Guidance on Safe Use

First-aid measures

Inhalation: Move exposed person to fresh air. Keep person warm and at rest.

If not breathing, if breathing is irregular or if respiratory arrest

occurs, provide artificial respiration or oxygen by trained personnel.

It may be dangerous to the person providing aid to give mouth-tomouth

resuscitation. Get medical attention if adverse health

effects persist or are severe. If unconscious, place in recovery

position and get medical attention immediately. Maintain an open

airway. Loosen tight clothing such as a collar, tie, belt or waistband.

Ingestion: Wash out mouth with water. Move exposed person to fresh air.

Keep person warm and at rest. If material has been swallowed

and the exposed person is conscious, give small quantities of

water to drink. Stop if the exposed person feels sick as vomiting

may be dangerous. Do not induce vomiting unless directed to do

so by medical personnel. If vomiting occurs, the head should be

kept low so that vomit does not enter the lungs. Get medical

attention. Never give anything by mouth to an unconscious person. If unconscious, place in recovery position and get medical attention

immediately. Maintain an open airway. Loosen tight clothing such

as a collar, tie, belt or waistband.

Skin contact: Flush contaminated skin with plenty of water. Remove

contaminated clothing and shoes. Get medical attention if

symptoms occur. Wash clothing before reuse. Clean shoes

thoroughly before reuse.

Eye contact: Immediately flush eyes with plenty of water, occasionally lifting the

upper and lower eyelids. Check for and remove any contact

lenses. Continue to rinse for at least 10 minutes. Get medical attention if irritation occurs.

Notes to physician Basic aid, decontamination, symptomatic treatment. Symptoms of

poisoning may not appear for several hours. Keep under medical

supervision for at least 48 hours.

Fire-fighting measures

Suitable extinguishing media: Use dry chemical, CO₂, water spray (fog) or foam.

Unsuitable extinguishing media: Do not use water jet.

Hazards from the substance or mixture: Flammable liquid. In a fire or if heated, a pressure increase will occut an dthe container may burst, with the risk of a  

subsequent explosion. Runoff to sewer may create fire or explosion hazard.

Hazardous combustion products: Decomposition products may include the following materials:

carbon oxides

Special precautions for fire-fighters: Promptly isolate the scene by removing all persons from the

vicinity of the incident if there is a fire. No action shall be taken

involving any personal risk or without suitable training. Move

containers from fire area if this can be done without risk. Use

water spray to keep fire-exposed containers cool.

Special protective equipment for fire-fighters: Fire-fighters should wear appropriate protective equipment and selfcontained

breathing apparatus (SCBA) with a full face-piece

operated in positive pressure mode.

Accidental release measures

Personal precautions, protective equipment and emergency procedures: No action shall be taken involving any personal risk or without

suitable training. 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. Put

on appropriate personal protective equipment.

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).

Methods and materials for containment and cleaning up

Small spill: Stop leak if without risk. Move containers from spill area. Dilute

with water and mop up if water-soluble or absorb with an inert dry

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.

Large spill: Stop leak if without risk. Move containers from spill area. Prevent

entry into sewers, water courses, basements or confined areas.

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.

Handling and storage

Manufacture and use of this chemical intermediate take place under strictly controlled conditions, as described in Art. 17/18 REACH. The substance is rigorously contained during manufacturing and use and appropriate risk management measures including PPE (e.g. during charging or sampling) are applied. Occupational exposure is reduced to a minimum and well controlled by measurements. A management system covering all general aspects of a chemical production is in place, especially cleaning and maintenance of plants and equipment. An authorisation scheme based on instructions covering the whole process ensures that only trained and authorised staff handles the substance.

Precautions for safe handling:

Put on appropriate personal protective equipment..

Eating, drinking and smoking should be prohibited in areas where

this material is handled, stored and processed. Workers should

wash hands and face before eating, drinking and smoking. Do not

breathe vapour or mist. Do not ingest. Avoid contact with eyes, skin

and clothing. Use only with adequate ventilation. Wear appropriate

respirator when ventilation is inadequate. Do not enter storage

areas and confined spaces unless adequately ventilated. Keep in

the original container or an approved alternative made from a

compatible material, kept tightly closed when not in use. Store and

use away from heat, sparks, open flame or any other ignition

source. Use explosion-proof electrical (ventilating, lighting and

material handling) equipment. Use non-sparking tools. Take

precautionary measures against electrostatic discharges. To avoid

fire or explosion, dissipate static electricity during transfer by

earthing and bonding containers and equipment before transferring

material. Empty containers retain product residue and can be

hazardous. The product is registered with strictly controlled

conditions as defined in Article 17(3) or 18(4) of regulation (EC) no.

1907/2006 (REACH Regulation) and must therefore be handled as

such. Refer to the industry guidance prepared by Concawe/Cefic/

EFCG for advice on the confirmation of strictly controlled conditions.

Conditions for safe storage, including any incompatibilities:

Store in accordance with local regulations. Store in a segregated

and approved area. Store in original container protected from direct

sunlight in a dry, cool and well-ventilated area, away from

incompatible materials and food and drink.

Eliminate all ignition sources. Separate from oxidizing materials.

Keep container tightly closed and sealed until ready for use.

Containers that have been opened must be carefully resealed and

kept upright to prevent leakage. Do not store in unlabelled containers. Use appropriate containment to avoid

environmental contamination.
