Emergency First Aid Measures
Critical first aid procedures for chemical exposure incidents and medical emergencies
🫁 Inhalation Exposure
If breathing is difficult, give oxygen. 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. Remove from exposure, lie down. Call a physician immediately.
🖐️ Skin Contact
Wash off immediately with plenty of water for at least 15 minutes. Remove and wash contaminated clothing and gloves, including the inside, before re-use. Call a physician immediately.
👁️ Eye Contact
Rinse immediately with plenty of water, also under the eyelids, for at least 15 minutes. Immediate medical attention is required.
🍽️ Ingestion/Swallowing
Do NOT induce vomiting. Never give anything by mouth to an unconscious person. Clean mouth with water. Call a physician immediately.
Symptoms:
Ingestion causes severe swelling, severe damage to the delicate tissue and danger of perforation
🚨 Immediate Medical Attention Required
Immediate medical attention is required. Asphyxia from glottal edema may occur. Marked decrease in blood pressure may occur with moist rales, frothy sputum, and high pulse pressure.
Medical Treatment
Possible perforation of stomach or esophagus should be investigated. Treat symptomatically.

Exposure Controls & Personal Protective Equipment (PPE)
Occupational exposure limits, engineering controls, and required safety equipment
🏭 Engineering Controls
Use only under a chemical fume hood. Ensure that eyewash stations and safety showers are close to the workstation location. Ensure adequate ventilation, especially in confined areas. 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 made of Neoprene (breakthrough time > 480 minutes, thickness 0.45 mm), Butyl rubber (breakthrough time > 480 minutes, thickness 0.35 mm), or Nitrile rubber (breakthrough time < 10 minutes, thickness 0.38 mm). Gloves should comply with EN 374 (as tested under EN374-3 Determination of Resistance to Permeation by Chemicals). Inspect gloves before use and observe instructions regarding permeability and breakthrough time provided by the supplier. Ensure gloves are suitable for the task considering chemical compatibility, dexterity, operational conditions, user susceptibility, and local conditions (e.g., danger of cuts, abrasion). Remove gloves with care avoiding skin contamination.
👁️ Eye Protection
Goggles (European standard - EN 166)
😷 Respiratory Protection
When workers are facing concentrations above the exposure limit they must use appropriate certified respirators. Respiratory protective equipment must be the correct fit and be used and maintained properly. For large scale/emergency use, employ 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 Acid gases filter Type E Yellow conforming to EN14387. For small scale/Laboratory use, employ 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.
