~> A copy to be kept in crew mess OR in each crew accommodation.
When should Drills be done?
(7)
Drills should be treated as if it were an actual emergency
• If passengers will be onboard for 24hrs+ : Muster & lifejackets
• New passengers : Safety briefing
• Fire / Abandon ship: Every month
• If more them 25% of crew has not done Fire / A.S drill within 24hrs of leaving port
• Ship enters service for first time / major modifications / major character joins : Drill before leaving port
• Enclosed space drill every 2 months
HRU
Validity?
Explain how it works along with how it would be attached to a liferaft.
2 year validity.
Submerged to 1.5m - 4m diaphragm compresses, releasing spring, cutting strong rope, releasing liferaft and allowing the liferaft to float free.
The strong rope attaches the STENHOUSE SLIP to the HRU
~> (hence when cut the liferaft can float free)
The painter is attached to the top of the weak link
~> (when the liferaft inflates the buoyancy vs the sinking ship will break the weak link allowing the liferaft to float free)
The bottom of the weak link is attached to a strongpoint on the ship.
