Study Notes

Hot Work

Marine Chemist must inspect and sign a sheet daily after hot work.
Competent person must reinspect if the sheet is not signed
Contractor must prepare a hot work chit and notify EOW 24 hours in advance.
Chit needs the signature of the EOW and CO if in a confined space
Hot work must be conducted in a 13-man duty section.
Outside the shop, the following need to sign off on the hot work chit: EOW, OOD, GFE, EO
GFE's: LTJG Bragaw, LTJG Phillips
Fire watch required with water extinguisher, radio, goggles.
Fire watch needs to remain on duty for 30 minutes after work finishes (or until cooled).
Fire watches are needed on both sides of the boundary during hot work on bulkheads or decks.
Hot work chits are posted at each entrance.
If there is an IDLH (Immediately Dangerous to Life or Health), CO must sign.
Hot work stops when there is no fire watch.
Contractor welding becomes fire watch until another person takes over.

Power Outages

Ensure STBY Gen kicks on.
Confirm the system is intact.

Reset fire alarm panel
Address vital Fans, non-vital fans, VCHT, and HF rooms.
Check Graywater, hot water pumps, and boat retrieval panels.
Verify breakers on SWBD.
Notify EO once everything is done.

Safety Standards

Rounds at 1000, 1400, 1800, and 2200 (or as needed).
Secure all engineering spaces.
Follow lighting off schedule and steaming orders.

Man Aloft

Notify EO if going aloft.
Zones 1-5 have different requirements for personal fall arrest safety equipment.
Zone 1 (Top of Bridge) - no PFAS required unless going over the edge, on the doghouse.
Zone 2 (Lower Two Yardarms) - PFAS not needed unless going over the edge.
Zone 3 (Upper Mast) or Zone 5 (Front of Bridge) - working outside the mast requires PFAS.
Zone 4 (Top of Stackhouse) - restricted, PFAS required if near platform edge.

Divers Down

Coordination with divers is required the day before tasks to be performed.
Preparation of a Diving Safety Checklist and Briefing.
The Briefing must include Emergency Plan and Communications overview and Environmental Conditions.
Tag out sections

Toxic Gas

Confined spaces are deemed IDLH when oxygen content is less than 19.5% or more than 22%.
Flammable vapors must have concentrations of 10% or more of the lower explosive limit.
Toxicants must be below safe limits per National Institute for Occupational Safety and Health standards.
Sprinklers and APC systems must not be compromised if toxic gas leak.

Parasense 3300

Refrigerant Monitors are installed in A/C and Reefer Flats (4 in A/C, 2 in Reefer).

Report to EO if the flooding cannot be contained.
CO permission should be sought before dewatering.

Fire

The Rapid Response takes initial actions (Securing, machinery, fuel/lubricant valves, extinguishers, etc.).
Identify issues if the fire is out of control (Activate installed systems, 440V and ventilation, set boundaries, man up the furthest repair locker, and call fire fighters).
Ensure two fire teams enter the space.

Fire Department

When the Fire Department is involved, prioritize safe procedures and secure ventilation.
JEOW should assist with escorting the Fire department and securing appropriate water lines.
Communicate with Fire Dept with cognizance over the ship.
