The Appropriate lighting for Hazardous Zones

The Appropriate lighting for Hazardous Zones

If you operate a potentially hazardous working environment, then it is up to you to ensure that workplace accidents are kept to an absolute minimum. Statistics on workplace accidents in South Africa suggest that while only 10% of all accidents are the result of unsafe working conditions, 88% of all incidents are the result of an employee’s actions, or lack thereof. This could be due to negligence or ill instruction, or it could be that hazardous zones were not clearly marked so that they could be easily avoided or navigated when need be.

A big part of ensuring workplace safety is to ensure that dangerous areas are clearly marked, and one of the most effective ways to do this is with lighting. However, when combustible materials are present in the area, the light fitting itself could pose a potential risk of ignition. For this reason, lighting plans should consider their environment carefully when having lighting installed.

More about Hazardous areas

As far as lighting is concerned, a hazardous zone is one in which a flammable substance is produced, handled or stored. In such areas, careful measures need to be taken to ensure that these substances are not accidently ignited. They can be divided up as follows:

                Zones 1 and 2

Zone 1 hazardous areas are those with the presence of high risk gases and vapours that create a potentially explosive environment. There is always a risk of a flammable mixture contaminating the atmosphere of the area, in which case a spark or heat source from any nearby lighting could act as a catalyst to disaster.

Zone 2 areas are those with areas with medium to low risk vapours and gasses present in a form where they are unlikely to (but still could) combust, such as in store rooms.

                Zones 21 and 22

Zone 21 materials are those that take the form of powder or dust, and present a relatively high risk of creating an explosive or flammable atmosphere even during normal operations. Processing areas where these materials are likely to be present, are extremely high-risk areas, and so require protected lighting that is safe to use without posing a risk of ignition.

Zone 22 materials are those that would not normally be in the position of creating an explosive environment, but could still do it under the right conditions.

Requirements for lighting in these areas

Protected light fittings that are suitable for high risk areas (particularly zones 1 and 21), should always be flame and explosion proof. That is to say that they should be sealed so as not to mix with gasses or fibres in the air. They should also be gas, dust or water resistant depending on their intended use, and they should be regularly inspected and maintained.

Benefits of LED Industrial Lighting

Benefits of LED Industrial Lighting

Selecting the correct type of industrial lighting for your operations will help you save money and energy, but will also ensure that all areas ore correctly lit so that accidents can be easily avoided at the workplace. There are a great many lighting solutions out there that are well-suited to industrial applications, but very few of them come with the extensive list of benefits offered by LED systems.

So, if you have been skirting on finally investing in LEDs and are just looking for that nudge forward, here are a few of the top advantages to using LED industrial lighting.

LED Lighting is extremely cost effective

When compared to fluorescent lighting, LED lights come at far less of an overall cost. While high quality LEDs will cost you more than fluorescents, they have a significantly longer lifespan which means you’ll spend less on replacements in the long run.

In addition to this, they operate economically, which means that you will be spending far less on accumulated power bills over time. Besides being a bonus to cost effectiveness, the economic performance of LED lights makes them environmentally friendlier than fluorescents, just another good reason to get them.

They require very little maintenance

As mentioned before, a high-quality set of LED lights will virtually never need maintenance, freeing up time to concentrate on the more crucial sectors of your production tasks while allocating areas of your maintenance budget to other areas.

LEDs work off of semiconductors that manage power input and output, which drastically reduces their energy consumption, thusly lengthening their lifespan.

Optimal operational temperatures

These semiconductors (otherwise known as drivers) are also able to regulate lighting and operating temperatures. In addition to managing power consumption, this also protects the LED from damage due to high temperatures. This feature also makes them able to withstand harsh environments where other lighting systems would need reinforcement.

LEDs reduce glair

Amongst the many features that semiconductors have allowed LED manufacturers to include in their products, the ability to manage glair levels has proved one of the most useful for industrial applications. Glair from harsh lighting can obscure vision which may lead to mistakes being made, or long-term optical injuries being sustained by your employees. Because of this, it is highly beneficial for any institution that conducts activities that require precision or long hours.

Features such as these also allow you to control the colour temperature in your working environment, which has a known effect on the moral, health and productivity of your employees, while reducing the risk of workplace accidents.

Contact Nordland Lighting for further details

There are a great many benefits to be taken advantage of for any institution that opts for LED lighting in their industrial applications as opposed to florescent systems. The benefits of overall cost and efficiency, durability and functionality are but a few.

Different Types of Lights

Different Types of LightsIn the 19th century, the very first incandescent lamp was invented by two gentleman, Thomas Edison and Joseph Swan. Since then, there has been many improvements in different types of bulbs and their efficiencies. There are several types of lights and they have all been designed with a considered image in mind. Main types of bulbs are commonly found in the lighting systems of offices, homes or factories. The performance of a light depends on the bulb, different light bulbs create different lighting effects.

