Site safety should be your number one priority when setting up a construction site. If you are starting a new project and need some guidance on how to make your site safety compliant, we have rounded up a quick guide to create a safety compliant construction site in line with the Health and Safety Executive’s regulations.
Site rules should be clear and easy to understand for all personnel. If you have employees on site whose mother tongue is not English, you must provide the site rules in other languages to make them clear for these employees.
Every construction site employee must be given an appropriate site induction, including any tours of the site, training videos and practical training exercises applicable to your construction site.
For large sites that will have vehicles moving about them, it is absolutely vital that you have a traffic management system in place to ensure the safety of people on site.
This should include clearly demarcated routes for vehicles and for employees on foot. Warning systems for vehicles moving about on site and specific parking spaces for site vehicles.
You should also be providing first aid supplies, a registered first aider and other emergency equipment such as eye washes should an accident occur on site.
In addition, it is now important that you provide the proper personal protective equipment to mitigate the risks to your employees from airborne viruses. This could include masks, hand sanitizers and visors.
Undoubtedly, your construction site will generate waste and debris that will need to be managed properly. Domestic waste from site offices and staff areas should be separated for recycling and disposed of under the local council’s guidance.
Chemical and industrial waste should be handled efficiently too. It is important that you have a waste management contract in place with a reputable provider before you start work on site.
For many businesses, nitrogen gas is deeply integrated into the workday. Industries ranging from food processing to mining use this resource regularly, and the supply of it is essential to the core of operations. Unfortunately, traditional nitrogen gas acquisition requires the rental, delivery, installation, and removal of high-pressure cylinders. Canisters are inefficient, causing a lapse in production if delivery is late or supply is low. This process is not only more expensive than it needs to be, but it also creates more opportunities for workplace injuries.
Nitrogen generators, on the other hand, offer a better option. If your company is a regular user of nitrogen gas, consider installing your own nitrogen generator to enjoy the extensive benefits they provide.
What is a Nitrogen Generator?
Before exploring the many advantages of on-site nitrogen generation, it’s imperative to know what a nitrogen generator is and how it works. These machines perform processes called Pressure Swing Adsorption (PSA) and Membrane Technology, which extract nitrogen from the air and compress it.
Nitrogen generators offer a continuous flow of pure nitrogen right to your production floor and eliminate any need to wait for canister deliveries or remain at the mercy of supplier prices. While the resource provided is essentially the same, the generator produces the nitrogen rather than having it transported in cylinders.
Uses of a Nitrogen Generator
There are many applications for nitrogen gas across a variety of industries. Any industry that currently uses nitrogen canister, cylinder, dewar, or liquid deliveries can benefit from an in-house nitrogen generation system. Depending on what line of business you’re in, a nitrogen gas generator can work seamlessly into your manufacturing process in different ways.
One of the most common industries for nitrogen gas is food and beverage production. Nitrogen helps to preserve food inside its packaging and extend its shelf life. This is doubly important for bulk food products that might be stored for longer periods, as well as foods that don’t include preservatives in their ingredient lists.
The wine industry also benefits from nitrogen, as it helps keep the wine from going bad. In a non-consumable sense, nitrogen also extends the shelf life of things like paint and household solvents and prevents moisture and condensation in electronic part production. Additionally, nitrogen plays an integral role in quality assurance and consistency. On-site generators allow you to perform all of these tasks and more without a third-party supplier.
Why Make the Switch?
While disrupting and changing your current process can seem daunting, owning a nitrogen generator has numerous benefits that far outweigh any reservations you may have. The advantages of a nitrogen generator are widespread and touch on nearly every aspect of your business.
Replacing and transporting nitrogen cylinders presents a safety hazard to your team. Nitrogen generators stabilize the gas, so you don’t have to worry about explosions or injuries. In fact, they’re so safe that they can be installed right on the floor of your production room where they’re needed most. There is no risk to your employees’ wellbeing.
2. Unparalleled Reliability
Unlike canisters, cylinders, dewars, and liquid methods, nitrogen generators produce an infinite supply of gas, so you never have to worry about pausing production to wait for a delivery. While local nitrogen deliveries can run out or run late, a generator system keeps up with your demand and works on your schedule.
3. Fewer Wasted Resources
Approximately 10 to 20 percent of a canister’s, cylinder’s, dewar’s or liquid method’s nitrogen gas is left unused. This can lead to higher costs and waste production levels. Generators do not have this issue, so you can rest assured that all of your reserves are being used efficiently.
4. Increased Savings
While canisters, cylinders, dewars, and liquid methods come with expensive rental and delivery fees and restrictive contracts, generators require very little beyond their initial cost. In fact, most companies see a return on investment in under two years.
