SAFETY SUMMARY

GENERAL SAFETY NOTICES.

The following general safety notices supplement specific warnings and cautions appearing elsewhere in this manual. General and specific precautions must be understood and applied during operation and maintenance of systems and equipment covered herein. The Commanding officer or other authority will issue orders necessary for any situations not covered in these general and specific safety precautions.

DO NOT REPAIR OR ADJUST ALONE.

Under no circumstances should repair or adjustment of energized equipment be attempted alone.

The immediate presence of someone capable of rendering aid is required. Before making adjustments, be sure to protect against grounding. If possible, adjustments should be made with one hand, with the other hand free and clear of equipment. Even when power has been removed from equipment circuits, dangerous potentials may still exist due to retention of charges by capacitors. Circuits must be grounded and all capacitors discharged prior to attempting repairs.

TEST EQUIPMENT.

Make certain test equipment is in good condition. If a test meter must be held, ground the case of the meter before starting measurement. Do not touch live equipment or personnel working on live equipment while holding a test meter. Some types of measuring devices should not be grounded; these devices should not be held when taking measurements.

MOVING EQUIPMENT.

If equipment must be repaired/adjusted while in motion, a safety watch is posted. The safety watch must have a full view of the repair/adjustment operation and immediate access to controls that can stop the equipment in motion.

FIRST AID.

An injury, no matter how slight, should never go unattended. Always obtain first aid or medical attention immediately.

RESUSCITATION.

Personnel working with or near high voltage is familiar with approved resuscitation methods. If someone is injured and stops breathing, initiate resuscitation immediately. A delay could cost the victim’s life.

GENERAL PRECAUTIONS.

The following general precautions are to be observed at all times:

1. All electrical components associated with system/equipment is installed and grounded in accordance with applicable Navy regulations and approved shipboard practices.

2. All maintenance operations comply with Navy Safety Precautions for Forces Afloat, OPNAVINST 5100 series.

3. Proper installation and maintenance of protective guards and shutdown devices around rotating parts of machinery and high voltage sources is observed.

4. Special precautionary measures are essential to prevent applying power to systems equipment at any time maintenance work is in progress.

5. Do not make any unauthorized alterations to systems/equipment.

6. Before working on electrical systems/equipment, use voltmeter to ensure that system is not energized.

7. All circuits not known to be DEAD must be considered LIVE and dangerous at all times.

8. Do not wear loose clothing while working around rotating parts of machinery.

9. When working near electricity, do not use metal rules, flashlights, metallic pencils or any other objects having exposed conducting material.

10. Be sure to de-energize all equipment before connecting or disconnecting meters or test leads.

11. When connecting a meter to terminals for measurement, use range higher than expected voltage.

12. Before operating equipment or performing any tests or measurements, ensure that frames of all motors and starter panels are securely grounded.

13. Ensure that areas are well-ventilated when using cleaning solvent. Avoid prolonged breathing of fumes and solvent contact with skin or eyes.

14. Before entering voids and tanks, make sure that they have been properly ventilated and all gas freed.

WARNINGS AND CAUTIONS.

Specific warnings and cautions covered by this manual, and corresponding systems manuals, are summarized below for emphasis.

WARNING

When the FM 200 system discharge warning alarm sounds, all personnel should immediately evacuate the space. FM 200 discharged is hazardous to an individual’s health.

WARNING

Before taking on fuel, ensure safeguards and firefighting equipment are ready. Immediately clean all spills.

WARNING

Hydrogen gas is present and explosive around batteries. Ensure no sparks or open flames are near batteries.

WARNING

Hydrogen sulfide gas can cause unconsciousness and death. If a space is suspected of containing hydrogen sulfide, it should be thoroughly ventilated and personnel entering the space will wear self-contained breathing apparatus.

WARNING

Personnel with duty of servicing refrigeration systems using halocarbon compounds (freon) shall wear safety goggles to eliminate the possibility of the liquid refrigerant coming in contact with the eyes and causing injury due to the freezing effects of the liquid.

