One of the most common questions we receive from employers is whether South African law sets a single, fixed blood-alcohol limit for the workplace, similar to the 0,05 grams per 100 millilitres rule that applies on the roads. The short answer is that it does not. There is no nationwide statutory BAC threshold that applies automatically to every factory floor, mine, warehouse, or office.
Instead, the law places the responsibility for setting and enforcing an alcohol limit on the employer itself, through a written workplace policy. What the statutes do is create the framework: a duty to keep the workplace safe, a duty to act fairly, and a duty not to discriminate. The actual number is set by the employer, within that framework, and it must be defensible if it is ever tested at the CCMA or in the Labour Court.
This article sets out, in practical terms, how an employer lawfully sets a workplace alcohol limit, how testing may be carried out, and the special treatment that applies to safety-critical roles. It is written for business owners, human resources managers, and fleet operators who need to align policy with South African labour and occupational-safety law.
There Is No Single Statutory Workplace Limit
The Occupational Health and Safety Act 85 of 1993 (OHSA) does not prescribe a blood-alcohol number for the workplace. What it does, in section 8, is place a general duty on every employer to provide and maintain a working environment that is safe and without risk to the health of employees. Section 14 then places a reciprocal duty on employees not to endanger themselves or others, which includes reporting for duty in a fit state.
The Labour Relations Act 66 of 1995 (LRA) governs how an employer may respond when an employee breaches an alcohol rule. Dismissal for being under the influence at work is recognised as a fair reason, but only if the procedure followed is fair and the rule itself was reasonable, known to the employee, and consistently applied.
The Employment Equity Act 55 of 1998 (EEA) adds a further layer. Medical and psychological testing of employees is regulated under section 7, and such testing is only lawful where it is justifiable in the light of the medical facts, employment law, and the inherent requirements of the job. Alcohol testing falls squarely within this section, which is why the policy behind the testing matters as much as the testing itself.
How Employers Lawfully Set a Workplace Limit
Because the law does not hand the employer a fixed number, the limit is set through the employer’s own alcohol and substance-abuse policy. For most office-based roles, a zero-alcohol standard during working hours is common and easy to justify. For safety-sensitive roles, the policy often sets an explicit BAC threshold, and many employers borrow the road-traffic figures as a reference point.
A typical South African industrial policy will set a pre-shift and random-testing limit of 0,00 grams per 100 millilitres of blood for operators of machinery, drivers of company vehicles, and employees working at heights, in confined spaces, or with hazardous chemicals. The lower 0,02 grams per 100 millilitres limit that applies to professional drivers under section 65 of the National Road Traffic Act 93 of 1996 is often used as the outer boundary for any employee who drives on duty.
For the policy to be enforceable it must be in writing, it must be brought to the attention of every employee, and it must form part of the contract of employment or the disciplinary code. A limit that employees do not know about, or that sits only in a manager’s drawer, will not survive a fairness challenge at the CCMA.
- Write the limit down. The policy must specify the threshold, the roles it applies to, and the testing method.
- Link the limit to the job. Different thresholds for office staff and safety-critical staff must be justified by the inherent requirements of each role.
- Communicate the policy. Every employee must sign acknowledgment of the policy, preferably on appointment and again on each revision.
- Apply it consistently. Selective enforcement opens the employer to discrimination claims under the EEA.
The Safety-Critical Roles Angle
Courts and arbitrators accept that some roles carry a higher risk and warrant a stricter limit. The concept is not invented by the employer; it is recognised in the schedule to the National Code of Practice for the Construction Industry, the Mine Health and Safety Act 29 of 1996, and the dangerous-goods provisions of the National Road Traffic Regulations. An employee who operates a crane, drives a heavy goods vehicle, or works on a live production line can lawfully be held to a near-zero threshold, while a clerk in the same business cannot be tested to the same intensity without a comparable justification.
The trigger is the inherent requirement of the job. Where sobriety is genuinely inherent to the role, a zero limit, mandatory pre-shift testing, and post-incident testing are all defensible. Where it is not, the employer must work harder to show why the testing is justifiable, and may have to rely on reasonable suspicion rather than random testing.
- Drivers of company or reward vehicles. Bound by the lower professional-driver limit where applicable, and usually by a zero workplace limit on top.
- Operators of machinery and plant. Cranes, forklifts, presses, and production-line equipment justify a zero threshold.
- Working at heights and in confined spaces. Construction, mining, and chemical-handling roles carry a heightened risk that supports strict testing.
