• Currents: Musandam pinnacles and headlands can run strong. Stay close to your guide, agree on separation procedures, and carry an SMB on every dive.
• Boat-based profiles: Many sites are reached by boat, so practice controlled entries and ascents and keep situational awareness for traffic when surfacing.
• Depth and no-deco discipline: Typical recreational depths run 6 m to 30 m, but walls and pinnacles can tempt deeper drops. Dive within your training and plan conservative margins if visibility is low.
• Seasonal sea state: Dhofar's Khareef season can bring more swell and reduced clarity. If conditions look marginal, switch to sheltered sites or skip the water day.

For emergencies, use the national emergency number and follow the instructions of local authorities. For dive injuries, your operator will usually coordinate the first response and transfer options.

• Emergency access is best in major cities (Muscat and Salalah). Remote regions and offshore islands can require longer transfers or evacuation, so do not dive without appropriate insurance.
• Carry your insurance details and any DAN membership information in a waterproof pouch, plus your operator's local contact numbers.
• Heat and dehydration are common trip-ruiners in summer. Hydrate and manage sun exposure as part of dive safety.

Oman has an active marine conservation framework led by the Environment Authority, including marine reserves, permit systems, and wildlife protection rules.

• Daymaniyat Islands Nature Reserve: no coral or marine-species collection, no disturbing turtles or eggs, and carry out all trash. Seasonal access restrictions apply under reserve management rules.
• Hallaniyat Islands: a maritime buffer reserve has been established around the archipelago. Treat it as a high-sensitivity area and confirm current access rules with your operator.
• Wildlife ethics: keep distance from whale sharks, turtles, and dolphins, avoid flash photography on turtle beaches, and never feed fish.

Small actions help: reef-safe sunscreen, refillable water bottles, and choosing operators that use moorings and brief reef etiquette.
