Guidance on Safe Use

First-aid measures

Inhalation : Get medical attention immediately. Remove victim to fresh air and keep at rest in a

position comfortable for breathing. If it is suspected that fumes are still present, the

rescuer should wear an appropriate mask or self-contained breathing apparatus. 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-to-mouth resuscitation. 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 : Get medical attention immediately. Flush contaminated skin with plenty of water.

Remove contaminated clothing and shoes. Wash contaminated clothing thoroughly

with water before removing it, or wear gloves. Continue to rinse for at least 10

minutes. Chemical burns must be treated promptly by a physician. Wash clothing

before reuse. Clean shoes thoroughly before reuse.

Ingestion : Get medical attention immediately. Wash out mouth with water. Remove dentures if

any. Remove victim to fresh air and keep at rest in a position comfortable for

breathing. 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. Chemical burns must be treated promptly by a physician.

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.

Protection of first-aiders : No action shall be taken involving any personal risk or without suitable training. If it is

suspected that fumes are still present, the rescuer should wear an appropriate mask

or self-contained breathing apparatus. It may be dangerous to the person providing

aid to give mouth-to-mouth resuscitation. Wash contaminated clothing thoroughly

with water before removing it, or wear gloves.

Fire-fighting measures

Suitable extinguishing media : Use an extinguishing agent suitable for the surrounding fire.

Hazards from the substance or mixture : In a fire or if heated, a pressure increase will occur and the container may burst.

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

carbon dioxide

carbon monoxide

sulfur 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.

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

breathing apparatus (SCBA) with a full face-piece operated in positive pressure

mode. Clothing for fire-fighters (including helmets, protective boots and gloves)

conforming to European standard EN 469 will provide a basic level of protection for

chemical incidents.

Accidental release measures

For non-emergency personnel : 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. Do not breathe vapour or mist.

Provide adequate ventilation. Wear appropriate respirator when ventilation is

inadequate. Put on appropriate personal protective equipment.

For emergency responders : If specialised clothing is required to deal with the spillage, take note of any

information in Section 8 on suitable and unsuitable materials.

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).

Small spill : Stop leak if without risk. Move containers from spill area. Dilute with water and mop

up if water-soluble. Alternatively, or if water-insoluble, absorb with an inert dry

material and place in an appropriate waste disposal container. Dispose of via a

licensed waste disposal contractor.

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. The spilled material may be neutralized with sodium

carbonate, sodium bicarbonate or sodium hydroxide. Dispose of via a licensed

waste disposal contractor. Contaminated absorbent material may pose the same

hazard as the spilt product.

Handling and storage

Precautions for safe handling

Protective measures : Put on appropriate personal protective equipment. Do not get in

eyes or on skin or clothing. Do not breathe vapour or mist. Do not ingest. If during

normal use the material presents a respiratory hazard, use only with adequate

ventilation or wear appropriate respirator. Keep in the original container or an

approved alternative made from a compatible material, kept tightly closed when not

in use. Keep away from alkalis. Empty containers retain product residue and can be

hazardous. Do not reuse container.

Advice on general occupational hygiene : 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. Remove contaminated clothing and protective

equipment before entering eating areas.

Conditions for safe storage, including any incompatibilities : Store between the following temperatures: 5 to 40°C (41 to 104°F). Store in

accordance with local regulations. Store in original container protected from direct

sunlight in a dry, cool and well-ventilated area, away from incompatible materials and food and drink. Separate from alkalis. 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.
