First Aid Measures
Emergency procedures for chemical exposure incidents
Remove to fresh air. If not breathing, give artificial respiration. Get medical attention if symptoms occur.
Wash off immediately with plenty of water for at least 15 minutes. If skin irritation persists, call a physician.
Rinse immediately with plenty of water, also under the eyelids, for at least 15 minutes. Get medical attention.
Clean mouth with water and drink afterwards plenty of water. Get medical attention if symptoms occur.
Immediate Medical Attention
Get medical attention.
Medical Treatment
Treat symptomatically.

Handling and Storage
Safe handling precautions, storage conditions, and workplace requirements
Wear personal protective equipment/face protection. Ensure adequate ventilation. Do not get in eyes, on skin, or on clothing. Avoid ingestion and inhalation. Avoid dust formation.
Keep container tightly closed in a dry and well-ventilated place. Keep under nitrogen.
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.
Exposure Controls / PPE
Occupational exposure limits, engineering controls, and protective equipment
Ensure that eyewash stations and safety showers are close to the workstation location. 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: Natural rubber, Nitrile rubber, Neoprene, PVC. Breakthrough time: See manufacturers recommendations. EU standard: EN 374. Glove comments: (minimum requirement). Inspect gloves before use. Please observe the instructions regarding permeability and breakthrough time which are provided by the supplier of the gloves. (Refer to manufacturer/supplier for information). Ensure 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. Remove gloves with care avoiding skin contamination.
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
