Types Of Electricity Meters And How To Read Them

By Ruth Carol Atieno

Currently, majority of households if not all have an electricity meter in place to measure the electricity consumption rates. But have you ever asked yourself what type of a meter you have? Or when it is time for a replacement and you wonder what kind of a meter you should buy?

In this blog, I will be taking you through the different types of electricity meters currently available in the market.

Accumulation Meters

These meters, also known as flat rate meters, are a traditional version of electricity meters. They measure the total amount of electricity used by a household and so you are only billed for the amount of electricity you use regardless of the time of usage.

To get the readings from a flat rate meter, you check the amount of electricity your household used since the last reading you made before. The billing is then done by comparing the difference between the current reading to the previous reading.

Interval Meters

An interval meter on the other hand measures electricity usage at time intervals of 30 minutes. It collects the data with the help of a spinning disc and has a digital display.

This therefore means that with these meters you will have different electricity usage amounts at different times in a given day. This is clearly an advantage as you are able to know the times during which your electricity consumption is high and so you can work out a plan to reduce the consumption.

To get readings from an interval meter the reader has to attach an optical probe to the meter to downloads the 30 minute interval data into a handheld computer. The readings are then sent to your electricity supplier so they can calculate your bill.

Smart Meters

These are more advanced interval meters as they give a more detailed understanding of electrical consumption of a household. This information can be used when it comes to reducing energy consumption rate and in the end saving money.

Smart meters measure the electricity used by a household digitally and then sends this information yo the electricity supplier who then does the billing. This digital reporting is done on a daily basis as the meter is in a position to communicate to a central computing system.

Non-Contact Distance Measurement

By Martin Ochieng

Background

Two types of technologies draw their application from the need to enable non-contact measurements. These technologies are optical and ultrasonic and have been used by experts worldwide for measurements and instrumentation.

Experts carried out experiments in the early adoption of these technologies to ascertain the efficacy of these approaches in a variety of conditions. These included moisture content, and type of soil; moving speed of the sensor; ambient temperature and sunlight intensity among other parameters.

The experiments revealed several benefits these approaches had and their drawbacks as well. The research conducted by these experts formed the basis of current non-contact measurement approaches including laser distance meters.

The laser distance meter

This article will focus on the laser distance meter used by engineers in making distance measurements quickly and relatively accurately as an important tool for an energy auditor.

Laser distance meters use lasers to accurately determine the distance between two objects without contact. These devices are also significantly useful to other professions relating to construction such as carpenters, masons, and locksmiths. Their popularity among a variety of technical professionals stems for its ease of use and high level of accuracy.

Uses during Energy Audit

The laser distance meter is a pretty handy tool during an energy audit. This tool provides the Energy Auditor with a quick and accurate way to measure distances between two objects.

This ease of measurement allows an energy auditor the ability to not only get a quick measurement of utilities and machines such as walk-in ovens but also allows measurements in situations where measurements would otherwise be unsafe to make. For instance, an engineer can determine the depth of an empty underground tank, the inside dimensions of a hot walk-in oven, among other hazardous environments.

The Eenovators LTD team uses the Fluke 414D laser distance meter. The figure below demonstrates the Fluke 414D used by the technical team during energy audits.

Its key features include:

  • Rugged, professional-grade laser distance meter featuring advanced laser distance measurement technology.
  • Instantly measures up to 50 m (165 ft.) with one-button point-and-click operation.
  • Offers Pythagoras calculation to indirectly measure the height from two other measurements.
  • Quickly calculate area (square feet/meters) and volume.
  • Offers easy-to-use addition and subtraction function.

Apart from the basic functionality, the device allows the user to track maximum and minimum values to enable measurements from stable measurement points and can store up to five measurement results.

The table below demonstrates the device’s basic specifications.

Conclusion

The laser distance meter is a crucial tool during the energy audit process and has provided viable measurement approaches in varied situations. These situations range from identifying the dimensions of a walk-in oven to measuring the cooled space within a massive data centre. The benefits of this tool make it a must-have for energy auditors.

High-Visibility Safety Apparel

By Karen Thuranira

High-Visibility Safety Apparel (HVSA)

High-visibility safety apparel (HVSA) is clothing that workers wear to improve how well other people see them or to improve how visible they are. These kind of clothing is often worn to alert drivers, vehicle and machinery operators of a worker’s presence. And most especially in low light and dark conditions.

