1 1 Struck-By/Caught-Between Module 4

2 2 DISCLAIMER This material was produced under grant number SH from the Occupational Safety and Health Administration, U.S. Department of Labor. It does not necessarily reflect the views or policies of the U.S. Department of Labor, nor does mention of trade names, commercial products, or organizations imply endorsement by the U.S. Government.

3 3 Objectives After this module you should be able to – identify the most common struck-by and caught-between hazards – take the necessary steps to avoid those hazards

4 4 First, Let’s Talk About Struck-By’s A struck-by is an accident in which any part of the body is struck by an object that is in motion, whether moving, swinging, flying, falling, etc.

5 5 Struck-By Hazards Site clearing Moving pipe and casing Using tongs and spinning chain Falling overhead objects Working around mobile equipment Loads being moved Improper use of hand tools Whipping pressurized lines Using elevators Using turnbuckles and load strapping

6 6 Tree Felling Struck-By’s Figure out the best felling direction Plan, clear, and use an escape path Figure out the proper hinge size Use proper controlled felling techniques Maintain safe separation distances from other workers or machines Wear required PPE Danger! Tree felling requires special training!

7 7 while the rig is being set up at the site, workers can get struck by a crane, load, truck, forklift, tool, etc. it’s important that the worker is knowledgeable of the hazards present and is aware at all times of equipment around them

8 8 a worker can get struck by moving, swinging, or falling drill pipe stand clear of this area when pipe is being lifted to the rig floor

9 9 while tripping in/out, a worker can get struck by tongs or spinning chain always determine and stand clear of the swing radius of these items when possible [see next slide]

10 10

11 11 if connections break free, high-pressure lines and hoses can quickly become struck-by hazards ensure that lines and hoses are properly secured, connections are not worn, and whip-checks are installed

12 12 a small crack or other damage to a hand tool can cause a struck-by incident Corrective Actions: inspect tools before use; take defective tools out of service

13 13 cable used to rig this load up may suddenly snap, slicing anything in its path as much as possible, stand clear of the cable while it is under stress

14 14 a tool stuck through the middle of a turnbuckle to tighten it can kick back and strike you use a crescent wrench at one end of the turnbuckle to tighten it

15 15 this load could shift or fall suddenly striking or falling on the worker Corrective Action: a tag line would be ideal here; take the time to set one up before the lift

16 16 this is another example of where a tag line should be used

17 17 if they attached the tag line to the load rather than the rigging, these employees would be correctly using a tag line

18 18 while working at heights, if you loose your grip on a tool, it could fall onto a worker or equipment use a device like this or simply use a tail rope to keep tools from falling

19 19 Now, Caught-Between’s A caught-between is an accident in which the whole body or part of the body is pinched or crushed between objects.

20 20 Caught-Between Hazards Moving pipe and casing Using tongs and spinning chain Working around mobile equipment Unguarded moving parts Working under suspended loads Improper use of hand tools Wearing loose clothing Improper handling of slips or elevators

21 21 crushing hazards can exist when setting up the rig always stand clear; keep hands and other body parts away

22 22 while tripping in/out, a worker can get caught between tongs or spinning chain

23 23 worker’s fingers or hands can get smashed when setting the slips always keep hands on the handles

24 24 workers’ hands or thumbs can get caught between the elevator and the stump always place hands on designated handles

25 25 this worker is cutting through a bad spot while the truck is moving Corrective Actions: never take chances like this when the space is this limited; wait until the truck parks

26 26 always use a spotter when what is behind you cannot be seen

27 27 belt and pulleys of machines are common pinch points ensure that the guarding is installed; do not place hands in the area while machine is operating

28 28 choking up on tools and smashing fingers is very common the first 6” of this handle is painted red to indicate that hands should not be placed there

29 29 this employee is using proper hand placement on a sledge

30 30 hands and fingers can get caught while maneuvering stands of pipe what can a worker do to keep hands from getting pinched or crushed?

31 31 this worker is using a tag line, keeping his hands free from crushing hazards when your hands get to the end of the tagline, there should be a knot for grip Warning! The next slide contains graphic content.

32 32 here’s what could happen

33 33 Corrective Action: do what needs to be done before the load is suspended or use blocking

34 34 Your Employer Is Responsible For Providing appropriate PPE and other appropriate safety equipment Providing tag lines and tail ropes Ensure equipment is properly guarded Replacing tools that are worn or damaged

35 35 You Are Responsible For Wearing the appropriate PPE Operating and working around mobile equipment carefully, keeping in mind that such equipment has blind spots Using caution when working around potential struck-by or caught-between hazards

36 36 Case Study Because the company failed to do inspections, the crown sheave shaft came out of one of its mounts releasing the sheaves, the drilling line, and 165,000- pound drill-string. These components fell to the drilling floor killing two workers.

37 37 Case Study A dump truck driver was attempting to repair a leaking brake line. When the hydraulics failed, the dump bed came down and pinned him to the chassis. He died from extensive internal bleeding shortly after EMS unpinned him.

38 38 Always Remember Secure or remove any loose equipment before setting up or breaking down a rig Be aware of and do not enter the swing radius of tongs and/or spinning chain Take damaged tools out of service Don’t choke up on tools Never work under a suspended load Ensure machine guarding is in place Never wear loose clothing

39 39 Memory Check 1.How should a person on the ground control a suspended load being moved? a.use a pole with a hook on the end b.grab the rigging c.grab only the load d.use a tag line

40 40 Memory Check 2.Which of the following is NOT a step in controlling pressurized lines? a.install whip checks b.match thread and size of connections c.test connection by running an extremely high pressure through the line d.ensure connections are not worn or damaged

41 41 Memory Check 3.How many seconds is it acceptable to stand under a suspended load? a.0 b.1 c.2 d.3
