FIGURE 4 POSITIONING OF GUARD

 

 Fig.1 shows the acceptable safe openings between the bottom edge of a guard and feed table at various distances from the danger line (joint of operation).

 The clearance line marks the distance required to prevent contact between guard and moving  parts.

 The minimum guarding line is the distance between the infeed side of the guard and the danger line which is 1/2 inch from the danger line.

 The various openings are such that for average size hands, an operator’s fingers will not reach the point of operation.

 After installation of point of operation guards, and before a job is released for operation, a check shall be made to verify that the guard will prevent the operator’s hands from reaching the point of  operation.

Rule 1980. (1) All new air receivers installed after July 28, 1995, the effective date of these rules shall be constructed in accordance with the 1980 edition of American Society Of Mechanical Engineers (ASME) “Boiler And Pressure Vessel Code,” Section VIII, “Unfired Pressure Vessels,” 1980 edition which is are adopted in these rules by reference in R 408.41902. and are available from the American Society of Mechanical Engineers, 22 Law Drive, Box 2350, Fairfield, New Jersey 07007-2350, or from the Safety Standards Division, Michigan Department of Consumer and Industry Services, Box 30643,  Lansing, Michigan 48909, at a cost as of the time of adoption of these rules of $460.00.

(2)  All safety valves used shall be constructed, installed, and maintained in accordance with the 1980  edition of the American society of mechanical engineers ASME “Boiler and Pressure Vessel Code,’ Section VIII, “Unfired Pressure Vessels,” 1980 edition which is are adopted in these rules by reference in R 408.41902.  and are available from the American Society of Mechanical Engineers, 22  Law Drive, Box 2350, Fairfield, New Jersey 07007-2350, or from the Safety Standard Division, Michigan Department of Consumer and Industry Services, Box 3064, Lansing, Michigan 48909, at a cost as of the time of adoption of these rules of $460.00.

(3)  Air receivers shall be installed so that all drains, handholes, and manholes are easily accessible. An air receiver shall not be buried underground or located in an inaccessible place.

 

 

(4)  A drain pipe and valve shall be installed at the lowest point of every air receiver to provide for the removal of accumulated oil and water. Adequate automatic traps may be installed in addition to drain valves. The drain valve on the air receiver shall be opened and the receiver completely drained frequently to prevent the accumulation of excessive amounts of liquid in the receiver.

(5)  Every air receiver shall be equipped with an indicating pressure gauge that is located so that it is readily visible and equipped with 1 or more spring-loaded safety valves. The total relieving capacity of the safety valves shall be adequate to prevent pressure in the receiver from exceeding the maximum allowable working pressure of the receiver by more than 10%.

(6)   A valve shall not be placed between the air receiver and its safety valve or valves.

(7)  Safety appliances, such as safety valves, indicating devices, and controlling devices, shall be constructed, located, and installed so that they cannot be readily rendered inoperative by any means, including the elements.

(8)  All safety valves shall be tested frequently at regular intervals to determine whether they are in good operating condition.
