Precautions against transportation of Phenol

Phenol is one of the solidify cargoes which special precautions are required when vessel transports the cargo. The Phenol is a extremely toxic & corrosive chemical.

The solution of Phenol causes severe chemical burns to the intact skin, which are usually painless. It appears as white wrinkled "dead skin". In case of eye contact, permanent damage to the eye may occur. In case of inhalation, there will be a burning sensation of the mouth and throat. The patient can also develop mental agitation, confusion, heart failure and circulatory collapse.

The lack of care and attention against the handling of Phenol may be involved in accidents which can be damaged to crew, cargo or structures.

Following are some basic safety procedure for marine transportation Phenol in bulk :

Before Loading

  1. To test drain lines, valves, flange parts, pipe lines of cargo tank to be loaded if there is any leakage. You have to bear in mind that once the cargo started loading, it cannot stop pumping for repairing any leakage through the loading because the cargo will be solidified immediately in pipe line.


  2. To test heating coil in cargo tank without fail. Leaking of heating coil during voyage with cargo heating can be damaged to cargo which easily reacted with water and discoloured to red.


  3. To check emergency showers are in good condition so that it can be used in emergency case, and fresh water with bucket is to provide near manifold when connecting or disconnecting cargo hose and near cargo tank when sampling from cargo tank.


  4. Safety equipment such as gas masks, shield masks, goggles, rubber gloves, rubber boots, and chemical suits should be provided near manifold to ready for immediate use.


  5. The crew engaging in cargo operation has to put the safety equipment


  6. Flange part connected with shore line on manifold is to be covered with rubber sheet in order to avoid cargo splashing and damaged to crew.

Recommendations for chemical tankers with respect to carriage of Phenol

  1. Ensure the suitability of the vessel for carrying such products with respect to its stowage restrictions and operations on the whole.
  2. Ensuring crew is well informed and trained to handle such cargoes.
  3. Ensuring a blend of experienced officer and crew on board so as to Properly train the inexperienced staff for their future endeavours With specific cargo operations
  4. Proper check/pressure testing of lines and valves prior loading.
  5. To use common line for phenol handling is not preferred.
  6. To use deck heaters with single valve segregation towards common line is not sufficient as a barrier.

Sampling precautions : Open sampling should never be encouraged

Closed Sampling system should be used at all times. Phenol is extremely dangerous when comes into contact with the eyes or skin and can be fatal. Extreme precaution to be taken when opening any access to tanks having phenol. All personnel engaged in Phenol operation must wear full protection clothing at all times.

Gas Tight Suit and self-contained breathing apparatus to be worn by personnel engaged in sampling. Chemical splash suit should never be used for this purpose.

Risk Assessment to be prepared to identify and mitigate all associated risk involved. Risk control measures to be taken and same to be discussed before commencement of such operation.Everyone on board should be thoroughly familiar with handling of Phenol and precaution required for carriage.


Remarks: Phenol is made of Benzene & Cumene which have a strong washing ability itself by its activity and corrosiveness. Therefore it is no effect to use detergent in order to remove smell of Phenol. To overcome strong smell, it is recommended to use hot water not less than 70C and steaming.

Good practices

High melting point cargoes such as Phenol, Palm fatty acid distillates lauric and Stearic acid has inherent property to form lumps of cargo. It is therefore recommended to turn the cargo pumps at regular intervals during the voyage and prior to discharge in order to avoid any last minute surprises. All the lines to be then blown back to the cargo tanks.

The danger of frozen valves, pressure/vacuum in the tanks to be monitored during loading, voyage and discharge. In the event if any of the pumps are found frozen, deployment of portable Framo pump should not be considered without a proper Risk assessment and office permission.

Hazards of Phenol - safe handling of Phenol on chemical tankers.
Phenol is derived from the basic raw materials of benzene and propylene. Phenol is typically a solid at room temperature as it solidifies at 41C (106 F). Plywood, window glazing, DVDs, computers, automotive parts and LCD/LED TVs are some of the many items that rely on this important raw material. .....

handling Phenol safety precautions
PHENOL is carried at sea in a generally pure state. As a result, it has a high freezing point of approximately 40~ 41deg C. PHENOL is also extremely dangerous when it comes into contact with the eyes or skin and can be fatal. .....
