Guidance on Safe Use

First-aid measures

solid:

Inhalation: Move exposed person to fresh air. If it is suspected that fumes are still present, the rescuer should wear an appropriate mask or

selfcontained breathing apparatus. 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-to-mouth resuscitation. Get

medical attention. 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. In the event of any complaints or symptoms, avoid further exposure.

liquid:

Inhalation: Remove victims from the danger zone without endangering your own safety. Move affected person to fresh air. If patient has difficulty

in breathing, administer oxygen, keep him calm and protect him from loss of warmth. Get medical attention.

solid:

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 personis 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 immediatelyMaintain an open airway. Loosen tight clothing such as a collar, tie, belt or waistband.

liquid:

Ingestion: Wash out mouth with water. Ensure that the patient drinks water. In any case consult a physician.

solid:

Skin contact: Flush contaminated skin with plenty of water. Remove contaminated clothing and shoes. Continue to rinse for at least 10 minutes. Get medical attention. In the event of any complaints or symptoms, avoid further exposure. Wash clothing before reuse. Clean shoes thoroughly before

reuse.

liquid:

Skin contact: Wash skin immediately with plenty of water and soap. Call a physician. CONTACT WITH THE HOT MELT: Cooling immediately with plenty of water. Do not remove product crusts which may have formed neither forcibly nor by applying any solvents to the skin involved. In order to obtainmedical care for possible burns and for a smooth cleansing of the skin, seek medical advice immediately.

solid:

Eye contact: Get medical attention immediately. 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. Chemical burns must be treated promptly by a physician.

liquid:

Eye contact: Immediately flush eyes with running water for at least 15 minutes, keeping eyelids open. Seek immediate medical attention.

Fire-fighting measures

solid / liquid:

Extinguishing media

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

Not suitable: None Known.

Special exposure hazards: No specific fire or explosion hazard.

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.

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

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

solid / liquid:

Personal precautions: 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. Provide adequate ventilation. Put on appropriate personal protective equipment (see

section 8).

Environmental precautions: Avoid dispersal of spilled 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: Move containers from spill area. Prevent entry into sewers, water courses, basements or confined areas. Vacuum or sweep up material

and place in a designated, labelled waste container. Dispose of via a licensed waste disposal contractor. Note: see section 1 for emergency contact

information and section 13 for waste disposal.

Small spill: Move containers from spill area. Vacuum or sweep up material and place in a designated, labelled waste container. Dispose of via a

licensed waste disposal contractor.

Handling and storage

solid / liquid:

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. Persons with a history of skin sensitisation problems or asthma, allergies or chronic or recurrent respiratory disease should not be employed in any process in which this

product is used. Do not get in eyes or on skin or clothing. Do not ingest. Use only with adequate ventilation. Wear appropriate respirator when

ventilation is inadequate. Keep in the original container or an approved alternative made from a compatible material, kept tightly closed when not in

use. Empty containers retain product residue and can be hazardous.

solid:

Storage: Store in accordance with local regulations. Store in original container protected from direct sunlight in a dry, cool and wellventilated area,

away from incompatible materials (see section 10) and food and drink. 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.

liquid:

Storage: Store between the following temperatures: 150 to 190°C. Store in accordance with local regulations. Store in a dry place. 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.

Recommended monitoring procedures: If this product contains ingredients with exposure limits, personal, workplace atmosphere or biological

monitoring may be required to determine the effectiveness of the ventilation or other control measures and/or the necessity to use respiratory

protective equipment. Reference should be made to European Standard EN 689 for methods for the assessment of exposure by inhalation to

chemical agents and national guidance documents for methods for the determination of hazardous substances.

Risk management measures
