ShoveIt® Tools

Prevention of Pinch-Point Injury

The ShoveIt® no touch hand safety tool manufactured by the Hand Safety Tool Company helps avoid hand injuries while working with suspended loads or manoeuvring objects, maintaining proper body positioning for safe handling out of the line of fire.

The Push Pull Tool allows users to guide loads, move and position pipes and tubulars, as well as grab slings and taglines without physically placing hands on the item.

The SnareIt™ no touch hand safety tool eliminates finger and hand exposure to the danger zone while safely manoeuvring pipe or other like cylindrical-shaped equipment. The hand tool makes it easy to quickly tighten or loosen the cable around the item to be maneuvered, mitigating risk by minimizing exposure to potential hazards.

The HookIt Tool acts as an extension of the worker’s body to move, push or reposition the item keeping hands and fingers out of the danger zone, avoiding crush and pinch points while at the same time sustaining control of the object being positioned.

While initially designed specifically for lifting grating, the HookIt can be used for a multitude of jobs including, as an extension to move, push or reposition items and equipment, as a rigid tagline to grab wire cables or slings and when used with the Magna-Grab magnetic tagline, closing engine cowling doors, retrieving product out of box making machines, or even for manoeuvring suspended equipment like valves as well as other items with flange holes or openings.

The GrabIt™ hand safety tool helps enable hands-off operations by firmly closing around a pipe or other like object, ensuring a solid grasp when working with suspended tubulars. The Quick Tool Holder enables easy storage of and access to Hand Safety Tool Company tools.

Safe-T-Stik is the ultimate hands-off magnetic load control and positioning safety tool for moving road plate, trench plate, poles, pipe, I-beams, shipping containers, valves, fittings and any other heavy steel objects or large parts being lifted or hoisted into or out of position. The Magna-Grab is a multi- purpose, hands-off magnetic tool. It can serve as a portable magnetic tag line and tether anchor point or may be used as a long-reach, magnetic-retrieval tool.

Thorne & Derrick’s mission is to provide tangible solutions to reduce the impact of potential hand and finger injuries in all industries where hazardous conditions exist. We truly envision a world where hand injuries are no longer the number one recordable incident.

Manual Handling Push & Pull Tool Developed By The HSE

Safety Tools | Prevent Hand Injury Using Pushing & Pull Tools

---

By

Gwyn Evans BA (Hons)

The HSE has developed a new tool to assist organisations in reducing risks from manual handling pushing and pulling activities.

The guidance, entitled ‘Risk assessment of pushing and pulling’ (RAPP) provides a simple method for evaluating the levels of risk associated to your activities. By following the guidance, you will be able to identify your high-risk activities and check the effectiveness of your control measures.

The tool covers two distinct types of operation:

1. Moving a load which is mounted on wheels
2. Moving loads without wheels which involves dragging/sliding, rolling, or churning (for example, manoeuvring a tilted barrel)

Each type of operation is then broken down further by the typical equipment which may be used, or the manual handling method applied for movement.

There are flow charts to follow for both types of operation; leading you through a number of factors which affect the risk of injury. These include:

• Weight
• Posture
• Grip
• Work pattern
• Travel distance
• Floor surface
• Obstacles

Each factor receives a score based the level of risk, highlighting which create the greatest risk e.g. certain tasks may require poor posture, or require a number of obstacles to be negotiated whilst moving from A to B.

You’ll also now have a cumulative risk score for the overall task.

When assessing a number of different push/pull activities within your organisation, the cumulative scores can be used to compare tasks against each other. This enables you to prioritise your focus on those which carry the highest risk scores.

The results should mean that you can evaluate the effectiveness of your control measures quantitatively, thus giving you a firm grounding on which to base your risk assessments and safe working practices.

Pushing & Pulling Loads – RAPP Tools

The HSE aims to reduce work-related death, injury and ill health.

Pushing and pulling of loads is a way to reduce or avoid manual lifting and carrying. Putting the load on a trolley and pushing it is one way of avoiding carrying.

So, when people push and pull instead of lifting and carrying, less effort is required, but there may still be a risk of musculoskeletal disorders (MSDs), which you need to assess and eliminate or reduce.

