The Process of Confined Space Entry
What is a Confined Space?
OSHA has a three-part definition for a confined space:
- The space must be “large enough and so configured that an employee can bodily enter and perform assigned work” AND…
- The space must “have limited or restricted means for entry or exit” AND…
- The space must not be “designed for continuous employee occupancy.”
Before entry, the appropriate steps to work within a confined space need to be written, communicated, evaluated and reviewed.
Our process for industrial confined space cleaning is tailored to various hazards, extractions, the physical space, the work to be completed, and proper personnel training. First Environmental provides trained and certified entry personnel and confined space cleaning services for our clients.
