Results for "Risk assessment"
What is a risk assessment on a ship and how is it done?
A shipboard risk assessment systematically identifies the hazards of a task, evaluates the risk and puts controls in place before the work begins.
Shipboard OperationsWhat is a toolbox talk and when is it done?
What a toolbox talk is, when it happens before shipboard work, and how it turns the risk assessment and permit into a shared plan.
Shipboard OperationsWhat must be checked before enclosed space entry?
The core precautions before entering an enclosed space — atmosphere testing, permit, ventilation, standby and communications — because these spaces still kill seafarers.
Shipboard OperationsWhat is a permit to work (PTW) system on ships?
A permit to work is a formal written authorisation that controls hazardous, non-routine jobs by confirming the hazards are assessed and the right precautions are in place.
Shipboard OperationsWhat is a snap-back zone and why is mooring so dangerous?
A snap-back zone is the area a mooring line may whip through if it parts under tension — mooring decks are among the most dangerous places on a ship.
Shipboard OperationsWhy are enclosed spaces on ships so dangerous?
Enclosed spaces kill because their atmosphere can be oxygen-deficient, toxic or flammable with no outward sign — and rescuers who rush in become the next victims.
Shipboard OperationsWhat is a Safety Management System (SMS) on a ship?
A Safety Management System is the documented set of policies and procedures, required by the ISM Code, by which a company manages the safe operation of its ships and prevention of pollution.
Shipboard OperationsWhat is a near miss on a ship and why is reporting it important?
A near miss is an event that could have caused injury, damage or pollution but happened not to — reporting them lets a ship correct hazards before they cause a real accident.
Shipboard OperationsWhat is lock-out tag-out (LOTO) and why is it used aboard ship?
Lock-out tag-out is the practice of isolating a machine's energy sources and physically locking and tagging them off before maintenance, so it cannot be started or energised while someone is working on it.
Shipboard OperationsWhat safety precautions are taken for working aloft on a ship?
Working aloft — up the mast, funnel or high structures — demands a permit, a safety harness, secured tools, and control of hazards such as radar, whistle and overside work.
