Acetylene (dissolved)

Remove victim to uncontaminated area wearing self contained breathing apparatus. Keep victim warm and rested. Call a doctor. Apply artificial respiration if breathing stopped.

Symptoms: In high concentrations may cause asphyxiation. Symptoms may include loss of mobility/consciousness. Victim may not be aware of asphyxiation. In low concentrations may cause narcotic effects. Symptoms may include dizziness, headache, nausea and loss of co-ordination.

Ingestion is not considered a potential route of exposure

Water spray or fog, Dry powder

Do not use water jet to extinguish, Carbon dioxide

Exposure to fire may cause containers to rupture/explode

Use fire control measures appropriate for the surrounding fire. Exposure to fire and heat radiation may cause gas receptacles to rupture. Cool endangered receptacles with water spray jet from a protected position. Prevent water used in emergency cases from entering sewers and drainage systems. If possible, stop flow of product. Use water spray or fog to knock down fire fumes if possible. Do not extinguish a leaking gas flame unless absolutely necessary. Spontaneous/explosive re-ignition may occur. Extinguish any other fire. Continue water spray from protected position until container stays cool. Move containers away from the fire area if this can be done without risk.

Try to stop release; Consider the risk of potentially explosive atmospheres; Act in accordance with local emergency plan; Stay upwind; Ventilate area

Try to stop release

The product must be handled in accordance with good industrial hygiene and safety procedures. Only experienced and properly instructed persons should handle gases under pressure. Consider pressure relief device(s) in gas installations. Ensure the complete gas system was (or is regularly) checked for leaks before use. Do not smoke while handling product. Use only properly specified equipment which is suitable for this product, its supply pressure and temperature. Avoid suck back of water, acid and alkalis. Assess the risk of potentially explosive atmospheres and the need for explosion-proof equipment. Purge air from system before introducing gas. Take precautionary measures against static discharge. Keep away from ignition sources (including static discharges). Consider the use of only non-sparking tools. Avoid contact with pure copper, mercury, silver and brass with greater than 65% copper. Do not use alloys containing more than 43% silver. Operating pressure in piping should be limited to 1.5 bar (gauge) or less. Consider the use of flash back arrestors. Solvent may accumulate in piping systems. Do not breathe gas. Avoid release of product into atmosphere.

Containers should be stored in the vertical position and properly secured to prevent them from falling over. Keep container below 50°C in a well ventilated place. Store containers in location free from fire risk and away from sources of heat and ignition. Keep away from combustible materials. Segregate from oxidant gases and other oxidants in store.

The product must be handled in accordance with good industrial hygiene and safety procedures. Do not smoke while handling product. For maintenance activities use appropriate resistant gloves, assess the necessity to use a respiratory filter device and wear safety goggles.

Provide adequate general and local exhaust ventilation. Systems under pressure should be regularly checked for leakages. Gas detectors should be used when flammable gases/vapours may be released. The substance is not classified for human health hazards or for environment effects and it is not PBT or vPvB so that no exposure assessment or risk characterisation is required. For tasks where the intervention of workers is required, the substance must be handled in accordance with good industrial hygiene and safety procedures. Consider the use of a work permit system e.g. for maintenance activities

Wear working gloves when handling gas containers. Standard EN 388 - Protective gloves against mechanical risk

Wear safety glasses with side shields. Standard EN 166 - Personal eye-protection - specifications

None necessary

Consider the use of flame resistant anti-static safety clothing. Standard EN ISO 14116 - Limited flame spread materials. Standard EN ISO 1149-5 - Protective clothing: Electrostatic properties. Wear safety shoes while handling containers. Standard EN ISO 20345 - Personal protective equipment - Safety footwear

Refer to local regulations for restriction of emissions to the atmosphere. See section 13 for specific methods for waste gas treatment.

Dissolved in a solvent supported in a porous mass. Stable under recommended handling and storage conditions (see section 7)

No reactivity hazard other than the effects described in sub-sections below

May react violently with oxidants. Can form explosive mixture with air. May react explosively even in the absence of air. May decompose violently at high temperature and/or pressure or in the presence of a catalyst

Keep away from heat/sparks/open flames/hot surfaces. – No smoking. High temperature. High pressure

Forms explosive acetylides with copper, silver and mercury. Do not use alloys containing more than 65% copper. Air, Oxidisers. Do not use alloys containing more than 43% silver. For additional information on compatibility refer to ISO 11114

Under normal conditions of storage and use, hazardous decomposition products should not be produced

Avoid discharge to atmosphere. Do not discharge into areas where there is a risk of forming an explosive mixture with air. Waste gas should be flared through a suitable burner with flash back arrestor. Ensure that the emission levels from local regulations or operating permits are not exceeded. Refer to the EIGA code of practice Doc.30 'Disposal of Gases', downloadable at http://www.eiga.org for more guidance on suitable disposal methods

Dispose of cylinder via gas supplier only.

Avoid transport on vehicles where the load space is not separated from the driver's compartment. Ensure vehicle driver is aware of the potential hazards of the load and knows what to do in the event of an accident or an emergency. Before transporting product containers: - Ensure there is adequate ventilation - Ensure that containers are firmly secured - Ensure cylinder valve is closed and not leaking - Ensure valve outlet cap nut or plug (where provided) is correctly fitted - Ensure valve protection device (where provided) is correctly fitted.
