- 4. Dropped Object Awareness UnderstandingDropped Objects • What is a Dropped Object? Any object / item that falls from its previous position (TOOLS, EQUIPMENT, STRUCTURE, LOOSE ITEMS, LIFTED OR TRANSPORTED LOADS, STACKED / STORED MATERIALS…). REMEMBER: GRAVITY IS A WORKSITE HAZARD!
- 5. Dropped Object Awareness DroppedObject Categories • Static Dropped Object any object that falls from its previous position under its own weight – where Gravity takes over! • Dynamic Dropped Object any object that falls from its previous position due to applied force from equipment/machinery or moving object – like a collision, perhaps during lifting or stacking… also manual handling, pressure or electrical energy sources too Now think about objects that can fall due to failure caused by repeated cyclic loading, environmental factors and movement – vibration, temperature, wind and so on…

- 26. Dropped Object Awareness TOOLSAND EQUIPMENT AT HEIGHT All parts, equipment and materials that are worked with at height shall be secured against being dropped. Smaller parts shall be stored in suitable storage boxes, bags, etc. In restricted areas, such as the derrick, man- lifts and cranes, tools used at height shall be logged out and in to ensure that nothing is left behind.
- 27. Dropped Object Awareness TOOLSAND EQUIPMENT AT HEIGHT All temporary tools and equipment taken aloft must be recorded in the register. When the work is finished, a final check and inventory count shall be carried out to ensure that no tools, equipment or materials are left behind at height.
- 28.
- 29. Dropped Object Awareness RELIABLESECURING Reliable Securing provides a safeguard against potential yielding, displacement or failure of fastenings which can lead to equipment or structure falling. It also reduces the consequences of dropped objects through implementation of appropriate safety securing systems.
- 30. Dropped Object Awareness RELIABLESECURING PRINCIPLES: PRIMARY FIXINGS Confirm Primary Fixing method (ie clamping, bolting, pin, turnbuckle etc) is appropriate and as per OEM recommendations. Consider materials, tensions, tolerances as per Bill of Materials. Consider the effect of vibration or other dynamic forces that could cause disengagement.
- 31. Dropped Object Awareness RELIABLESECURING PRINCIPLES: SECONDARY RETENTION Confirm Secondary Retention device (ie lock washer, tab washer, lock nut, cotter pin, lock wire etc) is installed correctly as per OEM recommendations. Consider how these devices lock in the tension on a bolted connection, prevent movement or reduce the effects of vibration. There are primary fixing methods (such as some beam clamp designs that do not feature any secondary retention.
- 32. Dropped Object Awareness RELIABLESECURING PRINCIPLES: SAFETY SECURING Confirm Safety Securing nets or wires are rated, correctly secured to the structure and in good condition. Ensure these are replaced if removed for maintenance or if they are subjected to any loading.

- 36. Dropped Object Awareness DROPSVISUAL INSPECTIONS Annual DROPS Surveys and Systematic Inspections are performed to ensure all items are secured in areas where there is significant potential for personnel injury or asset damage if a dropped object event was to occur. Pretask inspections of all equipment, tools and worksites are performed to ensure all items and components are secured to prevent dropped objects.
- 37.
- 38.
- 39. Dropped Object Awareness REDZONE MANAGEMENT Restricted Access Zone: Medium potential risk – restricted access zone is an area in which a dropped object potential has been recognized. No-Go Areas / No Entry Zone: High potential risk – no go areas / no entry zones is an area in which dropped object potential has been recognized.
- 40. Dropped Object Awareness REDZONE MANAGEMENT Routine Operations: Drilling, Tripping (RIH, POOH, Drifting, Making Up) Non-Routine Operations: Derrick Maintenance and Inspection, Tubular Pick Up and Laydown, Jarring, Wireline, tool and tubular transfers with crane, slick line operations…
- 41. Dropped Object Awareness KEYCONSIDERATIONS? (If working in the Red Zone) Every task, even mundane activities require a plan; All operations will be conducted under PTW; Only persons required for the task may enter; Minimise exposure, identify step back areas when machinery is moving; Be aware of all other hazards; No personnel may join a task without a Tool Box Talk; Follow Red Zone Marshall’s instructions at all times.
- 42. Dropped Object Awareness UnderstandEach General Requirement? TASK PLANNING AND RISK ASSESSMENT • All repairs and maintenance work carried out at height shall be risk assessed. TOOLS AND EQUIPMENT AT HEIGHT • All equipment used where there is a risk of the equipment falling to an underlying level shall be secured against being dropped. • Smaller parts shall be stored in suitable storage boxes, bags, etc. • In restricted areas, such as the derrick, man-lifts and cranes, tools used at height shall be logged out and in to ensure that nothing is left behind. • When the work is finished, a final check and inventory count shall be carried out to ensure that no tools, equipment or materials are left behind at height.

