First Aid Measures

Emergency procedures for chemical exposure incidents

Inhalation

Remove from exposure, lie down. Remove to fresh air. If not breathing, give artificial respiration. Immediate medical attention is required.

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. Immediate medical attention is required.

Symptoms: May cause allergic skin reaction. Causes burns.

Eye contact

Immediate medical attention is required. Rinse immediately with plenty of water, also under the eyelids, for at least 15 minutes.

Symptoms: Causes burns.

Ingestion

Do NOT induce vomiting. Call a physician immediately. Clean mouth with water.

Symptoms: Ingestion causes severe swelling, severe damage to the delicate tissue and danger of perforation.

Immediate Medical Attention

Immediate medical attention is required.

Medical Treatment

Treat symptomatically.

07

Handling and Storage

Safe handling precautions, storage conditions, and workplace requirements

Handling

Do not breathe mist/vapors/spray. Do not get in eyes, on skin, or on clothing.

Storage

Keep in a dry, cool and well-ventilated place. Keep container tightly closed. Corrosives area.

08

Exposure Controls / PPE

Occupational exposure limits, engineering controls, and protective equipment

Engineering

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

Hands

Protective gloves. Glove materials: Natural rubber, Butyl rubber, Nitrile rubber, Neoprene, PVC. Breakthrough time: See manufacturers recommendations. 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.

Eyes

Goggles

Respiratory

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
