Construction requirements
Oman construction projects require a project-specific HSE Plan covering risk assessment, emergency response, training, and incident reporting. Muscat Municipality publishes prescriptive technical guidelines for excavation, scaffolding, demolition, crane operations, formwork, working at height, and temporary structures — with site inspections by the DM Building Inspection Section. Ministerial Decision 286/2008 includes technical standards for machinery safety, chemical handling, electrical safety, and working at height. PDO Life Saving Rules are mandatory for all PDO contractors — covering working at height, confined space, PTW, isolation/LOTO, and hot work.
Worker welfare
Mandatory midday ban on outdoor work under direct sunlight, 12:30–15:30 from 1 June to 31 August each year (Article 16 of Ministerial Decision No. 286/2008, as amended; discretionary exemptions under Ministerial Decision 322/2011 for employers who provide air-conditioned shade, cold drinking and washing water, first aid and air-conditioned transport). Employers must provide shaded rest areas, drinking water, cooling facilities, and acclimatisation programmes for new workers. Maximum 45-hour workweek (9 hours/day). Social Protection Law RD 52/2023 enhances worker welfare provisions. PDO Contractor Welfare Procedure sets accommodation and welfare standards for PDO contractor camps.
Penalties and enforcement
Fines of RO 500–1,000 for midday-ban violations (Ministry of Labour enforcement of the June–August outdoor work ban). Other penalty amounts were not verified against an official source, so confirm every fine with the Ministry of Labour or the official text of the relevant decision before relying on it.
