If you've logged into ISNetworld and found a stack of reviewer comments waiting for you, you already know the frustration. Work is on hold. Your client is waiting. And the comments themselves can feel vague, circular, or just plain hard to decode without platform experience.
This guide walks you through exactly how ISNetworld reviewer comments work, what the most common categories are, how to respond correctly, and how to avoid getting flagged again on the next renewal cycle.
What Are ISNetworld Reviewer Comments?
When you submit documentation through ISNetworld, a team of ISN reviewers evaluates your submissions against client-specific requirements. When something doesn't meet those requirements, they leave a reviewer comment explaining what's missing or incorrect.
These comments aren't optional feedback. They're blockers. Until you address them and resubmit, your account won't reach approved status, and your client can't authorize you to work.
The challenge is that reviewer comments vary widely. Some are straightforward ("missing signature on page 4"). Others are technical ("OSHA program does not meet the required elements for a written hazard communication program"). And some feel contradictory, especially if you've already submitted what you thought was the right document.
Why Reviewer Comments Pile Up
Most contractors don't have a dedicated ISN administrator. The person handling the account is often the safety manager, the office manager, or even the owner, all juggling other responsibilities. When a comment comes in, it gets added to the pile.
The other common issue: submitting the wrong version of a document. ISNetworld's RAVS (Review and Verification Services) has specific requirements for what a written program must include. A generic OSHA template pulled from the internet may not hit all the required elements, and you'll get it kicked back every time until the gaps are filled.
Renewal deadlines make this worse. If your annual renewal is approaching and you have unresolved comments, your score drops and your approval lapses, which can directly affect your ability to work for the clients who require ISN qualification.
Step-by-Step: How to Resolve ISNetworld Reviewer Comments
Step 1: Read the Comment Carefully Before Doing Anything
This sounds obvious, but many contractors respond to reviewer comments by immediately resubmitting the same document or uploading something adjacent to what was asked for.
Read the comment word for word. ISN reviewers are usually specific. If they say "the written program does not address [specific element]," they mean that exact element is missing. If they say "signature required," they mean a wet or typed signature on the document itself, not a cover letter.
Note whether the comment references a specific OSHA standard or a client-specific requirement. Those require different responses.
Step 2: Identify the Comment Category
ISNetworld reviewer comments generally fall into a few categories:
Documentation gaps. The required written program exists but doesn't cover all the elements the reviewer is checking against. Common examples include hazard communication programs missing a section on labeling, or lockout/tagout programs that don't address energy control procedures in enough detail.
Missing signatures or dates. Programs need to be signed and dated by someone with authority (typically a company officer or safety director). Undated programs or programs signed by the wrong person get flagged.
Wrong document type. The reviewer asked for a specific program or certificate and received something else. This often happens when contractors upload a training record instead of a written program, or a certificate of insurance when a specific endorsement was required.
Expired documents. Certificates, training records, and insurance documents all have expiration dates. If anything has lapsed, it needs to be renewed and resubmitted.
OSHA recordkeeping issues. OSHA 300 logs, 300A summaries, and TRIR calculations are a frequent source of comments. Errors in the math, missing company officer certifications on the 300A, or incomplete log entries will all generate flags.
Client-specific requirements. Some of your clients have added custom requirements on top of the ISN baseline. These show up in your account under the specific client's requirements section. If you're not checking those separately, you may be compliant with ISN's standard but still failing a client requirement.
Step 3: Fix the Root Problem, Not the Symptom
The fastest way to stay stuck in reviewer comment cycles is to patch documents without fixing the underlying gap.
If your hazard communication program keeps getting flagged, the fix isn't to reformat it. The fix is to compare it line by line against the OSHA 29 CFR 1910.1200 standard and the ISN RAVS checklist for that program type, then add the missing elements.
If your OSHA 300A keeps getting rejected, check whether a company officer has certified it (required by OSHA), whether the dates are correct, and whether the average employee count is calculated properly.
Taking an extra 20 minutes to do a thorough revision saves you from going back and forth with reviewers three or four times.
Step 4: Resubmit With a Clear Response Note
When you resubmit a document, use the response field to briefly explain what you changed. Something like: "Updated Section 4 to include labeling procedures per 1910.1200(f). Signature added by company officer on page 1."
This helps the reviewer quickly verify that you addressed the comment rather than just re-uploading the same file. It also creates a paper trail if the same comment comes up again.
Step 5: Track Your Open Comments in One Place
If you have multiple clients on ISNetworld, each with their own requirements, comments can accumulate across different sections of your account. Build a simple tracking sheet that lists each open comment, the document it relates to, the action needed, and the status.
This doesn't need to be complicated. A spreadsheet with five columns works fine. The goal is to make sure nothing falls through the cracks during a busy stretch.
Step 6: Set a Response Timeline
ISNetworld doesn't always give you a hard deadline to respond to reviewer comments, but your clients often do. If a client has a mobilization date or a contract start date, that's your real deadline.
Aim to respond to any new reviewer comment within 48 to 72 hours. The longer comments sit unaddressed, the more likely they are to affect your account score and your standing with the client.
Common RAVS Program Gaps That Trigger Repeat Comments
If you're seeing the same types of comments cycle through every renewal, these are the programs most often flagged during RAVS review:
Hazard Communication (HazCom/GHS). Missing sections on SDS management, labeling procedures, or employee training documentation.
Lockout/Tagout (LOTO). Programs that describe the general process but don't include equipment-specific procedures or annual inspection records.
Respiratory Protection. Missing fit test records, medical evaluation documentation, or a written program that addresses the specific respirator types in use.
Fall Protection. Generic programs that don't address the specific work types your company performs (roofing vs. scaffolding vs. leading edge work, for example).
Hearing Conservation. Missing audiometric testing records or noise exposure monitoring data if your work involves high-noise environments.
Drug and Alcohol Policy. Missing testing protocols, supervisor training documentation, or language that meets client-specific requirements (especially in oil and gas).
If any of these apply to your work scope, it's worth doing a full review of those programs now rather than waiting for the next comment cycle.
How to Avoid Reviewer Comments at Renewal
The best time to address documentation gaps is before your renewal window opens, not after comments start coming in.
A few practices that reduce comment volume at renewal:
- Review your expiring documents 60 to 90 days before renewal. Insurance certificates, training records, and drug testing documentation all have predictable expiration dates.
- When you update a written program, date it and have it signed before uploading. Don't upload drafts.
- Check client-specific requirements at least once per quarter. Clients can add or modify requirements between your renewal cycles.
- Keep a version history of your programs. If a reviewer questions whether a change was made, you want to be able to show the revision.
When to Get Help With ISNetworld Reviewer Comments
Some situations are worth handling yourself. Others are worth getting expert support.
If you're dealing with a backlog of unresolved comments, a renewal deadline approaching, or a client threatening to remove you from their approved vendor list, the cost of slow resolution is real and measurable. Billable work you can't access because your account isn't approved is a direct financial loss.
Contractors who work with a firm that knows ISNetworld, RAVS requirements, and the specific documentation standards for oil and gas, construction, and manufacturing can clear comment backlogs faster and build programs that hold up on future reviews.
PrecisionEHS works directly with contractors on ISNetworld, Avetta, and Veriforce accounts, handling reviewer comment resolution, RAVS program development, and ongoing prequalification maintenance. If your account has open comments or an upcoming renewal that's at risk, that's exactly the kind of situation worth a conversation.
Reviewer comments don't have to stall your work. Most of them have clear, fixable causes. Address the root issue, resubmit with a clear explanation, and build a documentation process that keeps your account clean between renewals.