One may consider having a high-visibility headwear to increase their visibility in situations where part or all of their body could be obscured e.g. when working in leafy areas with many trees, traffic barriers, construction materials, etc.

Situation that require High-Visibility Safety Apparel

High-visibility clothing allow you to be seen by the drivers and or machinery operators sooner and more readily. This fact increases your safety at work. You must have HVSA if;

  • You are working when there is low light and poor visibility.
  • You are working around moving vehicles (cars, trucks or other machinery traveling under their own power – e.g., forklifts, backhoes, etc).

How to choose the High – Visibility Safety Apparel that will work best for you.

It is recommended that an initial hazard assessment be carried out on each job site to evaluate the site for known or potential hazards a worker may encounter while performing the job. This assessment will help to determine the risk to workers of being hit by moving vehicles and the environmental conditions under which work is performed.

When doing the hazard assessment where HVSA might be required, consider the following;

  • Type and nature of the work being carried out – including the tasks of both the HVSA wearer and any drivers.
  • If workers will be exposed to heat and/or flames. If so, flame-resistant HVSA would be required.
  • Work conditions, such as indoor or outdoor work, temperature, work rates, traffic flow, traffic volume, visibility, etc.
  • The workplace environment and the background workers must be seen in (e.g., is the visual area behind the workers simple, complex, urban, rural, highway, filled with equipment, cluttered).
  • How long the worker is exposed to various traffic hazards, including traffic speeds.
  • Lighting conditions and how the natural light might be affected by changing weather.
  • Factors that affect warning distances and times, such as the volume of traffic, the size of vehicles, their potential speeds and their ability to stop quickly, and surface conditions.
  • If there are any engineering and administrative hazard controls already in place (e.g., barriers that separate the workers from traffic).
  • Any distractions that could draw workers attention away from hazards.
  • The sightlines of vehicle operators, especially when vehicles are operated in reverse.
  • For certain jobs, there’s need to be “visually” identifiable from other workers in the area.

Once a hazard assessment is complete, appropriate controls can be selected. The first line of defense for workers’ safety would be to control the design of the workplace and reduce the exposure of workers to moving vehicles (e.g., through the use of physical barriers and other engineering and administrative controls). Using high-visibility apparel would be the last line of defense against accidents by providing more warning to vehicle operators that workers are on foot in the area.

What to look for when purchasing High-Visibility Safety Apparel.

Size, Coverage and Design

  • Large, bright garments are more visible than small ones. Coverage all around the body (360° full body coverage) provides better visibility in all viewing directions.
  • Stripes of colours that contrast with the background material to provide good visibility. Stripes on the arms and legs can provide visual clues about the motion of the person wearing the garment.
  • When background material is bright-coloured, it is intended to be highly visible.
  • Other requirements such as flame resistance, thermal performance, water resistance, durability, comfort, tear-away features, material breathability and flexibility that are applicable to the job.
  • Be sure to select the colour and stripe combination that provides the preferred contrast and visual indication of movement.

Fitting:

  • For safety and best performance, garments should be fitted to the person. Always consider the clothing that might be worn underneath the HVSA garments, and how the garment should be worn. The HVSA should sit correctly on your body with no loose or dangling components, and stay in place during your work.
  • The apparel should be comfortable to wear. Parts that come into direct contact with the worker should not be rough, have sharp edges, or projections that could cause excessive irritation or injuries.
  • The apparel should be lightweight.
  • Garments should be selected and worn such that no other clothing or equipment covers the high-visibility materials (e.g. gloves, equipment belts, and high-cut boots).

Brightness:

  • Daylight – Bright colours are more visible than dull colours under daylight conditions (e.g. fluorescent materials are suitable for daylight).
  • Low light conditions – such as at dawn and dusk, reflective materials are highly recommended. In dark working conditions, greater retroreflectivity is needed as it provides greater visibility these conditions. Retroreflective materials provide high-visibility conditions and are preferred over bright colours. Fluorescent materials are ineffective at night and less visible than white fabrics.

Colour:

  • High-Visibility Safety Apparel Standards worldwide, specifies both the colour of the background and the stripes/bands. Class 1 (e.g., harness style) must have a minimum of 0.14 metres squared of background material.
  • Background material should be one of;
  • fluorescent yellow-green
  • fluorescent orange-red
  • fluorescent red
  • bright yellow-green
  • bright orange-red.

