COSWP (Enclosed space entry, WAH, Other checklists) Flashcards
MGN 659:
Guidance on Entry into Enclosed space regulations 2022
Oxygen level for safe entry:
20.8%
Any less and we would be testing for gases that may displace this oxygen
Any more could be explosive particularly after 25%
What Gases do we test for?
Done with atmosphere testing equipment
Oxygen (O2 meter)
Toxic Gases (Hydrogen Sulphide and Carbon Monoxide) (Multigas meter)
Flammable Gases (Explosimeter)
How frequently are we to conduct enclosed space entry drills?
At least once every 2 months
MGN 410
MS and Fishing vessels (health and safety at work) (Work at Height) Regulations 2010
Personnel working at heights should:
Wear a safety harness with a lifeline or other arresting device at all times
Define West country method and procedure
A technique for stopping knots when mooring
Half knot is tied around the mooring line
Two ends of stopper line are wrapped around the mooring line, alternately passing ovr and under each other
After several turns are made, the ends are secured with a square knot
Snapback zones
Areas where mooring lines may recoil dangerously if they break under tension
What is an enclosed space?
A space not designed for continuous worker occupation, and that has at least one of the two following characteristics:
Inadequate ventilation
Limited openings for entry and exit
Examples of Enclosed Spaces
Fuel tanks
Double bottoms
Coffer dams
Chain lockers
Sewage tanks
Void spaces
Cargo pump rooms
CO2 rooms
Battery Lockers
A register should be made of any enclosed spaces that seafarers may enter. This shall include:
Characteristics of the space for use in an emergency situation/entering situation
Any potential hazards
Measures to prevent entry (locking and signage)
Procedures to follow when entering
Information relating to ventilation, Including equipment and its storage location
Lighting requirements for temporary lighting
Requirements for atmospheric testing
Procedure for entering an enclosed space
Review of register of enclosed space/Inform Master of proposed procedure
Conduct Risk Assessment

If we have a near casualty (incident), what should we do?
Report this to the MAIB, so as to ensure future safety for seafarers and avoid possible future occurances
MGN 564:
Guidance on reporting incidents and casualties to the MAIB
What is the MAIB
Marine Accident Investigation Branch
MGN 410:

What defines WAH?
Working anywhere where there is a RISK of falling
When do we conduct working at height procedures?
Only when there is no other safe alternative for completing the works to be carried out
MGN 578
Use of Overside Working Systems on Commercial yachts, small commercial vessels and loadline vessels
What formula decides the scope of the anchor chain to be laid out?
1.5 x √Depth in meters
Where do we find information on Enclosed Space Entry?
