Saudi heat stress prevention requirements are an important part of occupational safety and health management, particularly for workers performing outdoor activities during periods of high temperature.
Saudi authorities provide regulatory decisions and occupational safety guidance addressing exposure to direct sunlight and heat stress. HRSD has implemented a seasonal decision prohibiting work under direct sunlight during specified midday hours, supported by official procedural and advisory guidance.
This guide summarizes the current 2026 requirements and practical HSE controls. Seasonal dates should always be verified against the latest official announcement because they may change from year to year.
2026 Midday Work Ban
For 2026, the decision prohibiting work under direct sunlight applies from:
15 June 2026 to 15 September 2026
during the hours:
12:00 PM to 3:00 PM
The restriction applies to private-sector establishments and is intended to protect workers from direct exposure to the sun during the hottest part of the day.
Employers should organize work schedules accordingly and ensure that affected outdoor activities are planned to comply with the applicable decision.
Important: These dates are specifically for the 2026 season. They should not be presented as permanent dates for future years.
Employer Responsibilities
HRSD’s 2026 announcement emphasizes that employers have responsibilities related to preventing heat-stress risks.
Employers are expected to support worker protection by:
- Raising workers’ awareness of heat-stress risks and prevention.
- Monitoring workers’ physical condition during periods of high temperature.
- Ensuring workplace readiness for heat-related risks.
- Supporting the role of occupational safety and health personnel in monitoring compliance.
- Applying appropriate workplace inspection procedures and preventive measures before field activities begin.
Organizations should also follow the applicable official procedural and advisory guidance issued by Saudi authorities.
Practical Heat-Stress Controls
The official Saudi guidance provides information intended to help employers and workers prevent the effects of heat exposure and working in hot environments. NCOSH currently provides both a Procedural Guide for Preventing the Effects of Exposure to Direct Sun and Heat Stress and a Guidance Manual for Preventing the Effects of Working in Hot Environments.
In practical HSE management, employers should consider controls such as:
- Scheduling outdoor work to reduce heat exposure.
- Providing suitable shaded or cooled rest areas.
- Making drinking water readily available.
- Increasing worker awareness of heat-stress symptoms and prevention.
- Monitoring workers during high-temperature conditions.
- Considering workload, work duration, clothing and environmental conditions.
- Providing appropriate emergency arrangements.
- Supervising workers performing strenuous outdoor activities.
The exact control measures should be determined according to the workplace, activity, environmental conditions and applicable official guidance.
Recognizing Heat Stress
Heat stress can occur when the body is exposed to hot and humid conditions and cannot adequately control its temperature. The official Saudi procedural guidance identifies heat stress as a consequence of exposure to hot and humid weather and associated fluid loss.
HSE personnel and supervisors should ensure workers understand the importance of reporting symptoms or feeling unwell rather than continuing work when heat-related illness may be developing.
Any suspected serious heat-related illness should be treated as a medical emergency and managed according to the organization’s emergency arrangements and competent medical advice.
Practical HSE Compliance Approach
A practical approach to managing Saudi heat stress prevention requirements is:
Plan → Protect → Monitor → Respond → Review
1. Plan
Review weather conditions, work schedules, workforce requirements and heat-related hazards before starting outdoor activities.
2. Protect
Implement the applicable work restrictions and appropriate heat-exposure controls.
3. Monitor
Supervisors and HSE personnel should monitor working conditions and workers’ physical condition during periods of high heat.
4. Respond
Ensure workers know how to report symptoms and that appropriate emergency arrangements are available.
5. Review
Use inspections, observations and incidents to identify improvements to the heat-stress prevention program.
