Notes to physician

In case of inhalation of decomposition products in a fire, symptoms may be delayed.

The exposed person may need to be kept under medical surveillance for 48 hours.

Fire-fighting measures

Extinguishing media

Suitable: use dry chemical, CO2, Water spray (fog) or foam

not suitable: do not use water jet

Special exposure hazards: combustible liquid. In a fire or if heated a pressure increase will occur and the container may burst, with the risk of a subsequent explosion. Promptly isolate the scene by removing all person from the vicinity of the incident if there is a fire. No action shall be taken involving any persona 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.

Hazardous thermal decomposition products:

Decomposition products may include the following materials:

carbon dioxide

carbon monoxide

nitrogen oxides

phosphorus oxides

Special protective equipment for fire-fighters:

Fire-fighters should wear appropriate protective equipment and self-contained breathing apparatus with a full face-piece operated in positive pressure mode. Clothing for fire-fighters (include helmets, protective boots and gloves) conforming to European standard EN 469 will provide a basic level of protection for chemical incidents

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. Put on appropriate personal protective

equipment (see Section 8).

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 for cleaning up

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. 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. 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.

Handling and storage

Handling

Put on appropriate personal protective equipment (see Section 8). 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. Use only with adequate ventilation. Wear appropriate respirator when

ventilation is inadequate. Do not enter storage areas and confined spaces unless

adequately ventilated. 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.

Storage

Do not store above the following temperature: 40°C (104°F). 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 (see section 10) 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.

Packaging materials

Recommended : Use original container.
