1.Preamble1.1. 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 case1.2. 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 intervention2.1 Spillages make surface slippery2.2 Before attempting to rescue casualties, isolate area from all potential sources of ignition including disconnecting electrical supply.2.3 Ensure adequate ventilation and check that a safe, breathable atmosphere is present before entry into confined spaces.2.4 (Subject to applicability) Hydrogen sulphide (H2S) can accumulate in the headspace of storage tanks and reach potentially hazardous concentrations.
3 Inhalation 3.1 Inhalation at ambient temperature is unlikely because of the low vapour pressure of the substance. Exposure to vapours may however occur when the substance is handled at high temperatures with poor ventilation.3.2 Symptoms: May cause: headache, nausea, dizziness. Acute, high dose exposure may cause: central nervous system depression including confusion, altered mental status, seizures, cardiac arrhythmias. 3.3 Move to well-ventilated area. 3.4 Check vital signs regularly and act accordingly. 3.5 (subject to applicability) 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: Skin irritation. 4.2 Remove contaminated, saturated clothing immediately. 4.3 Wash area with soap and water for 10 to 15 minutes.
5 Eye Contact 5.1 Symptoms: May cause mild reversible eye irritation. 5.2 Remove contact lenses. 5.3 Irrigate exposed eyes with 0.9% normal saline if available or water for at least 15 minutes. 5.4 Irrigate before and after removing the lenses to prevent a carry-over of the substances to the shielded area of the lens.
6 Ingestion/aspiration 6.1 Incidental oral exposure: aspiration hazard; may be fatal if it enters the airways after swallowing. 6.2 IF SWALLOWED: Immediately call a POISON CENTRE or doctor/ physician. Do NOT induce vomiting. If vomiting does occur, have victim lean forward to reduce risk of aspiration.
1. Product specific hazards and other issues1.1. 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 earth3. Unsuitable Extinguishing Media3.1. 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 Products4.1. Incomplete combustion is likely to give rise to a complex mixture of airborne solid and liquid particulates and gases, including carbon monoxide and unidentified organic and inorganic compounds.4.2. If sulfur compounds are present in appreciable amounts, combustion products may include also H2S and SOx (sulfur oxides) or sulfuric acid. 5. Protective Equipment for Firefighters5.1. 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.
1. General information1.1. 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. Eliminate all ignition sources if safe to do so (e.g. electricity, sparks, fires, flares). 1.4. (Subject to applicability): In those cases 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 responders2.1. Small spillages: normal antistatic working clothes are usually adequate. Large spillages: full body suit of chemically resistant and antistatic material.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.2.3. Work helmet. Antistatic non-skid safety shoes or boots2.4. 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 (and when applicable for 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 Land3.1. Prevent product from entering sewers, rivers, waterways or other bodies of water3.2. If necessary dike the product with dry earth, sand or similar non-combustible materials.3.3. Large spillages may be cautiously covered with foam, if available, to limit fire risk. Do not use direct jets3.4. When inside buildings or confined spaces, ensure adequate ventilation.3.5. Absorb spilled product with suitable non-combustible materials.3.6. Collect free product with suitable means. Transfer collected product and other contaminated materials to suitable containers for recycle, recovery or safe disposal.3.7. In case soil contamination, remove contaminated soil and treat this in accordance with local regulations.4. Spillages on water or at sea4.1. 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 materials in suitable tanks or containers for recovery or safe disposal.5. Additional information5.1. 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. (Subject to applicability): 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. (Subject to applicability): 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.