WARNING

For HVAC, liquid and gas under pressure, overheating and over pressurizing may cause gas release or violent cylinder bursting. May decompose on contact with flames or extremely hot metal surfaces to produce toxic and corrosive products. Vapor reduces oxygen available for breathing and is heavier than air. Harmful if inhaled and may cause heart irregularities, unconsciousness or death. Liquid contact with eyes or skin may cause frostbite.

WARNING

When working with the UV filter, DO NOT LOOK AT THE UV LIGHT!!!

WARNING

Working with R-401A requires that you use tools, pumps and recovery equipment and tanks rated for the higher pressure.

WARNING

The searchlight becomes hot with prolonged use. Do not touch it.

WARNING

Open shore side circuit breaker or disconnect switch before disconnecting incoming power leads. Live power leads could cause electrical shock to personnel.

WARNING

Prior to emergency stopping, inform crew to stow loose gear and position themselves as required. Unless precautions are taken, this procedure may cause injuries.

WARNING

Stop propulsion engine and tag out starter controls before locking shaft to prevent injury to personnel caused by rotating machinery.

WARNING

The fuel oil capacity exceeds the endurance requirements for the vessel. DO NOT OVERLOAD the vessel. Please follow the stability booklet attached as Appendix C.

WARNING

Use insulated tools and test equipment when working on electrical components. To prevent hazards to personnel, ensure equipment is de-energized and tagged out of service.

CAUTION

To prevent damage to ship-service generator starer winding, verify generator circuit breaker is open before attempting to start diesel.

CAUTION

When working with the refrigerant Genetron AZ-20 R-410A for commercial air conditioning, tools, pumps and recovery equipment and tanks rated for higher pressure are required.

CAUTION

When working with the UV system, rapid successive cycling of the power to the ballasts can cause premature failure of the system components.

CAUTION

For HVAC, do not turn off fan until all heat is fully dissipated from heater. If switch is turned off during heating cycle, auto and manual hi-limits may open due to the excessive heat build-up.

CAUTION

To prevent damage to starter, when engine does not start, do not depress START switch while starter motor is running down.

CAUTION

Do not use crane without studying crane safety and vessel stability impact. Improper crane usage in a seaway can pose a safety hazard.

CAUTION

Do not reverse craft using full throttle. The sudden and fast reverse movement of the craft can make the ramp serve as a large water scoop and fill the ramp up the main deck. This can be a safety hazard.

CAUTION

Do not crank engine more than 20 seconds at a time when using an electric starting motor.

Allow 3 minutes between starting attempts so starting motor will cool down and not become damaged through overheating.

CAUTION

If the power supply fails, the transmission automatically shifts to neutral. This can cause the vessel to become un-maneuverable.

CAUTION

Please see the safety section of the Caterpillar Operation and Maintenance Manual to ensure safe engine operation.

CAUTION

Always reduce engine speed to idle when reversing propeller rotation to avoid damage to the marine gear and propulsion shafting.

CAUTION

Hydraulic steerage pumps have suction shutoff valves. Even short term operation with valve closed can cause pump damage.

CAUTION

Rapid shifting at high engine speeds can damage the marine gear.

CAUTION

Serious damage may occur to the bilge pumps if they are operated in a dry condition. Ensure bilge pump priming line valve is open.

CAUTION

To protect electronic circuits, the 24 V and 12 V battery systems should be set to OFF during loss or transfer of ship’s power. Damage to electronic circuits can result from voltage spike.

CAUTION

Use of the emergency air shutdown system can cause oil to be drawn past the propulsion engine oil seals and into the blower housing.

CAUTION

Do not operate fire main pumping unit without suction valve open, permitting liquid in the pump volute. Without cooling liquid, pump will rapidly overheat.

CAUTION

Ensure sufficient time has elapsed before re-energizing engine room fans, to allow fire to be completely extinguished and space to cool. This will eliminate the possibility of flash back.

CAUTION

Side blocks must be tied at the top and bottom to keel blocking. This prevents side blocks from shifting and causing damage to the hull.

CAUTION

If full throttle is used while towing another vessel, watch for signs of overheating of the main propulsion engines. Reduce engine RPM, if necessary, to prevent main engine damage.
