Acetic acid

Guidance on Safe Use

First-aid measures

Eye contact: In case of contact, immediately flush eyes with plenty of water for at least 15 minutes.  Get medical attention immediately.

Skin contact: Immediately wash exposed skin with soap and water. Remove contaminated clothing and shoes.  Wash clothing before reuse.  Clean shoes thoroughly before reuse.  Get medical attention immediately.

Inhalation: If inhaled, remove to fresh air.  If not breathing, give artificial respiration.  If breathing is difficult, give oxygen.  Get medical attention immediately.

Ingestion: Do not induce vomiting unless directed to do so by medical personnel.  Never give anything by mouth to an unconscious person.  Get medical attention immediately.  If swallowed, rinse mouth with water (only if the person is conscious).  If affected person is conscious, give plenty of water to drink.

Fire-fighting measures

Extinguishing media - Suitable: In case of fire, use water fog, alcohol resistant foam, dry chemical or carbon dioxide extinguisher or spray.  Not suitable Do not use water jet.

Hazardous Decomposition Products: Decomposition products may  include the following materials : carbon oxides

Unusual fire/explosion Hazards: Flammable liquid and vapour. Vapours may form explosive mixtures with air. Vapours may accumulate in low or confined areas or travel a considerable distance to a source of ignition and flash back. Runoff to sewer may create fire or explosion hazard. This material is not explosive as defined by established regulatory criteria.

Accidental release measures

Personal precautions: No action shall be taken involving any personal risk or without suitable training. Evacuate surrounding areas. Keep unnecessary and unprotected personnel from entering. Do not touch or walk through spilt material. Shut off all ignition sources. No flares, smoking or flames in hazard area. Avoid breathing vapour or mist. Provide adequate ventilation. Wear appropriate respirator when ventilation is inadequate.

Put on appropriate personal protective equipment  

Respiratory protection If ventilation is inadequate, use  espirator that will protect against organic vapour and dust/mist. Provided an air-filtering/air-purifying respirator is suitable, a combination filter for particles, organic gases and vapours (boiling point >65°C) can be used. Use filter type AP or comparable standard. Respiratory protective equipment must be checked to ensure it fits correctly each time it is worn. Air-filtering respirators, also called air-purifying respirators, will not be adequate under conditions of oxygen deficiency (i.e. low oxygen concentration), and would not be considered suitable where airborne concentrations of chemicals with a significant hazard are present. In these cases air-supplied breathing apparatus will be required. If concentration is unknown, a Self-Contained Breathing Apparatus (SCBA) should be used to avoid inhalation of the product.

Hand protection Wear gloves that cannot be penetrated by chemicals or oil. (Butyl rubber gloves.)  The correct choice of protective gloves depends upon the chemicals being handled, the conditions of work and use, and the condition of the gloves (even the best chemically resistant glove will break down after repeated chemical exposures). Most gloves provide only a short time of protection before they must be discarded and replaced. Because specific work environments and material handling practices vary, safety procedures should be developed for each intended application. Gloves should therefore be chosen in consultation with the supplier/manufacturer and with a full assessment of the working conditions.

Eye protection Do not get in eyes. Wear face shield. Chemical splash goggles.

Skin and body Do not get on skin or clothing. Wear clothing and footwear that cannot be penetrated by chemicals or oil. Suitable protective equipment may include:Hard hat., Chemical resistant boots. Chemical resistant apron, Full chemical protective suit with a hood .Chemical protective suit consisting of a jacket and trousers. The jacket should be buttoned up to the neck,sleeves sealed at the gloves, and trouser legs worn outside the boots. These precautions are required to prevent the clothing from accidentally trapping product against the skin.

Environmental precautions Avoid dispersal of spilt material and runoff and contact with soil, waterways, drains and sewers. Inform the relevant authorities if the product has caused environmental pollution (sewers, waterways, soil or air).

Large spill Stop leak if without risk. Move containers from spill area. Approach the release from upwind. Prevent entry into sewers, water courses, basements or confined areas. Wash spillages into an effluent treatment plant or proceed as follows. Contain and collect spillage with non-combustible, absorbent material e.g.sand, earth, vermiculite or diatomaceous earth and place in container for disposal according to local  regulations . Use spark-proof tools and explosion-proof equipment. Dispose of via a licensed waste disposal contractor. Contaminated absorbent material may pose the same hazard as the spilt product.

Small  spill Stop leak if without risk. Move containers from spill area. Absorb with an inert material and place in an appropriate waste disposal container. Use spark-proof tools and explosion-proof equipment. Dispose of via a licensed waste disposal contractor.

Handling and storage

Handling: Do not get in eyes, on skin or on clothing.  Use only with adequate ventilation.  Do not breathe vapour or mist. Keep away from heat, sparks and flame.  To avoid fire or explosion, dissipate static electricity during transfer by earthing and bonding containers and equipment before transferring material.  Use explosion-proof electrical (ventilating, lighting and material handling) equipment.  Wash thoroughly after handling. Empty containers may contain toxic, flammable/combustible or explosive residue or vapours. Do not cut, grind, drill, weld, reuse or dispose of containers unless adequate precautions are taken against these hazards.

Storage: Store in a segregated and approved area.  Keep container in a cool, well-ventilated area.  Keep container tightly closed and sealed until ready for use.  Avoid all possible sources of ignition (spark or flame).
