appropriate protective equipment and clothing. Use small-
est amounts possible in designated areas with adequate
ventilation. Avoid generating dusts or mists (solutions). Do
not breath dust or mist. Avoid contact with eyes, skin or

and away from all incompatible and combustible materials.
Keep containers tightly closed when not in use and when
empty. Treat empty containers with caution as they may
contain hazardous residues. Protect from physical damage;
inspect frequently for signs of damage or leaking.