Care and Maintenance:

  • Keep your high-visibility apparel clean and well-maintained. Contaminated or dirty retroreflective materials provide lower visibility.
  • Replace garments that show signs of wear and tear, dirty or contaminated as they will no longer be able to provide acceptable levels of visibility.
  • Purchasers of HVSA should get proof that the materials used and the design of the garment meet the required standards.

Different classes of High-Visibility Safety Apparel

The Standards of High-Visibility Safety Apparel sets out levels of retroreflective performance (i.e., the effectiveness of material in returning light to its source), the colours and luminosity of background materials, and how much of the body that should be covered by the high-visibility components. There are also special requirements for garments that to provide electrical flash and flame protection. These Classes differ in that they specify body coverage rather than minimum areas.

Below are three classes of garments based on body coverage. Each class covers the torso (waist to neck) and/or limbs according to the minimum body coverage areas required for each class.

  • Class 1 provides the lowest recognized coverage and good visibility.
  • Class 2 provides moderate body coverage and superior visibility.
  • Class 3 provides the greatest body coverage and visibility under poor light conditions and at great distance.

When to wear the different classes of High-Visibility Safety Apparel.

After a hazard assessment is carried out, a person is able to tell if the working environment is a low, medium or high risk. This way, they are able to choose the right apparel for the job. Below is a detailed description of which class of HVSA to consider for different working conditions.

Low Risk:   Class 2, Class 1 depending on the actual conditions at the site

Examples of situations that could be considered lower risk:

  • Workers in activities that permit full and undivided attention to approaching traffic.
  • When there is ample separation between the worker on foot and the traffic.
  • When work backgrounds are not complex, allowing for optimal visibility.
  • When vehicles are moving slowly (e.g., less than 40 km/h).
  • When workers are doing tasks that divert attention from approaching traffic.

Examples of jobs include:

  • Directing vehicle operators to parking or service locations.
  • Retrieving shopping carts in parking areas.
  • Workers in warehouse operations.
  • “Right-of-Way” or sidewalk maintenance workers.
  • Workers in shipping or receiving operations

Example of Class 1 Apparel
Harness or Colour/Retroreflective Stripes on Other Clothing

NOTE: Other options are possible, including a shirt made of non-high-visibility material, but with high-visibility or retroreflective stripes/bands.

Medium Risk: Class 2 or 3 based on certain conditions

Examples of situations that may be of medium risk:

  • When vehicles or equipment are moving between 40-80 km/h (25-50 mph).
  • Workers who require greater visibility under inclement weather conditions or low light.
  • When work backgrounds are complex.
  • When workers are performing tasks that divert attention from approaching vehicle traffic.
  • When work activities are in closer proximity to vehicles (in or near flowing vehicle traffic).

Examples of jobs include:

  • Roadway construction, utility, forestry or railway workers.
  • Utility workers.
  • Survey crews.
  • Forestry workers.
  • School crossing guards.
  • Parking and/or toll gate workers.
  • Airport baggage handlers and ground crews.
  • Emergency response personnel.
  • Members of law enforcement.
  • Accident site investigators.
  • Railway workers.

Examples of Class 2 Apparel
Vests, Jackets and Bib overalls

NOTE: These examples are not the only options available.

High Risk: Class 2 for daytime, Class 3 for low-light conditions

Examples of situations that may be high risk:

  • Vehicle speeds exceeding 80 km/h (50 mph).
  • Workers on foot and vehicle operators with high task loads that clearly place the worker in danger.
  • When the wearer must be conspicuous through the full range of body motions at a minimum of 390 m (1,280 ft).
  • Work activities taking place in low light or at nighttime.

Examples of jobs include:

  • Roadway construction workers.
  • Utility workers.
  • Survey crews.
  • Emergency responders.
  • Road assistance/courtesy patrols.
  • Flagging crews.
  • Towing operators.

NOTE: These examples are not the only options available.

Conclusion

Just like any personal protective equipment, workers should be take through appropriate training on the use and care of the equipment. The following minimum information should be provided to workers wearing high-visibility apparel:

  • When to use the high-visibility apparel.
  • Fitting instructions, including how to put on and take off the apparel, if relevant.
  • The importance of using the apparel only in the specified way.
  • Limitations of use.
  • How to store and maintain the apparel correctly.
  • How to check for wear and tear.
  • How to clean or decontaminate the apparel correctly, with complete washing and/or dry cleaning instructions.

