Anyone who works with electricity knows how important it is to be aware of potential safety hazards. These hazards include shock, arc flash heat and explosions that can take place due to electrical mishaps. Predicting the level of hazard can be calculated thanks to the NFPA 70e Standard for Electrical Safety in the Workplace.

The NFPA 70e was officially adopted by OSHA and is now a standard that employers and employees must abide by, in addition to ensuing all electrical equipment complies. This compliance is required on any equipment emitting over 50 volts and can effect solar DC systems and UPS batteries.

Electrical safety standards are constantly improving and the NFPA 70e committee updates their standards every few years. David Weszely of Lewellyn Technology highlights changes to the standards for the upcoming year in his article: The Most Important 2018 Changes in NFPA 70e.

Here’s a synopsis of his review:

• A qualified person will need to complete a Job Safety Analysis (JSA) before work or troubleshooting is performed.
• Adding a personal protective equipment (PPE) conformity assessment to promote consistency.
• Arc flash and shock hazard risk assessment now include the “potential of human error.”

Weszely suggests that companies make sure all qualified workers have access to the 2018 NFPA 70e standard, update their electrical safety program and schedule on-site NFPA 70E electrical safety training.

Although prefabrication methods have been used for centuries in the construction industry, they are new to the electrical industry. Prefabrication, which means to construct in advance, is the practice of connecting components in a warehouse and delivering completed or partially completed units to a construction site for installation. Building in a controlled environment adds value in many ways and increases safety by limiting work in elevated areas.

As electrical contractors search for new ways to increase productivity, some are beginning to develop prefabricated electrical systems to expedite installation and increase their ability to take on more sophisticated and complex projects. Electrical prefabrication includes a wide variety of components from switches and receptacles to internal floor and wall equipment.

BENEFITS OF ELECTRICAL PREFABRICATION

• Increased Installation Efficiency: Electrical assemblies are built to exact specifications, so once they are prefabricated and delivered on-site, they simply need to be connected to the electrical supply to start working, greatly increasing efficiency. This also limits lost time retrieving forgotten tools and materials since most of the work is already complete.
• Less Material Handling: Prefabrication eliminates unnecessary material handling on the job site. In traditional construction, materials are moved from room to room as individual assemblies are built.
• Reduced Labor Costs: By performing repetitive installations your team requires less time, saving you labor costs.
• Faster Turnaround Time: With finalized plans, equipment can be prefabricated before the building is even built, which can shorten the project timeline
• Higher Quality: Eliminating the negative impact of weather and other trades by prefabricating in a controlled environment allows for higher quality output.

RK Electrical can design an entire prefabricated electrical system for your project or simply build and deliver stand-alone assemblies. Our team will evaluate each project to find you the most cost-effective solutions. We also provide preconstruction services, which can decrease the time and labor required to complete the project.

Energy consumption is on the rise and consequently, more expensive than ever. As the demand continues to increase, scientists and engineers are exploring new ways to increase efficiency and safety in systems that require a lot of energy; HVAC systems are no exception. In recent years, groundbreaking technologies began giving consumers the ability to reduce the energy consumption of HVAC systems in our homes and buildings. While many new technologies are still in the early stages, several have been widely adopted. Here are the top innovations taking over the HVAC industry.

TOP 8 HVAC INNOVATIONS:

• Movement-Activated Air Conditioning automatically turns off in empty rooms
• Thermally Driven Air Conditioning relies on solar power for cooling
• Ice-Powered Air Conditioning turns cool water into ice overnight, to be used the following day thus reducing peak electrical demand.
• Dual-Fuel Heat Pumps work hand-in-hand with a gas-fired furnace
• Geothermal Heat Pumps transfer heat to or from the earth
• Sensor-Enhanced Ventilation can control when an exhaust fan needs to run
• Air Purifying Technology allows the removal of nearly all of the particles from the air stream
• Energy Analysis Software allows for constant monitoring and adjustments to achieve optimal efficiency for HVAC systems

By using cloud-based systems and increasing smart and real-time communication between mechanical units, HVAC controls will continue to become more energy efficient and allow for cost savings. Energy alternatives, such as solar and geothermal will become more commonplace and technology like smart thermostats will become more popular by reducing energy consumption.

