore operating, installing or performing any work. 4.1 Manuals, Instructions and Train-ing. All personnel shall be familiar with the original equipment manufacturers safety procedures, Occupational Safety and Health Administration (OSHA) safety procedures, Material Safety Data Sheets (MSDS) guidelin
35、es and operating information pro-vided by the manufacturer. All equipment shall be installed, operated, maintained or repaired in accordance with federal, state and local rules and regulations. Only competent, experienced and authorized personnel should perform maintenance or operational duties. 4.1
36、.1 Manuals describing setup, oper-ating instructions, maintenance schedules and safety precautions shall be readily available to operators and maintenance personnel. 4.1.2 Manufacturers instructions, proce-dures, maintenance schedules, pro-grammed instructional material, and safety precautions shall
37、 be followed at all times. 4.1.3 Operators and maintenance per-sonnel shall be trained and instructed in the AMERICAN NATIONAL STANDARD A10.27-1998 (R2017) 14 recognition, avoidance and prevention of unsafe conditions including the safety rules and regulations applicable to their work in accordance
38、with the manufacturers recom-mendations and programmed instructional materials. 4.1.4 Only those employees qualified by training or experience shall operate equip-ment and machinery. 4.1.5. A safety instruction program shall be conducted on a regular and continuous basis in accordance with the origi

All visitors, unless they are known to be familiar with hot mix asphalt facilities operation and equipment, should be accomp
40、anied by an employee familiar with the hazards and safety procedures. 4.2 Hazard Identification. Many potential hazards exist due to the nature of the equipment, process and vehicular traffic. Documented inspections must be con-ducted to identify hazards. Hazards that are identified must be eliminat
41、ed or controlled. All potential hazards that cannot be eliminated or controlled by design or guarding shall be clearly marked and identified by signs or tags posted as a warning to all employees and visitors. Signs and tags shall not be used as a substitute for elimination of the hazard or guarding.
42、 4.2.1 Safety color codes used for marking hazards shall be designed in accordance with ANSI/NEMA Z535.1, Safety Color Code. 4.2.2 Warning signs and tags shall not be used in place of proper design or engineered controls. Signs and tags shall be used to identify hazardous conditions and provide a me
43、ssage to employees with respect to the hazard. 4.2.3 Signal Words. 4.2.3.1 Danger, warning and caution are used to identify levels of hazard seriousness from most serious to least serious.

The purpose of hazard communication is to provide employees with the right to know about hazardous materials and potential hazards of those materials that employees may
47、 be exposed to during performance of their work and to ensure employees know how to protect themselves from exposure. Information related to poten-tially hazardous chemicals and materials must be communicated to employees. Programs that identify hazards, train employees, plan emergency response to m
48、edical or environmental events and AMERICAN NATIONAL STANDARD A10.27-1998 (R2017) 15 require personal protective equipment shall be implemented. 4.3.1 Awareness.
