Emergency First Aid Measures
Critical first aid procedures for chemical exposure incidents and medical emergencies
🫁 Inhalation Exposure
If not breathing, give artificial respiration. 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 to fresh air.
Symptoms:
Asphyxia from glottal edema may occur. Marked decrease in blood pressure may occur with moist rales, frothy sputum, and high pulse pressure.
🖐️ Skin Contact
Wash off immediately with plenty of water for at least 15 minutes.
👁️ 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 or poison control center 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 for all exposure routes. Call a physician or poison control center immediately for ingestion.
Medical Treatment
Treat symptomatically. Possible perforation of stomach or esophagus should be investigated.

Exposure Controls & Personal Protective Equipment (PPE)
Occupational exposure limits, engineering controls, and required safety equipment
🏭 Engineering Controls
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. Glove material: Neoprene gloves - Breakthrough time: 480 minutes, Glove thickness: 0.45 mm, EU standard: EN 374, Glove comments: As tested under EN374-3 Determination of Resistance to Permeation by Chemicals, Level 6. Butyl rubber - Breakthrough time: 480 minutes, Glove thickness: 0.56 mm, EU standard: EN 374, Glove comments: Level 6. Viton (R) - Breakthrough time: 480 minutes, Glove thickness: 0.7 mm. Butyl rubber - Breakthrough time: 480 minutes. 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.
👁️ Eye Protection
Goggles (European standard - EN 166)
😷 Respiratory Protection
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 Acid gases filter Type E Yellow 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
