First Aid Measures
Emergency procedures for chemical exposure incidents
Remove from exposure, lie down. Remove to fresh air. If breathing is difficult, give oxygen. If not breathing, give artificial respiration. Get medical attention.
Symptoms: Difficulty in breathing. Inhalation of high vapor concentrations may cause symptoms like headache, dizziness, tiredness, nausea and vomiting
Wash off immediately with soap and plenty of water while removing all contaminated clothes and shoes. Get medical attention.
Rinse immediately with plenty of water, also under the eyelids, for at least 15 minutes. Get medical attention.
Clean mouth with water. Get medical attention.
Immediate Medical Attention
Get medical attention.
Medical Treatment
Treat symptomatically.

Handling and Storage
Safe handling precautions, storage conditions, and workplace requirements
Avoid contact with skin and eyes. Avoid contact with skin and clothing. Avoid breathing vapors or mists. Do not ingest. If swallowed then seek immediate medical assistance.
Keep in a dry, cool and well-ventilated place. Keep container tightly closed. Keep away from heat, sparks and flame. Flammables area.
Handle in accordance with good industrial hygiene and safety practice. Keep away from food, drink and animal feeding stuffs. Do not eat, drink or smoke when using this product. Remove and wash contaminated clothing and gloves, including the inside, before re-use. Wash hands before breaks and after work.
Keep away from heat, sparks and flame. Use spark-proof tools and explosion-proof equipment.
Exposure Controls / PPE
Occupational exposure limits, engineering controls, and protective equipment
Use explosion-proof electrical/ventilating/lighting/equipment. Ensure adequate ventilation, especially in confined areas. Wherever possible, engineering control measures such as the isolation or enclosure of the process, the introduction of process or equipment changes to minimise release or contact, and the use of properly designed ventilation systems, should be adopted to control hazardous materials at source
Protective gloves. Glove material: Nitrile rubber, Neoprene, Natural rubber, PVC. Breakthrough time: See manufacturers recommendations. EU standard: EN 374. Glove comments: (minimum requirement)
Wear safety glasses with side shields (or goggles) (European standard - EN 166)
No protective equipment is needed under normal use conditions. Large scale/emergency use: Use a NIOSH/MSHA or European Standard EN 136 approved respirator if exposure limits are exceeded or if irritation or other symptoms are experienced. Small scale/Laboratory use: Maintain adequate ventilation
Wear appropriate protective gloves and clothing to prevent skin exposure. Inspect gloves before use. observe the instructions regarding permeability and breakthrough time which are provided by the supplier of the gloves. (Refer to manufacturer/supplier for information) gloves are suitable for the task: Chemical compatibility, Dexterity, Operational conditions, User susceptibility, e.g. sensitisation effects, also take into consideration the specific local conditions under which the product is used, such as the danger of cuts, abrasion. gloves with care avoiding skin contamination.
