CARRIER AS 1101284 - Caterpillar

Apply the Scenario Factors
When you have looked up the vibration levels in the table, you must apply the scenario factors to these vibration levels, when the factors are appropriate.You will use these adjusted values in order to determine the Total Vibration Exposure Points (PE total).The scenario factors are displayed in the three columns on the right side of the table. The factors are easy to apply.If the task is similar to "Example 1", apply the following list:
subtract the x axis scenario factor from the x axis vibration level reading.
subtract the y axis scenario factor from the y axis vibration level reading.
subtract the z axis scenario factor from the z axis vibration level reading.Do not apply the scenario factors, if the task is average. An average task is described in "Example 2".If the task is similar to "Example 3", apply the following list:
add the x axis scenario factor from the x axis vibration level reading.
add the y axis scenario factor from the y axis vibration level reading.
add the z axis scenario factor from the z axis vibration level reading.Three Axis
Use the adjusted values and the exposure duration for each axis. Look up values for PEx, PEy, and PEz on the table 1.If the adjusted vibration level reading does not appear in the left hand column in the table, you must use the next highest value in the column in order to determine the P exposure.For example if your adjusted vibration level reading is 0.67, you must use the next highest value of 0.7 in order to determine the P exposure.The Total Vibration Exposure Points is the highest value of the three values (PEx, PEy, and PEz). The points are found in table 2.The value for PE total will help you determine the vibration control actions.White Area
The PE total value is less than 100. If the PE total value is in the white area, no action is needed. If the PE total value is close to the light gray area, you must take reasonable action in order to reduce vibration exposure. Provide the worker with information about reducing the vibration and with training about reducing the vibration.Light Gray Area
The PE total value is between 100 and 529. If the PE total value is in the light gray area, you must take reasonable action in order to reduce vibration exposure. Provide health surveillance for exposed workers.Dark Gray Area
The PE total value is greater than 529. If the PE total value is in the dark gray area, take immediate action in order to lower the Exposure Limit Value. If the exposure remains above the Exposure Action Value, you must take the following actions:
Activate control measures.
Activate a program of health surveillance.The following three examples show PE total values for different machines and for different conditions.Example 1
Compact Wheel loader - light vibration exposure
good working conditions (smooth terrain)
experienced operator
typical operating conditions load and carry motion
4 hour durationFind the vibration level values for x, y, and z axes for the compact wheel loader in the table.
