Sure-Foot Prevents Slip and Falls

Anderson-Bolds and Sure-Foot Slip and Fall Prevention

SURE-FOOT Mats and Stair Treads and Tape

How Anti Slip Tape Keeps Workers Safe in the Oil & Gas Industry

Oil and gas is one of the fastest growing labor sectors, and with growth comes more liability.
2017 report showed the oil and gas industry has one of the highest rates of severe injury. With the sector’s constant growth, these injuries will continue to plague workers and cause slowed production, excess time off, long-term disability or even death.
You cannot eliminate the uncertainty surrounding labor-intensive jobs like those in the oil and gas industry but knowing about environmental hazards can help mitigate some of the dangers that lead to critical error and injury.
Sure-Foot Stair Treads

Sure-Foot Anti-Slip Tape
Slips, Trips, and Falls
Like so many other industries, prominent workplace hazard in the oil and gas industry lead to a slip, trip, or fall.
According to Occupational Safety and Health Administration (OHSA), most general industry accidents happen due to slips, trips, and falls. They also cause 15% of accidental workplace fatalities, second only to motor vehicles.
Slips, trips, and falls don’t just impact the worker, but they constitute a considerable amount of workers’ compensation and medical bills, over $70 billion yearly in the U.S., according to the National Safety Council.
Environments vary, but whether a workplace is involved in discovering, producing, obtaining, refining or distributing oil or gas, the ground can become slick from various liquids.
The combination of oil and water on steel surfaces can be a recipe for disaster for workers hustling through high traffic areas.
While metal products in these types of environments are often covered in slip resistant coatings, these coatings can quickly wear away in a short time when exposed to the harsh conditions of the oil and gas industry like offshore fracking sites.
Another issue that must be considered in these environments is exposure to diverse elements that can cause metal platforms to both rust and corrode. Things like salt water will only further the chance of equipment breakdowns and workplace injury.
Companies should invest in a well-planned strategy for workplace safety to combat these continuously dangerous situations.
Products like Sure-Foot’s anti-slip tapes are an excellent addition to surfaces that see heavy traffic or areas that are prone to accumulating moisture. For environments with extreme heat, cold, ocean exposure, increased foot traffic or other more strenuous factors, Master Stop EXTREME Tapes offers added adhesion and anti-slip safety.
Sure-Foot is also known for its fiberglass products, including step covers and walkway applications as well as product customization. Sure-Foot creates products that fit specifications for each customer, helping to increase and promote safety.

Vehicle Accidents

Accidents and incidents involving work vehicles continue to be a significant portion of workplace injury in the oil and gas industry.
For example, a vehicle could be driven to pipelines or pumping stations. Others could transport oil and gas. In addition, workers could be struck by work vehicles or machinery.
Many of these incidents can be attributed to carelessness due to employee fatigue. Long shifts, physically challenging work, and overexertion can lead to reduced awareness of workers.
Having safety signs, protective barriers and the proper warning labels on machinery can help to minimize these incidents. Adequate training for employees working with this equipment will make them more aware of the dangers they encounter in the workplace.
Injuries in the oil and gas industry will never be entirely preventable. But they can be limited with the proper safety planning, procedures, and safety products. Buy Sure-Foot to be sure!

SSAC/Littelfuse Voltage Monitor HLMUDLAAA

Voltage Monitor Protection Relay HLMUDLAAA from Anderson-Bolds
Made by Littelfuse

Contact Anderson-Bolds

LittelFuse SSAC Voltage Monitor HLMUDLAAA is a universal voltage monitor. 10 amp output relay rating. The HLM Voltage Monitor senses over or under voltage AND phase unbalance and frequency fluctuations and trips if any go oout of range. The Voltage Monitors are currently made by Little Fuse. UL, CSA and CE. Previous manufacturers were SSAC, Entrelac, ABB and Sycom.


The HLMU Series is a universal voltage, encapsulated, 3-phase voltage monitor. It continuously measures the voltage of each of the three phases with microcontroller accuracy and compares the value to preset trip points. It separately senses phase reversal and loss; over, under and unbalanced voltages; and
over or under frequency. Protection is assured during periods of large average voltage fluctuations, or when regenerated voltages are present. The unit trips within 200ms when phase loss is detected. Adjustable time delays are included to prevent nuisance tripping and short cycling of sensitive equipment. The isolated, 10A, DPDT relay contacts trip when a phase voltage exceeds the trip limits for the trip delay. Nominal line voltage, voltage unbalance, and time delays are knob adjustable. The phase loss setpoint and the acceptable frequency range are fixed. Both delta and wye systems can be monitored; no connection to neutral is required.

Voltage Monitor HLMUDLAAA

Constant monitoring to protect against phase loss, phase reversal; over, under, and unbalanced voltage; over and under frequency
Flexibility to work in 200 to 480VAC applications
Installation flexibility
Provides diagnostics of relay, fault and time delay status
Protects against shock, vibration, and humidity Meets IEC 61000 safety requirements

Upon application of line voltage, the output is de-energized
and the restart delay begins. If all the three-phase voltages are within the acceptable range, the output energizes at the end
of the restart delay. The microcontroller circuitry automatically senses the voltage range, and selects the correct operating frequency (50 or 60Hz). The over and under voltage trip points are set at ± 10% of the adjusted line voltage. When the measured value of any phase voltage exceeds the acceptable range limits (lower or upper) the trip delay begins. At the end of the trip delay the output relay de-energizes. If the phase voltage returns to an acceptable value before the trip delay expires, the trip delay is reset and the output remains energized. Under, over, and unbalanced voltages plus over or under frequency must be sensed for the complete trip delay before the unit trips. The unit trips in 200ms when phase loss or reversal are sensed. The unit will not energize if a fault is sensed as the line voltage is applied. 

Reset: Reset is automatic upon correction of the voltage or frequency fault or phase sequence.

Restart Delay Options
L = Lockout or minimum OFF time. The restart delay begins when the output trips. The unit cannot be re-energized until the restart delay is complete. This provides a minimum off time
or lockout time to allow equipment sensitive to short cycling, time to reset. If the fault is corrected after the restart delay is complete, the output energizes immediately. The restart delay also occurs when line voltage is applied/reapplied.
R = Restart Delay on fault correction. The restart delay begins when line voltage is reapplied or when a voltage fault is corrected. This option is normally selected when staggered restarting of multiple motors on a power system is required.
N = No Restart Delay. 0.6 second initialization delay on application of line voltage applies.
Restart Notes: All restart options remain reset when the following conditions are detected:
1. Phase loss (phase unbalance greater than 25%) 2. Average line voltage less than 120VAC
3. Phase reversal

The restart delay begins when the condition is corrected.

LED Operation
The LED flashes green during the restart delay, then glows green when the output energizes. It flashes red during the trip delay then glows red when the output de-energizes. It flashes red/green if phase reversal is sensed. If a fault is sensed during the restart delay, the LED will glow red during that portion or the full restart delay.
