An april release from the OSHA quick-takes shows another great example of the dangers of trench collapses. In this example – OSHA claims that just minutes after an OSHA officer stopped work on an 8 foot trench, it collapsed. This collapse was particularly mind-blowing, due to an unnamed employee arguing with the OSHA officer literally 3 seconds before the trench collapses. A video transcript :
OSHA Officer : “This is a good demonstration as to why you’re not supposed to be down there without caving protection…”
Employee : “I understand that, but when we also would’ve seen any type of movement, we would have been out of there and been able to excavate it out before it happened….and I know it’s a…a “what-if” on both ends…”
**3 Seconds Elapses…**
**Trench Collapses**
OSHA Officer : “I mean I wouldn’t wanna be down in there when that happens…and it’s hard to judge when those things happen.”
You can see the fissure on the left side of the trench, about 0.5″-1″ wide which gradually grows during the course of the video. While this particular example seems underwhelming, keep in mind that this trench is approximately 8 feet deep, Earth falling on you from above is never a good thing no matter what quantity.
To raise awareness and prevent accidents like this, OSHA provides specific information on Trench and Excavation in their usual format, laid out to answer any questions you have regarding this.
- What OSHA standards apply to trenching and excavation?
- What information is available to the construction industry regarding trenching and excavation?
- What are the potential hazards and possible solutions associated with trenching and excavation?
- What additional information is available regarding trenching and excavation?
Additionally, OSHA Directive CPL 02-00-069 [CPL 2.69], (1985, September 19). Establishes a National Emphasis Program (NEP) for the programmed safety inspection of trenching and excavation operations.
