Keep Safe with PIP Personal Protective Equipment

Working with metal can be dangerous. Just ask any metalworker who has ended up with a floater in their eye or a knuckle chewed up by a coarse grit abrasive belt.

Metalworkers can protect themselves from sparks and swarf with PIP safety equipment.

For metalworkers and machinists of metals and other materials, Steiner offers a large selection of personal protective equipment (PPE) from Protective Industrial Products, better known as PIP, that can help protect the head, face and hands from this swarf.

 

Keep Safe with PPE

Grinding, chiseling, sanding, drilling, sawing, welding and undertaking other machining processes produce metal shards and chips that can fly in unexpected ways and in any unexpected directions.

According to OSHA, an estimated 9 out of 10 occupational related eye injuries could be avoided through the use of proper safety equipment.

PIP headgear provides crown protection and can utilize various face shields. Shown here is a clear PETG, universal fit safety visor.

For the face and head, a combination of safety glasses and face shields protect the eyes and face from flying particles, hot sparks, liquid chemicals and vapors.

PIP headgear for face shields provides crown protection, especially in grinding applications and can be fitted with PIP Bouton® Optical face shields. These protective visors provide clear, crisp and distortion-free visibility.

Features of the face shields, include:

  • Impact resistance and protection from projectiles and splashing liquids.
  • They can withstand extreme hot and cold temperatures in heavy-duty applications.
  • They can be worn with standard headgear or fitted to a hard hat.
Safety Glasses
PIP’s Recon safety glasses are rimless and feature anti-scratch and FogLess® 3Sixty™ coating.

Face shields and PIP Bouton® Optical safety glasses can  be used in combination to protect the face from hot sparks in grinding, chiseling, welding and other applications. In some cases, it is recommended that they be used in concert such as to protect the worker from chemical, fine mist or even molten metal splash.

According to OSHA, safety eye wear should be worn as the primary eye protection against impact from flying fragments, objects, large chips, and particles created during grinding, sawing, drilling, fastening, and sanding applications.

PIP’s eyewear products, which meet UL and CSA requirements, are available in almost 50 distinctive shapes of safety eyewear for the right fit and have numerous features geared for the application.

Models include the Recon rimless safety glasses with a gloss black temple and gray lens, and the Recon rimless safety glasses with clear temple and clear lens.

Also available are the Fuselage full-frame safety glasses with black frame and soft padding, that come in either gray lens or clear lens.

Fuselage full-frame safety glasses feature foam padding to keep out dust and debris

Features of Bouton Optical safety eyewear include: anti-scratch and anti-fog coatings for indoor and outdoor applications; multiple lens color options for specific industrial applications, lighting conditions and work environments; and soft foam padding that forms a comfortable seal to keep out dust and airborne particles.

PIP offers safety glasses that can also alleviate the problem of fogging, which is a dangerous, and irritating, problem familiar to most metalworkers. Lenses fog for many reasons, all of which are related to ambient temperature and moisture in the air. When a rapid temperature change occurs, moisture in the air collects on untreated lenses, causing the lenses to fog and impede vision.

To solve this problem, many Bouton optical glasses from PIP are available with Fogless® 3Sixty™ Technology. These include the Fuselage and Recon models. This will prevent fog when transitioning between warm and cool environments, working in a humid or wet environment, combining eye protection with respiratory equipment, or just sweating from hard work.

Hand Protection
The MaxiFlex features a Micro-foam grip that provides good grip and resists abrasion.

Cuts to the skin from metal shavings and other swarf are another common injury endured by mostly anyone that has machined metal.

Some people are also susceptible to allergies caused by the resin-impregnated fiberglass on abrasive disks used in grinding operations.

PIP gloves provide protection from sparks and fragments of disk and waste metal thrown out by the disk. They also protect your hands from general wear and tear, i.e. minor cuts, scuffs, abrasions and potential allergies.

The seamless knit PolyKor X7 Blended Glove with NeoFoam coated palm and fingers are cut resistant and are touchscreen compatible

Some metalworkers believe that gloves can affect the “feel” they have for the bevel and reduces their ability to grab hardware and tools or utilize touch screens on controllers.

PIP has those problems covered as well.

PIP offers a large range of sizes from small to double extra-large for a great fit, which is important when working around rotating equipment.

The gloves offer a range of features. They are high-cut, puncture and abrasion resistance; they are resistant to chemicals, water and ultraviolet light; provide superior grip in wet and dry conditions; are touchscreen compatible, and feature knit wrist to prevent dirt and debris from entering the gloves.

