Operator Aids

The DuPont Sabine River Works had reported between 35,000 and 40,000 instrument installations and more than 5,000 safety interlocks and alarms in 1988. The interlocks and alarms are divided into two classifications the operator aid is used to alert the operator of a nonhazardous abnormal condition that might otherwise be undetected the safety interlock or alarm refers to any equipment whose proper functioning is essential to prevent or signal hazardous process conditions that may threaten personnel or equipment.

In summary, the definition of the asphaltenes, the resins, and the nonvolatile oil fraction that occur in heavy oil and bitumen is an operational aid. Such separations cannot be based on any chemical or structural features of the constituent molecules (II, 13, IS, 19). 

This method consists of two, conceptually different parts. In the first part, the azimuth of each machine axis is determined relative to its own reference line (established by a laser beam) via offset measurements. According to our classifications, this part is relative, contact, manual and static in nature. In the second part, the azimuth of the different reference lines is computed using the IMU attitude measurements (Fig. 7), relative to each other or in absolute sense (geodetic azimuth). This part is relative or absolute, non-contact, semi-automatic (operator aid ) and dynamic. The comparison clearly shows that the first part restricts the method for relative or absolute, contact, manual and static applications.

Operational aids are devices that assist the operator in the safe operation of the crane by providing information or automatically taking control of a crane function. These include, but are not limited to, the devices listed in 1926.1416 ( listed operational aids ). 

If any deficiency in paragraph (d)(1)(xiv) of this section (safety devices/operational aids) is identified, the action specified in 1926.1415 and 1926.1416 must be taken prior to using the equipment. 

The devices listed in this section ( operational aids ) are required on all tower cranes covered by this subpart, unless othenvise specified. 

Operations must not begin unless the operational aids are in proper working order, except where the employer meets the specified temporary alternative measures. More protective alternative measures specified by the tower crane manufacturer, if any, must be followed. See 1926.1417(j) for additional requirements. 

If an operational aid stops working properly during operations, the operator must safely stop operations until the temporary alternative measures are implemented or the device is again working properly. If a replacement part is no ionger available, the use of a substitute device that performs the same type of function is permitted and is not considered a modification under 1926.1434.