Although you may think that the Manual Handling Operations Regulations only apply to the lifting, lowering and carrying of loads, they also apply to pushing and pulling.

This ‘pushing and pulling’ guide should help you comply with the regulations and control the risks to your workers.

A risk assessment tool for pushing and pulling operations (the RAPP tool) is available:

• It is a simple tool designed to help assess the key risks in manual pushing and pulling operations involving whole body effort.
• It is similar to the MAC tool and uses colour-coding and numerical scoring, like the MAC.
• It will help identify high-risk pushing and pulling activities and help you evaluate the effectiveness of any risk-reduction measures.
• You can assess two types of pulling and pushing operations using the RAPP:
  • moving loads using wheeled equipment, such as hand trolleys, pump trucks, carts or wheelbarrows;
  • moving items without wheels, involving dragging/sliding, churning (pivoting and rolling) and rolling.
• For each type of assessment there is a flow chart, an assessment guide and a score sheet.

NOTE: Since the RAPP tool was launched, our experience, supported by further testing, has indicated that the tool is not sensitive to the level of risk in some tasks (or parts of tasks) involving moving loads with hand pallet trucks or similar, with small wheels.

In these tasks, small irregularities (including debris) and small gradients in the floor surfaces, which would otherwise be assessed as low risk (Good G/0) under the A-7 Floor surface and A-8 Obstacles along the route factors, can have a very significant effect on the manual forces required. In these situations, the RAPP will tend to underestimate the level of risk, although the need for high force should be identified from looking at worker posture in factor A-2 Posture.

Therefore, a full, site-specific, pushing and pulling risk assessment may be preferable when assessing tasks (or parts of tasks) in locations with varying floor and environmental conditions. This is particularly likely for tasks that occur outdoors or can be affected by the weather, such as deliveries or loading/unloading in yards. Worker involvement in the assessment process is important as they have valuable knowledge of the specific risks of the task, particularly, for example, drivers who are experienced in delivery operations.

HSE has produced a pushing and pulling risk assessment checklist and an example checklist to help with your full risk assessments – contact HSE for further information.

Surge Counters | Monitoring The Health Of Surge Arresters

Surge Counters are used to monitor the health of Surge Arresters and protect against potentially damaging events which could lead to deterioration and ultimate overload. It is important to also schedule regular checks of surge arresters including visual inspection and diagnostics to detect and prevent a costly medium voltage power outage.

Well-designed and tested, ABB surge arresters are maintenance-free and can reasonably be expected to have a long service life. However, the condition of these surge arresters should also be monitored to ensure the most ultimate protection against a costly unplanned power outage. This can be achieved using the ABB EXCOUNT range of surge counters and monitors.

Surge Counters

Surge registration

The primary reason for the use of surge counters on modern gapless ZnO arresters is to check if a particular transmission line or phase suffers from an exceptionally high number of overvoltages leading to arrester operation — lightning faults on a line, for example. If this is the case, whilst it validates the need for the arresters, use of some preventative counter measures may be warranted to limit the number of surges. A sudden increase in the counting rate may also indicate an internal arrester fault, in which case the arrester should be investigated further.

However, simple surge counters tell only part of the story, as they only register the number of surges according to their operating characteristic. The user therefore has no way of telling the magnitude of the surge and if it was significant, nor when it occurred and if it was coincident with a system event.

Leakage current measurement

Surge counters can be complimented with the substation facility to measure leakage currents (total and/ or resistive), with the intention of monitoring and diagnosing the condition of the arrester and its state of fitness for continued service. However it is important to understand the validity of the information provided.

At continuous operating voltage (Uc), a metaloxide varistor acts as a capacitor, leading to a predominantly capacitive component of current and a significantly smaller resistive part. For a complete surge arrester, the capacitive current is further dependent on stray capacitances, pollution currents on the insulator surface, number of varistor columns in parallel and the actual operating voltage. Meanwhile the small resistive component of the leakage current is temperature and voltage dependant.

