Occupational health and safety (OHS): meaning, roles and programmes
Occupational health and safety (OHS, also written OSH) is the set of rules, programmes and roles that protect workers from injury at work and from illness caused by it. This entry explains what the field covers, who works in a safety department, the core programmes it runs, the general framework in Saudi Arabia, and where camera-based monitoring helps a safety team and where it does not.

Meaning
What occupational health and safety covers
The field has two halves. Occupational safety deals with events that happen in a moment: a fall, a hand caught in a machine, a collision with moving plant, a fire. Occupational health deals with harm that builds up slowly: noise that damages hearing, dust and fumes, heat, chemicals, manual loads that injure the back over years, and work pressure.
The two halves need different tools. An injury is recorded on the day; an occupational disease may not show for years, so it needs periodic workplace measurement and medical checks that do not wait for harm to appear.
The scope is the workforce. When the environment is added to the same responsibility, the usual name becomes HSE (health, safety and environment) on field sites, or EHS at company level.
Programmes
The core programmes of an OHS management system
| Programme | The question it answers | The record it leaves |
|---|---|---|
| Risk assessment | What could harm workers, how badly, and which control fits | The risk register and the control plan |
| Permit to work (PTW) | Is this high-risk job ready to start, and who owns it | The signed permit and the time it was closed |
| Lockout tagout (LOTO) | Is energy isolated before maintenance | The lock and tag log and the zero-energy check |
| Personal protective equipment (PPE) | What each area requires, and whether it is worn | The PPE matrix, issue records and inspections |
| Incident and near-miss reporting | What happened or nearly happened, and why | The report, investigation and corrective action |
| Emergency plan | What each person does in an incident | The plan and the drill records |
| Training and toolbox talks | Does the worker know today's hazard | Attendance and topic |
| Performance indicators | Is the site improving or slipping | Periodic leading and lagging indicators |
Not every site needs every programme at the same depth. A workshop and a refinery do not share hazards; the risk assessment decides which programmes are needed, and how far.
Roles
The safety department and its staff: who does what
- Safety manager or HSE manager: owns the system, sets policy and targets, and reports to senior management.
- Safety engineer or specialist: writes procedures, leads risk assessments and HAZOP studies with operations, and investigates incidents.
- Site safety supervisor: in the field daily; checks permits, follows PPE compliance and often holds stop-work authority.
- Occupational health: a doctor or nurse who runs pre-employment and periodic checks and follows exposure to noise, dust and heat, on staff or contracted.
- Safety committee and worker representatives: where workers raise what they see and follow findings to closure.
Headcount and qualifications vary with the site's size, activity and what authorities and clients require. What matters is written responsibility: every programme has an owner, every finding a person and a date.
In practice
Finding hazards and controlling high-risk work
Finding and rating hazards
Everything starts with risk assessment, and a risk matrix ranks hazards by likelihood and severity. For a single task there is the job safety analysis (JSA); for process units, a HAZOP study.
High-risk work
A permit to work controls when dangerous work starts and who signs for it, and lockout tagout (LOTO) makes sure energy is isolated before maintenance. Confined spaces and work at height each carry their own controls.

In practice
Everyday prevention, reporting and measurement
Everyday prevention
PPE is the last line in the hierarchy of controls, not the first; a toolbox talk reminds the shift of the day's hazard; and the emergency plan sets what each person does when an incident happens.
Reporting and measurement
Read more
Reporting a near miss exposes the weakness before anyone is hurt, and classifying work injuries keeps recording consistent. From those records come lagging indicators such as lost-time injuries (LTI) and the total recordable incident rate (TRIR), balanced by leading safety KPIs.

In a Saudi context
Occupational safety in Saudi Arabia
In the Kingdom, the Ministry of Human Resources and Social Development regulates the workplace and its safety requirements, and the National Council for Occupational Safety and Health coordinates national policy across the bodies involved. Sector regulators in energy, industry and construction add requirements, and large clients add theirs through contractor contracts.
What applies to a given site comes from the official source and its clients' requirements, not from a summary like this. The recurring practical question is different: how a small safety team sees a site with several contractors, a multilingual workforce and long shifts in summer heat.
Interkey's team works from Riyadh with Arabic-speaking engineers, and recordings can stay on the site's own servers in the Kingdom when the platform runs on premises.
The product connection
How camera-based monitoring supports the safety team
Most industrial sites have CCTV that records all day and is watched only after an incident. SquintPRO is video analytics that works on those existing cameras over RTSP/ONVIF and watches for defined situations, such as missing PPE in an area that requires it, entry to a restricted zone, or pedestrians near forklifts, and sends the supervisor an alert with a snapshot.

It is licensed per camera stream, with unlimited use cases on a licensed stream, so a new use case can be added on the same camera without another licence. It runs on the site's own servers, or in the cloud with a recording retention of 3, 6 or 12 months.
Its limits are clear: it does not replace the supervisor or the permit to work, measure noise or dust exposure, or recognise faces. It gives the team eyes on areas it cannot reach and a record for leading indicators. The usual first step is a scoped pilot on the site's cameras.
FAQ
Questions safety teams ask
Short answers to what people most often ask about occupational health and safety.
What is the difference between occupational safety and occupational health?
Safety prevents sudden events such as falls, entanglement and fire. Health prevents harm that builds up, such as hearing loss from noise and lung disease from dust. One system manages both.
What does a safety department do in a company?
It writes procedures, assesses risks, checks permits, follows field compliance, trains workers, investigates incidents and reports indicators to management, and with occupational health follows periodic medical checks.
Which authority is responsible for occupational safety and health in Saudi Arabia?
The Ministry of Human Resources and Social Development regulates workplace safety requirements, and the National Council for Occupational Safety and Health coordinates national policy. Sector regulators and large clients may add requirements.
Does every company in the Kingdom need a full-time safety officer?
It depends on the size of the site, its activity and what authorities and client contracts require. A small business may assign it alongside other work; a high-risk site usually needs a dedicated team. Check the official source, not habit.
Where do you start when building an OHS system for a new site?
With the risk assessment: list the tasks, places and materials that could harm workers, then choose controls from removing the hazard down to PPE. Then write roles, permits and the emergency plan, and pick a few indicators to review monthly.
How long does a SquintPRO pilot on site cameras take, and do recordings stay in the Kingdom?
A pilot usually runs for weeks; the duration is an estimate driven by camera count, image quality, network access and use cases. On the site's own servers, recordings stay on site in the Kingdom.
