2.1 Identify the chemicals used on board
the ship based on their general
classification.
Fuel additives, cooling towers,
electric motor cleaners, biological
cleaners, boiler water and evaporator
chemicals, seaweed inhibitors, tank,
carbon, acid, cement cleaners, cooling
water and sea water chemicals are
world-class products used in the
required areas.
Segregate chemicals by hazard class (flammable compressed gases,
nonflammable compressed gases, flammable liquids, combustible
liquids, flammable solids, corrosive acids, corrosive bases,
oxidizers, organic peroxides, spontaneously combustible
reactives, water reactives, explosives and radioactives).
2.2 Identify the chemicals used on board the ship according to
degree of polymerization.
Many simple hydrocarbons, such as ethylene and propylene, can
be transformed into polymers by adding one monomer after
another to the growing chain. Polyethylene, composed of
repeating ethylene monomers, is an addition polymer. It may
have as many as 10,000 monomers joined in long coiled chains
What are the chemical used on board ship?
Fuel additives, cooling towers, electric motor cleaners,
biological cleaners, boiler water and evaporator
chemicals, seaweed inhibitors, tank, carbon, acid, cement
cleaners, cooling water and sea water chemicals are
world-class products used in the required areas.
2.3 Explain the risks of the various chemicals used on board the s
Ships that carry
chemicals are also in
danger of causing
chemical spills that
harm other people and
the environment.
Flammable chemicals
may cause ship fires
if exposed to excess
heat, open flame, or
electric sparks, which
can injure or kill
workers on board,
especially when out to
sea.
2.4 Explain the risks of handling refrigerants.
The risks associated with the use of refrigerants in
refrigeration and air-conditioning equipment can
include toxicity, flammability, asphyxiation, and
physical hazards.
Which are the dangers to personnel when handling
refrigerant gas?
Contact with gas or liquefied gas may cause burns,
severe injury and/or frostbite. At room temperature,
most of refrigerant vapors have little or no effect on
the skin or eyes. However, in liquid form, they can
freeze skin or eyes on contact causing frostbite.
2.5 Explain the safety procedures in handling refrigerants.
Always use with adequate ventilation. Most fatal
accidents involving refrigerant are due to oxygen
deprivation; Never expose refrigerants to flames,
sparks or hot surfaces; Never trap liquid
refrigerants between valves where there is no
pressure relief device.
What are the common safety practices procedure in
handling the refrigeration and airconditioning system?
Wear safety goggles and gloves at all times when
handling refrigerants or servicing a refrigeration
system. Wear the proper respiratory protection while
working with refrigerants. Check the MSDS for the
2.6 Explain safety procedures in chemicals as per
safety data sheet ( MSDS ) and / or best industry
practices.
The MSDS lists the hazardous
ingredients of a product, its
physical and chemical
characteristics (e.g.
flammability, explosive
properties), its effect on
human health, the chemicals
with which it can adversely
react, handling precautions,
the types of measures that can
be used to control exposure,
emergency and first
2.7 Explain the mitigation procedures in
handling chemicals as per MSDS and / or best
industry practices
Controlling Exposure
1.Change process to
minimize contact with
hazardous chemicals.
2.Isolate or enclose the
process.
3.Use of wet methods to
reduce generation of
dusts or other
particulates.
4.General dilution
ventilation.
5.Use fume hoods.