Glove brands include the Maxiflex® Ultimate™,which is a seamless knit nylon/Lycra glove that features Nitrile coated Micro-Foam Grip – Ad-Apt™ Technology that keeps hands drier and cleaner. The Nitrile coating provides good grip and abrasion resistance.

PIP’s G-Tek® Polykor® X7™ glove is a seamless knit Polykor® X7™ blended glove with Neofoam® coated palm and fingers and is touchscreen compatible. The PolyKor blended shell with X7 technology offers high-cut resistance and the knit wrist style keeps out dirt and debris from the glove.

The Ambi-Dex Grippaz Skins have a textured fish scale grip for extra traction with wet and oily parts.

The Ambi-Dex® Grippaz™ Skins is an ambidextrous Nitrile glove with textured fish scale grip (6 Mil) that provides extra traction with oily or wet parts, and has a rotated thumb grip for secure precision grip of small parts.

So, choose from a selection of gloves that are designed to protect your hands from harsh metalworking operations, and give you a good grip, no matter the application and don’t forget to protect your head and face with PPE from PIP.

Schneider Electric Provides Safety Switches For Infinite Applications

Schneider’s Square D Safety switches are vital components to safety and power control. They are a means to disconnect from the electrical load and provide protection to the branch circuit.

When necessary, they can be used to disconnect manufacturing equipment, heavy machinery and light commercial and residential applications from its power source. Users may need to disconnect equipment from its electrical supply for a variety of reasons from scheduled preventive maintenance to emergency stoppage.

The performance of safety switches is important to the safe operation of many industrial applications. In addition, requirements from a variety of organizations  have increased the use of safety switches in many commercial and industrial facilities.

In addition, safety switches are an NEC requirement in industrial and manufacturing facilities.  For instance, a safety switch must be in sight from all motors or manufacturing equipment and not more than 50 feet from the equipment it controls.

A key performance benefit of the Schneider safety switch is its ability to break load. A locked motor can draw six to eight times motor full-load current. In an emergency situation, it’s important to have a safety switch with enhanced load-break features such as those featured in Schneider’s switches. A key element of Square D safety switches is its blade and jaw construction that has been designed to manage heavy motor loads and arc interruptions.

Multiple types of disconnect switches are available, and the switch that work for you depends on a number of factors in your working environment.  Steiner’s expertise can help make the appropriate choice. Steiner stocks a large inventory of safety switches ready for pickup at one of our convenient locations or on-time delivery to your facility or job site, including: general duty, heavy duty and double throw switches in single and multiple pole, fusible and non-fusible.

Here is a look at some of the most common safety switches.

General Duty Safety Switch

Make Selections EZ

These safety-switch options, and others that are more specific in application, come with multiple options such as various difference in amperage and voltage. In some cases, the question is whether to use fusible or non-fusible switches.  Fusible safety switches combine fuses with the switch in a single enclosure. For both fusible and non-fusible safety switches, when the circuit is open, the safety switch disconnects the load from its source of power, while closing the circuit reconnects the load.

The Schneider Electric Safety Switch EZ Selector can guide you to the most appropriate safety switch for your required application.

Siemens SINAMICS V20 Drives Minimize Costs and Maximize Efficiency

When it comes to variable frequency drives, tradeoffs may need to be made. How much power do you need? How much space do you have? The  SINAMICS V20 family of AC drives might just be the answer to these typical questions.

These Siemens-produced, SINAMICS branded VFDs come in a variety of frame sizes and output ratings for when you need a low-power drive to smoothly start and stop a motor or to control speed and torque during operation of an increasing number of a basic motion sequences.

The SINAMICS V20 AC drive family is an economical, compact, rugged and reliable group of drives that bring versatility, and ease of use and installation to 40-hp and under plant and machinery construction, individual automation, and drive solution applications.

SINAMICS V20

With seven frame sizes, the SINAMICS V20 can be individually adapted to the particular application or user requirements using various options such as an external Basic Operator Panel (BOP), connecting cable, filter, braking resistors, shielding, and more.

The power range is:

  • 0.12 kW to 30 kW (1/6 hp up to 40 hp).

