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. If not breathing, give artificial respiration.
Symptoms: Difficulty in breathing. Inhalation of high vapor concentrations may cause symptoms like headache, dizziness, tiredness, nausea and vomiting
Wash off immediately with plenty of water for at least 15 minutes. Get medical attention.
Rinse immediately with plenty of water, also under the eyelids, for at least 15 minutes. Get medical attention.
Do NOT induce vomiting. Call a physician or poison control center immediately.
Immediate Medical Attention
Immediate medical attention is required. Get medical attention. Call a physician or poison control center immediately.
Medical Treatment
Treat symptomatically.
Firefighting Measures
Extinguishing media, specific hazards, and firefighter protection
CO₂, dry chemical, dry sand, alcohol-resistant foam. Water mist may be used to cool closed containers.
No information available.
Flammable. Containers may explode when heated. Vapors may form explosive mixtures with air. Vapors may travel to source of ignition and flash back. Containers may explode when heated.
Thermal decomposition can lead to release of irritating gases and vapors.
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
Do not flush into surface water or sanitary sewer system.
Soak up with inert absorbent material.

Handling and Storage
Safe handling precautions, storage conditions, and workplace requirements
Wear personal protective equipment/face protection. Do not get in eyes, on skin, or on clothing. Avoid ingestion and inhalation. Keep away from open flames, hot surfaces and sources of ignition. Use only non-sparking tools. Take precautionary measures against static discharges. To avoid ignition of vapors by static electricity discharge, all metal parts of the equipment must be grounded.
Keep containers tightly closed in a dry, cool and well-ventilated place. 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 open flames, hot surfaces and sources of ignition. Use only non-sparking tools. Take precautionary measures against static discharges.
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. Use explosion-proof electrical/ventilating/lighting/equipment. 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: Viton (R) (< 133 minutes, 0.70 mm, Level 4, Permeation rate 14 μg/cm2/min), Butyl rubber (< 50 minutes, 0.635 mm, Level 2, Permeation rate 161 μg/cm2/min). EU standard: EN 374. As tested under EN374-3 Determination of Resistance to Permeation by Chemicals. Inspect gloves before use. Please observe the instructions regarding permeability and breakthrough time which are provided by the supplier of the gloves. Ensure gloves are suitable for the task: Chemical compatability, 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)
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: Particulates filter conforming to EN 143 or Ammonia and organic ammonia derivatives filter Type K Green 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
