Introduction

!

This course describes the procedures to follow whenever aoperations installation crew, supervisor, subcontractor or menter a confined spaced as outlined in OSHA 1910.146, 1926and Section 3.10. Confined Space in Construction SOP (SolaManual).

!

OSHA definition of confined space –- Is large enough and so configured that an employee can bodily e

it;

- Has limited or restricted means for entry and exit;

- Is not designed for continuous employee occupancy.


7/58

!

Protection of the employee from the hazards within confin- Mandates general and specific requirements for:

- Safe work practices

- Layered atmosphere – spaces that are deep or have areas leadithe entry point may cause the atmosphere to be layered.

- Testing must be done in the area surrounding the worker.

- Test is to be done at 4 feet in the direction of travel and to

At h i T ti P d ( ti


50/58
