Do you work for a water company that has improper safety features for it's employees? If so, then it is up to you to do something about it make sure that your safety is being taken care of for the long run. Safety Relief Valves have recently been installed at the Hoover Dam where they are able to guarentee that all of the employees will be around a safe work envirnment and keep that way for the rest of their career. Safety Relief Valves are small sensors that are places in areas where humans and employees normally don't go. An example would be a large sewer or a washway where water would trap any lifeform and keep them from breathing for long periods of time. Although these areas shouldn't have employees in them, there are times where accidents happen and where individuals must go into them to fix the problems. The sensors will go off with the slightest movement, and make sure that the individuals are safe. With movement the water will not flow into the runoffs and injure or cause fatal results.