Editor's Notes
- #1 Welcome. Safety Briefing, Comfort etc. Ensure you have handouts prepared – DROPS Calculator as a minimum, ideally copies of DROPS Reliable Securing. Also include any of your own Hazard Identification and Task Risk Assessment Tools. Ensure you have a copy of your Company Drops Procedure for reference. This presentation has been produced on behalf of your worksite with the full support of DROPS – The global industry initiative focused on eliminating dropped objects from the workplace. It is in 2 parts. In this first part we Introduce DROPS and our commitment to dropped object prevention through our procedures and actions. We will discuss the definitions to ensure we truly understand the Hazard and respect how severe the consequences can be. We will look at the common causes and share learnings from some of our incidents that have occurred on our rig. In the second part (this can be after a short break, or follow up on another day) we will explore the controls that we have on site that, with your full involvement and vigilance will ensure we make every effort to prevent dropped objects at source and enforce the mitigations that eliminate the risk of exposure to personnel.
- #2 Introduce concept of DROPS (the global initiative, we are all are active members – sharing best practice and striving for second nature dropped object prevention strategy). Specifically, review and confirm all obligations with regard to Company Drops (Dropped Object Prevention System). Be sure to address any client specific standards (for example KPO have standards and requirements with regard to dropped object management). State that the requirements reflect industry best practice – and that the foundation for DROPS came from systems that are employed in many other industries (such as defence and aerospace). DROPS applies to all tasks and is a key element of our HSE management system. Summarise that DROPS, the global initiative continues to grow in membership and knowledge which is shared freely and continually enhanced with new techniques and technologies. >>
- #3 Introduce your corporate procedure, noting that the requirements and practices presented are all based on the foundation of DROPS and refer to DROPS Guidance materials such as Reliable Securing. Note that the content of Reliable Securing includes advanced guidance on fastenings to support equipment inspections, but also contains a number of useful job aids and prompts to support task risk assessment and planning.
- #4 First let’s make sure we understand what a dropped object is. Let us look now at how we define dropped objects and understand their causes and consequences. >>What is a Dropped Object? Ask the class. >>(Reveal answer) A dropped object is any item or object that falls from its previous position. In essence, a dropped object is the result of the uncontrolled release of gravity. Ask delegates to describe how each of the different kinds of items could become dropped objects.
- #5 It is important for us to analyse dropped objects and define them further – so we can understand how they happen and what we can do to prevent them. Ask delegates if they know what the two definitions of dropped objects are. Try to use a visual example – perhaps something in the worksite or classroom. You could even use a pen attached to a piece of string… >>Static - any object that falls from its previous static position under its own weight – the weight of the pen causes the knot in the string to fail and it falls. Gravity is one of the hazards identified in our Hazard Identification Wheel. >> Dynamic - any object that falls from its previous static position due to applied force from equipment/machinery or moving object – the pen is struck or is snagged, causing the knot to fail or the string to snap. Think Gravity, plus mechanical, motion, pressure – even electrical (electric shock from power tool results in drop etc) >> Also consider kinetic potential - any object that falls from its previous static position due to failure caused by repeated cyclic loading and movement – the pen swings continuously in a noisy, vibrating, windy environment – perhaps extreme temperature changes too - for days, weeks, months, causing the knot to fail or the string to snap or even the pen clip to fail due to the continuous wear. Consider more combinations of potential hazards that affect items secured or stored at height – or even stacked against a wall. If we add other factors such as corrosion or poorly selected and installed fittings, we begin to identify potential scenarios around common working activities that can cause dropped objects. Discuss some more examples / real incidents. Determine which were static, which were dynamic and which were kinetic. We will study these in more detail later on. >>
- #6 Discuss Static, Dynamic - and Kinetic. Use the Hazard Identification Tool. Can you identify any potential dropped objects? What about the canoe. How could it become a Static or Dynamic dropped object? When (ie which task) is it most likely to become a dropped object? Garage door motor – potential for this to fall? Perhaps during maintenance, or due to lack of maintenance. Consider planning (ie method, approach, selection of materials) Consider scenarios (ie working on the garage door motor, colliding with canoe, canoe falls) Consider controls (eliminate, substitute, control) Also discuss risk ranking – which items would be most likely to fall and what would be the consequence?
