Emergency First Aid Measures
Critical first aid procedures for chemical exposure incidents and medical emergencies
Inhalation Exposure
Remove from exposure, lie down. Remove to fresh air. If not breathing, give artificial respiration.
Symptoms:
May cause allergy or asthma symptoms or breathing difficulties if inhaled.
Skin Contact
Wash off immediately with soap and plenty of water while removing all contaminated clothes and shoes.
Symptoms:
May cause allergic skin reaction.
Eye Contact
Rinse immediately with plenty of water, also under the eyelids, for at least 15 minutes.
Ingestion/Swallowing
Do NOT induce vomiting. Call a physician immediately. Clean mouth with water.
Symptoms:
Possible perforation of stomach or esophagus should be investigated: Ingestion causes severe swelling, severe damage to the delicate tissue and danger of perforation: Symptoms of allergic reaction may include rash, itching, swelling, trouble breathing, tingling of the hands and feet, dizziness, lightheadedness, chest pain, muscle pain or flushing
Immediate Medical Attention Required
Immediate medical attention is required.
Medical Treatment
Treat symptomatically

• Keep in a dry, cool and well-ventilated place.
• Keep container tightly closed.
• Corrosives area.
Exposure Controls & Personal Protective Equipment
Occupational exposure limits, engineering controls, and required safety equipment
Engineering Controls
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
Hand Protection
Protective gloves. Glove material: Natural rubber, Butyl rubber, Nitrile rubber, Neoprene, PVC. Breakthrough time: See manufacturers recommendations. Glove thickness: -. Glove comments: Splash protection only. 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 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. gloves with care avoiding skin contamination.
Eye Protection
Goggles
Respiratory Protection
When workers are facing concentrations above the exposure limit they must use appropriate certified respirators. Follow the OSHA respirator regulations found in 29 CFR 1910.134 or European Standard EN 149. Use a NIOSH/MSHA or European Standard EN 149 approved respirator if exposure limits are exceeded or if irritation or other symptoms are experienced. To protect the wearer, respiratory protective equipment must be the correct fit and be used and maintained properly Recommended Filter type: Particulates filter conforming to EN 143 Acid gases filter Type E Yellow conforming to EN14387. When RPE is used a face piece Fit Test should be conducted
