DROPPED OBJECTS

WHAT TO DISCUSS



The process of implementing WDI standard to prevent injury and or damage
caused by falling objects
This standard is intended as a guide to eliminating the incidence of dropped
objects within drilling derrick structures, areas below the rig floor, and from
cranes. As such, the overall objectives of the DROPS program are:
 Eliminate injury to people.
 Eliminate the incidence of damage sustained by dropped objects.
 Eliminate damage to other associated equipment.

BMS 06-42-STD – Dropped Objects Prevention Program
To recognize your personal responsibilities for the prevention of dropped objects
Everybody; Employers, Workers, Drivers, Suppliers, Designers, Maintainers etc. have a
moral and legal responsibility to carry out their activities in a safe manner

RESPONSIBILITIES






3

 Senior Toolpusher
The STP will coordinate the implementation of the DROPS and track the progress at
the rig.
The STP is responsible for this procedure being followed and that all checks,
inspections and maintenance on equipment is completed in a timely manner and to
the standards described in this document and other relevant BMS requirements.
The STP shall monitor the use and success of the program based on the criteria set
out in this procedure, maintain records in the DROPS file for each rig, and review the
performance of the DROPS for the rig and report the findings to the Rig
Superintendent every month.
 Rig Crew
The rig crew is responsible for identifying potential dropped objects, methods of
securing these potential objects and removing redundant equipment from the
worksite.

WHAT IS AN DROPPED OBJECT?
Dropped Object: Any object that falls from its previous static position under its own weight
Dropped Object Static: A static dropped object is one that was at rest initially but falls from
its original position under its own weight. Eg. A nut dislodging in the mast, a light fixture
working loose over time.
Dropped Object Dynamic: A dynamic dropped object is a solid object that breaks free from
its original position resulting from human intervention or other immediate outside
influence/impact on the object. Eg. A top drive hitting the rig floor, a light fixture on a crane
boom that collides with something resulting in the fixture being dislodged, separating and
falling.
Red Zone: The zone or area on a drilling rig that has high potential for dropped objects in
addition to other high risks associated with rig operations. The Red Zone will be a virtual
zone identified on a Red Zone map and displayed on each rig.

HOW BAD IS THE PROBLEM

At Work:
“Dropped Objects are among the Top 10 causes of Fatality and Serious
Injury in the Oil and Gas Industry”
At Home:
“The top three causes of fatal accidents are… fall from height…being
struck by moving vehicles…and being struck by falling objects”

DROPPED OBJECTS FACTS

6

POTENTIAL KILLERS
Items found in Mast during initial survey

Potential Dropped Object Areas:

INCORRECT

Slings supported on the pin not
the bow of the shackle and no
mousing. Safety shackles should
be used.

Corroded split pins should be
replaced with stainless steel pins.
9

INCORRECT

Poor nut
penetration
No safety sling

Missing split pin
Poor
housekeeping
Loose nut
No safety sling

10

WATCH FOR

Grease build up

11

loose drill line lubricant

WATCH FOR

Corrosion

Clamp Not build
for purpose
Design.
12

WATCH FOR
Bad practice, bolt can fall
if nut comes loose

13

Cracked Paint –
Indicates structural
movement

POOR HOUSEKEEPING
INCORRECT
No lanyard Attached, Stainless Steel bolts
Provide
Better protection

14

Rubbish Allowed To
build Up
in the Mast beams

WORN RIGGING

Worn or Damaged Rigging Should be Removed from service If >10% wear
(Rule of thumb If you can see Wear remove The item).

15

WORKING TO MAKE A SAFER WORKPLACE

Manage Dropped Objects Incidents:
• Inspect your worksite and Identify Dropped Objects Hazard.
• Any unnecessary rigging equipment shall be removed to reduce
the potential for dropped objects.
• All Tools/Equipments should be Checked and Secured before they
are taken up at height.
• Derrick inspection every rig down and rig up for potential dropped
objects.

WORKING TO MAKE A SAFER WORKPLACE

Manage Dropped Objects Incidents:
• When working at height always tie off hand tools.
• Check all lifting equipment before use.
• When raising or laying down equipments check there are no loose
items.
• Report any defective equipment to supervisor immediately.
• Supervisors to follow working at height procedure for all work
above 2 meters.

WORKING TO MAKE A SAFER WORKPLACE

Potential Dropped Object Areas:
Ensure Chocks are
raised and pins are
secure

Ensure all suspended equipment
has safety pins fitted in the
shackles, Note all shackles used
at height should be 4 part

WORKING TO MAKE A SAFER WORKPLACE

Potential Dropped Object Areas:
Check safety pins are
fitted to all shackles

Check all hoses hanging have
safety clamps fitted to avoid
dropped objects

WORKING TO MAKE A SAFER WORKPLACE

Potential For Dropped Object:
No safety wires
attached

Rusty, cracked hinges could cause
door to fall off.

WORKING TO MAKE A SAFER WORKPLACE

Potential For Dropped Object:
Damaged slings can cause
dropped objects

Damaged slings can cause
dropped objects

STOP WORK AUTHORITY

You should Always:
• Look after Yourself.
• Look after the People around you.
If You Think The Work Is Unsafe

STOP

ON THE JOB TRAINING



Controlling the hazards associated with dropped objects requires training for rig
crews



Crews need to be familiar with the rig equipment and understand what controls
are in place to prevent dropped objects, these must be specified

Review SP-2097 well
engineering
Specification for the
dropped
Objects
requirements.
23

TOOLS AT HEIGHT

 The “Tools Aloft” log sheet provides a means of controlling the use of
hand tools in the mast
 Any tools used in the mast should be tied off and returned to its proper
storage area as soon as a job is completed

24

In Rig – starts using effective & innovative tools.

Our TEAM focus is to REDUCE or ELIMINATE Incidents &
Hurts to personnel.

25

Most of the incidents are DROP objects

26

Using innovative tools prevent hurt to someone

27

Secured tools in use

28
