HUMAN EQUIPMENT INTERACTION
To comply with this High-Risk Operation standard, this specific document must be properly filled out, up to date, and actively followed
What is the HEI Planning Tool?
To ensure compliance with OSHA and to minimize risk, this must be in place and understood by the crew before high-risk work begins.
What is a recuse plan?
To ensure a safe, heavy-duty procedure, the operation has completed this, and it is strictly being followed.
What is a lift plan?
Ensuring the crane has proper swing radius protection, its tires are off the ground, it is on firm level ground using correct cribbing, and is within manufacturer's tolerances all contribute to this essential operating condition.
What is a proper or safe setup?
Depth of ground penetration needed for dig permit
what is any penetration of the ground.
To avoid accidents, the crew has been reminded to get visual confirmation—specifically "bucket down and hands in the air"—before approaching this.
What is heavy equipment (or machinery)?
To prevent accidents, OSHA requires that this type of area be marked with signs and have measures in place to prevent unauthorized entry.
What is a (permit-required) confined space?
According Life Safety Categories, the procedure for removing rigging that is currently supporting or securing a load is addressed in this, which may include a "Red Bolt Program.
What is a Start Card?
Before lifting, the operator must ensure this document, which is specific to the machine's model, boom length, and counterweight, is used to determine safe capacity
What is the load chart?
The minimum clearance shall be maintained between and underground utility and the cutting edge or point of any power operated excavating or earth moving equipment.
What is the 3 foot rule
This safety reminder emphasizes that crew members must obtain visual confirmation— including a bucket down and hands in the air—before approaching any equipment operations.”
What is maintaining safe approach procedures?
To ensure safety in a Permit-Required Confined Space, OSHA requires that these three key team members be properly trained.
What are the Entry Supervisor, Entrants, and Attendants? (or "The Entry Team")
To avoid failure during a lift, a rigger must ensure this, the maximum weight that equipment is designed to handle, exceeds the load.
What is the Safe Working Load (or Working Load Limit/WLL)?
Required for high-risk, non-routine, or multi-crane picks, it’s the document that must be complete and accurate, ensuring the lift is safe to proceed.
What is a (Critical) Lift Plan?
What is 25 feet.
The maximum allowable lateral travel distance to a ladder, ramp, or stairway for employees working in a trench 4 feet or deeper.
Equipment operation and human foot traffic are PHYSICALLY separated (fencing, relocate operations, gates, etc.) with separate access routes for equipment and personnel.
What is physical separation of equipment and pedestrian traffic?
To manage crowd flow and security, this essential protocol ensures a clear, consistent dialogue between entrance staff and interior attendants.
What is an effective communication plan?
Whistles, air horns, and gongs are commonly used to provide this type of "audible" alert when overhead loads are in the air.
What is a warning signal? (or What are warning devices?)
To ensure worker safety during construction, overhead electrical conductors must be identified with signage, physically marked, insulated, or doing this to provide a safe, low-resistance path to the earth.
What is grounded (or grounding out)?
Employees are protected from falling rock and other debris while in a trench or excavation.
What is the Occupant Protection System (or Shielding)?
Any change of elevation and potential for rollover has been identified and addressed in the work plan.
What is identifying and addressing elevation changes and rollover risks in the work plan
To comply with OSHA regulations, this crucial pre-entry step involves using a bump-tested & calibrated device to check for oxygen, toxics, & combustibles.
What is air monitoring? (or What is gas detection/testing?)
To avoid injury, this person(s) understands the center of gravity and stays out of the "line of fire" from any potential load shifts
What is Rigger 1 / Rigger 2?
Craft possess the necessary training, experience, and skills to safely operate equipment, as determined by the employer.
What is the operators' qualifications?
Air has been tested in the trenches where the possibility of hazardous atmosphere exists.
What is air quality testing?