- #7 Insert your own examples
- #8 Note the unsecured items. How might they fall and what would be the consequence.
- #9 What do you see in the image?
- #10 How could these items become dropped objects?
- #11 Even relatively small incidents can lead to a significant incident… (insert movie ‘Butterfly’)
- #12 Invite the delegates to consider the main root causes of dropped objects. Note responses on white board. Recall some of the incidents quoted earlier by delegates and discuss relevant causes and factors. Explain that above all it’s Safety Culture that bears most influence on whether dropped objects (or any other undesired events) occur. Incidents and accidents WILL happen in the absence of a strong safety culture - one that makes us consider safety and the effects of our actions and omissions in ALL that we do. A poor safety culture or safety ethic will manifest itself in poor behaviours such as complacency, neglect and blindness to hazards and changes around us. But it is important to consider what leads a person to make mistakes. Error traps such as inadequate materials and tools or unclear instructions and procedures – even the working environment itself can be an error trap. Beyond behavioural and cultural causes, we can categorise more specific root causes for dropped objects as follows: >> Reveal main root causes and compare with delegate responses. Sum up noting that all causes relate to failings with People, Plant or Procedures – or a combination of all. Can you add any others? Of course we address housekeeping continuously, ensuring no loose or unsecured items are left at height. We conduct pretask checks and hazard hunts which include searching out loose items and removing them, or securing items that can become dynamic dropped objects. We conduct post task inspections to ensure no unnecessary items are left at the worksite. But our DROPS program is much broader, with systematic controls across all aspects of every task.
- #13 Ask the class – What are the consequences of dropped objects? >>Click to reveal: It’s a fact. Dropped Objects account for around 35% of all safety related incidents. Throughout our industry, over 60% or more of all High Potential incidents (including those where personnel were not actually exposed) are dropped object related. We must not forget that dropped objects account for a number of incidents that cause equipment and environmental damage, lost time and lost production and ultimately damage to the business.
- #14 Introduce the DROPS Calculator, the common benchmark for providing a cursory indication of a possible outcome. Note that it only reflects blunt force trauma and is not compatible with sharp objects. Sharp items such as sharp tools, sharp edged materials etc are likely to result in more severe injury such as puncturing of the skin. Use the Calculator to work out the potential consequences of each of the items. Discuss what you would do to prevent the item from falling unintentionally. Note that the discussion regarding use of a hammer at height should also consider how it is transported to and from the worksite and perhaps more importantly, what will be struck by the hammer and whether that item could be a dropped object. Insert your own examples and animations if required.
- #15 How do we actually know what the potential consequence would be if an item (tool, piece of structure or equipment, container, loose item) were to fall and strike someone? We do need to have a realistic idea of this if we are to complete the Written Risk Assessment. We need to know the Severity rating. Here is a real example of what would happen if this 220g hex bolt fell approx 27m and struck a person below, on the head – a person wearing a hard hat. Fall energy is calculated as (mass/kg x distance/m x gravitational acceleration @ 9.8066m/s2). Using this calculation, the bolt will achieve 58Joules of fall energy. Also note that gravitational acceleration is a constant force that cannot be isolated at the worksite! It only takes 45Joules to create enough impact force to fracture an unprotected human skull. Also note that it takes 95Joules of fall energy to generate enough force to crack a hard hat! Click to reveal similar examples (ie 0.8kg spanner dropped from 7m would also generate 58J, the hammer at 1.4kg only needs to fall 4.3m to generate that same). >>click to play next slide with video of impact on the water melon
- #16 Watch movie. Bolt is going to be dropped through the centre of a stand of tubulars. Discuss what happens. Note that the bolt does not pass through the hardhat. Force is transferred through the hat, cradle and into the head. Consider the effect on neck and back.
- #17 In determining where an item may drop, there are many factors to consider including the shape, size, weight, weather effects and potential for deflection. Suspended loads that fail and fall significant distances can drop within a ‘cone’. Where items drop from within or above other structures, including temporary structures or equipment (such as scaffolding or mobile working platforms) there is a real potential for deflection. >> The DROPS exclusion zone calculator provides a cursory indication of deflection trajectories. The calculator tool allows for the deflection point to be adjusted to show the differing paths an object may take. Both tools should be used in the Risk Assessment to inform potential severity and also determine appropriate barricading at the point in the task where the risk of dropped objects increases (ie when removing fastenings or using tools).
- #19 Summarise the first part by asking the class what they have learned. >>Reveal the list. >>Close with Questions and Answers Thank You. Looking forward to seeing you for the second part (schedule the second presentation e.g. after a short break or perhaps following day/week).
