(Part III) (2 of 2) Construction Focus Four: Caught–In or –Between Hazards

How can I protect myself from caught–in or –between hazards?

caught in or between

A. Use machinery that is properly guarded

Never remove a safety guard when a tool is being used. Hazardous moving parts of power tools and equipment need to be safeguarded. For example, belts, gears, shafts, pulleys, sprockets, spindles, drums, fly wheels, chains, or other reciprocating, rotating, or moving parts of equipment must be guarded if such parts are exposed to contact by workers. Be sure to avoid wearing loose clothing or jewelry that can be caught in moving parts.

B. Use other methods to ensure that machinery is sufficiently supported, secured or otherwise made safe

  1. Make sure that your equipment is de-energized and cannot be started accidentally.
  2. Disconnect tools when not in use, before servicing, and when changing accessories such as blades, bits, and cutters
  3. Turn off vehicles before you do maintenance or repair work
  4. Lock out the power source (electric, pneumatic, liquid fuel, hydraulic, etc.) to the equipment
  5. Lower or block the blades of bulldozers, scrapers, and similar equipment before you make repairs or when the equipment is not in use

C. Protect yourself from being pinned between equipment, materials, or other objects

  1. Be aware at all times of the equipment around you and stay a safe distance from it
  2. Never place yourself between moving materials and an immovable structure, vehicle, or stacked materials
  3. Make sure that all loads carried by equipment are stable and secured
  4. Stay out of the swing radius or cranes and other equipment
  5. Wear a seatbelt, if required, to avoid being thrown from a vehicle and then potentially being crushed by the vehicle if it tips over

D. Protect yourself on excavation sites

(a.) Do not work in an unprotected trench that is 5 feet deep or more. The type of protection may be one of the following:

1. Sloping or benching- Sloping is cutting back the sides of the trench to a safe angle so it won’t collapse. Benching uses a series of steps that approximate the safe sloping angle. The angle depends on the soil type

2. Trench box or shield- These do not prevent cave-ins but protect the workers who are in them if a cave-in happens

3. Shoring- Shoring are wooden structures or mechanical or hydraulic systems that support the sides of an excavation.

(b.) Enter or exit a trench or excavation only by using a ladder, stairway or properly designed ramp that is placed within the protected area of the trench

(c.) Do not work outside of the confines of the protection system!

(Part III) (1 of 2) Construction Focus Four: Caught–In or –Between Hazards

What is a caught–in or –between hazard?

When the impact alone creates the injury, the event should be recorded as Struck. When the injury is created more as a result of crushing injuries between objects, the event should be recorded as Caught. Caught- in or -between hazards in construction cause accidents such as cave-ins (trenching), being pulled into or caught in machinery and equipment (this includes strangulation as the result of clothing caught in running machinery and equipment) or being compressed or crushed between rolling, sliding, or shifting objects.

caught in or between

Some of the working conditions that contribute to caught–in or –between hazards include: Machinery that has unguarded moving parts or that is not locked out during maintenance; unprotected excavations and trenches; heavy equipment that tips over, collapsing walls during demolition; and working between moving materials and immovable structures, vehicles, or equipment.

What are the common types of caught–in or –between hazards in construction?

A. Machinery that has unguarded moving parts causing caught-in or -between incidents

If machinery is not properly guarded or de-energized during maintenance or repair, injuries from caught–in or –between hazards may result, ranging from amputations and fractures to death.

When machines or power tools are not properly guarded, workers can get their clothing or parts of their body caught in the machines. If machines are not de-energized (locked out) when they are being repaired, they may cycle or otherwise start up and catch a worker’s body part or clothing and cause injury or death.

Workers can be trapped and crushed under heavy equipment that tips, especially if they are thrown from the equipment.

B. Buried in or by

The major hazard related to Buried in or by is cave-ins of unprotected trenches and excavations. Cave-ins crush or suffocate workers.

In addition, trenches may contain hazardous atmospheres; workers can be drown in water, sewage, or chemicals in the trenches; and if working around underground utilities, workers may also face burns, electrocution or explosions from steam, hot water, gas, or electricity.

Workers who are working underneath large scaffolds may also be buried if the scaffolds collapse. Workers may be buried and crushed by walls that collapse during demolition.

C. Pinned between

You can be pinned

  1. between equipment and a solid object, such as a wall or another piece of equipment
  2. between materials being stacked/stored and a solid object, such as a wall or another piece of equipment
  3. between shoring and construction materials in a trench

These types of hazards can result in multiple broken bones, asphyxiation, or death.
