GHS Hazard and Precautionary Statements

Hazard Statements: H226-H261-H304-H312-H314-H332-H335-H373

Flammable liquid and vapour. In contact with water releases flammable gas. May be fatal if swallowed and enters airways. Harmful in contact with skin. Causes severe skin burns and eye damage. Harmful if inhaled. May cause respiratory irritation. May cause damage to organs through prolonged or repeated exposure.

Precautionary Statements: P210-P223-P231+P232-P233-P235-P240-P241-P242-P243-P260-P264b-P271-P280-P303+P361+P353-P304+P340-P305+P351+P338-P310-P330-P331-P335+P334-P363-P370+P378q-P501c

Keep away from heat/sparks/open flames/hot surfaces. - No smoking. Keep away from any possible contact with water, because of violent reaction and possible flash fire. Handle under inert gas. Protect from moisture. Keep container tightly closed. Keep cool. Ground/bond container and receiving equipment. Use explosion-proof electrical/ventilating/lighting/ equipment. Use only non-sparking tools. Take precautionary measures against static discharge. Do not breathe dust/fume/gas/mist/vapours/spray. Wash face, hands and any exposed skin thoroughly after handling Use only outdoors or in a well-ventilated area. Wear protective gloves/protective clothing/eye protection/face protection. IF ON SKIN (or hair): Remove/Take off immediately all contaminated clothing. Rinse skin with water/shower. IF INHALED: Remove to fresh air and keep at rest in a position comfortable for breathing.