Remember; your safety should be your top priority.

FACTORS TO CONSIDER WHEN BUYING ELECTRICAL GLOVES

By Monica Ngage

Every day we wake up and go on with our daily hustles. Whether you are self-employed or employed; if not that you could be doing your daily chores in the house. But are we aware of the potential hazards that we expose ourselves to while executing our duties? Are there any precautionary measures in place to mitigate such risks?

You will agree with me that these measures exist but more often than not we tend to overlook them. Take for example an electrician, every day they risk getting shocks and burns from live wires; but this can be mitigated by use of electrical gloves.

Electrical gloves are used when working with high and low voltage applications to protect workers from shock, burns fires and explosions. To maximize their efficiency, they should be worn in threes; in the following order:

  1. Liner gloves-these are the normal gloves that we put on during the cold seasons. They reduce the discomfort of wearing rubber insulating gloves. Liners provide warmth in cold weather and absorb perspiration in the warm months. They can have a straight cuff or knit wrist.
  2. Electrical gloves-This is worn on top of the liner and are meant to protect the electrician from burns, shocks and explosions.
  3. Leather protector-they are worn over the electrical gloves to protect the gloves from swelling, tears, burns etc.It is important to note that the leather protector should always be shorter than the electrical gloves as shown on the diagram below

Electrical gloves are classified into two major classes:

a) Depending on the voltage that they can handle; the classes are shown in the table below:

ASTM D120 Class Specifications for Insulating Rubber Gloves
Class Chart Proof Test Voltage Max Use Voltage Label
Class 00 2,500 AC/10,000 DC 500 AC/750 DC Beige
Class 0 5,000 AC/20,000 DC 1,000 AC/1,500 DC Red
Class 1 10,000 AC/40,000 DC 7,500 AC/11,250 DC White
Class 2 20,000 AC/50,000 DC 17,000 AC/25,500 DC Yellow
Class 3 30,000 AC/60,000 DC 26,500 AC/39,750 DC Green
Class 4 40,000 AC/70,000 DC 36,000 AC/54,000 DC Orange

b) Depending on environmental factors they are resistant to; based on this, the classes are as follows:

  1. A – Acid
  2. H – Oil
  3. Z – O-Zone
  4. R – Acid, Oil and O-Zone
  5. C – Very Low Temperatures

Rubber is susceptible to the effects of the ozone, which can cause cracking and compromise the integrity of the glove. Ozone cutting/checking is a series of interlacing cracks produced by the action of ozone on rubber under mechanical stress. If the gloves are used in an environment where the levels of ozone are high due to pollution, ozone resistance is critical.

Once the electrical safety gloves have been purchased, OSHA requires that “protective equipment be maintained in a safe, reliable condition.” This requires that the gloves be inspected for any damage before each day’s use. Gloves must also be inspected immediately following any incident suspected to have caused damage. OSHA also requires that insulating gloves be given an air test along with the inspection.

In addition to the daily inspection, OSHA requires electrical safety equipment to be tested regularly. Rubber insulating gloves must be tested before first issue and every six months thereafter. They should be inspected for tears, holes, ozone cuts, swelling which is generally caused by chemical contaminants and any other defect. The testing is supposed to be done by OSHA accredited labs. If the insulating gloves have been electrically tested but not issued for service, they may not be placed into service unless they have been electrically tested within the previous 12 months.

To help ensure the integrity of the gloves and worker safety, gloves need to be stored properly when not in use. Proper storage means that gloves must not be folded and need to be kept out of excessive heat, sunlight, humidity, ozone and any chemical or substance that could damage the rubber.

DO’S & DON’TS

DO:

  • Follow company work procedures and safety rules
  • Inspect gloves daily for damage
  • Wear proper leather protectors over rubber gloves
  • Wash gloves with mild soap and rinse thoroughly with water
  • Let gloves air dry at room temperature or less than 120° F (49° C)
  • Store gloves in a protective bag

DON’T:

  • Wear jewelry or sharp objects when using rubber gloves
  • Wear damaged gloves
  • Store gloves inside out, folded, or ways causing stretching or compression
  • Store gloves near sources of UV, Ozone or heat
  • Allow gloves to contact petroleum-based products (oil, gas, solvent, hand creams)

A Sneak Peek Into The ‘Use Of Energy Audit Equipment’

By Karen Thuranira

Training is a very powerful tool to fuel the growth of any organization. Eenovators has trained over 500 professionals in the energy industry. 

