Hazardous Substances:
The generic names or the general danger
Acetylene
Acetylene is not especially toxic but it can contain toxic impurities such as traces of phosphine and arsine. It is also highly flammable, combustion of acetylene with oxygen produces a flame of over 3600 K (3300 °C, 6000 °F), releasing 11.8 kJ/g. Oxyacetylene is the hottest burning common fuel gas. Its singular hazard is associated with its intrinsic instability, especially when it is pressurized. Samples of concentrated or pure acetylene can easily react in an addition-type reaction to form a number of products, typically benzene and/or vinyl acetylene. These reactions are exothermic, and unlike other common flammables, do not require oxygen to proceed. Consequently, acetylene can explode with extreme violence if the BVolute pressure of the gas exceeds about 200 kPa (29 psi).
Physical & Chemical Behaviour:
Ignition of an acetylene leak could cause fires and explosions which could damage equipment on the Vessel and potentially injure her crew.
Potential harm to
people & environment:
Oxygen
Oxygen is a nontoxic odourless, colourless, tasteless gas. It is naturally present in the air (21%) and is essential for life.
Physical & Chemical Behaviour:
Increased levels of oxygen promote rapid combustion.
Potential harm to
people & environment:
Marine Gas Oil
Marine Gas Oil is a blend of diesel fuel and is thus flammable. It may be fatal if swallowed, harmful if inhaled and causes skin irritation. It may cause damage to organs through prolonged or repeated exposure. It is toxic to aquatic life with long lasting effects.
Physical & Chemical Behaviour:
Diesel spills would cause pollution to the surrounding and would require clean up. Ignition of diesel spills could damage equipment on the Vessel and potentially injure her crew.
