First Aid Measures

Emergency procedures for chemical exposure incidents

Inhalation

Remove the victim into fresh air. Respiratory problems: consult a doctor/medical service.

Symptoms: EXPOSURE TO HIGH CONCENTRATIONS: Coughing.

Skin contact

Rinse with water. Soap may be used. Do not apply (chemical) neutralizing agents. Remove clothing before washing. Take victim to a doctor if irritation

Symptoms: Red skin.

Eye contact

Rinse immediately with plenty of water. Remove contact lenses, if present and easy to do. Continue rinsing. Do not apply neutralizing agents. Take victim to an ophthalmologist if irritation persists.

Symptoms: Redness of the eye tissue. ON CONTINUOUS EXPOSURE/CONTACT: Irritation of the eye tissue.

Ingestion

Rinse mouth with water. Immediately after ingestion: give lots of water to drink. Do not induce vomiting. Consult a doctor/medical service if you feel unwell.

Symptoms: Nausea. Vomiting. Diarrhoea.

05

Firefighting Measures

Extinguishing media, specific hazards, and firefighter protection

Suitable media

Small fire: Quick-acting ABC powder extinguisher, Quick-acting BC powder extinguisher, Quick-acting class B foam extinguisher, Quick-acting CO2 extinguisher. Major fire: Class B foam (alcohol-resistant), Water spray if puddle cannot expand.

Unsuitable media

Small fire: Water (quick-acting extinguisher, reel); risk of puddle expansion. Major fire: Water; risk of puddle expansion.

Specific hazards

On heating/burning: release of toxic and corrosive gases/vapours (nitrous vapours, carbon monoxide - carbon dioxide).

Instructions

Cool tanks/drums with water spray/remove them into safety. Dilute toxic gases with water spray.

Firefighter Protection

Gloves (EN 374). Protective clothing (EN 14605 or EN 13034). Heat/fire exposure: compressed air apparatus (EN 136 + EN 137).

06

Accidental Release Measures

Spill cleanup procedures, containment, and environmental protection

Environmental

Contain released product, pump into suitable containers. Plug the leak, cut off the supply.

Cleanup methods

Scoop absorbed substance into closing containers. Clean contaminated surfaces with an excess of water.

Stability and Reactivity

Chemical stability, hazardous reactions, and incompatible materials

Stability

Unstable on exposure to light. Hygroscopic. Unstable on exposure to air.

Reactivity

Temperature above flashpoint: higher fire/explosion hazard. Basic reaction.

Hazardous reactions