In November last year, two of Eenovators consultants; Chris Mbori and Eng. Jabes Manyala landed in Entebbe Uganda on an exciting Friday evening, they knew they wanted to change the lives of a few sons and daughters of Uganda by doing what they do best; Energy Training!

What was the training about?

The Renewable Energy and Energy Efficiency Programme (PREEEP) of the German Federal Ministry for Economic Cooperation and Development (BMZ) had previously supported the training of 35 Certified Energy Auditors in Uganda through its implementing agency, Gesellschaft fur Internationale Zusammenarbeit (GIZ) GmbH in cooperation with Ministry of Energy and Mineral Development (MEMD).

GIZ-PREEEP identified lack of appropriate energy audit equipment as an obstacle to the capability of the auditors to offer professional audit services. They therefore went a step further and procured the necessary initial set of equipment and engaged Eenovators Limited to conduct energy audit equipment use for the auditors.

Who was trained?

The 35 Certified Energy Auditors (CEMs) were trained on the basic theory of the equipment applications and deployment then practical training conducted at two sites which had been arranged by GIZ.

The CEMs got a chance to use the various energy audit equipment, download measured data and analyze it using software for each equipment as applicable. They also learnt many soft skills such as the safety precautions required during energy audit, equipment use in order to assure safety of both equipment and personnel. They learnt skills required to identify different challenges in the field and how to find solutions using step by step analysis to arrive at the best options.

The equipment used for the training included;

  • Fluke Power Quality and Energy Analyzer Model 435-11
  • Fluke Power and Energy Logger Model 1736
  • Fluke Clamp Meter Model 376
  • Light Meter Model Extech AE 33
  • Greyline Ultrasonic Flow Meter Model TTFM-1.0
  • Moisture Meter Model Extech MO 260
  • Non-Contact Tachometer Model Extech 461825
  • Relative Humidity and Temperature Meter Model Extech RH 300
  • Ultrasonic Leak Detector Model I Leak 200
  • Flue Gas Analyzer Model TESTO 330-11 LL
  • Fluke Infrared Thermometer Model 572-2
  • Fluke Infrared Camera Tis 75

Benefit of the training

The main objective of this training was to train energy consultants on the use of energy audit equipment.  However, the participants benefited in the following ways as well;

  • They were able to clearly identify and classify the various types of energy audit equipment and other accessories
  • They gained a clear understanding of when and where to use the various energy audit tools
  • They acquired skills to enable them install, use, maintain and troubleshoot the various energy audit equipment
  • They were equipped with technical analytical skills based on data from the audit equipment.
  • They were equipped with technical report writing skills based on the data from energy audit equipment.
  • The trainers did an overview of health and safety in energy auditing, introduced the CEMs to energy auditing methodology and energy auditing instrumentation and measurements.

Participant Feedback from the Training

After the training was concluded, feedback from participants was collected and merged with the trainers’ observations. Below is a summary of the feedback;

1. There was information overload due to the many audit instruments participants had to learn how to use within a very short time. To avoid this, training can be conducted on related instrument clusters such as:

  • Power Quality instruments, Loggers and Clamp MetersThermal Imagers and Infrared
  • Thermometers, Flue Gas Testers
  • Ultrasonic Flow Meters and Ultrasonic Leak Detectors, etc.

2. A training on Data collection, data analysis and report writing should follow the audit equipment training as it’s an area of interest as well.

3. The surest way to understand how to use the large array of energy audit equipment is to deploy it practically. It is not enough just to go through the theory sessions only.

4. A better way to conduct energy audit equipment training programs is to first focus on specific areas of energy audits, for instance;

  • compressors and compressed air systems
  • Boilers and steam systems
  • Renewable energy systems (Solar PV, Solar water, etc.)

Studies have shown that the most successful organizations have attributed their success to employee training. Training is the sure key to unlock an employee’s potential, improve on their skills and give them the confidence to make a difference. This in turn, leads to great success for both the employee and the organization. 

POWER AND ENERGY LOGGER REVIEW – PEL 103

By Ruth Carol Atieno

The Power and Energy Logger (PEL 103) is used for data logging for most 50 Hz, 60 Hz, 400 Hz and DC distribution systems, with many connection possibilities. It is designed to work in 1000 V CAT III and 600 V CAT IV environments.