After the initial investment is recouped, generators cost about one-tenth of the price of canisters, cylinders, dewars, and liquid methods per year. That’s a 90 percent difference in operating costs, which creates a significant surplus for most companies.
5. Customization Options
Canister, cylinders, dewars, and liquid methods are one-size-fits-all, but generators can be tailored to meet your exact requirements. This means that your machine will work at maximum efficiency, producing the precise amount of gas you need to maintain operations.
Nitrogen generators can revolutionize your company’s production process, lowering your utility costs and improving your efficiency. Without dealing with the hassles of nitrogen cylinder delivery, you can grow your business to new heights.
The major contaminant in biogas is H2S which is both poisonous and corrosive, and causes significant damage to piping, equipment and instrumentation. The concentration of various components of biogas has an impact on its ultimate end use. While boilers can withstand concentrations of H2S up to 1000 ppm, and relatively low pressures, internal combustion engines operate best when H2S is maintained below 100 ppm.
The common methods for hydrogen sulphide removal from biogas are internal to the anaerobic digestion process – air/oxygen dosing to digester biogas and iron chloride dosing to digester slurry.
Biological desulphurization of biogas can be performed by using micro-organisms. Most of the sulphide oxidising micro-organisms belong to the family of Thiobacillus. For the microbiological oxidation of sulphide it is essential to add stoichiometric amounts of oxygen to the biogas. Depending on the concentration of hydrogen sulphide this corresponds to 2 to 6 % air in biogas.
The simplest method of desulphurization is the addition of oxygen or air directly into the digester or in a storage tank serving at the same time as gas holder. Thiobacilli are ubiquitous and thus systems do not require inoculation. They grow on the surface of the digestate, which offers the necessary micro-aerophilic surface and at the same time the necessary nutrients. They form yellow clusters of sulphur. Depending on the temperature, the reaction time, the amount and place of the air added the hydrogen sulphide concentration can be reduced by 95 % to less than 50 ppm.
Measures of safety have to be taken to avoid overdosing of air in case of pump failures. Biogas in air is explosive in the range of 6 to 12 %, depending on the methane content). In steel digesters without rust protection there is a small risk of corrosion at the gas/liquid interface.
Iron Chloride Dosing
Iron chloride can be fed directly to the digester slurry or to the feed substrate in a pre-storage tank. Iron chloride then reacts with produced hydrogen sulphide and form iron sulphide salt (particles). This method is extremely effective in reducing high hydrogen sulphide levels but less effective in attaining a low and stable level of hydrogen sulphide in the range of vehicle fuel demands.
In this respect the method with iron chloride dosing to digester slurry can only be regarded as a partial removal process in order to avoid corrosion in the rest of the upgrading process equipment. The method need to be complemented with a final removal down to about 10 ppm.
The investment cost for such a H2S removal process is limited since the only investment needed is a storage tank for iron chloride solution and a dosing pump. On the other hand the operational cost will be high due to the prime cost for iron chloride.
The mining sector is dedicated to the extraction of precious metals and mineral reserves from the earth. The extracted materials are transformed into a mineralized form that serves an economic benefit to both the mining company and the country. However, working in the mining industry has always been dangerous as fatal accidents in mines are a common occurrence worldwide.
While not all accidents and dangers can be prevented, there are some steps you should take to improve the safety for your workers. Failing to put in adequate safety measures could see you facing serious penalties. Here, we’ll look at 6 risks in the mining industry to be aware of and how to combat them.
1. Dust exposure
While dust may not sound like a particularly harmful risk, it can lead to serious respiratory problems. It is such a common occurrence in the mining industry that it’s been given the term “coal mine dust lung disease”. Some types of respiratory problems cannot be cured, so preventing them is key to your workers safety.
There are numerous dust prevention methods that can be used to combat the issue. Preventing dust from becoming airborne is key and it can be done through water. The type of machinery you use can also determine how much dust is released. Looking at ways to prevent dust build-up is key.
One of the more serious risks in the industry is the risk of an explosion. This is a particular worry for underground miners. The pipes within underground mines tend to contain flammable gases and chemicals. So, if the ventilation system isn’t maintained, it does pose a risk of an explosion.
Workers should continually check the ventilation system in mines and warning signs should be placed around the mine to remind them of safe practices.
3. Cave ins
There have been a number of cave-ins around the world that have caused devastation within the mining sector. In 2019, 21 miners died in China due to a roof collapse. It is a serious risk that can be difficult to fully prevent. Carrying out regular structural inspections is crucial to maintain the safety of your workers.
