First Aid Measures
Emergency procedures for chemical exposure incidents
Remove to fresh air. Get medical attention immediately if symptoms occur. 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. Get medical attention.
Immediate Medical Attention
Get medical attention.
Medical Treatment
Treat symptomatically.
Firefighting Measures
Extinguishing media, specific hazards, and firefighter protection
Water spray, carbon dioxide (CO2), dry chemical, alcohol-resistant foam. Water mist may be used to cool closed containers.
Do not use a solid water stream as it may scatter and spread fire.
Flammable. Containers may explode when heated. Vapors may form explosive mixtures with air. Vapors may travel to source of ignition and flash back.
As in any fire, wear self-contained breathing apparatus pressure-demand, MSHA/NIOSH (approved or equivalent) and full protective gear. 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
Use personal protective equipment as required. Ensure adequate ventilation.
Should not be released into the environment.
Soak up with inert absorbent material. Keep in suitable, closed containers for disposal.
Materials: inert absorbent material, suitable, closed containers

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. Use spark-proof tools and explosion-proof equipment. Take precautionary measures against static discharges. Use only under a chemical fume hood. To avoid ignition of vapors by static electricity discharge, all metal parts of the equipment must be grounded.
Flammables area. Keep away from heat, sparks and flame. Keep container tightly closed in a dry and well-ventilated place. May form explosive peroxides on prolonged storage.
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: Nitrile rubber, Breakthrough time: < 211 minutes, Glove thickness: 0.38 mm, EU standard: Level 4, Glove comments: Permeation rate 1 μg/cm2/min. Viton (R), Breakthrough time: < 152 minutes, Glove thickness: 0.7 mm, EU standard: Level 4, Glove comments: Permeation rate 17 μg/cm2/min. Neoprene, EU standard: EN 374, Glove comments: As tested under EN374-3 Determination of Resistance to Permeation by Chemicals. Natural rubber. PVC.
Wear safety glasses with side shields (or 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
Wear appropriate protective gloves and clothing to prevent skin exposure. Inspect gloves before use. observe the instructions regarding permeability and breakthrough time which are provided by the supplier of the gloves. (Refer to manufacturer/supplier for information) 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. gloves with care avoiding skin contamination.
