Applications

When set up properly the PX3 allows for three workers to be tied off for fall arrest using the specially designed fall arrest connection mechanism. An additional two workers can be tied-off for fall restraint at the specified attachment points.
Fall restraint is a proactive measure designed to prevent falls from occurring in the first place. It involves implementing preventive measures through components such as body harnesses attached to anchorage, connectors, and other necessary equipment. The primary objective is to restrict a worker’s movement and prevent them from reaching a position where a fall hazard exists. The PX3 can be used as an anchorage in a fall restraint system for up to two workers.
Fall Arrest can be used when fall restraint is not ideal or not an option. It involves utilizing equipment and systems that can effectively arrest the fall and minimize the potential injury or damage. Fall arrest systems typically consist of anchors, anchorage points, connectors, and personal protective equipment (PPE) such as harnesses and lanyards. These components work together to ensure the worker’s safety by stopping their fall and preventing them from striking lower levels or encountering other hazards. The PX3 can be used as an anchorage in a personal Fall Arrest System (PFAS) for up to three workers.
A fall arrest system must meet the following OSHA requirements:

• 1910.140(d)(1)(i)Limit the maximum arresting force on the employee to 1,800 pounds (8 kN)
• 1910.140(d)(1)(ii) Bring the employee to a complete stop and limit the maximum deceleration distance the employee travels to 3.5 feet (1.1 m);
• 1910.140(d)(1)(iii)Have sufficient strength to withstand twice the potential impact energy of the employee free falling a distance of 6 feet (1.8 m), or the free fall distance permitted by the system

Anchorage — Anchorage means a secure point of attachment for equipment such as lifelines, lanyards, or deceleration devices. PX3 is an engineered mobile anchorage device.
PX3 Use – Flat surfaces to slopes up to 1:12.

Before Using the PX3

OSHA requires that before operating the system there must be an inspection for damaged equipment.

1. Check for loose, bent or damaged parts, including the five penetrating spikes.
2. Check welded components for distortion, cracks, or other damage.
3. Check Tie-off shackles for distortion or damage and confirm that they are properly tightened.
4. Check retaining slide bars for rusting and/or wear before each use. All labels must be present and fully legible. (Copies of all labels are attached at the back of this section for accurate inspection.)
5. Check for all pull pins that they are fully inserted and the safety cotter pin clips are attached to each pull pin.

Maintenance and Care

• Inspect PX3 before and after each use.
• Keep wheels free from roofing debris
• Regularly inspect for damaged or missing parts and do not place the PX3 into service until all missing and or damaged parts have been replaced.
• Store the PX3 in a place protected from weather and where only authorized employees have access.

Procedure for Handling the PX3 After a Fall

Before rescuing a fallen employee….
It is recommended to call 911 before making rescue attempt
Any rescuer must be tied off in a Fall Restraint System (FRS) before attempting to aid in a rescue. The number of rescuers allowed to tie off to the PX3 is 3 minus the number of fallen workers. Up to 2 (two) additional rescuers may tie off to the PX3 utilizing the two fall restraint tie-off shackles marked for FRS.
To use the Tie Down Rescue System for the PX3, you will need to also have a rescue pole accessible to properly reach the back dorsal D-ring of the worker who is being rescued. DO NOT ATTEMPT TO RESCUE THE WORKER UNLESS YOU ARE PROPERLY TIED OFF TO AN APPROPRIATE ANCHORAGE CONNECTION. ATTEMPTING TO RESCUE A WORKER WHEN NOT BEING PROPERLY CONNECTED TO AN APPROVE ANCHORAGE CONNECTION CAN RESULT IN SERIOUS INJURY INCLUDING DEATH.
Workers must be properly trained in the use of the Tie Down Rescue System PRIOR to use. Do not use the Tie Down Rescue System unless you are trained by a competent person and that training must be documented to have been conducted prior to use. Failure to properly train on the safe use of the Tie Down Rescue System could result in serious injury including death.

Evaluate the situation
The event that led to the fall may create additional risk that need to be addressed. Determine weather the fallen worker is to lifted back to the roof top or lowered to the ground.

If the Worker is Conscious
Release the cable from the winch and lower it to the fallen worker. Have the fallen worker hook the cable to his harness.
If the cable length and ground conditions allow, it is recommended to lower the worker safely to the ground. If the ground environment is not safe or the cable length is not long enough, then raise the fallen worker to the roof top.

Procedure for Handling the PX3 After a Fall

If the Worker is Unconscious
If the fallen worker is unconscious or unable to hook themselves up to the rescue cable additional rescue help will be needed. The additional worker must be tied off to the PX3. Using a rescue pole attach the hook/ cable to the fallen worker.
If the cable length and ground conditions allow, it is recommended to lower the worker safely to the ground. If the ground environment is not save or the cable length is not long enough, then raise the fallen worker to the roof top.
Treat the worker for suspension trauma and any other injuries.
Arrange for transportation to the nearest hospital.

Procedure for Reseting the PX3 After a Fall
Prior to disengaging the PX3 after deployment as the result of a fall incident, make certain that the rescue procedure has been successfully completed.
The five penetrating spikes will be somewhat buried into the roof after activation.

Follow these steps to reset the PX3 Device:

1. Loosen the large wing nuts on both sides of the PX3 device.
2. Attach the pull hooks to the top loop of the retaining slide bar. Repeat for opposite side.
3. With a firm pull, pull the handle outward away from the PX3 cart. The Spike assembly will slide back to it’s original position.

Placement/Positioning of the PX3 Cart

Prior to Positioning the PX3: Verify that the surface is capable of supporting the Penetrator X3, and all personnel using it.
During Repositioning the PX3: Active fall restraint is maintained by a maximum length of five feet less than the distance of the cart to the leading edge. The attachment tie-off anchor points must be pointed toward the leading edge and the cart is set to travel parallel to the unprotected edge or leading edge. Position the PX3 such that the front guard plate is minimum of 8 feet from the leading edge, and in line with the center of the area to be worked.

IMPORTANT: When repositioning the PX3, active fall restraint is maintained by a maximum length of five feet less than the distance of the cart to the leading edge. Once repositioned, place and re-pin retractable handles back in resting position.

Range of Use

Range of Use is double the distance from the leading edge up to 15 feet.

After 15 feet the maximum Range of Use is 30 feet.

Connecting to the PX3
DO NOT hook Personal Fall Arrest System (PFAS) to any point except a Fall Arrest or Fall Restraint Tie-off Anchor Point.
When making connections, only use double-locking snap hooks and double-locking carabiners with this equipment. Only use connectors that are suitable to each application. Ensure all connections are compatible in size, shape and strength. Do not use equipment that is not compatible.
Ensure that all connectors are fully closed and locked.

The Fall Restraint Tie-Off
Two Fall Restraint Anchor tie off’s are located on the top corners of the PX3 where labeled. The Fall Restraint tie off’s DO NOT arrest falls. The user must ensure that the Fall Restraint worker is personally equipped with lanyards, harnesses, safety lines, etc., when working in conjunction with potential fall arrest workers.
Do not attached fall restraints to the hoisting ring locations.
Do Not allow the fall restraint users to work close to any roof edge.
FALL ARREST TIE-OFF
The three Fall Arrest Tie Off points are located on the lower side of the PX3 in bright red, under of the stay clear guard. The user must ensure that the leading edge connectors and harness are properly attached.
IMPORTANT: DO NOT allow workers to cross paths (cross lines) at anytime! Fall Restraint/Fall Arrest lines must never cross over each other. Crossed lines will cause the unit to not function as intended. Failure to maintain clear lines may cause a accident or death.