Testing Welding Candidates Before Hiring is Key

Quality and safety are top priorities when it comes to steel fabrication. In order to produce high quality products, it is important that steel fabricators test welding candidates before they are hired. Some companies will even retest certified candidates to ensure they meet company requirements.

The most efficient way to test welders is to have the capabilities to do so in-house. That said, there are few steel shops in Colorado that test in-house. The majority of shops send their tests to an outside source; results can take over a week to get back and can cost around $20,000-30,000 a year.

Companies that test in-house save time and money with certified weld testers that can review four to five tests a week. On average, two out of five candidates pass and move onto the interview process.

Tests and Standards for Welding Candidates

A 6G test consists of a 2” pipe weld. The test takes an hour and is examined with side bends. Some companies perform an industrial radiography test to examine the internal structure and integrity of the weld.

The structural steel tests are the 3G, vertical position, and 4G, overhead position. These tests go through a four-hour process starting with the visual test. During this test, the inspector looks for any discrepancies or holes that would compromise the end product. The coupon then goes through a root bend and cap bend test. If the candidate passes the bend tests, they are certified, and deemed a good candidate for hire.

Inspecting Steel Before It’s Installed on a Project is Required

Even with a team of certified welders fabricating steel projects; on-going special inspection requirements are necessary for all projects. These inspections are done by an outside party unless you are an AISC certified fabricator and erector, which employee certified testers to perform in-house inspections.

RK Steel is a premier shop for end-to-end design, fabrication and erection of structural steel and miscellaneous metals. RK Steel abides by the AWS Structural Steel and ASME certification standards. We pride ourselves on weld testing candidates before interviewing. Contact us to discuss your steel needs.

Managing mechanical systems involves a deep understanding of the design, construction, operation and maintenance of the equipment. Asset management relates to the management and enhancement of those mechanical systems.

Importance of Optimal Mechanical Systems

Mechanical systems are comprised of pumps and filters, among other equipment, that are responsible for the efficient flow of liquids and air throughout buildings. They provide water, heating, cooling and ventilation for occupants and remove waste from the building.

The operation and maintenance of mechanical systems are labor intensive and require a technical skill. While mechanical systems can contain components that are hidden inside walls or under floors, most key equipment is located in a utility room that is easily accessible for upkeep. To preserve mechanical assets over their life cycle, regular monitoring of equipment and maintenance needs to be performed, preferably by a certified technician. Large equipment that fails, such as a burst pipe, require urgent repair, as this type of failure could lead to flooding or loss of hot water for tenants.

Asset Management Challenges

Keeping tabs on mechanical assets can be a daunting task as they require extensive record keeping. Because mechanical systems contain many moving parts, they typically have the longest list of assets in the asset inventory, ranging from fans to boilers and pumps. Often, basic supplies are kept on-hand in mechanical rooms, such as replacement filters, but some buildings also have supply rooms for additional spare parts. All of these items, from large equipment to spare parts, need to be accounted for and tracked. Documents must be kept readily available for quick reference in day-to-day operations.

Tracking with Technology

Today, technology has enabled service providers to inventory and track all mechanical assets on a cloud-based platform with easy to use customer interfaces. Warranty status, repair and maintenance history, upcoming scheduled events and end-of-life (EOL) forecasts are all recorded and accessible from a single source.

The national unemployment rate is at a shocking low of 4.4% due to growth in the manufacturing, construction, professional and technical services, health care and mining industries in 2017. This statistic indicates that the country’s economy is healthy with increased production, more jobs, steady consumer spending and less government involvement, making it hard for people to recognize the strain so many companies are currently facing due to the shortage of skilled trades employees.