Since the capacitive component of the current dominates so greatly, the total leakage current measured on a basic mA-meter will be very sensitive to the installation; making interpretation of the readings difficult. Furthermore, the capacitive current does not change significantly due to deterioration of the voltage-current characteristic of the surge arrester. Consequently, measurement of capacitive current cannot reliably indicate the condition of metal-oxide arresters. Nevertheless, increasing values may be of some use in indicating that cleaning of the insulators is necessary.

Instead, it is generally recognized (IEC 60099-5) that the only reliable indicator for the condition of a gapless arrester that can be assessed during normal service is to measure the resistive component of the leakage current (or estimate it from the 3rd harmonic).

The obtained value may then be compared with the maximum allowable resistive current as given by the manufacturer under prevailing service conditions i.e. temperature and applied voltage.

If a metal-oxide varistor ages or is damaged by impulses etc, the arrester resistive leakage current, and hence power losses, increase permanently. This may result in an increase in temperature, which in turn, increases the leakage current and so on until a so-called thermal runway occurs. Early detection of a possible harmful increase may prevent a failure and subsequent unplanned shutdown. Hence, to provide true diagnostics, a good monitor must be able to detect the arrester leakage current and isolate and measure the resistive component flowing internally.

Diagnostic plan

A surge arrester does not contain any moving parts or items that can break.

Consequently there is nothing to maintain, adjust, correct or repair, which is why there is normally no need to perform any form of periodical checking or monitoring. In general, a correctly chosen and installed arrester is maintenance free during its entire lifetime. A correctly chosen arrester in this context means that its electrical and mechanical characteristics are matched to actual service conditions.

Nonetheless, since external factors can place stresses on the arrester, potentially leading to its deterioration and ultimate overload, it may be prudent to draw up a schedule for regular checks. Such consideration is all the more important if an unplanned outage is unacceptable for reasons of system stability or economics. The older the arrester, the more regular these checks may need to be, since the statistical risk for overload increases with age.

As a guide, the following strategy is proposed to be made at regular intervals as required and determined by site availability and importance:

• Visual inspection and possible cleaning
• Diagnostics in advance of the designated lighting season and thereafter following periods with bad weather conditions.
• Diagnostics after special fault conditions causing flashover in the network or TOV’s of high amplitude and/ or long duration.

Because of their nature, old-style gapped arresters should be removed as soon as possible as part of a scheduled replacement program. Their age and inherent design does not warrant detailed evaluation. Early models of gapless arresters may require additional visual checks to look for signs of mechanical or physical deterioration as well as monitoring of the internals. Newly purchased arresters can also benefit from diagnostic monitoring right from first installation since this permits easy trend analysis to detect potential deterioration later on in its service life.

Safety Comes First

Monitoring Surge Arresters

EXCOUNT draws upon over 80 years of experience by ABB in the development of arresters and associated accessories. Safety, functionality and longevity are key elements which are given priority in selection and design of components. The EXCOUNT range has not neglected short-circuit safety which lies inherent in the design concept.

The EXCOUNT family is characterized by:

Highest Personnel Safety

• Same electrical safety performance as ABB arresters

Negligible Residual Voltage

• Does not reduce protection margins
• Minimized risk for injury in case of accidental contact during surges

Maintenance Free

• Sealed components
• Requires no external power supply (except for EXCOUNT-III)

Long Life

• Moulded components, non-sensitive to humidity or temperature variations

Universal Application

• All makes and types of gapless surge arresters.
• All weather and temperature conditions.

Design

The use of an impulse current transformer with a single-turn primary ensures that the voltage drop across the counter is negligible, even at the highest impulse currents encountered in service. This leads to added personnel safety and no increase in the protection level of the arrester. Since no gaps or series impedance are used, there is no risk of internal arcing and consequent explosive failure in the event of a short-circuit following an arrester failure.

One further common feature with the entire EXCOUNT family is that all internal components are fully encapsulated in polymer. This provides sealing to IP67, which ensures no harmful ingress of dust or moisture as well as providing personal safety through complete protection against contact with the internals.

EXCOUNT is available in different variants, depending on the user’s needs: simple, basic or extensive. Contact Thorne & Derrick for more information.
