First Aid Measures
Emergency procedures for chemical exposure incidents
Remove to fresh air. Do not use mouth-to-mouth method if victim ingested or inhaled the substance; give artificial respiration with the aid of a pocket mask equipped with a one-way valve or other proper respiratory medical device. Immediate medical attention is required. If not breathing, give artificial respiration.
Wash off immediately with plenty of water for at least 15 minutes. Immediate medical attention is required.
In the case of contact with eyes, rinse immediately with plenty of water and seek medical advice.
Do NOT induce vomiting. Call a physician or poison control center immediately.
Immediate Medical Attention
Immediate medical attention is required.
Medical Treatment
Treat symptomatically.
Firefighting Measures
Extinguishing media, specific hazards, and firefighter protection
Water spray, carbon dioxide (CO2), dry chemical, alcohol-resistant foam.
No information available.
Thermal decomposition can lead to release of irritating gases and vapors.
As in any fire, wear self-contained breathing apparatus pressure-demand, MSHA/NIOSH (approved or equivalent) and full protective gear.
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

Handling and Storage
Safe handling precautions, storage conditions, and workplace requirements
Use only under a chemical fume hood. Wear personal protective equipment/face protection. Do not get in eyes, on skin, or on clothing. Do not breathe mist/vapors/spray. Do not ingest. If swallowed then seek immediate medical assistance.
Keep containers tightly closed in a dry, cool and well-ventilated place. Protect from direct sunlight.
Handle in accordance with good industrial hygiene and safety practice.
Exposure Controls / PPE
Occupational exposure limits, engineering controls, and protective equipment
Use only under a chemical fume hood. Ensure adequate ventilation, especially in confined areas. Ensure that eyewash stations and safety showers are close to the workstation location. 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. (minimum requirement). Inspect gloves before use. observe the instructions regarding permeability and breakthrough time which are provided by the supplier of the gloves.
Tight sealing safety goggles (European standard - EN 166)
When workers are facing concentrations above the exposure limit they must use appropriate certified respirators. To protect the wearer, respiratory protective equipment must be the correct fit and be used and maintained properly. 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: Organic gases and vapours filter Type A Brown conforming to EN14387. Small scale/Laboratory use: Use a NIOSH/MSHA or European Standard EN 149:2001 approved respirator if exposure limits are exceeded or if irritation or other symptoms are experienced. Recommended half mask:- Valve filtering: EN405; or; Half mask: EN140; plus filter, EN 141 When RPE is used a face piece Fit Test should be conducted