- #20 Welcome. Safety Briefing, Comfort etc. Ensure you have handouts prepared – DROPS Calculator as a minimum, ideally copies of DROPS Reliable Securing. Also include any of your own Hazard Identification and Task Risk Assessment Tools. Ensure you have a copy of your Company Drops Procedure for reference. This presentation has been produced on behalf of your worksite with the full support of DROPS – The global industry initiative focused on eliminating dropped objects from the workplace. It is in 2 parts. In this first part we Introduce DROPS and our commitment to dropped object prevention through our procedures and actions. We will discuss the definitions to ensure we truly understand the Hazard and respect how severe the consequences can be. We will look at the common causes and share learnings from some of our incidents that have occurred on our rig. In the second part (this can be after a short break, or follow up on anther day) we will explore the controls that we have on site that, with your full involvement and vigilance will ensure we make every effort to prevent dropped objects at source and enforce the mitigations that eliminate the risk of exposure to personnel.
- #21 Ask the class, what are the most effective controls when it comes to preventing a dropped object. Discuss each from the most effective to the least effective. >> Elimination of the item, or elimination of the dynamic force that could cause an item to drop. >> Substitution, replacing with less hazardous item (ie lighter or lower) or changing the item (ie remove metal signage and replace with stencil) >> Engineered Controls – the devices and fastenings that prevent the release of gravity (reliable securing) >> Isolating people by identifying the cone of exposure and creating barriered red zones and restricted access areas >> Administrative Controls such as inspection, verification, training, procedures, permits etc >> PPE – not very effective in protecting personnel from fall energy and impact.
- #22 Ask the candidates which Controls are available at the worksite to reduce the likelihood of dropped objects (respond to the threat and stop dropped objects) and which controls reduce the consequence (recovery controls or fail safe measures). Reveal the answers. Briefly summarise each item. You could discuss JSA of a familiar task, identify which dropped objects have been identified and which of these controls have been applied and how they are managed. We recommend focusing on the underlined items: Task Planning and Risk Assessment Tools and Equipment at Height Reliable Securing (primary fixings, secondary retention and safety securing) Survey and Inspection (including cargo handling) Red Zones
- #23 Choose your own task example. Emphasise the requirement to identify both static and dynamic potentials and determine appropriate control measures. Introduce the concept of the DROPS Calculator and how this can be used to familiarize personnel with the potential consequences. Take the time to consider which tools and equipment are being used, how collisions may occur, how the weather or working environment can affect the task, what waste may be generated, any lifts or requirements for temporary stacking and storing, any concurrent operations to consider. It’s not enough to simply create barricades in anticipation of dropped objects, we must be realistic about what could drop and how it could be caused to ensure we apply the correct control.
- #24 If you wish, show this short video to illustrate just how important it is to consider all hazards at the worksite!
- #25 Discuss the task step by step identifying potential dropped objects, being specific about what could drop and why. How it might drop, what would cause it and when in the task is drops exposure greatest? Discuss prevention, particular the engineered controls. Discuss mitigations and emphasise that all controls must be owned and managed. Let’s look at some of the main controls.
- #26 Cover the key elements of the Tools and Equipment at Height control measures. IMPORTANT: Only approved tools may be used! Never mix and match lanyards with other tools. Create an Inventory, as list of all of the tools in the tool kit. Inspect the tools and ensure all components are in good condition. All tools should be secured to the tool belt or tool bag at all times. Items such as tally books, radios, pens, keys, tape measures must no be carried in pockets where they can fall out. If they are not required, leave them below. When using these tools, it is important that the tools are still identified as potential dropped objects in the risk assessment. Only the tools required for the task should be taken aloft and recorded in the Temporary Equipment at Height Register. Click to show the Form.
- #27 Discuss the use of the Register. It is important to list all tools and equipment and verify that all items have been returned.
- #28 Note that although tools may have lanyards / tethers, they may have individual parts that may become disengaged such as socket wrenches and other tools that are not composite / one-piece.
- #29 Introduce Reliable Securing as part of the Corporate procedure, noting that there are specific requirements to understand and verify that the appropriate OEM fastenings are selected, installed correctly and inspected for any defects. Whilst the DROPS program does not require each of us to become a bolting expert, we can all play a role in supporting pretask equipment inspections and identifying potential for increased risk of dropped objects if any securing component becomes damaged or dislodged.
- #30 Primary Fixing: The primary method by which an item is installed, mounted and secured to prevent the item falling, (eg bolted connections, screws, pins, buckles, clips, welds etc.) Note that this would include the tightness or tension that must be retained in a bolted connection.
