Remark :

6. Accidental release measures
Personal Precautions : Immediately contact emergency personnel. Keep unnecessary personnel away. Use
suitable protective equipment (Section 8).
Environmental precautions : Avoid dispersal of spilled material and runoff and contact with soil, waterways, drains
and sewers.
Methods for cleaning up : If emergency personnel are unavailable, contain spilled material. For small spills add
absorbent (soil may be used in the absence of other suitable materials) scoop up
material and place in a sealed, liquid-proof container for disposal. For large spills
dike spilled material or otherwise contain material to ensure runoff does not reach a
waterway. Place spilled material in an appropriate container for disposal.
