The technician typically worked alone, traveling site to site as a one‑person team. At the micro level, the investigation highlighted several immediate issues: the technician did not have the proper ladder, was not fully using the required PPE, and no air testing or lockout/tagout had been performed, even though mechanical equipment and stored energy were present in the space. The team could not agree on whether the space was permit‑required or not, and the incident quickly turned into internal conflict instead of clarity.

When we stepped back to look at the macro level, a more fundamental problem emerged. The company’s written confined space SOPs were largely aligned with regulatory requirements and clearly stated that permit‑required confined space work should involve a minimum of two, preferably three, people. Yet in practice, service technicians were routinely dispatched as lone workers to spaces that could easily meet permit‑required criteria. In other words, even if this technician had perfect PPE and the right ladder, he was structurally set up to fail.

By connecting both levels, we helped them see that the issue wasn’t just field execution, it was also how the work was organized and staffed. Together, we identified changes such as evaluating spaces before dispatch, assigning two‑ or three‑person teams for higher‑risk work, and engaging facility personnel in rescue and emergency communication protocols where appropriate. The result was a safer, more defensible approach where lone worker exposure in and around confined spaces was no longer treated as business as usual, and the written program and real‑world practice finally matched.