The voltage range is:

  • 1AC 200V … 240V (–10% / +10%)
  • 3AC 380V … 480V (–15% / +10%)

The newest and smallest of the SINAMICS V20 family of drives are the FSAA and FSAB models that save more than 30% in mounting space compared to the previously smallest model, the SINAMICS’ FSA model (90 mm (3.5 in.) x 150 mm (6 in.)) . With a width of just 68 mm (2.7 in.) and a height of 142 mm (5.6 in.), the AA and AB models both have the same footprint, but different heatsink depths.

The SINAMICS V20 Quick Selection Guide can help yo determine the most appropriate V20 drive for your application.
The SINAMICS V20 Quick Selection Guide can help you determine the most appropriate V20 drive for your application.

The V20 family of rugged devices, which are IP20 rated and can be EMC filtered, are tailored for operating pumps, fans, compressors and conveyor belts as well as for basic drive applications in the process and manufacturing industries.

Ease of use and installation

One of the V20’S benefits is ease of installation. The units can be wall mounted, push through mounted for efficient cooling, and side-by-side mounted to reduce required cabinet space. Typically, drives need to be 2 in. apart for cooling purposes, but with heat sinks located judiciously to release heat through the top and bottom of the unit.

The unit itself is easy to use. A Parameter Loader makes it easy to program and speed up commissioning. This modular, plug-and-play device easily installs to the face of the drive. The device uses a memory card that allows more than 100 parameters to be installed such as motor specifications, voltage, current speed, application deceleration rate acceleration rate and other pertinent data, says Jovan Cetkovic, Motion Specialist with Steiner Electric.

Additionally, “cloning” is possible by installing the same parameter loader on different drives.

Without the parameter loader, users access a basic operator panel on the face of the drive. Utilizing the BOP, all parameters can be programmed giving the user full control of the drive in terms of speed and other factors.

In addition, there are terminals on the face of the drive that allow for direct wiring for analog I/O control.

The SINAMICS’ V20’s feature a Keep Running Mode that keeps the output load running even in the event of power fluctuations, overvoltage, overcurrent, or other power stability issues.

Energy savings is achieved in several ways. For instance, the SINAMICS V20 drive makes it easy to save money through the use of an ECO mode that ensures that the motor current is automatically adapted to the load state. In addition to that, the drive is capable of DC bus couplings such that a drive regenerating can share power with other drives.

The drive also features a Hibernation Mode that reduces energy consumption when the drive is not in active use.

It also features an integrated braking chopper from 7.5 kW to 30 kW (10 hp up to 40 hp). When a motor is de-energized and coming to a stop, it changes from a motor to a generator producing energy. Resistors dissipate energy so the VFD’s capacitors are not damaged. This power can also be used during drive regeneration.

The V20 drive family has a number of accessories that can be used. For instance, a new extension module is available to increase the number of inputs and outputs of the SINAMICS V20 400V converter.

Mounted onto the converter, the module provides 2 additional digital inputs and 2 relay outputs to the converter. The module increases functionality. For example, it can now be used for multi-pump control, where one V20 can control a maximum of four pumps.

Equipped with connection ports on its front- and backside, the module may be used in combination with other accessories of the SINAMICS V20 such as the BOP, the BOP interface, and the Smart Access web server.

Worldwide access
The SINAMICS V20 Smart Access webserver module option is mounted on the converter. It allows wireless commissioning and operation via smartphone, tablet, or laptop.

SINAMICS V20 Smart Access is a tiny drive-mounted web server module that turns a mobile device or laptop into a virtual operator panel, allowing it to commission, operate, diagnose, and maintain the AC drive.

An embedded graphical user interface (GUI) enables easy use of the SINAMICS V20 in every phase of operation.  It requires only a few steps to set-up and no installation or download of additional software is needed.  The onboard Quick Set-up Wizard provides users a fast and easy commissioning procedure, enabling all the following: motor data can be entered and checked, connection macros for digital inputs/outputs can be activated, application macros can be selected and activated for pumps, fans, compressors and other devices plus the common and frequently used parameters on the drive can be set for motor start, acceleration, deceleration, and min./max. speed.

Elk Grove to Japan, Steiner Delivers

Imagine you’re sitting in your office, and your corporate headquarters contacts you and tells you they’ve had an emergency shutdown and they need you to get them some critical parts by the next day. But, you realize that you don’t have the parts in stock and besides, corporate headquarters is on the other side of the world more than 6,000 miles away.

What do you do?

The first thing you do is call your sales representative at Steiner Electric and ask for help. In this case, Matt Piekarczyk and Rich Meagher, both inside sales representatives, went into emergency order mode and ascertained that we had the needed parts. They then turned to Jose Gonzalez and Rigoberto Gonzalez in the warehouse department and Jim Boss in shipping to locate, box and prepare the parts for shipping. In all, 3 boxes of much-needed parts were transported.

