First Aid
A.skin contact:immediately remove
all contaminated clothing and wash the exposed areas
thoroughly with water or 2% sodium bicarbonate solution
for at least 15 minutes. Call medical help if burnt.
B.eyes contact:if acid contacts the eyes, they should
be irrigated immediately with an abundant amount of
water or 2% sodium bicarbonate solution for at least
15 minutes. Call medical help if burnt.
C.inhalation:remove the person from the contaminated
area. Administer artificial respiration if necessary
and use the atomized 2-4% sodium bicarbonate for inhalation.
Call medical help if necessary.
D.iungestlon:
gargle with water and drink plenty of water, milk, egg
white or plant oil and so on. Do no induce vomiting.
Get prompt medical help.
Safety Measures:
A.process control:close operation,
take necessary ventilation, carry out mechanization
and automatic.
B.respiratory protection:None is normally required,
however, if misting or heavy vapor formation should
occur, a approved mist respirator should be worn.
C.eye protection:chemical splash goggles and face shield.
D.skin protection:wear impervious and/or waterproof
rubber or plastic exposure suit and gloves.
E.other protection:go to shower bath after working and
keep better sanitary habit.
