First Aid Measures
Emergency procedures for chemical exposure incidents
Remove from exposure, lie down. Remove to fresh air. If not breathing, give artificial respiration.
Wash off immediately with plenty of water for at least 15 minutes.
Rinse immediately with plenty of water, also under the eyelids, for at least 15 minutes.
Call a physician immediately.
Symptoms: Ingestion causes severe swelling, severe damage to the delicate tissue and danger of perforation.
Immediate Medical Attention
Immediate medical attention is required for eye contact, skin contact, and inhalation. Call a physician immediately for ingestion.
Medical Treatment
Treat symptomatically.
Firefighting Measures
Extinguishing media, specific hazards, and firefighter protection
Carbon dioxide (CO₂). Dry chemical. Chemical foam.
Do not use a solid water stream as it may scatter and spread fire.
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.
Prevent further leakage or spillage if safe to do so.
Sweep up and shovel into suitable containers for disposal.

Handling and Storage
Safe handling precautions, storage conditions, and workplace requirements
Do not breathe dust. Do not get in eyes, on skin, or on clothing.
Keep in a dry, cool and well-ventilated place. Keep container tightly closed. Corrosives area. Store under an inert atmosphere.
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.
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. 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, Neoprene, Natural rubber, PVC. Breakthrough time: See manufacturers recommendations. EU standard: EN 374. (minimum requirement)
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. 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: Particle filtering: EN149:2001. When RPE is used a face piece Fit Test should be conducted
Wear appropriate protective gloves and clothing to prevent skin exposure. Inspect gloves before use. Please observe the instructions regarding permeability and breakthrough time which are provided by the supplier of the gloves. (Refer to manufacturer/supplier for information) 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.