It has other specifications and I will discuss each of them in detail.

Easy Mounting

The PEL 103 has magnets at the back which makes it easy to mount it on the distribution board to be measured. It can therefore be placed away from the cables for easy access and visibility.

Memory Capacity

The PEL 103 works well with FAT32 formatted SDHC cards of up to 32GB in size. It is also recommended to do the recording using the categories below;

  • One week when the recording includes the aggregated values, 1-second data and harmonics.
  • One month when the recording includes the aggregated values and 1-second data but not the harmonics.
  • One year when the recording contains only the aggregated values.

Communication

It provides four communication options. USB, LAN and Bluetooth.

Communicating remotely with the PEL 103 using an Ethernet connection makes it easier and quicker to send a client important feedback when needed rather than having the device at hand. This is a time saver as the data recorded by the PEL 103 will be readily available from a computer and no time is spent travelling to and from sites to retrieve data.

The Bluetooth feature will enable you to connect it wireless to a smartphone or tablet. You can therefore set up, monitor and retrieve recorded data from the device without being attached to it physically.

BATTERY

The PEL 103 also comes with a rechargeable NiMH battery with the following specifications;

  • Long battery charge life for a limited volume and weight.
  • The battery can be recharged even when it has not fully discharged.
  • An environmentally friendly battery.

LCD Display

The bright blue triple LCD display also provides visuals for a variety of parameters such as Voltages, Power, Currents, Energy etc.

Measurement Factor

Looking at the measurement factor, the PEL 103 offers the following;

  • Direct current measurements from 50mA up to 10,000A with MA193 external current sensors
  • Power measurements: VA, W and var
  • Energy measurements VAh, Wh (source/load indication) and varh (including quadrant indication)
  • Power Factor (PF), Cos (Φ), and Tan (Φ), Crest Factor, Total Harmonic Distortion (THD) for voltages and currents
  • Harmonics from the fundamental signal up to the 50th order for 50/60Hz voltages and currents
  • Frequency measurements
  • RMS and DC measurements @ 128 samples/cycle – each phase simultaneously

Best Head Protective Gears

By Ruth Carol Atieno

The skull is one very important part of the body because it protects the brain from any external shocks. And for us to ensure more protection, depending on our location or activity at any given time, we must have on our heads extra protective gears. For those of us who visit construction sites, cycle, ride motorbikes, are rock climbers etc.

In this blog I will talk about various activities, locations and what kind of protective head gears are best suited for each.

Bump Caps

Bump caps are best suited for electricians, those of us visiting construction sites etc. It has the capability to protect your head from any impact or external shocks.

Apart from it’s protective features, the design also looks really nice and eye catching.

Hard Hats

Hard hats are know by many. They are very popular and you would not miss one in a construction area. They are very suitable in a construction environment or any site that is prone to head injuries.

Motorbike Helmets

For the lovers of speed bikes, sport bikes or generally motorbikes a helmet is a necessity. To avoid severe injuries of the head, wearing a helmet is key. Not only the riders but also the pillion.

A motorcycle is way too open to ride on it without any protective gears. In this category, there is a variety of helmets, even fancy ones. It’s all on you to pick how you want to safely rock your motorbike.

Firefighter Helmets

A building on fire will be reduced to small pieces and often there will be things falling off. This is why firefighters always have their firefighter helmets on, to protect their skulls from falling blocks or stones and also from the high temperatures.

Baby Head Guard

Well we must also factor in the young ones in this head protection topic. A baby is not always aware of what risk he/she might be putting him/herself into. And therefore a baby head guard is very important.

They might bump their heads during a fall or even while crawling hit their heads on a furniture.

A baby’s skull is still in a developmental stage and therefore might not be able to protect the brain from even the slightest impact.

Bicycle Helmet

For the workout lovers or cyclists in general, bicycle helmets come in handy as a fall might occur. The helmet will reduce the dangers of an impact on the head.

There are various designs and one can find cool or fancy helmets. Rocking your cycling in style huh!?

Children learning how to cycle also must have bicycle helmets for children on as they are prone to falls.

Rock Climbing Helmets

Adventure is fun I must agree, but while at it ensure you are well protected and out of danger. For the lovers of heights, protecting the head is very important and this is where rock climbing helmets come in.

You will have reduced the risks that might occur in the event of a fall or a head bump.