Businesses in the manufacturing and construction industries have more open positions for plumbers, pipefitters, welders, electricians, technicians than qualified candidates to fill them. In fact, the skilled trades is currently the hardest segment of the workforce for employers to staff, and the gap is expected to widen. Following are three reasons leading to the gap between open positions and available employees:

1. Commercial Construction Market on the Rise
   The construction industry is expected to grow, or remain stable, in the next 12 months according to the USG Corporation + U.S. Chamber of Commerce Commercial Construction Index. The latest index score of 73 is based on three main factors: backlog, new business and revenues – meaning, the outlook for the commercial construction industry is strong and the need for qualified trades workers remains high. Companies affected by the continued market growth are fighting to hire from the same limited pool of skilled trades employees.
2. Aging Workforce
   Manufacturing and construction work can be tough due to the physical demands of the job. Most skilled trades workers can’t sustain the stress to their body much past age 65, with most employees retiring between 55 and 64 years of age. Right now, 53{daeb8d662f58e4975bc93960761d671bdf0aa2ad049ea8a375d2717d280ef80b} of skilled trades workers are over the age of 45 and for every one skilled trades employee who enters the workforce, five retire.
3. Stigma Around Skilled Jobs
   High schools, student counselors and parents are conditioned to believe that academic prep for college is the best way to go. There is a stigma that skilled jobs are low-paying and offer little advancement, but that does not hold true today. Although some parents would prefer their child to become a doctor rather than a plumber, the truth is that skilled jobs earn a good living and offer real career paths – often into white-collar management roles – and without college debt. However, this stigma results in few young people being interested in pursuing skilled professions. There are now defined pathways to bachelor degrees by starting out in an accredited apprenticeship program. Apprentices now have stackable credits that can be deployed if they choose.

Training and Awareness Alleviate Labor Shortage Pressure 

Vocational schools offer students a fast-tracked career path, typically two- or four-year programs, into a high demand career without student loans. Apprenticeship programs, like the RK Apprenticeship Program, offer students training in plumbing, pipefitting, HVAC, sheetmetal, ironwork, electrical and structural fabrication while working as a full-time employee with benefits and opportunities for advancement – plus, apprentices can earn up to 45 credit hours towards an Associates in Applied Sciences (A.A.S.). 

RK knows that you cannot build a business off of buying talent and believes that we must attract and train the next generation of skilled labor through work-based learning not only for our own success, but also for the future success of the manufacturing and construction industries. We continue to make significant investments in training and developing our talent pool through in-house training programs and by raising awareness. Check out our free whitepaper on the Swiss Apprenticeship model and see how RK is incorporating similar practices.

Over the next two decades, energy consumption is expected to increase by 30%, according to Oil & Gas Journal, meaning the need for better energy efficiency is necessary to keep up with our power-dependent lifestyles. To move towards a more energy-efficient future, corporations need to measure how effectively their electricity usage is through power factor.

WHAT IS POWER FACTOR?

Power factor is the ratio between the real power (what is used for heating, lighting, etc.), reactive power (what is pulled to create magnetic fields) and the apparent power (real and reactive power combined) consumed by an alternating current (AC) electrical system.

Power factor measures how efficiently electrical power is converted into useful output. Ideal power transmission is 100% efficiency or a power factor of one, anything less means that additional power is needed to achieve the same task. Unfortunately, a power factor of one is nearly impossible to sustain. Electrical devices connected to a network may use or produce power, causing variation in the power factor. If the variation isn’t corrected, higher currents are pulled from the network which can lead to:

• Grid instability or an imbalance between production and consumption of energy
• Higher fees from utility providers
• Diminished transmission capacity

Major causes of poor power factor are inductive loads on equipment. Inductive loads resist changes in current and create lag.

HOW IS POWER FACTOR CORRECTION PERFORMED?

Adding power factor correction capacitors to the electrical system is the simplest way to improve the power factor. These capacitors act as reactive current generators, which help to offset the non-working power used by inductive loads and improve the power factor. Capacitors are cost-effective, easy to install and the return on investment is typically achieved within one to two years of usage.

WHAT ARE THE BENEFITS OF IMPROVING THE POWER FACTOR?

The power distribution system in a network can be overloaded by excess current. Improving the power factor can offer many benefits, including:

• Lower electric bills by eliminating utility penalties for a poor power factor
• Improved energy efficiency due to reduced power losses
• Increased capacity of the current
• Improved voltage to equipment
• Environmentally friendly – less power needs to be generated, so less CO2 is produced
• Increased lifecycle of equipment with less heat generation within cables, switchgear, transformers and other equipment.

An arc flash is a type of electrical explosion that occurs when electric current travels through the air between two conductors or a conductor and the ground. More specifically, the arc flash is the heat and light created by an electrically energized arc.

