First-aid measures

1.Preamble

1.1. Indications on Safety Data Sheets (SDS) for the professional user about guidance on safe use of petroleum products, in all its aspects, should take into account that applicable legislation and general accepted practices for the management of industrial routine activities or emergencies, as well as company operating procedures, already compose a background which indicates which general actions are necessary/mandatory, advisable or unadvisable in such cases. An extensive recapitulation of all this background information will not necessarily add information value to a SDS, and may actually decrease the readability of the document, especially in an emergency. Therefore the indications meant for actual inclusion in SDSs can be focused (although not necessarily limited) to:
- Product specific issues (i.e. special hazards or characteristics)
- Key Actions (or group of actions) that are applicable in the specific case

1.2. The actual level of detail of information and its phrasing in individual SDSs may reflect local or national conventions or requirements, or company policies, but without infringing on the consistency with the information submitted hereunder. Also, more stringent national or local legal requirements or conventions will take precedence over the guidance provided in this document


2. Warning before intervention



2.1. Hydrogen sulphide (H2S) can accumulate in the headspace of product storage tanks and reach potentially hazardous concentrations.



3. Inhalation


3.1. Symptoms: irritation of the respiratory tract due to excess fume, mists or vapour exposure

3.2. If breathing is difficult, remove victim to fresh air and keep at rest in a position comfortable for breathing.

3.3. If casualty is unconscious and:
* Not breathing – ensure that there is no obstruction to breathing and give artificial respiration by trained personnel. If necessary, give external cardiac massage and obtain medical assistance.
* Breathing – place in the recovery position. Administer oxygen if necessary.

3.4. Obtain medical assistance if breathing remains difficult.

3.5. If there is any suspicion of inhalation of H2S:
- Rescuers must wear breathing apparatus, belt and safety rope, and follow rescue procedures.
- Remove casualty to fresh air as quickly as possible.
- Immediately begin artificial respiration if breathing has ceased.
-Provision of oxygen may help.
- Obtain medical advice for further treatment.


4. Skin Contact


4.1. Symptoms: dry skin, irritation in case of repeated or prolonged exposure. May cause burn in case of contact with product at high temperature

4.2. Remove contaminated clothing and footwear and dispose of safely.

4.3. Wash affected area with soap and water.

4.4. Never use gasoline, kerosene or other solvents for washing of contaminated skin.

4.5. Seek medical attention if skin irritation, swelling or redness occurs.

4.6. When using high-pressure equipment, injection of product can occur. If high-pressure injuries occur, immediately seek professional medical attention. Do not wait for symptoms to develop

4.7. For minor thermal burns: Cool the burn. Hold the burned area under cold running water for at least five minutes, or until the pain subsides. However, body hypothermia must be avoided.

4.8. Do not put ice on the burn; Remove non-sticking garments carefully. DO NOT attempt to remove portions of clothing glued to burnt skin but cut round them.

4.9. Seek medical attention in all cases of serious burns




5. Eye Contact

5.1. Symptoms: slight irritation (unspecific) . May cause burn in case of contact with product at high temperature

5.2. Rinse cautiously with water for several minutes. Remove contact lenses, if present and easy to do so. Continue rinsing.

5.3. If irritation, blurred vision or swelling occurs and persists, obtain medical advice from a specialist.

5.4. If hot product is splashed into the eye, it should be cooled immediately to dissipate heat, under cold running water. Immediately obtain specialist medical assessment and treatment for the casualty.


6. Ingestion / Aspiration


6.1. Symptoms: Few or no symptoms are expected. If any, nausea and diarrhea might occur.

6.2. Do not induce vomiting. Ask for medical assistance

6.3. Do not give anything by mouth to an unconscious person.

Fire-fighting measures

1. Product specific hazards and other issues
1.1. This substance will float and can be reignited on surface water.

2. Extinguishing Media

- Foam (Specifically trained personnel only)
- Water fog (Specifically trained personnel only)
- Dry chemical powder
- Carbon dioxide
- Other inert gases (subject to regulations)
- Sand or earth

3. Unsuitable Extinguishing Media
3.1. Do not use direct water jets on the burning product; they could cause splattering and spread the fire.
3.2. Simultaneous use of foam and water on the same surface is to be avoided as water destroys the foam.

4. Combustion Products
4.1. Incomplete combustion is likely to give rise to a complex mixture of airborne solid and liquid particulates and gases, including carbon monoxide, H2S, SOx (sulfur oxides) or sulfuric acid and unidentified organic and inorganic compounds.

