Inspection of Industrial Production Tanks with Safety Tips

Dairy, pharmaceutical, food, and beverage industries have to keep hygiene at a very high level to ensure maximum safety of consumers. From a knife to an entire production tank, they keep everything free of microorganisms and corrosion. Likewise, continuous maintenance is a mandatory operation to comply with the safety standards of food and consumers. Tanks, tank manhole covers, pipes, machines, and every tool needs inspection for it. A minor error can lead to a disaster, which can threaten the existence of the whole company. Have a brief look at the inspection against some threats that can take place inside a production tank.  

Peeling of Coatings 

When a tank needs maintenance, it shows signs in the form of coat peelings. Those peelings mix with the solution inside the tank, which can change the PH value of it. Moreover, it can affect the production quality since the chemical coat has side effects if it starts peeling off. You need to inspect that peeling to fully remove it. This peeling means you need to apply a new coat. Special chemicals are used for it, so the old coatings can come out of the surface easily. Then you can apply new coatings inside the production tank. 

Rusting

It is not possible to avoid rusting inside a metal tank for a long time. Either from the liquid filled in the tank or from the environment, it will get corrosion somehow. That can add rust particles to the liquid you are processing inside the metal tank. From entire tanks to tank manhole covers, rusting can spread really fast. You need to do a sharp inspection for the detection of rust particles. Similarly, sacrificial anode, anti-rust coatings, and some other methods are used for protection. This rusting can slowly damage the metal surface, which needs the preventive method to be dealt with.  

Pitting Corrosion

Caused by chloride, pitting corrosion can damage a metal tank worse than rusting. It forms pits on the surface, which slowly become hollow. Then the whole surface of the metal tank starts deteriorating. Special chemicals and coats are applied inside the tank to prevent pitting corrosion. Similarly, different methods are applicable for protection from pitting corrosion. Cathodic protection and chemical coatings are some prevention methods in the industry. If you miss it, pitting corrosion can cause greater damage, which can result in welding works or the purchase of a new tank.  

Chemical Corrosion with Perforations

Another problem your metal tank can face is chemical corrosion. Some chemicals are not safe for specific metals. This means those chemicals can cause damage to that specific metal. If you are processing something that includes sodium chloride, hydrochloric acid, and sulfuric acid, stainless steel can face corrosion earlier than you can expect. Then these chemicals can cause perforations like pitting corrosions. These perforation damages are slightly different from pitting holes, but they end up with a similar fate. 

Safety Tips for Maintenance of Production Tanks

When you are about to do periodic maintenance, there are a few things you need to be aware of. Though professional cleaners enter these tanks, still, they need precautions to remain safe. These safety tips will be beneficial for the workers as well as for consumers.

Evacuation of Harmful Gases

 Never let your workers enter a production tank immediately, or they will have serious health problems. A production tank has many trapped gases, which are harmful for a human to breathe. Chemicals, fungi, and bacteria can lead to life-threatening gases inside a closed tank. To ensure the tank is safe to start maintenance, you need to evacuate all the gases with the help of a pump or machine. Then you should use gas detectors to sense if there are no molecules of harmful gas left. 

Removal of Any Smoke Generating Machine

Never carry a smoke-generating machine inside a production tank when doing its maintenance. That machine will fill the tank with carbon molecules, and they will suppress the possibility of breathing inside the tank. Even if your workers are wearing masks, still, it will be a bad move to carry a machine that emits harmful gas. In addition, do not carry that machine near the entrance of the tank. Otherwise, the tank will suck the smoke from outside. 

Safety Gadgets and Backup

Safety gadgets like oxygen masks, torches, whistles, and protective suits are mandatory for your workers. Those who have to enter the production tank need full safety from every possibility of an accident. In this modern era, you can equip them with a mic system to communicate better. They can call for backup or help as soon as they detect something harmful. There must be an air circulation system inside the tank as far as they work inside it. It will keep them safe from suffocation and heat trapped inside the tank.