4. Electrical hazards
A number of electrical machines need to be used during the mining process. Unfortunately, this increases the risk of shock, fires and falls. If a worker were to get an electric shock, or trip over the equipment, you could end up having to make a large pay-out. You should always have adequate miners’ insurance from Arthur J. Gallagher.
All mines present some kind of fire risk. Even an excess level of dust in the mine can trigger a fire or explosion. The electrical equipment also poses a risk to workers. It’s a good idea to have a fire safety audit carried out before work is undertaken.
Finally, miners are also exposed to high levels of noise. They should be provided with ear protectors to prevent permanent damage. You’ll need to ensure you are providing high-quality protectors for adequate protection.
These are just 6 of the risk’s miners face. It is one of the most dangerous jobs in the world, but there are ways to minimise the risks. Making sure you are adequately insured is important. If your workers are to suffer an accident, they need to know they will be protected. Taking appropriate steps to improve the safety of the workplace is important for both you and your employees.
Household Hazardous Waste (HHW) are leftover household products that contain corrosive, toxic, ignitable, or reactive ingredients such as paints, cleaners, oils, batteries, pesticides etc. HHW contain potentially hazardous ingredients and require special care and safe disposal.
A typical home can contain a vast array of household hazardous wastes used for cleaning, painting, beautifying, lubricating and disinfecting the house, yard, workshop and garage. The chemical-based household products from a single home may seem insignificant; but, when millions of homes use similar products, handling, storing and disposing them improperly may have the combined impact and becomes a major problem.
The health and safety of our families, neighborhoods and environment is threatened when household hazardous waste is stored or disposed of improperly. These products should not be put in the garbage bins or disposed in the storm drains or burned, as they pose a threat to human health and the environment. Thousands of consumer products are hazardous. The general categories are:
Automotive products: Gasoline, motor oil, antifreeze, windshield wiper fluid, car wax and cleaners, lead-acid batteries, brake fluid, transmission fluid etc.
Home improvement products: Paint, varnish, stain, paint thinner, paint stripper, caulk, adhesives etc.
Pesticides: Insecticide and insect repellent, weed killer, rat and mouse poison, pet spray and dip, wood preservative etc.
Household cleaners: Furniture polish and wax, drain opener, oven cleaner, tub and tile cleaner, toilet bowl cleaner, spot remover, bleach, ammonia etc.
Other: Household batteries, cosmetics, pool chemicals, shoe polish, lighter fluid, prescription medicines etc.
Each year, thousands of people are injured by exposure or accident involving hazardous household products. Because of the dangers they pose. These products require special awareness, handling, and disposal. In order to protect health and environment, every consumer should know how to properly use, store, and dispose of hazardous household products.
Many common household products contain hazardous chemicals. Once released into the environment, these substances may pose a serious threat to living organisms. Small quantities of hazardous substances can accumulate over time to reach dangerous levels and contaminate the air, water, and soil.
Having your own private oil tank can be beneficial as you do not have to rely upon the main network which is typically less cost-effective and gives you less control over energy consumption. But having an oil tank installed also has its drawbacks. You have to be extra careful with it as not only its installation is complex but its maintenance requires a lot of hard work.
From ensuring that all the complex technicalities of installation are met to ensuring that the tank is in proper condition to function, now and then, you have to be careful at every single step.
And if you fail to do so or even lag slightly, you would expose yourself to the possibility of experiencing oil leakage or oil spills.
What happens if domestic oil spills?
If your tank starts spilling oil, the oil won’t just stay there but it will flow out to contaminate the adjacent areas. And if left untreated, it could go on to contaminate groundwater and soil.
This could lead to contamination of wells and water supplies of adjacent properties. Once the water supplies are contaminated, it could cause a myriad of drinking water problems. For example, oil damages the plastic water pipes so when it seeps into the underground water channel, it can affect the water pipelines that will ultimately lead to bad taste and foul odor in the drinking water.
Apart from this, oil spills can have a serious impact on human health as well. The first threat to human health spilled oil is through contaminated drinking water.
The second harmful impact they can have on our health is through disastrous fumes. As all petroleum products contain volatile compounds therefore when the oil is spilled it releases gases. If people nearby inhale these fumes or are surrounded by the vapors that linger in the air longer than usual, they can experience eye irritation, nausea, dizziness, headaches, drowsiness, and disorientation.
However, these symptoms are related to short term exposure to oil fumes. When a person is exposed for a very long time, which could happen if the smell of the fumes does not erupt shortly, then he could experience more serious conditions that would require a doctor’s consultation.
Skin irritation can also arise due to prolonged exposure or contact with the fumes. One could experience redness, severe irritation, and swelling.
How to handle oil spills at home?
