Shipboard familiarization training for personnel onboard modern chemical tankers

It is essential on chemical tankers that everyone knows his ship's safety precautions thoroughly. Also the master/chief officer must assume responsibility for this. Newly signed on members of the crew should be familiarized about the following items and be shown around the ship to get detailed knowledge:

i ) Get to know pump rooms, cofferdams, pipe tunnels, emergency exits.

ii) The manouvering and emergency stops for cargo pumps and cargo valves.

iii) Bilging of pump rooms.

iv) Pump room ventilation incl information on necessary pre-ventilation before entry and emergency stop of fans in case of fire.

v) Safety showers-(in pump rooms, fore and aft on deck),

vi) Gas warning equipment incl the sounding of alarms (fixed and portable).

vii) Lifting gear incl stretcher to get an unconscious person out of a Pump room.

viii) Cargo tank vapour vents, incl opening, prior to cargo filling/discharge. ix) Cargo sounding equipment.

x) Location of fire fighting equipment incl detailed instructions for operating them.

xi) Portable fire (powder) extinguishers placed at hose manifold.

xii) Water hoses to be connected amidships ready for washing off cargo spills (if considered proper under the circumstances)

xiii) Cargo tank arrangement.

xiv) Cargo piping system incl means of segregation.

IMO codes guideline for modern chemical tankers
The IMO Codes address the safety of everyone involved and protection of the environment by ensuring that the ship will remain afloat after an assumed extent of damage, thereby minimising potential pollution and the uncontrolled release of cargo that could follow if a ship sank.

What is reactivity of noxious liquid chemicals while carrying at sea ?
The most common form of self-reaction is polymerisation. Polymerisation generally results in the conversion of gases or liquids into viscous liquids or solids. It may be a slow, natural process which only degrades the product without posing any safety hazards to the ship or the crew, or it may be a rapid, exothermic reaction evolving large amounts of heat and gases.

What is putrefaction process of liquid chemicals ?
Most animal and vegetable oils undergo decomposition over time, a natural process known as putrefaction (going off), that generates obnoxious and toxic vapours and depletes the oxygen in the tank. Tanks that have contained such products must be carefully ventilated and the atmosphere tested prior to tank entry .

Physical properties of various noxious liquid chemicals carried at sea
Specific Gravity (Density) ,Flash Point,Auto Ignition Temperature,Flammable / Explosive Limits,Vapour pressure/Boiling point,Freezing point/Melting Point....

It should be borne in mind that individual ship has got own characteristics and limitations may involved handling various chemical cargoes . The master and all personnel in all cases must be aware of cargo/ship information that has been given and comply with relevant safety procedures.
