First Aid Measures

Emergency procedures for chemical exposure incidents

Inhalation

Remove to fresh air. 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. Immediate medical attention is required.

Symptoms: headache, dizziness, tiredness, nausea and vomiting

Skin contact

Wash off immediately with plenty of water for at least 15 minutes. Immediate medical attention is required.

Eye contact

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

Ingestion

Do NOT induce vomiting. Call a physician or poison control center immediately.

Symptoms: 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

Treat symptomatically.

05

Firefighting Measures

Extinguishing media, specific hazards, and firefighter protection

Suitable media

Water spray, carbon dioxide (CO2), dry chemical, alcohol-resistant foam. Water mist may be used to cool closed containers.

Unsuitable media

No information available.

Specific hazards

Thermal decomposition can lead to release of irritating gases and vapors. The product causes burns of eyes, skin and mucous membranes. Flammable. Containers may explode when heated. Vapors may form explosive mixtures with air. Vapors may travel to source of ignition and flash back.

Firefighter Protection

As in any fire, wear self-contained breathing apparatus pressure-demand, MSHA/NIOSH (approved or equivalent) and full protective gear.

06

Accidental Release Measures

Spill cleanup procedures, containment, and environmental protection

Emergency procedures

Use personal protective equipment as required. Ensure adequate ventilation. Evacuate personnel to safe areas. Keep people away from and upwind of spill/leak.

Handling and Storage

Safe handling precautions, storage conditions, and workplace requirements

Handling

Wear personal protective equipment/face protection. Do not get in eyes, on skin, or on clothing. Use only under a chemical fume hood. Do not breathe mist/vapors/spray. Do not ingest. If swallowed then seek immediate medical assistance. Keep away from open flames, hot surfaces and sources of ignition. Use only non-sparking tools. To avoid ignition of vapors by static electricity discharge, all metal parts of the equipment must be grounded. Take precautionary measures against static discharges.

Storage

Keep containers tightly closed in a dry, cool and well-ventilated place. Keep away from heat, sparks and flame.

Hygiene

Handle in accordance with good industrial hygiene and safety practice. Keep away from food, drink and animal feeding stuffs. Do not eat, drink or smoke when using this product. Remove and wash contaminated clothing and gloves, including the inside, before re-use. Wash hands before breaks and after work.

Fire prevention

Keep away from open flames, hot surfaces and sources of ignition. Use only non-sparking tools. To avoid ignition of vapors by static electricity discharge, all metal parts of the equipment must be grounded. Take precautionary measures against static discharges.

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. Use explosion-proof electrical/ventilating/lighting equipment. 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 made of Nitrile rubber, with a breakthrough time of < 60 minutes and thickness of 0.38 mm, conforming to EN 374 Level 3. Permeation rate ~ 2000 g/cm2/min (as tested under EN374-3 Determination of Resistance to Permeation by Chemicals). Inspect gloves before use, observe supplier instructions for permeability and breakthrough time. Ensure suitability for task considering chemical compatibility, dexterity, operational conditions, user susceptibility, and local conditions. Remove gloves with care to avoid skin contamination.

Eyes

Goggles (European standard - EN 166)

Respiratory

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. For large scale/emergency use, a NIOSH/MSHA or European Standard EN 136 approved respirator is recommended if exposure limits are exceeded or if irritation or other symptoms are experienced, with a recommended filter type: Ammonia and organic ammonia derivatives filter Type K Green conforming to EN14387. For small scale/Laboratory use, a NIOSH/MSHA or European Standard EN 149:2001 approved respirator is recommended 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.

Skin/Body

Long sleeved clothing.

Environmental

Prevent product from entering drains.
