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.

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.

Immediate Medical Attention

Immediate medical attention is required.

Medical Treatment

Treat symptomatically

05

Firefighting Measures

Extinguishing media, specific hazards, and firefighter protection

Suitable media

Carbon dioxide (CO₂), Dry chemical, soda ash or lime. Water mist may be used to cool closed containers.

Unsuitable media

Do not use water or foam

Specific hazards

Combustible material. Corrosive material. Water reactive. Contact with water liberates toxic gas. Containers may explode when heated. Thermal decomposition can lead to release of irritating gases and vapors. Keep product and empty container away from heat and sources of ignition.

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

Evacuate personnel to safe areas.

Environmental

Should not be released into the environment.

Cleanup methods

Soak up with inert absorbent material.

Materials: inert absorbent material

Related Products

Similar products with comparable safety profiles

07

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. Do not breathe mist/vapors/spray. Do not ingest. If swallowed then seek immediate medical assistance.

Storage

Keep containers tightly closed in a dry, cool and well-ventilated place.

Fire prevention

Keep away from open flames, hot surfaces and sources of ignition. Keep away from heat, sparks and flame.

08

Exposure Controls / PPE

Occupational exposure limits, engineering controls, and protective equipment

Engineering

Use only under a chemical fume hood. Ensure adequate ventilation, especially in confined areas. Ensure that eyewash stations and safety showers are close to the workstation location.

Hands

Wear appropriate protective gloves

Eyes

Wear appropriate protective eyeglasses or chemical safety goggles as described by OSHA's eye and face protection regulations in 29 CFR 1910.133 or European Standard EN166.

Respiratory

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.

Skin/Body

Wear appropriate protective clothing to prevent skin exposure.
