First Aid Measures

Emergency procedures for chemical exposure incidents

Inhalation

Remove to fresh air. 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. If not breathing, give artificial respiration.

Skin contact

Wash off immediately with soap and plenty of water while removing all contaminated clothes and shoes.

Eye contact

Rinse immediately with plenty of water, also under the eyelids, for at least 15 minutes. Keep eye wide open while rinsing.

Ingestion

Do NOT induce vomiting. Never give anything by mouth to an unconscious person. Drink plenty of water.

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

Immediate Medical Attention

Immediate medical attention is required. Call a physician or poison control center immediately.

Medical Treatment

Possible perforation of stomach or esophagus should be investigated

05

Handling and Storage

Safe handling precautions, storage conditions, and workplace requirements

Handling

Use only under a chemical fume hood. Wear personal protective equipment/face protection. Do not get in eyes, on skin, or on clothing. Do not breathe dust. Do not ingest. If swallowed then seek immediate medical assistance.

Storage

Keep containers tightly closed in a dry, cool and well-ventilated place. Corrosives area. Store under an inert atmosphere.

Hygiene

Handle in accordance with good industrial hygiene and safety practice.

08

Exposure Controls / PPE

Occupational exposure limits, engineering controls, and protective equipment

Engineering

Use only under a chemical fume hood. 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 material: Natural rubber, Nitrile rubber, Neoprene, PVC. Breakthrough time: See manufacturers recommendations. EU standard: EN 374. (minimum requirement)

Eyes

Goggles (European standard - EN 166)

Respiratory

When workers are facing concentrations above the exposure limit they must use appropriate certified respirators. 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

Skin/Body

Long sleeved clothing.

Environmental

Prevent product from entering drains.
