Why a R50,000 Subcontractor Could Cost You R2 Million: The Invisible Risks of Hiring Expertise

Learn the 3 mandatory documents — Section 37(2), COIDA, and Public Liability cover — that protect your business from subcontractor accidents and claims.

When a subcontractor walks onto your site, their mistakes can become your bill.


A subcontractor arrives at your facility to complete a routine maintenance task—a job valued at a modest R50,000. It is a standard procedure, the kind that happens every week. However, on his way out, the subcontractor’s vehicle strikes your specialized electric gate. The damage is immediate and significant: R150,000 to repair the entry system.

If that subcontractor hasn't provided proof of insurance in their Safety File, the financial fallout is yours alone. Your company’s insurance provider won't cover the claim because the damage was caused by a third party. If the subcontractor lacks the liquid capital to pay, that R50,000 project has just cost you R150,000 in repairs.

But as an OHS consultant, I have seen far worse. While R150,000 is a painful hit to the bottom line, it is a rounding error compared to the R2 million catastrophe that occurs when a single welding spark meets a warehouse roof or a crane drops a load through a structural ceiling. In these moments, paperwork isn't just bureaucracy—it is the only thing standing between your company’s survival and a subcontractor's crushing debt.

The "Accidental Employee" Trap: Section 37(2)

In my years auditing industrial sites, I’ve found that the most dangerous misconception is the belief that "hiring out" a task automatically "hires out" the legal responsibility for safety. In reality, the moment a subcontractor steps onto your site, you are exposed.

Under health and safety law, a subcontractor and their staff can be "deemed" your employees if an accident occurs. To prevent this, a Section 37(2) Agreement is mandatory. This document is the legal mechanism that shifts responsibility, explicitly stating: "You are responsible for your own safety while on our premises."

Without this signed agreement tucked safely inside a verified Safety File before work begins, your company effectively adopts the subcontractor’s workforce. If an injury occurs, you inherit three immediate and expensive responsibilities:

  1. Direct Medical Treatment: You are responsible for the immediate care of the injured party.
  2. Private Hospital Costs: You must cover the costs of admitting them to a private hospital for an Injury on Duty (IOD).
  3. COIDA Administration: You must handle the Compensation for Occupational Injuries and Diseases Act (COIDA) administration on their behalf.

"If you don’t check their insurance, their accident becomes your debt."

The COIDA Catch-22

Allowing a contractor onto your site without a valid "Letter of Good Standing" from the Compensation Fund is a disaster waiting to happen. This is the only proof that the subcontractor is authorized to receive treatment under their own insurance.

Ignoring this creates a "Catch-22" during a medical emergency. Most private hospitals will flatly refuse to admit injured personnel without proof of COIDA cover. If a subcontractor’s employee is seriously injured on your watch and lacks this cover, you are left with an injured person on your floor, no hospital admission, and a massive legal liability. Checking for this letter is a non-negotiable prerequisite for site access. No letter, no entry.

Public Liability: Protecting Your Pockets, Not Just People

While COIDA protects the person, Public Liability Insurance protects your pockets. It is designed to cover damage to property or third parties caused by the subcontractor’s negligence.

As we saw with the gate example, the scale of potential loss often dwarfs the value of the contract. Consider the risks:

  • The Welding Spark: A R2 Million warehouse fire.
  • The Structural Fail: A crane dropping a heavy load onto a roof.
  • The Routine Collision: The R150,000 gate repair.

If the contractor does not have insurance, the financial burden of these accidents falls directly on you. To manage this risk, I recommend implementing a Standard Operating Procedure (SOP) that sets a mandatory minimum cover amount—such as R5 Million Public Liability Cover—for every subcontractor, regardless of the job size. A subcontractor may possess high-level technical expertise, but for your company’s survival, their financial compliance is just as important as their trade skill.

The Weekend Vulnerability Gap

Risk is not constant; it fluctuates based on who is supervising the site. The Maintenance Supervisor is often the most critical link in the safety chain, yet they are frequently the most overlooked.

