THE TRUE DANGER OF CONFINED SPACES

Just how dangerous are confined spaces? Aren't all the warnings and procedural checks simply overkill? Hardly. Think about this: According to a study performed by Safety Sciences, the following types of confined space incidents resulted in injuries and/or fatalities:

 
Type of Event
Number of Events
Number of Injuries Only
Number of Fatalities
Atmospheric Conditions (lack of oxygen)
80
72
78
Explosion or Fire
15
49
15
Explosion or Fire at Point of Entry
23
20
32
Electric Shock
11
2
9
Trapped in Unstable Material (cave in)
16
0
16
Struck by Falling Objects
15
1
14

These numbers should tell you something:

Fifty four % of the people exposed to oxygen deficient conditions died.

For every fire within a confined space, one person died.

Fire at the point of entry caused multiple fatalities in a single event.

Cave-ins left 100 % of the victims dead.

Still think the safety rules pertaining to confined spaces are overkill? It is important to know what you are getting into. Has the space been recently inspected by certified industrial hygienist, marine chemist or shipyard competent person? Have instruments been used to determine the presence or absence of combustible or flammable vapors? Do these instruments show the oxygen level to be between 19.5 and 22%? Is a "safe for hot work/safe for workers" permit required? Are the conditions of the permit or certificate being followed to the letter?

Are the contents of the space stable? Construction workers beware. Confined spaces are not limited to tanks and the like. Trenches, utility vaults, and large diameter pipelines all present similar dangers. In fact, trench cave-ins are a leading cause of construction fatalities.

Confined space work is dangerous. However, it can be done safely if appropriate precautions are taken. The hazards in most cases are invisible, so take those precautions before entering.
