Contractor and Visitor Safety Policy and Expectations

Contractors are a critical aspect of our daily operations at Jacobs. That is why we hold all Contractors and Visitors to the same Environmental Health and Safety expectations as our own employees. From the moment a potential contractor is selected until the time they complete the job, they must follow the guidelines of our Contractor Safety Program as outlined here.

All prospective contractors must complete the Contractors Safety Disclosure to be recognized as an Approved Contractor. Once the document has been submitted to the EHS Department, coordination of the project can begin.

Noise Concerns

Jacobs Vehicle Systems® has received inquiries regarding engine brake use and noise. The posting of engine brake signs along the roads and highways has created much controversy with both residents and drivers alike. This information has been established to inform interested parties about engine exhaust noise and provide the data and information necessary to understand the issue. We hope you find the information useful, and we welcome any feedback.

Information on Engine Exhaust Noise

Questions and answers:

I've seen signs posted that read "No Jake Brakes.” What does this mean?

Jake Brake® is a registered trademark of Jacobs Vehicle Systems. The term "Jake Brake" is sometimes incorrectly used to refer to compression release type engine brakes in general. The term correctly refers to all of Jacobs Vehicle Systems’ retarding products. When an engine brake is used on a vehicle with a poorly muffled or un-muffled engine exhaust (using straight pipes for example), the sound can be offensive, which is what prompted the sign you saw. The sign you saw might have unfairly used our trademark, making it brand specific.

I'm bothered by the noise of big trucks using their Engine Brakes, what can I do?

The federal government has required all vehicles manufactured since 1978 to meet noise requirements when delivered to the customer, so trucks have been required to meet the requirements when they leave the dealership as new vehicles for quite some time. The real problem here is modified or defective exhaust systems. The use of the engine brake is not the problem. Citizens and truck drivers can both do their part to keep the noise down. Citizens, encourage your local police to stop noisy vehicles and check them for muffler integrity. Truckers, if you know someone who is operating a vehicle with an excessively loud exhaust system, encourage him or her to fix it.
