Thank you for your response....
I have three scenarios.
Extinguish all ignition sources. Avoid sparks, flames, heat and smoking.
Ventilate.
(In this case it should remove the period after Ventilate)
Provide ventilation and confine spill. Do not allow runoff to sewer.
(In this case it should remove the period after sewer)
Keep away from ... (incompatible materials to be indicated by the
manufacturer)
(In this case ... is a variable and should be replaced with .?)
Can you help?
