Vehicle and Equipment Blind Spots

Vehicle and Equipment Blind SpotsHeavy trucks & equipment is used on many different kinds of work sites all around the world. This equipment is very effective for the job it was designed to do, but it can also be very hazardous. Proper work planning as well as operating equipment within its designed limits are important basic steps for safe operation.


Struck-by hazards – Heavy equipment is responsible for many injuries and fatalities in the workplace. Ground personnel are far too often struck by equipment when they are in the line of fire.

Property damage – When operators do not see vehicles, materials, objects, tools, buildings, etc. in their area of operation property damage occurs. This costs employers millions of dollars a year in losses.

Collisions – when vehicles and equipment get close the risk of an accidental collision increases exponentially. The closer the riskier. Blind spots, complacency, and congested work areas are the leading causes of jobsite collisions.

Miscommunication – not having a well-defined and well understood plan is by far the most common hazard resulting in accidents. Take the time to walk down the job, route, and directions to get everyone on the same page BEFORE starting.

Best Practices:

  • All vehicles & equipment should be inspected and readied prior to use. Adjust the seats, mirrors, clean windows and check radios as part of the daily inspection process. Any problems found with equipment should be corrected before it is used. Document all defects on the daily inspection log.
  • A defined route and clear visual path for the operator when moving equipment from the point of origin to the work site. Stop look and listen before you take off or make a move. Take that extra second to look to your left, right and rear before moving that equipment or truck.
  • Operators should complete a walk around of their equipment every time before getting back into the cab to be sure no objects, people, or vehicles are in a blind spot. Someone might have just moved an item into the area a few minutes ago.
  • Establish a danger zone, that is; the working area where contact could result in personal injury or damage during operations.
  • Maintain a clear line of site between the operator and workers. Blind spots are common. If you can’t see the operator, they can’t see you. Always try to walk on the driver side of equipment as the passenger side has a larger blind spot.
  • Workers should keep a safe distance from all sides of the heavy equipment while it is in use. Be aware of the swing radius on certain equipment and, if possible, cordon off the area with barriers or caution tape.
  • Work areas should be properly delineated and enough space given to heavy equipment to operate properly. Clear out all unnecessary personnel, objects, and vehicles from where the equipment is operating. Keep light trucks back from the active work scene.
  • Operators should complete a walk around of their equipment every time before getting back into the cab to be sure no objects, people, or vehicles are in a blind spot.
  • Pull over to the side out of the way if you get confused, need directions or have to make or take a phone call. Loss of attention while you get things sorted puts you and others at risk as they maneuver around you.

20 Feet or 2 Eyes:

Fiore & Sons practice calls for us to keep 20 feet between all heavy equipment and trucks while on site or use 2 eyes of a spotter to help get in close to execute the work. Never drive up under the blind spot and turning radius of a pieces of heavy equipment like a scraper, excavator or crane. Use the “20 feet or 2 eyes” rule every day.

Speak up when others are in your blind spot; Listen up to avoid an injury or accident.

Injury Fall from Trench Box Ladder

Injury Fall from Trench Box LadderDESCRIPTION

While installing mainline piping for residential development in Castle Pines, CO an employee fell onto bedding while descending a ladder into a trench box. The ladder was extended above the box 8 feet and not secured at the bottom; being only hooked over the trench box ladder hook on the left side facing the run. As he mounted the ladder on the trench side it pivoted, he lost his balance and fell into the trench. Fortunately, the injured person was not seriously hurt being able to complete the day’s work afterward.

Overnight he was sore requesting and received medical treatment the following day, given two doses of prescription pain medication by the physician. Due to an oversight, he was not D&A tested although per policy he was required to do so. The Foreman and Laborer were both given disciplinary warnings. The laborer stated he had a close call earlier with the ladder pivoting due to not being secured, but failed to act on it. This is an OSHA Recordable Injury Incident.


Procedure or Practice not Fully Developed: During the investigation it was determined that a Safe Work Practice (SWP) did not exist for the routine task of assembling and using the trench box and access. A SWP is needed so all persons understand what is expected of them to work safely.

Incomplete Training/Communication: Failure to Utilize STOP Work, See Something Say Something (SSSS) or Speak-Up Listen-Up (SULU) practices by the craftsman and his co-worker present to secure the ladder after having a close call earlier in the day. Trench ladder use is considered routine and was not addressed in the Daily Toolbox. Toolbox talks are to capture routine tasks as well as new ones.

>Look into alternate ladder attachments, ladder types, and available equipment for double stack trench box applications.Incomplete or Inadequate Inspection: The Trench and Excavation Inspection form was competed but not thoroughly. The section addressing on safe access was not adequately looked at for ladder securement, and a clear access transition onto/off of ladder adjacent to the trench box.


> Prepare a (1) Safety Alert and (2) Safe Work Practice to share with work crews via Tailgate Topics and onsite Awareness. Discuss implementing SWP at next Foreman’s Meeting. Require all ladders to be secured with a safe access landing.

> The fall was significant and should have resulted in immediate notification to supervision and the employee being evaluated by a doctor. The D&A policy requires testing when employees are seen by doctor. Review policy with employees, Foreman and Supts.

> Update the FSI Trench & Excavation Form to add detail to the access and trench box set up portion. Have ready for next Foreman’s Meeting.

> Supervisors and HSE staff to document review of T&E Inspection form and all ladder usage as part of the Routine Safety Site Safety Inspection.

> Look into alternate ladder attachments, ladder types, and available equipment for double stack trench box applications.

