Drainage and trenching

罚款和修理地下公用设施的费用

• Provincial, state or federal regulators can levy hefty fines to both the person excavating and the company responsible, depending on the local regulations

•维修公用设施的成本通常高于你原来项目的价值, 不包括填海和清理费用

电力、天然气和水等服务中断

• Underground utilities carry essential and critical services for the community. Interruptions to these are more than just minor inconveniences; they can put people, businesses and livelihoods at risk

•一些公用设施仅埋在地表以下12英寸处, 所以即使是一把简单的铲子也会造成严重的破坏

Risk of serious injuries and death

• Since 2008, the Pipeline and Hazardous Materials Safety Administration (PHMSA) has reported 715 injured workers and 79 fatalities due to damages done to underground infrastructures during excavation work*.

我知道管道在哪里，我还需要打One-Call吗?
You can never be sure where underground utilities are unless they have been marked by a professional. Utilities can shift from erosion or natural forces or new ones may have been installed without your knowledge. 使用免费的一次通话服务，您可以安全地进行工作.

我如何联络本地的一次通话服务?
幸运的是，有一些资源可以帮助您轻松地获得本地服务. In Canada, you can visit www.ClickBeforeYouDig.com 查找本地的一站式服务, 以及你们省其他有用的安全挖掘规章制度. In the U.S. you can dial 811 or visit www.call811.com 联系你所在州的医疗机构.

When do I need to make a One-Call?
你需要在干扰地面的任何时候发出定位请求. This includes digging, piling material, paving or even driving equipment over a right-of-way. Any action that could impact something below the surface counts as ground disturbance.

What is a crossing agreement?
A crossing agreement is an agreement between you and the pipeline operator that allows you to conduct your work safely with the permission and understanding of the pipeline operator. 对工作的任何更改也需要得到批准，以确保您的安全.

我如何知道我是否需要交叉协议?
If you plan to do any work on a right-of-way or access the right-of-way while conducting your work, 很有可能你需要一个交叉协议. To find out for sure, you can either make a One-Call and wait for the pipeline operator to contact you, or you can contact the pipeline operator directly through their crossings team. 联系信息可在此页找到.

What is the “prescribed area”?
The prescribed area is the area that extends 30 metres on either side of the pipeline centerline. 此区域内的地面干扰需要书面同意.
