Construction Coordinator Practice Exam

What do the electrical grid mats that are bonded to a fluid-assisted boring system provide?

1. Increased speed of the boring process

2. Operator protection by equalizing electrical potential between operators and equipment

3. Additional stability to the boring machine

4. Improved visibility during the operation

The correct answer is: Operator protection by equalizing electrical potential between operators and equipment

The electrical grid mats that are bonded to a fluid-assisted boring system serve a crucial purpose by providing operator protection through the equalization of electrical potential between operators and the equipment. This is particularly important in construction and boring operations, where the equipment can create hazardous electrical environments due to the movement of electrical currents and the presence of fluids which can conduct electricity. By using these grid mats, any build-up of static or stray electrical charges can be mitigated, ensuring that there is no significant electrical potential difference that could lead to electric shock. This protective measure enhances safety for operators who are working close to the equipment and involved in the boring process. Therefore, the primary function of these mats is centered around safety and electrical grounding, emphasizing their critical role in maintaining a secure working environment.
