Good example iWire.
Here is what the 70E says:
110.1 Relationships with Contractors (Outside Service Personnel, etc.).
(A) Host Employer Responsibilities:
(1) The host employer shall inform contract employers of:
a. Known hazards that are covered by this standard, that are related to the contract employer?s work, and that might not be recognized by the contract employer or its employees
b. Information about the employer?s installation that the contract employer needs to make the assessments required by Chapter 1
(2) The host employer shall report observed contract employer- related violations of this standard to the contract employer.
(B) Contract Employer Responsibilities:
(1) The contract employer shall ensure that each of his or her employees is instructed in the hazards communicated to the contract employer by the host employer.
This instruction is in addition to the basic training required by this standard.
(2)
The contract employer shall ensure that each of his or her employees follows the work practices required by this standard and safety-related work rules required by
the host employer.
(3) The contract employer shall advise the host employer of:
a. Any unique hazards presented by the contract employer?s work,
b. Any unanticipated hazards found during the contract employer?s work that the host employer did not mention, and
c. The measures the contractor took to correct any violations reported by the host employer under paragraph (A)(2) of this section and to prevent such violation from recurring in the future.
(C) Documentation. There shall be a
documented meeting between the host employer and the contract employer.
So the owner of the system (In the case of the OP that would be the company Jimbo works for) is required to:
1) Identify hazards (Arc flash labels from the study for the OP)
2) Ensure the EC follow the 70E requirements and any additional requirements the OP's company may have in thier safety program (Does not sound like this was done)
3) Report any observed violations of the 70E or it's own safety requirements (Obviously Jimbo tried to do this, as he should have)
3) Hold a meeting with the EC covering the safety requirements and document it (Does not sound like this was done either)
If the owner of the system does all of these things they will likely not be held liable in the event of an accident on thier property involving a contractor, but if these are not done they can be held liable (IBM found out the hard way to the tune of a few million bucks).
Sooooo, to protect themselves many companies use this form (Attached) to pre-qualify EC's before they are allowed to come on site.