Oil spills happen at both small and large scales. The larger ones require proper oil contamination treatment but the smaller ones can be dealt at home. But, this will require all of your attention and efforts. However, a domestic oil spill is not always easy to deal with, especially when the spill is massive and gets out of your hands.
Regardless of that, we should know a few tips and tricks to be well prepared to handle any such mishap because once an oil spill skyrockets, it causes severe damage to the surrounding and human health -as we discussed above.
The first thing that you must do when you have an oil tank placed in your residence, always check it regularly to look for any rusting or other damage to the tank. This way you can easily be one step ahead to deal with any leakage.
Somehow, if you fail to attend to any such damage and the leakage eventually occurs but it is small, place a pan where the tank is leaking to collect the spilling oil before it even touches the ground.
If this too gets out of hands and the oil starts spilling on the floor, try blocking that area to prevent the oil from spreading any further. You can do this by placing small dams as barriers and if that does not work then try using absorbents like cat litter, or sand.
If the flow of the oil dripping from the split of the tank gets a bit controlled then you can easily apply a sealant on the split. However, this is not a permanent solution as sealant only works temporarily. But this should give you enough time to contact professionals who deal with oil contamination treatment.
On the other hand, you have to protect yourself and your family in the midst of dealing with this chaos. This first thing you should do when your home smells of oil is to ensure maximum ventilation.
Open all the windows as well as doors so that the strong oil smell does not accumulate inside. This will also help in warding off the harmful petroleum fumes.
The next thing you have to do is to make sure that all of your family members, and especially children and pets are away from the spill location. If possible, have them evacuate the house for at least the time when the house is cleared of the smell and fumes.
While dealing with the spill, make sure that your skin and clothes do not come in contact with the oil. Remember to avoid smoking, drinking, and eating during and after you finish dealing with the oil spill. Also, try to examine the tank for the origin of the leak, and before doing that, make sure that the oil supply is turned off.
Who deals with the cleaning of oil contamination?
You can take care of the oil spill to some extent, but cleaning is entirely another process. All the things that have been contaminated with the oil, be it water, ground, or soil, only a team of specialists can do it properly.
Therefore, you should first call the professional before taking on the mission of curing the leakage flow, and when the team arrives, you leave the place immediately to ensure your health.
Dealing with domestic oil contamination might not be impossible but it is not recommended. The only thing you must do after calling the professionals is to ensure no one is around the site. Then let the expert team, who come with efficient methods of oil spill clean Up & bioremediation, take care of the rest.
In daily life, we make use of several different gases, liquids, and solids, without which life isn’t livable. And it’s not just oxygen that we use in daily life to keep the heart pumping, but there is an entire list of gases that are essential to keep on with life.
One of the most vital gases among all the other is carbon monoxide. This a potent and valuable gas that charges up heaps of electricity and starts up your cars. It’s essential to know what carbon monoxide is as it is widely used inside homes and can be just as dangerous as it is needed. It is a highly flammable gas that, if left unwatched, can create fire and unimaginable damage. For this reason, below are some ways to manage the carbon monoxide in your home to use it effectively and safely.
Carbon monoxide is a combustible gas and can be quite dangerous to have in a closed space, but it makes for many of the essential procedures used in a home. Your heating system most probably is run by carbon monoxide. And if it experiences a tear and a leak, the house could be in danger of destruction, and the residents could suffocate.
Check your heating and other fuel-burning appliances regularly to avoid any mishaps. It is best to get them maintained each year by professionals who can also check the systems for their effective running.
Mostly carbon monoxide can be detected by its firm odor similar to that of rotten eggs. This smell helps to give you a heads up to get out of your home and call for help. However, when there is a slight leakage that is undecidable, or the house residents aren’t awake to notice it, the situation can take a turn for the worst.
Some states have laws that require homes to have CO detectors installed. These detectors should be present on each floor, especially the basement and areas where there are fuel appliances and heaters. It is best to make sure the indicators are installed near bedrooms to get alerts while sleeping.
Check the Air Quality
In small houses or congested areas of a home, air can get trapped, and different gases can get clogged, the air quality unhealthy and dangerous to breathe in. Make sure that where you have your oven, furnaces, and fireplaces situated has a proper ventilation system installed. If there are vents already in place, check the air quality and clean them often.
Put Out Burners Effectively
Cooking is a necessity in all homes, and even though many households have replaced gas burners to electric burners, there are still many that use the gas cooking method. The gas used for cooking and heating is carbon monoxide, which is sturdy and highly combustible.
To keep safe from sources like these, make sure not to switch on stoves unnecessarily. Keep your fireplaces and furnaces covered to stop the gas from spreading and lingering in the air. Regularly validate that these places are well kept and clean. Also, make sure that the systems work well.
