First Aid Measures
Emergency procedures for chemical exposure incidents
Remove to fresh air. Get medical attention if symptoms occur. If not breathing, give artificial respiration.
Wash off immediately with plenty of water for at least 15 minutes. Get medical attention if symptoms occur.
Rinse immediately with plenty of water, also under the eyelids, for at least 15 minutes. Get medical attention if symptoms occur.
Do NOT induce vomiting. Get medical attention.
Medical Treatment

Handling and Storage
Safe handling precautions, storage conditions, and workplace requirements
Wear personal protective equipment/face protection. Ensure adequate ventilation. Avoid contact with skin, eyes or clothing. Avoid ingestion and inhalation. Avoid dust formation.
Keep containers tightly closed in a dry, cool and well-ventilated place.
Handle in accordance with good industrial hygiene and safety practice.
Exposure Controls / PPE
Occupational exposure limits, engineering controls, and protective equipment
Ensure adequate ventilation, especially in confined areas. Ensure that eyewash stations and safety showers are close to the workstation location.
Protective gloves. Glove material: Natural rubber, Nitrile rubber, Neoprene, 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)
When workers are facing concentrations above the exposure limit they must use appropriate certified respirators.
