Cold Open — The Shipment

Receiving Dock // 07:40 CST // Midland, TX

An SDS That Doesn't Match

You are Priya Nair, Safety Coordinator at Crestline. Three months in. Five weeks post-OSHA inspection, the overnight freight from Harmon-Peak just rolled in — two totes of Solvatex-550 for Blend Line 2's 09:00 run. SDS in the pouch is dated November 2025. The invoice references a Rev 7 Classification Update Bulletin Harmon-Peak issued five weeks ago. Jordan is unreachable until 09:15.

OPS

07:35 CST — Harmon-Peak freight #HP-01-12927 at Dock 2. Two 275-gallon IBC totes Solvatex-550 (CAS 64742-47-8). Driver gone 07:38.

Priya

Opened the pouch to pre-stage the SDS check. Standard. Fifteen seconds later I'm holding an SDS dated November 2025. Pre-HCS 2024.

Priya

And the invoice cites a 'Rev 7 Classification Update Bulletin 2026-CR-44-INT' Harmon-Peak sent on December 1st. The SDS in my hand doesn't reflect it.

Priya

Blend Line 2 starts a CR-44 run at 09:00. Mike's on the floor. Jordan's in the acquisition briefing — 'trust you until 09:15.' It's 07:40.

Legal Anchor

The first-shipment-after-update rule under 1910.1200(g)(6) is the core duty here: the January 12 shipment is the first shipment after Harmon-Peak's December 1 bulletin. The SDS in your hand is the SDS that should have been updated.

Decision 1 of 3 // The 09:00 Production Run

The 09:00 Production Run

Blend Line 2 is scheduled to start at 09:00 — 80 minutes from now. The SDS on the shipment does not reflect the supplier's own reclassification. Operators' Solvatex-550 training records reference the old classification. What do you do in the next 20 minutes?

Activity 1 of 3 // SDS Redline

Harmon-Peak SDS — Rev 3 vs Rev 7 Bulletin

You've pulled the Harmon-Peak bulletin. Compare the Nov 2025 SDS against the Dec 1, 2026 Rev 7 summary. Find the 4 genuine changes before you call. One row is unchanged.

Tap any right-column cell that's a real change. Each flag toggles. Wrong flags and missed flags both count against you. Manufacturer classification duty — 1910.1200(d)

Flagged as changed: 0 of 4 target differences

Activity 2 of 3 // Inbox — 08:00 to 08:15

Triage Eight Emails Before the 08:30 Call

Eight emails have arrived in the last 15 minutes. Sort each into Urgent / Important / Routine / Ignore. Your next phone call with Daniel Oyelaran at Harmon-Peak is at 08:30 — what you action here shapes that call. Distributor duty — 1910.1200(g)(7)

Decision 2 of 3 // Daniel's Callback // 08:30

Daniel's Callback — 08:30

Daniel

Priya, I owe you an apology. Rev 7 SDSs have been in our legal review since the December 1 bulletin — they go out this week, and yes, yesterday's shipment should have had the new version. We can email the updated SDS by close of business today. Printed copy is in certified mail, with you Friday.

What do you commit to?

Narrative // The Harmon-Peak Call — After // 08:44

Three Bars, Three Directions

Priya

08:44. Call ended two minutes ago. HUD shows three bars, three directions. I pushed Harmon-Peak, bar moved. Held the line for our customers, bar moved. Jordan will see what I decided.

Mike

(floor radio) Priya — are we running at 11:00 or done for the shift?

Priya

Solvatex-550 SDS handled. Totes handled. But Linfield's email is still open — they're asking about OUR CR-44 SDS. If Harmon-Peak held Rev 7 back for five weeks, what are WE holding back from OUR customers?

OPS

CRESTLINE CUSTOMER PORTAL — 47 active CR-44 customers. 12 haven't reordered since Dec 20, 2026. They still have the pre-reclassification Rev 3 SDS on file.

Legal Anchor

Under industry best practice, when a manufacturer updates an SDS for a classification change, proactive customer notification (not waiting for the next shipment) is the defensible standard. (g)(6) sets the floor; practice sits above it.

Activity 3 of 3 // Trace the SDS — Our Side

Audit Crestline's Outbound SDS Flow

Crestline is the mirror image of Harmon-Peak for our CR-44 customers. Trace the path of our Rev 7 CR-44 SDS through Crestline's system to the downstream customer. At each transfer point, choose: Approve (flow continues), Flag (intervention needed), or Interrupt (break the flow until resolved). 7 transfer points. Correct answers: 5 approvals, 2 interventions.

Decision 3 of 3 // The Downstream Twelve

The 12 Customers Who Haven't Reordered

Your data flow audit surfaced it: 12 active CR-44 customers have not reordered since December 20, 2026 and therefore hold the pre-Rev-7 Crestline SDS. They can see the Rev 7 on the portal — if they log in. Today you just experienced the exact same blind spot from the Harmon-Peak side. How do you handle the downstream?

09:15 — Jordan Is Out

OPS

Summary — January 12, 2027, 07:40–09:15 CST. Shipment received. Discrepancy identified. Production status resolved. Supplier remediation initiated. Downstream exposure identified.

Jordan

(walking into the coordinator office, coffee in hand) Okay, tell me what happened.

Priya

Solvatex-550 came in with a November 2025 SDS. Harmon-Peak had reclassified it in December. I called Daniel. I made three decisions. Here they are.

Jordan

And the downstream side?

Priya

Twelve of our CR-44 customers haven't reordered since the update. They have the old SDS.

Jordan

What did you decide?

The Shipment — Defensible Close

Defensible on Both Sides

--

You held Harmon-Peak to account, preserved defensibility for Crestline's own customers, and did it without interrupting Jordan. This is what Safety Coordinator judgement looks like under pressure.

The Shipment — Mixed Outcome

Partially Closed

--

You met the regulatory floor. You did not exceed it. The supplier side is handled. The downstream side is only half-addressed.

Module complete. Continue when you're ready.

The Shipment — Poor Close

Compounded Exposure

--

You chose the production schedule over the regulation — and the regulation was not ambiguous. The post-abatement window amplifies what comes next.