- #31 Secondary Retention is defined as the engineered method for securing the primary fixing to prevent loss of clamping force or displacement of fastening components, (eg locking washers, locking wire, split pins / cotter pins, etc.) Also referred to as Second Barrier or Fail Safe feature in some engineering descriptions. Note: Double Lock-nutting or Dual Nutting is NOT recommended as a reliable method for retaining loads in tensioned bolting.
- #32 Safety securing is an additional mechanism for securing the item to the main structure, suitably selected to restrain the item or its components from falling should the primary fixing fail, (eg rated steel or synthetic nets, lanyards, baskets, wires, slings, chains etc.) Note that approved safety nets and safety wires will have tags which display the maximum break load rating.
- #33 Always ensure that secondary retention is installed and functioning. Where there is potential for devices such as nappy pins to be snagged or knocked out, replace with correctly fitted cotter pin.
- #34 All equipment, particularly items at height or equipment used for lifting must have appropriate secondary retention fitted. Ensure you check all equipment prior to use, and seek technical support if you have any queries. >>For example the clevis pins on the cherry picker arm are secured with pins which are bolted to threaded holes. The secondary retention here is critical. Also note that a locking nut is used on the ram.
- #35 Is this a suitable point to secure the safety net?
- #36 Introduce Dropped Object Surveys and Inspections as a key element of the DROPS management system. A picture book is created for each area and features all equipment that is not an integral part of the structure. The description and condition of fastenings is recorded as part of an initial survey, and any failed items are corrected. Typically all items are then inspected on a weekly basis.
- #37 For example, the big bag hoist shown here is featured in Area 3 Mud Tanks book. Note that each fastening on the running beam is recorded and must be inspected, as too is the light fitting above. As per Reliable Securing, the Primary Fixing, Secondary Retention and Safety Securing (if fitted) for each individual item is described and recorded.
- #38 However it is also the responsibility of personnel operating the equipment to ensure all components are in good working order. What do you notice on the hook. What could cause this damage?
- #39 There are many hazards in these areas, including dropped object potential. These areas are enforced as they provide the Isolation control which significantly reduces the exposure of personnel to each of the hazards. Ask the class for examples of areas at the rig site that would be Restricted Access Zones or No-Go Areas / No Entry Zones and how we know where they are and how they are controlled. NOTES: Restricted Access Zones areidentified in the operational permit to work and authorized entrants are limited to the personnel required to perform the work. Areas are marked in RED or signs posted to clearly identify the covered area and specific risk of this zone. Drill floor activities will be controlled and enforced by the Red Zone Marshals – either 3 x floor men or their suitable qualified reliefs. Restricted access zones are shown below and they are not limited to it: • Drill floor • Sub-structure • Catwalk • Material / Chemical storage areas No Go Areas / No Entry Zones are identified in the permit to work, controlled to prevent unauthorized access, and differentiated form the Restricted Access Zones by barricades or signage. No Go Areas / No Entry Zones are shown below and they are not limited to it: • Under lifted loads • Under personnel working at height – with tools or equipment • Under Pick up / lay down machine • Wire line sheaves
- #40 The Red Zone maps are displayed at the worksite for Routine and Non Routine operations. Ask the class, who authorizes access to these areas? Routine Ops: Driller and/or Red Zone Marshall Non-Routine Ops: Driller, Rig Manager or Company Man (CHECK AND CONFIRM – WHY COMPANY MAN?) Ask the classwhat are the key considerations for anyone who is authorized to work in the Red Zone? >> Click to reveal and discuss how this would be managed.
- #41 Ask the class what are the key considerations for anyone who is authorized to work in the Red Zone? >> Click to reveal and discuss how this would be managed. Discuss tasks around well centre that require personnel to be in the vicinity of moving equipment and how complacency should be managed (ie Red Zone Marshall vigilance / follow Marshalls instructions).
- #42 Review each General Requirement of the Company Drops Procedure and acknowledge they are understood.
- #43 Review each General Requirement of the Company Drops Procedure and acknowledge they are understood.
- #44 Review each General Requirement of the Company Drops Procedure and acknowledge they are understood.
- #45 Summarise by inviting delegates to commit to action. >>Reveal the list. The list is not exhaustive. >>Close with Questions and Answers Thank You. I wish you and your colleagues a successful future free from dropped objects.
- #46 Create your own story… but emphasise : DROPS occur Everywhere! Discuss how something like this could occur – or close the session with your own safety message.