What Causes An Arc Flash?

• Accidentally touching the wrong surface or dropping a tool
• Sparks from breaks or gaps
• Equipment failure from faulty installation or normal wear and tear
• Dust, condensation or corrosion

What Are The Dangers?

Arc flash injuries can be violent and often cause serious injury and even death.

FIVE MOST COMMON DANGERS TO WORKERS

• Being thrown to the ground, blown into a wall or off a ladder by large shock waves
• Concussions that cause loss of memory or brain trauma
• Ruptured eardrums due to the deafening blast can cause hearing loss
• Receiving a strong shock by accidentally touching energized conductors
• Skin burns caused by heat from the blast

Because of these dangers, The National Fire Protection Association (NFPA) has developed specific approach boundaries designed to protect employees while working on or near energized equipment. The further from a potential blast that a worker is, the lesser chance they have of being severely injured.

Facility managers and safety teams should work together to explain risks to employees.

Qualified employees should always wear appropriate personal protective equipment, use insulated tools and follow safety precautions when performing work on electrical equipment. The overall most effective way to eliminate the risk of an arc flash is to de-energize equipment before working on it.

DANGERS FOR BUSINESS OWNERS

It is in the best interest of business owners to regularly maintain their equipment, continue safety training for employees and provide appropriate safety precautions for anyone working with electrical equipment. Some of the most common dangers for business owners resulting from an arc flash are:

• Fire spreading throughout the building/property
• Damage to nearby equipment due to flying objects from the blast
• Extreme heat melting materials and equipment
• Increased costs due to employee injuries and equipment damage

NFPA 70E Electrical Safety Compliance standards require building owners to complete an ARC flash risk assessment on the facility’s electrical distribution system to minimize the risk of arc flash, shock hazards and injuries. RK Electrical can conduct these complex studies and provide the reporting you need for safety compliance. Contact us at rkelectrical@rkindustries.com to schedule a risk assessment.

Facilities management is the maintenance of buildings and equipment. It’s a complex and difficult job which is necessary to support and help improve the effectiveness of any business. Effective facilities management aids in providing a safe and efficient working environment; and contributes to the delivery of strategic and operational objectives.

FACILITIES MANAGEMENT GOALS

Facilities teams often lack the appropriate resources needed in order to meet their facilities management goals. Many times they are overworked and can’t keep up with routine maintenance. They are too busy handling day to day duties and emergencies, requiring outside assistance in order to get back on track.

FACILITIES MANAGEMENT PARTNERSHIP

When companies need assistance reaching their facilities goals, they create a facilities management partnership. A strong partnership can formulate and realize the overall facilities management strategy. While there are many benefits to utilizing a facilities management partnership, these are the top five.

1. ASSET MANAGEMENT
   Keeping tabs on each mechanical asset is a daunting task. Today, technology has enabled service providers to inventory and track all mechanical assets on a cloud-based platform with easy to use customer Warranty status, repair and maintenance history, upcoming scheduled events and EOL forecasts are all recorded and accessible from a single source.

2. LONG-TERM CAPEX/OPEX BUDGET PLANNING
   Are you haunted by budget planning season? Eliminate the element of surprise with your CFO by creating a ten-year budget plan based on asset life expectancy. The cost of repairs and replacement are inevitable, the surprise doesn’t need to be.

3. STAFFING AUGMENTATION
   Hiring additional full-time employees can be very time consuming and expensive. A facilities management partnership reduces your staffing needs by allowing you access to licensed engineers and technicians when you need them for significantly less money and headache.

4. SCHEDULED SERVICES

Colorado is known for its severe spring and summer storms, and they typically include large hailstones. Hail forms when updrafts in thunderstorms pull rain up into frigid areas of the atmosphere where they freeze into ice pellets. When the storm can no longer support the weight of the hailstones or the updraft weakens, the hail falls to the ground. The larger the hailstones, the more damage they can do.

Hail can cause serious damage to a building’s roof or ground-mounted machinery and equipment. It often damages the facility’s condenser unit, reducing its ability to dissipate heat. This excess heat not only greatly reduces building efficiency and creates unhappy occupants, it is likely to cause the compressor and condenser fans to fail, resulting in much higher repair costs.
