A Q&A On The Essentiality Of Gas Detectors In F&B

Important Answers Shared by NSB about Gas Detection

The first thing Nellai Saravana Bhava, the leading catering service in Tirunelveli, learned was the vital need for gas detection while preparing food. In the hopes that others are ready when they step into the industry, NSB answered some crucial questions related to gas detection.
  •    What is gas detection?
When food is prepared or collected, it produces gas either directly or as a by-product.  In big processors, gases are used to preserve food. Gas detection is monitoring these gases (produced or used) to ensure that hygiene standards are maintained and food quality is above par. Moreover, keeping an eye on the gases keeps those working around the area safe and secure.

Since some of these gases can be dangerous, monitoring is vital for safety management of not just employees but the entire operation. An example explains further on why gas detection in the F&B sector is essential.

Let say a pizza dough has been kept to rise. As the dough puffs up, it produces CO2. As the yeast and sugar ferment in the mixture, they create the gas which we see as bubbles in the crust after it has been baked.  If left unattended, the level of carbon dioxide can reach fatal levels, especially when the dough is made at a considerable level. So much so that it removes all oxygen in the room and suffocates any worker in the area.

An alert system would inform an employee when the levels of the adverse gas reach a predefined level. This detection and monitoring, therefore, keep the safety of the workers guaranteed.

  •    What are the common hazardous gases in the F&B industry?
Hydrogen chloride, Hydrogen cyanide, Hydrogen sulphide, Nitrogen dioxide, Phosphine, Ammonia, Carbon monoxide and Carbon dioxide. Let’s say, for instance, the CO2 level is above 1000 ppm. The workers in the area will feel drowsy and slight headaches. If the gas is not detected, and it crosses the 5000-ppm threshold, it will hamper production because employees will suffer severe consequences. CO2 above this limit will incur brain damage and coma in all workers in the area.

To prevent the levels from even reaching a slightly hazardous point, gas detectors and monitoring systems are needed.
  •    What are the types of gas detectors?
Primarily, there are two gas detectors – stationary and portable.

  • Portable gas detectors are those that can be transported anywhere in a manufacturing or preparation area. These can be connected to overalls or clothing and are best suited for a confined location. Because of their mobility, they can detect and alert a person of the level of CO2 (or any other gas) in both risky and safe areas. The detectors work on toxic, harmful and flammable gases.
  • Stationary sensors are fastened to one place. They warn people by triggering an alarm in advance. Fixed gas detectors make personnel aware before an explosion or toxicity.

Overview Of The Types Of Smoke Detectors

You all would be aware of the fact that smoke detectors are mostly used for detecting fire.  There are various types of smoke detectors being used in various places. It is essential that you choose the right smoke detector based on certain factors like fuel, flame, type of smoke etc. Certain type of smoke detectors detects a specific type of smoke and fire on various conditions.
Different types of smoke detectors that are used.
zIonization Smoke Detector
This is the earliest type of smoke detector which is used from the past. This type of smoke detector operates based on the radioactive elements where the free flow of electrons under typical situations. When a gas leak occurs smoke enters the chamber, and the normal flow of electrons is affected, and this makes the alarm to ring.
Photo-electric Smoke Detector
This type of smoke detector contains a transmitter and a receiver. When there is no leak, the transmitter transmits light to the chamber which is absorbed by the black walls, and the…

Safety Top Priority For Gas Detection Services

Safety Benefits of the Gas Detector The industrial process consists of the use of dangerous substances and combustible gases. This makes it crucial to engage a gas detection agency to avert potential hazards to industrial plants. Improper detection can lead to health hazards and risk to operational productivity. Prominent industries like iron and steel, hospitality and jewellery industry have signed up for gas protection. For instance, I Love Diamonds, an online jewellery retailer is one of our long standing clients and we protect their jewellery making workshop from potential gas dangerous. Our staffs take special training from, a source for critical information on occupational hazards.
Gas detection is the mechanism that detects leakage of gases. It is a no brainer to guess the importance of this system. Industrial processes use several hazardous gases that if exposed to humans can cause widespread devastation in terms of loss of life and detriment to the enviro…

Things You Should Know About Gas Detection System

What you should know about Gas Detection Technology ? In different industries, the safety of workers depends on various factors. In some environments where a worker is bound to come in contact with different gases, a worker there needs to be aware of the surrounding. Not knowing what gas they are taking in might create hazardous health issues for them. The gas detection system can help a worker detect the gas present in the environment around them. By knowing the percentage value of the gases presents around a worker can take appropriate safety measures. Gas detectors can help much more than what you know by now.
When entering into a research space, you never know what you are coming across. There can be a risk of explosives also present in the air. Without anybody knowing that there is an explosive gas in the atmosphere there is an increased threat of an accident. It is the responsibility of the people conducting the experiment or process should be aware of their surroundings. Any fl…
