First Aid Measures

Emergency procedures for chemical exposure incidents

Inhalation

If breathed in, move person into fresh air. If not breathing, give artificial respiration. Consult a physician.

Skin contact

Wash off with soap and plenty of water. Take victim immediately to hospital. Consult a physician.

Eye contact

Rinse thoroughly with plenty of water for at least 15 minutes and consult a physician. Continue rinsing eyes during transport to hospital.

Ingestion

Do NOT induce vomiting. Never give anything by mouth to an unconscious person. Rinse mouth with water. Consult a physician.

Immediate Medical Attention

Consult a physician.

05

Firefighting Measures

Extinguishing media, specific hazards, and firefighter protection

Suitable media

Use water spray, alcohol-resistant foam, dry chemical or carbon dioxide.

Firefighter Protection

Wear self contained breathing apparatus for fire fighting if necessary.

06

Accidental Release Measures

Spill cleanup procedures, containment, and environmental protection

Emergency procedures

Evacuate personnel to safe areas. Beware of vapours accumulating to form explosive concentrations. Vapours can accumulate in low areas.

Environmental

Prevent further leakage or spillage if safe to do so. Do not let product enter drains. Discharge into the environment must be avoided.

Cleanup methods

collect with an electrically protected vacuum cleaner or by wet-brushing and place in container for disposal according to local regulations

07

Handling and Storage

Safe handling precautions, storage conditions, and workplace requirements

Handling

Avoid contact with skin and eyes. Avoid inhalation of vapour or mist. Keep away from sources of ignition - No smoking. Take measures to prevent the build up of electrostatic charge.

Storage

Keep container tightly closed in a dry and well-ventilated place. Containers which are opened must be carefully resealed and kept upright to prevent leakage.

Fire prevention

Keep away from sources of ignition - No smoking. Take measures to prevent the build up of electrostatic charge.

08

Exposure Controls / PPE

Occupational exposure limits, engineering controls, and protective equipment

Hands

Handle with gloves. Gloves must be inspected prior to use. Use proper glove removal technique (without touching glove's outer surface) to avoid skin contact with this product. Dispose of contaminated gloves after use in accordance with applicable laws and good laboratory practices. Wash and dry hands. Full contact: Material: butyl-rubber, Minimum layer thickness: 0.3 mm, Break through time: 480 min, Material tested: Butoject® (KCL 897 / Aldrich Z677647, Size M). Splash contact: Material: Nature latex/chloroprene, Minimum layer thickness: 0.6 mm, Break through time: 30 min, Material tested: Lapren® (KCL 706 / Aldrich Z677558, Size M). data source: KCL GmbH, D-36124 Eichenzell, phone +49 (0)6659 87300, e-mail sales@kcl.de, test method: EN374. If used in solution, or mixed with other substances, and under conditions which differ from EN 374, contact the supplier of the CE approved gloves. This recommendation is advisory only and must be evaluated by an industrial hygienist and safety officer familiar with the specific situation of anticipated use by our customers. It should not be construed as offering an approval for any specific use scenario.

Eyes

Tightly fitting safety goggles. Faceshield (8-inch minimum). Use equipment for eye protection tested and approved under appropriate government standards such as NIOSH (US) or EN 166(EU).

Respiratory

Where risk assessment shows air-purifying respirators are appropriate use a full-face respirator with multi-purpose combination (US) or type ABEK (EN 14387) respirator cartridges as a backup to engineering controls. If the respirator is the sole means of protection, use a full-face supplied air respirator. Use respirators and components tested and approved under appropriate government standards such as NIOSH (US) or CEN (EU).

Skin/Body

Complete suit protecting against chemicals. The type of protective equipment must be selected according to the concentration and amount of the dangerous substance at the specific workplace.