- Healthcare and childcare workers. A zero standard is common and defensible on patient-safety grounds.
Conducting Alcohol Testing Lawfully
Under section 7 of the EEA, testing of an employee is only permitted where it is justifiable in the light of the medical facts and the inherent requirements of the job. In practice this means that the employer must be able to show that the testing method is reliable, that the reason for testing is linked to safety, and that the employee’s right to privacy and bodily integrity has been respected.
The generally accepted approach in South African workplaces is a two-stage process. A preliminary breath-alcohol screen using a properly calibrated breathalyzer is used to identify a possible positive. A confirmed positive is then followed by an evidential breath or blood test, conducted by a qualified person, before any disciplinary action is taken. This two-stage approach reduces the risk of a false positive becoming the sole basis for dismissal.
- Use certified equipment. Breathalyzers must be calibrated and serviced on the manufacturer’s schedule, and records kept.
- Train the testers. The person operating the device must be competent; CCMA arbitrators regularly question untrained testers.
- Confirm the result. A second, evidential test protects both the employer and the employee against false readings.
- Maintain confidentiality. Results are medical information and must be handled under the Protection of Personal Information Act 4 of 2013.
Discipline, Dismissal, and the Incapacity Alternative
A positive test is not, on its own, the end of the employment relationship. The LRA and the Code of Good Practice: Dismissal require the employer to consider the nature of the offence, the employee’s record, and whether the conduct amounts to misconduct or to incapacity. A single positive on a random test for an otherwise unblemished employee in a non-safety-critical role may warrant a written warning and referral to an employee assistance programme, while a crane operator who reports for duty over the limit may face dismissal on a first offence.
Where alcohol use amounts to a dependency, the correct route is usually incapacity, not misconduct. Schedule 8 of the LRA requires the employer to investigate the extent of the incapacity, consider whether it is permanent or temporary, and look at ways to accommodate the employee, including counselling and rehabilitation, before resorting to dismissal. Failing to follow this route is one of the most common reasons employers lose alcohol-related matters at arbitration.
Consequences of Getting the Policy Wrong
An employer that operates without a written alcohol policy, or that applies one inconsistently, exposes the business to three distinct risks. The first is an unfair dismissal or unfair labour practice finding at the CCMA, which can carry compensation or reinstatement orders. The second is liability under OHSA where an alcohol-related incident injures an employee or a third party and the inspectorate finds that no policy was in place. The third is a discrimination claim under the EEA where testing is applied selectively to a protected group.
Each of these is avoidable with a properly drafted policy, a defensible testing protocol, and a disciplinary code that tracks the LRA and its Codes of Good Practice. The cost of getting the framework right at the outset is a fraction of the cost of defending a single CCMA referral.
Frequently Asked Questions
Is there a legal blood-alcohol limit for the workplace in South Africa?
No. There is no single statutory blood-alcohol limit that applies to every workplace. The Occupational Health and Safety Act 85 of 1993 places a general duty on the employer to keep the workplace safe, and the employer sets the actual limit through a written alcohol policy that must be fair, communicated, and consistently applied under the Labour Relations Act 66 of 1995.
Can an employer set a zero-alcohol limit for safety-critical roles?
Yes. Where sobriety is an inherent requirement of the job, for example for drivers of company vehicles, operators of machinery, or employees working at heights or with hazardous substances, a zero or near-zero limit is defensible. The limit must be written into the policy, communicated to employees, and supported by a lawful testing protocol.
Is workplace alcohol testing legal in South Africa?
Yes, provided it is justifiable under section 7 of the Employment Equity Act 55 of 1998. The testing must be linked to the inherent requirements of the job, use certified equipment operated by trained personnel, and respect the employee’s right to privacy. A two-stage process of screening followed by an evidential confirmation is the accepted approach.
Can an employee be dismissed for being under the influence at work?
Yes, but only if the rule was reasonable, known to the employee, and a fair procedure was followed under the Labour Relations Act 66 of 1995. For safety-critical roles dismissal on a first offence may be fair, while in other cases the employer may be required to treat the conduct as incapacity and consider counselling or rehabilitation before dismissal.
What laws govern alcohol in the South African workplace?
The four main statutes are the Occupational Health and Safety Act 85 of 1993, the Labour Relations Act 66 of 1995, the Employment Equity Act 55 of 1998, and the National Road Traffic Act 93 of 1996 for employees who drive on duty. The Protection of Personal Information Act 4 of 2013 also applies to the handling of test results.
