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.
Medical Treatment
Treat symptomatically.
Firefighting Measures
Extinguishing media, specific hazards, and firefighter protection
Use extinguishing measures that are appropriate to local circumstances and the surrounding environment.
No information available.
Oxidizer: Contact with combustible/organic material may cause fire. May ignite combustibles (wood paper, oil, clothing, etc.). Thermal decomposition can lead to release of irritating gases and vapors. Keep product and empty container away from heat and sources of ignition.
Firefighter Protection
As in any fire, wear self-contained breathing apparatus pressure-demand, MSHA/NIOSH (approved or equivalent) and full protective gear.
Accidental Release Measures
Spill cleanup procedures, containment, and environmental protection
Should not be released into the environment.
Sweep up and shovel into suitable containers for disposal.
Materials: suitable containers

Handling and Storage
Safe handling precautions, storage conditions, and workplace requirements
Wear personal protective equipment/face protection. Ensure adequate ventilation. Avoid ingestion and inhalation. Avoid dust formation. Do not get in eyes, on skin, or on clothing. Keep away from clothing and other combustible materials.
Keep containers tightly closed in a dry, cool and well-ventilated place.
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 clothing and other combustible materials.
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: Butyl rubber (Breakthrough time: > 480 minutes, Glove thickness: 0.5 mm, EU standard: EN 374 Level 6, Glove comments: As tested under EN374-3 Determination of Resistance to Permeation by Chemicals), Nitrile rubber, Neoprene, PVC.
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. 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. Recommended Filter type: Particulates filter conforming to EN 143. Small scale/Laboratory use: Maintain adequate ventilation No personal respiratory protective equipment normally required
Long sleeved clothing.