“From sales to shipping to the customer, it was a group effort,” says Boss, “Even the customer had to create original labels and get them to us so that they could be shipped via FedEx for next day shipping to Japan.”

It is this type of effort, this desire to help a customer—no matter the challenging circumstances—that sets Steiner apart from other distributors. And, it is this effort, this willingness to go that extra mile (or in this case 6,000 miles), that keeps customers coming back to Steiner to help them with their business and supply needs.

In fact, a few days later, the customer, a reseller of industrial machinery and related equipment, placed another overseas order with us. This time, the deadline was not as immediate, but that doesn’t mean that the Steiner team didn’t go above and beyond again.

“Without being asked, we made sure that this order was shipped to Japan on heat-treated skids,” says Boss. Heat treated-skids are heated to a core temperature of 140 degrees for a minimum of 30 minutes to kill off any insects or larva that might be in the pallet. “The use of heat-treated skids should be routine for any company that ships out of the country, but some companies don’t do it,” he adds. “I know about it because of all the freight that I have shipped out of the country over the years.”

For help with any order a Steiner representative is always just a phone call away. If you are in need of emergency services call the 24-hour service line at 1-800-STEINER (783-4637).

Understanding The 5-Step Process to Mechanical Safety

With the increasing use of automation, requirements for protecting machinery and operators have evolved and become more complex. The improper use of machines can lead to safety hazards when the correct operating protocols are not followed. Thankfully, advancements in technology have allowed for integration of protection devices into the work process, helping to reduce safety risks and improving productivity.

In this blog we’ll define machine safety and take a look at the 5-Step Process to Safety, as well as look at ways of assessing risk, which was originally presented by Fortress Interlocks at Steiner’s 2016 Automation Technology Summer Symposium.

Defining Safety and Assessing Risk

Safety is the freedom from unacceptable risk as defined in IEC 62061 with respect to machinery operation. This provides a definition of safety in terms of risk, and makes clear the importance of assessing risk to achieve safety. [i]

Since the key term in the definition is “unacceptable risk”, a value on a range that determines the threshold between acceptable and unacceptable needs to be established. Various standards can provide guidance on how to determine when acceptable risk has been achieved. Keep in mind that acceptable risk may differ between organizations, so this value is not purely defined in any standard or methodology. The main takeaway is a threshold should be identified prior to starting a risk assessment.

risk-graph

 

We can also define risk in terms of the following equation.

The severity of possible damage + the probability that it will occur = risk in terms of the respective hazard.

To measure the probability, we would need to look at a few factors:

  • frequency and duration of exposure to the hazard
  • available options for avoiding the hazard
  • the probability of an event that can cause the damage to occur

Breaking Down the 5-Step Process to Safety

Step 1: Risk or Hazard Assessment – This initial step requires the limits of machinery to be determined. Next, the hazards are to be identified, followed by estimating and evaluating the risk. Once all these items have been established, if the risk has been adequately reduced, the first step is considered complete.

1st-step-5step

Step 2: Safety System Functional Requirements After assessing the risks, the next step identifies how the machine is supposed to operate in each mode of operation for each person that uses the machine. It identifies special modes such as safe-speed, zone control, etc. In other words, the second step is to confirm that the machines are doing what they are supposed to be doing.

Step 3: Safety System Design and Verification – Evaluate the risks and select control measures for the machine. For instance, if the overall system stopping performance is greater than the access time, a prevention device such as an interlocking guard with guard locking can be added. When applied, opening of the guard shall be prevented unless all hazardous functions covered by the guard have stopped. The goal is to protect both the process and to protect people.

Step 4: Safety System Installation and Validation – Document all stages, design a validation plan, test the installation safety functions and record the results and issue documentation.

Step 5: Maintain and Improve Safety System – A study by the HSE found that more than 50% of all accidents occur during maintenance and machine modification, so the safety cycle process must be used during machine upgrades.

safety-process

The 5-Step Process to Safety provides a framework for identifying potential machine operating risks and mitigating the occurrence of safety issues through preventative measures or other actions. The process is continuous as risk findings must be regularly reviewed. Once an action is taken to remedy an identified risk, that action must be monitored to confirm the potential risk remains at an acceptable level and no other issues have crept into the process that may have raised the risk level.
