Occupational Health Standards — Basic Structure

Basic Structure

Organise the problem by function

Start with the hazard and the task that creates exposure. Identify the people affected, including workers whose contract status or maintenance duties might leave them outside a narrow staffing list. Then examine exposure conditions, possible consequences and existing controls. A register naming a hazard is a starting record, not a completed risk assessment.

Control selection should address the source and pathway where feasible. Elimination, substitution and engineering measures can reduce dependence on repeated individual action. Administrative arrangements and personal protection may complement these measures. Count verified performance, not simply the purchase of equipment or attendance at a briefing.

Connect measurement to a decision

An exposure result needs its unit, method, sampling duration and relevant comparison standard. A health-surveillance result needs competent interpretation and an appropriate follow-up route. These two forms of evidence are related but distinct: a normal examination does not demonstrate that the source has been controlled, and a measured hazard is not itself a diagnosis.

Separate duties from guidance

The OSH Code, its commencement instrument and applicable rules have different legal roles. Section 18 concerns standards; section 6 includes employer obligations. The final Central Rules notified in May 2026 must be read within their jurisdiction. ILO and NIOSH material offers technical guidance and cannot by itself settle which Indian rule applies. Review the assessment when tasks, materials or evidence change, with responsibility and completion dates clearly recorded.
