CONTEXTUALIZACIÓN DEL MODELO

It is important to ensure that the tubes that are ordered and supplied are of the same manufacturer as the Toxic Gas Detector – Draeger tubes for the Draeger Accuro analyser, and so on.

For more detail about Benzene and its Threshold Limit Value (TLV), refer to the DCOM(T) Part B: Cargo Operations Petroleum – Chapter 1 or Part C: Cargo Operations Chemical – Chapter 1.

6.2.4 Stocks of Chemical Tubes

Vessels carrying chemicals must carry a standard stock of gas detector tubes in accordance with the list CCR74 – List of Toxic Gas Detector Tubes to be Carried. Additional tubes for specific cargoes will also be required and these should be obtained prior to loading the particular cargo. If the correct tubes cannot be obtained the company must be immediately informed prior to loading the cargo.

Detector tubes are to be checked at least every 3 months and the record ECF26 - Analyser - Toxic Gas Detection Tubes maintained. Replacement tubes must be ordered in good time prior to the expiry of the tubes on board.

6.3 Fixed Gas Detection Systems

Fixed gas detection equipment, including that for the pump room, must be checked with the manufacturer’s recommended calibration gas at monthly intervals and the record ECF23 - Analyser - Fixed Gas Detection System maintained. The vessel must ensure that the correct calibration gas is available and that replacement gas is ordered before the expiry date.

Fixed gas detection system control boxes should be labelled in a convenient position with the type of type of calibration gas to be used.

Fixed gas detection systems are to be considered critical equipment, and any failure must be immediately reported to the company.

If there is a failure of the ballast tank fixed gas detection system then ballast tanks and any other compartment adjacent to loaded compartments, such as cofferdams, void spaces and spool tanks which are served by the equipment must be checked on a daily basis and the results recorded in the ECF30 - Atmosphere Check – Cargo and Other Spaces.

Calibration gas should be checked every 3 months and the record ECF22 - Analyser – Calibration Gas maintained. Replacement canisters must be ordered in good time before those on board expire.

6.4 Personal Protective Equipment 6.4.1 General Provisions

It is the responsibility of every seafarer to wear appropriate personal protective equipment for the tasks they are involved in. The minimum PPE for anyone working on deck during cargo operations is a safety helmet, safety boots, overall, gloves and, if necessary, goggles.

Anyone not involved in cargo operations proceeding on deck during cargo operations must wear safety helmet, safety boots, and suitable clothing which covers both the arms and legs.

In addition, where the MSDS of a particular cargo recommends the use of additional safety equipment, this must be readily available. Seafarers must be aware of the dangers of dermatitis and skin cancer from prolonged contact with various oils and chemical substances.

6.4.2 Safety Helmets

Safety helmets are provided to protect the wearer against falling objects and against head knocks.

Helmets which have suffered a large impact must be discarded. It is not permitted to paint or mark a safety helmet with adhesive tape or labels, as this can significantly reduce the protection they offer.

6.4.3 Hearing Protection

There are two types of hearing protection generally available – ear defenders and ear plugs.

The latter come in various types.

Ear defenders offer the best protection and should be worn by all personnel working in areas of high noise, including the engine room and associated compartments, pump rooms, aggregate pump rooms, and when using high noise equipment such as that for scaling or grinding.

6.4.4 Face and Eye Protection

Risk of eye injury may occur through a variety of reasons, and it is the responsibility of each person to ensure that they are wearing appropriate eye protection for the task they are involved in. Examples of risk to eyes are:

• Infra red rays from gas welding;

• Ultra violet rays from electric welding;

• Foreign particles;

• Chemical splashes;

Various types of goggles, glasses and face shields or visors are available to protect against these hazards and each is designed for a specific purpose.

6.4.5 Respiratory Protection and the Use of Filter Masks

Under no circumstances is it permitted to use filter masks as protection against cargo or chemical vapours.

6.4.6 Hand Protection

The type of protection required will depend on the work undertaken. Whenever sharp objects are being handled, leather palmed gloves should always be used. When handling hot objects, heat-resistant gloves should be used.

When handling chemicals or corrosive substances, rubber, synthetic or PVC gloves should be worn.

When handling mooring wires, leather palmed gloves should be worn, but mooring wires should not handled wearing gloves during the deployment of wires overboard in case the glove becomes entangled in the wire with subsequent danger to the wearer.

6.4.7 Foot Protection

Most foot injury results from the wearing of improper footwear such as sandals, trainers or flip-flops. All personnel should wear the appropriate footwear for the activity they are undertaking. Safety boots or shoes must be worn whenever at work, be it on deck, in machinery spaces or in the galley.

Whenever a seafarer proceeds on deck or into a machinery space for non-work purposes, suitable footwear must be worn.

6.4.8 Body Protection

The company provides all seafarers with overalls. These should be reasonably close fitting and should be worn without scarves, belts, loose flaps, or bulging pockets. They shall be correctly closed with the buttons or zips. Sleeves must not be rolled up during work where there is risk of injury to the arms.

Overalls shall be kept as clean as possible for reasons of health and hygiene. When in port the company expects every seafarer to wear clean overalls in order that the standards of the company are seen by outsiders to be high.

Whenever an overall becomes unserviceable for any reason, be it such damage that it no longer offers full protection, or becomes unpresentable, then a replacement should be requested.

6.4.9 High Visibility Jackets

High visibility jackets shall be worn where there is a need to be seen, for example during cargo operations on dry cargo vessels.

6.4.10 Handling Chemicals

Specialised protective equipment such as rubber or leather aprons, gloves and full face protection may be required when handling chemicals, maintaining emergency batteries or welding.

6.4.11 Oxygen Resuscitator

When handling either a petroleum or chemical cargo, an oxygen resuscitator must be immediately available. During cargo operations the resuscitator must not be kept in a locked hospital or medical locker.