5. Protective Equipment for Firefighters
5.1. In case of a large fire or in confined or poorly ventilated spaces wear full fire resistant protective clothing and self-contained breathing apparatus (SCBA) with a full face-piece operated in positive pressure mode.

Accidental release measures

1. General information

1.1. Stop or contain leak at the source if safe to do so. Avoid direct contact with released material. Stay upwind. In case of large spillages, alert occupants in downwind areas.
1.2. Keep non-involved personnel away from the area of spillage. Alert emergency personnel.
Except in case of small spillages, the feasibility of any actions should always be assessed and advised, if possible, by a trained, competent person in charge of managing the emergency.
1.3. It is recommended to eliminate all ignition sources if safe to do so (e.g. electricity, sparks, fires, flares).
1.4. When the presence of dangerous amounts of H2S around the spilled product is suspected or proved, additional or special actions may be warranted, including access restrictions, use of special protection equipment, procedures and personnel training.
1.5. If required, notify relevant authorities according to all applicable regulations.


2. Personal protection equipment for emergency responders

2.1. Small spillages: normal antistatic working clothes are usually adequate. Large spillages: full body suit of chemically resistant and antistatic material, if necessary heat resistant and insulated.
2.2. Work gloves providing adequate chemical resistance, specifically to aromatic hydrocarbons. Note: gloves made of PVA are not water-resistant, and are not suitable for emergency use.
If contact with hot product is possible or anticipated, gloves should be heat-resistant and thermally insulated.
2.3. Work helmet. Antistatic non-skid safety shoes or boots, if necessary heat-resistant.
2.4. Goggles or face shield, if splashes or contact with eyes is possible or anticipated.
2.5. Respiratory protection: A half or full-face respirator with filter(s) for organic vapours/H2S or a Self Contained Breathing Apparatus (SCBA) can be used according to the extent of spill and predictable amount of exposure. If the situation cannot be completely assessed, or if an oxygen deficiency is possible, only SCBA’s should be used.


3. Spillages onto land

3.1. Prevent product from entering sewers, rivers, waterways or other bodies of water.
3.2. If necessary dike the product with dry earth, sand or similar non-combustible materials.
3.3. Let hot product cool down naturally
3.4. Large spillages may be cautiously covered with foam, if available, to limit fire risk. Do not use direct jets
3.5. When inside buildings or confined spaces ensure adequate ventilation.
3.6. Absorb spilled product with suitable non-combustible materials.
3.7. Collect free product with suitable means. Collect recovered product and other contaminated materials in suitable containers for recycle, recovery or safe disposal.
3.8. In case of soil contamination, remove contaminated soil for remediation or disposal, in accordance with local regulations.


4. Spillages in water or at sea

4.1. Product less dense than water: In case of small spillages in closed waters (i.e. ports), contain product with floating barriers or other equipment. Collect spilled product by absorbing with specific floating absorbents
4.2. If possible, large spillages in open waters should be contained with floating barriers or other mechanical means. If this is not possible, control the spreading of the spillage, and collect the product by skimming or other suitable mechanical means.
4.3. The use of dispersants should be advised by an expert, and, if required, approved by local authorities.
4.4. Collect recovered product and other contaminated materials in suitable tanks or containers for recycle, recovery or safe disposal.
4.5. Product which is denser than water will sink to the bottom, and usually no intervention will be feasible. If possible, collect the product and contaminated materials with mechanical means, and store/dispose of according to relevant regulations. In special situations (to be assessed on case-by case basis, according to expert judgement and local conditions), excavations of trenches on the bottom to collect the product, or burying the product with sand may be a feasible option.


5. Additional information

5.1. Note: recommended measures are based on the most likely spillage scenarios for this material; however, local conditions (wind, air temperature, wave/current direction and speed) may significantly influence the choice of appropriate actions. For this reason, local experts should be consulted when necessary. Local regulations may also prescribe or limit actions to be taken.
5.2. Concentration of H2S in tank headspaces may reach hazardous values, especially in case of prolonged storage. This situation is especially relevant for those operations which involve direct exposure to the vapours in the tank.
5.3. Spillages of limited amounts of products, especially in the open air when vapours will be usually quickly dispersed, are dynamic situations, which are unlikely to entail exposure to dangerous concentrations. As H2S has a density greater than ambient air, a possible exception may regard the build-up of dangerous concentrations in specific spots, like trenches, depressions or confined spaces. In all these circumstances, however, the correct actions should be assessed on a case-by-case basis.
