Sound Shipboard Operating Procedures Answer - Procedural Compliance
Questioning Attitude
Forceful Backup
Formality
Level of Knowledge
Integrity
3 sides of compliance triangle Answer - time, workload, capacity
3 supporting processes of sound shipboard operating principles Answer -
ORM, PBED, Incident Reporting
ORM Answer - Accept risks when benefits outweigh costs
Accept no unnecessary risk
Anticipate and manage risks by planning
Make risk decisions at the right level
PBED Answer - Plan, Brief, Execute, Debrief
Incident Reporting Answer - Lessons learned to Fleet
,EXPLAIN why the electrical safety precautions are of increased importance
aboard a ship compared to ashore Answer - Ships are dangerous working
environments
Injuries caused by: equipment deficiencies, human failure, failure to follow
procedures
What instruction governs ELECTRICAL SAFETY? Answer - NSTM 300 Electric
Plant General
IDENTIFY the purpose and scope of the shipboard electrical safety program
Answer - 1. Standardized method for authorizing personal electronic
equipment onboard
2. All hands participation to properly disable and report any faulty equipment
up the chain of command
3. Encouraging reports of electrical shock incidents to medical for immediate
treatment and tracking
Ship board systems are grounded or ungrounded? Significance Answer - 1.
Ungrounded; Critical to reliability
2. Provide only a limited amount of current when one phase is faulted to
ground
3. Will always be some amount of current leakage so not perfectly ungrounded
Hazards associated with the shipboard ungrounded system Answer - If a
person is in contact with an energized conductor then shock, electricity follows
the path of least resistance which could be through the body.
Effects of electric shock on the human body Answer - Victim may be pale or
"bluish"
Breathing weak or entirely absent
, Cardiac arrest
Muscle, nerve, and tissue destruction
Thermal burns
The effects of current on the human body caused by electric shock with
numbers associated Answer - .001 = cause perceptible shock
.01 = loss of muscle control
.1 = causes ventricular fibrillation and can be fatal if applied to a vital organ for
more than one second(Our equipment is rated at 10-15 amps)
Electric Shock Rescue Answer - 1. Secure power immediately
2. Remove victim using non conductive object
3. CPR
CPR Requirements for Electrical Safety Answer - Minimum 50% of all
electrical/electronic ratings must be qualified with both the annual refresher
and the 2 year certification
CO Role: Electrical Safety Answer - Overall responsible for electrical safety and
authorizes all work on energized equipment. CDO's approval needed in CO
absence. Exemptions are in EDORM.
ELECTRO Role: Electrical Safety Answer - 1. Establishes tool issue and
authorizes electrical tools/equipment for shipboard use
2. Ensures CPR instructor certification is up-to-date
3. Supervises maintenance, repair and issue of Energized/de-energized
equipment, Portable electrical tools and PPE
4. All Energized work chits go through the ELECTRO
5. Must be Safety Programs Afloat qualified (ESO Qual)
