Are there dangers of gas in telecommunications? 

The telecommunication industry contains includes cable providers, internet service providers, satellite providers and telephone providers and confined spaces. Even simple above ground termination boxes may contain gas hazards generated from the cable runs underground. Gases such as methane, carbon dioxide and hydrogen sulphide can run through cable trunking accumulating in termination boxes and manifesting as hazards when the termination box is opened.

The risk of danger occurs when a worker is sent to carry out tasks involving opening up of enclosed volumes that may not have been accessed for a period of time. All telecommunications companies have these in abundance.

What are the Dangers?

Those working in the telecommunications industry are at risk from a variety of gaseous dangers, many of which could cause harm to their health and safety. Though less obvious, these risks should be taken as seriously as falls from heights or electrocution, and they require a similar level of training. A worker must not climb to an elevated position without a harness, similarly they shouldn’t be accessing confined spaces without appropriate confined space training. Awareness of the dangers present and minimising the risks that could lead to adverse effects is a well-known safety principle. Training and proper PPE can help protect workers from these hazards.

Gas Hazards and Risks

As there are many confined spaces in the telecommunication industry workers are at risk from the presence of hazardous and toxic gases there. Hazardous gases can also be linked to seemingly simple above-ground termination boxes. Gases such as methane, carbon dioxide and hydrogen sulphide sometimes travel through the cable trunking, and therefore, when the termination box is opened, a build-up of these gases can be released.

Enclosed or partially enclosed spaces with high levels of methane in the air reduce the amount of oxygen available to breathe and therefore can cause mood changes, speech and vision problems, memory loss, nausea, sickness, facial flushing and headaches. In more severe cases and prolonged exposure, there may be changes in breathing and heart rate, balance problems, numbness, and unconsciousness. There is also a risk of fire as methane is highly flammable.

Carbon monoxide (CO) consumption also poses serious health issues to workers, with those ingesting the toxic substance facing flu-like symptoms, chest pain, confusion, fainting arrhythmias, seizures, or even worse health effects for high or long lasting exposures. Hydrogen sulphide (H2S) poisoning causes similar issues, as well as delirium, tremors, convulsions, and skin and eye irritation. Carbon dioxide is an asphyxiant gas that can displace oxygen and hance dizziness.

Our solution

Gas detection can be provided in both fixed and portable forms. Our portable gas detectors protect against a wide range of gas hazards, these include Tetra 3 and T4. Our fixed gas detectors are used where reliability, dependability and lack of false alarms are instrumental to efficient and effective gas detection, these include Xgard and Xgard Bright. Combined with a variety of our fixed detectors, our gas detection control panels offer a flexible range of solutions which are able to measure flammable, toxic and oxygen gases, report their presence and activate alarms or associated equipment, for the telecommunication industry our panels include Gasmaster.

Transportation and Key Gas Challenges 

The transportation sector is one of the largest industries in the world, spanning a variety of applications. The sector offers services concerned with the movement of people and cargo of all types, across air freight and logistics, airlines and airport services, road and rail, transportation infrastructure, trucking, highways, rail tracks, and marine ports and services. 

Gas hazards during transportation  

The transport of dangerous goods is regulated in order to prevent, accidents involving people or property, damage to the environment. There a numerous gas hazards including the transportation of hazardous material, air conditioning emissions, cabin combustion and hangar leaks.  

The transportation of hazardous materials poses a risk to those involved. There are nine classification areas specified by the United Nations (UN) including explosives, gases, flammable liquids and solids, oxidising substances, toxic substances, radioactive materials, corrosive substances and miscellaneous goods. With the risk of an accident occurring being more likely when transporting these materials. Although the biggest cause for concern within the industry being the transportation of non-flammable non-toxic gas is asphyxiation. As a slow leak in a storage container can drain all of the oxygen in the air and cause the individuals in the environment to suffocate. 

Leaks within aircraft hangars and fuel storage areas of highly explosive aviation fuel is an area that must be monitored to prevent fires, equipment damage, and at the worst fatalities. It is essential to choose a suitable gas detection solution that focuses on the aircraft rather than the aircraft hangar, avoids false alarms, and can monitor large areas. 

Not only is it the external environment that faces gas risks in transportation, those working in the sector also face similar challenges. Air conditioning emissions poses a gas hazard threat due to the burning of fossil fuels leading to a subsequent emission of carbon monoxide (CO). high levels of CO in a confined area such as a vehicle cabin, of more than the normal level (30ppm) or an oxygen level below normal (19%) can result in dizziness, feeling and being sick, tiredness and confusion, stomach pain, shortness of breath and difficulty breathing. Therefore, proper ventilation in these spaces with the assistance of a gas detector is paramount to ensuring the safe of those working in the transportation industry.  

Similarly, in the air sector cabin combustion and fuselage fires, in the central portion of an airplane, poses a real threat. Although flame retardant materials are applied, if a fire does start the cabin’s trim and fittings can still generate toxic gases and vapours that could be more dangerous than the fire itself. Inhalation of harmful gases caused by a fire in these environments tend to be the main direct cause of fatalities.  

Transportation Standards and Certifications 

Each mode of transport, (road, rail, air, sea and inland waterway) has its own regulations but they are generally harmonized with the United Nations Economic Commission for Europe (UNECE). The Hazardous Materials Transportation Act (HMTA), enacted in the USA in 1975, states that regardless of the type of transportation, any company whose goods fall into one of the nine categories specified as hazardous by the UN, must comply with the regulations or risk fines and penalties. 

Those working in the transport sector in the UK must comply with the requirements laid out in the UN Model Regulations which assigns each dangerous substance or article a specific class that correlates how dangerous it is. It does this via the packing group (PG) classification, according to PG I, PG II or PG III. 

From an European standpoint the International Carriage of Dangerous Goods by Road (ADR) governs the regulations on how to classify, pack, label and certify dangerous goods. It also comprises vehicle and tank requirements and other operational requirements. The Carriage of Dangerous Goods and Use of Transportable Pressure Equipment Regulations (2009) also is relevant in England, Wales and Scotland. 

Other relevant regulations include the International Carriage of Dangerous Goods by Inland Navigation (ADN), the International Maritime Dangerous Goods (IMDG) and The International Civil Aviation Organization’s (ICAO) Technical Instruction
