Confined Space Safety!

The Dangers of Confined Spaces

Confined spaces such as underground petroleum storage tanks are among the most hazardous work environments. Oxygen deficiency, toxic vapors, and the risk of fire or explosion can incapacitate a worker within seconds. Physical hazards—such as limited entry and exit points—make rescue efforts extremely difficult. A recent tragedy in Palm Beach County, where a worker died after a medical emergency inside a gasoline storage tank, underscores the life-threatening risks when proper precautions are not taken.

​

Safety and Training Requirements

Before anyone enters or performs maintenance on an underground tank, strict safety procedures must be followed. OSHA’s Confined Space Standard (29 CFR 1910.146) requires employers to:

• Provide confined space entry training.

• Test and monitor air quality before and during entry.

• Ensure proper ventilation and use of protective equipment.

• Maintain an attendant outside the space and have a rescue plan in place.

Industry guidance from organizations such as NFPA and API further reinforces safe practices, particularly regarding flammable atmospheres. Employers must also keep a written permit system for entry and ensure all personnel are trained to recognize hazards and respond to emergencies.

The Lesson is Clear . . .

No one should ever enter an underground petroleum storage tank  without comprehensive training, atmospheric testing, protective equipment, and a prepared rescue plan. Compliance with OSHA and industry standards is not optional—it is essential for saving lives.