The risk of liability spikes on weekends when Safety Officers are typically off-site. In these windows, supervisors often call in contractors directly to handle "emergency" repairs. If a supervisor skips compliance checks to save time, they aren't just starting a repair—they are buying a lawsuit.

To protect the company, every supervisor must use what I call The Supervisor's Shield—a pre-start checklist that must be satisfied before the contractor is allowed to offload a single tool:

The Supervisor's Shield: Pre-Start Checklist

  • Job Specification: Have they agreed to your site rules, PPE requirements, and procedures?
  • Section 37(2) Agreement: Is it signed and in the Safety File?
  • COIDA / Letter of Good Standing: Is it current and verified?
  • Public Liability Insurance: Do they have a certificate meeting your minimum (e.g., R5 Million) cover?

Expertise Without Compliance is Dangerous

Subcontractors bring necessary skills, but they also bring inherent risks. These risks must be managed through the Safety File before the job starts—not after.

A strict "No certificate, no work" policy is not a sign of a difficult client; it is the hallmark of a protected business. Managing risk with paperwork—specifically Section 37(2), COIDA, and Public Liability Insurance—ensures that a subcontractor’s mistake remains their responsibility and doesn't become your company's ruin.

If an emergency repair was needed this Sunday, would your current hiring process survive a R2 Million fire or a serious site injury?

Their accident should never become your liability.

The Skill No Safety Training Teaches (But Every Great Safety Officer Has)

Most Safety Officers are tolerated - not trusted. Where do you stand? Take this free quiz to uncover your credibility, leadership level, and what's holding you back. It's not your NEBOSH certificate. It's not your incident reporting skills. It's storytelling — and it might be the most powerful tool you're not using. Think back to your last toolbox talk or safety briefing. How many people were really listening? Not just nodding along. Actually  listening  — making eye contact, leaning in, taking it seriously. If that number is lower than you'd like, you're not alone. And the reason probably isn't your knowledge. You know the regulations. You know the risks. You've done the checklists. The problem is that  facts inform. Stories move people. And most safety officers were never taught how to tell a story. Why Data Alone Doesn't Change Behaviour Here's the thing: when you tell a crew that "87% of hand injuries happen in the first ...

Why Safety Officers Make Poor Decisions Under Pressure (And How to Improve)

  Learn why Safety Officers make poor decisions under pressure and how to improve judgement, leadership, and workplace safety using practical tools, scenarios, and checklist. Why Safety Officers Make Poor Decisions Under Pressure  Many workplace incidents are not caused by a lack of rules. They happen because someone made the wrong decision under pressure. Examples include: Ignoring a hazard to save time Continuing work without PPE Signing permits without checking controls Staying silent when unsafe behaviour is visible These are decision failures. Why This Happens 1. Production Pressure Deadlines and targets often push people to choose speed over safety. 2. Fear of Conflict Many safety professionals know the correct action but hesitate to challenge senior staff. 3. Unsafe Habits Become Normal If shortcuts happen often without consequences, people start believing they are safe. 4. Lack of Confidence Some Safety Officers understand compliance but struggle in real-time leadershi...

Safe by Design: Building Safety in Before the Risk Ever Shows Up

Why zero injuries doesn't mean zero risk. Learn the Safe by Design approach — plus download our free practical guide to get started.  Most workplace safety conversations start after something has already gone wrong — an incident report, a near miss, a machine that's injured someone. Safe by Design flips that script entirely. Instead of controlling hazards after equipment, processes, or workplaces are built, Safe by Design asks a simpler question upfront: can we design this hazard out before it ever exists? For OHS practitioners, employers, and training providers across South Africa, this shift matters. It moves safety from being a compliance afterthought to being a design decision — made at the drawing board, not the incident register. Free Guide: Safe by Design This post is the short version. Our free 10-page guide walks through the full lifecycle approach, the business case, and a practical implementation checklist you can start using this month. Download the free guide → Wh...