Tips for Clear Communication with Two Way Radios

Radios are placed in company vehicles and equipment as a means of efficient & safe communications. They are not toys, a place for standup comedy routine or to discuss your weekend plans.

Think before you speak.

  • Decide what you are going say and to whom it is meant for.
  • Make your conversations as concise, precise, and clear as possible.
  • Avoid long and complicated sentences. Use brief messages.
  • Your voice should be clear. Speak a little slower than normal. Speak in a normal tone.
  • Do not use abbreviations or slang unless they are well understood by your group

Be Prepared: When you have the talk button pressed, no one else in your group can speak or be heard. Two way radios are a one-at-a-time system unlike telephones where you can interrupt and talk over each other. Think about your message beforehand. Think before you speak is always good advice.

Identify Yourself and Who the Message is for: Onsite all share the same radio channel. Use good manners to identify yourself immediately when you start transmitting. Get the attention of the person you want before relaying your message. “OVER” is used to let the other person know you’ve finished speaking.

Examples: “Corn Dog, this is Trash, OVER, dump the cut near me” or “Jake this is Sparky OVER, can you join me here at the pit?

Be patient: The other person may not be able to respond immediately; give them time to reply before re-sending your call.

Use short, clear and concise messages: As two way radios only allow one person to speak at a time, it’s best to keep your transmissions short, clear and to the point. This gives other users an opportunity to acknowledge your message or request further clarification before you carry on with your next point.

Radio users often repeat a message utilizing three way communication to make it clear that they’ve heard and understood the information.

Three-Way Comms: Sender says his message, receiver repeats it back, sender agrees or provides more detail. Always keep messages short.

Pause before speaking: When you first press the push to talk (PTT) button, there can be a short delay before your radio transmits. This could result in your first couple of words being cut off, so wait a second or two before speaking to be sure your listeners receive your whole message.

Learn the lingo: It helps two way radio communication when everyone understands and uses similar language and etiquette, especially when there are more than two people using the channel.

  • Over – I’ve finished speaking
  • Say Again – Repeat your last message
  • Stand-by – I got it, but can’t talk right now
  • Go ahead – I can respond, go ahead with your message
  • Roger – message received and understood
  • Affirmative / Negative – Yes / No
  • Out – Conversation is finished

The phonetic alphabet: It’s often necessary to clarify an important part of your message by spelling it out. Following is a list showing the phonetics used for the alphabet:


Use your radio professionally. If not, your handset will be removed and you will have to follow instead of lead.

Fire Extinguisher Use and Inspection

Fire extinguishers are an important tool in preventing a small fire from growing larger. However, they should not be used to combat large or rapidly spreading fires. The most important thing to do during a fire is to get yourself and coworkers to safety then call the proper authorities (911) to combat the fire. Equipment, building, and property are not worth putting yourself or anyone at risk trying to put it out with a fire extinguisher. It is important to understand how to use a fire extinguisher and the limitations they have. Most only spray for 10 to 30 secs after that you are left beating out the fire with a red cylinder on the end of a hose!

Fire extinguishers are only designed to fight small firesP.A.S.S. Method

The easiest way to remember how to use a fire extinguisher is to follow the P.A.S.S. method. The PASS acronym was developed to allow people to remember the basic four steps to properly use a fire extinguisher.

P- Pull. Pull the pin. Hold the extinguisher away and release the locking mechanism.

A- Aim. Aim the stream towards the base of the fire. Spraying the flames will not put the fire out.

S- Squeeze. Squeeze the lever slowly and evenly. Pulling the lever too fast may shoot the stream from your target wasting the valuable firefighting agent.

S- Sweep. Sweep the nozzle side to side to combat the fire.

Fire Extinguisher Limitations

  • A dry chemical fire extinguisher (“ABC”) will reach a distance between 5 and 20 feet. It is important to be familiar with the models used in your work areas.
  • A 10lb to 20lb dry chemical fire extinguisher will last anywhere from 10 to 30 seconds.
  • Fire extinguishers are only designed to fight small fires. A rule of thumb is the size of the fire should not be any larger than the size of a small trash can.

  • Extinguishers in office, yard and onsite should be checked each month. Extinguishers on equipment should be checked every day with the Daily Inspection. These inspections should be documented and turned in. A formal check by a third party of all fire extinguishers is done annually and a decal applied to the body.
  • Ensure the pressure is okay when inspecting a fire extinguisher. There is a gauge that has an arrow that should be in the green portion of the gauge. If the arrow is in the red the fire extinguisher needs to be tagged out of service until recharged.
  • Check to make sure the pin is still in place. Often times the pin is bumped out of place leaving the chance of accidental discharge occurring.
  • Look for rust on the container and ensure that the label is in good readable condition. Verify that the latch or strap holds the unit in place.
  • Look for mud, insects, and debris in the hose end of the extinguisher to make sure it is not plugged. Check to see if the hose is cracked or damaged.
  • Make sure there is a tag on the extinguisher and it is signed off each month. Operators/drivers sign off on their equipment extinguishers.
  • Turn in used or inoperative extinguisher to warehouse or your supervisor to be serviced or a replacement one put in its place.


It is important to know more than just where the fire extinguishers are located in your work area. Make sure you know how to properly use them in case the time comes where you need to extinguish a fire. Always make sure the fire extinguishers in your work areas are in good condition through thorough inspections. If you are unsure on extinguisher operation ask your supervisor for help & demonstration.

All equipment, trucks, pumps, gensets, mechanics, oilers, offices & welding areas are to have a fire extinguisher.