A lamp is a device that creates light by an electrical current, and is a form of artificial lighting. Lights are important for a lighting system and present effective lighting. Usually, electrical lights are powered by centrally generated electrical power. If main lights bomb out, lights can also be powered by batteries, cell phones or generators.


These are standard bulbs that many people are familiar with. Incandescent bulbs are offered in a wide range of voltages and sizes. This light bulb glows and creates heat when electricity travels through the tungsten filament inside the bulb. Incandescent light bulbs generate a steady heat, which is suitable for household applications. The luminous efficiency of these light bulbs is around 15 lumens per watt.

Compact Fluorescent

A compact fluorescent bulb is a modern kind of light bulb that operates like a fluorescent. This light contains mercury, which leads to difficulties when disposing. Most compact fluorescents consist of around two or three tubular loops, and sometimes look similar to incandescent bulbs. These bulbs cannot be used with dimmers, and can last for around 10 000 hours. The luminous efficiency of this kind of bulb is around 60 lumens per watt.


The halogen bulb consists of tungsten filament, which is closed with a transparent envelop and filled with inert gas and small amounts of halogen. Halogen lamps are smaller than most. The luminous efficiency of the halogen is 25 lumens per watt.

Metal Halide

Metal halide bulbs include a discharge tube or arc tube in the bulb. These tubes can be created from either quartz or ceramic and contains mercury. Metal halide lamps create an impressive amount of light for their size, and are one of the most effective. These lamps are commonly found in halls, stages and traffic lights.

More on Different Types of Lights

Light Emitting Diode

LED lights are an electrical component that emits light through electrons in a semiconductor device. It does not have as much filament, using less power and has a long lifespan. LED lights produce a greater amount of light than incandescent lights and help preserve energy. These diodes are able to emit light of an intended colour without needing colour filters.


A fluorescent bulb is a gas discharge tube that utilises fluorescence to create visible light. Luminous efficiency of the fluorescent tube is around 45 to 100 lumens per watt. Compared to incandescent lights, these lights use less power for the exact amount of light. Fluorescent bulbs do not have a good colour ability, but are cool in appearance and colour.


A neon light is a gas-discharged light that contains gas at low pressures. It is constructed by mounting two electrodes in a small glass envelop. Standard brightness bulbs are filled with a neon or argon gas mixture, as well as high-brightness lights filled with pure neon gas. When a voltage is applied, gas ionizes and starts glowing, allowing a small current to travel through.

High Intensity Discharge Lamps

Metal halide, self-ballasted-mercury lamps, mercury vapor and high-pressure sodium lamps are all high intensity discharge lamps. These kinds of lamps are specifically designed with inner glass tubers that have tungsten electrodes with electrical arc. These lights create a large amount of light compares to traditional lights. High intensity discharge lights are commonly used when high amounts of light are required over large areas, this may include pathways, gyms, roadways and parking lots.\

Low Pressure Sodium Lamp

This light is the first sodium lamp that has the maximum efficiency than other lighting systems. These lights operate similar to fluorescents and have a brief heating up period before the light reaches full brightness. Low pressure sodium lamps are usually used in roads and parking lots where colour is not needed.

Fluorescent lights are a large part of the lighting family. The standard fluorescent light was developed in the 1930’s for commercial use. There are three key types of fluorescents; cold cathode, hot cathode and electroluminescent.

Advantages of Fluorescent Lights:

  • Energy efficient.
  • Affordable production costs – fluorescent lights are 66% cheaper than traditional lighting and provides the exact amount of brightness.
  • Long life of tubes – The average bulb or tube has the lifespan of six times longer than a traditional light. Fluorescent lights tend to burn less after being used continuously.
  • Variety of colours.
  • Diffused light.

What are the differences between a fluorescent light and an LED? Here’s what:

  • The main difference between a fluorescent and an LED is their energy usage and lifespan. Fluorescent lights last around 10, 000 hours before it is required to be replaced. LED lights, on the other hand, lasts up to 60, 000 hours. This means that one would have to replace a fluorescent light about 6 times to equal the lifespan of an LED.
  • LED lights are light emitting diodes, which may be found either as a single diode such as a flash light or as a cluster of diodes such as a light bulb. Fluorescent lights come in two primary types: CFL (compact fluorescent lighting) and tube lighting. These lights can range in sizes.
  • When it comes to energy efficiency, LED lights are around 5 times more efficient than fluorescent lights. This is because LED’s use around half the wattage of fluorescents.
  • LED lights are directional lights, which means that they focus on a specific area where the bulb is pointed. Fluorescent lights are ideal for illuminating rooms, with full sized tubes that can be used for large rooms such as warehousing, where LED lights will not be reliable.
  • LED and fluorescent lights are both energy efficient when compared to traditional lights. LED lights cost more than fluorescents, but, fluorescent lights contain small amounts of mercury.
